Strange Automotive Engines: International's (IH) "Half of a V8" Comanche 152/196ci 4cyl!

Learn more about the International-Harvester "half of a V8" Comanche engines!

[@billjamison2877]

My family owned an autoboby repair shop. We had a 1961 Scout, with this unique engine, set up as a snow plow and tow truck. My grandfather bought it new in 1961. It was a blast to drive! Power nothing, vacuum wipers and sliding half windows in the doors. The gearing was insane. In Granny gear, the torque felt like you could pull a house off its foundation! When my father retired in 2005, the Scout had 13,200 original miles on it!!!!! My uncle, living in Texas, drove to Pennsylvania with a flatbed and hauled it back to Texas. The Scout lives on!!

[@giggiddy]

Love the story and you have a cool family. 😊

[@nferraro222]

Never had a Scout, but I loved the ScoutII's. The 304's were unbelievably bulletproof, due to their extremely thick cylinder walls, forged cranks and nickel-alloy blocks and gear-drive cams.

[@joesutherland225]

The best by far for longevity as you could bore them over and over if you had to,but never really needed great motor

[@jeffharper7579]

Back in the mid 80s I drove a ih one ton truck for waterproofing fountains ,it had the 304 in it I feel it was just as good as a 350 but a tad easier on gas. I miss that truck, should have bought it when boss man asked me if I wanted it😞

[@randalllindemann3545]

I owned two Scout IIs and two IH pick-ups. One Scout had the 196 four cylinder. That one ran a bit rough on acceleration. The one with the 304 V-8 was much nicer. It kinda broke my heart when IH quit making those vehicles. I still have a 560 Farmall (same 232 c.i. six cylinder engine as my 1951 IH pick-up) that I drove home new from the dealer at age 11 when my dad bought it in 1963. Finally, I’ve driven hundreds of thousands of miles over the road in International semi tractors. International Harvestor is a big part of my life.

[@Al-thecarhistorian]

You have touched a soft spot in me because in 1964 when I was 16 my parents bought a new International Scout all-wheel-drive. At the time I thought it was the most useful vehicle I had ever seen. Liked it so much better than the Mustang. We had the Scout for eight years and except for rust, very little went wrong with the Scout. I learned to drive stick shift on the Scout and we spent many times romping through snow in the winter and going camping in the summertime. I do not recall the four cylinder vibrating much. I loved the sound it made on take off. it sounded a bit like a farm tractor and had a chugging note to it. Indeed, it was bare-bones, although with ours, we did get the optional roll down windows and a heater and defroster. The only peculiarity it had was when it rained occasionally it would stall when you came to a stop. It was in the shop for that a number of times, but they claimed they could never find a problem. It did rust out, unfortunately after eight years as it occasionally leaked around the windshield. I also remember the steering wheel was on crooked from the factory. Instead of the bars going horizontally, they went vertically up and down. My father sold our Scout in 1972 to a friend up the street who fixed the rust in the floorboards, and had the Scout re-painted from the original tan with a white top to red with a white top. He drove it for another 10 years before he got rid of it. It was the greatest vehicle any teenager could've ever grown up with.

[@allencheck501]

I had a 64 ih syep van with the sawed off four three speed stick through top of tranny military still had all the nomenclature tags that was the coolest hunting camping fishing, boon docking wagon ever made would go any where (just not real fast) wish i still had it!

[@jaygraham5407]

I bought a 1963 Scout in the fall of 1971. It had a snow plow on it. Rear end was out of it. Was fortunate to find a used rear end. Ran the Scout until it was severely rusted out to the point that the passenger seat was falling through the floor. I found a 1965 Scout right hand drive with own motor. The body was in good condition. I swapped the body onto the 63 chassis. Swapped all the controls and dash and everything into the 65 body. Made new foor pans and bed floor. Completed the project in 1978. Ran it until 1985 and sold it for the same amount of money I originally paid for it. Plowed lots of snow with. Wish I still had this Scout.

[@dennisfoltz7880]

We lived in a wooded area at the end of the road . Me and older brother would take one of my dads 2 wheel drive trucks into the woods on old oil lease roads . We would sometimes get stuck and need pulled out . We would alway go get our elderly neighbor and his little scout truck to pull us . He never complained or told our dad. We were in our teens in the seventies. The poor neighbor was in his eighties, wonderful man . Never forget his little scout truck . Hopefully someday ill find one i can restore

[@wakeup6910]

The old guy had fun too 😉

[@LBS4]

This is fantastic - my first vehicle was a 1980 Scout 2, factory yellow with half a V8 and a 4 speed. My brother and I ran it for years then I drove it out to CO and sold it while out there. I miss that truck!

[@jefferysmith3930]

My grandfather kept an old 4 cylinder mid 60’s Scout for decades at my grandparents NC summer home to serve as his mountain runabout. He loved it. It would sit in a rickety garage for 6 months every year during the winter and fire right up with a little coaxing when they returned in the spring. Other than having an automatic transmission, it was about as crude as a vehicle could get with dented body panels and a floppy soft top. He couldn’t have cared less. It suited him perfectly.

[@jefweb5043]

I'm so glad you featured IH!! Don't forget about the Nissan powered diesel they offered. Absolutely zero power, but unreal fuel economy. Keep in mind, while not perfect, International carried over a lot of the durability and toughness from their ag lines to their vehicles. They didn't fair so well against rust, but tough as nails.

[@michaelmurphy6869]

As per the rust issue that plagued International was because of the lack of galvanizing on the sheet metal used in their body parts. Along with fit and finish which was a little crude, definitely not award winning to say the least. Probably a cost-cutting measure by the top brass. International along with Dodge pickups (at the time circa 70's) were known for having weak bodies but bulletproof powertrains.

[@member57]

​@@michaelmurphy6869 IH bought cheap steel in bulk from France and stored outside.

[@JeffK.]

I was wondering if somebody was going to bring that up. Power be damned, people were looking for cheap fuel and good fuel economy at that time ('78-'79 I think).

[@WE500CD]

196 owner here! 78 Scout Terra. Very reliable. Won't win a race but does great. It's a little shakey LOL!!! My 392 in the my 75 Travelall is super smooth.

[@VB-bk1lh]

I had a slant 4 engine in my '67 Scout. I did just fine powerwise and it was stronger than a same period 4 cyl. Jeep. I had the '67 in the early 80's, I bought it from a farmer who had it that retired and was selling off all his equipment. It ran just fine but even then, parts were an issue. At around 146k on the clock I pulled the motor for an overhaul. The cam was basically a V8 cam minus half its lobes, but since the original cam couldn't be found, we used one from a V8. The cam we found didn't have the fuel pump lobe, so from then on it lived with a small cube type fuel pump. The distributor was the same as a V8, but with every other plug wire socket devoid of its contacts and filled in. Not being able to find the original cap, we used a V8 cap and simply filled every other port with RTV. It worked fine. I had that Scout till around 1990 or so, along the way I had picked up a parts truck for various items, mostly because it was super cheap. I had offered it to the guy who bought the '67 but he wasn't interested. Four years later I stumbled on a good running IH V8 and I put the V8 into the 1965 scout and used it mostly just for fun for a few years before other issues with it made me lose interest and it too got sold in favor of something with ac and a stereo.

[@geofjones9]

A friend had one of those Scouts. Don't know if it was the 152 or 196. It was not a fast car, but it would really lug. Had 3 speed floor shift, posi in the rear, plus 4 wheel drive with a low range. Had to spin both rears and one front before you were stuck. The engine was very durable, had medium-duty truck engine parts inside. That little car had a heart of gold!

[@Krankie_V]

When I was a kid my dad's plow truck was an International Scout with one of those slanted 4 cylinders.

[@Studio17480]

I worked for IH as a field rep the late 70s and we were provided with new Scouts every year. Internally at IH, they were called “ETVs (employee travel vehicles) I had several 1978, 79 and 1980 Scout IIs. They had 304 and 345 v8s. All the V8 scouts came with standard dual exhaust , and they sounded amazing. Most were upper trim models, all with chrome rims, whitewalls and deluxe interiors. I’ve seen many restorations, but very few retain the original details such as correct decals, the whitewall tires and chrome Rally rims. I really loved driving them. Thanks Adam love your channel and the fascinating details !

[@MarkPietz-l2v]

Just stumbled onto this video. My comment here is to clarify that the picture of the Scout 152 engine with the partial turbo (and disconnected outlet pipe to the right) is not a picture of the actual turbo option installed in the 1965-67 Scouts. It's a picture from a "turbo" Scout project I had around 2016. I was mocking up 152T turbo exhaust manifolding mounted to the larger IH 196 in a 1980 Scout II engine bay, to check for clearances and feasibility. My project was successful, but short lived.

[@anthonyflannery4995]

My first driving experience Was in my dad's 61 scout when i was 12. We also had a 73 travelall in the late 70's ,sold it in 83. Scout was posi front and rear, would clinb anything!

[@bradreinhardt1358]

Don't hear enough about IH vehicles. When I worked on them in the 70s, I was impressed with how robust they were designed. I never experienced any driveability issues with them. They were just solid!

[@michaelmurphy6869]

One of my old bosses had a international/AMC dealership in Oregon back in the early to late 70's. He'd say that was his funnist time in the car business, both companies were easy and fun to deal with and would give him anything he wanted for product. He could only remember one instance of one of his customers that had engine issue with a '74 Travel-All in which the engine (392) failed due to overheating. He couldn't recall exactly what caused the overheating issue, but they replaced the engine under warranty and International never questioned it. The biggest issue he'd seen at the time was "squeeks and rattles" and fit and finish (mainly water leaks)of the doors, windows, fenders, etc. He had said the bodies were crudely assembled which wasn't a big problem and a few rust issues that was because that International didn't galvanize their sheet metal for their body parts other then that they were great vehicles.

[@gungadinn]

I've owned a 60 Scout 800A with the Big 196 cu/in 4 banger and a 78 Scout II Terra with all the options powered by a 345 cu/in V-8. The 800A was minimalist, no power steering or brakes. It did have good heat though. Too bad that International never found a way to keep them from returning to the earth as a pile of rust. International Engines all share parts. the 152 shared all the engine internals with the 304 V-8, and the 196 shared with the 392 V-8. The 304 and the 345 shared some parts and the 345 and the 392 shared some parts. With all International trucks, you needed the date of manufacture and the VIN number, as their parts suppliers changed during the model year. They did however have very good configuration management, so as long as you have the DOM and VIN, you got the right part the first time.

[@georgeheaver5687]

My first truck was a Scout Terra with the 196. Lived in MT and it would always start for me. Had a -50 morning and it complained a little, but started.

[@jamessharp9790]

I Can’t say how much I enjoy your channel . The way you present information with no hype is refreshing. I’m 55 and a lifelong gear head, it’s annoying when some there’s some real engine family 101 stuff presented as if it’s more esoteric information. You don’t do that, I’ve been able to learn expanded knowledge on basic w Glen families I knew and become aware of some others. I also like your car collection in that you stay away from the more popular muscle and pony cars.

In 1972 I traded a VW bug for a 1970 4 cylinder Scout with the full roof. I was in the USAF and my drive home went from 9 hours in the VW to 12 hours in the Scout. It was not a road trip vehicle and was like riding in a steel drum at 55-60 mph top speed! I traded it for a Pinto when I got married later that year. I sure do wish I had the old Scout today!

[@scootertrash911]

Can't believe you survived owning a Pinto, otherwise known as the dynamite car./sarc

[@kevinvoyer5053]

Once again my friend awesome video. Being a former owner of one Scout 800, that was my uncle’s before mine, he was the original owner that had bought it for hunting up north. With the 304 V8,4speed with the tallest 3:04 gears for highway cruising. Plus he plowed a LOT of snow on his property and street. Then I inherited it and drove for one year, then traded it in on. Used 73 Scout II in 76, that had the 258 AMC straight six, 727 automatic with one speed silent drive transfer case, with locking rear. That really wasn’t needed anywhere but ice/snow, because of the lack of torque to the ground, but it cruised all day at 70 easily and never used any oil. But I got tiered of having my friends get out to push on the beaches in deep sand, not because we got stuck, as I had 30-12.50-15 tires, but the lack of torque without low range. So I special ordered a 78 SCOUT II TERRA, 4 x4, 345 V8 dual exhaust, HD 727, HD Borg Warner 2 speed transfer. With 3:52 Detroit Tru Trac, in a Select Edition that was like the brown and gold one in the video, but mine was black and gold, with white removable cab roof, with two roll bars, one in the bed, one in the cab. With a 2” lift, 32/10.50-15 GoodYear Tracker tires. The factory grill/brush guard, and three HD skid plates from under the front bumper and under the axle, then oil pan to trans/transfer case and gas tank to ream bumper, plus trailer hitch. I added the biggest KONI shocks I’ve ever seen and Cebia Z Beam halogen headlights, which two KC DayLighters on the grill, 2, Cebia BiOscars on the grill that were driving and fog lights, plus a remote spotlight mount just above the windshield in the center of the can roof. With a KC DayLighter sealed bulb with 400,000 candle power, for a total of over 1,750,000 candle Power all together without the headlights. On a local beach on a dark night I could light up the entire beach from low tide line to the top of the dunes for as far as I could see, on a 4 mile stretch. The spotlight on the roof could light up a boat at least a mile off shore. At night pulling up to a friends apartment on the third floor coming up the hill from a quarter mile away I could light up his entire apartment like he had every light on! The lights were all so powerful it was a good thing I didn’t have AC, because I had to mount a second 180 amp, $250 custom wired and installed alternator and second battery just to keep them on for a few minutes at a time! Now with LED’s it’s nothing, but I had enough amps to weld with! The ONLY trouble with International vehicles was rust/rot. I even had the 78 TERRA Zeibart “rust proofed”, with the top of the line bumper to bumper lifetime coverage. When I went in for a claim in six years when all of a sudden after winter I noticed each fender and taillights showing signs of rusting? I was told sorry bout yer bad luck buddy to much driving on the beach!!! Even though the truck was meticulously maintained and cleaned and waxed and bottom rinsed all the time, looking like new as you walk up from across the parking lot! If I were to build one now? I would seriously consider using a fiberglass tub and front end. With a roll cage and re-enforcements.

One of my fathers colleagues, who we did a lot of camping with, had a brand new loaded Geen with White top, 1966 Travelall, which was still really basic. Our Boy Scout troop that Travelall and dad's 1963 International (IHC) C-1100, with a DIY chassis mount camper took our Boy Scout troop to San Felipe, Baja California. We all called it the 'Super Pickle', seriously fond memories.

[@crusinscamp]

I love the every-other-terminal on the distributor blocked off at 8:34 . I had a '68 with the small V8 in the late '70s, it was red with a white top, of course. I did have to repair a lot of rust, but mechanically it was solid. It may not have been the most luxurious ride, but it always got me there and we had fun with it. I remember on highway trips, after the engine warmed up and settled in, the engine emitted a busy subtle mechanical sound. That engine had a song of it's own. One of the more favored vehicle I have owned.

[@5695q]

Owned three Travelall's over the years, they were all the 1200/1210 3/4 ton models. When California started charging several hundred dollars to register a pickup and it would have to have a commercial plate, I could register my 'binder for about 35 dollars as a 3/4 ton station wagon. They sucked gas but would haul a load and keep it out of the rain plus if you went camping, you could put the air mattress in the back and have plenty of room for your gear.

When I was a kid just out of high school I purchased a 2wd 1965 Scout from an older man for the sum of $300. I drove that Scout for over a year and put 2 reman mud tires on the rear. It had cruise control, but no heater or a/c. The cruise control was a knob that was on the dash that was connected to the carburator. It had a top speed or almost 100 mph and had 2 10 gallon gas tanks. That old Scout never gave me any trouble with the exception of a front wheel bearing. I sold it to as used car dealer for $350. In 1973 I ordered a 4x4 Scout with a 4 speed tranny, auto locking hubs, a/c, 345 cu in engine with dual exhaust and 3:31 gears which was a mistake thinking the gearing would give me better gas mileage, but once I put taller tires on it, it lost a lot of power which required more gas. I should have opted for the 3:73 or 4:11.

I had a '61 Chevy Apache 10 Fleetside with cruise control. All old trucks had it. It was called the throttle cable. Pulled the knob out to get the desired speed and took my foot off the gas.

We were given the use of an 63 Scout in Arizona from my friend's dad who bought it at a farm auction. We took that thing everywhere off road and to work and back etc. It was very basic with a AM radio and a heater. It was a work horse and a utility jeep.

Thank you for recognizing international harvester they were a main player in the development of tractors machinery excavating equipment trucks and vehicles during this time period. Right after world war II they came out with the international TD 24 bulldozer my uncle owned one and mined coal with it. Largest dozer when it came out. It started on gas and you pulled a lever to switch over to diesel but this technology in the 1940s caused a lot of problems for international because it would break and bust the heads over time. They eventually sold their excavating line to Dresser and then to Dresta, which is a Polish company and still producing the TD 25 a derivative of the TD 24.

I pulled a 401 AMC v8 from a old rusted IH pickup and rebuilt it and put it in my 74 Jeep CJ5. Fantastic power with just a few mods.Induction and Cam being the most important . The Comp 268H is absolutely perfect for the 401 in my opinion. The midrange power is perfect but really it really never stops pulling hard from idle to 5000 rpm It's just noticed the most from about 1200 - 4500 . Cruising at 2500 at 65 mph I can just step on it lightly and in a few seconds it's at 4000 and 100 mph with 3.73 gears and 35" tires. I've no idea how fast it is because I've never stayed in it longer than I needed to getting around someone on the highway. But it's got absolutely no problem frying 33" tires just looking at the gas pedal at a stoplight

Those early Scouts were also sold in Australia. The then GPO or today's Australia Post bought quite a few of them for deliveries and pickup in rural areas that were not to far but had difficult access. I believe they came over as CKD kits and were assembled in the IH plant at Geelong. My father had one for a short time and we went places in that that surprised me. He took my brother with him on a trip to Woomera in the mid 60's as he had some warranty work to do and it rained whilst they were up there. Back in those days South Australian outback roads were no more than a path cleared by a grader and the Woomera road got a lot of use. The pictures of the return journey are epic as according to Dad they drove through hundreds of miles of ankle deep rutted mud roads. That mud was mostly made from Bull Dust so it was particularly slimy. He said to me that my brother had to get home for school so he didnt wait it out like most and they pushed on to get home. They camped out for a couple of nights gut he praised his Scout as it never got seriously bogged and he even helped drag a 5 ton Truck out that was stuck. However they were very expensive in Australia and because the British got a far better deal on import duty they couldn't compete against the Land Rovers (That were not much cheaper) or the then bargain priced Japanese 4X4's. Even though Dad worked for IH he replaced it with a Nissan Patrol that was quite capable as well.

Had a 1961 with the 152, a 1967 with the 196; much better than the 152 especially with the 4 speed. Lastly a 1970 SR2 with the AMC 232 6cyl, it was the fastest and smoothest on the road. For chugging around the Colorado mtn trails the 196 w/4spd was the best, wish I still had it!

[@bullnukeoldman3794]

I well remember when this engine appeared - I lived in Springfield, Ohio, where many residents worked at the large IH manufacturing plants in town. The Scout wasn't built here (I believe that these were built in Fort Wayne) but several local folks loyally bought them. They soon became known as underpowered rough-runners and were mostly used as farm/agricultural runabouts. Scouts with larger engines later were better accepted locally and used as grocery-getters for moms.

[@paulspeakman551]

My dad worked at the Springfield plants from 1956 to 1970. We had a couple of Travelalls in the 60's and in the late 70's I had a '73 Travelall with the 392 that looked exactly like the one pictured in this video.

Adam, thank you for covering some IH history! I can't wait to see your video on the Travelall too. Hopefully sometime you'll also get to IH pickups, Travelette, Wagonmaster, Scout Traveler, Scout Terra... I wish you could cover classic tractors and farm equipment too. With your presentation style, outstanding knowledge, and reliable accuracy, you would be better than all the youtubers currently doing it.

Had a 1970 Travelall.... It actually hade the 354 and a genuine 5-speed manual (with overdrive) very ahead of it's time!

[@tiredofit1235]

I think you mean the 345

[@TonyM132]

345 V8... But I agree about that manual trans. IH actually offered both overdrive and 5th gear direct drive 5 speed manuals back then. That was long before mainstream pickup and SUV's had 5 speeds. GM didn't offer 5 speeds in heavy pickups (they were in half tons a bit earlier) until when, late 80's or early 90's? I know you could still get a 4 speed manual in a 3/4- or 1-ton Chevy in the early 1990's. If you had a 5-speed in a light duty vehicle in the early 1970's, you had a rare machine. And if 5th gear of your 5 speed was direct drive, you have a very rare transmission for any decade!

[@brianhdueck3372]

Nice feature Adam. I used to wish they dropped the AMC 304 into these Utes. Another interesting engine IH came up with was the gas/diesel combo engine. It was never used as a road engine as far as I know but it sure was an interesting concept, as back in the day diesels were hard cold starting engines.

[@TonyM132]

IH already had their own 304 V8, which would soon be installed in Scouts. Why would you want them to use AMC's 304 instead? On your second point... Ya, that was even farther back in the day, ending in 1958 with the 450 and 650 tractors. The D282 engine which followed, IH's first direct-start diesel, was incidentally known as one of the most cold natured, hard starting diesels of the whole decade of the 1960's.

[@brianhdueck3372]

@@TonyM132 my thinking on the AMC vs IH was weight and performance. The AMC was a quick little rever while the IH characteristics were more like the truck engine it was. The weight bias favouring the AMC was almost 100 lbs. And seeing as the two companies had somewhat of a working alliance it looked like a good fit to me. As to your second point, that is as I recalled it as well. Thanks for sharing your observations. Much appreciated.

[@ExposingReflections]

They still had the start on gas, diesel engine in the '64 TD-9 tracked dozer. That engine was the same as the Super WD-9 wheeled farm tractor. That was the biggest tractor available when it came out. Bit over a hundred horse, from what I remember. Great machines. 500 psi hydraulic systems on the dozer in 64. Leather seals on the cylinders and pumps still. Massive cylinders to lift a pretty light c-frame and blade. Way way better than the cable lift on the competition machines tho. Very high tech for the. times.

[@TonyM132]

@@ExposingReflections The diesel engine in the Super WD-9, the gasoline-start 350 cu in 4-cyl, is the one I was referring to. Its use in farm tractors ended in 1958. I don't know anything about the construction equipment line, beyond that the TD-9 was a famous model. But looking it up on the tractordata site (which certainly has some errors but is generally accurate), it says the last year for the gas-start diesel in a TD-9 was 1959. And that the TD-9 ended production completely in 1962, with the direct-start D282 as its engine for its final three years. I think you're right about the Super WD-9 being the most powerful farm tractor when it debuted in 1953, but it wasn't 100 HP. Its Nebraska test in May 1954 showed 65 max belt HP. A year later, the Oliver Super 99 surpassed it with 79 belt HP from a GM/Detroit 3-71 3-cyl 2-stroke diesel. IH's gas-start 350 diesel engine continued in the model 600 and then 650 tractors through 1958, but it was not tested again or rated any higher by IH after 1954. The first conventional farm tractors to hit 100 PTO HP are generally considered the Deere 5010 in 1962 and Allis D21 in 1963. IH's first over 100 PTO HP was the 1206 in 1965.

I have an issue of Popular Science from 1976 that has a review of a Scout 2 with a 198 CI six cylinder diesel mated to a four speed manual. The zero to sixty time was 29 seconds. A Subaru wagon with an 84 CI four was a bit quicker at 24.5 seconds. A Jeep Renegade with a 304 V8 smoked them both with a 10.6 second run.

[@Tchristman100]

My Uncle had a '65 Scout with the 4 cylinder. What was unique was it had 4 gear shifts! The normal 3 speed, then an overdrive spliter, then high/low range, then in and out 2 or 4 wheel drive. Also had manual front drive hub locks. Just about the most reliable setup ever. He lived in Hawaii where speed wasn't important.

@@johneckert1365The 3.8 you refer to is simply the 3800 and the 3.3 is the 3300 reduced. They were not Chevy engines. GM did use 2.8, 3.1. & 3.4 SOHC engines used widely, and a 3.4 DOHC as well as a 3900.

[@johneckert1365]

@wymple09 You are incorrect. The Buick 3.8 is a 231, and the Chevy 3.8 is a 229. The Chevy 3.8 was only in RWD cars, never in FWD cars. It was easy to distinguish the two engines from eachother because the Chevy V6 had the distributor in the rear of the engine, identical to Chevy V8's, also all the front accessories (water pump, power steering pump, alternator, etc) were the same. There was also a CHEVY 3.3L V-6 that looked identical to the CHEVY 3.8 V-6. They have absolutely nothing in common with the Buick 3.3-3.8-4.1 family of V-6 engines. Research a 1978 Chevy Malibu, you'll find that the base engine was a 3.3 Chevrolet V6, which was basicly a 267 Chevy V8 with 2 cylinders missing. A year or so later the bore was enlarged to the 305 Chevy V8 diameter, making 229cid (3.8L). Eventually Chevrolet increased their V6 bore to thier 350 V8 diameter, giving us thier 262cid (4.3L) that was used through the mid 2000's.

[@johneckert1365]

@wymple09 You also left out Chevrolet's 3.5 V6, it in the same 60 degree V6 engine family as 2.8, 3.1, 3.4, 3.4 DOHC, and 3.9.

[@TonyM132]

Scouts were small vehicles. I can't agree with you calling them "relatively heavy". They were some of the shortest length vehicles on the road, comparable to Jeep CJ's, which were also typically powered by 4-cyl engines in the 1960's (if not Buick V6's). But I admit, people also complained about Jeeps being underpowered.

Had a custom adapter for a VW Solex (Made in W Germany) that was so fouled ended up replacing it with a no-name clone. Sat for 4 years before finally getting it running w/ a REAL (all the castings marks) Weber 32/36. Didn't drive it around as much on the trails as much as I would've liked but that thing would lug down to 300 RPM & seemed content to stay there as long as you fed it for the short time I did have it there. In 1st gear 4-LO it had no problem albeit slowly going up nearly 40deg slopes. Still have it & eventually would like to get it going again as the last time I even ran it was about 5 years ago now. A couple times a 196 came across my sight but unfortunately I was too late or it was way too far away.

Back in the Day Smokey Yunick took a Buick V6 that was originally cut down from a BUICK V8 and then cut it down to a 3-cylinder and injected and turbo'd that and made something like 350 hp and got 50 mpg. And it would fly and make sandwiches too. Or something like that...hahaha

[@grahambell4298]

Here in the UK, Vauxhall made a SOHC slant 4 that was also half of a V8. The original intention was that both 4 and 8 cylinder engines would share many parts and could therefore be built on the same production line. Unfortunately the V8 never got past the prototype stage.

[@Catfish4000]

Later Scout IIs could be ordered with the Nissan SD33T, which had 110hp (not too shabby for a 3.3L, indirect-injected, low-boost turbodiesel). However, I assume that the likely higher purchase price, plus the cheapness of gasoline vs diesel would explain why only around 6400 were sold with this combination. For an average driver, it would take many years and miles to recoup that extra cost, however farmers who already had equipment running on (possibly subsidised) diesel would benefit from having this option. I think this combo would have done very well here in Australia, where petrol prices have always been much higher, even with our currency adjusted. We did assemble Scouts in Australia, via CKD kits along with the D-series Dodge/IH medium trucks and the cab-over heavy trucks. The IH trucks were powered by the 345 and 392 petrol V8s, and the infamous Neuss diesel as well as the Cummins C-series. The electrical distribution company that I work for, back in the day, had the IH cabovers as bucket trucks and mobile cranes, powered by the 345s and 392s. A work colleague did his mechanic's apprenticeship on these and nutted out some cool hotrod tricks to really get these cranking. He took the 345 heads and put them on the 392 for more compression, bumped the cam and ignition timing up, shimmed the valve springs for more seat pressure, and tweaked the vacuum governors on the Holleys to come in at a higher rpm. The drivers were quite happy with these "refinements". Mated to an Allison AT540, they would routinely get 2 MPG (standard or modified). They were very heavy engines (heavier than most big blocks), and I assume that the 4-cylinder version you featured here would also be a very weighty lump for the amount of power it produced.

Those small Allisons (AT 540 & AT545) sure could've used a torque converter lock-up feature like the bigger ones.

I’m pondering how they would space the big end of the rods on a crank journal originally designed for two rods. Not machining half of the crankpin? Floating spacers? Assuming it’s the same crank as the parent V8. Balance would also be an issue with 4 pistons/rods missing on the crank.
