Tale Of The Super Six

[@chalonfurtado2941]

I love the slant six. My grandfather raced a valiant with a hyper pak in the early 60s in the baby grand series of nascar. I didn’t learn that until I blew a head gasket on my 82 d150 and I took it to my grandfather’s garage. All of a sudden my grandfather, a dyed in the wool gm guy, lit up lite a pinball machine. We rebuilt that 225 and it’s still running today.

[@marks8052]

awesome

[@davideidsvaag8785]

I drove to a farm in WI where the owner bought and sold tractors. He had a great little Farmall that had slant six! I think it was a farmer mechanic 1 off. Very cool. Love that Sexy Suzy Slant Six!

[@JrGoonior]

I consider the Slant 6 to be a bread and butter engine, it's reliable and it will get you where you want to go without hassle or fuss and will run FOREVER!

The modern day version is the 4.0 Jeep engine.

@@0004612 back in '87 a friend's mom got a new Cherokee, we took it out and did tons of smokies. Wow it was a torque pig. Darned too , if it didn't toast some mid 70s smog corvette while out cruising around one night. Even in one of those crappy vettes, imagine getting smoked by a 4 door box with woodgrain? 😂

[@johnwayne7715]

@@MrTheHillfolk I remember my 85 Caprice 305 getting smoked at our local cruise spot, by a Cherokee 4.0 HO version with a manual trans, it was quite a surprise! Not that my 305 Caprice was fast just did not expect the straight six could beat it. I think the manual trans and the fact it had the 4.0 HO badge on the back of the lift gate that I was seeing as he was pulling on me lol!

[@johnwayne7715]

@@0004612 yes I do believe all the american straight six's were reliable, including the slant. The Hornet was my first car, and I beat the crap out of it! The trans and flexplate were it's weak points, not to mention the body rust. An old junk yard owner told me the AMC six would run forever! Just don't run it out of oil! Thanks for the reply! I was thinking you thought the jeep engine was the slant! My bad! And I was wrong there were also a 232 six AMC and even smaller 199 earlier version. After my comment, I opened an old Chilton's manual 66-73 American cars that my dad had, I had forgotten about cube sizes the 77 Hornet I had was The 258 2barrel! I definitely miss it now! Fun times cruising the old blue Hornet! Surprised many cars at the stop light grandprix lol!

Funny you should mention the Mopar performance guide. It's hilarious when assclowns like Brian cabral says uncle tony is full of it and an idiot.

I think that if you play with old school stuff, you should for the most part, be doing it fairly budget oriented, still doing it right, just don't be spending hundreds and this and that when people know exactly how to make these things just scream.

Then getting some nice brakes for it. People dont think outside the box is the main issue

A lot of early mustangs were 6’s , very few were 289HO. They were light cars, till the heavy engines were stuffed in the engine bay and frames were reenforced due to the extra torque and handling capacity needed.

Tony, check out Aussiespeed (Slant 6 section).....they make a 3 into 1 cast exhaust manifold for the slant, one for the front 3 and one for the back 3....Doug Dutra created them and Aussiespeed now makes them. They have headers and intake manifolds as well.

[@silkysixx]

I have these and can attest to their quality and workmanship. As he said in the video, though, they don't have the runner length. They can breathe, but the paradox with many slant speed parts is that accommodating high-rpm flow is not really going to get you gains in the engine's meat-and-potatoes rpm range, which is 3000-4500. At that speed, it's all about length and scavenging, so long-tube headers and a long-ram intake are the ticket. I hope that an Aussiespeed Hurricane manifold and some headers make it onto this car.

[@DonalvonGriffyn]

This build is gonna be really cool. I say this as the owner of both a Miata and a Super Six.

I just want to add, I also fell in love with the slant 6; it was based on the 67 Coronet I drove; that engine had a PERSONALITY, and in addition to feeling great, and being reliable, economical and easy to work on, remains one of my favorite sounding motors.

[@modelnutty6503]

almost 50 years ago a buddy had a little old 2 door Valiant ('62?) was a great reliable little car that'd take some abuse. took a bit to get there but it'd pin the speedometer anyway.

[@unclemikeb]

I really appreciate your videos, lots of great info, many thanks. I owe a lot to that sweet running engine. I owned several beginning in 1970. WI winters are hard on cars, crap rusts until a car can be a total mess and just too hard to save. Between a Valiant, a Dart, and a Duster a slant six carried me to work and back for most of the 36 years I worked at the Belvidere, IL Chrysler factory. It started in winter and summer. In the 70's we had a couple winters where it was minus 10 degrees in the day time. Leave work at 3pm and all the cars were cold and stiff. Many times my rusty Duster went around jumpstarting newer cars, LOL. I put the biggest battery that would fit in that Duster, had to manufacture bigger hold downs for it. bought it at farm implement store. At ten below, it would grind, shudder, make scary noises, and then the power steering pump would howl as it spun up, but it ALWAYS started! There would be several hoods up needing jump so I would make the rounds. Two guys left the new car at home and started driving an older car with a slant six because they knew it would start. Got to love that. LOL. At one time I bought a used 1964 Valiant two door hardtop that had bucket seats and a four speed from the factory! The guy was wanting a new car with auto trans so he posted it for sale and I bought it. That was a fun car. It had a 3:23 rear axle so with the four speed trans first gear was quite low. If I pushed it hard it would lunge pretty strong off the line, had to be ready to shift quick because it would redline the engine at about 25mph. That shifter was tight and I never missed a gear with it. I never really souped it up, just tinkered with richer jets and timing. One thing that really helped was over sized exhaust and a Hush Thrush muffler. When the pipes rotted I had a local shop make me all new pipes 2 &1/2 inch diameter. In time it got so rusty I was reluctant to drive it. I listed it for sale with a slant six club and a guy came with a trailer. He had a mint condition Valiant wagon. he needed an engine and wanted that four speed and bucket seats to create the wagon Chrysler should have built. I lost track of that guy, hope he made it happen. I knew Chrysler introduced the super six because I test drove one in an Aspen. It was nice car. It also had a four speed trans., fourth was supposedly overdrive. Not sure why I didn't buy it. I think that was about the time I got a steal on the Duster. We had a full sized Dodge van the wife liked because she could see everything from up high. With sure grip and good tires it was actually pretty good in the snow.

[@stevenrhoat2902]

Built a 225 super six for circle track racing back about 15 years ago. Bigger cam with offset degree ported head and big Rochester carb. Wow! Torque was unbelievable till 5 grand!!! Didn't turn it over that. Destroyed any other 6 cylinder out of the turns! That thing would roast the tires to 45 mph! Ah but we move on, great idea Tony can't wait to see this finished!

[@bewilderment9268]

The first, and still the only, upgrades on my 63 Dart GT CV are the Dutra Duals, Super Six intake and MOPAR PERFORMANCE ignition. I use a Carter BBD straight off a 318. The air cleaner base is from a 67 Belvedere, which lends itself nicely to using an intake tube from an old Kcar. This runs to the round hole in the core support and bingo, fresh air.

[@davenhla]

My Grandpa had a 72(maybe 73) Avacado green with a dark green top Duster with a slant and a manual on the floor. Very basic car, nothing to it really. He loved that car, and to me it always said a lot, the man was a regional service technician in the 60's and early 70's and drove all kinds of big cars with huge V8's, but this smaller slant powered tin box with a stick shift was the one he kept in the hay loft and drove around here and there every summer with a grin into the 90's. I remember when I was 6 riding along down the back road and he taught my older brother how to drive a stick. We didn't tell Grandma :)

[@TheTrueVoiceOfReason]

@@davenhla That Dart was my grandpa's. He bought it brand new. When he passed, it went to my dad, and he gave it to me in the mid 80's. Did you know that if you don't change the oil for 4+ years and put LOTS of miles on it in that time, it is possible to kill a slant? Didn't even have it a week (was going to do oil change on Saturday) when it smoked the cam and 4 bearings on that Friday. I learned so much fixing and keeping that car on the road. I sure do miss it.

I had slant 6 225 (Super 6) in a 78 Dodge Aspen. I upgraded the ignition with short length 8mm wires, copper studed dist. cap, 50k coil, bosch plat. plugs etc. Also using a aftermarket carb (Fish). Surprised when got on the highway at 45 mph the car started making good power and wanted to 'GO'. What was crazy the engine made a 'Turbo Sound' which I didn't understand until years later when Tony mentioned the intake was engineered to have a turbo effect. Now it all makes sense!😄😄😄

[@jamesweis2671]

Years ago read about a slant 6 with a later model k car turbo. Since the 2.5l engine turned 6k rpm and 12 lbs boost, the slant would work and peak at 4k rpm. It was totally mechanical, reference boost to the fuel pump would increase pressure 1 to 1 until 16 psi boost so no need for complex controls, just an old school build with a lot of torque. Pretty much bolted upto exhaust manifold and ran output to box on the carburetor.

[@petershinkfield4980]

Bang on correct...the 225 slant ran so much better with a 2BBL. In Australia there was a HP 160hp version with hi comp, 2bbl and larger exhaust. These not only had 15 more horses they were way more economical. In 1970 the slant 6 was discontinued and the Hemi 6 was released...but that's another story

[@dennisyoung4631]

Reduced pumping losses, most likely…

[@PiDsPagePrototypes]

145hp single barrel 8.2:1 comp, R series through till VE, then both it and the 160hp 2bbl with 8.4:1 (though some math suggests the real ratios were 8.0:1 and 8.2:1), and then in the VF, the V7F spec "Pacer" with better then 190hp thanks to more compression, different cam, and different chamber design on the head. And all of them limited to a 3-speed manual.... With the Pacer's 1st gear being much higher then the regular 'box.

[@livesteamfan1]

I work with a guy that was a Chrysler engineer way back when. He said that they put a faster linkage on the single barrel and nobody could tell the performance difference between the two. He also said that once they were tasked with building a slant with 318 power, but slant economy. Some head work, a 2 barrel, and a street hemi grind cam, and they did it. Never went into production. They also toyed with a turbo slant, but couldn't get it to survive boost.

[@k5wxp22]

Love what you are doing here, Uncle Tony! This is old school hot rodding at it's best, only with a "modern" platform. Looking forward to seeing how this car performs.

[@aussiebloke609]

Fuel economy on old engines is a strange thing. I remember when I used to daily a stock 1098cc Mini...then I put twin carbs on and my mileage got significantly better. Turns out that having straight manifolds instead of all those bends means less pumping losses, as well as better throttle response.

[@mrdanforth3744]

You under rate the slant's performance potential. Look at it from the standpoint of 1960 when it was introduced. What was the competition? Ford had a 144 and 170 cu in Falcon six with very bad head design with the intake manifold as part of the head casting, very difficult to do anything with. Chevrolet had a 196 cu in six in the Chevy II (debuted 1961) that also had a very bad head design with siamesed intake ports with big post like head bolts in them. Studebaker and Rambler had long stroke adaptations of their old flathead sixes with OHV heads adapted that were poor for performance. Then there was the Corvair flat six with intakes cast into the heads, and very small valves. The very strong AMC six did not come out for another 5 years. Among that group the slant had a very good head design with separate intake and exhaust ports for each cylinder, good size valves and smooth flowing intake. The basic design was so good they could increase HP nearly 50% from 101 to 148, with a few bolt on goodies. The Hyperpak kit. Valiant proves the point in NASCAR's compact car race series where they went against the best compacts including some European models and wiped the floor with them until NASCAR cancelled the series after 3 or 4 races. It may not look like much today but there has been some progress in engine design over the last 60 years.

My Dad was a Chrysler dealer mechanic from 72 till 97 and has the Slant Sickness bad. He said the porous manifolds ran like crap and were replaced as soon as they were discovered, usually when being prepped for sale. He also said that a bunch of the warranty 2bbl intakes ended up on the pickups and grocery getters of dealer employees and were fixed by hosing them down with a heavy coat of VHT enamel with the car idling to suck paint into the pores where it dried and permanently solved the problem. The 2bbl was a popular upgrade in S. Texas where I grew up not just because the added horses, but because when the ac compressor kicked in while waiting at a light on the typical hot as balls day, a less than perfectly tuned/maintained Slant wouldn't stall and vapor lock and leave you to die

The Super Six upgrade is one of the best things I ever did with my 225 slant 6. I went from a Holley 1945 to the Super Six w/Carter BBD from an Volare. This completely woke the engine UP!! The Super Six on the Aspen and Volare was actually a package - 2 barrel carb, larger exhaust, and a slightly different rear axle ratio. In my experience, gas mileage was about the same with the 1 barrel vs 2 barrel setup. But power was MUCH better! As he said - why didn't Chrysler do this sooner?!

[@TAVOAu]

62 was the only year we had the reduction gear starter on the slant down in Oz, that was replaced by a locally made Bosch direct drive for the 63 model. We got the 2 barrel in late 67, using the BBD Carter on a cast iron manifold. it wasn't until 1970 with the Hemi, that we saw a dual outlet exhaust 'header' on the Pacer performance model. BTW, I'm totally a Hemi 6 guy, I know some stuff about slants, but the Hemi is my thing.

[@MrJayrock620]

For an auto cross application the Super Six is an awesome choice. Most people swap a V8 into these and they’re the ones spinning off through the cones or into the field. On a tight road course you need a linear power band and good low end torque and these have it.

[@GnarshredProductions]

I ran a chokeless 500cfm holley 2 barrel like what they use for circle track engines on my datsun 260z 2.6L engine it ran great and that was a straight six. For a performance setup I think the 350cfm might be too small. The slant could be pretty fast with a turbo you could use a cheap gt3582 or t3/t4 hybrid turbo from ebay and blow through a holley 2 barrel carb with a carb bonnet that would work well. I think with the slant not being a very high performance engine it needs some boost to wake it up. I heard what you said about the torqstorm supercharger but that is too expensive you could flux core weld a turbo kit together for a fraction of the cost using turbo bits off ebay like how us cheap import kids do it. Doesn't have to look pretty just has to work.

[@homevillegarage947]

I’m in Australia n I have a 350 Holley n runs sweet ! The slant is so much smoother with a dual barrel on em Love the channel mate

[@Zerinsakech]

I went from a since barrel to a 4 barrel Carb setup on my slant six. I got better fuel mileage from a Holley 390 than the little old single! LOL.

[@rockymeyers4030]

The Mercedes 300 SL has an inline six leaned over like the slant six, and it's a million dollar car

[@gorkzop]

Bmw's have a slanted six...mercedes not so sure

[@jeffreysciortino1988]

Something I’d love to hear you talk about re: slant 6. My 75 scamp with the 225, would stall if you floored it in a hard corner. Why did it have to do this? I read Lee Iacoccas autobiography, and he mentioned this (I think he cited the volare) as an indicator of how far Chrysler had fallen from the engineering juggernaut it had been through most of its history. This is a great build, staying true to the 170s original intent and incorporating into a modern, lightweight, low cg car. Can’t wait for the next installment.

[@ITS4390]

this really is going to be a cool build. only hot slant 6 I've ever seen in person was in a Willy's jeep flatrod, which was pretty unique.

[@jeffjankiewicz5100]

I had a 225 slant six in a 75 Duster and I beat it mercilessly, never left me stranded. Bulletproof.

[@johntaylor1310]

Love the new shop

[@scottinWV]

The slant 6 will run forever. Used to drive a Dodge full size delivery van in the early 90's. The spark plugs were seized into the heads and we were afraid to try to get them out. It didn't miss so I kept driving it. The owner of the company ended up selling it to a company just starting up and they put many more years on it. I'd like to own something that reliable again.

[@grumpycarlsworld]

I did hear you mention the "Australian marine" manifold, Tony. Not sure how aware you are of it, but we had a 2 barrel 225 available as the 160HP option in all Valiants from 1967 - 1969, until we switched to the "Hemi" 6 in 1970. Plenty of the factory cast iron 2 barrel manifolds available here. In 69, they upped the ante a little with the 175HP 225 "Pacer" version, by increasing the compression ratio, and let it exhale a little easier.

[@scottinWV]

You might have to turn the carb around backwards and loop that linkage cable around to it! ;) I can't wait to see this thing running!!!

[@silkysixx]

Man with that rear gear and a 3-spd manual, this thing would put a smile on your face. As for built 170s, I read something a long time ago about South American speedway racing - I think in Argentina - where the motor of choice was a 170 with long rods and a dangerously ported head that did absurd rpm. It's been done, just not by anyone who publishes!

[@APirateNamedJohn]

I just had a slant 6 rebuilt and bored over and put it in a 64 plymouth valiant on a rebuilt auto transmission and a mild cam with clifford 6=8 headers with a 350cfm 2 bbl holley and electronic ignition. I love the slant 6 its a fun little engine to drive

[@raybrensike42]

I look at that starter from under the hood and yes, there are a lot of things to like about a slant 6.

[@peterlake4400]

I had a 65 Polara with a 225. You're right about the performance. It would barely haul itself up over a good thick shadow on a sunny day from a standing start. Tough as whalebone , though. It got so low on oil once, the lifters started rallling. I put 4 quarts of oil in it to bring it up to the mark, and drove it for years. Had a mechanic offer me a high performance intake and exhaust for it - 6 single barrel carburetors and header exhaust. I didn't have any cash for that. One of life's regrets. Have not been able to find anything about that setup on the internet.

[@bruceraykiewicz6274]

Very old(78) gear head here. A good spell ago, I owned TWO slant sixes. A '71' Dodge dart, bought used, and later a '78' Plymouth Volari wagon, also bought used. I drove each of those cars to over 300,000 miles. Neither engine ever needed any major work. The 71 had old style ignition, and the 78 had the reluxer electronic type distributer. Until recent rears, I never owned any cars that went that far with just normal TLC. Sorry for the long post.

[@michaelbotta3735]

Years ago I owned two dodge aspen, 1976 and a 1979 , The 1979 was the super six with the two barrel I would average close to 1000 miles a week of driving on it.Could not kill it had it for years

[@FeralPreacher]

Maximize the Minimum. Sounds like a challenge. Gonna be a fun ride. Thanks for sharing.

Coming from a Miata owner I’m looking forward to how this turns out.

[@coachm2075]

I had a 65 barracuda with a 235 slant six with a 2 barrel carb electronic ignition that I took out of a valiant that thing ran like new and was pretty quick. Miss that car my father sold it while I was in the army back in the late 80's

[@crazytrain7114]

I 've seen quite a few back in the day at New England dragway in the 70s and 80s. They can scoot and keep up with the small blocks

[@lindsaythomas2283]

I had a 68 Valiant with a slant 6 and torqueflight. I loved that little workhorse.

[@erwinnijs1]

Go all out with three dubbel barrel side draft carburettors, individual runners and velocity stacks and tune the runner length yourself for maximum hp. It will be awesome!

[@2000freefuel]

Tony, in place of cutting holes in the firewall, may I suggest the IH method, AKA just kiss the firewall with a sledgehammer a few times till the engine fits. (yes that was actually done in production when IH fitted diesel engines into their Scout models)

[@billjamison2877]

Tony. I also love the slant six. Back in 1970, I bought a '64 Dart GT with the Charger 225. The thing that was odd about this car was the 4:10 Posi rear that cam from the factory! You could easily smoke both tires with no problems at all. Did you ever hear of a Dart GT with the 4:10 gears from the factory??? I bought the car from some old Geezer that bought it new in '64 and couldn't drive any more because of his vision.

[@retro440]

OMG, I had 1978 (I think) Dodge Aspen 225 Super Six!! Tony, love ya, brother!!

[@alfov8]

In my country /6 where used for racing, they reach about 350 hp, at 8300 rpm, with a two barrel webber ida and limited to 9:1 static cr. Stock cars came with holley 2300 two barrel carbs.

[@71_sears97]

It is interesting seeing this example of the super six intake as I have a marine 225 intake and there is a notable difference and that is the carb flange is an open rectangle, it does not have the two holes. I also have a super six setup off of a late 70s Volare and thought it was a 79 but I think it's all iron, I could be remembering the car wrong though, I will have to take a look at my manifolds tomorrow...

[@ScottKenny1978]

My concern for performance was honestly weight and balance of the car. Miatas are very precisely balanced and that's what makes them so fun to throw around a track or mountain road. But if you can get an aluminum block, that should address about 100lbs of the weight penalty of a cast iron block slant compared to that 1.6L Mazda i4. Edit: and Uncle Tony? You *gotta* paint the slanted Miata Plum Crazy!!!

[@idolworkshop]

I ran a 318 BBD 2bbl on a Super-6 setup I had, and it ran *really* well. Since the heat element choke arm isn't in the same place as on the original S6 2bbl, you can pick up a new element setup from CarbsOnly out in Burbank, CA. I clipped the arm on it a bit and bent it to fit, and it worked wonderfully. It never bogged or flooded. BTW, any updates on the Turbo Slant?

[@philliplopez8745]

Back in the 1970s I operated a ski lift equiped with an industrial 225 back up motor it was something to see it run another lift had an industrial 352 FE ford .

[@DeanMk1]

Uncle Tony is building (built?), what is known as a, Front Mid-Engine car, which is smart for what he wants to do with it, because it creates excellent balance. That car is going to be super nimble with a ton of punch coming out of the corners.

[@danielclover6992]

Back in the 90s I had a 65 dart 2 door with a bad 170. I found a slant 225 that said super six on the air cleaner. Chilton manual said it was a solid lifter cam. When I adjusted the rockers that thing woke right up. I can't remember what year that motor was. 0 to 100 it was a beast.

[@chiefbobdavis99]

Cool cool cool! Can’t wait to see this completed!

[@franciscodelvecchio2203]

excellent video, in agentina the slant six 225 produced 174 hp with a two-barrel carburetor in the Dodge Polara RT "Argentine invention" and in the Valiant 3 and 4 gt "also an Argentine invention" produced 180 hp with two one-barrel carburettors , although in turismo carretera "the highest Argentine racing category" the slant six 225 with a two-barrel carburetor but modified exceeded 250 hp

[@kenhale358]

I had a 170 in a 62 v-200 for 300,000 miles. So I consider my self an authority. I am a various aggressive driver. Loved that old frog. I used to pull my catamaran to the lake with it. Great power and good mileage. Of course there were mods preformed. Heads milled 100ths, larger intakes and exhaust valves, notched valves for chevy valve spring keeers because of inceasing spring pressure. Cam went to howard regrind m-4f 276in 276ex 410 total lift. Lots of valve lash noise, oh well! Adjusted them at same gap int-exh which i believe was(cant remember) it was way open from stock settings.Get rid or that factory broom handle. Ran a 60's aluminum intake that was modified for the bbd, split exhaust to larger tailpipes with "X" to quiet some noise, still sounded like a Baja buggy but a lot faster. Oh, I forgot I had a Pontiac 4 cyl 9.5" clutch and mopar 4spd with small Dana 3rd member out of a 65 "S" package from the junkyard. Don't forget to beef up clutch torsion shaft, that clutch will breaker. The o ly mistake I made was I should have waited a couple of yrs and used a 198 ci. It is a much better starting point. We were experimenting in 1967. I owned that car for 25yrs and I miss it most. Today I would install Doug Dutra's exhaust manifolds. The unibody finally filled me and it was scrapped.

[@needmetal3221]

Wonderful video. Fathers would drive a 318 and buy their sons the slant 6. No bullshit that happened in my family. Slant was real popular in fleet sales too.

[@claytonchar9232]

My father bought a new 1962 Valiant with the 225 aluminum engine. The 3 on the tree wasn't the greatest for speed shifting so I installed a Hurst shifter. When the engine later failed due to a cracked cylinder sleeve, I replace the engine with a Chevy 283 V8 bored to 302. The 225 engine was a high-torque wonder. The acceleration from a standing stop would beat most of the heavier cars with larger engines.

[@dangilbertville2577]

I had a 4 door 1962 PLYMOUTH BELVEDERE with one option, backup lights. That means it had the 225 slant 6 and 3 speed manual on the column. Didn't even have a radio. That car never quit. It would start at -40. I inherited it in 1970 to go to college. It bent one pushrod, and still took me to the dealership, although poorly, to buy the new part. The only other problem I had was vapor locking when I stopped the engine in 100 degree heat. A friend wanted me to turbocharge it, but nobody knew anything about that here in Iowa ( I think he saw an article about doing that to a slant 6 in Hot Rod.). Anyway, after college and not being broke any more I installed the two piece Hooker Headers, radial tires, and left the one barrel Holley carb. Holy smokes Batman. Before. you put your life in your hands if you tried to pass a car on the highway. After, when you hit a certain RPM (I had no tach.) it ran like a bat out of hell and really pushed you back in the seat. Passing was now easy. I drove that car until the middle 80s. The neighbors made me get rid of it after I got a new vehicle and let it sit for several years. I jumped it from a good battery with a little gas down the carb and it started right up. 30 seconds of rough running and it settled down to an idle. One teenager with $100 and I never saw that car again. As an extra: The local cab company used slant 6 Dodges and ran the engines for 300,000 miles.
