Mechanical V8 CAT 3408 Dyno Run

In this week's video we put a rare Caterpillar 3408 mechanical V8 on the dyno. It's mostly stock with performance injectors, pump, and turbo.

[@maynardreed4036]

Beautiful truck!! Fantastic engine. I used to work at a Kenworth dealer and nearly all of us there would come around and look at one of these when it came in. For me, it was the 3408, either PC or DI or the 1693. Real powerhouses the old-fashioned way - brute strength!

[@raymcghee7911]

Awesome to see old school equipment. I have owned 4 trucks and had all the major engines. The Cat was the most powerful and expensive to work on the Cummins was decent but the most dependable and easiest on fuel was the 12.7 Detroit. Before you all get ur knickers in a twist remember That's my opinion yours of course will be different.

[@MrTheHillfolk]

Ray McGhee I’m just a wrench but I like the older 60 series. It gets no love. It’s fairly simple , has decent power and gets decent economy. It doesn’t kill any category , just performs well and that’s what’s needed for a workhorse. Done many a engine dyno pull with some guys from interstate mcbee as they were developing replacement injectors years ago. I forgot how many runs we did , but it was over about a 6mo period every few days, and probably 4-6 pulls each time they came. Heh those ol boys learned pretty good how to swap injectors, I think we got it down to about 45 mins with 3 guys.

[@maynardreed4036]

I also like the 12.7 Detroit 500 hp. Dead reliable pull good and easy on fuel. To bad they stopped making them.

[@beckywatt5048]

MrHillfolk Lifetime wrench here too , your description is exactly correct , been around them all , young and the old moth eaten stuff too worked on gensets w/v 71 series Detroit's, 1693 cats , all the old Cummins , even the ones w superchargers B's I think , compression releases also, but with the steel haulers and the graveltrains horsepower was/is king .But with the spreading out of the auto industry that isn't what it was years ago.

[@gm16v149]

I’ve been running my 3408 powered Kenworth for over 20 years and it hasn’t missed a beat except for 2 blown turbos in all that time. It’s putting out 550 HP @1900 RPM at the wheels, but I see yours is air to air aftercooled whereas mine is jacket water aftercooled as from the manufacturer. It pulls 11 axle A-Trains @ 174,000 lbs (79 tonnes) all over the Australian outback. One small mistake, you’re wrong about the bore and stroke being the same as a 3406. The 3408 has a shorter stroke but the same bore, although a lot of parts are the same. If it had the same stroke, the engine would be 19 liters, not 18. My engine’s never been out the frame, it’s had 3 in-frames and it’s done nearly 70,000 hours since 1980 when it was built. The secret is clean oil, properly dosed coolant, proper start up and shut down, and bearing rolls at the right intervals. Plus never let anyone else drive it.

[@lewiemcneely9143]

I've watched yours and it is SWEET! Nice rig and if it'll run upside down it'll run anywhere. Thanks, Mate!

[@AnonYmous-qg4ph]

The 3406 has a half inch longer stroke. Bore is the same at 5.4 inch.

[@hoost3056]

I was about to switch to your channel and check in on ya👍 Good to see you're still around!

[@ThePaulv12]

Are 3408s a bit fragile? We have a Sig Series 02 KW Cummins coming up on 1.45m kms that has the shit thrashed out of it by 5 different people (all of who would be struggling to drive a stick up a dogs arse btw) and its had about 5 clutches and 2 partial gearbox rebuilds. The whole truck is turning to shit but the motor has had 2 turbos but not so much as the head off it. It overheats too. We just leave it alone as much as possible in case it stops lol. I suppose comparing an inline 6 to a V8 is a bit unfair since V8s suffer secondary vibration that inline 6s don't. We have a few 3406 Cats but they don't have the poke on hills our Cummins engines do. Would i rather a Cummins over a 3408 for the type of work you do? Nah I'll take the 3408 (that's the mechanic in me. I like you can open them up and the cylinder bmehp is lower than a 6 as well as the hp being at 1900 as opposed to 2100 ;)

[@gm16v149]

ThePaulv12 I hardly think mine is fragile, just look at the hours it’s done and the weight it pulls in extreme heat. There’s still a few operating here in Australia with bigger loads than mine. As long as you do the bearing rolls, like any early 3400 series, and you don’t lug it below around 1400 rpm, the crankshaft will last. I’m a firm believer in oil sampling every oil change too.

[@chriskelley7513]

Well I been reading the comments and replies figured I would add one of my own back in the day I drove a 83 359 with a 3408 and a 6x4 it was at 1150 hp and 2400 foot pounds of torque if you were real conservative about how you drove you could get 4.2 out it but usually 3.5 mpg and it had 308 gears in it it was never late for anything but a fuel stop and was registered on paper in AZ at 165 mph it was so hot that at nighttime you could get the elbows to turn red pulling hills but it would bust and split a 4 speed auxiliary straight down the Center

Old school trucks are coming back (except in California where they've been outlawed by the climate change fanatics) At my first job in the 1970s & 80s we had some light duty Ford F7000s with the 3408s. Very reliable and generally trouble free. We averaged about 6 mpg on the road (5 in the mountains) At the time we still had some with 534 gas engines that got about 4 mpg. They were pigs.

[@ajidamarjati]

For those who wondering why that big 18 litres V8 engines with over 600 bhp have relatively low torque figure? In my educated guess, it is a legacy from the past. Cat offered 3408 at max 450 hp 1450/1460 ft.lb back in 80's, why so? Because clutch and transmission back then not as strong as today and simply cannot handle big amount of torque. 1450 ft.lb was a big number 30-40 years ago.

[@vthegoose]

God damn that’s a good looking truck! Ready to haul too!

[@chloehennessey6813]

That’s so awesome. The engine in my pickup dynoed at 1138 HP and 1285 Flbs of torque. But it eats fuel like mad! Two fuel pumps are needed when that tune is in.

[@tdashkevich]

Laiken Bellesario is that a gasoline engine? The horsepower and torque numbers are really close.

[@chloehennessey6813]

Anatoliy Dashkevich Yes it’s a gas engine. It’s a 454 LSX with twin turbos. Finally found a great tuner in Florida. Low boost in 1st gear. Maybe 7 pounds. 2nd gear 10-12 Pounds, 3rd gear 16 pounds and 4th gear it rips at 24 to 26 pounds of boost. It’s had 100+ dyno runs and 300+ passes at the strip.

Fuel is an issue today... I have no idea which old and new engines are the most fuel effiecient... Guess alle the elctronic injection and working together with the auto transmissions works for better fuel consumption. But all the emmisions after treatment works the other way... Just a thought and in no way an expert opiniun from me

[@Tchristman100]

The 3408 and 3412 stroke (6.0") is not the same as the 3406 stroke (6.5"). But the same piston bore of 5.4".

Plenty of parts are interchangeable though. I’m rebuilding a spare 3408 truck engine and a lot of part numbers are the same, except for heads, block and crank of course. Water pump and oil cooler are different too.

You can make it a b model 3408 by putting a b model crank and cam in it convert the fueling over to a b model cut c16 pistons in it c 18 connecting rods and a 3508 turbo and marine heads then you can put some real power to the ground

[@Tchristman100]

@@bryanwilson5011 And hope that offset crank won't break. Why don't you think that truck pullers use the 90 degree Mack V-8? Because it is nearly indestructable. Caterpillar 60 degree V-8 (from a shortened 3412) crankshaft is weak and cannot take much more than 800hp reliably. Why don't you think that Caterpillar doesn't make the 3408 anymore-in favor of the superior C18?

@@bryanwilson5011 Really sort of a moot point now since the only 3408 that Cat makes is the G model for natural gas with spark plugs putting out a measly 425hp maximum. They do still make the 3406C mechanical (like my 3406B jacket water aftercooled).

[@robertgodshall7512]

That was my dads truck there is a lot of stories behind that truck. Broke the chains on the dyno for us. So you know I’m real underneath the American flag sticker there is a ding and the pin striping on the bunk is not the same height one sides lower then the other. Dose it still have the 4 and a 6 twin sticks in it.

[@eliasheilman544]

No it is a 13 speed now.....

[@shortthrow50]

Cool story but it’s power didn’t break the chains lol. Must have been a weak link. 1700 foot pounds torque and 600 hp doesn’t equate to much in today’s standards with what goes on these dynos. It was powerful for its day but the worked over 6 cyl are putting out way over that in torque and you have trucks with worked over cats and Cummins putting down over 1200 hp on these dynos. So no, this 3408 didn’t brake those chains because of its power

Don't forget about the DEF fluid cost which could be as much as four cents per mile and then those DEF filters are like $1,500 so yeah.... I might hop on the spreadsheet and try and drill down more on this. But for me, hauling intermodal containers, I pretty much have to get 6 miles per gallon but I still use a pre EGR pre ELD tractor to do it.

Hit the Jakes on the dyno if you nasty 🔥

[@doodar21]

And electronic logs.

Pre 2000 are NO ELD.

I'd rather have a 2WS

and 4 mpg

[@brandoncherry1651]

uh how's that economical ??? 3 4 miles to gallon

[@leonpeaks8967]

Different times. When freight paid better an fuel was cheaper an you made money

Need the extra 2 cylinders to make some hp. Cat is poop. but loved the vid!

[@Closeoutracer]

Box stock 3406 550hp and 600hp Cats were making 2000ft lbs 20 years ago.. this 3408 is 70's tech. Cat is the Power King ... Poop??? ..Lol .... They will leave your ass on any High Hill. 800hp Marine 3406 is 2200 Ft lbs in stock config with zero tuning.

[@eliseferrari8510]

sweet engine pity its in a piece of shitbilt

[@Closeoutracer]

Really? lol Paccar makes nice equipment. And that engine is well past it's prime. 550hp and 600hp Cat's were making 2000 ft lbs of torque nearly 20 years ago.. this 3408 barely cracked 1700 ft lbs.

[@289hipo]

I daresay you would keep that "shtblt" if he gave it to you jackass

[@davefleming1117]

The sound of the 3408 is UNMATCHED!! I love the sound of straight pipe 3406 but the 8 is super sweet! Love the CATS

[@yazeed3881]

No EGR no DPF bullshit , good ol power

1.8 million miles......131 lot lizards, 14 different std's, and 36 dr.s in 23 different cities and 26 years later shes still purring

[@truckin3799]

Very awesome 😎 thanks for sharing with us 👍🏻👍🏻👍🏻 and they say a 3408 wouldn’t keep up with today’s trucks....this proved that wrong didn’t it

[@rrobins9857]

He said the the engine was fueled. Meaning they turned it up.

[@mrrangemaster]

@@rrobins9857 like most people do with the newer stuff

[@opaqueman5043]

Tesla. That is all.

[@118chosen9]

Nowadays they put out those kind of numbers with six cylinders not eight, plus considerably more torque and decent mpg not gpm like this hog. Don't get me wrong, it's cool as all get out, but not efficient.

[@kaulincurtis9665]

@@opaqueman5043 we're still pretty far from making capable electric semis. There's just no way to pack the range a massive tank of diesel does with current battery technology.

[@cindytepper8878]

That's J & J Transport's old truck. It's got a 4 way behind the main box. Jimmy took good care of those trucks. Their main business was hauling transformers

[@truckerkevthepaidtourist]

you can tell by the paint job striping...😊

[@blythkd9017]

AWESOME! Thanks for posting. Don't know what kind of mpg's this guy is getting but God bless him for keeping some old school iron like that big beast out on the road! If that ain't pure American muscle, I don't know what is. I think I'm still having heart palpitations after hearing her beautiful song on that dyno!

[@Colt-tf6xf]

Bly thkd the best way to get good mpg on the 3408 was lie about the miles or gallons.

[@texasbeast239]

Sounded like the trumpet part of the Jurassic Park T-rex .

[@chriskelley7513]

The truck is still running today and there is not an ISX or a c15 that wants anything to do with it. It will snack on those PDI tune C 15 6nz engines they would not even be a full meal for that old cat

[@MasterWitchDoctor]

these engines were used in shrimp boats, tugs, and large lobster boats and it was very common to see them rated at 1000 + hp continuous hp, shaft hp in the 1100 range.

[@egodeathplease]

Very cool. Nice truck. I suspect that long after our government craps out these trucks will still be moving up n down the roads bringing people what they need😁.

[@otintc]

Would be nice to know what fuel mileage he is getting. I had friends back in the day that ran 3408s at the best got about 4 miles to the gallon

[@Second.Nature.Lawn.Michigan]

That's about average I think. 5 at best.

[@donnebes9421]

Second Nature Lawn Care 3.5

[@timwinemiller8615]

4 was a good number you could turn them to 400 horsepower on both sides and still do 4 mpg engine brakes were the reason they dropped it in us. Was still available in Canada after 87

[@xbesteverx1]

Man it runs so clean and sounds so good!

[@aaronbays4]

My grandpa was a diesel mechanic on the 3rd shift back the day, worked for Mason/Dixon trucking out of Kingsport. Anyways one of his jobs was running the trucks on the roller dyno like this. Said he always had the driver's door open when he did these pulls, so he could hear the engine/driveline better and it was really hot back in that room as well. I'll never forget him talking about nodding off for just a second while he was doing a pull, getting the truck up to speed on the rollers. Said he woke up, engine was roaring, there was a brick wall about 10' in front of him, he jumped right out the open driver's door. Scared him to death lol.

[@boomerang379]

I think this is the only 379 I’ve seen with a 3408.

[@thecurtray]

nope there is more

[@boomerang379]

Curt Ray no doubt there are more. This is the only one I’ve seen.

[@MrBigR928]

And it's a glider? Maaaan that is niiiice, real niiiice!👍

[@1topfueldrag]

I had a “real” one not a glider with a 5x4 trans

[@truckerkevthepaidtourist]

that's a glider it was put together and put why it's a 1990 mid Pete with a 1983 V8 cat

[@xXTECHxKNIGHTXx]

Amazing rig! My father's Pete has around 1.6 on it. :D. Love the video sounds like it's got another million miles left or more in it!

[@1693caterpillar]

Remember the 3408 Caterpillar along with the KT 450 and KTA 525-600 Cummins. Big power in those days.

[@justinlopez4806]

1693caterpillar still big power in miss my old 425 it was putting about 575 to the ground

[@1693caterpillar]

@@justinlopez4806 Now that's a real ground pounder.

I haul logs out of Louisiana we’re always over not very many trucks around could have kept up with her unfortunately we got rid of her because body was falling apart it was all there though
