The Legend of GM's MASSIVE 11.5L V12 Engine 

The History of the Ford E-Series Econoline Vans & Cutaway chassis also Isuzu 7.8 Duramax I would like to see those vids

Talk about the 22L V12 diesel used in the Soviet Кировец К-701

Hi Is the 2016 Toyota Highlander 3.5 fe engine the same as the 2010 Toyota Venza 3.5 engine?? Thank you

Have you ever heard of Smokey Yunick's Adiabatic Engines? They were developed after his foray into hypertuning the 2.4 series Iron motors. Yin/Yang Pistons and combustion chambers. Great output. Then developed his own line of motors called Adiabatic. Meaning the exhaust temperature was close to intake temperatures. You could place your hand on the exhaust pipe at full power without leaving flesh. There was a turbo, the intake was inside the exhaust, and the air charge temperature at the valve 400deg f. He put a V2 (75 cu in) in the big 3's little cars. Escort, Chevette, K car, and I think VW was one too? The Chrysler guy drained the tank and put low grade fuel in and spent hours trying to get it to ping. Traffic leap from stop in 3rd gear. Grunt, grunt, gone! It produced 100 to 150 hp. A 225 cu in 3 cyl inline made over 260 HP and the V4 made 340hp and required no cooling system. Not air, not water, nothing. Amazing Man. The torque was impressive, and I realized they could replace semi truck motors, as the little motor RPM was high enough that a simple 2:1 RGB would adapt them readily. Omnifuel. No cooling system?

I would like to correct you on something. This series of engines does not have hydraulic lifters. Nice video though. Also a feature I don’t see anyone who talks about the v-6 version of these engines is that they have a separate journal on the crankshaft for each cylinder thus making it have a torque of a inline 6 cylinder engine in the v configuration. 🙏🙏👍💪

I think I may have found a replacement engine for my 1965 Chevrolet C20 with a straight 6-292 fleet side.

​@michaeladams If you can find one lol. I hear there's only estimated to be a few thousand of them left.

Was supposed to bring it back in the early 2000’s but never did. It was going in the caddy 16 ultra luxury car that never came.

Screaming Jimmy

I was an engineer on GM 16/92's for many years. Huge engine, big as a car. They had super chargers & turbos on them.

Is that the one in the Big Bud 747?

​@@noneshereyou know that with a turbo only the 2stroke detriots wouldnt run. 2 stroke detriots couldnt suck air n/a nor would run. So all ALL 2 stroke d had super chargers and they didnt add power at all. Without it they wouldnt run. But it was a old method for turbo/super charger combo. So anyone thinking its new. Its not.

I think anyone who has read about the Hall-Scott wishes we were around back then. Hall-Scott 1091 ci running on butane. in a fire truck, taking off, wide open, up a long steep hill going to a fire in the middle of the night, you could see 3 foot blue flames from the stacks said one guy on curbsideclassic 😊

It would be interesting to see how long the 700 would stand up behind the V-12.

A 700R4? Not good for this engine.

It makes a very low tone resonance that goes right through the walls of a house at 2 blocks away. 🙏🙏👍💪

@@craigwhittingslow9689 kinda like past GMC school bus w/ BBC 454.

Yes, the Buick straight 8!

The 478 was the biggest V6.The dump truck in my avatar picture has one.

GMC made 305, 351, and 478 V6's. I believe they were all called big block V6's

@@jonathanryan2915 There were three other V6's too. 379, 401 and 432 V6's. The 305, 351 and 401 came out in the 1960 models. The 478 came along for '62. The 379 was a 351 with a 478 crank and the 432 was a 401 with a 478 crank. Both of those were '73/'74 only. The V12 was used from '60 to '65. For the '66 models, the 637 V8 replaced the V12.

@@turbo8454 oh yeah, I forgot about the bigger ones

@@turbo8454 would love to see a video. Building up a 478 V6 for my 65 GMC pickup.

I literally found one today with all original parts but it’s been in shop for decades and by shop I mean some tin with dirt floor. Couldn’t see it because it was covered completley in Busch light cans

An interview with your grandpa would be really cool

@@firstlast--- Sadly, he passed 24 years ago, but I still have the manuals.

Fuel efficiency wasn't important for most of the intended applications at the time making your claim disingenuous. No argument about the timing difficulty though. These were well known for being inexpensive to purchase, uber reliable, with extreme driveability given their torque at under 1000RPM. If you had one of these in a vehicle that wasn't intended for heavy work then you had the wrong engine. This was not a garbage truck engine. Bad application.

The 637 shared the 478's stroke, at 3.86".

The GMC V6 were 305, 351, 401 and 478. The 305 was the optional engine for GMC pickups and suburbans. I think the 351 was offered in 1966 for pickup trucks. Many medium trucks up to 65000 pound gross combination weight used these engines . I think the last year they were offered in pickups was 1968. Around the early 70s two displacements of 379 and 432 were created and the earlier engines dropped. I think the last year for the GMC V6 was 1973.

Pierce guys also
