Ford's new Ecoboost V6 has all the stump pulling torque you need - and the fuel efficiency that puts a smirk on your face at the gas station.

Even if you end up disliking the motor, you still can say "That's not your ordinary 350 or 454 Chevy in there partner!"

If you're thinking BOP... the answer is Cadillac 500 ;-)

Hey Sport,

You are posting multiple threads asking about pontiac, Cadillac and Buick engines on a Chevy truck thread.

Figured I'd throw out another engine that doesn't belong in a 4X4 Chevy.

BOPC swaps in these trucks were once very popular, Just as....If not more than LS swap are today. An Ecoboost swap would be a lot more involved.

The Ford 3.5L Ecoboost is a offshoot of the Duratec POS with twin turbos & DI.

Have you ever performed a Ecoboost swap before.....Slick?

Why not just drop a 454 and call it a day...

Seriously??? Can you even begin to imagine all the electronic components you'd need, and a way to mount the intercoolers, not to mention a megabucks adapter for the trans? It would make an LS swap look like a walk in the park. And it's a FORD.

On the original topic, Cadillac 500 and Pontiac 455 engines probably have the best parts availability.

The Caddy or Olds would have awesome train like torque all day too.

[franken]

I'm more partial to Pontiacs after Chevy but that's not objective.
Is the th400 a BOP bolt pattern? If not you may need another case.
Did they make short crews in 77, least of all in 3/4 ton? Seems unlikely.

There is a reason the op is getting these type of responses. This is the 8th thread he started in the last 2 weeks about swapping a Pontiac, Olds, or Cadillac motor.

Olds 455 engines that were from Toronados were incredible engines. I believe they were equipped with bigger than normal lifters and had more nickel in the block. 425 Toronado engines (earlier; I beleive '66 and '67) were incredible as well. These engines were often coveted for marine and other heavy duty or performance applications.

To go along with all of this the Olds 455 was also the only engine mounted in the GMC motor Home. Basically a Toronado drivetrain.

I would go with the olds 455 out of all of those. It is very reliable, makes big power and gets decent mileage.

The buick motor seems on paper like it is made for trucks with 510 foot pounds of torque at like 2000 rpm but they had oil issues, the oil pump was more sensitive to wear than other brands. if you go buick I would change out the timing cover hopefully for a new one (the oil pump is in the timing cover). Also the distributor is in the front making it more vulnerable to water splashing than the others who put it in the back.

Pontiac engines make great power I have had several and have been happy with them.

[Titomars]

Interestingly enough is that it was the Pontiac V8 that was a truck engine for a time. They were used in GMC's in the later 50's. Buick 350's were used in Kaiser Jeeps in the late 60's.
Personally if I was to go with a BOP engine I would choose an Olds 455. Pontiac hard parts are getting scarce and Buick T/C covers are even worse because of the oil pump issue.

Just remember it cost more $ to go odd ball Bop than Chevy, now Fords need a good Chevy motor not F**d in a Chevy..

[nonstop]

Man up and go with a Detroit 4-53 or 6v71t! Are you looking for unique or longevity? This covers both!

[rcrahn]

I love Pontiacs, have a 1969 Firebird with a full roller 462....As others have said, Pontiacs like mine are just more expensive to build than a Chevy.

I looked at the OP. I would like to throw out another idea - why not an 8.1 L?
In that 77 Crewcab it would be a stump puller....

[rich weyand]

The Buicks had a lot of torque, but they would burn valves in sustained high load, like pulling a trailer in the mountains.

[hatzie]

472 Caddy. Stump pulling torque and the 500 is getting harder to find.
Quoting an acquaintance, that had one in a 77 3/4 ton GMC, about towing an Airstream Sovereign up the Grapevine. He said "It didn't feel like she was towing a thing. I just put my foot on the pedal and she picked up speed." That's a 6% grade folks.

I think all of these b-o-p-c swaps are neat, and I researched it myself. It's definitely possible, but the transmission options seemed limited, compared to a Chevy. Th400, no problem. Overdrive possible with a 200-4R, but I wanted stick, and that gets messy. For example, some of these engines don't have the crank drilled for a pilot bearing. Ya, it can be added, but that's a lot of work. I'm not in love with bellhousing adapter plates either. Stock bellhousings exist, but are likely tricky to find and are setup for a Muncie M20.

One thing that seemed clear is to find the one vendor that exists today that specialize in that particular engine. They all have one, and no doubt that outfit would be a fountain of knowledge and parts.

Other interesting tidbits; the Buick is 100 lbs less than the others, nearly the weight of a SBC. The caddy is light for it's displacement. The Pontiac blocks are all externally the same, so that might help with headers, etc. the pontiacs also had a long run, relative to the others (the engine design, not the 455 specifically). The Olds seems to be the torque king if we ignore the caddy. Some of the engines need oiling system modifications if you're going to rev the snot out of them, others don't. It's all quite interesting. I wish the General was still making all sorts of engine designs today, but it's understandable why they don't.
