Hi all, I have a 1978 GMC Sierra Classic pickup that came from the factory with the Olds 350 diesel engine and TH400 transmission. Somewhere along the line the diesel puked and it was replaced with an Oldsmobile 350 gas engine since all the block mounting points and bellhousing patterns are the same between the two.
I just bought the truck a few weeks ago and the 350 gas motor is tired and about to die, and I just need to keep this thing on the road a little longer.
The present transmission is in pretty decent shape it seems, and still shifts good. I know that the BOP bell-housing pattern is different than Chevy's , so I would have to stick to Buick/Olds/Pontiac engines. My question is, will any V8 work? The older 350 Oldsmobile engines are kind of hard to find around here, but the newer 307's from early 80's cars are pretty common. Would one of those work? How about Buick V8's?
Any input is appreciated.
