I want to restore my dads car as surprise for him, its an 81 and i'm from Egypt, its hard here to find the same stock engine, i need to know other GM models that their engine will fit

 

What engine is in it now? I believe, but am not sure that it could be an Olds 350 gas, Olds diesel, or Buick engine. This is the vintage that GM was mixing engines from different lines. John

 

Welcome to the site, a worthy endeavor.

 

Thanks Old & john i don't know the number of the engine i know it's v6 and they call it the blue engine , the american cars here are known as the caprice, skylark, and caddies known as brand that's it, they know nothing about oldsmobil so i have to fit what i got around , i dont know where to start and i want to get a v8 is that posible .

 

There was a diesel V6 in that vintage, but they are not very common. If its a gas engine then it sounds like the Buick 231 V6 engine. I believe the easiest engine to swap in would be a Buick 350 or 455 engine. I say that because I suspect the starter, wiring harness, motor mounts, etc. would match up with another Buick engine but need to be changed or modified to put an Olds, Pontiac, Cadillac or Chevy motor in the car. Hopefully other members more familiar with Buick motors can add their thoughts to this thread.
