Engine swaps are common, many of these cars came with inline 6 cylinder and small V8 engines. While these engines can be good performers, many times a larger or modified V8 engine is used to replace the original powerplant. |

Cadillac used a different motor mount set up, but even it could be used if the motor mounts were fabricated or bought from the aftermarket. All the V8s from the other makes (Buick, Olds, Pontiac, and Chevrolet) will exchange among the different makes. This opens up a LOT of combinations of body-to-engine swaps that can be done. |

A lot of this opinion is brought about by the perception that every car nowadays seems to have a [http://www.crankshaftcoalition.com/wiki/Why_not_to_use_a_small-block_Chevy_engine Chevy engine] under the hood. And while Chevy engines are fine performers, to many they lack that certain "something" when installed in a make other than Chevrolet. |
Take the 1967 Pontiac GTO as an example. Even though any of the GM V8s will fit, there are those who would say even using a 389 would not be correct, because 1966 was the last year of the 389. The motor that was originally installed in the 1967 GTO would have been a Pontiac 400. Pontiac V8s from 1955-'64 would also fit- and would also be incorrect to a purist. | Take the 1967 Pontiac GTO as an example.
