GM's Cadillac, Pontiac, Oldsmobile and Buick divisions have made some of the worlds greatest V8 engines, and many have been installed into Jeeps. They can be made to fit in many Jeep models - the Buick V8 being chief among them. The Chevrolet V8 is vastly more popular. While these all can often use the same bellhousing-to-transmission adapters or GM standard transmission as the Chevy V8, they do not enjoy the wide parts interchangeability of the Chevy V8. Some have oil filters or starters in inconvenient locations. Other factors usually related to physical shape or size make these a greater problem for installation than the Chevy V8, but for the Jeep owner who understands and prefers these good engines, they can make a good swap.
