1978 was the first year a V8 was not the standard engine for the Grand Prix as the car lost 600 lbs. in an effort to improve fuel efficiency. However, its G-Body platform is a solid base to build upon with numerous parts and compatibility with several different GM engines. If you want to drop a Gen III/IV engine in your Grand Prix, our LS swap systems can get it done.

From Ford Flathead to GM Gen V LT, and including everything in between like small-block and big-block Ford and Chevy, Gen III/IV LS, Coyote, Hemi, and more, we have the parts to coax more power out of the engine under the hood of your hot rod.
