Thanks to its popularity, the 4-4-2 was now its own standalone model as opposed to a trim level for the Cutlass. Initially offered with a 400 cubic inch engine claiming 350 horsepower, GM took the gloves off for 1970, allowing Oldsmobile to stuff in its 455 cubic inch big block between the A-body's frame rails. If you believe that there is a replacement for displacement, our LS swap systems might be right up your alley.

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.
