The Apollo was Buick's version of the GM X-Body. With an optional 350 cubic inch Buick small block, the Apollo packed a punch in a small package. Sharing running gear with the Chevy Nova, there are plenty of options if you want to take your Apollo to the next level.

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.
