Like all other GM A-Body vehicles, the Tempest received a fresh makeover in 1968. It also received a new 350 cubic inch engine to accompany its larger 400 cubic inch sibling. If those options aren't quite exciting enough, our bolt-in LS swap systems might be just what you're looking for.

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.
