Oldsmobile got its own X-Body variant in 1973, dubbed the Omega. It shared mechanicals with the Chevy Nova, but had Oldsmobile's signature waterfall grille design and could be optioned with a Rocket 350 cubic inch V8. Today, you can option yours with a Gen III/IV LS engine thanks to our bolt-in swap systems.

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.
