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 V LT engine thanks to our bolt-in swap systems.
