    What Engine For My 81 Trans Am

    I am currently looking at some Blueprint engines. I was considering the 383, however, I am now looking into a 400/406 or 4 cylinder Cummins. As I want to retain the Turbo usage and make a healthy 500 to 600 hp. https://blueprintengines.com/collections/jm-small-blocks
