This is my build of my Chevy Turbo inline six. This build started out as a very basic just trying to add a turbo and keep stock components on the six. In the end it turned into a all out build with the absolute best parts I could find. Total horsepower numbers have not been determined yet.
The car itself is a 1967 4 door with a Smith race craft front clip, TCI torque arm suspension, 4 wheel Wilwood disc brakes.
