It is a 1971 GTX clone. 440 Stroked to 497 cubes, 727 auto with a reverse valve body, an 8" Coan converter, narrowed 8 3/4 rear with 4.10 gears and a Detroit locker and Moser axles, and has been back halved with 4 link and a 10 point roll bar. The GTX is letting me relive my younger years. The engine I have came with the car when I bought it. It is a 497 inch with your Edelbrock prepped heads and Victor intake, 1.6 rockers, HTL5660BS solid cam. It is a street car that sees a little track time.
