Welcome Groundhog. What engine are you going to use and how are you going to use the car. If you race it or are just going to drive it you might want to think about the gears. Also what transmission are you going to use. I had a 418 stroker in mine and raced it with 3:27 gears, but on the highway with a 5 speed I hardly ever used the 5th gear. The Coupe that I have now, if I ever get it back has 3:56 gears and they are about perfect for me as I don't race any more.
