I already had the Cammer but needed a car to put it in. Bought a Mustang fastback but by the time you cut the shock towers, have headers made, install a rack and good front suspension, good brakes, etc, etc; it was starting to make less sense than the Cobra (except you get a roof). PatrickT has sound advice; I lowered compression a little and installed very streetable cams. You really need to determine what you want to do with the car. I've had plenty of hot rods in the past and dealing 7-800 naturally aspirated hp is a pain and not worth it IMO. As along as it runs good and is reliable - 4-500hp is alll you need if you're just going to street drive it.
