I am looking for opinions on what 10.5 clutch to use in my 4 spd. 72 Demon that I am building. I will be running a 340 (w/ aprox. 400-450 hp) and 3.91 gears in the rear. It will be a street/strip car. I want something that will have a pretty firm pedal, I really hate cars that have a real soft easy pressing pedal, that takes no effort at all. Its a muscle car not a honda civic. LOL. My dad always ran ZOOM clutches in his cars back in the 70's with excellent results. What do you guys reccomend?
