I've got a '68 428-4 in my '68 GTO. It's hooked up to a M-20 Muncie. My clutch just won't hold the torgue anymore. It's close to 450 HP with the work that's been done. I won't be building it up anymore. I don't mind spending more to get the best. The car is used around town, but I like to get on it when I'm driving.
