My thought is that a stock C-4 will not stand up to a car running in the 10's. That much power (400-500 hp) will fry the clutches in a stock C-4. You will probably also be running a high (4000-4500) stall converter in a car like that. You'll need a built C-4 or C-6 for that application. Anyone disagree?
