that 572 is going to crack that muncie like an egg. i hear stock muncie rock crushers are rated at 375 foot lbs...which is like a nice 350 without aluminum heads. big torque requires an expensive clutch and standard transmission. a turbo 400 is a safer bet...all i know is that torque breaks stuff and torquey shock loads break stuff quicker.
