if you have the time and money, you could call crower cams and have them make you a custom grind cam, and even make you a crank rods and pistons and such... if they already know the specs on the motor they can do it right there, if not you'd have to get your motor brought to them and they'll engineer you something specifically to your desire.... thats the one thing i love about crower over most bigger cam companies, specially since they're right down the street from me
