Hi really wanting to upgrade my cam while getting motor rebuilt and not sure which to go with. Colt stage 4 or hamilton 188/220. Any input is appreciated, thanks
It depends on what you want to do with the motor and where you need to move the usable RPM range. We all can recommend anything but until folks better than me know what turbo or turbo's you have, gearing, Transmission, and tire size you can't really give a good recommendation.
