This camshaft is very aggressive and should only be used on maximum effort combinations. This cam has made 600+ RWHP in a few setups, but attention to detail must be paid to attain those results. It has a very aggressive idle, and makes great top end power at the sacrifice of some low end torque. Cam specs are 247/258 112+3 and comes a 3 bolt timing gear pattern. Our .660" Lift Platinum spring kit with titanium retainers work great with this camshaft.
