Camshafts

When we set out to design our bolt-in camshafts, the standard requirements we placed upon ourselves were to develop a camshaft that produced at least 100 ft-lbs of torque smoothly by 2500rpm and maintained stock idle and under throttle characteristics. All of our bolt-in camshafts work on a completely stock engine, however we recommend that new lifters be installed.

561-1 cams installed in a stock 103" with Drago's Dragula pipes, and a Heavy Breather air cleaner. Before and after ECU and dyno tuning.

To see the most out of the cam, it is recommended that you install a good, free flowing exhaust, air filter and an ECU tune. Give us a call or shoot us an email for recommendations or suggestions.

 

Stocked high performance grinds.

These camshafts require additional modifications such as different springs, different pistons, larger valves, etc. Call or email for more information.
