GPI CamShaft 228-380/GPX240-375/112+4

This is our most popular street / race cam, and for good reason. This is the perfect cam for the hardcore street / strip enthusiast, and makes more torque and horsepower than our SS1 and SS2 cams. Very strong to 6900 RPM. Track tested, developed,and proven! This cam loves 3.91 gearing.

This hardening process creates more durable wear surfaces on the lobes while maintaining the desirable ductility characteristics of the 8620 alloy. The final product is a camshaft that is stronger with a more durable wear surface. Our 8620 cams are a superior product.
