The newly designed intake and exhaust lobes allow the CL-2 to run at higher RPMs before the engine goes into uncontrolled valve float. This is a great cam for any stock Chinese OHV class.The DynoCams CL-2 is legal for the current profile rules for stock classes.
The CL4 is specifically designed for the NKA rule package. With no minimum duration requirements, we were able to smooth the nose of the cam allowing it to rev well into the 7000 RPM range. The CL4 shows gains in the 6600 RPM range over our current CL3. This cam comes buffed, further smoothing the nose, to take max advantage of the 10.8 springs.

High performance economy grind providing significant power increase over stock cam.This is the result of many R&D hours testing what the big block engines like. Cams is cut on a close base circle to the stock cam so the compression release is still functional.246 Duration, .260" Lift using stock rocker arms (.250 at lobe), 110 LSAThis cam produces power from 1800-5000rpm and gives a drastic improvement throughout the entire RPM range. Recommended for Golf Carts, Mud Motors, Short Track Go-Karts, Marine and Pulling/Towing applications where a broad powerband is a needed and loss of low end is unacceptable.This cam is easy on the valvetrain and will not "beat up" your valves or lifters.
