Forget the stealth stuff now. The CHP #10-th Thumper Cam will have an impressive sounding "Thump" at idle, about 800 RPM. This cam is designed to perform best with stock or mildly ported cylinder heads. The #10-th camshaft can be set up in either of two ratios; -.520 with stock rockers, or .535 with an CHP Shaft Rocker System. The lobes are specifically engineered for long term durability and is the ultimate Hydrolic Flat Tappet Camshaft for Direct Drive Airboat Applications.
