The Stealthy Stroker Rectangle Port camshaft is designed for street performance in cars using 402-418 cubic inch LS engines equipped with rectangular port, LS3/L99/L92 style heads. The Stealthy Stroker will have a slight performance idle and very good power throughout the RPM range from idle to redline. This camshaft is designed for the enthusiast who wants the extra performance associated with larger displacement engines while maintaining excellent drive-ability and street manners. While this camshaft will not require intake or exhaust modifications, substantial power increases can be realized when used with headers, high flow exhaust, intake system upgrades, increased stall speed torque converter and increased rear axle ratios.
The Stealthy Stroker series cams are designed with our renowned smooth cam lobe design that provides quiet valve train operation and excellent upper rpm stability. Cam Motion offers this cam in 5150, 8660 and our top of the line 8620 camshaft cores.
