The Stealthy Stroker Cathedral Port camshaft is designed for street performance in cars using 383 & 402-418 cubic inch LS engines equipped with cathedral port, LS1 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.
