The Street King "Single Plane" - Cathedral Port camshaft is designed for maximum street performance and street-strip application in cars using 5.7-6.2 liter LS engines equipped with cathedral port, LS1 style heads and single plane intake manifolds like the Victor, High Ram, Mid Ram and GMPP style intake manifolds. The Street King will have a very lopey to rough idle and explosive midrange and high RPM power. This camshaft is designed for the enthusiast who wants a very aggressive camshaft for maximum power from their street driven engine. This camshaft requires pistons with valve reliefs for proper piston-to-valve clearance. This camshaft requires intake and exhaust modifications for maximum flow. Headers, high flow exhaust, intake system upgrades, increased stall speed torque converter and increased rear axle ratios are required to achieve maximum performance.

The Street King cam is 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. You can read more about our cam cores here > Cam Motion's cam cores
