Sportsman Tool Steel Cams For GM GEN V (LT1/L83/L86) Applications

compcams_logoCOMP Cams® tool steel cam core technology, widely seen in NASCAR, NHRA and other professional race engines, is now available for GM Gen V (LT1/L83/L86) applications. Tool steel is 30 percent stronger than the SAE 5150 or SAE 8620 cam cores typically used for LS camshafts. It allows the use of more aggressive profiles on both the direct injection (DI) fuel pump lobe and the cam lobes. The size and shape of the DI lobe is customizable to support more horsepower over the OEM design (see fuel pump lobe options below). The polygonal designs are available with three, four or five “throws” per revolution. The four-lobe option can be advanced or retarded to properly phase with the injector timing to maximize flow, reduce pressure fluctuations and minimize fuel bypass.

Comp-CamCOMP Cams® tool steel cam cores are through-hardened, meaning that engine builders can choose virtually any combination of duration, lift, lobe separation and advance. They are superior to the traditional hardened surface of either induction-hardened or carburized steel cam cores. GM Gen V (LT1/L83/L86) Sportsman Tool Steel Camshafts are available with or without Active Fuel Management (AFM). Call for assistance in selecting the right tool steel cam for your application. Like with any VVT application, custom tuning is required.
