Memphis, TN – COMP Cams® is expanding the Hustler™ Camshaft Series for CT525 LS-based crate engine owners not afraid to push the limits of the rulebook for extra horsepower, torque and usable RPM range.

The Hustler™ profiles are now available in two stages for the CT525 crate engine. The Stage 1 Hustler™ cam profile offers .004” more lift than the stock cams and a very slight duration increase, making it very difficult to catch without removing the camshaft. The optimized cam profile and ramps provide for more area under the curve, resulting in greater power. 

The Stage 2 Hustler™ design presses the rules even further by offering the same .004” increase in lift but 15° more duration, surpassing GM’s maximum duration limit but maintaining the max allowable “legal” lift. In spite of this aggressive profile, the Stage 2 cam still maintains the “stock” like exhaust note, helping to not give away your new-found edge.
