For racers wanting to push the rules, nosey tech officials, who will likely be able to spot a rule breaking camshaft just by sound alone, can be a real pain. Raised suspicions can lead to tech officials tearing through your engine, scrutinizing over the exact specs of every little part. COMP Cams® Hustler™ Camshafts for GM 603/604 Crate Engines sound as close to factory as possible, as to not tip anyone off that you may be bending the rules.
Although the billet camshafts are recommended for tracks that would usually not be removing the camshaft due to the COMP Cams® markings, COMP Cams® can regrind your factory camshaft. Stage 1 increases duration with faster ramps without increasing lift, while stage 2 increases lift to the maximum allowable tolerance.
