Re: Shark racing hi-perf cams.
If it is a regrind, the base circle of the cam has probably been reduced enough that the hydraulic lash on the lifters probably cannot adjust to them. Personally, I stay away from Regrinds, they are hard on your valve train due to the steeper ramps caused by the smaller base cicrle and they tend not to be as "hard" as either the original cams or those done up from black billets.
