Are you planning on staying with a hydraulic flat tappet cam? Any definitive performance goals? If the car has headers on it and it is indeed a cruiser that you're not going for all of the available performance, this cam has a nice sound and good low and mid range torque. It doesn't have a monumental amount of top end, but that doesn't sound like what your shooting for.
