I have an 85 5.0L engine from that came out of a 84 crown vic wagon. Now the engine wasnt stock in the car and i have no idea what it is out of. The only inscriptions I can find are a 30, an HD and a K...I have no idea what kind of cam this is. I want to run one like a HO cam from a later model engine, and am wondering if this cam is a good base for a regrind.
