what does a ground cam mean??

 

camshaft

 

the ground part really means nothing. a cam is a cam, but they make different "grinds." for instand the stock piece in an 01 Z is 198/198 with a .495 lift??? not sure on that one, but thats the "grind" i bought a Lunati 224/224 on a 112lsa. i havent put it in yet, waiting to do the whole motor, but theyre really nice cams. nitrous friendly as well.
