340 Roller Cam/Lifter Issues.

I would take a better look at that cam, see all the little pits in it? Thats not what our cams look like,they are perfectly smooth and nicely polished. Those pits are from a cast core not a billet core...yet more proof of COMP being ****. Our cams are ground on billet cores from Racer Brown, if you ask Jim to grind on cast core he will tell you to go call comp for **** like that! Toss that POS and get a real cam....sorry dude, it sucks bad but that cam is junk. I will post a pic tomorrow of a "real" cam. BTW Lunati and most of the "big" guys use cast cores. If Scummit sells it, its probably cast....go with the small guys and you will get a much better profile anyway, all the big guys use antique profiles designed around SB chebbys not Mopar. Call Jim at 410-866-7660 Racer Brown Camshaft Engineering and probably THE best mopar grinder in the US. He doesnt answer phone until at least 1 pm EST.
