Anybody try this cam?
I found this on GM parts direct. It is listed as a C5R Road Race cam. http://www.gmpartsdirect.com/results...umber=88958606

Ummm to make it in simple terms -- that cam is HUGGEEE
251/239 .570/.570 is enormous. The new Thunder Racing T-Rex cam is a 242 if that puts it in perspective. I dont think you could use that cam in any normal streetable applications, your idle is going to be horrible, and its going to lope like an old school 502ci.

239*/251*, 106, .570"- Not a C5R cam. It's the Grand Am cam developed for World Challenge Cup cars. Does require notched pistons. I have it. Idles well at 1200 rpm. No numbers yet. I posted a sound/video clip, awhile back, of it at idle. FWIW.
