New cam
Got a new comp cam HR to replace the crower HFT I’ve been using. Engine guy questioned a couple of the rhoads vmax lifters,, nothing wiped but while we’re in there I don’t want any upcoming possible problems. Had Kauffman custom grind,, asked for their 236/242 cam but add 2 more degrees of exhaust duration for a 236/244 112 ls. On their site the 236 /242 cam has an advertised 290 but mine is 286 . Numbers wise I’m just a little bigger than the crower I’ve been using. Hopefully it works out good. 455 .040 over, 9.75-1, rare manifolds with their 3” headpipes. Stock , slightly reworked iron intake. TKX trans with 2.87 first gear and 3.31 rear. I use crower SS 1.60 enduro rockers.
Only 67 degrees of overlap?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
