Heads ported to 240cfm. Intake home ported a little by my son. Cam is HR 230/236 .510/.521. Has 1.65 rockers now. So more like .550/.570. 112 lsa Sent from my iPad using Tapatalk |

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.
