I picked up some PI heads and intake. Now the question is should I go with aftermarket cams or not? If yes, do I go with Comp Stage 2 or blower cams? The heads already have Trickflow springs and seals rated to .600... Here's a picture:[img width=800 height=450]http://i129.photobucket.com/albums/p235/MustangTeen98GT/Mobile%20Uploads/2014080295192820.jpg[/img] I may go boosted but it'd be on stock block until issues arise, I currently have 4.10's. I'm looking for high 12's which I'm thinking will be possible with a Comp Cam but boost (more $$$) would put me in the mid to low 12's but then I feel like I'm pushing the limit on the stock block. Any feedback is appreciated.
