Ok I made a post a couple of days ago and didn't get much of a response. So I got ahold of the shop that built the heads here's what he said......... Seat pressure is 115# , open pressure is 310# , lift should be good to .570. I asked him what he thought about me running nitrous and turning it to 6500 RPM's (maybe 6700 not sure yet) and he said it should be fine. I just don't know if he really cares, he got my money last year. Here is the previous thread http://web.camaross.com/forums/showthread.php?t=371104 . For those who don't look at the thread they are P.E.P. springs kit # psk 574. Any help would be greatly appreciated!

 

Ok, little more information. I just got off the phone with a PEP rep and he said PSK 574 kit was good for 600 lift and seat pressure was 110 @ 1 800. I'm not a spring expert so could anyone help tell me what a little of this means? Thanks.

 

Call up comp (im assuming you have the cam in your sig) and give them the specs of the springs and see if they are ok.

 

I just got off the phone with a comp rep and he said that the cc306 needs about 120 seat pressure. The only other thing he could tell me was how bad the cc306 sucked! And how bad I needed a hypertech to program my car . Also I need 300# of open pressure.

 

I later called PEP back and gave them my cam specs and he said it should work fine. But if I wanted better ones he suggested some of there other ones that he likes for LS1's. He said the springs would work but I'd have to use diffrent locks and retainers. I'm lost, I may just look for some 918's and be done with it. I've spent to much money to ruin it all over something this cheap.
