on your setup you will prob go down to 4-6psi on stock pulley. 3.2 would put you down at 9-12 easily -- Better think about cam, rockers, or IC

Thats what i was thinking! I was gonna use the ZZP VS Cam and maybe some 1.7 ratio rockers...
 


Sweet. I wasnt sure if i could even use rockers with my cam, since i thought the rockers did the same thing as the cam... I also have a set of LS3 yellow behive valve springs from my buddys 2010 camaro that according to zzp would help too.
 
Ok... well the yellow LS3 springs are rated at max .570 lift, and the vs can with the 1.6rockers is rated at max .507. So i think the rockers with that cam, plus those springs should be a nice combo....
 
Make sure you take into account if the valve guides have been milled down to accept more lift. I'm pretty sure unmilled guides won't allow .570"
 


dont waste your money on the 1.7s for a 7 whp gain. that's a lot of money to dump on some rollers for that. if you want to go higher lift just start with a bigger cam.
 
Yeah. I think what I may do is just run the VS cam with some other mods and call it a day... I dont wanna get too radical and possably compromise the drivability of the car so... I think I am just gonna run the VS with my LS3 springs and retainers and call it a day. :-)
