hey guys so for the past month I have been workin on the vette with my friends, and heres whats new.
-Removed AIR injection pump
-Removed A/C (replaced with TPIS AC bracket Pully)
-Replaced Heads with New ZZ4 aluminum heads, valves, 1.5 roller rockers(went with cast) and valve springs(discovered a crack between the walls of the exhaust ports on the driver side) and to finish up bolted some nice new "Chevrolet" valve cam covers
-Flushed the coolant, oil change, tranny fluid(Lucas Oil)
-Installed a ATI PB600 supercharger(not tuned)
-New aluminum Transmission oil pan
So I have been busy with some stuff, and got a question with the gear ratio...again.
Depending on what tune I decide to go with(Possibly painless performance next spring) I want my vette to launch nice and hard and the supercharger to gradually pull a little on mid range. Should I keep the 2.59 gears or look for a 3.07(rear)?
The reason I'm asking is because I don't want to spin. I'm not familar with a 3.07 gear or any ratio than what I have now and the application to fill out at P.P requires very specific detailed info, and I'm not sure If I want to keep my stock rear :ugh Oh, and fuel injectors I'm looking to run a "safe" 6-8psi and not sure If I should upgrade.
Thanks again guys for all your help
