Do i need to lower compression for Vortec supercharger?
355 with flat top forged pistons, 0 decked.. Dart pro 1 heads (64cc) Estimated compression is 10.2-1
Can i run this compression with the vortec supercharger if i run a air to air intercooler??
I want to make 600-700hp!! Not really concerned about lower end of engine as if it blows it goes!
Current intake is a Dart COOL CAN.. identical to air gap intake!
Current carb is Demon 750 DP!Project JUST-N-SANE
84' Camaro Z-28, 355CID,9.0-1 compression, ATI procharger 9psi (over 650HP),T56 6 speed, 3.73 Motive gears! 11.70 at 122mph in the 1/4 while babying the throttle to keep the tires hooked ,with pump gas! (NOW INTERCOOLED)

With the supercharger you are looking to get around 9 to 1 or 8.5 to 1.
Hopefully Jody steps in he knows alot, I know just the surface.

So depending on the power you have now it may meet your goals. Be much better to get it down to 9:1 or so and turn the boost up; it will make alot more power safer that way.

How thick are the current gaskets? Problem may be that the quench will go out the window and may be more prone to detonate even though the compression is lower. Originally Posted by WELTERRACER

THE Gaskets currently in the car are stock repacement gaskets from felpro! Im guessing in the .050-.055 range
