Hey guys,

I'm planning the final stages of my car. Ultimately, I want to have a Procharger putting down 700+ to the wheels. I'm going to do it in steps, though, if I can.

Current setup:

Forged rods
Forged pistons -9cc w/ valve reliefs
Stock crank
Stock block
Stock heads milled .040"
Cometic .040" gaskets
TR 230/236, .592/.602 112LSA
LS6 intake
Stock TB & MAF
SLP Lid
1-3/4" LTs with Hooker catback and cutouts for the track
Stock fuel system


Now, I got the dished pistons with the intention of being able to lower my compression ratio by swapping the heads when I'm ready for the Procharger. With the milled heads and thin gaskets my CR is about stock. With 72cc combustion chambers and stock gasket thickness, I can get it down to 8.9-9.0 according to my math.

What I'm hoping to do with this next stage is to get heads that will lower the CR, a FAST 90, 90mm TB, bigger MAF, and a HUGE cam. This way I could break up the cost a bit and still get a power increase. Here are the questions I have at this point...

1) Will the lower CR be enough to kill any power gains I'd get from the heads/intake/cam?
2) If the answer to #1 is "No," then I'm trying to decide between Stage 3 6.0L heads and L92 heads. Both give me the CR I want, but the L92 sticks me with the L76 intake. I don't know which setup would flow better... L92 w/ L76 or 6.0L w/ FAST 90. Whatcha think?
3) Again assuming that the answer to #1 is "No," will the stock fuel system be able to put up with a setup like that, or will it need to be upgraded before these changes? (Yes, I realize it'll never handle a Procharger, but I'm trying to determine the order of modifications.)
4) What runner size would be optimal for the H/C setup I'm describing?
5) What runner size would be optimal for a Procharged engine running 700+ to the wheels?


Thanks in advance, guys. Let me know if you need any more info to make educated suggestions.
