Twin GT37, L92-headed, 408....camshaft? I am doing a 1971 Chevelle transplant with a modded 700r4 and 3.73 gears. I plan on running about 9.3:1 CR, pump gas, and as much boost as I can get by with (without oringing or similar stuff....less than 15psi of boost for sure).
I have looked at the LS9 camshaft which is a steal of a deal, but is it right for my application? Lingenfelter also has the new GT9 which is a beefier version, but also introduces more overlap. I want a mean sound, but can probably get what I need with idle speed and timing, so I want a great performer for my application. I don't plan on pushing the car to extreme RPMs (maybe 6200 tops) and my stall would not even come close to 3000RPMs, so large duration cams probably wont be useful.
With the L92s exhaust flow characterisitcs, I assume I need more exhaust duration (which the LS9 and GT9 cams incorporate).
HELP? Anyone with a similar combo? Also, if the turbo sizes sound off to you, I am open to suggestions (they aren't bought yet).
Thanks guys...

IDK what you could be refering to with a GT37... but I do assume you are talking about a base model GT35r, as they are basically the only turbo I commonly see with GT37 wheels in them.
Either way, base GT35r's are typically good for 450whp each at 15psi, and 500whp each at 20+, so do the math!
