Ls1 conversion- power estimate? anyone like to hazard a guess what sort of power (flywheel) and torque the following set up might make using a carb conversion/msd setup?
stock 2000 Ls1 5.7L
edelbrock performer manifold and msd ignition pack
750cfm BG Demon carb
220/220 deg cam .56 lift
ATI crank pully damper
ARE dry sump conversion
4-1 tubular headers cermic coated
3" exhaust systems - no cats
pancake 14" air filter
no a/c or p/steering
rev limit circa 6500rpm approx.

Ill agree with that. Why not go with a bigger cam for more power? Youll need port work to get much more but I still think you could make it to 500hp pretty easy.

tbh I am suprised that it might make anywhere near that much? i thought the stock engine being circa 350bhp that the above should clear 400bhp reliably enough.
i've only gone for a very mild cam to keep it all ultra reliable and driveable. its going in a lightweight track car so anything 400+bhp i would be pleased with anyway, plus there would be scope for future power gains then if it ever gets boring!

Carbs on LSX engines really open them up. You can get a ton of cheap HP by going carb. 475 seems a little high, but you'll definitely be making more than 400+. Myself, i'd trust the lower estimate of 450.

I dont know about that, i cant get mine to run with the stock internals camaros. I am sure i have some tuning left, but i am a 1/2 second off and lighter.
