what is a good calculator to use to figure out a general rule of thumb on what a particular combo should attain?

I'm a good calculator when it comes to guessing #'s. What kinda mods/tranny are you running?

i sent you a pm..

Hmm...I didn't think the car was this heavily modified. I thought you were gonna be talking cold air intakes and catbacks. Either way, I'll take a guess just for the hell of it. I'd say that setup would be close to 430~440hp @ the crank...360~370hp @ the wheels. I wouldn't be surprised if I'm off though.

forgot the custom 4" cold air intake, custom 1 3/4 LT headers and 4" exhaust.

At the wheels. Power peak at 5700 maybe? You said somewhere else that the heads were worked also. Only you know how much. There could be 20-60hp in a correctly placed head massage.

Honestly I dont trust any numbers I've seen floating around. GM claimed 270-285 cfm at .500-.700 lifts a while back and now someone said SDPC shows a 230'ish CFM at .500 which is what a Vortec head flows roughly with it's 40cc smaller port...So... Fastburn heads are basically a GM developed ALum head with 210/78cc ports, 2.02/1.60 valves, a fastburn chamber with a better spark plug location, and so called "perfect ports". They really should make good power.

the compression is only 9.7.1 right now...the rod length is standard and i'm not sure on the timing right now. regardless i need to find someone who knows a thing or two as tpis really screwed up on some parts unfortunately.
