The setup is very stout btw, everything is solid. Most of the mods have under 1k miles on them, motor has about 6k on it now(and i broke it in properly). I consider myself a good driver (as do most of my friends). ive run better times with other people's cars than they could themselves (and they were good drivers also). not bragging or anything.
any other guesses?

i have full eibach and bmr suspension...man i gotta get this thing tuned so i can put down some numbers!! i'm not too worried about the 1/4 mile time anyways..still got the stock 10bolt, and dont wanna blow it yet(at least til the end of the summer lol), so im sure the times wont be anything stellar. im just looking to get some good dyno #'s, and trap numbers.

what kinda compression?
I made 325rwhp with my cam-only cc503 car, with midlength headers, 3.73s, soft tires and an unlocked stalled auto
oh yeah and that's on a 140k mile motor
I imagine i'd be making around 350-360rwhp through a t56, so a fresh motor + more compression + ported heads, I don't see 390rwhp+ being impossible
high 300's is good for about a 117-119 trap, as far as ET i dunno too many variables in a 6 speed car

compression ratio is a tad higher than stock...can't remember the exact number but im sure i have it written down somewhere around here. anybody know of the highest dyno #'s n/a with cc503?

I cant really see that setup hitting 11's partially since I dont know whats done to the heads and the 3.42's aren't really the optimal gear. I would say low 12's with good driving. As far as dyno numbers hard to say again because no specs on the heads but my guess would be 365-375.

Mine put down 335rwhp a few years ago when I was running MAC mid's, stock heads and the cc503 on a mail order tune. I am sure you will hit 370+ on the dyno with ported heads.

We built a friends car very similar to your with home ported heads (by me) .
It had auto tranny (3500 stall) 3.42 gears. It dynoed 365 before tuning and tuning gained it another 11 to 15 across the board, peaking at 372 rwhp @ 6300 rpm. His first time at the track netted 12.40s @ 112s. We had the "lift to shift" issue from 2nd to third so it probably had a tenth or two and a mph there.
