Default What kind of numbers should I expect?

I'm planning on doing a head/cam/intake and potentially F/I setup this winter, but in the mean time, I am adding Pacesetter long tubes, a TSP OR Y pipe, and a P&P stock throttle body to my 2002 Z-28. It currently has the SLP airbox/smooth bellows/etc, the LS6 intake manifold of course, and a SLP Loudmouth I cat-back. M6 transmission. If I can find a basic tune at a reasonable price locally, I'll probably have that done once all the mods are on in a week or so.

I am just trying to get an idea of what kind of numbers I'm looking at with that setup - I am hoping for high 12's with favorable track conditions - is that a reasonable expectation if I do "my part"? I'm not going to throw slicks on or anything like that, just 10.5" wide 18" wheels with some 295/30 Firestone Firehawk tires on the back (which I'm hoping is a slight improvement over my worn out 16" tires).

Hypothetically speaking, what kind of RWHP numbers should I be around? Maybe 330 with a good tune? As far as I can tell, there's not much more I could do without cracking open the motor to start cranking out some horsepower.

Thanks!

we get these questions ALOT, but seems on average 330-350 is the normal. i have a buddy that had that combo but m/t dr's but auto with a 4400 stall that was running 12.4s. id say if you add a ud pully and a dyno tune from a good company 340-350 rwhp is possable. you should dump them tires though and slap some nittos on at the least, tires DO matter that much at the track. i had the nt555r's and dd them for 37k miles.

oh but when my car was full bolt ons and a good tune i put down 356rwhp and 345torq
