99 c5 with buncha cheap mods

cut hole in radiator shroud for fresh air, cut hole in airbox for more flow ( slightly larger than the 02 ZO6 hole), K and N air filter, stock "air bridge", high flow coupler, ported stock TB, TB bypass, LS6 intake manifold, B & B rear exhuast. How much am i making at the crank?

I've read about getting longer ZO6 valves with the 02 ZO6 cam. How much are they and whats the reason? Will i need new valve springs even if i keep the stock 6K redline?

280-290 rwhp w/ an A4
300-315 rwhp w/ M6

just a guess.

Edit: wait, is that an LS1? i get confused w/ dates and vetts.

M6 LS1 with stock 99 cam for now.... Thats it? i figured i was coming close to the 01 ZO6. thats kind of depressing. Anyone else?

I'd say about 360 at the crank. It's still basiclly stock.

15HP with all that? 345 stock.... 360 after almost full intake upgrades and exhaust??? 15HP with all those upgrades?

I figured 370ish atleast.... Was hoping closer to 385. Is the cam holding me back or something?

As far as intake upgrades...3-5 hp... maybe...
Exhaust... about the same- if its just the muffler, thats a sound upgrade you are still restricted by everything forward-
The ported TB is whats making your biggest difference-

Yeah it really brought my **** to life! I thought it was because the added velocity into the ZO6 manifold really made an awsome combination. How much with an x pipe, 02 ZO6 cam, and tune?

Guess a little bit of horsepower goes a long way when your car is lighter than most.... : D
