at low 12s.My Procharged Vette made 514rwhp through a 2.5" exhaust and the stock blower pulley with the stock bottom end through a stock 4L60E w/ unlocked converter.. 2400 stall, 3.73 gears, 18" BFG Drag Radials, etc.
It ran 11.1x @ 127 best.

Let me edit that a little bit for you 
Also, if you're capping yourself at 25k and buying all new parts, you'll never put together all of the parts you listed. 30k would be more realistic:
$12,000 for the car
$5000 for the supercharger kit
Less than $1500 for the heads (assembled) and a matching cam - 317 heads are around $300 used. A cam is $399 and the hardware is another $600.
$2500 for the 12-bolt
$550 for the Ram Powergrip HD w/o flywheel
$1500 for the tranny rebuild and shifter
$400 for Drag Radials. Who needs wheels? Some nice Nittos, BFG Drag Radials, or M/T ET Street Drag Radials will work perfectly.
$1000 for the exhaust
$300 for basic bolt-ons (lid, pulleys)
$500 for a dyno tune
Just saved him a few thousand

haha, I know low 12's is easy with a blower. I was just trying to say that I want to run low boost and not blow the stock internal motor up, I'm not looking for max power on stock internals here. I looking for reliable, streetable, and perferably without doing engine internals like a cam or even heads if I can get away with it.
Thats why I wanted a blower, I thought I could just use moderate amount of boost with stock internals and get low 12's easy. I'm sure I can break into 11's all day if I push it, but I would think on stock internals it might not be the best idea if I don't want to kill the engine. I just know from personnel experience, with nitrous, on 100 shots the engine can only take so much especially being an older car. I do plan on eventually doing a forged buildup one day(maybe getting a shop to do a whole crate engine) then putting a blower on that.
I jsut ahve to think about things, I mean, heck, for 25k I could just go out and buy a 2003 cobra.
But I like buying the SS idea because I could get the car for 14k, and just mod it as I have money and enjoy doing that as time progresses. Buying the cobra would be fun, but it's not like I have to do anything to it at all. I like tinkering around.

Ah, I didn't know the 317 heads were so affordable. Is that the casting number for the L92?
As for wheels... he said he wanted to go to 315s... Not gonna mount those on the stock 9" wheel.
Also, do you think the Ram Powergrip HD would work well on a heads/cam/blower car running drag radials?

I've had no problems whatsoever with mine. He's talking about running heads to lower the static compression ratio and didn't mention a cam. The Ram Powergrip HD will support over 500rwhp without a problem. It's one of their high-end clutches that Ram produces and is rated at 120% more holding power than stock.

You don't want to run L92's on an LS1...
6.0, 317 casting LQ9 heads from the trucks are what you want...
The L92 heads are huge runner, torque killing, rectangle port heads that will require a crappy L76 intake, with matching throttle body...

To clarify.
You can't run rectangle port heads on a stock bore LS1 like the LS7 or L92....besides, the runners are like 260cc+ on both heads...it wouldn't do anything on 346 cubes unless you were spinning it 8000+.
You can run the 6.0L LQ9 317 heads on the stock LS1. It will decrease compression by around 0.8-1.0 point.
Better?

Alright, it seems some of you are a little slow, so i'll try some pictures to ease it along...
6.0 truck castings, designated by 873 (99-00 LQ4) 317 (01 and up LQ4) 035 (02 and up LQ9...Cathedral port heads that are similar to LS6 on the exhaust side...
Cathedral ports LSX based heads:
L92 castings, designated by casting numbers 823 or 5364...Are the 6.2L V8 heads used in the Cadillac Escalade, GMC Sierra denali and Yukon denali, as well as in the Hummer H2...They have huge RECTANGLE ports...L92, LS3, L76
Rectangle Port heads:
hope this clears it up

Hey Hawk,
I recently had the same dilemma as you. I had an'97 Z28 6M. I loved that car. It had mile bolt-ons, ran mid -high 13's. BUT it had 167K miles when I got rid of it last year. The A/C would have cost over a grand to fix and the clutch was slowly slipping away. I traded it in for an '05 Malibu Maxx fearing the rise in gas prices. I should have kept the '97; it would have been paid off in less than a year, then I should have bought something else.
After a few weeks in the Maxx I was scouring the classifieds....LOL. Finally after a year I took a hit by being upside down on the Malibu, but I got a 25K mile 2002 Trans Am, Navy Blue, 4A/2.73 gear car....clean Carfax, clean Autocheck, clean GMVIS....been only back to the dealer 2 times for rear axle pinion seals.
You only live once, at least be happy with what you drive.

I have been thinking of getting one myself.As far as the Cobra sure its fast but Im not into supercharged cars.Now Turbo's are a different thing.They get great gas mileage and unless your rich that makes it an easy choice.
