If you would stop being a ***** and shift it at 6300 you'd be faster. Your "I want low end power" crap is getting old. Quit asking the same question just to get a rise.

OP just needs a nice turbo in his life. I shift mine well before 6200, guess I get beat by LS1 cars.

Damn you internet logic!!!!!!!

OP, get LE2s and nasty cam, spin that bitch to 6500 and run 11s.

Shownomercy- That's the answer a twin screw turbo! Bufmat- That twin screw would make more "low end power" lol. I could see shifting at 6300 getting me another tenth in the quarter.

With a LE stage 2 wouls a stock intake be ok or would you have to change the intake. Am i correct in saying these intakes are good for 400 h/p?

Maybe with the right suspension/bolt on mods. I think a setup like that is getting most of the gains off the line. I believe it would get killed badly by a head/cam car on a roll.

Mid to high 12s, on a stock 10 bolt, so being easy off the line and 1.8-1.9 60s, is very easy if you shift at 6300 with long tubes, CAI and a tune.

Unported stock intake has been to at least 425rwhp on a stock shortblock and the only simple aftermarket "upgrade" the edelbrock looks to actually hurt power if anything. So yeah, stay stock.

Not sure how familiar you are with drag racing but a 2.2-2.3 60ft is terrible. I used to pull 2.1's in a fwd stick car on a 225 series general UHP tire. 2.0 should be your goal at minimum. That would knock a half second off your 1/4 mile time at least.

He might have crappy tires to begin with, I had some sumotomos and kumhos at one point in the past that wouldn't hook for it might be worth it to take one step further and get some drag radials....I recommend the Nitto NT555R, they seem to handle better in the curves than the Toyo Proxes Tq DRs they replaced.

I'm not a fan of high rpm power because I don't daily drive at 6500 rpm. Now if I had the money to get a completly forged shortblock my story might change. Then I would aim for 400rw. I will look into that cam that is a step bigger though.
My old "cam only" setup made 358rwhp and 370-ish rwtq with untouched stock heads and peaked right at 6100. So if ~360rw is all you're looking for, just get the right type of cam and don't touch the heads.

You will NOT sacrifice any low-end power by going bigger if you pay attention to what type of cam grind you select, and with ported heads you will stand to make a bunch more power. In short, there's little point in getting any sort of ported heads if you're going to do a peanut cam grind in the 215/227 range as you stated.

Mild, bolt-on LS1 cars with just longtubes, exhaust and a lid can make in the range of 340-350rwhp, particularly the 2001-2002 cars. You're going to need more than 350-360 to "destroy" them.

Why anyone would do a H/C setup on a LT1 car and not shoot for 400+rwhp is beyond me. I don't "drive around at 6500rpm" every day either, but that didn't keep me from wanting a setup that put down good numbers and is a heck of a lot more fun anywhere on the tach than what you're talking about would be. Any decent H/C setup is quite a bit of money and work in one of these cars. The additional cost to do LE2 and get a real camshaft is marginal over what you're talking about doing, in terms of driveability and money. You're already going to have to add $300-$400 to what you're spending to get a decent tune, so why not do a stronger setup?

Camonlyjabroni, Ahritchie,- I had bald tires at the strip!! I have B F Goodrich comp 2's on the rear now. They def hook better and should drop 1-2 tenths off my 60 when I run it again next april.Hellteeone- My goal with H/C is anywhere in the 12's @ 110+. I dont care about the 400rw bragging rights or 11 sec cars that idle like ****. I agree ls1' s are no joke with bolt ons. I want to get away with a solomon mail order tune. Would that work? I might go bigger with the cam but not at the cost of driveability. Would a cam with 230 duration idle okay? What LE cam would you rec for a 12 sec Daily Driver? 224/230 @ 112 lsa? I would think that cam would get at least 370rw if tuned properly.

You can get deep into the 12's, maybe even high 11's with LPE's CNC heads and a 211/219 cam at full weight given good track conditions. Good news is the car will behave like stock, bad news is it'll also sound pretty stock too.

Stock cam can give a 12 second at 110 pass if you are not a ***** and take it to 6300rpm.

That cam would idle fine IMO...a bit choppy yes, but it's only 2 degrees more duration than the LT4 hot cam which is considered pretty tame and is very drivable for DD use.
