All of my friends drive LS1s. I want to be able to beat the fastest one. It is a stock LS1 besides a CAI, Cat-back, Eagle F1s, and some suspension mods. In an LT1 what do you think would be the quickest and least expensive way to be able to beat him at the strip. I want to have a naturally aspirated car for now. :thumbsup:

well if you want N/A then get a 1.6 roller rocker/high duration cam setup, plus headers and full exhaust. And don't do any of that wussy hotcam crap, go big :) Unless you want good city gas mileage, in which case don't. Also get some higher ratio gears. All that should run you $1200ish.

Best way:

Get an automatic car and put in gears and a converter, CAI & exhaust, and an XE 224/230 cam w/1.6 rockers.

Cheapest and quickest way:

150 shot of N20, but that alone might not be enough if you are playing with modded LS1s

I dont want to do gears for now because i dont want to hurt my mileage a lot. Any ideas on what a big cam will do to it?

Cam and conveter will do it. Just be sure the car is a 3.23 geared one.

I want to leave the gears stock though because it will be my daily driver. What do you all think about full exhaust and a cam?

That would do it. Honestly though, with a 6 speed...gears are fine. the 6th gear is so tall..

I am running 3.73s now and I still only hit 1750rpm at 70mph.

But a cam and full exhaust should get you there, but you'll need tuning too...(PCMforless!!!)

I'd say Kooks longtubes and a 227/233 from Combination motorsports.

Do you have to worry about emissions requirements?

Depends. Where is your "area"...I don't see a location.

You're going to need cats at a mimimum to stay legal. If you are in California you can forget longtubes all together as none are C.A.R.B. legal for the LT1.
