should i do it?
 

this guy with a stock gto wants to race me i have lt headers flows cai and 373 gears i know it has a ls2 but aren't they really heavy..who do u guys think would win

From a dig: You win.
From a roll: I wouldn't bet on anyone.

ok so dig it is lol

Your 3.73s, the difficulty in launching goats, and his IRS all work against him. Just keep it below 120, and I'd say you've got it in the bag! ;)

also i have an A4 when i launch should i put it in neutral and rev a lil then drop it to D? or just keep it in D and go?

Only if you want to ruin the transmission, blow the rearend, separate a trans mount, or scatter a u-joint.
What year is the GTO? 2004 had the LS1, which would make it even more interesting for you.

wow good thing i asked so how would i take off?...umm im not sure what year but im 100% sure its an ls2

Put it in 1st and load it up against the converter...

...push the brake down with your left foot and rev it (right foot) as high as you can go without breaking the tires loose or creeping...

On "green" or "go" or "arm drop" or whatever, take left foot off of brake pedal and smash right foot gas pedal to the floor... run the RPM as high as you feel comfortable and slap it into 2nd, etc...

Whoop his A$$ then record it...post it on youtube so the rest of us can watch it :)

Race him for pinks!

aright thanks and ill try and record it
