my '87 5.7L IROC VS '09 6.2L Sierra?
 

Hello everyone! I own a 1987 iroc-z and its almost time to take her out of storage! Theres a kid at my school that drives his dads 2009 GMC Sierra and claims it has the 6.2 vortec. He threw out the offer to race and I accepted thinking it shouldn't be too much of a problem. But, after taking a look at the HP rating on the truck I'm a little skeptical. Heres the stats of my car and his truck that I know of.


87 camaro

350 TPI with cermaic headers
Auto 700r4 trans w/shift kit
9 Bolt 3.27
full 3" Flowmaster 40's exhaust
at the most maybe 240-250HP?


09 sierra

6.2L Vortec 403HP est.
all stock
easily +4500lbs

Do I have the better power/weight ratio? Ive driven a 2006 Ram with 5.7L hemi, and that thing is pretty dam quick! what do you think?

your gonna get waxed hes got 4wd and more hp and tq if its any like the ones ive seen run the run mid to high 9s in the 8th and a iroc is low 10s from what ive seen basicly bone stock you migh wanna get on the bottle for that one getting beat by a truck while your in school just isnt cool lmao.

true but those those trucks weigh around 5500lbs. I'm hoping I can pull him off the line and take advantage of the TPI torque. I know I have more driving experience so we'll see! I'll post the results if anyones interested. any more guesses?

You wont pull em off the line they make more all around tq than your 350 and they have 4wd.Get a video of this cuz ive seen them run and a stock 3rd gen z28 aswell and stock to stock the truck runs way better.

I think it'll at least be a good race. Might win, might not, but should be pretty close either way if you know how to launch. Give it a shot and let us know what happens. If you lose, well, the car is 23 years old.

stock they run mid-high 14's at around 88-90mph. you're gonna have your hands full with this one.

Yeah good luck man.. this is gonna be a tough run

at the dragstrip last year, my friend let me drive his stock 2009 6.2L sierra and i ran a 14.48 at 96 mph. good luck. let us know how it turns out

granted the 100+ more hp but all that weight is gonna be alot to haul *** with. from the whole you might stand a chance lighter = out the hole faster. but from a roll your gone, i remember watching a lt1 trans am race a ram 4x4 super duty or something, the lt1 pulled about a car length.

but its still a truck though.. nothing special.
