I am not sure if i want to sink money into my 2002 Silverado ext. cab with the 5.3 unless it is worth it. I am curious as to what power it could make and what times it could run with the following mods i would do.
3.73 gears with a Eaton Posi
3000-3200 Stall
Decent Cam, bigget than a LS6 cam (I know that dosent help much)
Cold air intake
Pacesetter LT's with duel exhaust and cutouts
Some type of programmer
And my NX Express Nitrous Wet kit that i was going to put on my 3000GT (just a 100 shot for the truck).

So with those mods what do you think i could expect, i know it depends on the cam specs alot, which i don't have, but just a ball park. I also live in Florida so I am sea level, and I ran a 15.98 in horrible like 95 degree weather.

 

you will be in the 13's easily on the bottle with those mods. VERY easily with a TR220 cam and about a 2800 stall... I expect to dip into some 13's with my 125 shot... I'm on stock 3.42's, stock cam, and stock convertor... I have LT's, ORY, full exhaust, intake , tune, t-stat, a couple bolt ons and like I said, I am hoping for some solid 13's in decent weather. I have an ext cab too...

-I say go for it man... after all, this is PERFORMANCE trucks... not, "I like to get great gas mileage and go to the grocery store" trucks LOL....

 

13's easily on motor, 12's on the spray

 

If thats true then as soon as i sell my 3000GT I will start ordering stuff, i would love to wipe an evo or STI's **** with my truck and see the look on ther face.

Who cares about gas milage? LOL, if i did I wouldnt own a ex. Cab Truck lol.

 

if you can hook up at the track i agree with tx

 

I wouldnt doubt 12's either really, I was being conservative because of the sorry atmoshpere...

 

yeah, well luckily i am in Florida at about 21 feet

 

where bouts in florida. i run at gainesville when the weathers good.

 

I am in Stuart, about 25 miles north of West Palm Beach, I run at Moroso.

 

I would say mid to high 13's motor, high 12's on spray.
