i have a 2004 gmc sierra with a 5.3 its a ext z71 4wd. My current mods are_ air aid cai, Ebay long tube headers, FLow master super 44 single in dual out, cats are deleated running a 91 nelsons tune, and vette servos in the tranny. im running 33in tires on 16in rims " there very light tho surprisingly" 3.73 gears.

im going to be installing a TR 220/220 cam 114 lsa and a 3000 cir d converter

im just wondering what you all think it would/could possably run. thanks for the help guys...

 

Depending on DA you will probably run a mid-high 16

 

lol tell me your joking? im shooting for around mid 13's? mid-high

 

Oh sorry i didnt see you were adding the cam and converter. I meant as you described it now. But it all depends on your altitude.

 

High 13s with the cam and converter. Anything better then 13.75 and I would be surprised. 14.0 would be my conservative guess.

 

haha ya my bad, um im not sure the altitude im guessing 2900 ish maybe? im just trying to get a rough guess on the 1/4 mile time. ive riden and ran agianst alot of trucks in town and they all say my truck runs very strong for some reason. and with the cam and stall im hoping to be able to hand some other trucks in town a whoop'n so far im one of if not the fastest gas N/a truck in town. but i also live in a smaller town...

 

You're gonna get your feelings hurt.

Bumpers on here has 6.0 cammed/heads/headers/3400 converter/4.56 and managed a 8.9 1/8th mile (~13.8 1/4 mile) in his ECSB 4x4. So with your setup, I'd say mid 14s. Unless you're in Texas, and you'll run 13.2.

 

At 2900' You may be able to scrape a high 14 to a low 15 with the cam and converter. I'm at 2200' and stock SS trucks can barely break into 15s here.

 

welllll i must be missing sumthin? cuz i can walk the 2 SS trucks in town here and one has catback and cai and a programer...? idk just say'n?

 

what does the truck run now?
