I currentlly Own a 2003 gmc sierra EX cab Z71 that runs a 14.80 1/4 mile.
I have some money to spend like 3-4k. So I can dump this in my truck and run 12's or buy a camaro or TA, or GTO. What would you rather do.

 

i love trucks,i dont know your mods but its going to cost more than 3-4k to get that truck in the 12s. but good luck

 

Everbody has fast Camaro's, Birds and GTO's. Be different. Good luck making it to 12's for that amount though.

 

and when you beat the camaros birds and goats in your big *** truck it hurts them that much more. I got the pleasure of playing with some cars this weekend and the look on their face was priceless

 

 

I couldn't agree more.

 

I think I will be close to 12's with 4k. My truck only has bolt-ons. I think with a 3600 stall, 224-224 cam mild heads and a good tune it should be close. At least a mid to lower 13. Don't you guys think. I will post some guesses and proces of what I think.

Cam,springs,gaskets- $750-$950 .6-.8 second drop 14.0-14.30
Yank 3600 stall- $695 -$995 .8-full second drop 13.2-13.50
Head work and good dyno tune $1200 -$1500 .2-.4 drop 12.9-13.20

price $2645- $3445

Should this be pretty close. Let me know

 

What r your exact mods? You are running a good time now!

Ok, the thing is, you need each of those thing to get the gain you stated.

What I'm trying to say is: If to just do a cam swap, and no tune or stall, your time may only improve ,1 or you will loose time. the stal will only give you .4-.5 and your right on with the tune. I think with those mods, you will only run a mid 13, if that. Remember, your truck is a lot heavier than others.

And I also think that is too much cam for a 5.3 ecsb z71....but who knows, I think a guy on here(trever1t?) did it, but he hasnt went to the track I dont think...

I would recommend a 220/220 for the max on a stock cubed motor.

good luck on your build!

 

A 3600 stall launching in 4hi will only net .4-.5. Well I guess I need to call yank back. They said that kind of stall launching in 4wd should easily gain 8 tenths. And also my brother has a 02 TA and put just a 224-228 cam in with a tune a gained almost a full second. Without a tune he still gained 3 tenths. But who knows I guess every truck is different. But I can tell you that I do have a strong running 5.3. With only bolt-ons I can beat stock SS and VHO's pretty good like 2-3 lengths

 

Oh ya my mods are custom intake, UD pulley,electric fans, long tubes, no cats, true dual, predator program. with full weight and on 18inch wheels I run a 15.2-15.40. with my 16's I run a 14.80-14.9. And that is only stalling at about 1400 rpms. So I think that 3600 will easily net a .7-.8 gain.
