I blew my motor(5.3), and trans last week, I found a 6.0 with the trans for $1500. I seriously think it would take a lot more than that to run 13's with a 4.8. Im shooting for 13's in mine ita a 4x4, hopefully I can salvage my cam, and I'm putting a stall in with a tune and shift kit, and thats it for now.

Don't worry, more tuning, stickier tires and faster times are coming VERY soon.

my buddy left his 05 z71 with me b/c he went overseas. i must say it was nice to drive a stock truck again. not all loud and shaky from the lope, lol. but i'll never trade or sell my truck.

I was in the same boat as you with no 5.3 and 5 speed. So I just told myself I'd settle with the 4.8 as long as it had a blower on it. I have 5200 miles on mine and I've already done the mods in my sig. It will be a couple of weeks before I have any track times though. I highly recommend the "displacement replacement".

but whats more embarrasing
being beat by a 5.3L or getting your but handed to you by a lowly 4.8L that isnt running forced induction...but all motor
and is a half liter smaller than the competition
I totally agree about the no replacement for displacement..
I too would like to swap out, but I am limited to the 4.8L right now..
and it's a good laugh to spank some of that tail when I can..
but as usual theres always someone faster...
I take what I can get

, but how do you like that Detroit Tru-Trac? That's the LSD I've been looking at over the eaton or somebody else.For the guy who started the thread though, you could probably go somewhere in the 15's with the way the truck sits now.
