right... lol na i should be low low 13's right now thats not to bad for what im working with

 

more than likely mid-high 13s. my truck ran a best of 13.7 in Tucson. I had to go to Chandler to run my 13.2. And your about 500' above Tucson

 

lol ok, mid-high in tucson, low in phx... lol jewdith

 

There are probably more combinations of 5.3's with superchargers than anything else, and they work well. Before I built my current engine I had a 5.3 with a Vinci Ultra-torque cam, a Maggie 1900 and a 3" exhaust with Magnaflow muffler. It ran a 13.1 at 109 at 3600 feet elevation. That was with a stock 60e. The transmission lasted exactly one year.

 

You dont want to regear?????? This is just stupid! You have a heavy 4wd truck with a tiny engine that doesnt make nearly enough power. You are pissing in the wind if you dont regear. Stock gearing is from 3.08-3.73 on half ton trucks and just wont do the job. You need a minimum of 4.10 to be able to do anything with a 5.3........and then you dont have a 6l80E.......Just take the advice and go with it. Understand that we are trying to help you out b/c most of us on here have been in your shoes at some point.

 

What's the price tag on throwing some 4:10s in my truck then. I have 3.73s now. I realize that will be a big gain in bottom end. How much exactly?

 

What size tire are you going to run?

You are looking at around 1k for parts and labor per axle.

 

holly hell, im staying away from ur hook up... lol $1300 around here parts and labor tops.

 

I'm gonna go to a local driveline shop here and get 4.56s. My tires are 32x12x20. And my rims are pretty heavy. Not too worried about mileage

 

perfect combo with the 4l60e and 32" tires!
