You used the stock 04 manifolds right? Any frame notching needed?

What kind of mpg you getting with the 5.3?

Re: 5.3 swap build so far
 
well mine should do even better since mine is 2wd with stock 235/75/15s on it.

dman1982 06-09-2014 12:59 PM

Re: 5.3 swap build so far
 
It might, a lot of it depends on the gear ratio, tune, and how you drive

ivorton74 06-09-2014 01:51 PM

Re: 5.3 swap build so far

Re: 5.3 swap build so far

Depends on your trans type and tire sizing, one may mathematically work out better for ya. 3:73 12-bolts are easy enough to find, so simplicity might lead you there.

id say 3.73's would be good to go, should pull good, and not be too high on the rpm's at highway speeds
