Re: 5.3 swap build so far
 

Using the truck as a dd, loving it so far, gotta do some minor things other than that awesome power

Re: 5.3 swap build so far
 

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
 

Ya used the stock manifolds, had to do a little cutting, not sure what my mpg's are yet, just got the speedo calibrated the other day

Re: 5.3 swap build so far

Re: 5.3 swap build so far
 

Shop around!!! I'm always looking!!!

Re: 5.3 swap build so far
 

got the speedo calibrated good the other day, its like 1 or 2 mph off, but works pretty good

Re: 5.3 swap build so far
 

somewhere somebody on here ask me about my MPG'S, got a rough estimate today, putting around town and just going to school, getting on it from time to time I'm getting somewhere around 20 mpg's or so, ill have more accurate numbers here soon...just gotta get gas and do the math

Re: 5.3 swap build so far
 

Sounds good to me!

Re: 5.3 swap build so far
 

Ya man

Re: 5.3 swap build so far
 

so far my mpg's are between 16 and 20, i need to quit showing off!!!!

Re: 5.3 swap build so far
 

Thats pretty damn good considering yours is a four wheeler and you got those big ole meets on there

Re: 5.3 swap build so far
 

True man, not bad at all I don't think

Re: 5.3 swap build so far
 

well mine should do even better since mine is 2wd with stock 235/75/15s on it.

Re: 5.3 swap build so far
 

It might, a lot of it depends on the gear ratio, tune, and how you drive

Re: 5.3 swap build so far
 

what gears are u running again? mines 3.08

Re: 5.3 swap build so far
 

4.56's...had 2.73's...they didn't like 35 inch tires

Re: 5.3 swap build so far
 

I want to go with 3.55 or 3.73 when i have some money

Re: 5.3 swap build so far
 

I'd do 3.73...tranny depending

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.

Re: 5.3 swap build so far
 

I'm running a stock 4l60e from an 02 truck and 235/75/15 tires.

Re: 5.3 swap build so far
 

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
