Also, for my engine with 4.10 & 235/75r15 tires , how do I find out what's the best speed to travel at where i get the most efficient gas mileage?


Ideally you should have been tracking mpg to be able to figure this out on your own, but........

On my 94 V6 AT, I found the sweet spot was around 2700-2800 rpm for best mpg. Lower rpms (2100 or so) for some reason resulted in poorer mpg. Check it out before you go, if you can.

Don't forget the JBWeld. <img src="/forums/images/graemlins/cyclops.gif" alt="" />
