Re: Trying to do the logical thing.

I look at it this way, your mileage may vary. BUT
When g.m. had Both a 350/th350 carb truck and a 350v8 /7004r carb truck.
The city mpg was the same and highway was 1 mpg difference.
So pick your poison .
The O/P already stuffed 3.73's in the rear, so at this point a 7004r might make sense, I think his math is suspect. His daily drive is not going to be all in 4th gear at a steady rate. So I think what he THINKS he will save in fuel cost, is um, well. you know.
