They made S10's with a 2WD 2.73 ratio, I know a higher gear ratio should help some on fuel economy, but does it really make that much difference? I currently get about 15mpg with the 3.73, is a 2.73 ratio going to make enough difference to be worth changing out the rearend?
This is a 1937 Dodge Pickup mounted on an S10 frame, it's got a 350 SB with about 220hp and a Turbo 350 tranny.
I found a 2WD 1999 S10 Blazer with disc brakes and was thinking about upgrading to disc brakes, the complete rearend is 100.00 but its got 200,000 miles. The disc brake parts are supposed to bolt right on any stock S10 2WD rearend.
There's nothing wrong with the rearend I've got now, plus the speedometer is right on, if I change the gear ratio I'll have to change out the speedometer drive gears.
What should I do, keep the rearend I have now and add the disc brakes to it, or find a 2.73 2WD rearend and upgrade it to disc?
