Well, I got my mileage up to 10.5 mpg. Half highway driving and half stop and go. Guess balancing my tires and driving with the tailgate down helped out. Just need to work on making a new flow-thru tailgate. Checked my alignment today and the "toe-in" was off just a little bit. Thanks for the tip JB. Also checked the jets in my carb, they were 64c. Performance store I went to only had 65? Does anyone know if thats the smallest jets they make for the quadra-jet carb? <br>I'm pretty sure my 1/2ton 4x4 is running 373 gears. Looked at Chucks info and there where only three possible gears. Anyone know how I can fine out for sure? <br>There are two other things I wanted to try but the 700R4 tranny didn't seem like it was a good idea. Tranny shop said I'd have to use an adapter, but it was pretty weak. Or I'd have to have one specially rebuilt. Too much money. The other is an electric fan. Seen a post on another website that said it increased mileage by 2 mpg and increase horsepower because the engine didn't have to drive the fan. Anyone try the electric fan? Does it keep you vehicle cool? If anyone has tried this let me know. I think the electric fans run about $90. Want to hear pros and cons before I make a decission to buy one.
