Gas mileage/carb question?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Also my truck gets better mileage now with 4.10 gears and 33" tires than it ever did with 3.08 gears and 31" tires with my 3 speed automatic.

thanks for all the advice, i really appreciate it.

I knew i wouldn't have enough info in the first post, i always seem to leave something out. Ok, I think i've got a 700r4 trans. I've got 33" tires right now, but was running 31's during the winter, and i haven't got the foggiest idea what my gearing is.(I'm not exactly mechanically inclined, just the basics pretty much)

I guess i'll take the truck down to my mechanic and see what he thinks he can do with the carb. Thanks again for the help.
