improving fuel milage question

[landon4421]

Hello everyone !

I was wondering what I can do to improve the fuel milage in Jenna's 71 C-10. But I was also wondering how to figure out my fuel mileage now. It is 33 miles from home to work, and it takes a 1/4 of a tank to get to work from home? Is that normal?

But as far as the fuel mileage issue. Her truck is a run around town and a back up goto work truck. We use it to go camping and it pulls a trailer. < 1972 c-10 long bed & frame, trailer > The truck has a new crate 350, 15,000 miles. It has a edelbrock preformer intake and 600CFM preformer carburetor. Also has HEI. The transmission is the stock auto, and the gears in the rear I have no clue. I will be looking soon, mabe this weekend.

My question is if I take the 4 barrel off and put a 2 barrel on the engine, will the truck still pull the trailer? Will it improve the fuel mileage? If I chance the gear ratio in the rear, will that work? Or mabe a different transmission? I did not ask the guy we bought the truck from if the transmission had ever been rebuilt? Could the tranny have anything to do with the fuel milage?

Anyway I have rambled enough. Thanks Landon
