Re: 1970 c 10 gas milage
Mine before i started restoring the truck with a 383 a TH350 and 3.42 gears I got about 9-11 MPG in town and around 12-13 on the HWY around 65-70 MPH depending on your rear end gears and how heavy your foot is you should get a little better. NICE TRUCK BTW

Re: 1970 c 10 gas milage
Here is a poll i did on the subject.
Don't expect too much. http://67-72chevytrucks.com/vboard/s...d.php?t=172346 I've had a 3/4 ton longhorn, (4.10 gears) had a 300,000 mile old 350, never rebuilt, it got right at 10 MPG, then when I installed a high compression cammed out 350 in it's place, I got 13 average, and 16 MPG on 2 ocasions. Next truck was a 69 SWB 1/2 ton, with 3.07 gears, had a well worn 400 small block, 9 MPG, installed same cammed out 350 from the first longhorn, and instantly got 10 MPG every day. Couldn't get any more out of it to save my life. (RPMs were too low) 3rd truck, one ton longhorn, 4.10 gears, caddy 500... 10 - 12 MPG. |
