Horrendous gas mileage issue.
So I have a 1985 gmc k2500 with 4x4, 350 and an edelbrock 1406 on it currently. I had a 1906 till they kept failing. Anyways this truck gets about 5 mpg, which I know is gonna be common, but I feel its still excessive. Any thoughts how to fix it? Note 1. I got this truck when my dad passed...- Geizhals
