Re: mileage motors
3.08 was standard on most trucks in the 80's, and I've heard of even 2.73's....with a 700R4. One of my friends had an '86 K10 with a 305/700R4/3.08 combo. With 32" tires it practically idled down the freeway, but got maybe 10-11 mpg going 75, and had no power, with its worn out, improperly tuned 305.
