Gear ratio and Gas Milage

[bigbear8]

i would like to know what a 1984 K5 with a 305 v8 gets in gas mileage, and what the rear axle ratio is

thanks

That depends on a lot of things. Auto or stick, general tune of the engine, tire size and lift, city or freeway, how aggressively is it driven, etc.
There are just too many variables to consider. Some people get as little as 8 MPG some as high as 15 MPG or more.

if you look on the axle tube I believe there will be codes so you cn differentiate what gears you have, and if it is a locking rear.

My 84 Jimmy with the 305 got about 10-11 MPG no matter what I was doing. After switching to a 350, I actually get between 12 and 13 depending on how I'm driving. Shocked the hell out of me, but I guess the larger engine does less work to keep the truck moving. Go figure.
