It depends some on how you drive it and what it's used for. What transmission and rear gear ratio. I get between 12 to 14 with my 73 F-100 , 2 wheel drive. It's got the 302 , 2bl carb ,3 speed transmission and rear gears are 3:25. You having a F -150 , a lot of them had 3:50 rear gears if they a 2 wheel drive. You should get about the same as i get i believe. If it's a 4x4 then i don't know. I should be getting better than what i do.

2x... a rear gear of 2.80 or 3.00 will stretch the MPGs. That and a well tuned engine and the driving habits of a nun.

I routinely get 14.5 mpg with mixed driving. That's coming from an 81 4x4 f250 with the 302, zf5 and 4:10s. Sounds to me like you just need to get your 302 properly tuned.

Fuel mileage
With my 75 F-100 w/ 360, my pops use to say it got 8-10 gallons per mile whe he had it! And it would pass everything but a gas station!

If I put 3.00 gears in the rear what gears should I put in the front to balance it out my f150 is 4wd with 6 inch lift and 36's

ya you probably have 3:50 stock and 36's are to much. 33's are about max with that kind of gearing. 4:10's would be much better for 36's

Ok so 4:10 would be the best gear ratio for the lift and tires what about a new cam what do you think the best to buy would be?
