MPG this particular rig.

[Caleb1]

Whatkinda gas mileage could I expect for this particular rig: 87 4 banger, 35 inch tires, 5:29 gears, 5 speed stick. Headers and exhaust. Think I could pull 17-18 MPG with an easy right foot?

[Bakemono]

Nope. I think if you get 14 mpg you're doing well.

Wow! That seems low even for that truck...

i think you may not even get 14. i get 17 with a 20r, 4spd, 30 inch tires and stock gears. (1980 4x4)

big tires = MPG down the drain on a 4cyl. i get maybe 17 with my 31's 5speed. (only ever checked it once, it was like 15 or 16 then. I usually accelerate pretty hard though. Love to bang through those gears.
