Can you guys/gals post your truck specs and what you get for gas mileage? I'm talking lift size, tire size, axle gearing, and motor specs. Also the year and what the vehicle is.
I'm going to figure mine out soon for my 84 RC and I'm curious to see how mine compares to others.
I was doing 20 mpg hwy with 4.10's, np435, light wheels and 33's, 360, splitter, fully covered bed. Went to 35's everything else still the same and went to 19 mpg. The new motor seems to be doing better on gas so far but it hasn't been tested as fairly as the other motor, but going by days of use vs gas in tank vs the old motor in city driving and she is better.
87 1/2ton 4x4 with a 89 318 bored 30 over, MSD ignition on all parts K&N, Edlebrok intake and carb I was getting 15mpg city and highway with the 435tranny. Running 28"Workhorses (can't afford the lift yet... damn schooling) and 3.55 gears. Just finishing my motor overhaul so we'll see how it gets then
Mine is a '75 D 100 with a 400 2 bbl, 31" tires(BFG's), 4.10 gears and 727 w/ NP 203 full timer..
It gets 8-10 mpg in the summer with the plow off and 6-8 mpg with the plow on.
I may throw a 4 bbl on it soon for S&G's, but I doubt I can stand to run on the primaries alone to get the mpg up.....I have a heavy foot.
This beast is mainly used on short trips around town to the dump, to the store, to the fishin hole.
83 W-250: 200k mile 360 with 600-cfm edelbrock carb and intake, heddman headers and 2 chamber flowmasters. np 435 trans, np205 case. dana 44 / 60 axles with 4.10 gears. 35x12.50-16.5 bfg mud terrains at 50psi. getting about 6-9 mpg depending on driving habits and what i've got hitched up behind it. probably would do better if i reset the timing and put in a set of plugs that aren't completely wasted
When stock, 84 Ramcharger 318/NP435/can not remember the gearing 14 MPG. Now 61/2" lift 360/NP435/4.10 gears/35" tires/ Holley off-road carb/edelbrock intake/large roof rack/and about 500 lbs of tools, accessories, armor, winch about 8 MPG and about 110,000 miles on a rebuilt motor.
