Well, I've got a very similar setup, 85 F150 4x4 C6, 3.55 gears, 33" mud tires, but the best I've done in the past few months is 9mpg. For a while last winter I got a real consistent 5mpg, but that was due to a dead choke. The carb is pretty much dead, but she runs so I don't really care right now. I just got a 95 EB Bronco with a 302, so the 85 is gonna be more of a toy than a daily driver. Not sure how the emissions test here in MA will affect her, hopefully I won't have to sell her .

I get about 12mpg empty and about 9 pulling a gooseneck, so I think you are doing pretty good.

hey 85351ho...what do you think of the side gapped plugs, any power or mileage increases? it seems like an easy enough mod if it works. as far as mileage i get 12 - 15 with my 96 351 e4od ext cab sb with a moon visor, stock tires

 

Believe it or not I have been consistently getting 16mpg since I put my K&N in... even doing 90 mph..

Iv'e got a 91 with a stroked 351 (now a 393) running fuel injection. 38.5 inch tires and 4.88 gears. I get a whole 6mpg lucky me.

 

hey guys I have a 85' F-150 4x4 with a C-6 transmission and a 351W HO. The motor has about 300k miles on it and I have 3.77 gears. Im getting about 10-12mpgs in town and on the highway. Im planning on rebuilding the engine soon so hopefully ill get better mileage.

 

83 F250 2wd with 3.54 rear axle & 8000 miles since being rebuilt -
cruising at 55mph, empty, is giving consistent 16.5mpg(US gals - but I'm in NZ) on open road driving.
AOD trans, but I seldom use OD due to hilly area.
