Gas Mileage

[Backwoods]

Maybe this is a mute point, but I am going to try anyhow, I have a 79 F150 4wd, with a 400 4 speed, and am getting 9 mgp out of it, is this normal, or is there any tips or tricks to better gas mileage, and if I am stuck with 9 mpg, I might put in a 460 to have more power, I figure, it would probably do 9 anyhow.???

9-12 is normal for these trucks. Depends on the tires and how hard they are driven. I could get about 11 with mine on the highway to as low as 6 when pulling a heavy load.

With after market intake holley carb ,cleaned up heads and headers I could get 12 MPG .

Never broke 10 on a pre 90s 460

There must be some alternative to be able to get mileage out of one of these, how about installing a holley throttle body with a msd ignition, whatdya think?

I think it's still a heavy brick, that cuts through the wind like a barn door.............


Seriously though, I couldn't tell you what my 79 gets for mileage. I've never checked it. All I know is that it's a blast to drive!

Taking into consideration for the type of driving you've been doing in your '79,
I'd say it would probably be easier to calculate in Gallons Per Hour

I'll take that as a compliment! Thanks Mark!!!!

Keep your foot out of it is about all that can help it.

8.5mpg with a 4,000 cabover camper on back. 10-11.5 empty with my 460, 3:73 HDdana70 rear diff. Can't imagine ever getting anything better than that.

My 79 gets 5 to the gallon its just a heavy old truck i dont expect to get much better than 5.
