What gears do you have? What transmission? Any mods to the motor?

With my setup im getting between 10 and 12 mpg.

1979 F150 Custom 2wd C4 302 painted ford blue, bored .040 over, flat top pistons with valve reliefs, Edelbrock Performer cam, carb, and intake, stock heads til next spring, MSD Ready-To-Run distributor, MSD Blaster 2 coil, Edelbrock air cleaner and valve covers, Dynomax headers, dual exhaust with Flowmaster 40 Series mufflers, 38 gallon fuel tank(how i can drive it further than around the block) 9" rear end with 2.75 gears and open diff to change to 3.50s and locker next spring.

Belive it or not that is about right on the money. I get about 11 mpg. I only have an intake, carb, and ignition that is aftermarket. A few of my friends get roughly the same milage. Some only get 8 mpg. But what do you expect with a Holley 750 and a Edelbrock Jr. intake and so on.

 

I have a 84 van with a 302. The motor is bored 40 over. It's got dished pistons in it, stock heads, a holley intake with 1 inch torque spacer. And an Elderbrock 600 with electric choke. It also has mustang shorty headers and true dual eghaust. It has a C6 tranny. It gets 17 miles per gallon on the highway.

 

hey,
i honestly do not know what transmission i have, its an automatic with 1 2 and drive, no overdrive. 10-12 is my highway and town mileage, i havent ever had it change. i don't know what geras i have either. no engine mods, just replaced plugs, air filter and etc, all with stock parts. i've got dual exhaust, which i am replacing this spring, its got several holes and is rusted out for the most part. thanks for all the input!

Mine runs at 16mpg.

 

Mike, I had the same problem in my '83 f-150 4x4. I got 10 miles to the gallon no matter how easy I drove it. My exhaust was shot, too. I had the cat replaced along with the muffler because it was "stopped up" and my mileage jumped to 12 mpg! That's still running it through single stock exhaust! I imagine yours would go higher since it's two-wheel drive. Try that and good luck!

thanks for the ideas, i hope the new exhaust helps a little, do those K&N hi preformance filters really do all they say they will? like the change in gas mileage and horsepower?
