I have a 351 Windsor in my 1986 Ford F 250, but my gas gauges don`t work, Therefore I cant really keep track of my MPGs. I don`t know much about my Carb other than its an Edelbrock 4 barrel with a manual choke. The truck is a 4 speed granny low and has 3.50 gears. It is the over 8500 GVWR. Also an HO motor. What gas mileage should I expect to get? And does anyone know where I can get replacement sending units? Several parts stores near me dont carry them. Thanks

 

If it's tuned up and you are easy with it(stay around 55mph) you might squeeze 15mpg of it(if you have stock tires).

If you have big tires, and drive 70mph all the time, you will probably get 10mpg out of it.

 

i wanna sell it but cant seem to get any interest

 

LMC have the various sender units. Four years ago I bought two from Ford.
