When everything is proper mechanically you should expect between 20 and 25 MPG running up to 60 MPH.

This is based on the operation of properly restored cars to most Ford factory.

In one case my brothers 31 coupe averaged like 23 MPG on a trip from NJ to WI. That was an overall based on miles driven and gas input. The speedo was showing 55 to 60 most of the way out and back. But we found out later with GPS it reads low by about 5 MPH.

When I did a check of the 40 to 50 jets from the carbs we have I found most were flowing too much. But there are so many things that affect performance. Poor engine balance, used cams, improper valve setup, not properly setting timing and so one that cause poor fuel economy.

Please do not feel bad about your car. Most people do not understand the A driveline is actually a precsion built unit for the most part. If you take Ford prints to a machine shop they will tell you that you are trying to build a race car.

In the end to build the A properly (not JS correct) it is not cheap , easy or fast to do.
