At 65 MPH, I get about 12 MPG. I attribute this to the the higher RPM (2500 compared to 2100 RPM) and to the fact that I am driving a box (wind resistance).

Driver's side pic. Buffalo Steve fabbed on the four bolt plates on this 50's period Edelbrock intake. Note the horseshoe used to negotiate around the rear electric choke. This rod cannot be eliminated as it provides support to the inner and outer fenders and helps to allign the hood. Heat provided to the intake via a home-made plate on the bottom of the Edelbock intake, this plenum was plumbed to the Fentons.

This project could not have been accomplished without the invaluable help of Sweet (who kept me from losing my mind at times, and was there from start to finish) and Grigg III who had constructive suggestions and technical help throughout the project. For more thankyous on the project see the ODSS Homecoming post in the Events Section.

I recently returned from a 1K round trip from Charlottesville, VA to upstate NY and averaged 18.7 mpg at mostly 65-75 mph. So worth the effort.

Yes, 18.7 mpg and I was far from conservative.
