67 Sunbeam aero mods

The Sunbeam is a small car and the 2.3 I built for torque makes HP/TQ at much lower RPM than the original engine. Taller tires also slow down the engine, and along with a .75 Overdrive with a lockup converter, that also slows down the engine. I plan to replace the "Eyebrow" headlight rims with smooth ones, fab an air dam for the lower valance, keep all under carriage stuff out of the air stream, keep tires inside the body, use small aero outside mirrors (it is a driver), and run the removable hardtop 90% of the time. I am practical and understand SUPER MPG is not my goal but very good MPG in a car that can be driven any time anywhere. My eye doc says I may have to turn in my drivers license in 2 to 4 years (Macular Degeneration/Glaucoma) so finishing it next summer is my goal. At 77 I do not work as fast as in my younger days but I think I can do it. That will give me a year or two to test my build and see some of the US I have not yet seen.
