First to answer Dave take a look at the specs for a much better streamlined
1977 Z28 Camaro which has a similar driveline to my roadster:

1977 Camaro data - Statistics, facts, decoding, figures & reference information

Even the better streamlined body of the Z28 only got 17 mpg on the highway.

Next to answer Roger I did the chalk line test again with 28 psi in the rear and 30 psi in the front. This time I used only 3.704 gallons on the usual 63 mile circuit to and from Bowling Green VA. (63 miles/3.704 gal) = 17.00864 mpg! I guess that is all I can expect since the better streamlined Z28 body only got 17 mpg with a similar driveline to my SBC 350, 700R4 and 3.55 rear gear so I plan to keep using the 30/28 tire pressures from now on. I note the ride is better at 55 mph and keeping the speed at or below 60 mph probably helps increase the mpg as well as the improved tire pressures.

Can anyone please tell me how to flush the 20 pictures I have accumulated in "Manage Attachments"? At present I am unable to submit pictures since the buffer is limited to 20.
