Just drove to memphis and broke it up into 4 parts.

100 miles at 65 I got 29 mpg twice.

100 miles at 75-80 I gon 25 mpg

the 4th 100 mile trip was cut short when a brand new U-joint broke

I did put on the electronic ignition before leaving and hooked up the vacume advance witch definately was helping. It was a lot easier to maintain a steady speed and was more responsive when I was cruising and needed to go up a hill. Idle smoothed out like glass with the electronic ign.

It does definately want another gear (OD)in the tranny, it is turning nearly 3000 at 80.
