Dan is right, the place to start is a solid EMS with a feedback loop.
'Swap the intake for a 4bbl manifold, and run a 4150 replacement EFI unit from FAST / MSD / Powerjection III, etc. Run that split 3>1 exhaust header, it scavenges well. Upgrade the ignition to a CD system of some sort."
I already have the Clifford 4bbl set up with a 390 carb. The car gets about 16-mpg while driving like Miss Daisy. I don't know how to mess with the carb to get it right, or the carb it just too big, or likely the engine is just worn out and needs the tweeking that you (generous) guys have suggested. I'm going to go about this real slow but....when I have the /6 freshioned up, that will probably be my only chance to change the transmission if its ever going to get done. I don't want to have to pull the engine twice... unless, of course, I am lucky enough to drive it so much that it needs it. Thanks for the great advice and I will look into the EFI thing! Tom
