Well 9-10 MPG doesn't realy scare me that much...but 3.5-4 sure would. However I don't think the caddy 500 would do much better than the 9-10 mph. I guess thats just the price you pay for having all that power on tap. With a newer carb and a 2:1 OD I should realy be able to improve on the 9-10 MPG while not towing.
Thanks for the info

EDIT: Will the stock distributer handle a hotter coil or will I need something newer? I remember there was some info on 6066 about a newer upgrade.
