I have a 350 with stock compression, a mild cam, 194 heads, q-jet, K&N air cleaner, MSD 6a, curved dist with adj vac adv, performer intake, Z28 oil pan with windage tray (worth a few HP and wee bit of fuel economy), Clutch fan, rams horns with 2" duals running turbo mufflers and I have a turbo 350 with a 3.73 rear end. I get about 12.5 MPG (US gallons) at 70 MPH. I also get the same at 65 towing an unloaded 2500 lb flat deck and about 10 hauling the same trailer loaded with half a truck. Not sure what I'd get at 60 but it would probably be about 13 or 14 MPG. A 3.08 would really help on unloaded cruising as would a 700 R4. Hope this helps.
