Re: Fuel efficiency...what MPG do you get?

1975 C20 long bed with clamp shelf.
Engine 350 with a mild RV cam, TBI and custom real time tuning (highway lean cruise not enabled, yet)
Transmission 700R4 with stock converter (about 1400 RPM)
Rear end 4:10 with 33 inch tires

Highway about 17 mpg, city 13 mpg. Previously, before converting to EFI with Q-Jet i was getting 12 mpg on highway and 9 in city.
