I got 17.75 around town the other day. 350 GM TBI replacement engine,electric fan,Edelbrock Performer TBI intake, mid length headers,daul exhaust, 32X11.50 15 BF Goodrich All Terrains, 3.42 gears, 5 speed.
I have gotten over 19 on the highway with half wore out mud terrains. I can see 20-22 on the highway fairly easily once I put on a new header gasket
