Get this - my daily is an 87 GMC 1-ton, 292 6cyl, non-OD 4sp, 4.56:1 rear gears. Obviously, I rarely drive it out of town, though on a recent highway trip (it won't do more than 55 mph), it pulled down 14 mpg. I'm attributing the mileage to keeping my speed down (dump trucks were passing me like Vipers). The 292's great torque helped, obviously. What a V-8 would have pulled down in the same situation, I have no idea, but I bet I'd not have had dump trucks passing me.

My family had a handfull of 70's Chevy 1/2 ton 4X4 pickups. Every bloody one ot them got a solid 10mpg when bought. We always installed headers/duals [they were 49 state noncat trucks] and a part time 4X4 kit. The winner for mpg after these mods turned out to be the truck with 3:73's and 235/75/15 tires. It would get 13.5 mpg highway. The 3:42 geared truck improved to 12 mpg with the same size tires. The loser was the 3:07 or :08 geared trucks! They still got 10mpg, but seemed to run better! This was before OD trans, so that 3:73 truck would scream on the highway! It didn't hurt the mileage though. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 " I was different before people dared to be different" _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
