Re: gas mileage

I have a 400 sbc and I get about 5 average. On the highway if I keep my foot out of it I can squeeze 9-10 out of her. I have 35" tires and 4.10s currently. Can't wait to put my 4.56 gears in her
I also have a TH400 tranny and no overdrive. When I have the 700R4 and the 400sbc I got about 10mpg. Generally off-roading I measure it in Gallons Per Mile

Re: gas mileage

How about some specifics? What kind of truck do you want to know about? Do a search for this (on both the SFA and IFS boards) and you will definately get a bunch of answers. 95 K2500 350/NV4500/3.73's/33" tires 13-15mpg city, up to 18 on the highway going 60-65mph. 13 or so going 80.

Re: gas mileage

10-12 city. 350/700R4 and 2.73 gears with 31" tires. I can get 16-17mpg on the highway if I keep it between 55 and 63mph in overdrive.

Every time the secondaries open I lose a needle's worth of fuel.
