Mine did average 17 mpg on a 900 miles trip. Was doing round 60 most of the time. Rpm was close to 2000. 350/265, now with a q-jet TH350 and 2,78 rears with 225/70-14 rubber.
Feels a little high. Might look into that in the future..... :rolleyes:
But .....it really doesn´t matter too much; it won´t be driven too much up here. And gas is some 6.50 bucks a gallon!!!
