17 MPG..??
Damn ...i'd kill to get that in my 51 truck with 5.7 350. TBI ...700R4 .... NP208.......91 suburban axles...3.42 gear ratio.....right now i see bout 10 in the city and 12 on the highway...been told the SBC...were supposedly good for at least 15 in town and 17 on the highway....be Damned if i ever get close to see that......
i mean with the 3.42 gears and the 700R4 overdrive ..turning 2500 rpm at 70......i would think i could do better then i am.....however i am running larger 33' tires so that has to be a factor in it somewhere.....piss poor mileage is main reason i am going to install a larger 30+ gallon tank to increase fuel range...this stopping every 150 miles..( .Full to Empty) for fuel is pure B.S....hoping to do this after the First or so and in plenty of time ahead of Moab this year....Maybe..??........I Hope..!!
