Have a 270 that runs sweet as can be, but I only pull about 9mpg empty. Havin really low gears in the rear end doesn't help my mileage, but at over 9,000 lbs dry weight there's a definite difference between too much gear and not enough to do the job, so there's a trade off.


1956 GMC 370 dump " 'Tater "
1970 VW Volksrod "the Black Bomber"
2007 Chevy Avalanche
2020 Jeep Cherokee Trailhawk,
2005 Harley Davidson FLHTCUI

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion!
