6x6 Tech

[ChevyKev]

... I think if I had a big block gasser with 42's it would be more like 5-6 mpg.

Possibly - in that heavy of a beast... However, in my Borther's carb'd 454 Blazer he gets 11 on the road - granted that is with 36's, not 42's.

I get 12 with a carb'd 350 and 38.5's and 4.88's

I know fuel injected rigs with 454's that get better fuel economy than with mine

However, with 6 42's ... I don't know anything will get great mileage as well, he will have the room for extra fuel... so this may be a mute point.
(kinda wish I would have thought about that before I typed all the above.)
