Something different Building for MPG.

/6 with a 4 speed OD trans and 3.23's in a really lite A.

Ditto, E or DFI'd /6 with a modified 4-spd OD trans, 2.73s in a Featherlite Duster along with that new aftermarket setup that you manually switch on to cut the fuel to 50% of your cylinders when at cruising speed. I really need to read up on that. It is being developed by a group of investors in SoCal. I know that the technology is all ready being utilized but this is an aftermarket piece for the masses ... supposedly.
