    Allison AT545 in D300?

    thanks 'cat didn't research the big dana that much. know a guy @ the local salvage yard and he had pulled it from the truck. If I could get the taller gears the size and cool factor (square tubes) would be great. I'm beating the 70HD to death and I have those 'oddball' drums that you can't seem...

    Fluctuating idle ... almost stalling ... almost
