Supposedly there is talk of this one having the next gen allison with 8 or 9 forward speeds. The allison has been the limiting factor with the new l5p engine, if they get a better trans it will be interesting to see what GM does in the HP war. The L5P has ALOT of potential with everything GM did to beef up the bottom end, and the heads can move some SERIOUS air.
