I don’t think you’ll get that out of a 9” behind that motor.


Apparently, I severely underestimated how much of a change in horsepower and (especially) torque that swapping to these parts would make. I knew that they would have an effect on the torque converter, but not to this extent.
At this point, with only a few weeks until the Mopar show in London, Ky, I think that I will just go back to my original plan and put my old stuff back on. Then, sort these other parts out over the winter, and get all my ducks waddling bill to tail feather.
