K here's my problem. I want to connect 2 hemis together crank to crank. Problem being these cranks do not have a key way. How or who makes a blower hub to fit theses or does a guy have to pull crank and cut keyways.
Dunno what they use now but in the old days, the smart guys (R.C. Williams, John Peters, just to name two) used "Couplers" . . the same thing you use on a dragster with a solid rear end instead of a U-Joint.
