What I think Idaho might be missing is that there's far more to it than just drilling holes.
The 5.9 wheel has the holes clocked the same as a 360, and I think they're the same radius from the crank center, they're just smaller holes.
To be fair, it's way simper just to build a crank trigger and run it off the front of the motor. 8 slots, evenly spaced, is 8 slots evenly spaced, no matter where they are.
