I never had a real issue with the cam sync. I just cut off all of the teeth on the dis except for #1, made sure to stab the dist. with the rotor pointed exactly at #1 on the cap with the crank at 10* btdc, then set the crank sensor at 60* btdc. The black wire from the hall effect sensor (on a MSD TFI Pro Billet Dist) goes to ground, the red wire is the key on power (12volt pass through wire on a Fast XFI) and the green wire went to the Cam signal wire. Had to loop a couple of other wires in the harness as it was not set up for a discreet hall like the TFI dist. but all in all not to bad to do once I got my mind wrapped around it. Engine fired and ran right off, verified commanded timing with the laptop, and that was it, other than the actual tuning.
