If you don't have any distributor stuff, I would run the COP setup with a 24x wheel not the 3 pulse/revolution setup.

I agree. The 3 pulse per revolution is not adequate.
I have to disagree with the cam sync having 'no' effect on spark timing accuracy.
A high res, crank mounted timing wheel with the sync built into the crank wheel can't be beat.
