you might try the type 4rum for engines as it might get a little more traffic to get you an answer.

Those are a lot of expensive parts to trust to a mechanical distributor. Not sure why you'd want to do that when you could make your own advance curve.

Crank-trigger eliminates all of that timing scatter, opens up a few hp, and you will be able to run more advance. It's well worth paying a couple hundred more and spending an extra day learning how to set up a programmable system.
