Hi, I got my new HEI for my 200 from was111 on this site. We discussed the engine, gears, and about my Bronco, it is a lot heavier than a Falcon. Then he set up a high quality HEI for me.
I would not run the cheapest distributor I could find. I feel my new HEI could last forever.
The distributor works great, I am very happy with it.
Wsa111 also works on Ford Duraspark ignitions, which are very good.
Good luck
