Thanks guys for all the advice.

As a short term solution I made the aluminum plate, and plan to drill/tap and plug the intake when I have time to remove it. Or even find one that does not have the EGR path.

After reading a few post on vacuum advanced HEI distributors it is clear that I need to know more about mine. I come by an article by Lars Grimsrud, "SVE Automotive Restoration" that peaked my curiosity. I plan to locate the ID number this weekend and look up the performance specs for it.

What would be a the ideal unit be in terms of pull-in vacuum and max advance angle?

As I mentioned in my earlier post this project is turned into a mess....Oh well that just makes this project a bit longer.

Again thanks,
Gerald
