Mechanical Advance


F-Bird'88, you are correct, budgets must be maintained!! I'll look into contuing with my unit and using your your picture and notes to fabricate a stop.
Is there a particular machine screw size/type you go with that I could start with? Or am I looking at putting it in, testing, then shaving it down some, testing, shave some more, test, etc. etc.

The VAC advance on my unit is NOT adjustable. I guess it used to be (based on the 2 different user guides for 8362 I found out there) and when I called MSD they indicated that, Yes, they changed their street-fire "value brand" to no longer have an adjustable can but they do include the vacuum advance stop plate. (see attached picture).
The MSD tech also indicated that the vacuum advance can with this unit will go all the way up to 22 degrees advance. It kicks in at 5 hg and goes up linearly, based on Hg, to the max of 22 degrees. The stop plate willl stop it at that range listed for the letter selected.
When I pull the distributor out I will also be installing that stop plate and I am going to set it at the B (11-14 degrees stop) so as not to exceed 15.

Also, I read a bit up on Phasing alignment but did not think it would matter to me as I have a brand new distributor so everything should be smooth and work great. Is there some sort of test I can do to ensure there is no phasing problems?

cdminter59, no box, just the streetfire GM HEI with incorporated coil.
