How do you Convert HEI to Mopar

Yes, but not nec what the book says.

There is a procedure for establishing optimal initial timing using a vacuum guage. Then the dizzy needs to be modified to limit the total advance.

There are several threads on the subject.

Once established, the initial timing is correct for all ignition systems.

I understand the procedure for setting initial timing and limiting mechanical advance to achieve optimal total timing. I was just curious if the initial timing was the same for both videos? Did the ignitions change what the engine wanted for initial timing at all?
