Thank you very much for your time in posting all of this very helpful information.
I have a 1976 304 and I plan to upgrade using option 3.
I have a few questions:
1) What MSD CDI module to you most recommend as most reliable/best performing?
2) How do I know where to locate the notch in the distributor? I see the pictures, but there are no dimensions, is the location very critical or can it be ±2°?
Thanks again for taking the time to educate us all.
