Only runs 40 Degrees advanced

Wow, it always is the simple things that come up to bite you. That reminds me of my kitchen table re-curve when I put the reluctor in upside down (like for a big block) by accident. I had a spare distributor handy so I was able to correct it quickly, but it wouldn't run for crap either. I haven't been able to run an MSD yet, so I will keep this in mind!
