Re: Which MSD pro billet should I go for?
I have (on the shelf) an Accel HEI that I bought 10 years ago to replace the point distributor. Ran great until I took it out because it didn't clear the fuel rails on my MPFI. Replaced it with the MSD std "Pro Billet" vacuum advance distributor and a 6A box I had laying around. Ran perfectly for 3 years until it was taken out and replaced with the MSD small cap "Pro Billet" non-vacuum advance to clear the fuel rails on my stack injection. All of them have done what they were designed to do with no issues. For simplicity, go with the HEI. For special applications use the others requiring a stand alone coil.
