If it fires all the plugs, all the time at the right time, then there's no advantage either way. Some are easier to work on then others, but there isn't really a huge difference there.
Practically any distributor in good shape can get the job done, there is more of a difference in what kind of ignition amplifier you use, than there is in the distributor itself. Pick one that has features you like, and one that's compatible with your amplifier, and go for it. Most of the time, they will need to be tinkered with (advance curve) to work the way you want them to anyway. |

The big question is, if you are having crossfire problems because your aftermarket coil is putting out 60k volts. Then, you could take advantage of the MSD billet dist that has a wide body to keep the wires separated a bit on the cap. Other than that, I found the MP dist to be very stable and easy to work. It isn't as sensitive as the Mallory, which sometimes had "conniptions" and caused intermittent backfires. Make sure you use a dial back timing light and pinch off the vacuum advance when you set total timing. (should be about 32-35 degrees for hp motors). If it starts and idles well after that, you're almost in heaven. Then, check to see that all your advance is in by 2500rpm. The vacuum advance does'nt really affect performance, just cleans the plugs. If you want more, MSD and others sell electronic modules that plug in between the dist and the coil, and you can tune from there. MP even sells one tailor made for their unit.

My 446 ci has the MP w/mech tach drive and has worked great.
My 528 ci has MSD pro billet and it works great also. I like the MSD because of the buttons & springs for diff total advance and rate of advance. |
