With two Holley 94s, and a more progressive cam, the vacuum signal is less than my original Vacuum-only Ford distributor could function with.
So, I got my '60s era V-8 GM point distributor, converted for my '49 Ford engine, from Steve Newsome in Milton, Florida.
It has the vacuum advance deleted, but works perfectly with the new re-calibrated-for-a-flathead centrifugal weights. My engine never started and ran better than now. It cost me $235.
