Small Block Distributor Recommendation

Went from bone stock ignition to a full-blown MSD everything and did not gain 1/10 in the quarter mile. In my opinion it was a very expensive rev limiter. My old ignition was the one that came with the Slant six and a brand new $79 parts store distributor. And some Summit brand spark plug wires.
Whoever said that the stock ignition is junk on a Mopar doesn't know what the hell they're talking about...
