Use one of these on your Distribter shaft.i used one on my 440 and it helped a bunch. It takes the slop out between the oil pump drive and the Dist tang.

Caution on using an 1/2 set collar for the spacer.
Most Mopar distributor shaft are not a 1/2" in diameter where the spacer get locked down. Mopar shafts are generally .4885 in diameter.
Better to bore out a piece of 1 1/4" round aluminum stock or use a 7/16 collar a bore it to size.
Rick Ehrenberg sells the correctly bored spacer as well.
