Ok guys my Cranking pressure is 160 I tested it with the motor cold I already have the heavy silver springs in the distributor. and the largest bushing to limit the advance. My plugs look good They have a little bit of black on the outer ring ( top of threaded area )the center is tan/borwnish. They are a little wet with fuel but that's probably because I didn't warm it all the way up when I put it away this morning.
