Sorry 626. The lack of availability of such a common part as a disrtibutor cap is not something most have to deal with. The snap sound is the sound of the spark arc finding ground elsewhere when the plug wire is removed. This is certainly a common and normal sound for 12 v cars and resistor wires making 15000 or 20000 volt secondary voltage. As far as some wires seemingly producing a louder spark- could be a weaker/ stronger coil as you suggest but could be due to longer dwell and saturation from varying point dwell caused by worn lobes or shaft bushings. We could get into a long discussion about saturation/ dwell/ 4 lobe vs 8/ primary voltage / and rpm . Im sure it has already been hashed out here in previous threads. Surely this was the theory behind 4 lobe twin point / coil systems with a 6 v system. Later 8 lobe dual point v8 used overlap of the second point set to increase saturation and control contact bounce. Let me ask-#3 and #6 fired by the same lobe but on opposite point set?
