The thing with points ignition when there are 8 plugs to fire, the coil has to build up charge between each cap contact so the time is limited and when you build up revs there is less time for the coil to build up charge, so the voltage to each plug will decrease. The points cam follower whether its plastic or fibre wears and the points gap will become smaller as well after time.
I use an MSD ignition with blaster 2 Coil on my 347 stroker and it starts as fast as the key is thrown, has no issues at all and stays in tune. Street use only.
It s all about dollars and performance IMO.
While working on a 6cyl, stroked BMW which we race,we tossed the electronic distributor and single coil away and installed a GM triple coil pack and crank sensor and reconfigured the computer to suit. Brilliant result for that car which is limited to 7400 RPM. It burns lots of E85 so you need a good spark for the extra volume of fuel going through.
