The last is a good sign of a denect spark system. Having said that, and HEI will out-spark an MSD. MSD just uses a capacitive discharge system with a the feature of multiple firings at low RPM's. But the Blaster 2 coil you are using limits the charging current to about half of that in an HEI coil, and so the spark will consequently have less energy. This WILL make a difference in certain firing conditions; higher compression ratio will make the spark energy more critical to get a good spark kernal started.
