Forgive my off topic, but,

Sure would like to see a dyno on that

75 HP? More?
Sweet specs




Bucky, Performance Mods, Dyno Results Table, Page 4 has Mag10's dyno run......pretty impressive. 80hp

Michael, sorry for the off-topic conversation....coils can become intermittent. Not likely but they can. The more likely is a dicey connection to the coil hot or ground leads.
Spark plug wires should be checked too.
