MSD Blaster 2 Coil question

The coil used should match the type of electronic ignition you're using. I've mismatched coils on my Ford race engine with a Pertronix ignitor and the results were a burned up module in the distributor. And one of the coils that burned it up was a Blaster 2. As Mattax said, match the coil to the ignition system you're using.
