Distributor Questions
HEI & MSD ready to run are both inductive ignitions. The HEI style cap has better positive plug wire retention.
Why go with a mallory coil and not a matching MSD coil? Get a matching blaster 2 coil.
The MSD distributor and coil are a good setup.
Remember to read up and set up the distributor advance bushing/advance springs before you install it.
