MSD6AL ignition - This was added for several reasons.  The multi-spark ignition feature should help the car perform better.  The rev limiter will help avoid potential problems during hard acceleration, particularly if I do manual shifts.

Coil - MSD Blaster 2 cloil, part number 8202

Distributor - Mallory Billet Competition distributor - Series number 84. DIST, CHEV V8 MP 208M CAP, part # 3248201

The distributor curve was set up by Bruces speed shop. The initial timing is 18 degrees

This distributor cannot be used with just a coil. It requires the use of a capacitive discharge ignition system.

This must be used with suppression type wires (carbon core, suppression core, spiral core, etc.)
