Reviving a Mustang GT’s ignition system with MSD Super Conductor wires, Blaster coil, distributor cap, and rotor ...

Ignition was handled by an MSD Pro Billet distributor, Extreme Duty 6ALN ignition box, and High Vibration Blaster Coil, which supplied plenty of spark (or so we thought-more on that later).

Fortunately, MSD now offers the Pro Billet LT1 distributor, a comprehensively upgraded OptiSpark unit designed to fit all LT1- and LT4-powered Corvettes.

Ignition misfires can be confused with fuel mixture or delivery problems. Even ambient humidity can affect the ignition system—making a misfire’s symptoms seem random and difficult to pinpoint.
