The Power Grid Kit also includes an MSD 6AL2 ignition module that provides precise control over the ignition system. The module is adjustable for both timing and advance, allowing you to fine-tune the ignition system to optimize performance for your specific engine configuration.

The kit also includes an MSD 8.5mm coil harness that connects the ignition coil to the ignition module and distributor. This harness is made with heavy-duty, high-temperature wiring to ensure reliable power delivery and long-lasting performance.

The MSD Ignition 77303K1 Power Grid Kit is a comprehensive ignition system upgrade for Chevy Big Block engines that delivers reliable ignition, improved performance, and increased power. It is built to the highest standards of quality and durability, making it an excellent choice for any serious performance enthusiast.
