MAS HEI Distributor & Spark Plug Wire Kit — Red Cap, 65kV Coil & Pigtail for Chevy V8s (283–454)

MAS Racing HEI distributor and spark plug wire combo is a complete replacement ignition kit — red-cap HEI distributor, 65,000-volt coil, and high-performance spark plug wires built for small- and big-block Chevy V8 engines.

This kit replaces worn HEI components on classic and late-model Chevrolet and GMC V8s, offering a direct-fit option designed for common SBC/BBC displacements (283, 302, 307, 327, 350, 396, 400, 402, 427, 454). The packaged set pairs a red-cap HEI distributor with black 90° boots, a high-output 65kV coil rated to 7500 RPM, and a full-length spark plug wire set plus pigtail harness for straightforward installation. Materials and compatibility are targeted at street, restoration, and light-performance applications where an OEM-style fit and modern insulation matter.

What performance and materials are used in the kit?

The distributor uses hardened 20CR steel gears for improved wear resistance and lifespan, while the included coil delivers up to 65,000 volts, compatible with higher-RPM use up to about 7,500 RPM. Spark plug wires have 90° boots to clear engine accessories and provide solid electrical isolation for consistent spark delivery.

• 65kV coil rated for up to 7500 RPM, black housing paired with red distributor cap.
• Distributor gears made from specially treated 20CR steel for durability.
• 90° boots on distributor and plug wires for tight engine bay routing and protection.
• Complete pigtail harness included for OEM-style connections and easier installation.

How easy is installation and what should I prepare?

This is a bolt-in replacement set for most listed applications; basic tools, timing light, and service manual reference are recommended. Installation typically involves removing the old HEI cap and distributor, transferring any needed sensors or weights, connecting the pigtail harness, mounting the coil, routing the wires, and checking timing and dwell per engine spec.

• Requires standard hand tools and a timing light for final adjustment.
• Includes pigtail harness to match factory connectors and simplify wiring.
• Follow OEM timing and torque specs for reliable starting and idle quality.
• One-year limited warranty — contact MAS for support or questions.

Will this kit work for restoration or mild performance upgrades?

The MAS bundle is suited to restoration projects needing period-correct appearance with improved reliability as well as mild performance swaps where a higher-output coil is beneficial. It preserves classic looks with a red distributor cap while providing modern insulation and a robust coil for dependable ignition under increased loads.

• Good for stock to mildly tuned small- and big-block Chevy V8s.
• Keeps classic visual style (red cap) for restored engines.
• Higher-voltage coil supports stronger spark for improved combustion consistency.
• Not intended to replace race-specific multi-spark or CDI systems.

Who is this for: The MAS HEI distributor, coil and spark plug wire combo is targeted at owners restoring classic Chevrolets and GMCs, weekend mechanics refreshing tired ignition systems, and enthusiasts upgrading to a higher-output coil without changing distributor architecture. If you need a direct-fit HEI replacement for common SBC/BBC engines or a complete plug-and-play ignition refresh with one-year coverage, this kit is a practical choice.
