MAS Racing HEI Distributor and Spark Plug Wires Combo Kit - Red Cap

In this review the MAS Racing HEI Distributor and spark plug wires combo is judged as a practical, no-nonsense replacement for older Chevrolet small block and big block V8s. The kit is aimed at owners of 283, 302, 307, 327, 350 and 400 small blocks and 396, 402, 427, 454 big blocks who need a complete ignition refresh; the single biggest reason to buy is that it bundles a red-cap HEI distributor with a full set of spark plug wires and a free pigtail harness so a tired ignition system can be returned to reliable operation in one go.

Key Features

• Complete combo: The kit includes a red-cap HEI distributor, spark plug wires and a pigtail harness so installers get everything needed to fire the engine without sourcing separate parts.
• Wide vehicle fitment: It is compatible with a long list of Chevrolet and GMC models, covering trucks, vans and cars that use small block and big block Chevy engines for straightforward fitment guidance.
• High-voltage coil support: Designed for a 65,000 volt super coil and up to 7,500 RPM operation, which suits performance-tuned SBC and BBC applications where robust spark energy is required.
• Durable gears: The distributor uses specially treated 20CR steel gears that are hard and wear-resistant, aimed at improving longevity under repeated use.
• Practical boots: Black 90 degree boots on both the distributor and spark plug ends help achieve a tidy, routed installation in tight engine bays.

Who It's For

This combo is best for classic Chevy and GMC owners doing a mid-level restoration or ignition upgrade on small block and big block V8s who want a single kit that restores distributor function and replaces aged wires. It suits home mechanics and professional shops that value fitment coverage across Bel Air, C10, Camaro, Corvette and many other Chevy/GMC platforms.

Those who should look elsewhere include builders needing billet or high-end racing distributors with adjustable advance curves or integrated electronic control modules; this kit is a practical replacement rather than a race-only exotic, so extreme track-focused teams may prefer purpose-built race components.
