CNPAPC GM08 Performance HEI Distributor & 9-Wire Kit — Red Cap, 65kV Output for Chevy 4.3L–7.4L V8s

The CNPAPC GM08 Performance HEI Distributor & 9-wire kit is a ready-to-install ignition assembly engineered for small- and big-block Chevy and compatible GM V8 engines, delivering high-voltage spark and complete plug-wire coverage for classic trucks and cars.

This kit bundles a red-cap GM08 HEI distributor with rotor, a matched 9-wire set, plug, and a basic tool kit so you can replace the ignition center and leads in one service. Each unit is computer-tested to meet or exceed OEM output, rated to produce up to 65kV and support engine speeds to 9,000 RPM, making it suitable for restoration projects, performance swaps, and routine ignition upgrades. Fitment covers many Chevy, GMC, Buick, Oldsmobile and Pontiac V8 applications from the 1970s and 1980s — always verify your engine and shaft size before ordering.

Which engines and model years does this distributor fit?

This GM08 HEI is designed for a broad range of GM V8s: small blocks (262–400) and big blocks (402, 454) across 4.3L to 7.4L displacements. Fitment lists common Chevrolet, GMC, Buick, Oldsmobile and Pontiac vehicles spanning mid-1970s through mid-1980s. Use the vehicle compatibility notes and compare shaft size to ensure direct replacement.

• Compatible engines: 4.3L (262), 4.4L (267), 5.0L (305/307), 5.7L (350), 6.6L (400/402), 7.4L (454).
• Covers many Chevy C/K trucks, Blazers, Camaros, Corvettes, Monte Carlos and full-size sedans from 1974–1987.
• Shaft diameter: 12.43 mm — confirm with your rotor shaft measurement.

How easy is it to install and what comes in the package?

The distributor ships with cap and rotor pre-installed and includes a 9-wire plug set, one plug, and a small toolkit to simplify installation. Because the cap, rotor and wires are matched to the distributor, installation typically requires only basic hand tools and timing adjustment to factory specs. No additional ignition module is required when replacing like-for-like HEI units.

• Included: GM08 HEI distributor, red cap and rotor, 9-wire set, plug, tool kit.
• Pre-tested electrically to ensure reliable spark on first start.
• Recommended: check static timing and dwell after installation.

What performance and durability features should I expect?

The GM08 is built to deliver consistent high-voltage output and meet OEM-style timing requirements for older GM V8 engines. Its 65kV rating and 9000 RPM capability indicate the distributor core and cap geometry are intended for both stock and mildly modified engines. Quality control includes computer testing to reduce early failures and give predictable firing under load.

• High-voltage output: rated 65,000 volts for reliable ignition energy.
• RPM support up to 9000 — suitable for performance applications within mechanical limits.
• Cap and rotor included to prevent cross-compatibility wiring mistakes.

Who is this for? The CNPAPC GM08 Performance HEI Distributor & Wire Kit is aimed at DIY mechanics, restorers and hot-rodders working on classic Chevrolet-based V8s and compatible GM platforms who want a single-package ignition replacement. If you’re rebuilding a C10, Camaro, Monte Carlo, Firebird, K-series truck or similar late-'70s/early-'80s GM vehicle and need a direct-replacement style HEI with a matched wire set, this kit simplifies parts sourcing and reduces installation guesswork. Always verify engine displacement, year ranges, and the 12.43 mm shaft diameter to confirm fit before purchase.
