Who is this for: The CNPAPC GM08 kit is targeted at classic GM owners, restorers and DIY mechanics who want a dependable, plug-and-play HEI distributor solution for late‑70s to mid‑80s Chevrolets, GMCs and related GM vehicles. It’s especially suited to projects replacing worn ignition components or upgrading to a higher-voltage HEI setup, but buyers should double-check rotor orientation and shaft size against their engine and model year before ordering.
