The Distributor Gear - Chevy V8 .491in Melonized is a precision-engineered component designed for classic and modern small-block Chevrolet V8 engines requiring exact timing control and reliable distributor operation. This OEM Chevrolet Performance gear is essential for builders and restorers who demand authentic, factory-specification parts for engine assembly, rebuild, or high-performance modifications.
Manufactured to Chevrolet Performance specifications (MPN 19432310), this distributor gear features melonized steel construction—a specialized hardening process that provides superior wear resistance and corrosion protection compared to standard cast iron alternatives. The .491-inch bore diameter is precisely machined to fit Chevy small-block cam bushings and distributor shafts without play, critical for maintaining ignition timing accuracy and preventing drift over thousands of miles.
This gear is ideal for enthusiasts rebuilding vintage Chevy engines, street-performance builds, or restoring original-specification powerplants where OEM parts are required. Its melonized finish extends component lifespan under continuous cam-lobe contact, making it particularly beneficial for high-RPM or extended-duration cam applications.
