Moroso Chevrolet Small Block (w/Short Pump) Crankshaft Pulley - Single Groove - Cast Aluminum

This is a single-groove crankshaft pulley from Moroso, made specifically for Chevrolet small block engines that use a short water pump. It's constructed from cast aluminum, which helps keep the rotating mass down compared to heavier steel or iron pulleys. A lighter pulley can contribute to slightly improved engine response.

Moroso has been making performance engine parts for a long time, and this pulley is a well-built piece designed to fit right onto your existing setup. The single groove is intended for a single accessory belt, commonly used on race cars or simpler street applications where you might only be running an alternator or a water pump. Make sure your engine uses a short water pump before ordering, as this pulley is designed to work with that specific configuration.
