Chevy Small Block Short Water Pump Triple-Groove Steel Crankshaft Pulley - Chrome

• Fits Chevy small block short water pump accessory drive applications

• V-belt, 3-groove steel design, 7.300" OD for multi-accessory front drives

• 3-bolt hub bolts to standard-drive setups without changing accessory ratio

• Chrome-finished steel holds up to underhood heat and belt tension

This crankshaft pulley is machined from steel with a chrome finish, built for Chevy small block accessory drive systems running a short water pump and three separate V-belts. It's a 3-groove pulley with a 7.300" outside diameter — the dimensions that determine belt routing, accessory spacing, and pulley alignment on a front drive running multiple belt-driven accessories, such as an alternator, power steering pump, and A/C compressor each on their own belt.

The 3-bolt hole pattern is built to standard-drive spec — not underdrive or overdrive — so accessories run at factory-style speed rather than a modified ratio. Before ordering, confirm your engine uses a short water pump, and that your accessory drive is set up for three separate V-belts. Match groove count, belt style, bore size, and pulley offset to your current components before installation.

Steel construction with a chrome finish is built to hold up to underhood heat cycling and belt tension while keeping a bright, polished look on the front of the engine. As with any crank pulley swap, verify mounting hardware, shaft fit, and belt alignment before installation.

Applications
Built for Chevy small block short water pump accessory drive systems running three V-belts, including Camaro, Nova, Chevelle, C10/K10 truck platforms, Impala, El Camino, and Monte Carlo applications on a standard-drive setup.

Installation
Confirm short vs. long water pump configuration, and that your accessory drive uses a triple-groove belt layout — this pulley is 3-groove only. Match belt widths and pulley offset to your existing components, and verify shaft/bore fit before mounting. Mounting hardware is not included.

How many belts does this crankshaft pulley run?
This is a 3-groove pulley designed for V-belt accessory drive systems. The three grooves allow multiple accessory belts to be driven from the crankshaft pulley.

Does this pulley work with a long water pump Small Block Chevy?
No. This pulley is designed for short water pump accessory drive configurations only. Long water pump setups use different pulley spacing and require a compatible long water pump pulley.

Is this pulley underdrive, overdrive, or standard ratio?
This is a standard-drive pulley and is not designed specifically as an underdrive or overdrive pulley.

What's the outside diameter of this pulley?
7.300" outside diameter with a 3-bolt mounting pattern.

Will the chrome finish hold up under normal underhood conditions?
The chrome-plated steel construction is designed for automotive accessory drive use. As with any chrome-finished component, proper care can help maintain its appearance and protect against corrosion.

Does this come with mounting hardware or a nose cover?
No. Mounting hardware and a nose cover are not included. The steel pulley is sold individually.

What vehicles commonly use this crankshaft pulley?
It can be used on compatible Small Block Chevy applications such as the Camaro, Nova, Chevelle, C10/K10, Impala, El Camino, and Monte Carlo when equipped with a short water pump and compatible V-belt accessory drive.

Will this pulley affect emissions compliance?
This is a mechanical accessory drive component and does not directly modify the engine's emissions-control system.
