Chevy Small Block Short Water Pump Double-Groove Aluminum Crankshaft Pulley - Black

• Fits Chevy small block short water pump accessory drive applications

• V-belt, 2-groove design, 6.600" OD for stock-style belt routing

• 3-bolt aluminum hub simplifies standard-drive install and alignment

• Black-finished aluminum resists corrosion for a clean front-drive look

Built for Chevy small block accessory drive systems running a short water pump, this crankshaft pulley is machined from aluminum with a V-belt, 2-groove design and a 6.600" outside diameter. Those dimensions are the reference points for matching belt routing, accessory spacing, and pulley alignment on a standard-drive small block setup.

The 3-bolt hole pattern is built to standard-drive spec — not underdrive or overdrive — so it's intended for engines running a factory-style accessory drive ratio. Before ordering, confirm your engine uses a short water pump (versus long), and match groove count, belt style, bore size, and pulley offset to your current accessory drive components.

The aluminum body carries a black finish, giving it corrosion resistance and a clean, non-reflective look under the hood — a common choice for small block Chevy builds where a finished, factory-style appearance matters as much as function. As with any accessory drive component, confirm mounting hardware, shaft fit, and belt alignment before installation.

Applications
Built for Chevy small block short water pump accessory drive systems, including Camaro, Nova, Chevelle, C10/K10 truck platforms, Impala, El Camino, and Monte Carlo applications running a standard-drive (non-underdrive, non-overdrive) setup.

Installation
Confirm short vs. long water pump configuration first — this pulley is built for short setups only. Match groove count, belt width, and pulley offset to your existing accessory drive components, and verify shaft/bore fit before mounting. Mounting hardware is not included.

Will 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 an underdrive or overdrive pulley?
Neither. This is a standard-drive crankshaft pulley and is not designed specifically as an underdrive or overdrive pulley.

How many belt grooves does this pulley have, and what belt type does it use?
This pulley has 2 grooves and is designed for V-belt accessory drive systems. Verify that the groove count and belt alignment match your other accessory drive components.

Does this pulley come with mounting hardware or a nose cover?
No. Mounting hardware and a nose cover are not included. The pulley is sold individually and uses a 3-bolt mounting pattern.

What's the outside diameter of this crankshaft pulley?
6.600" outside diameter.

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

What vehicles is this crankshaft pulley commonly used on?
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.
