Product Details
Features
- Fits Chevy small block short water pump accessory drive applications

- Standard-drive ratio only — not built for underdrive or overdrive accessory systems
- Chrome-finished steel construction holds up to underhood heat and wear
Description
This crankshaft pulley is machined from steel with a black finish, built for Chevy small block accessory drive systems running a short water pump. It uses a V-belt, 2-groove layout with a 7.300" outside diameter — the dimensions that determine belt routing, accessory spacing, and pulley alignment on a standard-drive small block front end.
The 3-bolt hole pattern is designed for standard-drive applications — not underdrive or overdrive — so accessory RPM stays at factory-style ratios rather than shifting to a modified speed. Before ordering, confirm your engine runs a short water pump rather than long, and check that groove count, belt style, bore size, and pulley offset match your current accessory drive components.
Steel construction with a black finish is built to hold up to underhood heat cycling while keeping a stealth look on the front of the engine. As with any crankshaft pulley swap, verify 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
Verify short vs. long water pump configuration before ordering — this pulley is built for short setups only. Match groove count, belt width, and pulley offset to your existing accessory drive parts, and confirm shaft/bore fit before mounting. Mounting hardware is not included.

Q&A
Does this steel crankshaft pulley work on a long water pump Small Block Chevy?
No. This pulley is designed specifically for short water pump accessory drive configurations. Long water pump setups use different pulley spacing and require a compatible long water pump pulley.
Is this pulley underdrive, overdrive, or standard ratio?
Standard ratio. It's not an underdrive or overdrive design, so it runs your accessories at factory-style speed rather than slowing or speeding them up.
What belt type and groove count does this pulley 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.
What's the outside diameter of this pulley?
7.300" outside diameter with a 3-bolt mounting pattern.
Does this come with a nose cover or mounting bolts?
No. A nose cover and mounting hardware are not included. The pulley is sold individually.
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.
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.
Does this pulley affect emissions compliance?
This is a mechanical accessory drive component and does not directly modify the engine's emissions-control system.

This product does not affect vehicle emissions and is not subject to emissions compliance regulations.
