Small Block Chevy Water Pump Pulley - 6.6" V-Belt For Long Water Pump 350 327 Engines

Chevy Small Block builders and restorers, this billet aluminum water pump pulley is exactly what you need for your engine build! Designed specifically for long water pump applications (that's 7.287 inches from the pulley face to the block for those keeping track), this 6.6-inch diameter pulley fits Chevy 350, 283, 302, 327, 305, and 400 engines perfectly. Made right here in the USA from 6061-T6 billet aluminum, the quality is immediately apparent - the machining is precise, the finish is smooth, and the construction is rock-solid. The single V-belt groove works with standard belt systems, and the 0.625 inch pilot diameter ensures proper alignment. What's really cool is the underdrive ratio - this pulley can actually increase your horsepower by 10-20 HP by reducing the drag on your engine from spinning the water pump at lower RPMs. The design works seamlessly with stock power steering brackets and alternator brackets, so installation is straightforward without needing custom fabrication. The billet aluminum isn't just for looks either - it's significantly stronger than cast pulleys and much lighter, which reduces rotational mass. Whether you're building a performance engine, restoring a classic Chevy, or just upgrading your current setup, this pulley delivers both function and style. The polished aluminum looks fantastic in any engine bay and shows that you pay attention to the details. If you're tired of cheap, poorly-fitting pulleys or want to optimize your engine's performance, this billet aluminum water pump pulley is definitely worth the upgrade. It's one of those components that makes a noticeable difference in both appearance and function!
