SBC long Water Pump Alt. Bracket

The SBC long water pump alternator bracket by Alan Grove Components is purpose-built for small-block Chevy engine swaps and custom cooling system configurations where stock mounting won't work. This bracket exists because modern engine bay layouts and aftermarket cooling setups often create clearance conflicts with factory alternator and water pump positioning. Whether you're upgrading to an electric fan, installing a period-correct serpentine belt system, or maximizing radiator placement in a tight engine bay, this bracket solves the geometry problem by repositioning the alternator relative to a longer-stroke water pump pulley arrangement.

Engineered from durable materials to withstand belt tension and engine vibration, the SBC long water pump alternator bracket maintains precise pulley alignment—critical for belt wear and alternator output consistency. The design accommodates the specific offset created by long-pump configurations, which typically add 1.5 to 2 inches of extra length to the water pump body. This extra length requires a different bracket geometry than short-pump setups, and improper spacing leads to belt slip, premature wear, and voltage regulation issues. Alan Grove's engineering ensures correct center-to-center distances between crank, water pump, and alternator pulleys, preserving serpentine belt contact patch and mechanical efficiency across your entire charging and cooling system.

This bracket is essential for enthusiasts building high-flow cooling systems, restomod projects, or engine swaps where long-pump water pumps are preferred for superior coolant circulation. Mechanics and fabricators working on SBC street engines, race builds, and truck conversions rely on this part to eliminate custom bracket fabrication and ensure correct pulley geometry without trial-and-error fitment. Installation is straightforward for anyone with basic automotive mechanical knowledge—simply bolt it in place alongside your long-pump water pump assembly. Verify your specific alternator model and mounting ear configuration before ordering to confirm compatibility with your engine bay layout.
