BBC Electric W/P Alt. Bracket

The BBC Electric W/P Alt. Bracket from Alan Grove Components is a purpose-built alternator mounting solution designed for Big Block Chevy engines equipped with electric water pump systems. This mid-mount passenger-side bracket addresses a critical challenge faced by engine builders and hot rod enthusiasts: integrating modern electric cooling technology while maintaining reliable alternator positioning and belt alignment. Built for those upgrading to electric water pumps for improved engine bay thermal management and efficiency, this bracket ensures proper serpentine belt tension and alternator output without modification to core engine components.

Constructed from steel in natural finish, the BBC Electric W/P Alt. Bracket mounts directly to the cylinder head and water pump mounting points, providing a rigid, vibration-resistant platform for GM-style alternators. The mid-mount design centers the alternator's load path, reducing stress on engine block ears and extending alternator longevity in high-performance applications. Steel construction ensures durability under thermal cycling and engine bay vibration typical of modified engines, while the head and water pump mounting interface integrates seamlessly with factory-style mounting surfaces. Weighing only 2.34 lbs, the compact design (7.45 x 1 x 8.9 in) fits tight engine compartments without compromising serviceability or hose routing around the water pump.

This bracket is ideal for Big Block Chevy engine builds—particularly LS swaps, classic muscle car restorations, and street/strip applications where electric water pump cooling is preferred over mechanical systems. Installation requires no extensive engine modifications; the head and water pump mounting points are factory-standard on BBC engines, making this a bolt-on upgrade for engine builders prioritizing clean bay layouts and modern cooling technology. Compatibility with aftermarket alternators (particularly GM applications) and standard serpentine belt systems makes the BBC Electric W/P Alt. Bracket a reliable choice for professional builders and experienced enthusiasts seeking plug-and-play alternator mounting without custom fabrication.
