Small Block Chevy Double Hump Heads 305 327 350 383 5.0L 5.7L
In SBC engines with double hump heads, the alternator and power steering pump are essential components, responsible for the vehicle's electrical power supply and steering assist. Since double hump heads lack mounting holes for modern accessories, specially designed brackets are required to install and secure these parts, ensuring they align properly and work seamlessly with the modified system.
Installation Instructions: Generally, only basic hand tools and some mechanical knowledge are required to complete the installation. ? ? ? ?

The SBC Alternator/Power Steering Pump Accessory Drive Bracket Kit is essential for SBC engines with double hump heads. It not only addresses the structural issue of these classic cylinder heads lacking mounting holes for modern accessories but also ensures the proper installation of components and alignment of the drive system. This improves the engine's reliability and driving experience. For classic car restoration and modification projects, or any situation requiring an upgrade of SBC engine components, this kit is indispensable.
