Key Features:

Bracketless Design: Timing cover is integrated into the bracket/casting for simplified assembly and a clean appearance
Holley Premium 150 Amp Alternator: High-output alternator provides plenty of power for modern vehicle electrical systems with easy wiring that doesn't require factory ECU excitation
SD7 A/C Compressor: Compact, efficient air conditioning compressor for effective climate control
Type II Power Steering Pump: Features baffled reservoir for consistent performance under all driving conditions
Holley Cartridge Water Pump: Compact design allows easy servicing without removing the water pump housing or timing cover
OE-Style Harmonic Damper: Includes cast-in serpentine pulley with original equipment pulley ratios for optimal accessory performance
Flexible Plumbing Options: Swivel water inlet and outlet allow custom radiator hose routing; configurable heater hose connections provide maximum hose routing flexibility
Complete Installation Kit: All necessary plumbing adapters, wiring adapters, gaskets, and seals included—no additional adapters or spacers needed
Wide Compatibility: Works with common aftermarket and factory throttle bodies and intake manifolds

This complete accessory system is finished in a sleek black coating and provides everything needed for a professional, hassle-free installation. Ideal for engine swaps, resto-mods, and custom builds requiring a reliable, high-performance accessory drive solution.
