Block Adapter Kit SBC 12AN

The ALLSTAR PERFORMANCE Block Adapter Kit SBC 12AN is a small-block Chevy water pump adapter designed to transition cooling systems from standard to remote configurations using 12 AN male ports. Manufactured from aluminum and finished in black anodized coating, this kit enables builders to relocate water pump mounting positions while maintaining reliable coolant flow in high-performance and custom engine builds.

The 12 AN male port configuration provides industry-standard hose coupling compatibility, allowing seamless integration with modern cooling system plumbing in street rods, race cars, and engine swaps. Black anodized aluminum construction resists corrosion while remaining lightweight—critical in applications where cooling efficiency and minimal parasitic weight matter. The adapter kit preserves OEM cooling capacity while permitting custom engine bay layouts that would otherwise be impossible with factory water pump positioning.

This adapter is engineered for small-block Chevy platforms in restomod and custom build scenarios where space constraints or performance modifications require remote water pump mounting. Typical applications include custom radiator placement, front-mounted radiators in vintage chassis, engine bay reorganization for fuel system or intake manifold upgrades, and race-car builds prioritizing weight distribution or component accessibility. The 12 AN ports accommodate both braided stainless and rubber hose options, giving builders flexibility in routing and material selection.

ALLSTAR PERFORMANCE specializes in small-block Chevy cooling and engine accessories for the builder and performance market. This Block Adapter Kit SBC 12AN represents a proven solution for non-OEM water pump configurations where standard engine block ports are impractical or unavailable.
