Water Neck Riser Plate

The CANTON Water Neck Riser Plate (Part No. 80-116) is a precision-engineered aluminum spacer designed to elevate and reposition the water inlet neck on small-block Chevrolet V8 engines. This 1-inch-thick riser plate accommodates engine bay constraints, custom cooling system layouts, and high-performance modifications where stock water neck positioning conflicts with intake manifolds, superchargers, or custom headers. The clear anodized finish provides corrosion resistance while maintaining visibility of the aluminum construction.

The riser plate features two 3/8-inch NPT ports for upper and lower radiator hose connections, plus a dedicated 1/2-inch NPT gauge port for coolant temperature monitoring. The included O-ring seals ensure leak-free operation across varying coolant pressures and thermal cycles. This configuration maintains OEM-level reliability while allowing engine builders to work around space-limited installations or non-traditional cooling configurations. The compact footprint (7.5 x 1.4 x 8.3 inches) and lightweight design (0.79 lbs) minimize impact on engine bay weight and packaging.

This water neck spacer is essential for engine builders, hot rod fabricators, and performance enthusiasts executing custom cooling system installations on small-block Chevy platforms. Whether adapting to fuel-injected conversions, turbocharger systems, or custom intake manifold designs, the riser plate solves clearance conflicts without sacrificing thermal management integrity. The two-port configuration supports both standard and bypass cooling circuits, making it compatible with various radiator and thermostat housing setups common in street rods, race engines, and restoration projects.
