Water Neck Riser Block

The PETERSON FLUID Water Neck Riser Block (PTR10-2250) is a precision aluminum spacer designed to elevate the water neck exit point on engine blocks. This component is particularly useful for engine builders and hot rodders who need to customize their cooling system routing and radiator positioning in modified vehicles. It provides a straightforward solution for flexible intake manifold and coolant outlet placement without compromising the integrity of the OEM water jacket.

Constructed from aluminum, this riser block is engineered to resist corrosion and thermal cycling while ensuring proper coolant flow dynamics. Its compact profile, measuring 3.9 × 1.1 × 5.15 inches and weighing only 0.45 lbs, allows for installation in tight spaces without adding significant weight to the engine assembly. The design maintains a full coolant passage diameter to prevent flow restriction, ensuring optimal performance during high-rpm operation or under extreme thermal loads.

This water neck riser block is compatible with both small-block and big-block engine platforms undergoing significant modifications. It is particularly beneficial in applications where factory configurations may limit performance, making it an essential component for those looking to enhance their engine's cooling efficiency.
