GM LS3 Compatible Water Neck

Description

BluePrint Engines GM LS3 Compatible Thermostat Housing is a precision-engineered for Swap applications requiring a downward angled radiator hose. Crafted from durable aluminum, it features a fixed 75-degree water neck angle for streamlined coolant flow. This housing accepts a factory style LS3 thermostat, to ensure a reliable, leak-free connection and comes complete with mounting hardware for easy installation. This water neck is an OEM replacement for the hard-to-find late model Corvette water neck but works excellent in LS swaps where an OEM LS3 style water pump is used. Also works well with Holley mid mount water pump / pulley kits.
