Product Details

Edelbrock has been making performance parts for a long time. This waterneck is a polished cast piece that's designed to give your engine bay a clean, finished look. It's a straight neck design, which works with any 1-1/2 inch diameter outlet hose. The O-ring seal is a nice touch, meaning you can take it off without needing a new gasket every time, which makes maintenance a bit easier.

This waterneck fits a lot of popular Chevrolet engines, including the Small-Block Gen I (like the 350) and the Big-Block Mark IV (like the 454). It's a simple bolt-on part that helps complete the cooling system setup.
