I have a chevs of the 40's new water pump that I got about a month ago that I'm not going to use. I decided to go a different route and won't need this. It's a brand new pump that was never mounted. Fits the 55-62 235/216 engines. This pump help the fan sit up higher then the stock one to help cool the radiator better. The price includes the pump and the back mounting plate they sell seperatly. $110 shipped
