I took out a 410 and am replacing it with a 445 with aluminum heads and a hydraulic roller cam.

I was going to re-use the OEM water pump and starter, but there is a used Edelbrock 8805 water pump and Powermaster 9506 starter available fairly locally.

I have no idea how old the OEM pump or starter are, they both worked, but I think the Edelbrock will flow more, and the Powermaster is smaller and will be less of a struggle to install (and remove later one) than the OEM starter.

Before I make an offer I thought I'd check to see if any of you have had problems with these after they have been in service for a while. Seems you cannot buy the parts to rebuild an Edelbrock water pump.

 

Starter I would take a chance on. When it comes to cooling and oiling, new parts on a new engine. JMHO.

 

After spending the money on a 445, I wouldn't skimp on a water pump.
