3782608 water pump dated April of 64.
 

Small block Chevy. Dirty. Grimy. Was not leaking and did not make noise when I pulled it off last month. But, it should probably be considered a core. Good news is it came off an engine with oil leaks everywhere, so it is covered in black grime but should be pristine underneath with no rust or pits.

Just pay shipping. PM me if you want it.
