This is an FYI thread more than anything regarding the small differences in FE water pumps. I'm in the middle of a 3G alternator swap on my '62, so a newer pump had to be installed that has the alternator mounting holes in it. Here is a good visual of a C4SE pump (old generator style) and a newer C5AE pump on bottom (alternator style).

If anyone has any other unique FE water pump photos and specs to share, post them here. There are reverse-rotation pumps used in marine applications, but I've never seen one personally. I'm sure someone has a photo of a cammer water pump for identification purposes. *cough*JayB*cough*
