I just looked up Wayne Graefen’s 300C Handbook and there is a whole section on this. The notched pump Carter M2610S was introduced after engine # 3NE572962. It also says replacement pumps with the same number didn’t have the notch. So, Chrysler did introduce it and then decided it wasn’t necessary after all!
Wayne’s book is full of detail for those that want to concourse their car, or are just curious.

Or maybe this is an aftermarket or NOSR (new old stock replacement) one-size-fits-all that Carter made available ? I doubt that Chrysler Corp built cars with a fuel pump that needed this custom treatment.

Forwarding my response to John for others who may be interested. Seems the notch wasn’t really necessary. If anyone does have an interference issue, just file a bit off rather than search for the “right” pump.

Hi John
Looks like mine attached. Years ago, I think there was something about the number stamped on the body to identify the 300C pump but I don’t remember what that was. As you can see, the notch doesn’t make that much difference as installed on my car but it is there to clear the front of the block.

I've heard stories about a notch in 300C pump bodies. Does this look correct?
Thanks for your input, John Lazenby--
