Help ID Cam Please

I have a cam I believe to be a GM cam, Its come out of a Goodwrench crate motor 2-piece rear seal, it was part of a twin setup installed in a boat with a Berkley pump.
The cam reads first "E 1" like a casting than further down is a "GM17" with a + on the opposite side also casting type numbers, next lobe space down is a "344" that is a stamped style number. I would think maybe its a marine cam of some type. Any help is appreciated.
