Mike, text me a pic at 612-701-4440 of the Cam that you have with the fuel pump Lobe. I don't think my cam has it, but if its a match.....your Golden!
the cam i got from dennis is out of a 2010 415 -502.if yours has the fuel pump lobe it is right behind the first journal and it looks different than the other 4 before the 2nd journal.i will send pic tomorrow.
They must of started adding pump lobes recently ,I pulled out the base 1622 cam and a mag 2296 core cam neither had provision for fuel pump drive ,that's going to be a tough one there
