Purple 340 cam

I wanna to buy a P4120653 solid cam but the part number doesn’t come up at summit or Jegs. It comes up on a couple of websites but they look shady. Also what’s the difference between P4120653 and P4130653AE
Thanks for your input
Go to the Oregon Cam Grinder web site and look in the mechanical cam list at grind #549. It is the same basic grind as the MP cam in question. They will grind it on whatever LSA you're looking for.
