I've only seen Tige dealers run the raptor 360. Also seems like most dealers advertise the raptor 400 as 400hp. In reality it's only 350hp & 404torque. I do know the 440 is basically a flash upgrade & Orange engine cover. Not sure on the 360.
I was reading somewhere on one of these sites. Maybe MB forum but someone found a company that would do it. No dealer will do it though.
