I haven't heard of it either. That is just a representitive pic. If you scroll to the bottom he is selling kits for a bunch of motors. The price says stay away, a good set of pistons alone cost that much (actually a bit more). The owner of my Raider before me put junk like that in mine and #3 piston broke less than 30mi later. I rebuilt w/ Weisco and Clevite and it has about 40mi on that build, you can check w/ Mississippi Blue to see how it's running.
