Looks like a V8 to me. the C36 is a straight six. The engine cover looks like C43 AMG V8 but that cover may have been used on early 55's as well, or it could have been a ML55 engine with a C43 engine cover. also look how close the the front cylinders are to the fan shrowd. Aslo look at the fan shroud which looks just like the one in the Startech V8 and not OEM Crossfire. I can also see the oil cooler on the filter housing which is unique to AMG engines. It's legit IMO. I hope he puts something up on You tube.
