I don't believe that any G506 has an exhaust mounted oil filter, and the carb/governor are 90deg off. The intake looks right. Also, that spacer between the carb and governor should not be there. I have both a civvy and numbers correct military intake the civvy one has the stud mount perpendicular to the engine. The military one parallel. I'll post pics later on.
It looks to be an actual G506 motor (you get a peek at the oil pan as he walks up to it) just got some civvy parts that don't belong.
Those doors look great! 7 new NDTs (you'll regret that).... started right up. I can't believe its December when this was shot. Must be AZ/NM or Australia
'Nice truck!'
