Ok I just have to ask this. You are talking about a gas engine, a big gas engine and you don't even know what direction the prop swings???? Now unless it was purposely set up to be different all engines turn over in the same direction and props will be be pitched for a counter rotating engine when viewed from the front of the plane, so taking all this into account why and the heck are you messing with an engine that is clearly out of your experience range?
