For the life of me I was trying to figure out why your engine box was so different looking than mine then it dawned on me.
When they did a engine swap 6 to V-8 they must of gotten a new box.
However when you look at this next picture the box looks like mine and you can almost bet that is a V-8 with those 2 exhaust outlets...Whats puzzling is that there literature never states a V-8
Hey but that's why we love the mystery so much.
