Inverted it is! I turned the engine mount and it fit perfect just like you said. I used the hot knife method for the cowl and it is working pretty good. You have to go over it with sandpaper afterwards. All I have to do now is redo the throttle pushrod for when I went inverted it moved the throttle body a little. Anyone have any pics of thier muffler setup on an inverted 4 stroker?
Thanks for all of your responses!

keep it just under the vne 225 kts
