..............If I mounted the engine sideway's as the plans call for, all would be fine. I would be in better shape with a slant sullivan or other. Problem there is drilling the firewall thru the nose gear and engine mounts. Not workable.....yet..............
You mean drilling holes in the engine mount for the nose gear? They might be pre-drilled, based on some of the engine mount pictures you've posted.
