I have my 235 mounted to and engine stand without the bell housing, the six sets higher on the stand due to the bolt pattern then a V8 would thus it is not as stable. The bellhousing would allow the six to set lower but again it would be 6 inches longer too, my set up is ok but when you move the stand you can feel it being top and front heavy, I fell the extra froward weight would be a lot to manage and not to safe
