I just got through pulling my 235 with the engine hoist 2 days ago. I started to buy a Harbour Freight stand but found one on Amazon that appeared to be sturdier. It didn't attach on-center, so it is off balance. No other way unless you attach a plate like Hotrod Lincoln suggested. It will take some time to fashion one, but that would be the safest. Now the problem became trying to fit the stand inside the legs of the engine hoist. That took some jostling around and setting the hoist on 1000 lb. setting so it would extend out enough to be able to drop the engine and align it with the stand. Finally got it nestled but added a 2x4 cut around 20" with a flat board on top of it to fit under the pan to hold up the front of the engine.
Cleaning time but just not sure about turning the engine on the stand. Chances are I will end up putting the engine hoist back into action with a chain around something up front so I can remove headers, valve cover, side pan and oil pan for cleaning..... SAFELY.
