I use one as well, they are a great tool but do add considerable height to the hook point. My shop has a high ceiling with chain falls on an overhead track so that extra 8" or so doesn't matter to me here. Though with a cherry picker and a heavy deep oil pan big block it is hard to get enough height to clear the radiator support and not tip the picker over from having the lift arm too long. Did one like that at a friends garage that has a lower than normal ceiling and couldn't use the leveler because the picker arm hit the ceiling, took the front wheels off and let the front down AFAP, no dice, oil pan wouldn't clear the rad support. Had to go back to the three hole carb plate attachment. So we put the wheels back on it and pushed it outside so we could change the setup. Of course it was raining cats and dogs so we had a wet car to work on when it came back in. I could have moved the chains from the intake bolts to the holes in the ends of the heads for a lower attachment point but the engine was going in fully assembled with alternator PS pump, and A/C compressor on it. Fun times...What's next? :)
