A few years ago I was in the same situation with an engine stand. I bought a "1000 lb" cheap one and wasn't sure I liked the look of it. I decided to test it with my fully dressed 318 takeout before putting a BB on it. I bolted up the engine and slowly let the hoist down. It went down and down and down as the backplate bent. I guess it was rated 1000 lbs with overall engine length not to exceed 5 inches or something. That one got returned and I looked at WW Grainger. Turns out they have (or had) a good "middle line". I bought a 1200 lb stand at reasonable cost. Very stout and wasn't bothered a bit as my BB came together. I believe this one could handle a real 1200 lb engine.

Point is its worth checking WW Grainger.
