Ya'll can bust all you want on Harbour Frieght stands but all I can tell you is I have a few, 2 of which are holding BB and have been for a year or so in my shop with no issues. And if memory serves I caught the on a supper sale and gottem for less than a hundred each. I had an all aluminum Hemi on one for awhile and it didn't really seem to stress it but I cant say that I have had an iron Hemi on one. If I was looking for another I would buy these in a heart beat. If I had concerns about stability at that point I might build a jack stand to meet the balancer as a precaution. The plate mentioned above seems like a great idea as well.
