The build quality of this engine stand is excellent. High quality materials. the steel was formed perfectly, nice 90 deg. bends, and all the holes lined up. The assembly hardware was also good, metric, which I would have preferred english but, you know, made in china. Two minor concerns is that the bolts that attaches the block mounting arms to the adapter plate are metric grade 8.8, equivalent to english grade 5. They are however, a large diameter so I'm not too concerned. The second concern was with the packaging, flimsy cardboard with barely enough styrofoam to really protect everything well. The box would be fine for a display at a store but really needs a heavier shipping box. Mine arrived with a good size hole in the top. Luckily nothing was missing but the plastic end caps were loose and could have fallen out. Now, on to usage This is a hefty and stout unit. I attached a Big Block Ford 460 engine and it took the weight with virtually no sag to the front of the motor. The 460 is a heavy engine with cast iron heads and intake. The casters are very smooth. It took little effort to roll the whole thing around my garage. I am impressed! Good Job Big Red!
