Need some opinions before I attempt this. Picked up a 1969 383 complete engine (minus carb). I have a Larkin 4-wheel 750lb rated stand that I want to put it on. Is this doable? Am i tempting disaster? Research shows weight of a 383 to be 675lbs. There is still oil in this thing. Heads and intake also. Are these 4 7/16 bolts really gonna hold this? Am I missing something?Is there some way to additionally support it? Does it need more support. Even with a bigger (higher lb rated stand), it's still going to be only these 4 bolts holding it. It is going to sit in the corner for awhile because I have other stuff to do. Am I just worried for no reason. Advise please, and Thanks for reading.
