I have my 350 block mounted to the engine stand with the lower arms parallel to the ground.
I don't know if I can drop it farther.
The bare block itself is top heavy...a bear to roll over right side up.
Though the crank c/l is below the c/l of the stand's head mount,
I doubt that it will offset the weight of the heads and pistons,etc.
How balanced can I expect to get it, and should I be doing something different?
