Has anyone here had one of these blocks sonic tested? If so could you post the results as well as the casting number of the block tested. Also if anyone has had one bored, did your machinest mention anything about the hardness of the block in regards to how well it roughed and finished.
I have a friend who once beated a 302 into pieces to see what the wall thickness was (a fight between his wife and daughters had something to do with it ) I think it ranged from .140 to .240. I don't remember if it was standard bore or not.
