Probably good evidence to add to the case here. There are alot of other forces on the block besides the pressure inside from hot water. The twisting and bending loads on the side of the block near the motor mount come to mind. And in my case, the freeze plugs I have had trouble with are near the motor mount bolt holes. Jiggling, twisting, pressure inside. It probably all contributes. And maybe all that is more important than cavitation or some water flow related issue like I originally was thinking.
i'm reading this post in Z and im asking question about over pressure possibility at high RPM....anyone have take a pressure gauge and do a inrun high rpm pressure test ??
i have tested my block at 100 psi air pressure (checking for crack) and never pop a frost plug ?? so the question is if the pressure raise up to 100 psi in block at 7200rpm or more !
