ive been doing some research and had bought some KB 107's to use in my 360 build, but have had 2 builders refuse to use them, saying they have a tendancy to break...crack right down the middle. has anyone had any experience with this happening? these are VERY well known engine builders, not just local guys

In a conversation with a Wyoming State Patrolman... "A 318 ??!!! But I clocked you at 142 mph!!!"
