I have zero faith that I will not eventually find other issues in other cylinders. This engine has never even been pressurized. We were simply turning it over by hand getting ready to install the distributor and noticed coolant coming out of the cylinder. It did not even have a cap on the radiator. If this is what one cylinder looks like, I have no reason to think the others are solid.
Already have a 67 block that is stock bore ready for the machine shop to work on.
