I JB welded a motor block back together on a small block Ford once. It was broken out where the motor mount bolts on. I cleaned it up good and glued it up. I drove it for a lot of years and it was still holding, never leaked a drop of coolant
B-JS how are you putting air in the fire hose ???
OK guys, we are in the company of a serious bowyer. It's not often you see a gallon kit of EA-40 in the workshop!
