Yep, windsor block, lost a rod, didn't hurt the piston or the block too bad, just put a window in the oil pan rail. I took masking tape and put it across the hole, then tipped the block on the stand and put the JB weld in onto the tape from the inside. Once it started to cure, I removed the tape and it left a rough texture like the cast iron, lol. Once it was painted and the pan put on it, you couldn't tell unless I showed you. It's still running today as far as I know. Made great power and was a street car.
