I have been told (can't promise it's true) that the 776, 777, & 778 (last 3 casting numbers) blocks are thicker than others due to them being a Canadian block???? Like I said, don't take this as a proven fact, just what I was told when we built ours. We have also ran the 909 block with no problems, but it wasn't on Knoxville's list so we changed.
