There's a fella on YT that took a 318 bottom end to it's limits and the crank broke. For you uncle Tony fans who may remember, Tony with his lack of anything in the way of automotive knowledge and intellect, made a video on the Gary fellas. video stating it was a timing chain failure, but he was once again wrong and making up stories. The point is, evidence is out there about what happens when you try and make a 318 into a race engine...you can only take it so far.
