Dang...

Looked like it split a bore and hydraulic‘d the front of the engine off.

He keeps calling it a 318 because it was a 318 block he bored to 4 inch, probably without a sonic test. And it split.

Calling it a “318” disingenuous at best. I say that because he claims to be using “360“ pistons and they only at that can happen is with a 360 stroke.

Lots of smoke and mirrors and buckshot going on.
He is using a 360 stroker piston. Not a stock 360 piston. Which of course is 4 in. As for calling it a 318 technically the block is a 318. However is kind of a enlarged inside to approximately a 402.
