This isn't a freaking 318 vs. the world thread.

Just because it's no about a 318 doesn't mean it's anti-318.

I was being facetious about 318 comment. As seen in that video the 4 inch crank trick flow head 318 block engine made 530 hp which is pretty impressive and some thing anyone with funds could build.
