600 hp 318?

He also fails to mention, (or probably doesn't know) that the 340 main caps are thicker. And he keeps talking about his bore being only .090 smaller than a 360, (its .130 smaller than a STD bore 340) and how minor that is, but he doesn't mention you have to multiply that by 8 unless you have a one cylinder 318 or 340. And probably the MOST important fact missing, is that thick cylinder walls make MORE power than max bored thin cylinders. Remove all his rotating assembly, (and topend) put it in a 360 block, and it will probably make more power due to thicker walls and a stiffer bottom end.
could be filled with hard block!
