Use a table ban saw to hack off the 340 piston crown .

I did read some of the very beginning of this screwed up idea he has. I can't believe that someone would screw up a set of pistons like he is going to do. Does he even know if he'll have enough thickness left over to keep the piston from coming apart? If he doesn't believe in machine shop work I'm willing to bet that his engine will have some serious vibration issues.
Not screwing anything good, believe me .
