Use a table ban saw to hack off the 340 piston crown .
Glad your not too serious, I am enjoying it also...so what if the cut don't turn out right. Check out the JE piston rejects got for this challenge...they sent me morethan I ordered(only3) . Got 7 instead...less than $10 a piston...if you see one you like, needing an extra, pm me an address and I will mail it to you for free, won't hack it.
