forged crankshaft

Okay Thanks guys, thank you mike. Got another question for you. Can you use a 273 forged crank in building a 340 motor? If you use the 273 rods, and use the KB Hypere pistons which are quite a bit lighter than stock 340 pistons. I understand that it will all need to be balanced, but mainly want to avoid adding metal to crank for balance, seems removing metal way cheaper thanks.
