forged crankshaft

Confusedcuda said
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.

Should be able to. The 273/318 rods are the same dimension just not as beefy. The 273 crank probably has a smaller converter register if you are running a automatic. Check with your machine shop to be sure. Taking weight away is pretty easy. Adding weight is quite expensive.
