I have a fresh 340 that's been rebuilt .I've heard that 73 are externally balanced. I thought all 340s and 318s were intetnally balanced. Thanks for info.I have a used. Crank in my engine .
Talk to your machinist to find out if it was a cast or forged crank, or you could drop the pan, but then you will need another gasketMy engine has a new balancr on front .im thinking I. Have a older crank in a 73 block so shouldn't be an issue should I drop the oil pan or just talk to my machinist
