sirmopar, you may want to broaden you search to early 318 cranks as well they were steel and have the same stroke....
some where I heard that the newer forged rods and pistons are lighter than the old and would be ok on a re balance anyway without the cost of adding mallory metal ?????Counterweight is different
Just for info. I have a 318 steel crank at a machine shop. He is gonna drill the holes in it to match the 340 crank. Kim

Get with @krazykuda Karl. He's in the Chicago area, not too far from you. Maybe he has one.
GTX JOHN - what part of the world are you in? I'm in Northern Virginia and might interested in a road trip and exchanging those funds for a 340 crank...I have two real 340 Cranks Std $150. but shipping would be a fortune!

I’m in cheboygan , zip 49721. Not in a big hurry. Hopefully in the next 3-4 weeks. I have a cast crank I can use if I have to, Was hoping to rebuild with forged so I don’t have to weight flywheel.About where are you in Michigan and are you in a hurry?
thought older 340/318 where INTERNALY balanced thus neutral balanced fly wheel ???eI’m in cheboygan , zip 49721. Not in a big hurry. Hopefully in the next 3-4 weeks. I have a cast crank I can use if I have to, Was hoping to rebuild with forged so I don’t have to weight flywheel.
