340 Steel Crank

I've decided to go the 340 route and am going to go with new aftermarket rods , pistons etc. I'm just curious if anyone currently makes a new standard Steel 3.31" stroke 340 crank or am I just going to have to use the factory steel one? I've been looking but came up empty every time. Thank you
What engine are you replacing and what 340 are you building? Do you have just a block only? A simple wanted ad could find you a 340 crank. Shipping wouldn't be too cheap but you might find one within a short driving distance.
