Bottom end info?

No problem with the block. Whenever I get any machine work done I like to mock up my engine and check all the clearances before sending the rotating assembly back to the machine shop to be internally balanced. All 340 engines were internally balanced so as long as your damper and flywheel are neutrally balanced you should be set to go. If the rods are in good shape I'd use them. They should be floaters, so check the pin to bushing clearance on the small end.
