1st 340 build

Not to highjack this thread, but I want to pull my running when parked cast crank 340 down and at least freshen the bearings before I put it in the Duster. I picked up an aftermarket steel flywheel for it and have the diagram for drilling it from the DC chassis book. How different, if any, is the counterweight balance of a steel 318 crank from a steel 340 crank, and would be worth the additional time and trouble to use the one I have from my '67 Coronet?

the balance between the 1967 318 forged crank and the forged 340 crank wil be the same,,but i believe the 67 318 forged crank is the same as the 1965/66 273 hi po forged crank,,if so the torque converter register hole may be smaller, then the later small blocks,,but im not sure when they changed the size of the converter hole,,,

ide be intrested in finding a complete 1967 318 forged crank engine, as a replacement if i end up needing a momtor for my street rod,,
