Mystery Crank ( Arrived )

It's a race crank............. I would say at this point, it is not balanced at all; it would be balanced to the rods and pistons of the engine build ,it (the crank), was intended for. Not a big deal, lots of rods for 2 inch journals, pick your pistons and go.
Thank you just need to know what direction to head in , my engine builder will work the rest out
