cast crank to forged in 440

Yes, you can remove the weights. I'm surprised to hear your crankshaft is forged steel being a 73. 440'
My 440 is reportedly out of a RV (crammed it in a 73 Duster). The damper that came on the engine is the same as the 2nd photo down (#3614371) on this website Harmonic Dampers 440 Source.com and the counter weights on the crankshaft are rounded as can be seen in this photo. This photo was taken when I first opened up it up after who knows of how many years.
