[classical glass]

I,m still in the dark over what this crank is out of. It does not have a counter weight on the rear of the harmonic balancer and pulley and balancer are one piece. I do know the engine has chev pistons in (don,t know why) and runs very strong. Also can this assembly be replaced with a aluminum one? One last question if this is a 428 crank with chev pistons (wisco) stock bore, what will the cubic inch be for this engine? Sorry I don't have more info on this topic but either does the owner, who is 81 years old. But very sharp...
