Greetings . . .
I got my hands on an apparent NOS crank for an early '50s powerglide car:
I plan to use it to stroke my 216 - one of many tricks planned.
During my inspection of the item all looked well except for some rather tough looking grinds on two of the counter weights:
both inlcude strange markings below the grinds:
Are these grinds part of the normal balancing work done at the factory? Or has this part since been ef'd with?
I am going to send it to a machine shop for balancing. Should I have them lighten it as well?
Any insights will be greatly appreciated.
regards,
