I got this crank out of a wreck 540 talldeck block and Iwould like to get some info on it. This is the information etched into it. Can anyone tell me what it means and if this crank is undercut?!!!

Looks like the main and rod journals are STANDARD. You will need to verify with a calliper. Based on M=main and T=throw

I think this number is still good:
