socket size for a small block mopar crank shaft bolt?

Dam, I have never seen that b4. Kim
Neither have I, and I have been fooling with small block mopars for over 35 years.
The engine came out of a 73 Charger, the guy said it ran and the trans would still pull the car around, but rust had gotten to the charger, he still had the car, in my opinion it was fixable he just parted it out, because he had several nice of the same era Chargers.
The engine, did end up being a nice builder, just needed cylinders honed.
