Do these #'s match?

Casting dates usually run on average 3 weeks prior to the build date of the car, although some lower production motors could be cast as much as 3 months in advance, and then wait for the call to me machined and assembled. This motor is for a very late build 1972 car. Is it a cast crank or forged crank? Somewhere in the 71-72 changeover they switched to cast cranks in the 340, so I assume that this motor is a cast crank motor. Check the pan rail on the passenger side above the oil pan for the VIN, I doubt it will match!! Geof
