G383 HP.....is 71 383 High performance......
11-9-70 is that the casting date on the side or the assembly date on the flat ID pad? What VIN is on it?

2468130-1---is the 383 casting number up to 1971.......

Just to be clear, all 383 blocks are physically the same. The block that the OP has was used for a HP motor.
