Looking for original 340

Looking for my original 340 engine. Was last seen in the late seventies in the Roanoke Virginia area. Vin # 9B325911

Should that 9 be a 0 ? On the 10000 day calender 3259 is June 30 1970. I have block #0B326754 and it has cast on the side 1-5-1970 ,3267 is July the 8th 1970 which I'm assuming is the assembly date ,maybe I'm wrong
