? on engine block date/ car bulid date

[Tommy_Mathison]

Hi guys. I just recently bought a 69 Z/28 (X33 Lemans blue/ standard blue interior, blue light stereo, rear defrost, m21, cowl hood) The car has no motor in it. trans partial vin stamp matches the car vin, orig. BE rear. <font color="red"> My question is this; What is the range of engine block build dates this car would have came with from the factory?</font color> I just want the car to be as original as possible.
