I'm reasearching modifying a SD70MAC to have flared radiators. I came across 2 engines with the same number?? A new Evo?

and the SD70MAC

Did they scrap out the MAC and reuse the number??
Can they have two of the same road numbers?? (Different manufacturers?)
Any rules on this or just for maintenance and usage records??
