What is the Original Application for this Radiator?

[71GSSDemon]

So, just got back from MITP, upper 90's and 5hr drive each way. My Demon was running 190-200⁰ the whole trip and climbed to 210+ when having to stop. The current radiator is number 3443 951. Anyone jnow what this came out of (other than my friends shed as that is all I know)? I will get a new aluminum one for the same application. Thanks in advance.

Ok I don't see the 951 anywhere, but all 3443 seem to be 1971 B & E body big block.
