Hi everyone
I just bought a 1970 challenger with a 440 6 pack in it.
I've been told the engine number is stamped into the drivers side front of the block but I can't find any reference of the number stamped into my block which is D120065P.

Anybody have an idea of what this number means?
Thanks heaps
Brad

 

Wire wheel the rest of that pad... Should have another number stamped on it.... If Not check the side casting number...

 

Look and see if it has the parshal VIN on the side of the pan rail...
I suspect that it's a replacement block...
