Here's some engine pics. My uncle rebuilt this one. It's a standard 383 so it should have been painted blue, but I'm not complaining. Period correct anyway. Car was built in October 1969.
From what I understand, the 330HP "L" motor was blue and the 335HP "N" motor was orange. The serial number is N but the motor is stamped 383 by the distributor.I'm no expert, so someone who is reading this who knows exactly please correct me if I'm wrong.
Didn't the 70 N code come orange and the L code come as blue?
Yours being a D21 4 speed I would suspect it is an N code 383.
The numbers 9C278361 are stamped on the lower right side of the block, just above the oil pan. I have no idea where the motor came from or what happened to the original.Do you know what the motor came out of? C body probably. Does it have a vin stamp on the passengers side oil rail? That might shed a little light as to what it came out of. Not that it really matters or anything, just curious.
