The easy way to tell if the motor is in the car is to look at the harmonic balancer. If it is thin, it is a 383, Steel crank - if it is thick, cast crank - 400. Bill is right, they started casting blocks in Apr of 71 for year 72 production. Earl A block cast in July, 1971 would most definitely be used in a 1972 model. The blocks are cast three or four months before being installed in a car. They are usually stockpiled before assembly begins. You can tell the model year of the engine by the engine number (ledt side, rear of block) which gives the day the engine was assembled, or the partial VIN on the block (right side, just above the oil pan to the rear of the engine mount.) which is for the car the engine was originally installed..

He also seemed to know enough about Mopar , that he would know about the dates on blocks. As to the cold weather thing, my book, by Chuck Senatore is unclear, he makes it sound like all blocks between april and october 1971 were cold weather blocks in addition to being thick wall blocks which seems hard to believe . He mentioned that the cold weather blocks had larger than normal numbers cast on them. I dont know, I'll probably never know. I understand there was a 440 cold weather block too, but he ( Senatore) said in all his time he had only seen one. As a final note he also refers to them as industrial blocks as well as cold weather blocks. I'm sure it doesnt matter cold weather or not, I'm sure the 71 block is plenty stout, as is the 72, which I have also found , a complete running one.
