Here's a post from last week on this same topic:

As Lloyd said, it is possible but maybe others will chime in with their build dates/motor numbers to compare from the same plant. Still no way to be certain on a '70 without finding the build sheet as the PHS for '70's does not give the motor unit number as the '68 and earlier PHS would. OPH can probably look at a motor unit number and the build date of the car and tell if it's in the ballpark for that time of the year so hopefully he'll chime in. Rick
