Before 1990 production motors started, MM would stamp the assembly date and an overall sequence number on the oil pan boss. When 1990 began they did a date based sequence. So if an LT5 was made on the 1st of June it would have a sequnce specific to the 1st of June. on the 2nd of June they would start at #01 again. So 375 means it was the 375th LT5 built at MM before the 1990 model year LT5s.
THe build "assembly" date as seen in the photo is 12/20/1988
I will go over this LT5 and see what I can see. I need to make sure it's a runner. There are lots of little changes between the two. I will try to post them here as I can show them... Stay tuned! Eric

So what are the motor #'s for #4 and #74? Any idea how meny Preproductions LT5 there were?
