Can you tell me the build date?
How you decypher it?
how did you figure out it was #375
what Does #375 mean?
Does it mean it's the 375th engine made a mercury marine?
What are your plans for the motor?
I'm interrested in seeing the differences between a pilot and production motor. Do you plan on archeological disassembly project.

Eric, I told everyone there they could own this 89 LT5 didn't I? I waited until the last day of the listing before I pulled the trigger! It has been up there for over 4 months.
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
