Engine Code/Partial VIN Help. Pics Inside.
Hello everyone. After a long weekend finally got the engine out of my 87 IROC. I need help or explanations to what these codes mean. Are these engine codes, build dates, partial VIN, etc. Both codes are on the back of the block behind the heads.

Both pictures show the engine is a 5.0 liter.
I found this chart with block part numbers, look at lines 8,9,10.
