Just noticed the markings on my block and wondered if anyone knows how to lookup the engine info? PO said it was from a mid 80's van maybe? 2 #'s:

front of passanger head there is a platform, usually behind the alt if you have a long pump setup. Mix of numbers and letters. last three letters are the most help.
Then rear driverside head right next to the bell housing there is a large number there. 6 to 8 digits all numbers
Close to your UKR did not find yours exactly
1981 UKA 350 con. cab, m/t, A.I.R. P LF5 150 2 C-30 & 3500,159.5WB
UKB is the same as above UKA
Not sure what the CG number is the casting of?

Thanks booty.
There's a set of books by Bentley Publishing, written by Alan Colvin, that list the ID codes and casting numbers.
Unfortunately, the one I have is only for the cars from 70-75. Thats the latest they went with the series.
Basically, (based on the info from my book), the first set you listed is the engine ID code.
I know Chevy revamped there casting number system in the early-mid 80's, so the format might be different...
But anyway, using the form from the 75 model year, the first set breaks down as:
V = This motor was assembled at the Flint Motor Plant
03 = Assembly month (March)
04 = Assembly Day (4th)
U = Motor Division (My book says this should always be a "C" for cars, "T" for trucks...Maybe "U" was for vans and heavy equipment? Maybe for "U"tility?...
)
KR = Suffix (This is the most important part of the code. This would give you Model of vehicle, displacement, horsepower rating, and transmission options)
The 2nd set of numbers is the VIN info...This is basically divisional identification number, model year, assembly plant designation, and vehicle serial (sequence) number.
The set you listed, doesnt match the format in my book, though...
The good news is, there are a bunch of casting numbers and symbols on different parts of theblock, that can tell you for sure where, the year, day, and shift that the block itself was cast at. Cast parts were usually assembled within 3 mos or so, IIRC....Unless the block was inventoried as replacement parts, but then it wouldnt have the Engine Code and VIN stampings...That pad would more than likely be blank...
If you make a list of all other numbers and symbols on the block, I may be able to give you some more specific info on your block....
HTH
