Block numbers?

[Govt issue]

I have a jasper reman engine in a c 3500hd that i am working on at my job. It has a block number of 929 in the valley. What does this mean? good or bad block.

last of the non oil spray i believe, mid 94-up to 96 when the first 506 came out.

I have the same block from the Diesel Depot and according to them it was the replacement for the 599 block, the last 6.2/6.5 block made as you say. In all likleyhood a Mr Goodwrench replacement engine.
