What help do you need?
you have casting numbers which identify the blocks.A 599 block is the one everyone wants crack free to start with

The 599 block is a non squirt block (No piston coolers) and has the large outer main bearing bolts
I have seen these in the 1994 Burbs and pickups.

A crack free 599 block is a good find.....

[Sdaigle1965]

Casting number is.D073

[Sdaigle1965]

The 929 is.A265

[Robyn]

The D073 is the date code April 7th 1993 casting date

"D" January is an A February is a "B" and so on
"07" Seventh day
"3" 1993


The Block being referenced as "929" .....This is the last 3 digits of a 6.5 diesel block....Circa 1993
