Need help identifying 6.5 blocks

12552929 and 10149599.thanks

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.....

Casting number is.D073

The 929 is.A265

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
