It needs a rebuild and was wondering if anyone knew where to find the correct #'s off the block to see which motor i'm dealing with b/f i dissasemble it. it may or may not be the original. it's a duelly so i assume it's a one ton, correct me if i'm wrong.

The 2 or 3 letter suffix at the end of the stamping will identify the original application. Virtually all the truck engines with 4-bolt main bearing caps have a "T" as the first letter of the suffix.

You will find the block is stamped with a casting number and date behind the driver side cylinder head. Combine that info with the suffix code (2 letters in front of the passenger side cylinder head).
