53 block issues is rather hit and miss like the 5th gear nut problem... If you treat the truck right and let it warm up before putting it to serious work and take care of the coolant when needed... Most don't even see a problem with the 53 blocks cracking. I've even seen few of them used in racing applications and still holding up just fine... But since you don't have a 53 block no worries... Just enjoy the long life of your truck...:thumb1:

. Brazilian Blocks are cast by a company named "TUPY" and are marked such. They are identified with cast evolution numbers. #53's are TUPY's. #54 and later evolutions were improved to correct the block issues that the 53's had.

2. Mexican Blocks were made by "Teksid" these blocks to my knowledge never had a problem with cracking, as they are heavier duty by trait, but they did follow the evolutions and got thicker. These blocks do not have the 2 digit "cast number" embossed on the side, instead a series of numbers that are unidentifiable to me. The Mexican blocks were rumored to even be harder to machine do to a harder cast overall, basically better quality in my opinion.

Brazilian Tupys always seem to outnumber Mexican blocks during the ISB's production probably about 8 to 1. So basically if there is a pattern number its Brazilian, if there is a series of small numbers its Mexican.

By the way the Mexican equivalent of a 56 pattern was the Heaviest ISB block of all. This means if you have a 2002 without a #56 on it and instead it has a series of numbers that are smaller and hard to identify, you got the the big boy

Don't know if this will help you out for your search for info. Good luck!

Cummins QSOL wrote me that my engine was made at the Columbus MidRange Engine Plant, located about five miles south of Columbus, Indiana. Don't know if that's good or not. I was hoping for an amigo motor. Guess I just need to get under the old girl and find out for sure if she's a 53 or not.
