Engine/Transmission (1998.5 - 2002) 2002 Truck

Do the 2002 models have the "53" block? I would like to buy a 24V 2002 model. I want this year because of the 4 wheel discs and no central axle disconnect. Does anyone have a '02 4x4 for sale? (auto or 6-speed).

My 02 has a "56" block. They are supposed to be OK. I think some of the early 02's still have the axle disconnect. Jeff

No 53 blocks in the '02's *I* have ever heard of...

55 on my 01



the best way is to get on your back with a light and make sure what it is!

I do believe that by 2001, all the 53 blocks were phased out, and replaced by the 55 block. The only blocks I have heard of on 2001 and newer are the 55 and 56, but there could still be some of the elusive 53s floating around.

... To add still MORE confusion, MY block has no large "5x" number at all - just a smaller string of numbers/characters (I forget which), that supposedly signify a Mexican block.

"1. 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 mexicans 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.



I had a 2000 that had a Mexican block. I looked and looked for a pattern number and all I could find were the smaller series of numbers. When I bought my 2002 and checked the #56 inch high is very easy to see. If you don't see a #53,54,55,56 and only find a series of smaller around 1/2 numbers that are hard to makeout then you have a Mexican block. "

I have an early '02, and I still have the CAD.
