Ok I have ruled out that I have a 50 series engine( I looked all over the place and read all 8 pages of the TDR web page post to help me find it.) Ok so the good new is that I don't have a 53
but which engine do I have? My truck was made in October 2000.

My truck was built in August 2000 and was built in Mexico. I have a large (about 1.25" high) numbers cast into the block right by the power steering pump. The numbers are "55", so I'm assuming I have the Mexico block and not the dreaded "53" Brazil block.

According to Cummins:
No 53 blocks were installed in '02 trucks. Very few were installed in '01 trucks.
Strangely enough, the Brazillian/Mexican-manufactured 56 block that was installed in many '01 and nearly all '02 trucks is the strongest ISB block made to that time. 14mm jacket castings. Superceded the 53 -- was Cummins's "fix".

I have the Mexican block in my '02-- the strongest second gen block made.
The Mexican blocks are identified by the LACK of tall 5x numbers. The 53, 54, 55, etc is a Brazilian block. The blocks that just have a bunch of small character, and no large numbers "5x" are the Mexican blocks.
Rumor has it the Mexican blocks are case with a slighltly higher Nickel content, making them stronger than even the latest Brazilian blocks which were dimensionally identical.
At least, that's what I have been told.
My truck was built in July '02 so it's one of the last off the line.....
