Late 97 GM changed the block design by adding oil squirters to cool the bottom of the pistons but they did not reinforce the block where this was done. late 98 production saw this rectified with reinforcing. 2000 model year trucks would never have seen the bad engine blocks.affected years were 96-98 and some early production 99 MY vehicles.

Believe this to be 100% pure GM propaganda!!! That is, unless you have documentation from GM that can substantiate that??? Is it possible you have 1999 confused with the year GM simply washed their hands of and walked away from ALL responsibility for their #8 cyl. engine problem and left AM General holding the entire bag for GM’s design failures??? </div></BLOCKQUOTE>

Late engine production '99 blocks received the reinforced #8 blocks, however there were a number of left over '99 engines used in 2000. The only sure way to know is to get the production casting off the right rear of the block.

Also, the 6.2/6.5 was a Detroit Diesel, not a GM Powertrain design.
