I'm not sure where the information originally came from, but the latest news at www.thedieselpage.com is that 82 blocks had more nickel content than later blocks, and that some military 6.2L blocks also had higher nickel content. We're still trying to confirm that. It does appear that broken cranks and cracked main web bearings are found more often on 83 and later blocks than on the 82's.

Another thing the 82's are supposed to have going for them is a different camshaft gear, which changes the timing a bit, as well as the heads have larger valves than some of the later 80's engines. However, the stock fuel system and injectors don't allow for as much power, as well as more restricted pre-combustion chambers.

Seems like one of the latest trends now is to find either the 599 92-93 blocks, or find a good 82 block, for rebuilding a heavy duty 6.2L.
