Okay, that's what I thought. I've not seen too many 8.2's but I was pretty sure that that was a clean sheet of paper mistake. To the best of my knowledge the 6.2 / 6.5 was also designed as a diesel, although it borrows heavily from gas engine design. GM claimed it was DD engineered, but it reeks of Chevrolet. I've been unlucky enough to own four of these (three in one truck alone) As usual, GM sorted out most of the problems by the time they went out of production. Many people confuse it with the 5.7 liter Olds which was a gas conversion, and the Toro-Flow lesson re-learned.
