Shane,
I assume you were replying to me (JGK, not GSK). I was # 4 on the list.
I couldn't remember exactly what the Chevy did, but it was about 430, I think.
I thought HeberRam did 490-495 on NOX, but I could be confused (too much smoke after his run?). Either way, it was impressive. I'd have been more impressed if it had been on straight diesel, but, hey, whatever works.
