No Joe:

Can't lay claim to developing this. It was Dr. Lee Swanger (Clevitekid) who did all the work and the one who did the article. I just built one (badly) based on his instructions.

If you're intent on doing a 6.2, do some more digging. He had The Diesel Depot do up a custom 6.2 that put down over 200HP naturally aspirated. Really impressive build and I believe, after over 10 years, the truck is still on the road.

Tried to find the article but no joy. Unless he pulled it, the write up must still be here somewhere.
