Good job! I love this build mostly because it was a shocking budget/easy way of makeing the bigger cube motors make crazy power without crazy mods, but now you're pushing it to its capabilities.
So you're using 6.0L truck manifolds flipped? Are all 6.0L manifolds the same, I would imagine the truck's are different from the suv's. They seem to fit pretty well what were you using for manifolds previously some custom ones from the kit?
