The pushrods are fine, checked the geometry and there wasn't a problem. The exhaust is such a butt plug that it can't breath. If I still have it next month it is getting a custom 3.5" exhaust, and headers after that. More tuning for the exhaust change I should get the results I am looking for. The stock exhaust was doing everything it could with the stock LS1. Did a little more tuning since my last dyno and could feel a difference, but not what I would like. Allen remember how we could never get the shifts right, I made some changes to mph shift point per gear and it shifts much better. No more drop between gears or bouncing off the rev limiter. I expect that I will make a good gain at the track with just the shift points being moved to a lower mph.
