My buddy, who I bought the LS from, has ran this cam setup for 2 PRO-AM seasons (and actually just earned his FD license) and even took it to his engine builder to have all the rings, bearings, gaskets, etc, replaced before the 2013 season started, and the builder told him there was no visible/unusual wear and everything looked great.
So I am going to stick with the MS4, and I plan on hitting a dyno shortly after its up and running to see what it makes. I will post my results
