I currently have LS7's in my bracket 6 liter that we drove with a turbo on the street for 4 years. I've run them up to 72-7300 and haven't run into any issues as of yet. That being said I have two other engines we are doing that have the Johnson hydraulics like Darren along with one that is a low lash solid roller setup.
