MattW OP master M Joined: Jun 2005 Posts: 2,776 Ontario Canada	So i picked up a complete 5.7 out of a 2016 challenger. Hydro locked and snapped a rod. Didn't touch the head or cylinder wall. This thing is new inside i would guess less than 10k on engine. Questions I am replacing the rod with and earlier 5.7 rod. Are they the same weight? I'm pressure testing the head and block. Don't know why it hydro locked. Possible bad gasket from factory? What else should i look for? Thx Matt
