I thought that as well at first.Thought maybe the guy had left straight water in it for awhile before he started it and it froze and busted.I saw a 289 in a Mustang freeze and bust on both decks between most of the water jackets.It contaminated the oil ,but it also ran like crap with the water in the combustion process .This guy was saying it ran well for 5 minutes ,so i kinda put that theory on the bottom of the pile .At this point i am really getting mixed up with this one :banghead: ???
