[QUOTE="Guy, post: 1240594, member: 22717"] Word on the street is that the crankshaft can’t handle more than 650-700bhp. Thermal breakdown of lubrication due to excessive heat, excessive heat leading to metal expansion beyond safe limits, inadequate lubrication for all of the above. Too much rotational force... From what I’ve heard... and I’m not an expert like my man from Livernois.... is that the cure is a built crankshaft with stronger bearings and improved oiling. In other words... to get these things up over 550 wheel horsepower you’re talking about an engine tear down and rebuild as a race engine essentially... to maintain reliability. — Big Bucks I don’t think our man is going to find a flaw in the engine or the block that is unique just to this engine. All speculation until Livernois weighs in! If you want 600 ponies at the wheels... I hear another manufacturer is working on a certain 6.2L supercharged version of an off-road truck. Blasphemy I know! Lol [/QUOTE]
