Newbomb Turk you seem to be down on anything posted about the Magnum set up. From personal experience, we have run a 5.9 Magnum in Stock Eliminator and Crate Motor classes since they were allowed in 2000. We have had NO valve train or engine failures and we have beat the snot out of the engines. We've won many Divisional races and two Nation events with a 2000 Dodge Dakota weighing in at 3430 lbs. If you are so unhappy with Mopar, go somewhere else!
