[QUOTE="powerstroked08, post: 1410020, member: 8135"] The pistons cracking is pretty much just a random sh!t luck thing. Honestly, there are trucks that are north of 1k hp on a stock bottom end holding up fine. While there are sub 4-500 hp trucks popping pistons just gently cruising up the road. I really think there is a flaw in some of the castings, not to mention the major lip that is on the stock pistons that is contributing to the failures. But back on topic. The 6.4 in MY opinion is a great motor, while it has flaws(like any other engine) it can make and handle a ton of power. But like stated before you have to maintain the damn thing. Mainly the fuel. This is a common rail. It NEEDS CLEAN FUEL. I can't stress this enough! So with that said I say 6.4, but that's just me. [/QUOTE]
