reliable 600 hp 6.0L? Those words almost don't go together! LOL Good luck on getting that! You are gonna either have to find someone to do your studs over a weekend or have your truck down for a bit and put it in the shop. You are gonna have to have some mighty big mods to get 600 hp out of a 6.0L. I would not waste that kind of $$$$. I would just get me a 6.4. It would be much easier to get that kind of HP out of a 6.4 than to try and get it out of a 6.0L IMHO. But I would love to see it!
