Are we talking vehicle warranty or engine warranty? If you're talking vehicle warranty, I'm with everyone else saying no, you do that stuff in your new Camaro, you can kiss the warranty good-bye. If you're just talking about swapping a LS3 for a crate LS3, then sure, you'll have the engine warranty, but that'll be limited to whatever parts GM approves for that engine. I'm with a mild cam and LTs and call it a day. If you're just trying to be different, yeah, you're doing it, but at no real benefit other that cosmetically. Hey, it's your car, and if that's what you think is best for you, then atta' boy
