going to an LSx would shed some nose weight, and be a whole lot easier than the longer subframe, fenders, hood, etc. my way of thinking is that getting rid of weight, is far better than adding more to "shift" it rearward. but lets ponder this....add the length, go to an LSx, now we have a longer more stable platform, at about the same or less weight. im not saying that i would do it(or even own a camaro) but im just adding to the ide-ating.
