Did any parts break as a result? J/W, all these folks get all kinds of engine parts w/o a S/C and only get around 450whp, seems like getting a whipple would give me everything I want without having to install all kinds of other parts.
Yes, your LS3 can easily obtain 550 plus HP, by bolting on a Whipple / Kit.
Longevity of your engine will not necessarily be adversley affected, based of course on how you use and drive the car.
