I would increase spring rate a little bit. the 450s seem a little stressed, but work well for me and I've got an LS with some composites and aluminum on the front end. If I added anymore weight, I would increase spring rate a little, especially if you plan on running 200 or less treadwear tires. With the additional 75ish (or more) pounds from the supercharger, I would start to worry about getting a little bit of coil bind, especially if you're using half height body mounts.
How much to increase spring rate is the question though. I would research what Stielow is using in Red Devil, for a starting point.

*edit* we've also just been assuming that you bought double adjustable shocks, but I'm not quite sure how relevant that is to your original question.
