What's the compression ratio and exact cam specs?
You'll probably be OK for a low-boost setup if your CR is around 9.0-9.5:1, although I would highly recommend a teardown to coat the pistons and open up the ring gaps a bit, which means while you're there you could benefit from a SC-specific grind cam.
What headgaskets are you currently running?
Carb mods and a boost retard of some sort (MSD 6BTM or equivalent would be easy) would also be a must.
550-600hp is not asking much if your CR is in the right ballpark.
Still, don't expect to do this for less than $4K or so, it adds up quick (SC & bracketry, good carb hat, carb mods, fuel system upgrades, etc, and I highly recommend spending the extra $200 or so to retrofit a GM spring tensioner on the SC bracket. Procharger's stock tensioner, in a word, sucks.
