Agreed, 500-520.
I had a 454 mag (385 hp stock) and with a Vortec @ 6lbs I saw roughly 580-600.

Wouldn't a better question be - "For how long?"

I had a 22ZX we supercharged it with 50 hours 7.4 310HP. I sold the boat with 285hours and she had over 400 hours on her when the motor let go and that was because the person that bought it didn't pay attention to the oil (she developed an oil leak) in the oil cooler and he ran the engine dry. OUCH!

Ditto, mine ran strong for four years after supercharging (approx 400 hrs), then I had oil leaking through the intercooler. I did a rebuild on the motor and the only thing wrong was the valve seats got hammered and were blowing the oil back through the intercooler. The bottom end tested perfect and the only thing I had to do was a valve job and clean out the intercooler.
