I would have guessed 730-780, depending on duration and lobe sep, if you had a vac pump, etc. I have a nice 468 in the shop right now, 13.5:1, 270 at .050, .714 lift, Victor 4500 with a 1095 King Demon, Mildly ported Canfield 310's, made 735hp and 620 on the tq. Peak Hp at 6800. I would think your 482 based on the parts in it, should make more than that.
