wtb staged or puck clutch, keyed crank balncer hub, and crank pully for procharger

[96 SS 383]

im needing a more heavy duty clutch. not too sure on whats the better options on clutches but needs to rate around 500hp (not quite making that but would rather have more than i need than less). i currently have a fairely new (6,000 miles) basic centerforce and getting slip and wont hold the power. open to suggestions on clutches. Would be interested in clutch/flywheel combo as im still running stock flywheel. Im also looking to buy a procharger crank pully. its a bigger pully only on 5psi on p600b i will get exact size later. and last looking to get a keyed crank balencer hub. If someone has some of these parts theyd sell it be appreciated. Thanks.
