GenIII Hemi & Supra 5-speed?

I posted this in the New Hemi Swap section, but thought it might be a good idea to post it here for a perspective from more driveline specific tech input.

I know guys have been putting the Supra trans behind small blocks, but not sure what model. Is the Supra trans strong enough to handle ~500HP? Will it handle full throttle clutch drops? What bellhousing does it require if it's feasible?

Thanks for the help!
