Tom,
If you look at some of the performance tranny places they seem to offer either OEM or "Heavy Duty" flexplates (any link here is added by some outside program), and their HD units are in the $90 range. In the HP range you're running I'd be comfortable choosing a mid-range HD unit from someone like Summit, Jegs, or if you prefer, from a tranny place like Monster Transmissions who package them together every day. Just my $0.02 from a layman's view.
