High Stall Converter Available?

i was wondering if any of the slant racers could direct me to a converter place... dacco sold me one that was rated for 2500, then when it flashes at 2k i call them and they asked my hp. then they tell me all there converters are rated @ 350hp?! so im looking for a 2800-3400 stall converter thats not 700 bucks...

anybody? its a 904 27 spline

thx
