How did you pick your torque converter?
i called dynamic. talked to sean. gave him my intended use and my combo to the best of my knowlege. the thing was dead on. worked great. mine came in at about $600.
call dynamic,ptc and ultimate. see what they can do for you. i think in th elong run you'll be a lot happier with one built to your combo..
