Torque converter help

Need help on getting the right TC for my slant six 225. I've been off and on with summit racing about part # HUP-27-25 (this is a custom TC) I've gave them all my info and still they haven't called me or emailed me. The cam I got is a P4286681 (no cam card). Mopar purple camshaft 490/276. The engine is 30 over with a offy intake,headers and 500 cfm. I need something for street/weekend driver, it's a dog off the line. Thanks Fabo
