Quick question - TCI torque converter...

I've got the TCI Streetfighter 904 auto with the breakaway tourque convertor matched up to my 340 bored 30 over with Edelbrock 750 and Edelbrock Performer manifold. and I drive my car quite a bit when i get the chance to. Just recently put this drivetrain into my car and drove it 364 miles roundtrip from N.C. to VA and car ran awesome on the highway. Plenty of get up and go especially in the 2400 -2800 RPM range.
