TCI transmissions

Does anyone have experience with TCI Streetfighter transmissions? I am thinking about replacing my a-904. I just wonder if the TIC is going to last, i have a stock 318, but am getting a 360-390hp mopar crate motor, the TCI advertises a rating of up to 450 hp for this tran. I don't want to waste my money, and would appreciate any real world experience.
Thanks,
Joe Byers
