Who has ordered a passon A-855 ?

I can tell you for sure that the TKO 600 will not hold 600hp/600tq my buddy mustang with a World Product 427 small block 552hp/575tq destroyed the 600 with slicks. Tremic says it will hold up but it didn`t he had to have it rebuilt and switched to a Mcleod RST clutch and soft launch its holding up now hes looking for a Viper 6 speed.
