My car came with a 460 and 3550 big input tranny originally. I'm installing a 700+ hp approx 650tq 545bb and have already bought tko 600 w/.82 od. After talking to Cobra Valley guy I was told to stay with the 3550 with upgraded shifter because tko 600 can be difficult to shift and 1st gear has a tendency break. I have a 2450.00 tranny and not sure whether to use it.
