Now for the transmission, 1st let me say that Tremec's website blows, none of the TR6060's are on there because each specific gearset (MH3, M10, MG9 ect) has been developed for a specific engine (LS9, LS3, LSA ect). The only stats they have are for the the TR6060's predecessor the T56. The 6060 is the same transmission as the T56 (gearbox) but major internal beefing has been done and I believe the tailshafts have been beefed up too. Below, you can see (In Green) the only T56 that carries a decent 1st gear ratio of 3.36 but it still has a 5th gear overdrive (lame). It is kind of heavy for a T56, once in 6060 form it would be over 149lbs. Also, the torque capacity is 350 and that is a maximum torque capacity, NOT a sustained measurement. If we are going to build a new Z28 engine, then we would have to request that Tremec build a new TR6060 and without some kind of fuel saving measure (AFM, VVT) a double overdrive would be needed... even in a production Z28.
