T56 power capacity

I just got a T56 out of a 96 Firebird. I was wondering how much power it can handle, I heard a lot of different numbers and opinions. Thanks

They are rated for 450 lb-ft. Torque is the big killer, HP doesn't matter nearly as much.

T56s have been installed in much more potent engines than 450 tq, so they take a good bit more than they're rated for, but reliability seems to start dropping off above 500-550 lb-ft.

The same gearset, case, and many other internals were used in the T56 behind the Viper V10. The only really functional difference is improved shift forks, but structurally they are the same. The gears and case are carry the same Tremec part numbers.

I have a viper t-56 in my turbo 93 cobra. The tranny handles every bit of the power. The GM t-56 handles more power then the 03-04 cobra t-56. I have buddies going 10's on stock t-56's
