How strong is the t-56?

Getting ready to go drag my car on et streets (yes I have a 12 bolt). Just wonder if my tranny will be ok. I'm only putting a hair under 400hp and 350tq.

the t-56 in a very strong tranny stock,there's a few 10's lt-1's around here with stock t-56's.

The trans will be fine but a stock clutch will burn up with an agressive launch and slicks, time to upgrade if you haven't yet

I have a stage II Mccleod I should be fine then

I didn't break it with 800rwhp and 10" slicks, though some have. Unless the clutch is a Street Twin, that will be the weak link. Also, the OEM aluminum driveshaft has been known to object to hard launches with an M6 on sticky tires.
