Anyone done this?

[90'5.0 Conv]

I've heard that the c4 could handle up to 1000 hp but like I said just heard. As far as torque, I have no idea but if it can handle 1000 hp, I would imagine it could handle the torque of a 400-450 HP engine but like I said I'm not positive. Thats why I'm here, hoping someone could tell me. The 428 is a definite. As far as the c4, if it can't handle it, then i can get a c6 for cheap but once again, I'm unsure about these trannys as far as what they can and can't handle.
