How much torque can C50 clutch handle?

[jumpsoffrock]

I have been making big plans on staying with a small block and upgrading to a home-built 383 stroker--something that will bolt right in and is tried-and-true; affordable.

I looked into some pretty reasonable builds that touted 400-430 lb/ft of torque and wanted to know if the stock clutch could handle that no problem?

Thanks all.
