can my driveshaft handle the 401? & How to tell what tranny I have.

["deezildennis" <dsinks@xxxx>]

specs on the engine. Stock rebuild with summit tamer grind cam, 
torker intake and undecided carb, either e 650 carter or a 750 holley 
I havent yet decided.

Anyway, will the stock driveshaft handle it? Or do I need to start 
looking to get one made?

Also I pulled the tranny this weekend and i am trying to find out if 
its a 904 or a 998.

Its a stock v8 tranny.
