How much horsepower can stock transmission clutches take before slipping?

 

i was told by a tranny mechanic that happens to work on chevy's, that the stock tranny is supposed to hold almost 500 horses... but i doubt it, usually depends on what the car has modded

 

Very difficult to answer. Depends on the tune, driving habits, weight and luck. I would say anything over 400 gets questionable and over 500 is living on borrowed time.
