there is not a single answer to that question. each part of the motor has a different breaking point. and more important than how much HP can it handle is how long do you want to car to last?

400rwhp may last forever.
500rwhp may last 10,000-50,000 miles
600rwhp may last 1,000-25,000miles

there are to many variables.

keep it under 500rwhp and you should be fine for a while.

since you have a stock transmission I am assuming that you also have a stock rear end. so you are in luck my man cause both of those will go out on you before your bottom end does

What is your budget? Your transmission is going to be the weakest link in your setup, the rear should hold quite a bit as it is a Corvette and not an F-body.

How much power will it hold? Anywhere between 300 and 800 RWHP (I've seen ONE guy pull that off). It's all about the tune and not spinning the hell out of the engine.

My stock bottom held 576rwhp/590rwtq (on the squeeze) NP, but eventually pushed a head gasket. There are guys that have gotten a couple years above 650rwhp (Harlan comes to mind), but that isn't the norm... The ring-lands usually go first.

It's all about the tune. Keep detonation out of your engine, it will last quite a long time. Replace the rod bolts though, as they will let you down especially at higher RPMs.
