How much power can a stock 3.4 bottem end take?

What does it take to break pistons, rods or crank in a stock bottem end?

i do not know but if you are running stock pistons I cna tell you that is defintely the weak point of the motor.

If I was at my place i could link you to a pick of my shattered piston from my 2.8L.

what do you plan on doing to it? it all depends really on tuning.

You can have a bit more then stock but if its not tuned and runs lean you could burn a piston and such. Or if your CC is dirty you could get detonation and could break a piston that way too and on stock power levels

If tuned right, I would say the stock internals can probably go to about 250 hp. Pistons are the weak spot.
