how much can a ls2 stock bottom end take (wet kit) all stock motor.

 

there are people here who have put well over 250 through them, but you have really asked a loaded question with a lot of variables, biggest one i think is your tuning ability. tell us a little about what you are wanting to do, and maybe we can help you better.

 

stock ls2 i got a Lingenfelter timing box to take timing out i want to spray 200 @ it.

 

bump for help

 

The answer to your question is 350ish with supporting mods and proper tuning. If you spend the time and energy on researching and learning it is very possible.
