Whats the bore on a stock ls1? What is the next bore you go to if you want to rebuild after 190k miles. My engine is leaking and oily but original. I have a 2000 model caprice (australian). Is there any loss in power after rebore?

You really cant over bore an LS1.

Stock is 3.898

You can go to 3.903 or 3.905

No loss in power if you can still get a good ring sealing surface.
