Compression ratio

I am getting ready to start a 318 build and would like to know how much compression a stock bottom end can handle and how much is achievable. It will be running on E 85 and will be race only.

my question is if its going to be race only, and you seem intent on pushing the compression, why in the world would you risk your health and the guy in the other lane by running stock rods, etc.
Sorry, it makes zero sense to me.
And i say that as a guy who went 11.20-30’s with a stock bottom end 360 the last 4 years. But i babied the heck out of it. 6k shifts, and it was balanced professionally and put together with attention to detail. All fresh.
I just retired it, not wanting to push my luck. I got lucky.
Didn't drive over it. Due to some health issues i didnt race a ton most of those years.
