stock might have a set of forged pistons with arp rod bolts for sure

On forged pistons you'll be fine. On stock, I'd keep the timing a little lower or use methanol, which I highly suggest. Either way, on 10psi you should be ok. You could also use a larger CC head to drop it just a touch.

10 psi would bring you up to ~ 17:1 compression. A stretch for stock parts IMO if you want it to live. I saw 8 psi take out stock pistons with a good tune the first day it went down the track. Stock ring lands have limits...

On the other hand I ran mid 10s for 2 years at 13 psi on forged 9.5:1 pistons with ZERO problems, even won a 100 mile open road race.

I'm at 10.8cr with 10psi. I run 100% meth at 10.6-11.1 afr and 17* timing. I've had the blower on for about 8 months.

my buddy here beats his car to death and it held up fine we both had stock bottom ends making good power

Stock bottom end with a d1 &4 " pulley. I hit 10 lbs on the dyno. Haven't got to the track yet so I haven't hot max again since. It all depends on how you drive it. I baby it so I live at 4-5 lbs
routinely and then shut it down. I'm already going fast enough at that point.

At 10.5:1 NA I can only mange 18 degrees peak timing on 91 octane with my z06. Tuned many other cars around the same compression and can't get much timing in them either without 100oct.

I'm just posting this as info as octane is usually the main limiting factor assuming you have a good tune.
