what pistons to run with set up??a bit of help

It can be done, I run 9.7 measured compression on 87 octane in my truck. That's with shallow open chambers (no quench), a short duration cam, and aggressive advance curve. Careful chamber prep, cold plugs, proper jetting and oil control all help. At 2800 MSL, I have elevation on my side as well.

I have built a few for locals with comp above 9.5 to1 ,no special chamber prep,plugs that live on the street,without quench and no issues for daily driving or T&T,bracket racing. I wouldn't do the same in a 4000lb,.3.23 geared,stock converter application. Too many variables to make a blanket statement. It's all in the COMBO. Yes,I'm very close to sea level.
