340 build .30 over

This is getting build by a professional machine shop well known place. The guy who has giving me.information is not the one building the motor. He just gave me good advise on what to buy.. but anyways i am using the procomp rockers ill take my chances will give me a good reason to build a stroker one day. And yes i may need to run a octane booster. Maybe not, only time will tell. Ill shoot out dyno results in a few weeks.
