I don't live in Texas, but in Missouri, I would plug all the engine info into my engine program, and input the octane fuel, and it would tell me exactly what would live. From my experience some where with 110 centerline and 230 or so duration should work just fine, built several like that for street cars. Just finished a 406 small block chevy, it has right at 10 to 1 pistons, it has a 110 centerline, advanced 4 degrees, 220 duration, with .500 lift approximately, it has around 140 psi cold cranking compression, and runs fine on pump gas. Dyno said it makes 357 HP @ 5,500 rpm and 457 ft. lbs of torque @ 4,000 rpm. from my memory. Went into an older corvette. Built several stroker 360 mopars with basically the same combo they all worked great as well.
