Proper quench is very important, 10.5:1works well with 91 octane, stock rocker gear, single springs with damper, Torker intake port matched (high velocity flow) 2" long primary headers, stepped if possible, 800 cm Thermoquad, 3,500 stall converter or stick, 3.55 to 4.10 gears, windage tray, regular pressure and volume oil pump... you'll run elevens.
