It doesn't make the cam bigger, just more intense. It will open the valve faster. The rocker ratio does add lift, but thats not exactly bigger. Bigger mostly goes with duration. Thats how I read bigger anyways.
Also an extra point of compresion is only about 3 - 5 % at this level.
I think you can turn a mid 11 with the power. Chassis, weight, suspention, converter and tire size are big bennifiters or detractors. I can't help at this point. Theres not enuff info and you'll have to fuss with dailing it in.
