Choose one head porter and have them design a matching cam.

Gary, what kind of heads and valvetrain do you have in your car and what does it run?

It looks like AI is worth about .3-.4 sec over most competing combos but it is not going to make any b-body an 11 sec car without a lot of extra effort and weight reduction.

I would love to see a 4300+ heads/cam/stroker b-body on (drag) radial tires and a street suspension run below 12.3 seconds in non-freezing weather.
