Paul,
That cam is very aggressive for the street, are you intending to race it?It is also a mechanical cam, needs to be adusted every 500 to 1500 miles, a hydraulic cam goes for years without adjustment. A cam with 230 to 244 degrees would be better suited to a normal cruising / fun cobra. Also stay around .530 to .580 lift , anything over 600 is hard on valve springs, unless you want to change them every year. Mr Fixit is right ,a smaller cam IS faster for a street car.
