Cam up my 318, help me chose!

Well, 318willrun´s description of his engin/car setup got me thinking...I can't lay any rubber behind me, maybe my car is overcammed as it sits... it´s about 11-12 seconds to 100km/h and really slow from a start, but it pulls quite good to 6000 or above. I bought the car with the setup as it is, and the previous owner told me that it is the stock cam... any good tips to check that without tearing everything apart?
Also my goal with the car is a street/hot street car for recreation and fun.
Thanks for all the input, all discussion with you makes me learn a lot!
