the stock grind in my 85 gti is a pretty good torquey low rpm cam. its all out of power by 5500. and provides good torque. well, i think it does pretty good for a gasser atleast, it has nowheres near the torque of my diesel, but you get the idea. my GTI cam would bolt right in your 3A. im not sure what # grind it is or anything, but im almost positive its a stock cam.
