Well, since nobody else has answered this, I guess I'll throw my two cents' worth in. For a street cam that you probably aren't going to race with a whole lot, aim for something around 260 degrees advertised duration, not much (if any) over .500" lift, and 110 degrees lobe separation. That should give you good low and midrange grunt, and a slight lope to the idle. The more duration the cam has, the rougher the idle, and the higher in the rpm band the max horsepower comes in at. Check Comp Cams catalog. They have several cams and kits for the later Chevy engines, but the specs should give you an idea what to have your cam grinder duplicate.
