That is your camshaft timing card. It gives you the parameters for the valve timing ,opening and closing, duration ,valve lift, valve overlap,etc. This is built into this particular cam. The only variable is when the cam is installed is to advance it for more low end or retard it for more top end performance. This is a mild street cam so it's best installed straight up. The mechanical timing in your distributor is a separate thing. It's best to pull the distributor out and put it on a distributor machine and spin it up to get the exact advance curve. The springs and weights in the distributor can be changed to vary the timing and curve. You will want 20 to 22 degrees advance all in by 2,500 rpm in the distributor. Add that to the 10 degrees initial and that gives you 32 degrees total timing. That is a safe advance for todays pump gas.
