Default Ignition graph

Hi. My engine is 383 with 07-467-8 Comp cam ,ported heads & intake ,freeflow exhaust,42 injectors , 3.54 Dana 44 & high performance 4l60 made by Pete Kane with 2800 stall converter. I tuned my engine with the help of C.A.T.S.tuner . I changed volumetric efficency, idle speed , etc, all parameters I need this engine work. But I didn't change ignition graph. One man told me , that after changing cam I need to change ignition graph too. I could'n t find graphs anywere....May be somebody have these graphs for me to understand , what changes I need to do....
Now I have 12.78 1/4 mile on 315 conventional tires. It seems to me not very good result.

What intake are you going with? Those are some pretty hunkin injectors for your 383. When I was running a 383 I had 30lb injectors and was running 11 teens. Ignition should run 22-25 at idle and max at 32-33 at wot around 2800-3000 rpm. At cruise, you can run 45-50 degrees with minimal load. Just fill in the rest. Willie
