Qft carburetor help

Run a blue or green cam up front, pink cams are slow. A little more engine info would help.

I idle at 950 and slightly lower in gear. 408stroker, edelbrock rpm air gap intake, 904 trans, 3.73 rear. What else would you like to know. How do I know if I'm getting my shot to soon or to late for my engine
