Edelbrock 1407 on stock 402

[69SCSS]

Anyone have a baseline jetting for a stock '71 402 with an Edelbrock 1407? This is what the carb has now and it's way overrich... to the point it won't idle:

Primary jets: 415
Primary rods: 7147
Secondary jets: 407

Looks like the carb came stock with 413 / 7147 setup, but this has been upped to 415's. I can't find a calibration chart for the 1407 on the web for some reason, I find lots of 1405 / 1406's though, won't really help! I need to find the combinations for the 1407 since obviously the 415's are going to drown the motor. One thing is for sure it runs great at 3000 rpm and up right now! Fouls out pretty quick under that.

Anyone have the chart or any idea what a good starting point would be?
