Holley 3310 jetting for 360

I have a 66 Cuda with a 360. CompCam 280 Magnum cam and 9.5 compression. The 3310 runs rich(plugs are black) with stock from Holley 3310. The Holley 600 1850 carb on it runs great(plugs not rich) but low on top end power. I would like to run the 3310 for better power. What jets and tuning have you found good on a 3310 setup like this.
Thanks
