True, it could be a pooch carb, which is why I asked if it had been gone thru recently and what had been done to it. With tuning , it can be made to work. Aint rocket science, but its not "forgiving" as Holley said. To Dave Rays' point, the engine may need some tuning to optimize it for the DP. Vac secs can be way more forgiving. BUT, back to the OPs request...
BTW, here's some rocket science, from true carb gurus... for the OP's "edumacation" on air bleeds, PVs , which holes the cams are affixed thru and even the size of the channel the PV opens to makes a difference.....

"Nice looking setup !
I did this same swap of my DP body for an HP body to get air bleeds and choke horn delete. I have a wideband in my '70 SS396. The larger IFR (.033) in the Quick Fuel red DP upgrade metering blocks was perfect. It solved my tip-in stumble. For air bleeds, I started going big, then, ended loving the small -- HSAB - 25 to 31; LSAB - 68 to 72. This improves gas mileage. (Right now, I am debating between 27 and 31 for the LSAB, and settled on 68 for the LSAB). 68 LSAB will not lean out the IFR and give me plenty of transition gas for overdrive on the fwy - idle is at a perfect 14.2 for my cam, with approx 1 turn of the idle mixture screws. I also ended up with a larger PVR (larger than the stock .059 - I drilled the next size up), high flow power valve, and 9.5 rating even though I have a 292H Cam (high duration). This large PVR and quick opening PV allowed me to go to 72 on the front jets. Rear jets are around 83, 84. The smaller HSABs (25 to 31) will make everything richer on the top end and leaner in the mid-range, so, you need a good, quick opening PVR to avoid going lean in the mid-range. I also ended up with the blue cam on hole 2 for the front and the black cam (hole 1) for the rear. 31 nozzle with extensions in the front and 35 nozzle in the rear with extensions."
But you wont need to be that involved to get it to work! Great carb tuning thread to learn from though.. Read on, and TUNE. Or punt and get a 3310.
