| 3.91:1 rear and a plain Performer? |

That intake is an oinker. It stinks for performance. If you want to see any benefits with that 750DP, you must upgrade to a Performer RPM.
I assume you've got a 9.5:1 compression car engine, not an 8.5:1 pickup truck 390. The extra compression of the car will be good for the 750, but you really need to add a cam kit (includes cam, lifters, valve springs, and you'll soon learn the valve spring retainers and valves also gotta go if upgraded) if you wish any balance in performance.
Double pumpers have a nice feel, but they also suck a lot of gas. In your present build, you'll se mileage drop, but you will not see performance improve, since you are bottlenecked in other areas.
It seems to me some FPA headers which port-match C8AE-H heads, a cam kit, and an RPM intake would make that Galaxie ready for that 750DP. Mileage would still drop, but performance will climb. 650 would also be a fine carb.
JMO,
