Carb recommendation 440

Hello all,
I just purchased a 73’ Dart that was setup for the 1/4 mile. I’m looking to make it primarily a fast street car, but I don’t plan on racing it. Unfortunately, I have a limited amount of info on the build.
Here’s what I know:
Weiland Team G intake manifold (single plane)
Roller cams, 10:1 compression, 3500 Stall, ported, 8 3/4 rear with 4:11, currently has a dominator 1050 on it. Previous owner said 550hp range. I took it for a slow-medium cruise for about 2 miles and used about 2 gallons of gas. The slow and medium speeds are crazy sluggish.

I was thinking about a Holley avenger 770 with vacuum secondaries or a 750 classic holley with vacuum.

I am also entertaining the idea of the Holley sniper efi. Thoughts?

If I left out important info, please let me know. I am new to the hobby and have a lot yet to learn.

My 2 cents. If you decide on like a Holley Sniper, then use a Edelbrock Performer RPM. If not, then keep the Team G. Get a lower stall TC, 2400 - 2700. Change carb to a Holley 4160 0-80508. Rear gears - 3.55 or 3.73. Sniper is the best EFI system out there. It can control timing and fans.
