Any carb recommendations?

[Hevy]

Besides installing efi does anyone have a brand of carburetor that they prefer?
I have a 1984 c10 with a 305. It used to stumble quite a bit in cold weather until warm, now it stumbles no matter the temperature and seems to have a dead spot at around 1/4 throttle.
It's starting to get a bit annoying and I have to really wait until the coast is clear or it could die altogether when pulling out.
Any recommendations will be appreciated!
