79gmc5.3

Im new here and Im 17 and i have a 79 GMC sierra me and my dad built together for my first vehicle and he wants me to figure stuff out on my own. we did a 5.3 swap with a carb, it has long-tubes, 600cfm edelbrock, 700r-4, msd 6010, 2000 stall. its recently developed a problem when i give a little gas just to accelerate normally it kind of stumbles and studders at about 1000rpms but clears up and seems to run fine after 1000rpms it does it worse when its cold and a little better when it warms up and almost unnoticeable when its warmer outside. Im just trying to learn and was hoping some of yall would be able to help me out, it would be very appreciated.

We checked the ignition parts already(plugs,wires,coils)

It did have a miss at one point but we fixed that

So Im guessing it something with the carb?

No carb man but sounds kinda like choke on carb not working right!

Since it is an Edelbrock carb, check to see that one or both of the fuel metering rods are not stuck or sticking.
