Do you have a q-jet?
If so there is a screw under the electric choke to adjust the choke idle speed.
The screws faces the front of the truck like the idle speed screws on the drivers side.
Its a little hidden under the choke, you may need to look at it from the passenger side or straight from the front with the air cleaner off.

Go out when its cold, pump the gas twice, pop the hood and start it up.
If the choke idle speed is so low that it will not idle on its own.
Then turn the choke idle speed screw a turn and try starting it again.
I do not recall if clockwise makes the choke speed slower or faster.
Once you can get the truck to idle on its own you can set the choke idle speed to whatever you want.
With the truck in gear 900-1000 rpm isnt bad, you could even go a little higher if your truck needs it.
Some set their choke idle as high as 1500 rpm.
While setting the choke idle speed do not change the regular idle speed.
Take the truck for a long drive and let it fully warmed up.
If you are not happy with your idle speed now, then adjust the regular idle speed screw. You may have to adjust your choke speed one more time the next morning depending on how much you had to change your regular idle speed.

There is also a screw above the electric choke that faces the top of the windshield (this may only be on the Edelbrock Qjets). I am not sure what this one does, but I adjusted a little bit one time and it seemed to smooth out the idle a bit.
