fazels,WELCOME!!!! to the BB.There are as many carbs choices as there are opinions.A 2BBL may give you some economy but mostly simce you cannot open the throttle up.An engine is an Air Pump and as such the more air you put in the more fuel you put in.4 bbl carbs tend to have smaller primaries so flow less air and use less fuel until the rear 2 bbl's are opened up.
The choice of carbs really depends on several factros.Total engine combo,trans, gear ratio,use of truck and area all may play a role in the proper choice.In order to get the best info you need to include some of this info in your post.
There are many knowledgeable people here who will be glad to discuss the choices and options with you to help you decide .
On the disc brake question,i can't help except to tell you some members have done a disc swap.I believe there is a write up on a couple of different ways to be found in the FAQ's.If you go to this link

Welcome from Texas...

I agree on the 2 barrel vs 4 barrel option. A lot of folks like the 2 barrel but I prefer a 4 barrel for the reason PanelDeland mentions.

I've only used quadrajets since I'm familiar with them, but gotta warn you, there's a lot of people that hate them. They're not the easiest to work on but they are plentiful. Once you have them working right, they basically are trouble free.

Vacuum operated secondaries come only into play when you step on it so basically you only use 2 barrels while cruising. The primaries are generally smaller than 2 barrel carbs.

I agree with the Q-jet. They are plentiful in the salvage yards & swap meets. If you can learn to o-haul one yourself or drink beer with someone who can you can get one real cheap. Most Chev. engines in that era have a spread bore manifold to acept the Q-jet carb. or there are many choices available. The factory aluminum intakes from the 305 engines in pass. cars in the 80's are plentiful & work good.

Edelbrock 1406 seems to be a popular choice. Manual choke version is the 1405. These are both 4 barrel carbs. The only 2 barrel I've had success with is the Holley 500. I agree on the gas mileage issue. 4 barrel has the potential for better mileage. 2 barrels are simpler and somewhat easier to rebuild.

here is my setup. i went with the performer intake and edel 1406 carb. Seems to be a common choice here on the board.

Edelbrock 1406. Bolt on and go.

I like Holleys and have lots of experience with them. You can make them efficient by installing a black spring in the vacuum seconday (of a 4 barrel Holley). That way, the secondaries will never open all the way, leaving you essentially a 2 barrel, and if later you decide that fuel economy is irrelevant, stick another spring in there and away you go.

It's really a personal decision on that one. If it has the choke on the instrument panel some prefer the original look and use a manual choke. Some like the convenience of automatic. I have a manual on my 68 GMC and an auto on my V8 converted 69 Chevy. Like them both.

[72chevyk10]

if you go with a edelbrock get the electric choke the 1406 is specificly tuned for economy on a 350.

[mclairmo]

I would go with an electric choke for ease of installation and ease of use. My Camaro has a manual choke 3310 750 CFM Holley and I hate that choke. My truck currently has a manual choke and I hate it, too, it is getting an electric choke 600 CFM Holley. I am considering adding an electric choke to my Camaro.
