Ideas for new carb?

Hey guys... Im having all kinds of trouble with my Quadrajet carb... someone decided it was a great idea to wire the choke open, plug off most of the vacuum lines and generally mis adjust everything from the idle to the kickdown cable...sooooo my plan is to replace the carb... looking for suggestions... rt now it is a bone stock 305. Will be adding this week Hooker headers and eventually putting a 350 in it. so ... do we just replace carb? carb and intake? thoughts and ideas?? Any other info you guys need? It is my DD but considering gas here is .... 0.78 a gallon.. mileage isnt really a concern... oh yeah i said 0.78 cents a gallon for 98 octane.

Put a 600 vacuum secondary Holley on an adapter plate now. Wait for 350 to get manifold and you can use carb there also

Wait....What?

Seventy eight cents a gallon? Omega? I'm taking a wild guess here that you and the car are not in Arkansas. That would make getting it made right a real challenge.

A direct replacement carb is available and would be the easiest fix if getting parts is a challenge. If you change the carb type, hoses and linkage can be a challenge with a NAPA next door. Have you found drawings for the correct routing of the vacuum hoses if you are going to replace them?

Keep us up to date with what you do and remember, pictures help.

The 1406 carb from Edelbrock comes set up for economy.

A holley may produce more power, but the Edelbrock is very easy to maintain.

if u make sure the carb is clean inside. and get the vacume lines all hooked up. you should be able to adjust the choke correctly. check float hieght. their stubborn carbs sometimes, but until you get them happy you wont be.

Check out Sean Murphy Induction at http://www.smicarburetor.com/, he built my Q-Jet and I'm pretty happy with it.
