Today I went on a 40 mile cruise to a car show. After I got off the highway on my way there the car died & would not start. I popped the hood to look for anything obviously wrong but didn't see anything. At that point even though the car was well warmed up at that point I set the manual choke & cranked again. I was able to get the car started again & got to the show. On the way home I noticed a loud whistling sound that changed with throttle. I popped the hood again and the sound is coming from the carburetor. It seems to have a weird vacuum leak. I've never heard a carb whistle like this.Here is a short video carbwhistle.wmv

I've rebuilt this Carter AFB several times in the 36 years I've owned the car & I think it is toast & not rebuildable again. I see Autozone sells rebuilt Carter AFBs. I know some have installed Edelbrock 1406 & 1411 ( I read details in the Help section). Autozone also has Edelbrock 1906 with this description:

The 1906 AVS2 carburetor is an upgraded version of the 1406 (SKU 38901) with a new calibration for improved performance and drivability. When replacing a Quadrajet or Thermoquad Carburetor, with an aftermarket Holley, or Edelbrock. Adapter part number 5765 (SKU 228351) may be needed, to properly seal the carburetor to the stock factory intake manifold. AVS2 Series(TM). 650 cfm; Square Flange; Non-EGR; Electric choke; Satin. Universal throttle linkage type; satin finish; Non-EGR compatible. Calibrated for fuel economy. For use on pre-pollution controlled vehicles (PPCV). Not calibrated or compatible with alcohol/race or E-85 pump fuel. New fuel filter between fuel pump and carb is required. Adapter PN2696 or kit PN2697 is required. Proper installation is the responsibility of installer; May void warranty. Adapter PN2732 must be used when installing on certain intakes. Recommended CI displacement for big block dual quad apps is 396-502+ cid

Has anyone tried the 1906? It seems like it should work since it is "upgraded version of the 1406". I'm just researching which direction to go. For simplicity sake, I might just get a rebuilt Carter AFB but for a little more money might upgrade to a more modern carb.

Check the throttle shafts for wear. Look at the metering rods where it hooks up to the power piston.  

Also check the phenolic spacer below the carb. It does crack.

Kurt, If you go with the 1906 give us some feedback once installed. It would be good info for others that might want another alternative to the 1406 and 1411.

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 14 Comments

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
