2020 C1 of the Year Finalist - Unmodified
Default Holley replacement

My '66 327/300 with Powerglide and electric choke has a Holley carburator from a 1971 Ford TBird.
Lately it has been running terribly.
Can anyone tell me the model number for a plug and play edelbrock that has the correct linkage connection for the Powerglide?
Thanks,
Captain Bud

When I had my C1, keeping it original was #1 priority. With the C2, I'm not concerned. I just want it to run reliably. That's why I suggested Edelbrock.

Bud, although I love the 3367 Holley on R66, I also have a Edlebrock 1406 on the 68RS. Both are 600 cfm. Edlebrock offers two 600 cfm square bore carburetors, the 1405 and 1406. I believe either will perform well for you, however, you will have to modify the fuel line and use either an electric or manual choke.

They are very common, and I have a couple on the shelf.
If I recall, the PG rod attaches to the hole below the throttle plates on the throttle lever. A picture of what you have now would be helpful. Here are a couple to compare with:
I believe the Carter AFB also had the same throttle lever.
I believe the Carter AFB also had the same throttle lever.
The only caution is fuel in the Eldebrock seems to evaporate quicker than in the Holley and thus if you park it hot, it can be hard to start after it sets for a while even with the electric choke.
Your fuel line will probably need a 90 degree fitting pointing down to attach the line and clear the air filter base. Of course, replumbing the PCV and power brake lines will also be needed.
I agree, the properly tuned Holley 3367 is preferable as you retain the divorced choke and fuel line, but that may have already been modified on your Holley.

Holleys are quite serviceable and will maintain the proper look and fit.

There are three flavors of Holley 3367: original '66, service replacements, and then re-released 3367s in the early-2000s. I'd be on the lookout for the re-released 3367. Service and re-released carbs have 4-digit date codes. I believe this is one of the re-released flavors.

Almost any used or NOS carburetor, Holley or Carter or Eldebrock, will probably need rebuilt do to the soft parts hardening. The original accelerator pump on a AFB was leather and will shrink if not emersed in fuel. Just saying.
