Carter AFB replacement

[Roger H.]

My 1965 with 327-300 still has the original carburetor. It has been rebuilt, but it might be time for a change. Has anyone found a suitable replacement for the AFB that will still accept the original air cleaner?

Re: Carter AFB replacement

Isn't the new Eldelbrock carburetor just a rebranded AFB design from 60 years ago? Get one with a detached choke and check the fuel line connection.

With that said, why is it "time for a change" for the original? It's designed for your engine and if rebuilt properly will probably perform the best.

I do understand the fun with tinkering with different carburetors (I have three for my Corvette), and having a spare can be handy at times.

Re: Carter AFB replacement

Thanks for the info Mark. I'd like to use the original. It might just be time for another rebuild.

Re: Carter AFB replacement

Thank you Chris. I'm getting lots of good advice here. My car is mostly original under the hood. I'd like to keep it that way.

Re: Carter AFB replacement

The top of your existing stock AFB carburetor - the air horn - will fit onto a new Edelbrock Performer carburetor. You can buy a new Edelbrock and swap air horns. That way you get a new carburetor, and all your stock '65 stuff will bolt up. Linkage, choke, gasoline line, and air filter.

Of course, you may not need a new carburetor. But if your heart is set on a new one. This'll work.

Mr. Ritchie, Thanks for the input. I hadn't considered that option. If I can't get the original carb working to my satisfaction, I will try replacing it and swapping parts.

What a great option for cars with an AFB carburetor.

It's curious Eldelbrock chose the AFB for their current line of carburetors. The design is from the 50s. From a street performance perspective, the Q-Jet is a better architecture. Yes, it's spread bore design is limited to mostly GM cars but that's a large market.

Re: Carter AFB replacement

Roger,

The AFB is a very good carburetor and well worth saving. Get a pro to bush the throttle bores (if needed) and overhaul it.
