Hi guys,

I have a brand new 1406 Edelbrock with adapters in a box and I'm wondering if I should keep it for my Bird (I have a potential buyer).

Three options.

1) install the 1406

2) sell the 1406 and get a rebuilt Autoline carb from Rockauto.

3) get a rebuild kit and rebuild my original carb.

Which solution is the best according to your experience ?

Shoot !!!

To me the Edelbrock is far superior to the original Autolite 4100. I've used both and for performance and reliability I would go with the Edelbrock 1406.

Option #1. You will not be disappointed.

Hi John:

so, for XMAS, wifey was kind enough to order me an Edelbrock 1406 for my '61 T-Bird. Since I found this quote, you must be familiar with this. I did the install last night and got stuck because the accelerator shaft does not align with the Ford Throttle adapter and does not work correct. The angle is off so it's not working. Are you familiar with this, and if so, how do I deal with it? Any recommendations? Should I try to change out the accelerator shaft? I can provide pics in a little bit...

I don't use any adapter. As you can see by the picture I just put the accelerator rod through the hole and use clips on the back side to hold it. This is on a Squarebird but your '61 should be similar. You may have to adjust the rod slightly to get full travel.

Ok! Then I probably then don't need that adapter they sold me (it was only a few bucks. I will see if I can get that to work today!

I'll post when done.

Hi John:

To what did you hook the spring into? I am thinking I need to modify theseparate piece that the autolite had on it to take the spring...

I used the same piece. You can see it in the picture. It's on the same bolt as the Autolite.

These 1406's have an electric choke. I need to run the (+) to a key-activated source. Current wire not long enough to feed back to the fuse box. Is there a key-activated (+) under the hood somewhere other than the generator and the coil? I don't want to plug into either of those. I see what I think is a CVR on the firewall right in the middle of the firewall, and I'm thinking that may be a good place, but I cannot find a diagram showing exactly what that is.

Any suggestions?

If you have power windows you can hook it to the window relay that's on the firewall. The only down side is that the choke will have power with the key in the ACC position also. If you don't have power windows I would run a wire to the fuse box or ignition switch.

Hi John:

Yes, I found an opening in the firewall where I can feed a wire through and I will be plugging into the fuse box. I just need to go get some additional wire. I'll splice and dice and be good.

I started her up earlier and man o' man, does a new carb make a huge difference. Proper acceleration curve, all the good "sounds". Just need to get that wire attached, and tune her up.

I have a new distributor and timing chain to work on, but for now, this will do. Thanks for all your help and happy new year.

I'm sure you'll be happy with the new carb. It does make a big difference in my opinion. Plus they are designed for todays' fuels where the old Autolite wasn't.

Since I am now going to more modern equipment, we are going hot rodding! LOL! New Billet Distributor next on the list as well as new timing chain.

John, thanks for all of your advice and counsel. With that new Edelbrock 1406, my acceleration issue is gone. I am just now playing with the air/idle screws to find the best settings. now we're cooking with gas.

Glad to hear that the new carb is working out. Even though I've adjusted the mixture screws many times by feel I prefer to use a vacuum gauge to get it just right.

I was just logging in to post the same Jopizz.

Does he know about the cam button vs thrust plate for timing sets ?

Ok, a man's got to know his limitations. New Edelbrock 1406 w/electric choke, under the new Edelbrock chrome 14" Air Cleaner Assembly, new Pertronix Distributor w/Ignitor II sparked by new chrome Flamethrower II Coil, freshly painted coil bracket to boot.

I spoke with Bob's Carbs in Oceanside, along with 2 other mechanic friends of mine, and they said "that autolite is 56 years old, and you may finally get it to run better, but you will never get it to run like new. Rip it out and throw on a new carb."

Sage advice. I have a consistent, safe acceleration curve, 18Hg vacuum, right on the money, running to a PCV on the Edelbrock 1406 (it has 3 vacuum ports: Ported, Manifold and PCV). No more carb spacer, everything as it should be.

Timed to 6 degress BTDC, per the manual, and it stays constant.

Starts up on first crank, even when cold. Went for a long shake down today.....wow....
