I stand corrected about a 2150 is a 2150.
I bow to your school of hard knocks route.
Changing linkage on the carb is no problem for me.
With that being said I am still wondering which is the best carb to get.
My engine is now basically a stock 302.
Shame I could not use my spare as I had just finished rebuilding it and
putting in the dizzy vacuum advance. All I had left to do is make the feedback
solenoid blockoff plate with the mixture screws.
But....I depend on this truck and when you are doing a bunch of jerryrigging....
You have to know when to say when....and I say that is now.
If I did not depend on it I would pursue it just to see if possible......
And believe me I am well versed in the AOD connections.
Still doing research on which is the best one to go with...so...
Am open to any.... hopefully educated .....opinions.
Yep..they are like bellybuttons everyone has one.....
Just hope I get the right one....
Thanks to all for the input.
Didn't mean to start any bs.......

I would look for a carb off a truck with no EGR. However, that may not be possible since the 2150 was introduced at about the same time as EGR was - 1973. But, the early emissions regs didn't apply to the heavier vehicles, so maybe pickups were exempt, or maybe F250's were exempt. However, the smaller engines with the 1.08" carb weren't typically used in the heavier vehicles, so it may be a fruitless search - although I would try if it were my truck.

Exactly. And then two things happen:

1.) The victim will spend the $$$ to rebuild the AOD, and then they will quickly destroy it AGAIN unless they realize that the AOD TV rod is not compatible with the Ford kickdown linkage. And you can't depend on the transmission shop to find the problem, because most don't know *anything* about carburetors anymore, the carburetor looks stock, and the TV rod hooks right up to the Ford kickdown linkage, so...

2.) After the second rebuild and subsequent failure, the victim will conclude that the Ford AOD is "junk." THAT is one reason why the AOD has such a bad reputation.

I agree with Gary. If you are going to stay with a 2V carburetor, I would highly recommend an earlier Autolite 2100. The Autolite 2100 is an older, simpler version of the later Motorcraft 2150 you have now. There is nothing made aftermarket today that can beat the simplicity, reliability, or drivability of the Ford Autolite 2100/Motorcraft 2150 and Autolite 4100 4V series carburetors.

An older (pre-1979) 1.08 Motorcraft 2150 will work great too; you will just need to re-curve your distributor to work without the EGR.

Swap your throttle linkage from your stock carburetor to the replacement and you won't regret it. You may even pick up some extra power.

Good Luck!

I second the suggestion to find an Autolite 2100. I am going to be putting that carburetor on my 302, and its because I wanted a simple reliable carb.


That's some interesting info on AOD linkages, hats off to Fonzie, he is very knowledgeable with these trucks' details.
