Thanks for the input! I like not only knowing the difference, but also why!

Hopefully - the box also says G.M.C., not Ford.

Between the two:

Flange gasket, throttle body gasket, and air horn gaskets are the same.

Fuel valve (a.k.a. needle & seat), accelerator pump, idle mixture screws, main metering jets, and economizer valve are different.

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.

Thanks Carbking… I think it had a couple of part numbers on the box, I will have to look and see what exact models it fits. I didn’t know there were several of the “same” carb…

Actually, a few more than "several"; I have 125 different listings in my database for the AA-1 plus another 56 different of the type 2100-DD that most folks erroneously call a "94". This is the type Jerry mentioned that he installed on his modified Ford.

Hope the kit you have works for you.

Jon.
