Topic: Autolite/Holley 1940 carburetor

[Josep]

Hi there,

My pony has an Autolite/Holley 1940 D0PF-Y carburetor. It looks like it's not the original Autolite 1100 that Ford had originally mounted on my car back in 66, so not concours correct, but why this Autolite/Holley authorized carburetor by Ford was replacing the standard Autolite 1100..? Due to internal/design problems.? What made this 1940 model a so common replacement carb for Mustangs.? Why many people changed from the standard 1100 to the 1940 model.?

Thanks,

Josep

Possibly due to Ford no longer carrying the earlier version when they were replaced. Ford was constantly changing inventory and what they were carrying for service parts, one of the reasons the MPC versions often don't show what was originally on a car but what was available to purchase when the parts book was published

This allowed Ford to make parts that would fit more cars and models and reduce inventory while saving money. 

If we had the access and time I'm fairly sure we could search through Ford books and find where the model 1940 D0PF-Y  in 70's was listed as the replacement. BTW a number of holly models were used as replacements for V8 Autolite also

The entire February 1970 issue of Shop Tips is dedicated to the 1940 carbs.

They were introduced strictly as a service part, not used as an assembly line carb.
