1957 was the very first year, in 1957 it ( the 600 CFM version) was used on 312 V8's, in 1958 a special version was created and only used on the Mercury '383 High Torque' engine it flowed 669 CFM ( not for bad for a factory stock carb! In 1963 another special version was made the ' High Performance 4100' affectionately nicknamed the 4100 HI PO it flowed 600 CFM and featured a manual choke (except the 63-64 Fairlanes, 63 Meteors and 64 Comets which had automatic chokes). This carb was used from 1963 to 1967. It was used on Fairlanes, Comets, Meteors, Mustangs, (was also used as a service replacement in 1967) and Shelby Hertz cars.
In 1964 1/2 the smaller 480 CFM version was introduced, and the 480 is the only size 4V carb used on the 289 except for the HI PO 289 engines which featured the HI PO 4100. The Autolite 4100 was used on 289's, 352's, 390's and 428's until 1966 and on a few 428's through 1968 ( virtually all Ford cars of the late 50's, and mid 60's that had 4V carbs from the Factory had Autoite 4100's. The Autolite 4300 ( latter to become the Motor craft 4350) replaced the 4100 in 1967 due to increased emissions requirements.The regular 600 CFM version was used on 352's, 390's, and 428's possibly a Mercury 410, or even some 360's too but I don't know for sure. The 600 CFM version was used also in Full sized Fords and Mercurys.1966 Ford Galaxie 500 convertible with 4 wheel manual drum brakes, 352 Cubic Inch Ford Edsel V8, 600 CFM 4v Autolite 4100 Carb, Cruise-O-Matic FX 3 speed automatic transmisson, Ford Nine Inch with 3:1 ratio, and dual Trush Turbo flow Glass packs. Mechanicaly its mostly a factory orginal car.Ed Jenkins. Only thing I can say for sure is that all 360 engines were 2V truck engines, so they wouldn't have had the 4100, unless they kept the '4100' name for a 2 barrel carb.On a side note, I have a 4100, and I'm interested in using it in my truck when I rebuild my 390.How can you tell what cfm the carb is without a tag?HI! That is right, the carb maybe the Autolite 2100 series, used up to 1974 and replaced with motorcraft 2150 series carb, both were two-bbl units.

Holley made 2-bbl 500 series for Heavy Duty 361/391 FT engines. Only thing I can say for sure is that all 360 engines were 2V truck engines, so they wouldn't have had the 4100, unless they kept the '4100' name for a 2 barrel carb.On a side note, I have a 4100, and I'm interested in using it in my truck when I rebuild my 390.How can you tell what cfm the carb is without a tag?Yes, the mercury cyclone got the 4100 autolite instead of the holley that year. Don't know why, I can only think that the holley must have required more tinkering, and Mercury was thought of as a higher class car, meaning less tinkering. I know this, since I've talked wtih 5 other cyclone owners with Gt motors of the 1967 vintage, and they all have 4100's sitting on top.

The Autolite 4300 was a Ford carburetor manufactured from 1967 through 1974. These carburetors were produced as an emissions-compliant replacement for the previous Autolite 4100 model, and were later superseded by the Motorcraft 4350. Both the 4300A and 4300D are unique by virtue of having spread bore throttle plate designs that are unique to these carburetors and their relative intake mainfolds. The Model 4300 Carburetor is designed to supply a calibrated fuel-air mixture to a V-8 engine. In normal operation, each of the primary venturis sup plies all the fuel,air mixture required by four cylin ders.
