autolite 4300A & autolite 2100 1.14 2bbl

<!-- / icon and ***le --> <!-- message --> i found a nice autolite 4300A Square Bore at the s**** metal yard today but it has NO NUMBERS anywhere, only a "V" with an "o" in it's center inside of a circular casting stamp on the top of the carb, p***engers-side of the fuel inlet. i'm trying to find out the CFM and applications of this carb.

ALSO: i found an autolite 2100 2bbl carb with a 1.14 marking which means that it's a 300cfm. would this be too much carb for a chevy 235 six that's .30 overbore with a solid cam?

 

There should be some numbers on the left corner of the mounting flange, right by the hole for the stud; example, 3A AB. That two barrel should work ok on a smaller engine, but jets are kind of scarce.

 

Stock carb for mid-60s Mustangs with the 289.

anyone know of a more efficient better gas\ milage carb to upgrade from my OEM ford autolite 2100 2bbl carb with a 1.14.?
I have a 1964-1/2 Ford MustangK-code (Hi pro)coupe with a 260 (4.3 litre) V8 iron block and manifold all original. Confirmed right on the vin and ***le and original dealer manifestfrom Windsor. Thanks

 

yeah I know but... I'd like to get as good gas milage as our Kia and Saturn, both get close to 40 mpg no exaggeration. Thanks

 

Jet it down a little, Holley jets will work, might help.

 

Holley jets have a different thread pith and do not work.

 

They work in my Ford flat tops, maybe not in Autolites ??
