Sorry we do not offer this carburetor in a manual choke version. We do have a similar carb in a 600 CFM version with a manual choke as part number 4251850.

This Holley carburetor includes the Ford automatic kick down brackets for use on C-4, C-6 transmissions. However this Ford kick down bracket will not work with the Ford AOD transmissions as this uses a Throttle Valve cable to control transmission line pressure. You will need to purchase the carburetor bracket separately to mount the throttle valve to the carburetor.

This carburetor will work with the 700R transmission by using kickdown cable bracket under Holley number 20-95 and stud under Holley number 20-2, 20-38, or 20-40. This carb will NOT work with any other overdrive automatic GM transmission.

Yes this carburetor will work fine on your engine. If you have a stock intake manifold which is made for a Quadrajet carburetor then you will need adapter 3252697 to bolt this carburetor to you engine.

You will need to check to see if your intake manifold has a square bore carburetor bolt pattern (such as this Holley carb) or a spread bore bolt pattern (such as a Quadrajet carb). Square bore bolt pattern measures 5 1/8" x 5 5/8". Spread bore bolt pattern measures 4 1/4" x 5 5/8". Adapter part number 3252696 can be used to install this carburetor on a spread bore intake manifold.

Throttle hook up is per the instructions and depending on your transmission you will likely need a kickdown cable as well as the kickdown cable bracket 20-95 if you have an automatic transmission.
