That sheet is from June 2022
If you look at the pix of the setup, you will see that there is NO provision for the hot idle solenoid, its mounting boss and drilled and tapped holes, yet the center carb's throttle linkage has the hot idle adjustment arm. I wonder if the manifold casting company (Edelbrock or "Eddy") just forgot to include this solenoid mounting boss. If one is building or restoring a six barrel car to origional appearance, the hot idle solenoid is important aspect. If not, it doesn't matter.....just my opinion of course....
There is a used set up that needs some TLC but might be worth a look. FOR SALE - Complete 6 pack intake and air cleaner set up
The specs of the origional carbs were: end units were rated at 500 CFM; the center carb was rated at 355 CFM. The replacement/reproduction center carb has smaller throttle bores and venturii size. In addition, the reproduction units ALL come with fuel bowl vent connection and vent valve, where as pre 1971 cars used a flap type bowl vent open to atmosphere. All of the reproduction units have hex head bowl retaining screws, where the origional bowl screws were different head profile and have a slotted head. The replacement/reproduction units fit and function as the origional design but MAY need rejetted depending on the engine's cam, compression ratio, vehicle's rear gear ratio, transmission, spark advance characteristics and intended use.......just my opinion of course....
What you see in my old '70 automatic set pictures above is what is needed to run vacuum secondaries.
IMO, in my neck of the woods, yep.
The throttle brackets are different. Do a search. You'll see the rest will be different as well. Get the correct components that work together.
