I should add that this top rod for 74 up is non adjustable and that the bottom rod is adjustable at the tranny. Up to 73 the top rod was adjustable. Kim

I believe if u use a cruise control cable bracket u can bend how u need and everything lines up pretty close. I think there is another taller cruise bracket but I don’t think I have it. Kim
Here are some more pics too, 4 bbl bracket in blue, 2 bbl brackets in gray.
Here 360 with Edelbrock 4bbl on 8022 alum intake D100 Truck with 727 trans, with the 4 bbl bracket. Real happy how the kickdown worked here and the road speeds associated with it.

To answer your question , yes, the 318/360 2bbl and 340 , 4bbl are different in many ways and so is the kickdown lever . You can change the bracketry or go with a Lokar system . the Lokar system eliminates the b.s. factory brackets (something the factory should have in the first place) basically trouble free . sometimes the factory changed brackets every year and/or body style , crazy .

So like many I don’t have full throttle travel.
Is this a 2 barrel bracket ? It’s 4 3/4 on the top. Is the 4 barrel
one wider on top? Found them on Classic Ind.

And I'm pretty sure the 68-70 340 AVS A Body throttle bracket is different than the 71-74 340-360 Thermoquad A body throttle bracket. The TQ has more throttle travel than the AVS does. The throttle cables are also different between the AVS and the TQ. I have modified many 2 bbl linkages to work on various 4 bbl swaps. I won't ever buy a cable kit. I kind of feel, if you can't make a mechanical linkage look nice and work correctly, maybe you should just buy a Chevy.
Having done this myself many times, it appears to be a two barrel bracket bent to fit. Look at the second pic where the cable hold down is. You can see where the original 90 degree bend is.

That’s what I thought. I’m guessing the 340 one will put the cable hold further up. Messed with it and can’t seem to get the cable (19 3/4)in the right place.
Thanks

So the 340 one is side ways ?

When using the 318 2 bbl bracket, you need to cut the cable holddown part off, move forward 3/4-1 inch turn it vertical and tack weld it. I use a 10-12 inch piece of all thread clamped in the cable bracket, that way you can align it perfectly with the carb stud. You will probably need a small pc of steel filler welded on the bottom of the throttle bracket. I can make these look nice, grind down the welds and paint. No one has ever questioned my brackets. I usually build these brackets on the bench with the manifold right in front of me or when building the whole setup with trans mounted on the engine. I just sit in a chair, a lot easier that leaning over the fender. But then again, I have a few 5 gal buckets of linkages to cut up and use.
It the new 1 posted. It will save u a lot of headaches. Kim
The 340 bracket is what you need. All A-Body throttle brackets are the same, 68-73, except some manual transmission brackets do not have the kickdown pin.
Here is the complete setup for 4 bbl applications.
