'71 318 Auto 2-bbl to 4-bbl

The easiest way is to use a 4 bbl throttle bracket. But you can modify the 2 bbl bracket to fit. I did but I had to change the geometry for the kickdown rod to make it work correctly.

Here you got a link about the subject. At the bottom of the thread is how I did my 2 bbl bracket fit to a 4 bbl carb. It's another carb and intake I have but I suppose you can use that info to modify yours also.
