625 street demon swap from 2 bbl

[67dodgedartconv]

I have a 273 2bbl from auto Trans car I am swapping out for a 318 with factory 360 4bbl manifold and heads. Wanting to put 625 street demon on new engine. If anyone has done this, what mods to old 2 bbl carb linkage did you have to make? I do have a factory small block 4 bbl throttle pressure rod to replace the old 2 bbl one. Thanks for any help.

the 2bbl linkage will be the wrong size. I think all you need is a 4bbl top rod or fabricate one.
