625 cfm street demon carb swap on small block

I have a 273 2 bbl engine from an auto trans car I am swapping out for a 318 with 360 heads and 4 barrel manifold. Will my 273 throttle linkage work with this carb? I do have a factory 4 bbl small block throttle pressure rod to swap out for the 2bbl one, but the rest of the linkage setup is 2 bbl stuff. Will the 2bbl carb stud transfer to demon carb or do I have to order theirs? Any other mods need to be made? Hope to hear from those who have made this swap. Thanks for any help.

the short horizontle pin will bolt in to the hole in the throttle linkage and just need the 4bbl horizontle rod with the long slotted hole
