Early a kickdown set up ?
Just took a complete look at the linkage on my 65 valiant which is an original commando car & its identical to drawing I posted. Only change affecting kickdown that i've made is it now has a 4 hole spacer on manifold & attaches to a eddy 600cfm carb.Still had the original carter 4bbl on with this linkage when I first bought her so mine at least is same as 2bbl but with early mopars there could definately be different factory setups between 2 & 4bbl 273's out there.
