OK as you have pictured, there is no electric choke on the Edelbrock carb, and the manual choke Butterfly in the front appears to be wired open. So that means no choke on startup.

2nd, the geometry on your throttle and transmission kickdown linkage is way off, moving the kickdown linkage in the opposite direction because it is hooked up below the the throttle shaft pivot and should be above it to get the right push on the kickdown as you are opening the throttle.
See the Factory Mopar Linkage pictured below.
Also you need the Edelbrock to Mopar linkage adapter too, to get your throttle cable and kickdown linkage mounts in the right spots. They are like 15 dollars.
