Someone please help me



First, I want to say I like the project, and hang in there you'll get it figured out. There is a lot of good help here on FABO.

Second, I was looking at your pictures, and I do not see any kick down linkage on the carb. Your 727 will not last long without it unless you have a manual valvebody.

This will need corrected before driving. I'm an old fart, so maybe I just don't see it. If you don't have it, or the original linkage won't fit the mustang, you can use a cable setup.
