No diff.
Hi, they are the same, only autos have the kick down linkage.

Thanks Mike and 68c15. I will keep hunting for the auto version since I have a auto tranny. No rush here its gonna be a while before I can build the 327.

I have swapped many Q jets around, there was no differences at all that will prevent you from bolting either version on either engine/tranny combo. Chevy used the same carbs but just added a connection for the kickdown cable in an allready available hole in the throttle arm. Ford was bad about that, you had to have a auto trans carb to work on a auto trans car/truck.

No pictures, sorry. You can make one yourself if you cant find one in a junkyard. There should be plenty on any chevy truck, they used mostly Quadrajets or Rochestor Dual jets(just the primaries of a quadrajet).
