I just installed a large log head on my 1965 mustang with the 200 I6. I also picked up a Carter YFA which I plan to use in place of the Autolite 1100. The large log head has a carburetor bore of 1 3/4" vs. the 1 7/16" of the small log head. So the bore on the carb spacer for the Autolite is about 1/4" too small. I had thought about boring out the original carb spacer, but I'm not sure there's enough metal. And if I mount the Carter YFA directly to the manifold, it will be turned sideways so I'm not sure the throttle linkage will hook up. Are their other options?
