Good to hear it run right isn't it? If all went smooth, I would start looking for extra parts I forgot.
Back in December VA provided me with a fancy set of ear plugs. I went to a tractor pull all excited that I could carry on conversation again. Next pit they fired up a 5 engine blown modified. Hearing aids shut off the sound until he shut it off. I decided then I would put them in my pocket (in the bag provided) until the possible loud noises were over. That way I don't drop them some place where they don't belong. Imagine if they went down a carb or hit running fan blades. (and with them out you have an excuse if you ignore the wife or some other).
I sold my '66 Fairlane 3 years ago. Wish I had it back. I sure miss that old hot rod. If you put all that work into this one and then sell it when you get the bugs worked out, I think you will have lots of second guesses too.
