is the 63 autolites a colder plug? if so then those plug's will probably look a little darker with the same jetting, as a colder plug disapates heat more quickly, if I was in your position I think I would leave the jetting alone untill you can get to a track and make a pass and click the motor off just after the stripe to get a true reading, then jet for MPH and that may actually be smaller jet's. 
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

You are taking a chance when you shut off your engine or go into neutral with a 727 at the finish line.
The trans can spin up internally and blow up the front drum like they do on the line after an overrunning clutch failure.
It may not happen to you but it can and has.
Some guys have had that happen when the engine blows at the top end and stops turning.
Sorry this is not related to this post but it is a safety issue so I had to speak up.

What carb? You can get hundreds of opinions on carb setting, and jetting for these holley carbs...But I gotta suggest, go to the Holley web site look up the listing, and the factory jetting is a great baseline to start at believe it or not.... If you dont like power valves, just take out the front PV and jet the recc up by 6 jet sizes or so.. Also 90% of the time, a flat spot is a lean condition in my experience... Its almost impossible to fine tune a carb on the street. Go to the track and tune for the best MPH, make one change at a time, and make a few passes before making any changes.

Your the first person I have ever heard say that  I have used and race 727 trans. from B&M,Art Carr, A1, Torqueflyte Specialities, Pro Trans, Turbo Action and others. None of them have ever said, unless it had a low band apply valve body, to not put it in nuetral after crossing the finish line I have seen racers (and done it myself) put the car into reverse after crossing the finish line and wreck there cars and or blow the motors up. I was lucky when I did it, I managed to get it out of reverse quick enough to live and tell about it without hurting anything major  Please elaborate on what your saying  BTW, I don't put the car into nuetral anymore after crossing the finish line, once was enough
