Yes, the Ford  Autolite 1.08 that Ted included in his random carb tests on his 312 + test mule, some time back, scored better than several of the larger carbs in the tests. It was likely originally off of an early 289 Mustang.  The newer Holley 465 was even somewhat better & very near the top of the 16 carbs tested. All this was documented in a Y-Blk Magazine article..  However, note that the Autolite 1.12 did not test near as well.

The Ford/Autolite (flattops) carbs are simply getting much harder to find and especially those that haven’t been rebuilt several times.  The 1.08" series are even harder to find than the 1.12" series.  Those carbs tend to get damaged on the rebuilds by over-tightening some of the fasteners and this makes these carbs a tuning nightmare.  Prices on good used units are now exceeding the price of brand new carbs so it becomes questionable to sink that kind of money into a fifty plus year old carburetor.
 
The new Summit carbs shares internal design features with the older Ford/Autolite design and uses Holley replacement parts for the jets, needle seats, accelerator diaphragm, and secondary parts.  Being available in both 600 cfm and 750 cfm varieties makes them well suited for a wide range of applications.

Not that it matters, but the Summit carb looks much more like a Holley 4010 / 4011 than an Autolite 4100.
