Any ideas when the change from 2366S to 2366SA occurred for 1956 single four barrel cars (both Corvette and passenger car).
The latest carb tag I have seen for a 2366S is dated B 6 (February, 1956) and the earliest 2366SA carb tag I have seen is dated F 6 (June, 1956).
I figure the change occurred between those two dates (notice that brilliant detective work).
Just would like to narrow it down further.
FYI: Regarding single four barrel intake manifolds, the latest date code I have see for the 3837109 intake is F 14 6. The earliest date code I have seen for the 3735448 intake is G 6 6. The 448 intake replaced the 109 intake late in the 56 model year for single four barrel applications.
