Sorry to be pedantic, Denny; and, I expect that Pre 68 Dave will correct me, but 1941-1949 235s had closer bolts, the same as used on all 216s (and even earlier engines).
1950 and later 235s had the wider bolt placement.
So, the carb could be from a pre-54 216 (used in cars and trucks) or from a pre-50 235 (used in trucks). Visa-versa on the manifold: most likely it came from a 50 or later 235 used on a car or truck.
Either way (and either explanation) the carb does not match the manifold.
