The 263 in the '41 had to go to an electric fan, because the '52 263 and maybe all 263's fan was relocated by moving it down and forward, making the engine assembly slightly longer than the 248. The engine sits at the same or very similar height to the 248, so there is no carb. height problem in this car. I don't see that it would be a problem in the newer models that an air filter change wouldn't solve.
