Actually, the 223 would not exactly be a bolt-in swap without some modifications for the motor mounts. If I remember right, the 215 motor mount bosses are located further toward the back of the engine compared to the 223 because the 215 has the distributor located in that area. Thus, the fuel pump on the 215 is closer to the front of the engine compared to the 223. It's as if the distributor and fuel pump traded places when the 223 came out in '54. Bottom line is; you would only need motor mount modifications and redo some fuel system tubing for the different fuel pump location.
If it helps any; the 223 engines were mfg from 1954 thru 1964 and I believe in the later years it was only offered in pickup trucks till '64 due to the engine being phased out.
During that era, they were offering the new 170cu in and 200cu in engines in cars like the Falcons, the mid-sized Fairlanes and Mustang Pony.
Sorry don't know anything about those nor the 262.
