They used the load-o-matic up through 1956 on V8 engines with some applications even longer but not all have the same spring settings inside. The 0BA distributor was common in 1951 and was still mated with the 8BA type carburetor and had the aluminum front timing cover with the bearing surface for the end of the distributor shaft. All of the 8BA engines were basically timed the same way.

The ECG-5 carb (1955 272 cid 94 variant) may have had a different amount of vacuum draw for the Y-block engines but I'd have to go into distributor specs in my old Motors Manual to see what differences there may be, It's not uncommon to find 8BA family engines with bits from all sorts of different applications within the era. Salvage yard specials abound for older cars that stayed in service longer than average.

By 1973, I was having problems finding certain parts for my old hand me down 51 Mercury. There are more parts available now than there were back then thank God.
