I also found on the NAPA site that the same cartridge shown is used for 1960-1962 F-350 with 292.

Air cleaners like that were used on the F-500 trucks with 2 bbl carbs

That's an idea.  I took in the old filter and NAPA sold me this new one.  Still have the box so numbers, yes.

if the filter has any numbers you could look that up and see if any y-blocks are on the list.

This is an AC that came with the recently acquired 312.  I like its proportions and simplicity so am cleaning it up to put to use.  It was very dirty and rusty prior to the cleanup, like it had been around a long time.  The filter housing is 10+ in. in dia. and 4 in. tall.  The filter is 9.25 diam and 3.5 in. tall.  Any idea what it originally came on?  It looks too tall for a car, and all the stock filters I have seen, truck or car, have been oil bath.
