What is the largest filter I can use?

The best bet is to run a FL299 which is 1.5 inches longer and the same in all other respects, but probably a thicker can since it is longer. But the FL299 is expensive at the dealer. I order the Purolator version (L40017) for $6 at Advance Auto and they have it the next day. This particular Purolator has the Motorcraft-style threaded end bypass valve too.

TallPaul is right! Here's a list of larger filters, including the FL-299. I've cut open "virgin" filters and measured the surface area of the filter element. TP did the same with the Purolator, which I don't have on my list... perhaps he'll post it, as well.
Here's the list:
The thing to remember is that surface area is not all there is to the filtering ability of a filter... the element material is at least as important (if not more).
Here's the list:
Code:
Pleat # Element Surface
Depth Pleats Width Area
Motorcraft FL-299 0.750 64 5.50 528.00
Fram PH977A 0.656 56 5.69 418.03
Baldwin BT251 0.750 51 5.38 411.19
Donaldson P550299 0.625 60 5.00 375.00
Wix 51773 0.688 49 5.13 345.30
For Comparison (standard OEM size):
Motorcraft FL-1A 0.719 56 3.75 301.88

Thanks for posting your list Big O Dave. I tried to link to the Oil Guy site and it would not work. Here is my Purolator L40017 data (used filter vs Big O Dave's were new) next to Dave's FL-299 data:
BTW, someone at this site a couple years ago posted that the longer FL299 was spec for IIRC an '89 F850 with 460 V8 (among many other years and models obviously).
I use the L40017 on my motorhome and sometimes on my 300 I6. Not to leave the very good FL1A behind, I am running that on the Aerostar 3.0, which specs a FL400.
Code:
Filter Pleat #Pleats Element Element Depth Width Area FL-299 0.750 64 5.50 528.00 L40017 0.719 66 5.38 511.00
