| Early CJs got a 5-quart stick, later a 6-quart. |

Early CJs got a 5-quart dip stick (just like a 390 stick, but chromed at the handle), but the CJ was too fast for the standard front sump pan and five quarts was not enough.
Ford's economical solution to this warranty issue was to implement a TSB which added one more quart of oil to the pan. This was accomplished by "recalibrating" (shortening) the CJ dipstick to show "full" at six quarts.
It doesn't matter how much oil is in the lines and external cooler, just make sure you don't stop filling until the stick says "FULL". When it says "FULL" then you'll know the proper amount of oil to add next time.
Frankly, the 428CJ is just "too fast" for a plain FE oil pan. If you plan to run run a strong FE motor, you're gonna hafta buy a baffled pan (with the trap doors) and matching oil pickup, as the stock pan loses it's oil too quickly when it all gets sloshed to the rear of the engine on a hard acceleration.
Fortunately the windage tray permits the pan's oil reserve it to slosh to the rear of the engine without getting frothed-up too much by the crank, but unfortunately the oil pickup starts pumping air into the oil passages, quickly galling the bearings and other important stuff. Also, the lifters start to clack amazingly quickly when air is drawn in.
Note that high-capacity aluminum pans look better than anything else out there, but they don't handle road-scuffs as well as a steel pan (they sometimes shatter). If your original pan has a road-dent in it, you might strongly consider a sheet-steel racing pan. A nice "T" pan will hold extra oil, will baffle it to stay where it belongs under hard acceleration, and will not affect ground clearance the way a deep pan will.
