I realize that one now has to add more oil for the filter and remote lines. Thanks for responding.

Zacctly, I have 2 "stock 5 quart" pans in the shop that I took off known engines, they are front sump pans, 5 quart capacity. If you put one on your workbench, level it best as you can, then add water by the quart, you'll see 5 quarts will pretty much fill the "sump" part, oil level will "generally" be an inch or a little more below the top of the sump part, before it gets on the flat rear portion of the pan.

To fill one of these pans to the block mating surface, you'd probably need 10 quarts!!!!!!!!

Some later model ford pans had one large sump in the front and a smaller sump in the rear, these were used mostly on large passenger cars (cop cars) and 4x4's....

If I'm not 100% sure of the capacity, I check it with water before installing it on the engine, in your case that is not possible right now and without the original dipstick your not sure. I'm guessing you have a "standard" 5 quart pan, maybe if you could post some pictures that would be helpful, if not try to find out what vehicle (year/make/model) the original engine came out of and that would help you to determine the pan capacity.....
