I recently got a '92 460 long block and I was about to prime the oil pump when I remembered to put the oil filter on. Well I tried but I couldn't because there is some kind of adapter threaded into the block. It take an 1 1/4 socket to take it off and it has no stud in the center to thread the filter on instead it has female threads. What do I need to set this up for the standard truck filter installation?

 

There is a cast housing that fits on the block, and is secured to it by a large hollow bolt - hence the female threads. A large O-ring seals it to the block.
The casting redirects the filter forward and down. Most have 2 tapped and threaded bosses for installing oil cooler lines; many of those are plugged.
The casting has the proper threaded stud and machined surface for mounting the oil filter.
You can see them on E-bay occasionally. In fact, there are 3 on right now as I write this. They are for different applications, so make sure you get the right one - with the bolt too. Search for "Ford 460 oil" to bring them up.

 

you can also pull that adapter off of a 5.0 mustang or linclon, or look for a 370/429 in a medium duty truck they use the same one, or you can go to your local ford dealer or parts house (sometimes) or machine shop and get the right adapter for just putting the oil filter on if you don't need to redirect your oil filter for clearance purposes. Most machine shops, or at least good ones will put new threaded adapters in the blocks when they work on them just for safety sake and keep some on hand, my machine shop buy his from the local ford dealer.

 

Well I know this seems like a simple problem but it is getting complicated. I went to the dealer and ordered an oil filter adapter. When it came in it turned out to be the female adapter that threads into the block with internal threads. Well I already had that. Then I told him I need the male adapter that the filter spins on to and when that came in it fit the filter fine but it is way to small to thread into the block. It does however fit the female adapter fine but the female adapter has a shoulder on it that is too tall to allow the filter to seat against the block. I am missing a part here somewhere but what is it? By the way thanks for your patience on this one.
