This will be a thread to document the 460 swap I'm doing in a 78 Bronco. I know the forum is Bullnose focused but the 460 came from a 86 Bullnose so hoping that may qualify me :nabble_smiley_wink:

I have 2 other threads discussing some work done to prepare the 460 for the swap.

Hopefully by reading this thread, it will be clear what worked, what did not work.

For now, the 460 is installed. The following had to be changed to suit the 78 Bronco for now

- Motor mounts .. Trans Dapt 4225 Motor Mount. This is a simple design and it has good reviews. It is a solid mount however, so i'll have to see how it works. It's an Econo-choice, so if I don't like it I can later upgrade.

- Oil filter .. I 'deleted' the oil filter adapter and the oil cooler that the Bullnose trucks used and I installed a Allstar Performance Oil Filter Adapter SBF ALL92003 to install the oil filter straight to the block. It says its for a Small block, but the threads and everything work just fine on a 460.

- At this point in time, I will retain all the accessory brackets/belts that the 460 came with from the donor truck. Will update later if things work, don't work.

Today the 460 was installed in the Bronco with a C6 behind it. The motor mounts fought me a little, but even factory stock mounts put up a bit of a fight, so nothing too bad. Wife was gracious enough to help, and with some finagling the 460 fit just fine.

Looking good! And no worries about it being a 78 Bronco. We are a family and even some of our moderators don't have a Bullnose to their name. :nabble_smiley_wink:

I like the documentation that tells what you've done so you, and others, can get back to it if need be. (Try that on Facebook.) Detail it out and, at some point, put it in a document.

Thanks Gary! You sound like my ex-boss who wanted me to put everything in a document!

Documentation is not my strength. I do something and move on to the next thing. All my previous projects were undocumented so much so I forget what I did 'back then', so this ability to document here is wonderful. I'll take advantage of that :nabble_smiley_wink:

Jim will object if you do as I've done and create a Word document and imbed it. That way you can edit it in the background and it'll be evergreen on the forum.

But you can just edit some post, like the first post of your thread, to keep the documentation up to date.

OK good to know, I'll try that!! I don't have word on my personal computer unfortunately. Maybe use Wordpad.

If you use something like Word or Wordpad then you'll need to either embed the file, which causes Jim problems, or cut and paste the results into a post.

Instead I'd learn to use the editing tools here. With work you can do a bulleted list or a numbered list right here in Nabble.

I can't object, if I can't see it..... 🙄

The filter adapter is D7AZ6890A

They're like $3.95 from the mother ship.

This thread really should be in 'Projects'.

ETA: if you search that # you also come up with https://regismanufacturing.com/ford-302-351-1968-96-oil-filter-adapter-fa-302/

Thanks for that part number!!

Called the local dealer with both F1AZ6890B and D7AZ6890A and I thought it was funny that they said "this is a GM part we don't carry it"... I told them.. "hey.. have you ever seen a GM part starting with an F1AZ and D7AZ ??? You should know better!!"

Anyways, Regis manufacturing is ~25 mins from where I am. Glad to know they are there!!

I do agree this thread belongs in projects 100%, is there anyway to move this there WHOLE ?
