"Rockdriller, the compressor had an overhaul tag on it as well. I dont know anything about the application though. It looks like it uses pressurized oil from the engine, but thats a guess. It came with a new carb, aircleaner and 2 massive looking motor mounts, and a new fan blade. I will take more pics when I get back out there."

You're correct.....that compressor is oiled by the same port that would lube your turbo.
I'll try to find a pic. of mine.

Very nice set-up.

Abus:
I checked my treasure pile, and I think I have a stand for your 478, complete/w surge tank, gauge panel and murphy gauges.
I can send some pics pm with some measurements before you head this way next time to be sure. If it will fit, it's yours. I'll never use it again.
I welded some temperary mounts on it to runin some 350s & 348s. Easy to knock off with a torch and do no harm to it.

It's one of the bolt together, so if your short on space, we can knock it down so all pieces will lay flat to get home.

I took a few more pics. It was overcast so quality isnt the best.

Thanks, I will let you know when I am headed that direction. It will more than likely be Thanksgiving or Christmas plus or minus a week. Murphy switches, I havent seen a set of those in a while! This is off topic but you wouldnt happen to have a set of steel "oneway" or sometimes called "diskall" wheels in your treasure pile would you?

abus...

That thing is great.
I would love to get my hands on an air cleaner like that.
I haven't seen one like it.
If anyone has or knows where to get one...lemme know.

Thx for the pics, abus.

Rockdriller
The label on it indicates that it is a "cyclopac" built by Donaldson. I did a search for the part number but didnt come up with anything usefull. They are still in business though. It might be worth a phone call if your interested.

I'll do that.

Now that were through the Holidays and some of the more demanding chores are behind us, it looks like I might finally get the 478 into the shop.
It was wonderful to meet up with Cayoterun and his wife over the Christmas holidays. We got to hear the V12 pickup project run, WOW. I had forgotten how those motors shook the ground, it was awsome! We talked motors, shared stories, and walked through a lifetime of treasures. Thanks to their generosity, I now have a rolling engine run stand so, once I get it flushed out and cleaned up I will start posting some pics and we'll see if we cant breathe some life into the beast.

NOW, get in gear, and let us hear your old 478 breath fire, thunder, and rattle the shop windows. I'm sure it will bring back many memories of hearing those old engines roaring day and night pumping water back when we were much younger. I'm sure you've changed about 40 water tubes from an open ditch, the water got ahead of you, then the ditch broke. Great fun trying to plug the hole, Huh?

What always amazed me, and still does, is how long those things would run between overhauls. I was never around one that had an hour meter on it, but wish I had. Wish I knew. We tried to estimate them on this V12, but no way to be real accurate, so tried to be conservative. Conservative truth will raise enough eye-brows, and see the questioning looks on people's faces. Makes you wonder if your "honesty" factor hadn't just fell in the sewer in their minds.

Hope you don't find any serious snafu's on your motor as you get further along.
