That fitting was used on the first of the EFI 460s for throttle body heat, then for some unknown reason continued only on 460s with E4OD. The Windsor engines I have seen had the source for the heat on the heater supply elbow and it seems the return went to the heater return hose through a tee.
The picture I posted is of a Windsor engine.

Interesting. So, what would be the purpose of that? The only reason I can see is to warm up the transmission fluid in the cooler, as a small amount of warm coolant from the heater core (before the radiator opens) will route to that radiator fitting. Which is right above the transmission cooler.
Picked up some black-oxide nyloc nuts and got the screws cut today, so here's a mockup of them installed. (The nut on the left is holding the insulator on.)
And, I found two vacuum motors that work, and several that don't, and taped the snorkels to take 14-20 and cut two more screws down to hold the vacuum motors:
So, I hope to get the base, snorkels, screws, and washers powder coated soon and get it assembled.
Well, hmmmm. Things didn't go quite so well today for Big Blue's record of leaping tall buildings with a single bound. The next door neighbor had lost the top part of his maple tree that sits close to our property line, and asked if I thought "we" could pull the remainder out of the ground. Since he has a brand new Chevy 2500HD diesel I said "Maybe - let's try."
Turned out he thought Big Blue would be more capable than his truck, so we hitched him up to the tree and I took off - only to stop quickly and do a bit of spinning. He said that he thinks the very top of the tree moved an inch, but from where it split on down nothing moved.
However, the TrueTrac diff's did their job - there are 4 patches of rubber on the driveway about 8" wide and 8" long.
As for Mother Nature, yesterday Big Blue looked at me after he pulled the sign down and said "Is that all you've got?" Today I distinctly heard "Is that all you've got", but in a woman's voice.
You would have liked the tree removal we did at the scout camp, the crew working on a very dead oak tree couldn't get it down. Camp ranger asked if I would help, he was on the Ford Tractor with a front end loader and backhoe. They were trying to push it over, and using somebody's 4WD truck to pull. I was in the camp's 5 ton flatbed cornbinder, 4 speed granny low and 2 speed rear. I told they crew (OA members) to get the chain they were using as high up the tree as they could, then Dan (ranger) and I strung out as much chain and wire rope as we could to reduce the angle (they had it short and even with the cornbinder pulling it would lift the rear axle to the point of no traction. After it was rigged, Dan took the tractor and rammed the tree as high as he could reach while I did a running start. We had the boys stand clear and I had one adult down range to let me know if it started over so I could kepp the cornbinder floored so it wouldn't hit me. Came out first run!
