Didn't see this part earlier. I'm using stock ford injectors, not the performance models. Between that and the mallory distributor I gained about 2.5mpg improvement. I forget the exact part numbers I'm running though, a LOT of the ford injetors fit.

Went from 10.5 to 13mpg. Though we're back to the ethanol enriched around here again, so that knocked me back to 12mpg for the winter.

In more practical terms, I went from 150 miles per tank to 185 or so. This is with a SW top and huge winch bumper + winch.

Maybe he's a she, and doesn't like being called a he?

Hmm well that is a lot of sludge biuld of you got there, thats indicative of years of neglect (bad oil / infrequent oil changes?) Could it be a porous block due to the over heating? Did you check to make sure no sleeves dropped or move around? Probably could use a good oil flush with some type of circulating cleaner.

going outside now to drop the slump and see how bad the caked up sludge is.

then flush the radiator, run a hose through it and flush it again, then park in on an incline and fill it up. I know remember that when we filled the radiator back up the front wheels were completely deflated so we could get into the engine bay easier. So I hope I just have an air bubble at the back of the engine.

Update: Changed oil and dropped the slump to find it really clean! Flushed coolant and filled it on a big incline so that coolant could move to the back of the engine.

Now I noticed something when driving back 4 hours to NY. On a long downhill on the highway I would pop the truck into neutral for 300-500 yard so it was at 1700rpm idle. Then as the decent would start to flatten out I would rev it up once to 2500ish and slip it into 5th gear and would notice instantly that the temp would go from 205ish to 190 or below!

Now is it doing this because the engine is cooling itself at idle speed while 75mph air is going through the radiator? Or is my fan catching when I pop it into 5th and instantly cooling it down? Water pump spinning faster?

The drop happens so fast that it really can't be just the truck running at idle for 500 yards, because I would see it gradually go down. this is more like POP into 5th and BAM! 10-20 degrees cooler.

Thanks again for the help you guys & sorry to dig this back up.

May be a long shot but are you sure your gauge is well grounded?

I was having some really weird things happen to my temp a while back. I finally noticed that when I turned the headlights on it got hotter. It ended up being the stock ground.

Probably wont be, but it is an easy fix.
