This has been a real interesting study in persistence, Roger. Probably frustration too from your standpoint. Thanks.

Jack, in my haste I misplaced the decimal on the dimensions, 0.390" OD and 0.290" ID and 0.050 thick, a spacer for a 1/4" bolt. You'd have probably guided me to the source if I'd posted it right.
To close the loop, after a couple of stutter steps with the distributor I lit it off this morning, got the timing set and played with the idle stop adjustment a bit and it seems to be just fine. It holds a strong 25# of oil pressure at hot idle, and at 3000rpm holds a strong 50#. It sounds stronger than it was before the incident, due I'm sure to the fact that cylinders 6&7 had vacuum leaks due to the intake gasket splitting at the corners. The Good Lord was my Co-pilot Saturday, and quick action on the loss of pressure saved the engine. One new standard volume oil pump, two new lifters for #1 cylinder, a new pump drive shaft, some gaskets and an oil change plus a few days of frustration. Could have been sooooooooo much worse...Roger
Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.

There was someone holding your hand alright!
That is very good news indeed.
When I first read of this incident I promptly thought the worst, and that you'd be looking at a complete engine rebuild; but quick action on your part by shutting everything down and opting for a piggy-back ride home, although embarrassing and annoying/frustrating, saved the day.
I'm really pleased for you mate!
You should chromium plate that drive, mount it in a frame, and call it 'My Hard Luck Trophy to Myself.'
And it's no good you buying a lottery ticket this month; you've used your quota of good luck!

I'll chime in with my .02 personal experience with a 302.
The pickup looked a lot like yours, and the screen had a hole in the middle which presses against the pickup bottom. I cleaned the pickup to re use it, as I had always done, and got a tad rough with it and popped the screen in, exposing the hole.
Well I popped the screen back out, thinking I was fine.
Apparently, once they pop in, they will do it again under regular operating conditions.
I found this out, the same time I found out that I missed a piece of nylon from the cam sprocket. The pump seized, and the dizzy pin sheared.
A lot of guys with ample rebuild budget will automatically replace the pickup, and a lot of people reuse them. But, if the screen gets popped in, It's trash..
Education is expensive. Keep that in mind, and you'll never be terribly upset when a project goes awry.

If you Google 'small block Ford twisted oil pump shaft' you'll see photos of dozens. It's apparently not an unusual problem with small block Fords.Jack
