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...

You are so right,Roger..It could have been far worse.. Glad that you have found the cause of that oilpump seizure..I have never seen an oil pump drive twist like that before..Quite startling.. It would look good polished up as a trophy,mate.. .. Hey,,if ya drive through the night,,you might catch up with the rest of the Grey Beards..

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.

Probably why my engine builder has told me to get a heavy duty one for the 347W.. The 302 in the truck was reco'ed about 20 years ago,,and is still all stock throughout,,apart from a very mild cam..I think I will leave it alone until I need to do a rebuild.. hehe
