well...I have a stupid question and I don't know where my shop manual is.

I have a 70's 5.0 and the distributor was out because the engine is on the stand. It has been sitting for a while and i decided I would work on it today.

Anyways I flip teh motor over to put the oil pan on and the oil pump drive shaft came out of the distributor hole. It is kind of pointed on one side and flat on the other.

I need to put it back in now...which side goes down into the block? The flat or pointed side...(I think pointed)

thanks guys.

The side with the collar goes toward the distributor, so that when you pull the dist out of the motor, the shaft doesn't pull up with it and then fall into the oil pan.

I would say the point would go up to aid lining it up with the dizzy, but it shouldnta fell out either

For starters, back in the 70's Ford did not make a 5.0 liter, they made a god damn 302!

Now, the oil pump drive shaft is usually just a piece of hexagonal rod, used to look like a long piece of allen-wrench stock. With the higher volume oil pumps you will see some stronger rods that are round with the hex drives machined on to the ends.
The shorter section goes into the pump, and the longer one should have the collar or (sometimes washer-looking gizmo) on it. Usually the collar is packaged with the rod but not installed. It has been known to happen that the original installer will leave out the collar, so that part may be gone.

There is no collar on this one, just the hexagonal shaft. One end is pointed, the other is flat. Should this have a collar?

no collar, but it has a pressed on type washer deal, kinda like the clips that holds brake rotors on the car during assembly. it keeps the shaft from falling out when you turn the motor upside down, the narrowed end should go towards the dizzy. this helps when stabbing the dizzy.
