239 Y Block first Run
I'm about ready to fire my rebuilt 239 y block. Everything is ready to go. My question is about priming the oil pump. Is there a right and wrong way to do it? My neighbor thinks if we pull the coil and crank it a few times that should do it. Any suggestions? Thank you for you help.

Not 100% sure about the Y-Block, but every ford engine I have rebuilt, I have used a priming rod and a drill, and primed the engine prior to starting. If you have an extra dist, you can make a priming rod. Priming prior to turning over / starting is the best way to lube the parts prior firing.

I'll be doing the same thing with my 292.
I'll make one out of an extra 6 point socket and a LONG 1/4" drive extension. (I'm assuming you have a HEX drive....my 239 was a hex drive........if it's a blade type drive you'll have to be a little more inventive)
just be extra careful not to drop the socket into the engine after you turn it.
You don't have to spin it to 80 psi.....just enough to pressurize the system, fill the oil filter, and maybe see a little oil get to the valve train.
Cheers,
Rick

Yes, it's a HEX drive. Using a 6 point socket is a great idea. I'll tape the socket to the 1/4 drive to insure I don't drop it into the engine. I don't need that problem at this point in the game!!!! Thanks to all of you for your suggestions. They are very helpful...as always.

By the way I went out and fooled around with the socket set and discovered that a Craftsman 1/4" drive 1/4" deep socket will work and it will not fall down thru the hole. In fact, it's just long enough.
So, just put a piece of electrical tape on the socket and extension and you're good to go.
You can either use a battery powered drill or a speed wrench and crank to your hearts desire!
I did this with my 454 BBC Mercruiser and I was able to get the oil pressure up to about 15 psi using a drill. More than enough to fill the oil filter, lines and cooler.
