Still gathering parts for my 390 build(390/40 over/4.125 stroker, cruiser/highway wagon). I searched the forum for oil pumps to see if anything shook out as what most people are using. Seems Milodon is one that came up a good bit.
Should I lean towards a high volume unit, or is an OEM pump suitable for what I'm doing?
-
I recommend this pump.
The Melling M57HV.
If you want a really nice one get the M57HV from Precision.

This pump will read about 80 to 85 psi cold on start up and settle out around 65 psi when hot at 2000ish rpm.
Get a heavy duty drive shaft and you will have all the oil pumping you will need.
I like a mechanical gauge with a hard line to the gauge.
Do not use the plastic line that comes in the box.
-
Yeah, I'm a fan of HV pumps and thinner oil.
For my oil psi gauges, I use -4 SS line to the gauge. Edelbrock has a lil 1/8inch X -4JIC adapter that hooks into a gauge easily.

In this day and age "thinner" oil can be a multi-viscosity a 10w-40. Do you run a low viscosity oil or multi-viscosity?

Should I use restrictors in the heads with the high volume pump?
-
I do and it makes me laugh how much oil is still up there.
-
I use Melling HV pumps and have had excellent service out of them.
In my 351Cs I run VR-1 30wt or 10w-30, both have the same oil pressure and bearings look the same on teardowns. It's usually 10w-30 because it's stocked locally and straight 30wt is special order.

I use restrictors in my Ed heads. I tapped the oil passage for a 1/4" 20 set screw and drilled the set screw
with a 0.070" hole. I have LOTS of oil up to the rockers.

*cough cough*
WELL, if you'd bought the FE intake comparo book, you'd note the oil level info in the back shows you all ya need to know about that.
Just messing Chief, but I think Jay has videos online with an oil sightglass in the pan with and without restrictors. Made a believer out of me.

Man, I am drowning in info as it is! I appreciate the heads up though!

Is that with restrictors?

Yes, that is with restrictors. There is another video, which I think is the one that Drew was referring to, where I have a sight tube installed on the oil pan, and you can see the oil level in the pan going down during the dyno pull. Can't find that one at the moment...

Here is a good overview of pumps and other oiling options for the FE: http://fordfe.info/Forum/Oil.html
-
Looking at the Figure 1 there, there are only 2 oil feed passages in the heads(1 per head)?

Correct, one oil passage to each head and that feeds the rocker shaft.
The passage in the head is where you put the restrictor in.
Funny thing about Edelbrock heads. The oil return areas are smaller than Ford iron heads.
I did a little blurb on opening them up a little bit ago.

Reading through your thread, I'm not clear on what you did to the oil drainback holes.
Did you drill them out to the smaller end to 1/2"?

Reading it myself I'm not clear either. ::)
I would have drilled the oil return hole bigger for sure.
At least out to 1/2".
Next time I have the covers off I will measure and rewrite my gibberish.
You also want to smooth out the little valley at each end. A small burr in the die grinder
will make quick work of that.

I can't understand the infatuation here on restricting oil to the heads/rockers. Oil draining from the heads through the designated holes at the ends of the heads is relatively variable at low rpm/low oil pressure the oil held in each head varies from zero to a few ounces as it drains away to I'd estimate a quart at max pressure/rpm. Once the max level is attained "in the heads" it simply flows in bulk over/through the intake down into the lifter valley. It can not exceed that set level since it's a waterfall. The most oil that will ever be in each head can never exceed 1qt. The two quarts being held in the heads is a given. When filling the motor with oil you need only to plan on two quarts residing in the heads when the motors running. I understand valve springs especially when running high spring pressure and high lift get really hot (I witnessed Smokey's Spintron heat/spin the springs as he sent the vales into float). There's graphs around that show how much spring pressure is lost per unit of heat in the springs, obviously there is also a relationship to heat and valve spring life. Oil is essentially the only way to remove heat from springs - if there's nothing but mist around the springs get hot. One example is burning the hell out of your finger tips when bending a paper clip to break it. With Teflon seal's oil is not getting past them.
Finally if you've ever studied FoMoCo FE rockers and Shafts you know there's numerous holes and passages that index to jet oil at the rocker tips, spray the springs and pressurize the rocker/shaft bearing surface. You start reducing all that engineered oiling and ???

Perhaps it's asking too much if one would carefully read this and also understand it.
