Hmm, that is odd. I've never seen a solid lifter engine from Ford that oiled the lifters, but I guess that just reminds me to never say never with a Ford.
Hey Mr. BH,
Hmm, is right! You may have opened a whole NEW can of worms here. Permit me to respond to the rest of your very thoughtful post, and then tell you another part of this conundrum.
As you can see in this pictures below of a 427 solid lifter block, the main oil passage is in the top center of the block (hence topoiler or centeroiler). This feeds everything but the #1 main and cam bearings. At the back of the block, this is connected to the lifter oiling passage by drilling down diagonally from that main passage. Obviously on this solid lifter block it has not been done.
I see that.
In the second picture you can see on the back of the block that the lifter oiling passages were never drilled either.
I see that too.
I have known others to have oil pressure problems when running the OEM style dumbbell lifters in a hydraulic block. Now obviously there are still other drilled passages that get plugs. But generally speaking solid lifter blocks are not drilled for lifter oiling.
Actually, Ms. American didn't get the the Solid Lifters you refer to as the OEM style "dumbell" Lifters. Here's the story on that: The Lexington Machine Shop in Houston did all the machining work on the 3.14's Block. They said that they X-Rayed it, and found the Cylinders EXACTLY centered, and they commented that it could be bored out to be 427 with no problems. They align bored it (.030), and rebuilt the Heads. They obtained the Cam (A Crane Fireball), and "specified" the Lifters that were to be obtained by me. I took that specification to the Auto Parts store, and as previously mentioned, had to go pick up the Lifters. What followed was the getting of the Nash Rambler Lifters. But they were not in any way a "dumbell" shape.
Many seal off the passages, or put restrictors in place to limit the amount of oil that goes through.
We didn't do anything other than install a "cup" shaped plug that got swaged into the Oil Gallery bores after we found that the old Gal's NEWLY rebuilt Engine was only putting up 30 PSI.
Strangely, the first thing that was suspected was that we had gotten a "wimp" Oil Pump, and THAT was the first thing we changed. Still couldn't get sufficient Oil Pressure.
So... (and here is where the "can of worms" comes in): The way we found that it was the Oil Galleries that were not plugged, was that we used a stethescope and listened to the Engine running, and could hear the Oil beating against the Timing Chain Cover! Yes! The Timing Chain Cover!
Permit a bit of an explanation about THAT. We had to take off the Timing Chain Cover to plug the Oil Galleries.
Now, looking at your second JPG, it shows the BACK of the Block with the Oil Gallery Bosses at 10:00 and 2:00 O'Clock. But if I recall correctly, the Oil Gallery on the 3.14's Engine were at 9:00 and 3:00 O'Clock, and were most certainly at the FRONT of the Engine.
Back in 1989, I had only built one other Engine, and that was Lorrie Van Haul's Mighty 225 Slant Six (a sweet little Engine if ever there was one). So I was a novice at that kind of thing. I was being mentored by Howard Williams, the uncle of Ernie Lozano, who owned Ernie's Motors in Houston, and he was letting me do the work in his shop under the watchful eye of uncle Howard who had, when he was younger been a Line Chief for Holman Moody Pit Crews. So being a rank newbie at this sort of thing, I didn't know anything about Oil Galleries, but Howard did. Strangely, when we got the Block from Lexington, Howard actually commented on how nicely it had been done, and how clean the Oil Galleries were! And afterward, he was quite chagrinned to have noticed that, but didn't snap to the fact that they needed to be plugged!
Looking at your JPGs, the thought occurs to me that if the Oil Galleries were drilled to the Front, that one would have to go through the Distributor Bore. I'm sure we would have noticed that.
So this brings me to a question, as I am still a dilettante mechanic. Where are the Oil Galleries on a Solid Lifter Side Oiler FE? Could it be that Ms. American's P-Code Engine is a vaunted Side Oiler?
Makes me want to go "Hmmm" again.
