Requested oiling mod info

-
Ok, that’s what I thought. At this point I don’t have any oil there. It’s blocked by a set screw under the #1 main bearing. I’m considering tubing that gallery too, so that there would be oil there (if I wanted it) and since it’s at the end of the line, I could pick up oil for the rockers right there.

I’ve never looked into tubing that side and don’t know if it would work.

Or, I could suck it up and have all the lifter bores bushed and not tube anything.
Agree, if you’re blocking one side the other needs the inside tube to stop all those little leaks
 
That’s where I’m heading at this point. But rather than have external lines, I’m thinking of drilling into the gallery that feeds the oil pressure gauge and using that to feed the rockers through the original passage in the block.

I just need to make the time to go out there and look at it real close and think it all the way through before I start drilling holes. As I see it now, the oil going to the gauge port isn’t taking oil directly off the oil gallery feeding the mains.

I really need to go do some work on that but I’ve got other things keeping me much more busy than I want to be.
If me the rockers would be the last thing that got oil like pumping oil from Ohio to Kansas, don’t tap it in Ohio tap it in Kansas
 
The cam and rocker gear are always taking oil from the mains on these engines.

Now, if you are saying to do the crossover so you can block the feed to the drivers side gallery and still feed the lifters/rockers then yes, you can do that.

That’s not the same thing as claiming it slows the velocity of the oil down so it can make the turn into the main feeds and stuff like that. That’s not true.

And even if you do the crossover, you are still pulling oil of the main feed to the main bearings. You just shortened the routing.
Yes, that is My thinking, & appears to be what is accomplished. But it is required to bring oil to main#1 when the end of the right gallery is plugged in the front, & the angle is needed to generate oil feed towards the #1main feed in the reverse direction to give it priority in the left gallery.
It would seem to Me the main feeds at the head supply positions would really just need enlarged to handle the extra demand if the pump is maintaining pressure.
 
You know, you COULD just run a lower RPM and save yourself a whole lotta work. LOL

According to the guy who’s been racing his 71 Duster since new (has given me a lot of advice) if you ain’t turning 8500 you’re on the trailer if you tangle with another E/Stocker

Then I wouldn't run E stock. Simple. lol
 
D E or F don’t matter, heavy hitters in each
Right, I understand. No doubt they're badass. Even if I had that kinda dough to mess around, I wouldn't turn those RPMs. It wouldn't be necessary for "me" to race and have a good time.
 
That’s kinda what I’m looking at. I’m thinking of clocking the cam bearings on 2 and 4 so it blocks the hole going up to the heads. I just need to spend some time looking for the right place to get oil to the rockers that doesn’t pull it off the main bearings or from the passenger side oil gallery. I already block the oil off to the lifters.

If you do not want to drill into the main oil passage in order to provide full-time to the Head you can go to the back of the inside China Wall where the oil goes up to the oil pressure sending unit drill and tap. Then put a tee fitting there and then run a braided or steel line up to the passage that feeds the heads and you would have full-time oil pressure to both heads and you would not be tapping into the main oil galley.
 
Did everybody read the pages of the book posted in the original #1 post?
They are saying if you spin your motor above 5500 then you should modify the oil system.

Their opinion. Countless engines have gone 6500 even 7K for decades and not hurt a thing. Probably not the BEST case scenario, but it's a fact.

I agree, 90% of the time it’s a bracket race till the guy in your class lines up with ya then it’s all out, first to the finish line. Then hope ya don’t go 125 under, then there will be a weight penalty added to your car

I like that. "Their opinion." LOL

They are the engineers that developed these motors. I'm sure they would value your opinion since you were also helping to design them. Wait a minute you weren't. They were. They are talking about racing an engine and after 5500 RPM you need to watch it because the engine was not designed as stock to handle high RPM on a constant basis.
