You and I disagree on very little. It’s just the cause and effect part where we differ. I would assume that anyone who starts to modify the oil passages already knows the basics like inlet and pan etc. This isn’t done for a daily driver. I am not a follower. Never done the crossover thing. I...

I am not going to get into your oil timing. I addressed that to you 3 years ago and you have Sanborns notes. Slotting the bearing shells and the bearing saddle fixes that. If you can’t understand the velocity issue, you won’t understand what slotting those bearings is doing either.

All I can say is what Jada said. It is beyond you to understand. You understand how to correct the problem. You understand the leaks at the lifters being a problem. You don’t understand the why. And I don’t know how else to explain it to you. Yes Glidden was a mortal man. The true test of any...

The Chev does not have the velocity problem because it has 3 dedicated galleys. All 3 of them are plugged at the end of the run. The chev does not share valvetrain and lifter oiling with the crankshaft oiling. The Chrysler due to its design, tries to oil 16 lifters. The drivers side galley gets...

Show me another way to feed the drivers side.

Both of these mods are designed to cut or restrict oil to the lifters. That’s a given. No argument from me there. There is just more than one way to do it. I agree with you that installing a crossover tube and nothing else is not effective. I took the time to email you Sanborns notes. Please...

In your last paragraph you say the front oil boss is for dry sump. Yes you could use it that way, if class rules allow. You say that in front oiling, that all the oil is from one feed, unless you pull the oil off before it gets to the main. Well you have Sanborns notes. You pull the feed out of...

Velocity is just another word for excessive flow or speed if you will.The crossover line does supply oil to the other side and if done right only slows the oil at #3&4 main, the majority of the speed is killed by the front setscrew. When you tube the passenger galley, it cuts the leaks to the...

Why do you think Chrysler designed front oiling bosses right into the casting of the “X” and “R” blocks if they thought it was not beneficial. The guy made you a simple drawing which is representative of the small block and asked you to explain why you are saying two columns of oil won’t flow...

Ah there is probably a reason that yellow rose has come back on the forum with a new name. Can you guess what it is. lol

I have to agree. And how much oil pressure is at #1 main that is trying to feed a cam bearing and 8 lifters with a 9/32 oil passage.

If a guy put in a crossover tube and nothing else, then the modification was not done right and it’s not effective. I give Rapid Robert credit because it sounds like he is trying to do it right and he knew enough to ask about the angles of the fitting. That mod has been around so long,that some...

When you push the brake pedal on your car, after the pads hit the rotor you have pressure, but no flow because it’s a sealed system. An engine is not totally sealed. Because it is not sealed and the leaks are not uniformly distributed you can have lots of flow(velocity) in some areas and very...

So you decided to write a book post of what he should do but just the other day you jumped on me about reverse feeding number one main. You told him to plug number one. Ok, then how is that bearing getting its oil. And what else do you think that plug at the front of the galley is doing. It cuts...

Wrong! The first goal is to stop feeding the drivers side lifters off of number 1 main. No matter if you do the tubing of the drivers side galley or the crossover. Both mods require a set screw at the front of the galley Or in the bearing saddle to stop the flow to the lifters. That set screw is...

D Done

Let me know if you got the email and if it’s readable. If anyone else would like at word document of the Sanborn oiling mods with pics and written instructions, just pm me your email.

I was going to post a drawing like that. It shows how ridiculous his understanding of hydraulics is. According to him, the oil will just sit in the galley going nowhere with 80psi pressure on both ends and not flow to the 4 leaks in the tube. He also denies that if you take away the front feed...

Read what I wrote. We are not in agreement. It has everything to do with bearing life.

I am not making your point. If his class rules required oil at the lifters, and you bushed lifter bores, you could restrict flow to your discretion with the bushing and leave the stocking method of oiling off #1 main as is. Sanborn claims this fails #1 main. Just as you spoke about those old...

And I am telling you that his notes specifically say it is done to reverse feed #1 main.i am pretty sure that I posted all his notes in the original oiling thread on this topic. My point to you is his vouching the crossover works just like Chrysler has, but it is a two part modification...

I went back and looked through my Sanborn notes. Two things I noticed. Yes indeed he used pushrod oiling. But he also had bushed lifter bores. So why run a crossover. You say it’s to feed the lifters. Sanborn says the crossover line was put in to reverse feed number 1 main bearing. I can repost...

Even if you don’t buy into the velocity thing, looking back at My Sanborn notes, he ran his own version of a crossover stating specifically that it was to prevent failure of number one main bearing which sends all it oil to the drivers side oil galley. So that is something.

The recommended mod in the stroker small block book completely abandons feeding the rockets from any bearing. I used brake lines Drilled directly into the main galley to feed the rockers. Kind of like how Indy heads oil. I installed the cam bearings out of position to completely block flow to...

I am not bitching about anything. Rapid Robert based on lengthy discussions with others has decided to do the crossover tube. It’s his choice. There is more than one way to skin a cat. I am just saying that bushing the bores is expensive and difficult to source that machining. The tube and set...

Yes but much more expensive. And not too many shops have capability to bush a small block Mopar. Ryan J did mine.

At this point in time I would not recommend it either. I have never done that mod myself for reasons already explained. I have done the tubing of the galley because it’s easier to do imho. But I find the oil mods in the stroker small block book even better. But reading what the crossover is...

If you have the book, then perhaps you need to read the entire explanation, and not just look at the picture. The proper implementation of the crossover is a two part mod. The passenger galley is plugged in front of the #1 feed hole. The pressurized oil that was sent to the drivers side now...

Did you used to post on this forum under a different name. I seem to recall a similar member arguing the same way you are.
