Back in the 60s when the 426 max wedge was one of the tires of the strip out there I read an article where Chrysler would take the block after they took it out of the core box before they did any machine work naturally, they cleaned it up real nice and clean. Got all the sand out of it of course and everything and then they would put it in the oven And heat it up to about 1200° real slowly bring it up and let it cook away for about several hours and then slowly cool it off that made the block the Rockwell numbers equal top the bottom side side and stuff like that I wonder if that would still be a good thing to do with my 5.9 Cummins for my Dodge pick up
sunnen doesnt have a silicon carbide 100 grit shown for the an112 hones so i bought some 80 grit keystones and will plateau the after with 400 grit keystones with wipers, i have the sunnen pht731brushes but found they are only 320 so i guess the 400 will give me a better rpk. i recently tore down my previouys rebuild the i did with 180 followed by the brushes and it seems like my residual cross hatch or rvk was mostly gone .. so after your very informative webinar -thank you by the way ... i am droping to the 80 and going straight to the 400s unfortunately i dont have a profilometer and no one i know seems to have one either i wll be going by seat of the pants methods.. what do you think ,Thanks..

EXCELLENT Material coverd here! I had a heated discussion with a so called "Expert" on plateu honing proceedures...The guy claimed "Ball Hones are JUNK!" nice to know that I'm not the only one who has had some good results with Brush Research products in my builds. I can't afford a new diamond hone at the shop volume we are at...Our old CV616 still pays the bills. Yes I would love to have the best but, I do the best with what I have.
My Hemi has tool steel rings and cylinders its built like a top flue bottom end crank manso aluminum rods Arias pistons. Some cool stuff he's talking about.
I know this is old, but I just found a different technology that I may be using on my pistons call WPC. It may not be new to you, but will the hardness of the WPC pull off the Nikasil? I hear it works really well with DLC coatings.
Believe me...Many USA shops cannot afford a modern High HP diamond hone, we shops without the expensive technology use attention to detail and good cleaning proceedures to make good power and longevity. Proper cylinder cleaning after honing is a subject that should be covered....WOW! I hadn't listend all the way through....Keith did a great job @ the end of the video describing a proper cleaning process...I've known too many shops that just put a honed block into a high pressure jet washer...run it through a cycle then spray down the cyliders with WD40 and call the cleaning process finished....Not good enough for my builds.
Having a issue sealing Chevy 6.5 diesels after .040 over. Ran it extrem blow-by. Teardown of engine rehone and different rings same results. What kind of oil would you recommend ? For Breakin.
There have been reported issues of bore distortion in those engines, a re-bore would further exasperate the problem and if the bore isn't consistently round, no ring is going to seal well. If you're running higher cylinder pressures (higher boost) it will just get worse. You may need to look at getting it sleeved and/or gas porting the rings.
Very informative video, especially for the layperson, like me, who normally has to rely on the machist to know what they're doing. I was wondering about your thoughts on bore/hone plates and circulating hot water through the block? With some of these very smooth and/or hard bores there will be little wearing to account for bore distortion with temprature, so it will rely on the ring flexing to the bore shape?
Thanks for the feedback and the question. Torque plates increase the assembled bore cylindricity. Simulating the clamping loads makes a huge difference. Hot honing is also an advantage that is employed on many endurance racing engines.
@@TotalSeal I had a thought, after posting that, that the modern trend for 'open' decks may be partially driven by isolating the cylinders from the stress, and deformation, around the threaded head holes. It also exposes a little more of the cylinders to the coolant, which may be expected to help stabilise thermal variations and distortion.
@@gordowg1wg145 That is very logical. We don't design engine blocks, so we don't have any engineering data to validate that theory. However, those are good points.
@@TotalSeal even my machinest I work for here and there has not heard of the gasported rings yet when I asked him today about it and he buys rings everyday and I have not purchased a set for anything I been doing cause I have nothing going on!
I guess you machinist needs to check out our Hidden Horsepower podcast 😀 The gas ported rings are new, so he probably would not have heard about them from a parts warehouse.

Great information

Thanks for the comment. Keith is the man!
Could you guys please speak more on the plasma spray cylinders in the ford modular engine.
We will have a video coming out this year on that topic. Also the Porsche Club of America has a great video on this topic as well.
@@TotalSeal Awesome thank you.

We know about WPC, it will not affect Nikasil.
I appreciate these videos 💯, too bad i cannot afford that tool nor do any machines shops here use them 😅 third world issues !
Thanks for the feedback!
I'm at third world too... Really appreciate this videos

Is there any way to get a smoth finish with a diamond 280 grit ? Manley pistons are asking for a 280 grit finish but that's too rough?
You can plateau over the 280 with a 400 grit for a few strokes. Watch this video: ua-cam.com/video/IUJDrHR1qsc/v-deo.htmlsi=1bumgX-bjYCcCyyk
Is a higher PSI compression test better than a lower psi? Can you have too much psi?
Higher cranking compression is better than lower cranking compression
1:00:32 handhone is mentioned, what options are available?
The dingleball hone is fine for deglazing a cylinder, but hand hones are not recommended for high performance applications.
Having a issue sealing Chevy 6.5 diesels after .040 over. Ran it extrem blow-by. Teardown of engine rehone and different rings same results. What kind of oil would you recommend ? For Breakin.
Driven offers a diesel break-in oil. That would be worth trying, but also check the surface finish of the bores.
There have been reported issues of bore distortion in those engines, a re-bore would further exasperate the problem and if the bore isn't consistently round, no ring is going to seal well.
If you're running higher cylinder pressures (higher boost) it will just get worse.

not one comment when this info should be as popular as covid-19 chewing gum sold today.
It is critical information. Thanks for the comment!
