Such a great video! To bad the younger generation has no desire to learn these techniques,and be taught by the elders of engines on the performance side! Thank you Gerald. From East Tennessee, Ronnie
I think it's an experience thing to be honest. I feel like it has to do with interest in why a setup or component works better or worse/ fails that gets guys into engine building. A "What can we do to fix this" mindset. Younger guys just want to buy a setup that works so they can get out and use it. "I don't need to know engine tolerances I just need to pay someone who does" etc. The other side of that is in the time it would take them to learn with mixed results they can work OT and afford to get to it done right.
Thank you for another incredible video! It is interesting to learn that cam shafts can be bent during shipping to that degree as well as what you do test and adjust them. I continue to learn from each video. Thank you for proving that you can teach this old dog. Much love, prayers, and ear scratches for Ruby.🙏💜
I like the 'old school' techniques of using a V-block when a V-block does the job of a specialty tool that you don't have. Its always great to get back to the basics that drove automotive and aerospace industries for so long. A robot and a CMM aren't required, just someone who thinks on their feet, just like their father did and his father before that. Good common sense applied methodically gives great opportunity.
These days so few common sense things have been passed down that many today believe that aliens must have built things in the ancient world. We are a generation of unlimited knowledge at our fingertips, yet zero wisdom and very little common sense.
I for one have never seen an engine builder check and straighten a camshaft. Amazing attention to detail. You keep putting out the content and I'll keep watching.👍👍
I used to order my solid lifter cams for SBC circle track engines cut on Nascar Cup engine cores because of the higher Rockwell hardness numbers. Excellent video Gerald.
Another great video. Lots of tech about flat tappet camshafts I had never seen before. Nice to get some answers with the rate of camshaft failures you hear about.
Often wondered how many variables there are in camshafts, thanks for the insight sir you have a great way of explaining these processes you go through building an engine.💯👍👍
A great video explaining a problem a lot of folks don't run into! I rebuilt a Volvo inline four engine one time, back in the dark ages half a century ago, and ran into just such a problem. Volvo engines are built to pretty high standards and tolerances with this one having five main bearings, each one bigger than an American V8 crank bearing. I had pulled in five new cam bearings and then had the block line bored. I bought a new factory camshaft that was shipped in it's own protective tube, but it didn't seem to want to go into the block correctly. Experimentation showed a problem with the camshaft, so I took it to my trusted local machine shop. There they mounted the camshaft on the lathe and put the dial indicator on it. Turned out it was out of line on the center bearing by something like .015". The machinist had never seen such a thing and was surprised it hadn't broken rather than being bent. I took the camshaft back to the Volvo dealer who also checked and was surprised to find the same thing. Needless to say it was immediately traded for a brand new camshaft as quickly as one could get there. But I learned to always keep those possibilities in the back of my mind.
Great VIDEO!!!!!! man I have been learning so much watching your videos and I have been around/built/machined engines for my Late Model for over 30 years and I enjoy learning more thank you for sharing
The thing you're teaching someone like me who usually takes parts to a machine shop and has the work performed is I know see all the work that goes into it which makes the price seem alot more reasonable. I'm also learning what to look for in a great machine shop. I'm enjoy anything that sounds good and runs even better but my main love is Harleys. Thanks for the video Gerald
Thank you, Thank you! This information was also missing from my DYI engine builder kit. I had a cam go flat 15 min into the 20 min break in procedure. So disappointing I almost cried. I purchased the long block 383 stroker motor from a builder in Texas and followed his procedure exactly and it still wiped 4 lobes. I used the exact oil and zinc additive he recommended, but of course he insisted I had done something wrong. When I provided him all the receipts as proof he stopped taking my calls and blocked my phone. I should have known better as he was 6 weeks late in delivering the motor to start with. I was just looking for a simple motor swap and it turned into a very expensive nightmare. Mr. Brand, you are really getting the video production quality higher with every episode. I have learned more from you and Chief this winter than all my years of wrenching. Thank you, Sir.
Amazing information. Looks like I’m assembling this new little 383 myself. It’s been 36 years since I did one, and times are different. Really appreciate you helping normal guys like me.
tool steel flat tappet lifters?? whoa ....ps...im looking thru my harbor freight catalog but i cant find the rockwell hardness tester, im guessing thats a special order item
Ive been through a shop or 2 but i never seent the process of checkin hardness. Thanks for showin an ole boy! I guess that can be added while checkin clearances before final assembly. I put a big fat sharpie in my lathe and machine to lifter size to check my cam centers. Sharpie brand only cuz the fat cases got almost a quarter inch of meat you can cut down.
Most engine builders will not show folks some of this info. Hats off to you sir. I have no choice but to subscribe to your channel. I believe it will become huge. Thanks
That was really cool how you straighten a camshaft. I never thought about a cam being bent in shipping. Your wealth of knowledge is impressive. Thank you for posting another great video. Maybe in the future you could do a video of bearing clearance VS weight of oil. I am sure full blown race engines that use 50wt or higher have much bigger clearances than a street engine using 10w-40.
Another cool video. A helpful video could be one on setting rocker arms. One on degreeing a cam. Tuning a carb. Setting timing curves. Those are a few ideas off the top of my head that would be helpful to a lot of average Joes. Have a good day
I just switched to the tool steel cam and lifters. I ran the same Schuebeck lifters for 20 years. We will convert them to solids for use in a backup engine. Great video.
Thank you for sharing more of your great knowledge in this awesome video and including the cutie ❤Ruby❤. Really nice camshaft, checker and straightener.
Man I wish us import guys had guys like you/shops that would do videos on our kinda motors. Specifically for me lol 2jz motors 😅. Not saying we don't have good shops. Some of the best shops in the country are here in FL. But everyone is so unbelievable secretive about it. Especially in the race 1000 to 2000+hp import race engines . So little what you talk about would Correlate to my motor. But I love hearing about it. And if anything it's something to think about and ask questions down the road with dealing with a shop. Thanks for your videos and keep it up.
First video I've watched without BigCheif and like it just the same! Thanks for going through some tech and showing some steps. Really can appreciate (just some of) the many details that can get overlooked and how you implement the checks. All the best 👍
WOW love this i never knew this very interesting. I bought a cam once and on the way home i opend the box and it was broke. Glad we werent far from the parts store, so i could see how one could be bent.
Lots of information great video. My dad has told me since i was a child don't lay cams and cranks down they bend easy. Like the Midwest street cars plug.
Thank you for the interesting tech video. Surprise to know many people understand this tech video. I would like to understand this video like them !. Will keep on learning.👍
