For the 5% of us that understand every single thing Billy had to say, and enjoy being reminded of said knowledge, this was solid Gold. Please more technical stuff, it's ALWAYS appreciated by us 5%ers.
Your interviews of retired NASCAR drivers are very good. Keep them coming. Please consider interviews of drivers from other forms of racing, ie; drag racing, road racing, indy car, and others. This technical interview is excellent. We can't learn enough new information. We only discover what we didn't know. Thank You guys.
Props to you for getting a significant Portion of what I learned about camshaft design during a full ass bachelor's degree into about a 30 minute UA-cam video. Even if I already know the subject; I still love the tech videos!
@@picklefart yes .if you understand what hes saying. I don't know what's being charged today. It wasn't cheap then I can only imagine 2day. I took a class at the time was called Nascar technical Institute right there in Mooresville. Classes were called Nascar engines 1&2 . Probably my favorite classes. Went over cam design, head flow, jetting of carbs, effects of different timing, oil systems, differences in sparkplug position in head all kinds of stuff. Long story short i remember going over exactly what the man is talking about in the video
You were lucky to have one of the best instructors of reading a cam data sheet I have ever seen…..mic drop indeed. Thank you and all these guys for allowing you & Logan to come in and not only see but also take the time to explain or tell the stories. Thanks again, awesome work.
Talk nerdy to me daddy 🤣🤣 I actually like all these technical videos, I always learn something I didn't know from these kinds of vids. Keep up the awesome work.
To be able to spend some quality time with Billy Godbold is a treat that all of us should relish. He s a prime mover in this industry and is one of the people that you must listen to and learn from. Your video is very successful in having this quality time spent so give yourself a pat on the back for doing this for your viewers. We appreciate it. Good job.
Tech nerd heaven. I found out most of this info the hard way. This info was very hard to find in the early 80s. Ended up buying 5 sbc cams before figuring out that more noise don't always mean faster. Thanks for the refresher course. Always something to learn if you just pay attention.
Fantastic video! Billy is so very good at explaining cam tech. Lots of us have engines built using older tech & it’s great to learn how current cams have taken advantage of better components.
Man I love this rebuild story, for me I never understood how they tuned the sound but I was intrigued by all the information these men know their stuff ,excellent video. Thanks for the education.
This just made my (little) understanding of camshaft design go to another level. To see it graphically like that just makes it clear as day. That had to be the most technical yet simple explanation of anything I've ever experienced in my life. I truly appreciate this and the fact Billy took the time out to explain it the way he did. More so if Billy was a professor during my undergrad I'd have had a much easier time in some of my classes. Love learning.
Great interview and cam explanation. He turned Cam Magic into science and then explained it in plain language. I think I learned more about camshafts in this 20 minutes than the last 20 years. More like this is certainly appreciated.
I was able to literally spend over an hour with Billy years ago spec'ing a cam for a "magazine" project I was building and writing about that was one of those oddball combos. We literally went through similar discussions of "where in the intake and exhaust tracts the restriction would be" with the various intake/exhaust/head combos and selected lobes to make it all work. And it did! It was a great learning experience and I've used his info ever since. Folks would do well to pay attention.
Actually, it was great to have someone with such enduring/extensive knowledge, explain clearly to us simpletons the process of how a camshaft works. It also explains why the Coyote makes such good power with NO lope, from just 5 litres ! You and Tim from DragBoss Garage get the best guys in the industry on your channels....especially that Lake Speed fella😉 !!
Coming into this knowing next to nothing about cams, and having it explained that clearly and simply (and visually, that graph makes things click)...just freakin wow. I'll probably be watching this a few dozen more times in the near future.
This video just confirms my belief that internal combustion engines are lots of fun on many different levels. I have thumper cam in 454 with custom headers with very little muffled sound.
That was seriously profound information from a top tier person who loves sharing it. Fantastic chat. I loved the part where he mentioned two cams can have the same basic specs yet the valve movements travel through those measurements in such different ways that the power output can be dramatically different. I've heard that topic discussed before, but nowhere near as polished and thorough.
Me too! I literally have 100 videos in my watch later list and I will watch these first. Literally 99.9% of those videos are all Technical in nature and I don't have the time to completely devote my attention to it and that's why I haven't watched them. I'll make time for this gold
Absolutely! Not even a racing fan but love to hear solid information from the REAL experts. Especially when they love what they do and want to share their passion with the viewer.
To be honest, thats the first time I've ever had the dynamics of a cam design explained. I loved the "cause and effect" explanation of changes to create the optimal cam for an application. Now I know what to look for to make a thumpy cam. Thank you.
That was just freaking incredible. The physics and Calculus all made sense. Just never had cam science explained like that. Personally I dig this stuff. The science and math behind it all. I can go anywhere and watch burn outs. The more you tie each segment into the engine build the better. And keep Lake Jr in there. He is absolutely the best teacher in all this.
I could hang out with those guys for days, now I got more questions than I had before seeing this video. I can watch this stuff for hours and I`m surprised you`ve been given this kind of access to these shops and those people...very well done Mr. Stapleton.
This is one a person needs to watch more than once. The lumpy sound discussion was interesting to me, my old 396 had the Comp cam ( Wish I still had the build info ) But it made a very distinct huffing puffing sound at idle and under 25mph speed.
My racing career ended 25 years ago. I found this video so fascinating. Camshaft design back when I was racing was in the lower ranges on that chart. To see where design has come in 25 years is amazing. Like he said, in another 20 years it will advance again. Fantastic video.
I love this kind of technical information and Billy did a fantastic job explaining it. Back in the day, this type of info was very hard to come by, even in the automotive magazines. Very rarely is it explained to this level, even today. My wife may have tuned out a little bit during the video, but she knows this type of thing is "speaking my language."
I have been watching all of these videos as they have come out and I have learned so much that my head is on overload I always knew that the team's all did a ton of R&D but watching this series is just some of the coolest things I've ever seen done. I'm waiting like a kid on Christmas morning to see this motor go back into Lakes car and watch 6
Between this and engine masters can go hand in hand with each other. This was like a textbook type how it works and engine masters it the practical application side.
Mitchell, you killed it with this one! The tech explanation was amazing. This video should be a must watch if you want to know about how and why you engine makes or doesn’t make power, love it
I'm almost 50 and have been a mechanic pretty much my entire adult life. This type of video still gets my full attention every time. I mentored under an NHRA Pro Stock engine builder and this tech stuff is WAY more important than some of you might think (Thanks C.F.) Learn it, Live it, Love it folks. It will make you a better engine builder or whatever you might be trying to do. Oh and getting all this stuff right the FIRST time will DEFINITELY save you money and a lot headaches, for a fact. Y'all be safe out there. Thank You guys for taking the time and efforts to bringing folks this type of content!!
@@Stapleton42 No Biggie, Thank You for the content. Y'all are doing a hell of a job on this engine! Obviously, I'm not aware of how y'all got all this outstanding help. But the REALLY cool thing is that you're bringing us along for the ride. Not only is it simply great to watch. But if folks pay attention. There's a ton of very useful information, not to mention the history. Also what y'all are doing for Mr. Speed (I've always thought he has a kick-ass name!!) is just outstanding!! It shows your character, which is a good thing. Y'all be safe out there
I watched the whole thing, so nyah. I actually learned something fascinating about camshaft design and related equipment updates...all while blowing off being at work on time this morning. Concerning "which part of the video is the best?", this isn't really something you divvy up and pick a "best!" part of, it's a seamless instruction from beginning to end...and that's how you create interesting product.
This was one of the most amazing videos I have watched in a long time. I am pretty handy in the theoretical aspects of competition engine design and still learned a whole bunch.
Love the info about how the ramp rates work + understanding that whole "thumpr" cam series and how they sound so radical at idle, but really are pretty chill camshafts in use.
This video is priceless.... Pure gold from start to finish. I am building a similar engine based on a boss 302 block and thinking of using C3 heads. I'll be stroking it into the 350 range and using it in a vintage style trans am car. I'd like to be in the mid 600 hp range. I now know where my cam is going to come from. Can't wait to see the engine run on the dyno and see the car run. Thanks so much for giving us this level of tech info. Likes and subbed, not based on this video been following you for a while now.
That was awesome. Tell Billy thanks for taking time to be a part of your video and others. He is going to sell alot more cams. My friend Ken Shawver that ran Stock Eliminator and Super Stock always told me to talk to Billy.
I love the presentation of this. Listening to someone who knows what they are talking about. The depth of information is really nice. I'd enjoy more of this.
That was unreal, well done. Great to hear it all condensed like that. I’m used to boosted small displacement DOHC engines but the same principles apply.
All of these engine videos with Lake Jr. I have to watched 4 or 5 times. Each time I see something that I missed before. Can't wait to see the end results.
I know your channel was originated on trying to create essentially drag & drive vehicles. Just watched Drag Week 2022 and loved it. It was a car show with some drag racing interspersed. Have zero interest in NPK type of drama. Reality shows are anything but reality. I absolutely LOVE this type of content. I can go to 10000 other channels to "watch somebody do burnouts". I know you have likely lost subscribers over the new temporary direction. What some fail to see, or maybe care about, is this build and interviewing all these NASCAR legends will be a historical monument. I'm proud of you for doing it. I know it has it's boring moments for you & some of your subs. But us older folk, that watched these people enter/go thru the sport, appreciate the effort.
What I find fascinating, what he’s he’s saying this is happening at a fraction of a second, I followed 100% what he’s saying, but it’s how he’s passing on his knowledge. Awesome thank you 🇬🇧Paul
THUMPER THUMPER THUMPER - We need MORE videos like this explaining the finer details of exactly why they spend thousands of hours designing the right cam for your application. Sound is everything when it comes to "hearing what the other guy has", if it sounds wild, the first thing you think about is "how much power does that thing make?" How many of the younger generation would understand "I have got a 3/4 race cam." Do not stop making this kind of videos. Make more of them.
This was my sunday morning coffee video and I was super excited! I went to an automotive tech school for 3 years in the late 2000s and its really cool to see the progression of tech to make power. We get to live through the second muscle car era!
The science of a camshaft is so cool and a true art form. The past few years some of the content on cam tech just blows away some of the stuff I learned in the 80's and 90's in the magazines. Granted the tech is always moving forward. Good work! I am trying to spread the channel!
I am an engineer so all of the "tech nerd" stuff is very interesting to me. I love to find out how things work. This was more information than I ever knew existed for cams.
Im loving these videos, as an engine builder it’s really cool to see how Passionate Billy Goldbold is about Camshaft design even after all these years, im the same way about everything in engine building and design, it’s really cool that you have the for site to go talk to these geniuses of the automotive aftermarket! They will be timeless!
Buddy, your videos are so cool. Im 35 years old and I've had so much interest in this stuff for years and it's really hard to find this level of detail about these engines etc, it's nice seeing the younger generation have so much interest in this stuff. Keep doing what your doing!
That was deep, definitely had to watch a few parts a few times I’m a little surprised at the lift and rpm range from 20 years ago compared to what’s available today. The sound part of that graph is interesting also. Good stuff again 👍
Absolutely awesome, as a dirt track racer. Alot of the times when discussing cam profiles with our supplier(lunati). These terms get lost in translation. Thank you so much for posting. KEep these highly technical videos coming!
Thank you for showing this! My "ahh ha" moment was when he was talking about the difference between the two cams with the same printed specs but how they changed the opening and closing rates and how much it affected the actual overall horsepower. For instance I have a Magnum 280 in my 71 Camaro and I've often thought about changing over to the XE 274 which has very similar printed specs accept it's a split pattern cam, but it was never clear to me what would justify the cost. Now I'm actually convinced because I know if there's one thing the XE cams are known for it's the accelerated ramp angle. That Magnum 280 is 70s technology 😂
I just listened to the old Power and Speed podcast (Highly recommended tons of amazing tech info) with Billy and this is a great addition with visualization.
I LOVE the tech stuff. It showed cams are grinded to the spec engine and it’s application!! He did a AWESOME job explaining it. Love the tech stuff, I’m in Aerospace so more the better and you-gf questions were GREAT!!!
Still behind but catching up. This was a wonderful video. For me, if there was ever a weak point into engine building is the understanding of cam designs. This video shine a ton of light! Really loving this stuff and can't get enough of it! Thanks so much Stapleton for putting in the work and making the effort to show us grassroot folks about how this stuff is done. Racing history, technical stuff, everything! You put in the time and I'll watch it all and absorb it like a sponge. Plus I get an education on top of it all! What's not to love about this channel?! It's got it all! Oh btw I'm definately interested in that factory tour video...
Most interesting thing in the video is the physics lesson on acceleration of the air mass vs piston speed and the relationship to the intake valve opening for the purposes of filling the cylinder. If you get it, you get it, if you don’t, pay a pro to package your engine combination for you and enjoy their hard work responsibly.
Love this video! Outstanding information delivered by a very good instructor. i could listen to him explain engine static and dynamic properties all day long. Thank you both for putting in the work and delivering such quality content!
Almost 30 years building engines in my cars and multiple trips to North Carolina to engine builders… I got more information and learned more in this one video. Thank you!
Absolutely love these tech-type videos, am familiar with a lot of tech stuff myself so it's all good! So glad that you & Logan were able to go behind the scenes and do these videos for us all, always much appreciated. Totally there with you guys till the last second of each video! Thank you so much!😎👍👍👍
I think this video is fascinating! The amount of knowledge that can be learned from these Nascar engineers is amazing. I love hearing how the technology has changed
Good lord, the amount of juicy, flavor filled cam info on this video! This is really valuable info for people that are trying to select a cam for a project. In my experience, get in touch with Comp and talk to them about your set up and goals They will hook you up!
Love listening to masters explain their craft. Some of that was basic understanding of cams but some of the detail was food for thought. How about a video from an engine shop showing the entire system how the variables change VE, BMEP and and how it's all tuned to specific race applications. It would be cool but you probably won't find a shop willing to let you in asking for that kind of detail.
Biggest take away is if you're actually building an engine for purpose you need to get in touch with a cam engineer like Billy with all the specs of your engine. Picking from a catalogue or phoning the tech line of a big company is a shot in the dark. Thanks for posting and showing what little knowledge I have on the subject. Cheers!
How is this channel not bigger? You're speaking privately with some very smart guys from the industry. This is gold.
I don’t know man. It’ll get there with time
@@Stapleton42 it will for sure this is great!
As he said 95% of people want burnouts and funny cats! (wait I like funny cats)
I could probably drive this guy crazy with questions, the more you know,the more you understand how and why,thanks again for all you guys do
Amen!!!
For the 5% of us that understand every single thing Billy had to say, and enjoy being reminded of said knowledge, this was solid Gold.

I got to work with Billy for a couple years. It is such a pleasure having him explain things the way he does.
Attention to detail at it's best 👌
That's an indicator of someone that really does know what he's talking about.
Probably the most intelligent explanation of cam design I've ever seen
And that's just the high level overview haha Billy has the ability to break your brain when he wants to

So cool seeing Lake Speed's engine be restored. 🏁❤️
We miss Lake 😢
All these tech videos on Speed’s engine and old racer stories definitely earned a follow.
Thanks man welcome to the team
The cam slowing down and speeding up because of the spring is a super interesting concept that I never thought about but makes perfect sence
I love how much technology has allowed the cam makers to really get aggressive with the cams.
Honestly, I enjoy the techy part because it helps me understand what's about to happen when I stomp the loud pedal
That was just freaking incredible. The physics and Calculus all made sense. Just never had cam science explained like that. Personally I dig this stuff. The science and math behind it all.

I was right there listening to every detail, learning all I can
Best valve train dynamics and cam geometry I have ever heard! Always have heard good things about Comp Cam and now I know why...!
It’s always good to get more knowledge from a professional to help you get the knowledge that you need to know
Man this video was badass! Keep this kinda stuff coming!
All of it was interesting, very good knowledge through out this video
Thank you Hank!
This dude knows his stuff. Great watching and I will watch again. Keep it coming.Well done.
This was my sunday morning coffee video and I was super excited! I went to an automotive tech school for 3 years in the late 2000s and its really cool to see the progression of tech to make power. We get to live through the second muscle car era!
That is awesome!
Chevrolet NASCAR Engine With 355 Cubic Inch V8 From The 70s 80s And Early 90s Small Block With Camshaft Thanks For Uploading
The science of a camshaft is so cool and a true art form. The past few years some of the content on cam tech just blows away some of the stuff I learned in the 80's and 90's in the magazines. Granted the tech is always moving forward. Good work! I am trying to spread the channel!
Thanks man we really appreciate the help!!
I am an engineer so all of the "tech nerd" stuff is very interesting to me. I love to find out how things work. This was more information than I ever knew existed for cams.
It's exciting isn't it?
Im loving these videos, as an engine builder it’s really cool to see how Passionate Billy Goldbold is about Camshaft design even after all these years, im the same way about everything in engine building and design, it’s really cool that you have the for site to go talk to these geniuses of the automotive aftermarket! They will be timeless!
thank you Derek!
Buddy, your videos are so cool. Im 35 years old and I've had so much interest in this stuff for years and it's really hard to find this level of detail about these engines etc, it's nice seeing the younger generation have so much interest in this stuff. Keep doing what your doing!
Thanks man!!
Keep the Nascar history episodes coming. And all the tech and mechanical info is always interesting. 👍🏁
We will! Thanks Brian!
That was deep, definitely had to watch a few parts a few times I’m a little surprised at the lift and rpm range from 20 years ago compared to what’s available today. The sound part of that graph is interesting also. Good stuff again 👍
Always wondered why nascar race engines had that quick cam sound. This kind of graph and visualization was great
You're killing it with this content dude. All this stuff is just so fascinating to me.
Thank you Donnie!
This is one of the better videos you’ve done in my opinion.
Billy definitely knows his stuff.
Cylinder head tech is my main interest…
Thanks man! We will have some neat cylinder head videos coming
Absolutely awesome, as a dirt track racer. Alot of the times when discussing cam profiles with our supplier(lunati). These terms get lost in translation. Thank you so much for posting. KEep these highly technical videos coming!
Thank you for showing this!
My "ahh ha" moment was when he was talking about the difference between the two cams with the same printed specs but how they changed the opening and closing rates and how much it affected the actual overall horsepower. For instance I have a Magnum 280 in my 71 Camaro and I've often thought about changing over to the XE 274 which has very similar printed specs accept it's a split pattern cam, but it was never clear to me what would justify the cost. Now I'm actually convinced because I know if there's one thing the XE cams are known for it's the accelerated ramp angle. That Magnum 280 is 70s technology 😂
Your impression of "burnout vroom vroom" people was spot on. Give me cam specs anyday over burnouts.
I just listened to the old Power and Speed podcast (Highly recommended tons of amazing tech info) with Billy and this is a great addition with visualization.
Your thumper question was a great question! The technical explanation he gave with the chart visual was awesome.
Glad it was helpful! Billy is a rare genius that can explain genius concepts to regular guys like us 😂
I LOVE the tech stuff. It showed cams are grinded to the spec engine and it’s application!! He did a AWESOME job explaining it. Love the tech stuff, I’m in Aerospace so more the better and you-gf questions were GREAT!!!
Thank you Travis!
I actually enjoyed this whole video, I understand cams but hearing it from a professional is awesome.
Still behind but catching up. This was a wonderful video. For me, if there was ever a weak point into engine building is the understanding of cam designs. This video shine a ton of light! Really loving this stuff and can't get enough of it! Thanks so much Stapleton for putting in the work and making the effort to show us grassroot folks about how this stuff is done. Racing history, technical stuff, everything! You put in the time and I'll watch it all and absorb it like a sponge. Plus I get an education on top of it all! What's not to love about this channel?! It's got it all!
Oh btw I'm definately interested in that factory tour video...
Thanks man!!
Most interesting thing in the video is the physics lesson on acceleration of the air mass vs piston speed and the relationship to the intake valve opening for the purposes of filling the cylinder. If you get it, you get it, if you don’t, pay a pro to package your engine combination for you and enjoy their hard work responsibly.
cam specs are like black magic to most people, amazing
Love this video! Outstanding information delivered by a very good instructor. i could listen to him explain engine static and dynamic properties all day long. Thank you both for putting in the work and delivering such quality content!
Almost 30 years building engines in my cars and multiple trips to North Carolina to engine builders… I got more information and learned more in this one video. Thank you!
Billy godbolds a legend I follow an engine building page he’s on and man he absolutely is an engine genius
for me the coolest thing is showing the reason on all of the engine parts on why and how the engines today make more power.
Absolutely love these tech-type videos, am familiar with a lot of tech stuff myself so it's all good! So glad that you & Logan were able to go behind the scenes and do these videos for us all, always much appreciated. Totally there with you guys till the last second of each video! Thank you so much!😎👍👍👍
Thanks mark!
I think this video is fascinating! The amount of knowledge that can be learned from these Nascar engineers is amazing.
I love hearing how the technology has changed
Thanks John!!
Its wild they where limited by components such as the valve springs at the time.
I like how excited dude got about explaining how the sound works
Same!!
That was amazing to learn for sure it makes understanding how a cam actually work more than just the numbers you see. It makes it make sense.
Good lord, the amount of juicy, flavor filled cam info on this video! This is really valuable info for people that are trying to select a cam for a project. In my experience, get in touch with Comp and talk to them about your set up and goals They will hook you up!
Thanks for broadening my knowledge on camshafts. I found it very interesting and useful.
It would be interesting to see them explain a performance camshaft for turbocharged engines.
The sound explanation was mind-blowing!
Dude !!... 1 on 1 with Billy Godbold !! I could listen to an entire series like this and not get bored. Awesome job.🍻
These are the best explanations I've ever heard. Soo simply put.
Love listening to masters explain their craft. Some of that was basic understanding of cams but some of the detail was food for thought. How about a video from an engine shop showing the entire system how the variables change VE, BMEP and and how it's all tuned to specific race applications. It would be cool but you probably won't find a shop willing to let you in asking for that kind of detail.
Biggest take away is if you're actually building an engine for purpose you need to get in touch with a cam engineer like Billy with all the specs of your engine. Picking from a catalogue or phoning the tech line of a big company is a shot in the dark. Thanks for posting and showing what little knowledge I have on the subject. Cheers!
The technical stuff is really, really good!!!!! Understanding how this stuff works explains so much.
We’re glad you learned from it!
