That's the exact same reason I'm entering. Data. Data helps us all. Excellent point about the guys who do nothing but cams, it's an educated/experienced guess based on previous engine data. You don't know what you have until it's compared against something else. Good luck to you sir!
There's some real intelligent folks entering 👌. David Vizard, You ext. I like what Eric said. I soon as it started to float the valves it's done ✔️ 👍 Can't wait to see the date. God Bless Everyone and stay safe 🙏. Trust in our Lord and Savior Christ Jesus
One accurate dyno test is worth more than an internet full of opinions. Empirical data is what it's all about. Good luck Daniel, I was really glad when I heard you entered and the bonus was you had 2 cams.
So far everyone I have seen post about entering has done so with complete humility. I love to see folks that somewhat compete with each other join together for something fun, that will also drive data to help us all. Good for all of you.
I watch your channel, Erics, Lykinmotorsports & a couple others. And i can say that i am always greatly appreciated and look forward to all you guys knowledge. So keep up the fantastic work. 👍 Watching from 'Down Under' OZ 🇦🇺
Sounds like this could easily be a reoccurring event a few times a year with different engines. My love is the M50 straight 6's so no magic numbers for me but I am learning a ton through these discussion and I expect I will learn a ton more when the numbers and results get discussed.
Thank you! For your opinions, knowledge, etc. I've seen so many people get out of this hobby because of bad experiences that it's refreshing to see those who truly try and add to the knowledge base. The more people that decide to get into this hobby, the more it benefits everyone!!! Best of luck to ya!
Internet experts are the best entertainment. You can pretty easily tell who has never put their hands on something. Fact is, there is no perfect template. All you can do is get close and start experimenting. Every engine base and application has far too many variables to make a repeatable result every time. The guy who who can say " I've seen this before" always has the best first shot. After that, it's test and measure.

You hit it on the head! There’s a big difference between a “Dyno” cam and a real world works in a chassis cam. The 11.45-1 SCR is a limitation especially with the large port volume and high numbers in the heads. I was able to come up with a cam: 662 hp @6500 594 TQ @5000 Avg hp 579 Avg TQ 555 Eric says the dyno will adjust to sea level/temp/humidity. The DCR with the cam I specs so far is so low it would run on pump gas. 😳👍
Good to see ya'll, I hope that in your absence it means you guys are working hard doing right by your customers... That's what'll make me drive to you just to fix an engine..... Right !! peace & GB ALL
I need to get unlazy and send you a cam to fix. I spoke to you about it months ago, life happens. I keep checking your website for Gaterman lifters too, they've been out of stock.
This is all about subs and views. Everything else has already been done . Cams and head porting match has already been matched . If not , we wouldn’t have drag races with 7-8 second 1/4 mile times.
Yup, as I've said MANY times, it's all learning or revision - the guy, or gal, that thinks they know everything already, is going to be an also-ran. Sorry, but I stopped subscribing to channels a long time ago, because I realised I had way too many I wasn't keeping up with - it's mostly 4 banger twin cam's now. That said, there are a LOT of those guys, especially higher boost, that need to learn about valve control and spring seat force/pressure. I do make a point of giving likes, though - don't know what difference that makes.
Scavenging is the anomoly to control. This is complicated to compute. Exhaust dimensions are only correct for specific volumetric flow. A cam for open headers is not the same for the engine in a street car with exhaust tailpipes. Application?
I 100% agree! That is why I sent a cam in as well. I think this is turning into something pretty cool. If, for some reason, I were to win something in the contest (which is not really even my goal), I will just donate it back. I think we are ALL going to be better off, from a knowledge standpoint, after this thing is finished.
@@dannydurham5716 I gave $20 also. Hope it helps. I know very little about engines but I love tests like this. Sure it’s a competition but the outcome will be great for everyone regardless of where they finish. I hope there is a follow up to this competition. One thing I am curious about is I wonder if a lower placing cam could actually do better on the track in an identical car?
I think your channel, Eric W channel, Richard Holdner and Steve Morris’ channel are the most informative engine channels on YT. The amount of knowledge shared is tremendous. Shade tree mechanics like me can learn an awful lot.
"If I win, I will donate the winnings back to you" Sounds like judge tampering to me😂😂😂 All jokes aside, I’m really looking forward to numbers and data, thank you.
Yep. I don’t expect one cam to just run off with HP or Tq. I’m just excited to see the numbers. I had no idea how interconnected all these channels are. Glad summit is in also. Makes me want to support Summit. Good luck
A while back Richard Holdener did some hydraulic LS cam testing and found more power with longer pushrods beyond what the rocker arm geometry indicated was correct. I asked him why...and postulated that the lifters were slightly pumping up thereby making the cams act larger than they actually were. He responded that the lifters weren't pumping up but didn't offer an explanation of why they made more power...which told me he didn't really understand why. Hopefully this cam testing will shed some light on the subject and thank you for participating!
There is less oil on the bottom side of the plunger and higher plunger return spring/check valve pressure. I proved the longer pushrod theory about 15 years ago by complete accident. Not only do they make more power, but they are also significantly quieter. Quieter is what I was looking for. Extra HP was a nice surprise.
I'm no expert. However, as the engine increases in RPM, the oil starts to airate , and the air in the lifter can compress slightly, thus reducing lift and duration . David Vizard talks about adjusting hydraulic lifters at the bottom of its travel for this reason, not at the top of its travel like most of us would do
Is anyone certain that a lifter stays 100% full and rock solid during engine operation? If it collapses at all, you’re losing lift and duration. Checking lengths with the current methods only tell you of the result assuming 100% solid lifter operation. The longer push rod may become the correct length and account for the lifter partially collapsing at rpm.
view looks more like NASA versus a machine shop! :) Fascinating to watch, when I built my 351 4V in the 80s I could only catalog shop and picked up a Crane fireball and a set of lifters and some new triple valve springs, my only complaint is it liked to pick up traffic violations :)
I paid Eric a little cash to give me some specs for a little SBC I’m putting together based on the overall car. It will not be “perfect”, but I’d be willing to bet it’s better than what I would have picked. It’s much smaller lift than I expected but he explained why in 3 sentences and I get it. I was happy to toss a little money his way to support his business
Hey mate, I love your videos, you're super professional and have great ethics. I wish I knew a fraction of what you know, thanks for educating us. Lots of love from Australia.
May I suggest a follow up video that explains the theory behind your cam grinds? The cam test will be interesting, and I suspect the majority of the cams will be close in power-the reasonable cams and not a wild, no hold barred, contest cam . Good luck and thank you!
In the past NASCAR teams building their own engine did what was stated. They would have the cam grinder grind 3-5 that were very chose and if others found out what another team was using they didn’t really know.
Im not so sure the big cam companys are doing the best job there.there job is to sell you a cam and could care less if the public gets the best cam for there combination. it's up to the consumer to do there investigation with the information he or she can gather. best of luck with the cam challenge.
This is a perfect response. I don't run hydraulic. I just run solid roller and im a sbc bbc guy, not an LS guy but I support all racing stuff. When he very first made a video on this cam challenge, I put your name in the comment section within 1 hour of the video. I said it would be nice to see you enter since you do your own custom ground cams and on youtube. Good luck!
I'm excited for the results. Richard Holdener has lots of test for LS cams but I want to see some other grinds than the widely available ones. I still owe you for showing me how to save my engine block. I still will do it after I finish getting everything done, engine was put in yesterday just have to finish buttoning things up. I'm slow but I will follow through because if I didn't see your video no way I would of been able to fix a warped main by myself while staying within the factory block specifications.
about your chanel when i watch you on my i phonr i have to watch ads,or part ads as i can hit skip,i figure if they are putting ads on your videos,and they are not relevant to your topic, them youtube shitheads should be paying you more than they are, as i am sure the ads are paying to interrupt your posts
The nice thing about this cam challenge is the cam is the ONLY variable changed in the engine. Now, I doubt Eric is going to spend the time to optimize each cam to this engine, but at least you'll have the data for that specific package. Then you can make 'educated guesses' from there, when your customer wants slightly different components that deviate from this setup.
Never forget that the off the shelf cam companies are giving generalized guesses and the customer gets some gains, maybe not THE BEST, but enough to be satisfied.
@powellmachineinc3179 That's great. I expect the top 5 to be within about 5% of each other. Would be shocked if there was a run away that's ground against the norm. But then everyone would be scratchin their head!
This is going to be VERY interesting… And I’ve liked and subscribed to not only your channel, but Eric’s, Vizard’s, and a few others’ channels. I appreciate your efforts and sharing of the information- thank you!👍🏻
This is an exciting challenge! Im also excited to run the custom cam you guys ground in my turbo LS 300zx! Your humility is priceless too, the chest pounding gets really annoying
I believe you're 100% correct. This contest will probably only help all parties involved. I've been sub'd to you for a while now as I enjoy the info and you're laid back style. You're subscriber count has probably already picked up. It'll likely help get more work to your door too. Good luck!
@powellmachineinc3179 I wouldn't either, that's just bullshit..I think your a very straightforward guy ,you don't deserve that at all..have great day 👍!
Thanks for the update and participation ! I'm VERY excited for the data as well, to the point that I'm not buying a cam for my new 408 build until this is over ! I feel you and Eric are 2 of the most honest guys on YT so i have 0 concerns about this test. I've reached out to a few guy's that are "big" in the LS world and they said.... "sounds interesting, we're in, check my YT page" etc.... 1 even said don't email me again ! Lol I was just trying to get the word out about the contest and possibly get more subs for Eric. It'll definitely be interesting !
Good luck on the testing Daniel. I think it is nice that you could send two cams. I am excited to see how all the dyno/camshaft tests go. Thanks for the update.👍🇺🇸👍
To be fair it does cost us money to have devices to watch and money to access the internet as well and electricity etc if using pc. And believe it or not our time also has value we’re not just losers laying around all day…well sometimes and some of us probably are. Not me though 😂
just to let you know I appreciate everything you put into these videos... I actually tell my friends, " I can't believe this info is free" .. I might not have a lot of money to donate, but I do try to spend what I can at the various channels web sites if possible... The more cross channel interaction seems to be the way to go... between Vizard, steve morris , Holdener, cleetus, etc....... there are ways to boost each others channels and even promote certain products... This is a time in America we will look back on because it won't last to long... keep up the great work and great videos....
Your videos are always instructive and great to watch. What makes them even more enjoyable. Is that you are a straight forward guy. A person a man would trust to do business with. Thank you for taking the time to post your videos and share your knowledge. Wishing you and your family the very best.
Hi, I also follow Eric. I agree completely. I think this is an excellent way to accumulate knowledge. I was a little surprised he made the max lift as high as he did. Does he consider that the max lift for a street able LS cam? Or is .668? ( is that his max lift?) at the edge of HIS valve train reliability at this max lift? My big concern? Most of these internet experts- the ones who will scream the loudest- about things they know nothing about- will do just that when cam "C" makes 3 hp less than cam "J" As you know, there are so many variables as to why 1 cam makes omg! 5 more hp at 7k than another cam. I am glad you entered. I hope you and the others who entered all learn something from this. Good luck.
This is similar to the testing for EMC (Engine Masters Challenge) that was a great learning experience. I really miss the competition and the great folks that brought all their different ideas and engines to the challenge. It was a chance to compare how well we compared with some of the best. Hopefully you will meet your expectations. Good luck.
There is way more ego in the automotive world than ability. It doesn’t bother me if they are in proportion. From what I have gathered I think you have some stiff competition with Vizard. If you win it’ll make him rethink things. GOOD LUCK!!
Hey Daniel, Tim here, yea, its a tuff challenge, as he aint gonna degree ANY of them!!.....the parameters dictate, that u shud know how much advance or retard to grind in, puttin it straight up, as well as other parameters, which i think will give GREAT DATA for ALL involved, and i think thats the BEST way to administer a challenge like this.....its fair for everybody, and we'll get GREAT DATA!!!!....i wanna see ur more aggressive dude.....just cuz i like aggressive ramp profiles.....knowing my bullet is properly prepared for it.....CANT WAIT!!!...
I had to go back to his challenge. The 0.660" lift limit is instructive: port seems to back up after 0.700" lift. It may be that less is more in avoiding subsonic choke: could 0.648" be a good number? I wonder because velocity map seemed a bit wide [floor vs roof] maybe? Guessing at short turn behavior is best done by porters with a bit of dyno experience, and I am a hobbyist lacking dyno time [with an assortment of cams]. Anyway, all fun on my end: I'll be wrong and somebody will win - no time or cash to throw at anything right now.
You are wrong about it not costing anything for us to watch. Our time is valuable just as much as yours. This isn't a insult but I watch both channels and its like watching paint dry...
That's the exact same reason I'm entering. Data. Data helps us all. Excellent point about the guys who do nothing but cams, it's an educated/experienced guess based on previous engine data. You don't know what you have until it's compared against something else. Good luck to you sir!

Yes, that's how it works, we get paid by how many adds u watch, but it's very little
The nice thing about this cam challenge is the cam is the ONLY variable changed in the engine. Now, I doubt Eric is going to spend the time to optimize each cam to this engine, but at least you'll have the data for that specific package. Then you can make 'educated guesses' from there, when your customer wants slightly different components that deviate from this setup.
Absolutely agree
Never forget that the off the shelf cam companies are giving generalized guesses and the customer gets some gains, maybe not THE BEST, but enough to be satisfied.
My main question would be..
Do all participants get everyone's specs and placing after it's over? To me, that would make it very valuable.
Yes, that's how it's laid out
@powellmachineinc3179 That's great. I expect the top 5 to be within about 5% of each other. Would be shocked if there was a run away that's ground against the norm.
But then everyone would be scratchin their head!
This is going to be VERY interesting…
And I’ve liked and subscribed to not only your channel, but Eric’s, Vizard’s, and a few others’ channels.
I appreciate your efforts and sharing of the information- thank you!👍🏻
Absolutely, glad to do it
This is an exciting challenge! Im also excited to run the custom cam you guys ground in my turbo LS 300zx! Your humility is priceless too, the chest pounding gets really annoying
Bad ass!
Time will tell
I believe you're 100% correct. This contest will probably only help all parties involved. I've been sub'd to you for a while now as I enjoy the info and you're laid back style. You're subscriber count has probably already picked up. It'll likely help get more work to your door too. Good luck!
Right on
Don't let the haters get to you brother!
Definitely, but not going to tolerate folks lying on me
@powellmachineinc3179 I wouldn't either, that's just bullshit..I think your a very straightforward guy ,you don't deserve that at all..have great day 👍!
Thanks for the update and participation !
I'm VERY excited for the data as well, to the point that I'm not buying a cam for my new 408 build until this is over !
I feel you and Eric are 2 of the most honest guys on YT so i have 0 concerns about this test.
I've reached out to a few guy's that are "big" in the LS world and they said.... "sounds interesting, we're in, check my YT page" etc....
1 even said don't email me again ! Lol
I was just trying to get the word out about the contest and possibly get more subs for Eric.
It'll definitely be interesting !
Absolutely 💯
Good Luck to everyone!
Tyvm 😊 🙏
Good luck on the testing Daniel.
I think it is nice that you could send two cams.
I am excited to see how all the dyno/camshaft tests go.
Thanks for the update.👍🇺🇸👍
Absolutely, I can't wait
Pulling for you man....
Tyvm
You're a good competitor good sportsmanship something we forgot about sometimes
To be fair it does cost us money to have devices to watch and money to access the internet as well and electricity etc if using pc. And believe it or not our time also has value we’re not just losers laying around all day…well sometimes and some of us probably are. Not me though 😂
just to let you know I appreciate everything you put into these videos... I actually tell my friends, " I can't believe this info is free" .. I might not have a lot of money to donate, but I do try to spend what I can at the various channels web sites if possible... The more cross channel interaction seems to be the way to go... between Vizard, steve morris , Holdener, cleetus, etc....... there are ways to boost each others channels and even promote certain products...
This is a time in America we will look back on because it won't last to long... keep up the great work and great videos....
Tyvm!!
Glad to see you in the test! Looking forward to getting a ls cam ground for our 67 nova here in a couple months
Awesome 👌
Your videos are always instructive and great to watch. What makes them even more enjoyable. Is that you are a straight forward guy. A person a man would trust to do business with. Thank you for taking the time to post your videos and share your knowledge. Wishing you and your family the very best.
Ty, we really appreciate that
I'm looking forward to the test and the knowledge learned.
You and me both!
Hi, I also follow Eric. I agree completely. I think this is an excellent way to accumulate knowledge. I was a little surprised he made the max lift as high as he did. Does he consider that the max lift for a street able LS cam? Or is .668? ( is that his max lift?) at the edge of HIS valve train reliability at this max lift? My big concern? Most of these internet experts- the ones who will scream the loudest- about things they know nothing about- will do just that when cam "C" makes 3 hp less than cam "J" As you know, there are so many variables as to why 1 cam makes omg! 5 more hp at 7k than another cam. I am glad you entered. I hope you and the others who entered all learn something from this. Good luck.
Man I love this challenge and how most of y’all are just trying to get data and help out.
Definitely, ty!!
This is similar to the testing for EMC (Engine Masters Challenge) that was a great learning experience. I really miss the competition and the great folks that brought all their different ideas and engines to the challenge. It was a chance to compare how well we compared with some of the best. Hopefully you will meet your expectations. Good luck.
Hope so, tyvm!
I’m glad you are doing this.
Ty!
the best part is we learnin folks!!!!!!!! let er rip!!! keep it going and we are gonna keep watching!!!! this is my favorite content!!!
Ty!
Cool vid
Ty
They are hydraulic cam grinds but running solid lifters 😊
Yes, pretty common
The lifters don’t know what the grind is
There is way more ego in the automotive world than ability. It doesn’t bother me if they are in proportion. From what I have gathered I think you have some stiff competition with Vizard. If you win it’ll make him rethink things. GOOD LUCK!!
from my understanding he isn't entered
It’s like open source R&D what you all are doing! Awesome stuff!
Absolutely 💯
Hey Daniel,
Tim here, yea, its a tuff challenge, as he aint gonna degree ANY of them!!.....the parameters dictate, that u shud know how much advance or retard to grind in, puttin it straight up, as well as other parameters, which i think will give GREAT DATA for ALL involved, and i think thats the BEST way to administer a challenge like this.....its fair for everybody, and we'll get GREAT DATA!!!!....i wanna see ur more aggressive dude.....just cuz i like aggressive ramp profiles.....knowing my bullet is properly prepared for it.....CANT WAIT!!!...
Definitely
I had to go back to his challenge. The 0.660" lift limit is instructive: port seems to back up after 0.700" lift. It may be that less is more in avoiding subsonic choke: could 0.648" be a good number? I wonder because velocity map seemed a bit wide [floor vs roof] maybe? Guessing at short turn behavior is best done by porters with a bit of dyno experience, and I am a hobbyist lacking dyno time [with an assortment of cams].
Anyway, all fun on my end: I'll be wrong and somebody will win - no time or cash to throw at anything right now.
The head is definitely not impressive, a good sqr port head will go close to 400cfm

@@powellmachineinc3179 YW, I hit the bell too.
You are wrong about it not costing anything for us to watch. Our time is valuable just as much as yours. This isn't a insult but I watch both channels and its like watching paint dry...
U like watching paint dry? U probably eat crayons while u watch?
