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!
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.
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?
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.
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.
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
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 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 🇦🇺
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.
You and your videos are in my top 2 now, along with EW. You communicate well, your explanations are valid, and you are humble. I will be working with you on my next campaign. I only wish you were closer to have you do ALL my machine work. I appreciate your willingness to compete, learn, and help others.
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.
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.
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.
I am learning alot of stuff from you guys already, thank you for participating in this! You seem like good people. I'm debating having a cam reground, and your on top of my list.
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
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!
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 :)
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!
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 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.
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!
Daniel! I'm a spectator on the sideline but, the content that you and other people publish is a learning experience. That being said, I appreciate what you do. and I hope the community does also. We benefit from the gift of your knowledge that you have dedicated years of experience to acquire. Thank you!
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 !
as soon as I saw Weingartners video announcing the challenge I thought Daniel Powell needs to enter this! I was stoked to see your name in the comments of that video! I'm a big nerd for engine data, I love seeing different engine combos and how they perform, this camshaft testing will be great data! Can't wait to see how the kindergartener stacks up to the rest..😁
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.
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.👍🇺🇸👍
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!
Thanks for taking the time to make your videos. I don't know how you have the bandwidth to get work done and shoot videos. Can't wait to see how you do in the challenge 🏆
I have this gift to see through and distinguish BS, and you obviously do too... That's why I love your videos so much.. Don't let the idiots knock you off track by making you feel like you have to set any record straight, part of their tactic is getting you to respond and take away your direction and energy. The things you do in the age we live in is just not what you and I would call common sense to some of these clowns..
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.
I support Eric myself. Have been a supporter and customer for a while. I have a setup now that should be a great horse power return. Unfortunately, I’ve run into a few issues other than engine and transmission related. I’m hoping to get the chassis issues that I’ve discovered after the engine build that has delayed the actual track testing.
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
I had not heard about this until I caught your video today, which took me down the rabbit hole of the challenge that Eric put forth. As you said it's going to be great data no matter who the winner is, what a great competition to host. I'm hoping we can get something submitted here from GPI to be a part of it, working on that now.
Ok, Tim here again, of cors i chimed in early, like i do......but u explained the donation thing better than Eric......makin me wanna give SUMTHIN to the cause, as i'm SUCH an engine nerd......i will DO SO SIR!!..and ur gesture of givin it back, speaks VOLUMES to me as to WHY i follow you guys in the first place, yes u may not win, but ur attitude is like his, he's no Superman, and we're ALL tryin to learn more.......well us engine nerds, NOT the armchair dudes......just LOVE it brother!!!.....
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.
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....
This is super interesting because all this data is typically hidden away. There’s many race teams in several motorsports that have done loads of testing and collected loads of data to try and find every bit. But, they aren’t going to share the details because it was so much work and money to get there.
You are absolutely right. With cams and all sorts of variables it's kind of like the English language, there are exceptions to the rule. No one person can grind a cam that works best for everybody due to many different variables. Carbs are the same way and people sometimes can't understand it's their combination that's making things hard and also you can't just bolt on a carb without tuning things other than jets and idle screws.
Wouldn’t it be amazing if we could have a different cam for the intake and exhaust valves? ..and imagine if we could somehow change the timing, lift and duration of those cams dynamically?
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.
Thanks for the video, I think we can all learn from this. Anybody remember those Crane aluminum valve spring retainers? 1978. 😮 Was Chase Knight working there at the time?
Yes sir. He has a really good channel as well. I've been watching his channel for over a year. And I've been watching your channel since your first video. You had less than 100 subs when I subbed to your channel. Well your primary channel. I saw your Cams channel pop up just recently. Month or so ago. Both of you guys put out some great information. I've learned alot from both of your channels. David Vizard said he was the first one to enter. Hmmmm!!! Funny I heard Eric metion you first lol. It does cost. Thank you for the info and the content.
@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!
@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 👍!
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.
I have asked other builders if a larger than 1.600" exhaust valve on a blown SBC with a 4.125" bore. Would see any benefits and all I got was that is what fits so that's what we run, which doesn't really answer my question. I'm just thinking that 1.600" valve is the one constant factor and I question if we are adjusting everything else to work around it.
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. 😳👍
"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.
In regards to selecting a cam for myself, I've opted for the smaller side that bigger. That being said I've always been street and strip. If a drag only car big is prob better
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!
Facts 💯!
Now that's a great response!
As David Visard says, I don't have opinions, I have a Dyno.

As you said it's going to be great data no matter who the winner is, what a great competition to host. I'm hoping we can get something submitted here from GPI to be a part of it, working on that now.
Good deal
Completely agree!
Ty
Ok, Tim here again, of cors i chimed in early, like i do......but u explained the donation thing better than Eric......makin me wanna give SUMTHIN to the cause, as i'm SUCH an engine nerd......i will DO SO SIR!!..and ur gesture of givin it back, speaks VOLUMES to me as to WHY i follow you guys in the first place, yes u may not win, but ur attitude is like his, he's no Superman, and we're ALL tryin to learn more.......well us engine nerds, NOT the armchair dudes......just LOVE it brother!!!.....
Ty, we really appreciate that 🙏
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.
Absolutely
It’s like open source R&D what you all are doing! Awesome stuff!
Absolutely 💯
I’m glad you are doing this.
Ty!
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!!
That's awesome man, love your channel.
I appreciate that!
Thanks for the video.
You are welcome!
This is super interesting because all this data is typically hidden away. There’s many race teams in several motorsports that have done loads of testing and collected loads of data to try and find every bit. But, they aren’t going to share the details because it was so much work and money to get there.
Absolutely 💯
You are absolutely right. With cams and all sorts of variables it's kind of like the English language, there are exceptions to the rule. No one person can grind a cam that works best for everybody due to many different variables. Carbs are the same way and people sometimes can't understand it's their combination that's making things hard and also you can't just bolt on a carb without tuning things other than jets and idle screws.
💯
I'm looking forward to the test and the knowledge learned.
You and me both!
I was waiting for this. How good your work is and how close your shop is to Eric's, I am surprised he didn't already call you for the cams he specs.
We are not close at all, he is 1000 miles from me, but we ship all over.
Wouldn’t it be amazing if we could have a different cam for the intake and exhaust valves? ..and imagine if we could somehow change the timing, lift and duration of those cams dynamically?
Hmmmm, if only someone would design such a thing.... they could call it OHC... lol
@@powellmachineinc just a Coyote guy being cheeky. Love your channel - wish everyone was as chill as you! Hope you win!!!!
Can you regrind Chevrolet 7.4 vortec stock roller cam they get pit marks on lobe and lifter roller
Yes, doing one now
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.
Thanks for the video, I think we can all learn from this. Anybody remember those Crane aluminum valve spring retainers? 1978. 😮 Was Chase Knight working there at the time?
You are welcome 😊
Yes sir. He has a really good channel as well. I've been watching his channel for over a year. And I've been watching your channel since your first video. You had less than 100 subs when I subbed to your channel. Well your primary channel. I saw your Cams channel pop up just recently. Month or so ago. Both of you guys put out some great information. I've learned alot from both of your channels. David Vizard said he was the first one to enter. Hmmmm!!! Funny I heard Eric metion you first lol. It does cost. Thank you for the info and the content.
The difference is I actually grind cams... everyone else order's cams.
@@powellmachineinc This is true!!! Lol. That's a difference like an engine builder and someone that just changes oil. Big friggin different lol!!!!
Excited to see all the info, I'll prolly never rebuild another motor, but who knows, i may win the lottery 😐. It could happen.
Lol
Thank you for what you do, I love this Chanel I like to learn
Glad you enjoy it!
Agree with everything said!
Ty
This has also lead me to new channels like yours. Everyone wins!
Facts!
Was a torque plate used on the mule and if so did you take that into account when you sent your cams in? This never gets old , for me anyway.
Na, it's of no concern
@@powellmachineinc I was joking.
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!
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 👍!
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.
Absolutely 💯
Can't wait to see the results
💯
They are hydraulic cam grinds but running solid lifters 😊
Yes, pretty common
The lifters don’t know what the grind is
I have asked other builders if a larger than 1.600" exhaust valve on a blown SBC with a 4.125" bore. Would see any benefits and all I got was that is what fits so that's what we run, which doesn't really answer my question. I'm just thinking that 1.600" valve is the one constant factor and I question if we are adjusting everything else to work around it.
The port would need to support a larger value, but definitely a 1.65 would help
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. 😳👍
My averages were over 600, on paper, crunching the #s I seen some thing that I new but just hadn't paid attention to with dynamic compression
Glad to see you taking a shot at this and glad some people are trying off the wall stuff even if it doesn't work. follow the leader is a boring game.
I agree 👍
It will be beneficial everybody will be making the same can from that point on if everyone gets to see each other's cams
"X" camshaft will only be optimal for a engine with these spec's, change anything and the cam will need to change.
David Visard has all of the information on the heads on his blog. Good luck Mr Powell
@@JamesBower-l9d Eric provided all the information, ty for the support
"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.
Lol, absolutely 💯
Eric doesn’t really sound like he’s “for sale”… 😂
@@dynamicmotorsports509that sounds like what the guy who already bought him would say.😂
In regards to selecting a cam for myself, I've opted for the smaller side that bigger. That being said I've always been street and strip. If a drag only car big is prob better
Definitely
Great video again
Glad you enjoyed it
I’m pulling for ya . I think it’s a great idea
Tyvm!!
Precision guesswork!!
