I am suprised that so many entered, i thought few to none would enter... there will be good info that comes from it.

I am sorry to hear about your son. Looking forward to the cam video. Am looking forward for more of your work.

Subscribed an Amen to "LS is a different animal." Some local amateur results are suspiciously good to say it that way. :)

Hey Brian, Tim here, my man Powell sent in 2 cams, we need another dyno day, my goal this eve is to donate to Eric, so we get another dyno day.....Daniel (Powell) said a simimar thing, his main cam is good (he'd stand by it) but his extra cam is more aggressive, etc, and he DOES grind his cams, and he's done ALOT of LS stuff......i need to donate!.....i wanna see all u guys competing, NO he hasnt changed any rules (utube couchers).....the data obtained for ALL involved i think will be priceless, but, we got heavy hitters, You, Powell, Lykins, Summit, and Vizard is supposed to get his in....QUALITY engine folk.....i cant wait!!....i sub'd a few months ago, so i AM a diligent/loyal follower.....i wish u the BEST!!...lets see.....i LO E that serious engine builders have all chimed in, it shud be a BLAST!!...PEACE to you sir!!

Amen brother , I sent in that Comp cam 243/246 and I told Eric it was specced for 364 ci 6.0 and I expected no hp number just wanted to help him out with participation because I love DATA... I believe Eric is a very stand up guy... I agree the dyno graph of those 2 cams looked odd for those 2 cams to peak at basically the same RPM makes me scratch my head a lil... I don’t think it was anything intentional on Eric’s part... just looked like something was limiting RPM ... I currently run a 231/235 107 LSA in a 364ci 9.4 compression stock bottom end stock 317 heads with .600 lift flow at 252cfm LSXR-T intake and 102mm TB. Comp cam link bar short travel lifters quality correct length pushrods and beehive springs with tool steel retainers and it will easily go to 7300 rpm with no loss. I think you’re right a day or two on the dyno and that 408ci could be sorted out ... I think what Eric is doing is really great real world data ... keep up the good work Brian thanks

hi, what do you think the h.p. spread will be? more than 20 hp?? Or? I would not be surprised to see only 10-15 hp between the "winner" and "losers"

thanks im doing soild rollers today

Knowledge is power.

Wow! Priceless hard-core tech. I would like to hear your thoughts on pin offset. Or maybe I missed that one. Thanks for the video

Hey, it's your mate in Australia. Could you do a video on advancing cam timing. My application is a traditional old school GM inline 6cyl with a little boost, 9lb, turbo . Very mild hydrolic flat tappet factory cam, with upgrade from standard 1.5 rockers to 1.6. Will use multi keyway crank gear, no chain just cam and crank gears. And dialing in and pro's and con's. 2-4° or how much is safe and best. Any piston to valve clearance issues, any ignition timing changes. Only going to be around 370- 380 " lift, not much duration. Your videos are very good that I've seen.

Amen! 👍👍 to all you covered. I've been subscribed since you re-educated me on the long rod.

I guess u turned the dist back or to the left clockwise

Like David Vizard said, some will come up with very aggressive ramp lobes, but like you and David are is making a cam for a street engine, I hope Eric is fair to point out which are the more realistic street cams that will not destroy the valve train vs the ones that send their cam profiles just to win the challenge.

I saw the same video and I believe the same thing as you, I think it has something to do with the overlap. We don’t know what that was

More air, more fuel, more power, if some of these cams move more air is the engine going to go lean and detonate? No jet changes right?

Amen brother

Cam shaft might make a difference because the valve events may require different specs for a short rod setup as the piston is excelerating faster after TDC so would the cam event have to be different?

I'm not sure why someone wouldn't subscribe if they like content like this?

If your like me and don’t have FB. Or pay pal. Yes I’m one of them. I was able to email Eric and he sent me way to donate for the challenge. I’m not an engine builder professionally. I do my own for my mopars. I’m a body n paint guy. But I think this is an event everyone should be interested in that watches these car channels.

I couldn`t agree with you more! We are not racing dynos! I built engines for a number of differenrt venues. I have few a champoinships and dozens of checkered flags from a number of differt type racing series. Drag racing is the least of my sucecesses. I generally build for torque over the widest range I can get. It just works thats why, I`ll give up 50hp for 30lbs of torque all day long. These unconcidered conciquences(which I mentioned earlier)can have a role in this outcome. I can`t roll my cams cause I don`t have a cam doctor. I assume you do, if theres a dicrepency in the timing components which( we have no control of) may hinder or help somebodies elses cam specs. This test is outside of the box. If I sent in a cam it would be .050 over the max flow lift. 256/262 at .050 with a 106 LSA with a 102 ILC. What do I know anyway.

I appreciate your teaching.

For one, the piston weight is lighter with the longer rod, but..the rod weighs more, is the total of both the same weight ?

Ben Alameda always says that dino results never translate in the 1/8 & 1/4 mile !!! 🤔

There are many people that will do exactly this,and that is go buy a cam and stick it in their engine,dot to dot and thats tje way it will run. No dyno tuning !!! But simply because they have no access or the time or money to dyno their stuff. I am glad and thankful for these types of videos. The info will be helpful. Thank you guy’s for helping us little guys 👍🏻

I and others donated to Eric to add an extra dyno day. He e-mailed us over the weekend to let us know he received enough for an extra day, so we should see 14-15 cams in the test. I'm willing to donate more if needed. We're going to learn something, and that's exciting.

Very good incite on intake velocity, inertia, reversion, and the fact that the valve is in the low and mid range lift most of the cycle !

I personally don’t like LS engines!!!! They maybe great , just don’t like them!!

I’m subscribed and waiting for the new shop!🎉 🎊

Lol big valve ls3 head dont need alot of cam to make power. They are different animals you are right

Thank you for your knowledge and videos USA 🇺🇸 TRUMP

Man it's gonna be a long month waiting for results, hope you do well..

Just my two pennies: a larger hydraulic roller camshaft on a 108 will have a ton of overlap. That's why the 241/243 cam didn't do as well. You're just pushing power right out the exhaust pipe. There have been instances where I have made more power for customers with less camshaft. Good luck to your entry!

This is the most exciting thing to happen in our life. I thought I got an education in school but this...this is going to be epic!!!

Holy cow! 93% not subbed!! If my math is right, that puts your sub count out to 100K if they were.

Brian regards from Sydney Australia!👋💪

You weren't the only one that expected much better results from the 241 cam. I know the tight lsa hurt it at the top, but still....

I wonder if the ls Dyno mule has breathing characteristics similar to what hemi heads are like in respect to cross flow @ overlap?

The winning cam probably not be the fastest at the track! Bet winning cam could even be near slowest at the track... I hope I am wrong and you can tell more from the dyno sheet. Do you think you can look at dyno sheet and know which cam is best?

Dot to dot is so vague, brand of gears, can be so variable, how stretched is the chain, you really need to narrow all the variables down to grind offset in that cam.

BIG Difference between Engine assembler and Engine builder

Good luck. Not sure but I've heard Eric is slippery to deal with.

Less than 400 cubes N/A making over 900hp 😮

People already making excuses and the tests haven't even started !

Exciting stuff. Congratulations for your son. God bless.

What do you mean he didn’t change the rules. I’ve heard him change from 91 to 110 octane after a competitor requested it and he now has three pushrod length options vs one to start with. I’m not in the USA but I know I would definitely send a different profile for those two octanes.

Found your channel because of the challenge, so its already done some good. I have a lot of literature from a guy that I've read for years and liked, but lately he's been doing a lot of talking and not much acting. I want the cam to get to Eric, because I want to see something other than, "I'm right because I said so."

Keep up the good work Brian We are all looking forward to the results V8's and camshafts profiles How good 👍

Yeh man, LS are a different animal! I’m seeing some crazy power from sub 240 intake durations and can’t wait to see what wins the challenge.

Will Eric be handing out Participation ribbons for the contestants?
