The Camshaft Challenge

Small tip hope to see @DavidVizard and @BTR

[@WeingartnerRacing]

Thanks man. I do aswell.

[@ratherbeboating10]

I had jones spec out the cam for my 388. Seemingly nice grind, nothing crazy. Told him what I wanted to do then asked if I was being realistic. He recommended something a little more tame for the street. Engine isn't finished yet but I gave him every data point he asked for. Great to deal with and got me all the ancillary parts too. Love the video Eric as always. I remember a while back reading about a few grinders in a contest with Vizard and in the end no runs were made as the grinds were all nearly identical. I suspect those who are truly good will end up splitting hairs. It's the alleged experts who'll be all over the map...

[@lukesimeon5756]

Good stuff man ... if you talk to DV and he agrees tell him I’ll pay his speccing fee and I’ll pay for the cam .., and 1 thing with all due respect am I wrong in thinking the 1 3/4” headers are a lil small ? What I mean is if you had a big block Chevy with exhaust ports that flow 250cfm + I don’t think we would put 1 3/4” on it and expect the best results IMHO

[@WeingartnerRacing]

Most run that size headers

[@e85lenkkari]

Best challenge ever!

[@robinfulton9057]

Daniel from Powell Machine turn me onto you channel. Looking forward to following along.

[@Chainsaw-ASMR]

Same

[@v8packard]

I can budget for one. I will probably have it ground by Cam Motion or Jones. Most likely will be a 8660 core, three bolt. I can probably get this going in the next week. I have no problem with the timing points being shown, and I will give what I think will be a good installed centerline. I will base the cam on your provided engine specs, as well as your stated 4000 to 7000 rpm test range. If I have a question on any parameters I will ask you. I want to be clear and agree on the parameters.

[@WeingartnerRacing]

Yes any participant can ask many any question about the motor. I will give all information except what other participants cams are.

[@v8packard]

@@WeingartnerRacing Stock rocker ratio, correct? 6.125 long rods?

[@WeingartnerRacing]

Yes 6.125

[@v8packard]

@@WeingartnerRacing Might sound odd to your tight LSA crowd, I am coming up with a 112 to 113 degree LSA for this combo. I will work on this some more and be in touch.

[@chrisreynolds6520]

​@@v8packardI do not have a horse in the race because I am just a hobbyist without the deep pockets to do this. I ran through some engine modeling and have a fairly similar LSA point. Those tight LSA fans would be surprised how much less overlap they actually need with a high flowing, efficient port.

[@jcnpresser]

I hope this goes to at least ten, think it’ll be freaking awesome.

[@philminotti6870]

Thanks!

[@JG-kv4oi]

I'm no camshaft expert by any means but I'm thinking tighter LSA is more important on heads like OEM cast iron SBF. Wider LSA in my mind like 112 is better for more efficient aluminum heads. By no means a LS boy here, SBF all the way but I'd hazard a guess for 408 LS at 8.6 dynamic on pump gas, 250@.050 intake 256@ .050 exhaust .650 lift at the valve, 112 LSA. You're welcome to tear my comment apart viewers 😊

[@GrandPitoVic]

NOT A CAM OR ANY OTHER EXPERT Eric!!!! Right here. I'm your first. We'll I admit it lol. I know less about cams than I do women. And I've been married 24 years lol.

[@jeffwooton7138]

Whoo boy! I love that you've thrown out the challenge. I am NOT a cam expert. I do watch and read what many experts have said. I analyze all the info, make a decision, and live with it. This is just gonna be more info for me. I cannot wait for this vid to come out. As a side bar, I'm not all about max HP. I prefer torque, and a good "flat" torque curve. That helps move the mud trucks in the playground. So there will be good info obtained in this upcoming challenge. Cannot wait.

[@WeingartnerRacing]

Max is only half of the score.

[@alexgillies4183]

Now that's throwing down the gauntlet! You'll get your 10 camshafts, no-one can resist the chance for internet fame 😄. So great that DV is onboard, he's someone that would fully agree with your "prove it on the dyno" philosophy.

[@deankay4434]

I am an ASE Master Tech since 1978. In reality, this doesn’t mean a hill of “Stink Pickles” because I just diagnosed them and fixed the root cause. I don’t build them, I never ground a camshaft in my life, and find this interesting. I simply can to KZbin several years ago to purchase products to make my engine run, paint my 50+ year old truck, so I had something to drive until the Lord calls me home! I find your cam challenge interesting and will subscribe & watch. Why? Because if 1 guy or gal in a 1,000 can put down their X-box and build an engine, grind a new cam, count me in on this project! Thank you kindly for sharing.

[@bigbad253]

Hello Eric, people are the same everywhere - there is always a mix of mostly decent folk, with the occasional loudmouth, braggart and troll thrown in to cause some upset and chaos. As a 17 year old in Australia in the very early 1980's, I purchased a very secondhand 1969 Holden with a 253 CID V8 that some absolute wizard had put together. After I replaced the 2 barrel stromberg with a 500 Holley, it turned the power even more! People either loved or hated these little V8s based on little more than someone else's opinion. I was always happy to change someone's mind by taking them for a run, or have a little race (conducted on a closed road with all safety precautions etc....of course). Excuses become a very important fallback position when presented with evidence - one guy who I beat five times in a row because; I obviously jumped the start, he spun off the start, the starter allowed me to cheat, thought he saw a kangaroo and backed off, finally concluded that his car needed a better tune and we would run again (he never showed for rerun number 6). I suspect that a couple of fair-minded people might accept your challenge, however I look forward to the excuse-making troll who proclaims you "didn't do it right." I hope he gets locked out of his Dad's pornhub account.

[@god1st.530]

​​​@@jimwilson4639I what Eric is dealing with is the GM LS platform is 2 decades and some years old. You got guys like me that have already and still grudge race LS motors that means if my car is a 2000 Z28. People like me already know an been through every possible trick , performance product the world has to offer I ran 80s 5.8s in a full weight sbe Gen 3 Th400 4k stall small tire with a plate kit way bk years ago of course people like me are gonna have some input I was 20 years old then and now I'm way faster than that . Then you have the mid way through crowed that LS also put deep memorys in their minds and they may still race idn. But Richard Holder already did 1000s of GM LS combo testing. That's another hurdle Eric has to climb over look I think 💬 Eric is Stright up and the fact he is in tune with his subs show me that he's actually better at KZbin than some of these guys that been at it longer than him. Why couse he is the only guy that does KZbin in a non it's bout me im right y'all dumb selfish push his own agenda Way. That's very rare on KZbin.

@@WeingartnerRacing For sure family obligations come first! It was just a thought that popped in my head because I know how shops are as I am sure you do as well. I am VERY curious about this. I think you have come up with an excellent idea. There's only 1 other thing I can think of that some may gripe about and that is using some sort of adjustable cam timing set to ensure each is installed exactly as the grinder intended as I have heard time and again how just slapping a cam in is not correct, even though that is how most folks do it. I hope this works out as well as I think and you envision because this has "epic" written all over it!
