this guy knows what he's doing and shares knowledge. everybody should give him a thumb up. thanks for the good content. subscribed

Well Richard, I think this test confirmed what we already knew. But you can't be sure without testing. Waiting for that sloppy cam vs the world test.

“This poor little 4.8 has seen a ton of camshafts.” .... I know that wasn’t intended to sound sexual ....

So glad to see this tested. Too bad the results weren’t more impressive. Thanks for all your hard work!

I was playing with cam timing 30 years ago in my 3.x HP Briggs & Stratton push mower. My results were much more disappointing than yours. Thanks for the video!

Your videos save me time and money with the info provided. The info you put out is awesome

You need to do some LS or LT VVT cam testing!!! Use HP Tuners on a factory ECM.

Another fantastic video Richard, you really need to setup a tip jar so viewers can show their appreciation of your work. To find out concrete answers to questions like this is valuable stuff.

Spot on, exactly what I was wanting to see for LS9 cam, will save me heaps of time trying myself when in vehicle.

Congratulations on 60K. Those additional 10K appear to have happened over night. Soon to be at a million man.

That 4.8 is like the town bicycle for camshafts 😂😂❤❤

Congratulations on 60 thousand subscribers Richard. Well done Mate. 👍

Dispelling all the forum myths on a daily basis. Great video.

This video makes it easy to understand timing and the effect on the power curve

Richard, Paul Vanderley taught me when I started building engines. You are just as knowledgeable, and you give great examples to demonstrate/explain where anyone can understand. I appreciate your content!

This was helpful I’m swapping a gen III 4.8 into a Canyon. Got an LS7 cam gen VI. Was looking forward to knowing the numbers it can do. Not worried about low end loss I’m coming from 175 HP I5. I expect great things.

Great vid content. Advancing the cam moves the piston to intake valve clearance closer.

Great video. Lots of info and very cool to see this type of test.

Thanks, I have 494 big blocks in my propane bobtails. They run on propane through a "mixer" it is rated at 425 cfm.... my bmep noses over around 3500 rpm. We run the cam advanced as you would imagine...with 11 to 1's we get just over 500 foot pounds out of them.....not bad for .85 % of the power of gas and 1/2 the cfm of a normal setup.

You're the man Richard. I love your content

Richard you are awesome. I appreciate your time and efforts! I was excited to see this test. Along with you, not happy with the results but now we know how much the cam timing is worth. Great job brother! Thanks again. Keep up the great work! Sloppy vs the world is still exciting me ... haha

Pure text book!!! Keep up the good work!!

Thank you for all the great information. Planning my very first 5.3 LC9 build. And yes I'm going boost. What I have learned on your channel is absolutely amazing. Number one thing I have learned boost is good! I will be going with the razor blade rebuild! First motor doing it all myself wish me luck

Vvt for the win.. holley needs to get that into the term x system..

Now that's how you keep subscribers and make more! Pennies make dollars.. A lot of people don't get that but enough of these pennies and you can be rich... with horsepower and torque, that is. Awesome video!

This video offered great clarity in the subject of advancing or retarding a camshaft. Awesome content!!

Love your HF tools. My favorite 10mm cause it's the first one I find lol. The colored sockets are the best, and I;ve yet to break one. In fact the only sockets I have that are cracked are snap on.... You can tell a lot about a mechanic by the tools he uses.

Great video as always

Interesting idea keep them coming 🤘

When i was a kid i used to cut the cam bettween the lobes and weld it narrower on a b, s 5hp haha. Being as those ls cam are steel it would weld easy haha. Keep up the testing👍

holy cow!! I would have thought the results would have been bigger differences !

Good power up to 7000 with that LS9 cam, sounds like it'd be a lot of fun running it out!

This is great. Need more like this. FYI - you could do this via tune on the newer VVT engines!

With the lobe separation angle of that cam it's always going to be at a deficit until the very peak. A tighter LSA, shorter duration cam with the same overlap would bring in the midrange, give a lot more power under the curve, be more fun to drive and faster under almost all conditions.

Great test!

This was informative for off road build/Tune that run in the idle to 3K range. Richard could open/expand some video of his to this genre.

super cool test !!

Wow you're fast. Thanks a million

I love this video great content

I see a new Richard vid i like and move on this man deserves more subs 👍

Rich, this was fun but we all knew what was going to happen...let see what you can do with a VVT cam setup now.

Hey Richard, new viewer, love the info! I'd love to see some lq9 builds or even a "Self tuner Olympics" featuring self tuners on n/a, noX, boost, large duration cams, ect.... I'm really curious on how they can keep up. And 👍👍 on Happy Hour also

yes, GM does want to kill torque and throttle response. The wide LSA also lets them run higher compression ratio to get better mpg. Run a 275* cam with 110 LSA and watch out!

Just started watching your videos, and am loving the content. You are putting all kinds of LS specific content that is great, but was wondering if while you are at it if you could debunk some common myths? Like say is there any hp change with different spark plugs or wires like the companies claim? Or how much does a mechanical fan Clutch take in HP, Or electric water pump for that matter. Dirty oil vs clean oil, oil weights, oil filters, the possibilities are many! Maybe meaningless info but interesting nonetheless. Keep up the good work!

keep up the good work.

Good test. I'd like to see the LS9 cam cut on a 112.5 instead of a 122.5 but if your gonna do that youl spend the same as buying a better cam.

Ran a ls9 cam in a turbo 4.8 build I did a few years back. Didn't run a cam sensor just left it unplugged. No problems with stock ecu.

Great test, now repeat advancing the ls9 cam in a 6.0 with forced induction just to be sure!

Don't you sleep?!

I'm hoping you test some Tick Performance TowMax Cam's soon! Thanks for all your hard work!

Great video

I like the idea of factory upgrades for cheap. Richard if you do more on the K series engine, some of them have 50 degrees of timing adjustment. 25 degrees adv and ret.

We saw similar things back when 302 Fords were being built. The stock late model cam gears were retarded from the factory....add some miles with chain stretch and things got pretty soggy down low and in the midrange. Swap in a fresh OLD gear....which was almost 1/2 tooth advanced with a fresh chain, then throw in 4 more degrees advance and the motors would run a lot better. Well worth doing for sure. And one thing the dyno isn't showing is the sub-3000 rpm running which is where the advanced cam really shows the advantages on a normal street engine. Good video!

Very close to the question I asked a few videos back. About an LS9 with a 4.8 cam.

good info to know for guys running this cam with VVT.

I like the Harbor Freight ratchet and socket 😁

For the older guy's that owned Triumph twins (motorcycles) that was an option. Take the timing cover off set the gears to A or B.

So much for degreeing a cam in, on the street you would not notice any difference cheers from OZ.

Note out of Matt’s book, don’t look at your cam bearings or they’ll be bad.

Harbor freight tools ftw

LS9 cam specs: www.prestonmoore.com/2018_Sierra_L83/LS9_Cam_Specs.pdf

I think this is all relative. We still have a motor that makes over 300 ftlbs for the entire duration of its powerband. Yes it looses tq compared too the anemic 5.3 and 4.8 cams, but even on the 4.8 it STILL exceeds 300ftlbs for the entire duration of the tq curve. Thats perfectly drive able. Your not beating the shit out of your valvetrain with crazy lobes and not sacrificing any driveability. Would this be the best choice if your towing? Obv not. But for a street vehicle its gonna be cheap, really reliable, and make tons of power when you open up the loud pedal. Seems like a winner.

thanks for the vids :)

Was hoping for more gains down low , since I'm running one lol . But with a quick spooling turbo I don't really lack low end torque . Thank you for the test .

LS 7 cam is looking good.

This is gold

I advanced a cam 4 degrees and picked up 4 tenths on a 388 SBC. I would love to have seen dyno numbers to know what changed, besides it making more torque down low.

Gen1 torque monster eg rv cam vs 5.3l ls gen 3 or 4. Can the 5.3 compare the the gen1? Who will make more torque? On the street it’s all about useable torque at street rpm. Another great video,

nice test

I see that purple Harbor Freight socket, I have the same one!!

So, how many engine dynos have you just slap worn out? Great channel, answers to a lot of the late night bench racing "what if....." questions.

I grabbed a ls9 cam for my truck and yes I can attest to the loss of bottom end. It was the cheapest cam even cheaper than bone stock. But I can say since I put in the 4:11 gear it kinda made up for the low end loss.

I would like to see the LS9 cam versus the Lingenfelter GT2-3 in a LQ9 with the STS-V supercharger. Since the LQ9 is 211/230 .562 122.5 and the GT2-3 is 207/220 .571 .578 118.5. The GT2-3 was the "gold standard" for the MP112 and MP122 for the longest time but the LS9 obviously has more duration with a little less lift.

Pretty cool, tinkering

I'm glad I'm not the only one who noticed the chain slop!

Rich, I'd love to see a test of hp/tq changes with coolant temp changes from 140*-230* Also the effects of A/F with coolant temp.

The LS9 is 125$ shipped on amazon! With a turbo LS setup IMO, the last thing I want on street car is more power down low.... boost takes care of that easily. Great cam for the $!

I think it’s pretty cool of adjusting the time in like that or the event but I’m wondering what would happen if you change the rocker arm ratio from 1.7 to 1.8 change the left on the cam I Wonder how that would work

Thanks I resemble that remark.

Richard can you get a JY explorer 5.0 and do this test with a stock HO cam? I figured explorer motor would be the most common configuration with the GT40 setup

Please do some Texas Speed Cams. 220r, 224r, 228r etc in a 5.3

Richard have you done a video on spark plugs. I’d love to hear your input on hp and na vs boost apps.

What would happen if you mixed a bunch of popular Chevrolet engine parts 5.7 vortec block lt1 internals and a tpi intake??

Another question answered! I’m thinking the super-wide LSA kills the mid-range no matter what. How about the same test with the LS3 cam? It doesn’t have much in the way of overlap, but more than the LS9. OTOH, an extra$200-$300 gets you a real aftermarket cam that works. Never underestimate the effect of torque on drivability, though. Not so much if it’s a drag car, obviously.

Engine will start and run with no cam sensor... I ran my LS7 that way running a Jesel belt and no sensor. it’s a little like roulette odds and evens as the engine may be 180 out and pop out the exhaust on crank.. I just re cycle the ignition an go again and most times it will fire up on the second or third attempt if it didn’t go on the first hit

On top of losing torque, I'd have to get the right sprocket, different timing cover and move the cam position sensor and hope it works with my stock ecu all this cost money on top of what the LS9 cam would cost me so I'd rather just get a summit truck cam for only a bit of extra cost

Hobo Fright in the house!!!🤠

I knew it wouldn’t make as much of a difference as being ground on 112+2, but I really hoped the torque curve would be in the middle of the stock lm7 and ls9 installed straight up. It’s a dirt cheap cam, but not good for stock truck application or daily driver.

amazing good vidéo this winter i am instaling ls9 cam / spring on ls6 stock whit help off 400 off NOS the trany have 4500 stall .......well se the result 😁tanks merci bien

I’d like you to finally kick the LS 9 cam to the curb, and buy a 209/217 cam from Summit and run that. Show us what a higher lift mid range cam can do.

Richard should look at the Ford barra engine and intec all 6 cylinder here in Australia. Intec shoc 6 cylinder with only 35 pound's off boost doing 7.5 over quarter. road going barra 6 cylinder putting out 2100 hp at rear wheels all on factory blocks and heads of course there billet internals .dynamite performance has a dodge avenger prostock with a barra in it destroked running 50 pounds boost over 2000 rwhp 10000 revs traction is a problem. Considering a mighty 2jz running 100 pounds boost billet block etc Ford coming real fast.

The flip side of this is, that for a light car (sub 3000 lb), this is a great low buck option. Tires are expensive and only get so wide.

I live above 5000 ft. altitude, and I can't ever remember retarding a cam. I think we always tried to keep the lobe centers between 108 and 112 degrees thinking it would help trap cylinder pressure. We might use smaller runners and intake valves to help port velocity.

A 2 piece timing cover sure would have come in handy on this testing.

Does anyone make a continuously variable cam timing system (VVT) for LS9? Best of all worlds!

In my experience I've noticed to a certain degree wide lsa cams start losing top end hp pretty fast once you start advancing them more than a couple degrees, more so than on a Narrow LS cam I'm not sure if it has to do with pumping losses or where the exhaust valve is opening and closing, this test was one of the least drastic I've seen on this type of test, and yeah Richard do you ever sleep? My goodness

Maybe the stock 6.0/Ls1 cam would be the best bang for the buck here. Already a 3 bolt rear cam sensor, and doesn’t loose too much down low compared to the LS9, if my memory is correct. And they are a dime a dozen. And the LSA is 116 vs 122

Ha ha ha ha lol I like the shirt bro

Have you ever tried the 5.3 with the ls9 cam and about 15lb boost on e-85? I wonder how it would work out.
