- CHEAP, JUNKYARD 5.3L CAM TECH! HOW MUCH POWER IS A CAM WORTH? HOW MUCH POWER WILL MY CAM MAKE? WHAT IS THE BEST LS CAM? WHAT IS THE MOST POWERFUL LS CAM? HOW BIG OF A CAM CAN I RUN IN MY JUNKYAD 5.3L? CAN I RUN A .600-LIFT CAM? HOW MUCH DURATION CAN I RUN? IF YOU WANT TO KNOW HOW MUCH POWER YOUR LS CAM WILL MAKE-CHECK OUT THIS VIDEO WHERE I RAN 8 DIFFERENT CAMS ON A 5.3L. STARTING WITH THE STOCK CAM, I RAN 7 OTHER CAMS STEPPING UP IN STAGES FROM 200 DEGREES OF INTAKE DURATION TO 234-DEGREES OF DURATION (NEAR THE BIGGEST THAT WILL FIT) TO ILLUSTRATE HOW MUCH POWER EACH STEP IS WORTH! WANT TO KNOW HOW MUCH YOUR CAM MAKES-COMPARE IT TO SOMETHING CLOSE.

Man, are we spoiled nowadays or what? Your stock LM7 cam makes more than 350 hp. Think of what it took to get an honest 350 hp out of a 1967 327 Chevy. Great job showing what a cam change will/will not do. As always, a lot of work and a lot of information crammed into 11 minutes of content.
Old 327s made that same power with a oe flat tappet hydraulic cam. They did have 11:1 compression tho
Rich tested a 327 in virtually stock configuration that made 356hp @ 6100rpm. Again, it’s at 11:1 compression instead of 9.5:1.
@@HioSSilver1999 That was advertised HP. With an iron manifold and a Q-jet, the L-79 struggled to make it. Look what it took to make an L-76 or an L-84 put out their respective numbers. L-79 still one of my favorites, though.
@@merylpelosi8485 he's tested them...they're comparable.
Ok, lm7 what's a good cam before you have to add mods to the engine, like new fuel rail ,pump and heads.
I appreciate all the work you put in.
Thank you for your time and effort to bring us this information
Thanks for the great video, compelling evidence and a great guide for selecting a camshaft
You're a life saver. Thanks for doing the work for us man. I'll know what to build now.
Thanks for another great video- one more vid for 5.3L 'LS' library. As always, we appreciate your efforts & the service you provide to the auto-enthusiast community.
I'm building my first LS based on your knowledge. Thank you!
Thank you Richard for including the broader dynochart starting below 2000rpm!
Thank you for all the information Richard. It is almost like a premium automotive magazine before the internet killed them, but in encyclopedia form with all possible information on the subject.
Thank you for your Service, Sir.
Excellent work again
Thank you for all the endless value you offer us, Richard!
Perfect timing. I have 11 min left on a read of a 3rd gen Coyote ECU. Moar cam tests!
it does take a minute to flash those
Install notched pistons and try more overlap (106, 107, 108) installed 4 degrees advanced and earlier intake valve closing. I know more overlap hurts drivability, but makes more power thruout.
In for all of the - "But Richard, what about this? And what about that? comments.
This is me thinking out loud...
1. That Crane 200 duration cam - I feel like a factory LQ4/LQ9 cam would make almost identical numbers.
2. I love that old Crane 224/232 cam - I have a version of it that I had Comp grind on XER lobes. I'll be testing that in my LQ4 swapped Silverado soon.
3. Thank you Richard for the plethora of camshafts compared in this video. Great data as always.
I think these videos should have vacuum readings! Very important for power brakes!
I just worked on 5.7 with a crow 1289 cam 236/254 on a 113 lsa,Higgins cnc ported heads I believe the lift is like 613/610 or something like that damned thing made 515hp at 6500..it's my new favorite ls cam.
As always, appreciate your hard work and valuable data. Cheers
The Summit stage 4 cam is very similar to the custom cam in my 6.4L 394Ci stroker in my Ram. Mine is a 233/246 112 +5degrees of advance, with 6.4l intake manifold, & 3,600 high stall. Didn’t want to go bigger on the intake duration because I wanted a really solid driving truck on the street.
And your telling us this because..........
No body cares bout ur ram ham this channel is bout LS engines brah so stick to ram ham channels. LS 💯 always!! Rams dodges suck ass
I'm running an LJMS 237/245 .610" 116 LSA on my SBE L33. No clearance issues using LS9 gaskets, shifts are at 8300.
Great video!
I watch your videos from time to time but now its a bit more impactful as I think I will finally be pulling the trigger on an LS swap for my hotrod. Plans are mostly stock but intake, cam and headers are likely the only big upgrades not counting any supporting upgrades like springs and such for the heads. And the largest reason for wanting to swap the intake is for the look, that big plastic thing isn't exactly appealing and to just be rid of anything unnecessary. Might even go with a carburetor intake and run a Holley sniper efi or similiar for that more traditional feel. Idk yet.
Didn't see the hot rod cam HP and tq? Great video showing the good stuff. Iirc all gen 4 5.3 have the flat tops anyway so I'm trying to go that direction or at least grab the bottom end out of one
Great information
I sold a .02 over 5.3L with a stage 3 cam from Summit. It went into a Mustang!
Gr8 video, should do the same test with the ls3 engine
lots of ls3 cam vids up
You should test Comp LST line Richard. People tend to think more aggressive ramps make more power. Thanks for content bro 👍
I have
Great teaching tool
Awesome thanks
RICHARD we need a late EFI ford 460 buildup to compare to the 454v496 video you posted the other day!!!!
Whats crazy is I did a 4in stroke to mine and even with the slightly bigger of the cams listed. That stroke caused the engine to make more tq than hp. I think the extra stroke combined with the restricted almost stock 706 heads shifted the max airflow to occur at under 5252rpm.
What are the numbers?
@@justinturdeau2383 it was on chassis Dyno in a 04 Tahoe with heavy tires and 4l60 so numbers aren't comparable and low. But still, it was 345 lb ft@4500rpm and 314 hp @5100rpm. Best part is I wanted towing and that's what I got. It has 300lb ft at 1700rpm and starts increasing slowly at 2k RPM until it plateaus from 4k-4500. So awesome towing power considering it's all right away.
Stock 04 Tahoe torque is 400 ft lbs @ 4,000 rpm. That worse than sucks!
@@DoyleShadduck You clearly don't understand hp numbers. This was at the tire without correction not some false stat gm gives out. GM inflates there numbers. stock on the dyno behind 4l60 is around 285-310ftlb at 4000 with a set of headers.
Could you do some testing with tick performance cams?
I wish gen 4 hemis had this much aftermarket support
I've been watching videos on 5.3's because I thought the 09 Sierra 1500 sle I bought from my dad had an LMG 5.3 (according to vin decoder). Come to find out my younger brother burned up the motor in 2019 and the only thing he could find quickly was a 6.0 that was supposed to go in an 09 Sierra1500 HD, but was a factory reject because of wrong angles on the cylinders. The machine shop my brother got it from buys these rejects and bores and sleeves them.
I've determined it's not flex fuel and has 862 heads. So I'm 99% sure my Sierra 1500 that I paid $5,000 for has a YL6 with less than 80,000 miles on it that had been sitting in a shop from 2010-2019. 😃
I wish the block casting numbers were in a more convenient location!
LY6, but yeah… sounds like you got a great deal!
Patiently waiting for Chrysler 2.5 2.2 content😅
I would love to see a Dyno shoot-out of the 3.8 V6's Buick, Chevy, and Ford to see which one makes more power
Geez, that S4 Summit cam was pretty respectable on the bottom end against the stock cam. I wonder if the Katech-ported heads propped that up at all.
I can guarantee the heads alone were worth at least 20hp.
Please please please do this for a Hemi, along with a comprehensive intake manifold test
Donate him a hemi the intake and all I'm sure hell do it those engines are expensive to buy from junkyard so are intakes and other parts ....
Great video. What of those camshaft would fit in a turbo application, make the most power?
the one that makes the most na power
Have you done multiple cam swaps on a sbf 302/351? I've looked and haven't seen one.
Would love to se a 5.3LS with L83 LT head swap and the BTR LT HEAD SWAP 230 CAM
Im stuck between the BTR stage 2, the truck norris and the tick performance towmax stage 2 214/224 | .571"/.561" | LSA114+4. Truck is a daily driver that sees some off road and snow, plus pulls a bass boat.
Think stage 1 in your case. TN if you don’t mind burning extra fuel and and having an erratic idle.
My new acquisition. Pure stock, ‘04 Cadillac CTSV, LS6, manual 6 speed. Can upgrade suggestion?
Power up to 3500 rpm was not very different from the smallest to the largest cam. This is probably the truck intake manifold dominating the midrange with its runner length. Were all the tests run with the same type of manifold?
U r the best
Let’s get it
I have to wonder if the average custom truck or hot rod owner could even notice some of the small incremental gains on these cams? Obviously, 100 HP is going to register on the seat-o-pants dyno. But, 10 or 20 horsepower is most likely not even detectable when out cruising on a Saturday night.
So basically when replacing a stock cam, it seems you need to at least throw in a stage II to see any significant improvement.
you will feel 20 hp
Richard, I know this is an older video but still waiting for you to go back and do the LS6. Camshaft, since the last test you did on it seized up inside the 5.3 and you felt it was an accurate on power gain. That was quite a while back. Any idea of when you going to retest the ls6 camshaft in a 5.3? Patiently waiting for that.
The LS6 was more than likely accurately represented-it does very similar to LS2 and LS3-nothing magic there
My trucks an everyday driver, 66 Chevy, work truck, haul wood, pull a 16' utility trailer.
I'm about to do an LS, probably 5.3.
Will the BTR Truck Norris do good on hauling firewood out of the woods, but haul Asspine at the top side? Add the eBay headers, maybe some 30-33lb injectors? It's a 3:73 rear.
It will help like the Texas Speed Chopacabra, but you can do a 383LS build, or do a LT1/LT4 (Gen 5)
I have a 01 rcsb truck with the Lm7 I’m full bolt on (long tubes, tbss intake manifold S&b intake) I also have injectors and a 340 E85 fuel pump. I wanted to know what cam you would go with to get the most horse power NA I also want one that would need a torque converter to make that jumó too
most peak?
Nice
In your cam shootouts, will you please start adding cams that are obviosly too big? Even the biggest cam here wasn't down on power compared to stock at 3000 rpm. Comments on idle vacuum would be helpful too. Love your content! Keep em coming.
He said that the biggest one in this test was probably the biggest you could run with stock piston to valve clearance.
Also, the 3000 rpm numbers on these graphs don't mean much, because that is the load in point. There is a major difference in the down low numbers of these cams, you just don't see it on these graphs
@@mikeday8826 and these low end numbers are important if it's a daily driver. I don't know why dyno operators don't start the pull down around 1500.
You know the LS is a beast when a stock cam with less. 050 than the gen 1 993 cam puts out over 350 hp!
@@robertwest3093 because a dyno can only measure about 3000-3500 of rpm range. So if they started the pull down at 1500 then it’d only test up to about 4500rpm~ well below the power peak(s).
When picking a stall for the cam, the camshaft manufacturers state to use for an example a 3500 stall but the cam has an operating range of 2500-7000, could use use a 2500 or 3000 stall, maybe somewhere in between or are there still underlying issues?
@richardholdener interested in the truck norris cam for my 04 tahoe z71 with the l59 engine. What torque converter you think will go good with that cam? Daily driver i like dogging it at stop signs sitting on 33x12.5 x22s
2500 or less
You should do a test with the same cam specs but different lsa
THAT VIDEO IS UP
I put a COMP Cams XFI RPM Cam in a in my neighbors 2005 Escalade, it felt like a substantial gain together with MagnaFlow 3" street series Cat-Back exhaust system and S1000 Diablo Sport AFM Module.
it has 228 Intake Duration at 050 inch Lift and 230 Exhaust Duration at 050 inch Lift.
I have a 90 C1500 with 5.3L built 100% as a stock reliable truck to be a workhorse. So far it is that, but I keep catching myself wanting to swap the cam. It seems if I was going to do that, the Truck Norris cam would be the way to go to not lose anything down low. Would you agree or should I just leave well enough alone?
I think if your truck works well just leave it alone.
I have ecu mapped my car cause it wasn't doing well etc... now 20% less fuel and way better.
Let's see this kind of test with a 5.7 Hemi.
Richard Holdener Will you do a lm7 engine Builds using 3.80 bore 6.128 rod length and 4 in stroke , 3.80 bore with 4 in stroke stock rod length , I want to know what the difference will be Using 706 heads truck norris cam ?
rod length won't change things
That's cool, let's keep posting cams we can't get and no longer available to purchase.
TN IS STILL IN PRODUCTION-BUT OBVIOUSLY YOU MISSED THE POINT OF THE DISCUSSION AND HOW THESE RESULTS CORRELATE TO EVERY CAM
@Richard Holdener Richard, love your videos but you're hard to follow. Descriptions are all caps, no model or part numbers posted. The stage 4 summit cam is no longer available, there is an alternative available that is close enough. A couple extra mins segmenting your videos and adding a true description with items/parts used in the video would go a long way.
thnx for the constant negative feedback, always appreciated, maybe these vids aren't really for you
@@richardholdener1727 Apologies if I had offended you.
Hey Richard any chance you'll get a Chevy 3.6L v6 on the dyno? Love to see if there's much more left in them when the camaro is 335hp stock!
Hey Richard run a 5.3 on nitro methane vs 93 dyno
You Happen to have a ms4 cam laying around over there. We have ran that cam in multiple stock 5.3’s and seem to work very well pretty rowdy cam. 239/242 .649"/.600" 111.5 LSA. Would be curious to see how that cam would do against others
I don't
What intake have you guys ran with that ms4 that works the best?
Man I’d love to see one of these tests on a k series or even better a b series Honda
they already have much better cams-but I have tested a lot of cams on B series
@@richardholdener1727 yes I thought a modern B series shootout more than an old school one you had already done ( still appreciate the old stuff )
I was wondering if you could add idle vacuum for us that are looking for a street-able cam? Brake Vacuum boosterable.
use the smaller cams
Hi Richard, I'm an Automotive Instructor for Job Corps and I teach tuning. I have an extreme amount of dyno training but for the IM240 program from Colorado/California. It seems to me that lobe ramp rate, location of opening / closing on the degree wheel and LSA have greatest effect on Vacuum at low rpms as I know you know. We are an emissions state and many people want to use their Vacuum boosters without going Hydroboost. In Washington State, we are allowed to modify but HP and Torque numbers can only help so far. I've been watching the videos looking for vacuum on your control panel screen during your dyno runs but trying to see them at idle is tough because the video is typically about above 2K rpms. Great videos BTW. Keep up the great work and videos! My students love them.
This is the LS bible :)
best cam to make the most hp on a stock 5.3? also doing injectors and will be on nitrous so didnt know what cams were meant to be naturally aspirated and which werent
get the biggest one that will fit-then be disappointed unless you are racing it
Did the L33 also have 2.0” intake valves? I believe the LM7 has 1.89” intakes
the l33 has 799/243 heads which have larger valves
I know you’ve done stuff with the Red Hot cam before. Can you do a video with a 5.3 and a Red Hot cam?
that vid is up-the Hot Rod is a better choice
if you used the same heads,manifold,exhaust,etc.... and did the same cam, say the stage 4 cam, what kind of hp difference could you expect from just changing the 5.3 to 6.0 everything else the same? im guessing about 1.25 hp per cubic inch.
please see the 6.2L (L92) stage 4 cam test video
Hey Rich... What's the max bore 5.3 cast iron ,and have you heard of a 4.0 stroke 5.3 383 cube 5.3 looking to fix my 07 Tahoe. Thanks. I'll keep watching
most go 3.902
Hey I found it... Thanks for doing what you do.!!!
Hey Richard can you run a test on the aquadale speed shop hog ass cam?!
not familiar with that one
Can we do the same for the 6.0
Best 8 cams
I copied your 6.0 btr stage 4 came
But now it's time for a new project... I love btr but what else is out there
65 impala coupe ss
Going big rims
Looking to cruise
Burn rubber and be snappy at the light when the pedal is applied 😅
THESE AREN'T THE BEST 8 CAMS-JUST CAMS TO SHOW YOU THE SPREAD-WORKS THE SAME ON A 6.0L
I am wondering if you have tested the Summit 8713R1 LS cam in a 5.3 with 243 heads?
no sir
What between what kinda horse power ?
I want to see a gen4 block 5.3 with l96 cam and different cams
see the ultimate cam test video
Awesome! I'm still stuck on choosing a bigger cam the vehicle is a 2007 chevrolet silverado 5.3. I currently have a BTR stage 2 truck cam 212/218 .553"/.553" 111 LSA with .560" springs and PRC 220cc cast heads, 4.11 gears, 3400 triple disk converter, 1 7/8" LT headers, the truck makes 370 RWHP I was looking for a cam to push it closer to 400 do you think the MADD MAXX cam would be a good option? Or change to a high-lift cam?
seems like a big power number for an auto and that small of a cam
I agree, it was surprising to me. It was done on a Dynocom it made 369.3 hp at 5,550 rpm and 367.9 Torque at 4,700 rpm I also have a LS3 ported throttle body and my truck intake manifold ported. I'm definitely thinking about the stage 4 summit cam now.
I don’t think that dyno is very honest.
Can you do a video for the l92 6.2 with the tsp honey badger, and truck cams.
Can you give us a good cam vid for Cali smog legal cams for an ls… that will give us some good power
I don't know of any
I got a 99 Silverado extendo with everything stock, what first mods should I do to get more power?
CAM, SPRINGS, TUNE
L78?
Whats the part number for the last cam and can you run it on stock pistons and valves?
summit stage 4
Hi 👋 👋 👋 👋 👋 Richard hay I wondering if all those camshafts would work the 4.3 1998 Gmc sonoma or the 2014 LUV3 4.3 what do you think.
different motor
@Richard Holdener hi 👋 Richard hay I know you where doing 5.3 V8 I'm hoping maybe you could try those same cams 4.3 V6 and the LV3 4.3 V6 I just thought they could benefit from 1 of those cams anyway thanks for listening.
Can you test just shaving heads at 0.5 intervals? See what making a smaller chamber and higher compression will do??? Please
compression adds 3-4% of power per 1 full point
@@richardholdener1727 so from a 9.5.1 to a 9.6.1 is 3-4% Is that correct ? Have ton done any controlled tests with that, or is it a major pain to do such controlled testing?
@@taraszakordonskk57319.5 to 10.5 would be a 3~4% increase. Compression makes your motor more efficient, which is where the power increase comes from. You'll also see better fuel mileage, although if you go up too high you need higher octane fuel (if you run WOT).
So a LC9/799 with a 210/218 .500 safe to assume 400hp/390 Tq?
yes
Interesting that the TN and BTR stage 2 cam have the same lift and intake duration, but the tighter LSA equated to more peak hp and tq, and started making power ~1700rpm sooner.
In fact, the TN cam made more hp and tq than the next 218/224 on a 110 cam.
I wonder why more LS cams don't have tighter LSA's?
no one knows…aka tighter lsa has been shown and tested to death to make more torque and hp than whats mostly sold
What I've gathered is it seems that tight
Sort of. On a cam if you shorten duration with same lift you increase stress on parts and the spring requirement goes up. So yes - that might be what he did - but there is always a draw back.@@KNS_Racing
I dont see much about a cam that improves off idle to 3000 where a truck will operate most often as a diesel operates ?
This is whats needed by a lot of people.
A cam that closed the gap vs a diesel.
Tick performance towmax stage2
@@The8ball365
I dont think that tow max max cam would come in as quick as a truck Norris or chapacabra cam since its on a 114 ls a vs the tighter ls a of the 2 i mentioned and wont have as much tq either due to building less psi of cyclinder pressure with the 114 ls a.
Are you ever gonna test any Texas Speed cams?
I have
Richard, have you done any tests with LS cams that advertise a lower starting Rpm band, like the Comp 54-424-11? The operating range is 1400-6700. Curious, as my rock crawler doesn’t typically hit those high rpm numbers.
there is no cam that makes good power gains from 1400 rpm to 6700 rpm-that is marketing
@@richardholdener1727 well, that’s unfortunate. 🤣. I’m running that cam I mentioned, pulls good and will still rev out if needed. It has similar specs as couple of cams you ran in this test.
not my first rodeo-how do you think your 212/218 cam with 550 lift compares to the 212/218 cam with 550 lift that was used in the video? It will do what that cam did
@@richardholdener1727 i definitely think it very comparable, although I hand ported the stock heads and run an LS6 intake….which I know is not good for low end power, but wanted it to keep my hood line lower and it looks better than truck intake 🤣.
it really does look better than the truck and (like the truck)actually works very well down low
Any thoughts on the cam motion junkyard dog camshaft, 238/254 .621/.604 115 in a SBE LM7
very big in a 5.3L-if it fits p-v, it should make good power
@@richardholdener1727 piston to valve clearance is my main concern. I'll just stick with the original plan & buy aftermarket pistons
Question for all .I have a 4.8 bored out to 5.7 LS1 bore size with LS1 pistons .what affect will the big bore have on it the torque and HP .it's all together .comes out to a 5.1 liter
a bigger motor will make more power-just like a 5.3l makes more than a 4.8l
@@richardholdener1727 what I'm getting at will there be any advantage of having a bigger bore and 4.8 stroke .rather than bigger stroke of a 5.3 and similar cubic inches .
there will be no gain from the bigger bore until you get very high in the power level and can take advantage of additional airflow that might be possible from the change in bore size, that might not happen until you reach 600 hp or so
now are we finally done with ls for awhile wheres all the coyote stuff of gen 2 and up
What would you recommend for a 99 5.3 cam. 33 inch tires I want to run a 3400 stall converter.
what power level and what is the rest of the combo
@@richardholdener1727 I was hoping you could tell me 😂 engine is completely stock as of right now
Isn’t the sloppy stage 3 Elgin 1841p more duration than the “biggest” cam shown here?
not sure on the ss3 specs
What's the cam that gives the best power in low range ?
see the results in the video
My summit cam will probably push over 50hp along additional hp from a tbss intake. And decked 862heads at .020. So. I’m guessing from the setup Richard has here I’ll be bumping close to a 80hp increase. On a lq4? Thanks Richard
Looks like for me driving on the street NA a cam change isnt worth the trouble of changing it lol
Chop chop
Depends on your application.... roll racing and ringing out rpm... top end power is valuable..... I shift my bolt on stock cam ls3 at 6500 but it wants more
@@Ws6Ms and I got 1 for a durability upgrade and a torque increase for a 293.
408 Stroker, AFR 205 heads, Yella Terra rockers, 233/239 .600 112 cam. 10.8:1 with ported trail blazer intake. 92 mm tb and full length 1 3/4 headers. Anyone have any idea what this motor should make? Hp/tq
500-525whp (575hp or so crank) give or take. Small cam for a 408, TBSS Intake holding it back and the AFR 230v2 would've been a better head choice depending on application. Should make a killer torque curve though.
it won't make 500 wheel hp
My Camaro with a 408 with ported LS3 heads and ported LS3 intake with a 244/254 .630/.625 113.5 +3 cam made 514rwhp in my camaro. With that being said your small cam and heads will suffocate your engine a lot. Let us know what it made.
would a comp 469 cam fit a LS1?
Don't fill sorry for me-if you compare two different people on a better scale-you have much to learn about life
Is there a big difference with these cams when using EFI vs. Carb'd?
the power differences offered by the cams are the same with either efi or carb
@@richardholdener1727 Ah, so it boils down to how bad you want to play with wiring.
