HOW TO PICK THE RIGHT LS CAM-STOCK vs TRUCK vs PERFORMANCE CAMS (DIY CAMS, DYNO & HOW TO)
HTML-код
- Опубликовано: 4 сен 2024
- WHICH CAM IS BEST FOR MY LS? TRUCK CAM OR PERFORMANCE CAM? PICKING THE CAM THAT IS RIGHT FOR YOUR APPLICATION IS ACTUALLY NOT TERRIBLY DIFFICULT. CHECK OUT THIS TEST COMPARING THE STOCK LM7 5.3L CAM TO A TRIO OF BTR TRUCK CAMS AND A MORE PERFORMANCE-ORIENTED GRIND FROM COMP CAMS. WHICH ONE OF THE TRUCK CAMS IS THE BEST CHOICE? HOW MUCH MORE POWER DOES THE BIGGER, WILDER COMP CAM MAKE THAN THE MILDER TRUCK CAMS? HOW DO THEY ALL COMPARE TOT HE STOCK CAM? WHICH ONE(S) WILL REQUIRE A CHANGE IN CONVERTER? IT'S ALL HERE!
And just like that , 54-454-11 will be "out of stock" at the blink of an eye . Great vid
Now does it need springs ? And new rockers ?
What springs and rockers did it have before the cam swap , where the rocker trunnions upgraded ?
@@privatedata665 stock every thing
Your work is timeless and priceless, thank you so much
you are confirming my choice of the BTR Torquer truck cam for my son's '08 Silverado 4.8. He doesn't run it out past 5500rpm so there was not point getting a bigger cam. the shorter duration of the Torquer truck cam tilts the power curve to the right and gives him more power and torque below 5500rpm where he uses it 99% of the time!
great video!
Thats what he says
My thoughts exactly 😂
What do you think would be a good cam swap for a AFM/DOD delete in a LC9. I’m considering POSSIBLY doing more to my truck. But if I don’t what would cam would still be dependable
I will now call you Professor Holdener. I learn so much on performance from you. Thank you sir
Wished LUNATI would let you test some of their VooDoo cams. Be nice to see what Harold Brookshire had up his sleeve designing them.
Send him one.
Love my 256 voodoo in my mopar 383...awesome cam!!
Stage 1 for the win bang for buck and with stock convertor the driveability will be the best by a mile! 👍
Trucknorris cam for the win
Yes! Truck Norris cam please!
Well done. I think I'd stick with the stg 1 truck cam too on an actual truck/suv app. My stock 4l60/LM7 Tahoe stalls out right around 2300-2400 rpm on the stock converter so as long as the cam doesn't lose anything from 2500 rpm on it's a good street choice.
These manufacturers really got the stages dialed in. I am running a stage 4 and it's just right for a truck that still sees work. I think if your truck is race only, you need to go slightly bigger than typical truck cam. Because with my stage 4 I don't feel like I lost any low end at all, I could afford to go larger. Especially if I stop hauling around a bunch of tools and materials. But this is with 4.10s and I will be switching to 3.73 soon so we will see how I feel about low end. Right now it hates the back tires anywhere under 30mph so I'd be happy to lose some low end lol
Thank you for having the test results right upfront it is very much appreciated, stayed for the testing and further insight.
How to pick the right LS cam :
1. Call Brian Tooley
2. Give him your money
Nope id go with comp cam or even better texas speed
I’d run, summit, tick, and Texas speed before btr.. hell I’d find an old lunati voodoo cam first.
@@matt6951 Why?
@@matt6951 Or even an Elgin P1839 or P1840. The money saved will pay for the valve springs.
So what’s the reason yall dont like BTR stuff? Dont throw shade without giving some reasons.
After putting in a BTR torque cam in my genIV 5.3l and unless I drive in manual mode, my truck shifts at 55-5700. So on a daily, your never really using 5500+ rpm.
For a daily 5.3l I would suggest:
BTR torque cam
Speed engineering 1 3/4 headers
And a Cold Air Intake
I’d suggest a turbo.
@@matt6951 If I had another vehicle to drive it would already be turboed.😁😁
@@matt6951 That's what I'm in the process of doing.
Great work as always. However I can't help but think most of your viewers will be using these for road use. It would be nice to see the bottom end of th Dyno graphs.
I don't know about y'all but I never get tired of this kind of content!
Looking forward to the Truck Norris cam test! Perhaps in a 6.0l as well? Time will tell?
Is the truck Norris cam available for purchase allready?

I’m building a 5.3 for my 2001 YukonXL hunting vehicle and using the BTR stage1 with BTR valve springs with the BTR trunnion upgrade. Your videos helped me pick my ‘poisons’
All great points , more inches is always a win down low.

Then running a stage 2 Truck cam in my 6.0 with a Trailblazer intake, some 243 / 799 heads milled 30,000 with my Detroit truetrac 488 gear & 35" tires, thats the plan, I'm getting there, its gonna sweet, IT'S ALL YOUR FAULT RICHARD!
funny they call them truck cams. My idea of truck is low end torque. retired truck driver so always wanted to be able to pull that hill without shifting. drag racing and winding out to 6-7000 isn't my idea of truck. I would think torque cam or race cam would be better marketing. sure it depend on what rpm you are running but if a street car or truck cruising is usually 2-3000 rpm even at 80mph. race car wind out to 7000, shift then up to 7 grand again. Great videos Richard.
Yeah I agree, low end power is the #1 if you're building to tow. You'd be looking at boost or more displacement rather than the biggest cam you can shove into your engine
a pro ls summit 8718 cam 500 lift 205/217 at 112 its small really for a stage 1 anything lol its stock 5.3 valve springs still an it added really noticeable gains...granted im running a 3800lbs elcamino its 2500 rpm thru 5500rpm aint horrible if your inside for any reason an just curious...try it what's 300😉😉but i run Fitech ultimate ls system so im still learning ls tuning period....
I never understood why you want any of those, especially in a truck. Most of the time I'm running a truck around 2000 rpm or less, rarely up to 3000 rpm, let a lone 5000 rpm or more. Currently driving a 1996 Dodge extended cab with a 6 foot box, 1/2 ton 4x4 with the crappy 4 speed automatic and the 5.9 liter 360 gas with 33x12.50-15" tires making about 10.2 mpg. I want torque at low rpm at highway speeds or 55 to 70 mph in 4th gear.
"I want torque at low rpm at highway speeds or 55 to 70 mph in 4th gear."
Everything comes with a compromise. What you want could only be achieved by increasing engine stroke/adding forced induction or doing a Cummin's swap, otherwise you're limited to changing your gears to match you're desired torque at given RPMs. But your limited use of your vehicle doesn't mean everyone else is going to be using their truck or these truck engines in the same way.
There are so many different uses it's baffling that you "never understood why you want any of those, especially in a truck.", I think you need to get more exposure in the world. Not everyone uses a truck for low RPM or towing and not everyone is using these "truck engines" in a truck application.
I find that, as a light duty truck, my '96 Ram 1/2 ton with 5.2L has a great blend of low end torque and midrange with the 3.5:1 gears and the same stock crappy 4 spd auto. It only has 31's though. But I have no other uses for that truck other than to haul stuff from Lowe's. My K5 Blazer on the other hand isn't primarily intended for the same application and is more of a weekend warrior that would be more fun with another 100hp on the top end for the 5.3 LS that's in it.
I will help support the test of the BTR Truck NORRIS CAM !
I believe that stage one cam and a turbo would be delicious... And I stayed until the end. We are loyal out here
Incredibly good info. I've always thought for my purpose, anything but a mild cam and headers is wasted. The TBSS intrigues me as well, but I don't know that I'm capable of properly installing it.
Super easy to install. Did it on mine in a weekend. Contact me if you want assistance.
Richard, I see people stating that Comps Thumper cams are for sound only and don't make power. I know that isn't the case, but would love to reference a RUclips video to prove it. Thanks
Even the cam designer at Comp said it was a marketing thing only, they are a terrible idea from start to finish for performance. ;) And Comp isn't exactly in the game of high end cams as it it, their "new" LST technology has been around for a long time, but they'll make the power that the dyno says and that might be enough after all. :)
A somewhat good gas mileage approach would be the highest amount of tork an the lowest hpm.
Try a stock type dur cam with more valve lift or bigger valves with a small to medium turbo. Open the valves briefly and force feed the cylinders
Bv
I too would like to know about "truck norris" cam.
Heads up LY6 req heads up... Truck Norris verses the SDCP Hot Truck1 cam.
You can do it Richard.
never heard of the scdp cam
If I’m not mistaken the summit stage 4 LS cam actually made more than this cam by quite a bit. 475 horse on a 5.3 if I remember correctly
Stage 1 ground on 108 or 110 ... as much time over 400ft/lbs under 5500rpm and 400hp/minimum is my sweet spot. Great numbers for 5.3 liters .. 1.3 hp/cubic inch is 423hp on the 5.3.
Yes we need the truck Norris comparison ASAP please!!!
Stage2 TEXASSPEED in my 99 Z-28 350hp 350tq TEXASSPEED 1 7/8 headers ls6 intake.procharged 6 psi 491hp 471tq wheel
Seen lots of comparing of cams and we went with BTR stg4 as many ZL1/LSA motors and their builders seem to love them... might lose some grunt down low though if these results are typical. We added a CircleD 3600 stall converter. Went Wiseco/K1 lower end that BTR had. Tooley seems to have attention to detail and a loyal following so we bought from them. We haven't got the car back yet so we shall see if the desired results occur. Update: Went with a Hughes 3600 stall, bore & stroke, 12# boost = 700+ whp/ 690 tq snapped the 456 input shaft rebuilt with CircleD 1200hp kit.
and my buddies wonder why I left the 5.3 in my '99 GMC Sierra stock. Those cams would suck hauling my boat down the interstate @ 70 mph. I also use it to haul my cars to the track. A stock '99 5.3 can pull a '66 Chevy II and "87 Monte Carlo SS or '95 Vette with no problem.
That new BTR, Truck Norris Cam looks promising
Instead of knowing I'll "need a converter", I'd really like some insight on how big of a converter, when to buy a bigger one and how to match it. I have a stock 4.8. I'm getting advice all over the place from 1800 to 3500, to whatever your peak torque is, which on that engine is about 4000. And those variations in number are from "professionals" or at least trans builders, racers, performance parts sellers and performance magazine editors. And theyre all talking about street engines. How do I pich a converter for a street 4.8 ls that will eventually have a mild cam like a stage 1 or 2, without having to change the converter again? I had finally settled on 2400. Again, not racing. Mainly street with a bit of performance.
BTW, great videos. Its helping me figure out what I want to go with on a cam, etc. New to the ls world.
you will be happy with a stage 1 cam and 2400 stall on a 4.8l
@@richardholdener1727 awesome! Thank you, sir!
If there are marine grinds available, that's where my order will be.
They idle clean, pull from idle up, and still have respectable top end.
What better all around cam?
My truck runs 1600-2000 with the cruise set. 98% of the time it's between there and 4000 RPM with only occasional fun runs to 5000. In my opinion, calling cams that don't really add power until after 4500 RPM "Truck cams" is a joke. Are you supposed to manually down shift it and try to run 5000 RPM to actually gain power to pull a trailer? I understand a cam alone won't make tons of low end torque. Help us out please. On a 5.3L, what combination of parts will add torque from 1800- 4500 RPM? If it adds some power above that, it would be nice, but not necessary. I'd like to see a WILD build for this RPM range.
For power and torque in the RPM range your looking for I would suggest a Magnuson supercharger it will make that 5.3 fell like a 6.2
I think my 2007 Buick Rainier 5.3 needs that mild cam and Trailblazer SS intake
So, when I was much younger, I remember seeing trucks listed as having “RV” cams. This led me to believe that they were built for max torque at lower RPM. Are there still cams out there that gain significant torque output? I mean, in real world use, my 2003 2500HD LQ4 truck doesn’t see 5500 RPM for any significant amount of time. I’d love to have a 30-50 lb-ft gain at 3-4500 rpm tapering off to near stock levels at the peak even if it meant minimal to no HP gains on the top of the range. Personally, my truck is for hauling/towing, but I don’t do enough to warrant a diesel (or building a big stroker engine) for the extra off the line lugging ability. Great vid, as always. Thanks Richard!
hard to gain 50 lb-ft down low on an ls application with a cam
@@richardholdener1727 oh, I know, just saying that as an example.
I’d Probably be better off with a “stage 2” PD cam and a LSA anyway.
@@richardholdener1727 can you do 1 on the btr truck Norris cam
Nice! I actually went with the truck style cam in my near stock setup for the local autox (89 Mustang 5.0 Explorer cam) just for the low end grunt of pulling out of corners.
You had a test with a lunati bootlegger cam with 5.3 with a fast intake and Tfs heads 481hp
Gotta love a good bump stick video!!!
Richard, thank you for all your info. A Star is born
How about a cam test for us poor California boys? Maybe you could find cams that increase hp and still pass smog.
Seconded
On a heavy vehicle you won't want to lose much tork down low and forget top end on a truck past 75 mph.
54-469-11 cam I’d love to see on a vid for a comparison to the 54-454-11
I have directly compared those cams-on cath and rec port heads
@@richardholdener1727 I’d love to see your findings on that if there isent already a vid

Would definitely like to see some testing on Truck Norris. Great video as always. ✌😁
Please do the Truck Norris cam! Wanting to know if it’s worth it.
IT IS
I was kind of wanting to see the BTR stage 4 truck cam, but it was definitely enough info to show me what it would be. My buddy has a really nice, billet face "2500" stall converter for sale for cheap, but I've realized that it's not going to work well for me.
Triple disc or nothing. For a stage 4, 3200 minimum in my opinion. Personally I'm running a stage 4 on a 4k and it's nuts from a dig
@@swappedoutZ71 That's pretty much exactly what I have decided on. Fortunately, I didn't buy the one off of my buddy, and have the money to get a proper one.
Hey Richard, going by with your comment, it’s okay to put stage 3 cam truck cam for my TBSS? Stock converter and she is a daily and not a race truck. I do some hauling with it for DIY house work. I want more power but I don’t need it to spin the motor to the moon.
stage 3 truck is not good with stock converter-try a smaller cam
I guess People that would enjoy pieces missing from a puzzle box would be the ones that wouldn't stick around till the end of your videos , thanks for all your great information Richard .
Great work. I'm building a 6.0 with ported 706 heads and planning on using the comp in the video. Would love to see a similar video on different cams with a higher compression 6.0!
What will you be doing with the truck?
@@swappedoutZ71 it's actually going into my 1958 Edsel, it dropped a valve a couple months ago so I mounted an lq4 and 4l80 in it and planning on building both this winter and eventually plan on putting a lsa blower on it but that's a few years down the road!
@@rb002680 well don't waste money in ported 706s if you don't have them already, get the rec port truck heads or something.
Asking because I ran 706s on a 6.0 and while it was a torque monster it lacked up top. But I was on unported heads and stock intake. I now have ported 243s and ported tbss manifold. It's still a torque monster, and faster up top now too lol
@@swappedoutZ71 that was my plan originally but I'm also planning on selling my daily and replacing it with a 2010+ silverado so figured when I go supercharged I'll put the 706 heads on the truck to increase compression and low end torque and put the rec port heads on the edsel
@@rb002680 sounds like a well thought out plan to me lol. Get bigger valves in the 706s. The 6.0 will love those heads
How about a show to demonstrate how to go from stock truck manifold to TBSS.
that just bolts on

Thanks Richard. I'll check again for the later Torque cam test.
Camshaft decision time again ? Geez man, I just don’t know. Let me get back to you later on that. I’ll have to get an LS first before proceeding with cam choices
I do have a nice inventory of Cleveland solid roller cams...🏁
those work too
@@richardholdener1727 ....for sure. And if a physical fitment issue should pop up, I have a big hammer that’s perfect for fine tuning as needed 😱.
All cams are performance cams if it gives what you want.
So this is with stock valves only spring kit? Also no valve seating just swapping cams and running it with just mandatory checks correct? Also love the content. Always a lotta fun and I learn stuff.
stock valves-only cam and springs
What about bone stock junkyard engine with stock manifolds, ignition, intake, and fuel system? How about a test for us not wanting to do a rebuild, Holley engine management, intake, or headers, just a cam swap in our daily driven truck. Would like to see what a bone stock system would do with a couple different cams. I'm not a programmer and still new to LS engines.
it would need to be tuned if you add a cam (even with stock ecu), I just show you what you get if you tune it properly with a stock ecu
@@richardholdener1727
OK, so no matter what, there's no drop in cam to use? The BTR NSR cams advertise no springs, tune, or converter. Or they used to. Just wanting a little more out of my stock 285,000 mile daily pickup without the huge investment.
Those are the V1 version on the BTR truck cams. The V2 version is what is available now and has a bit different specs. I have the BTR stage 1 truck cam V2 version. It is 206-212 *.553* lift and 112°. V1 was .525 lift.. a small difference I know but would like to see if any difference between V1 and V2

Id definitely love to see you test the Truck Norris cam! I just ordered a L96 and plan on boring it 30 over with DSS 6cc dome pistons, LPE Ported 823s with Stainless Hollow Stem Intake Valves and stock Inconel exhaust valves, ported Gen4 rec port truck intake manifold and 92mm throttle body. I am definitely leaning towards the truck norris, this combination will be going into 2009 GMC Canyon crew cab with a Supermatic 6l80e swap and probably a 2400 stall converter! I also have the rear axle from a Hummer H3 with 4.56 gears and currently running 32" tall tires

BTR LS TRUCK NORRIS CAM vs the original tourqe cam wonder how they truly compare
the Norris cam is suppose to be better everywhere
Hey Richard, need some help please. I have put an Ls1 in my 94 GMC Sierra. Here in New Zealand the iron blocks are hard to source, my question is: I want to do a Truck Norris Cam but have been told that a performance cam would be better because I have a 'Street engine' in, not a Truck iron block. Am I wrong to still look at wanting the Truck Norris for the ls1?
how much power do you want
The tuners here steer clear of this Cam as they struggle to tune it or to find the tune file for it, is that correct also? I don't see why this would be a hard Cam to tune even if we were in New Zealand.
Can somebody please give me a part number for the springs for the comp csm
A 5000+ truck or SUV with a stock torque converter stage 1 if your willing to put a 2500-2800 stall converter stage 2 anything bigger than a stage 2 in a 5000 pound truck or SUV will need a even higher stall converter 3000+ and lower gears
Great vid. How do you decide what torque converter to run with an upgraded cam? (stall)
ASK THE CONVERTER COMPANY-OR CHECK ON LINE WITH ANY OF THE LS CROWD
Budget drag racing build… biggest cam the 5.3 can run and a single plane carb… if you are taking requests 😂I say carb because they are cheap and a lot of guys making the cross over to the dark side A. Don’t wanna learn fuel injection because it’s new/scary/complicated ect…. B. Already have more than one holley laying around anyway C. Because of B it’s a cheaper route to go. And D don’t wanna do a turbo build yet because of new/scary/complicated… you get the idea. Oh and spoiler alert I’m one of those guys 🙄
Built carb motor on nitrous type of guy 😂🤣 that’s still a good setup but I think turbo and computer tuning will give you more power on the big end, but I get it sometimes this stuff gets complicated and rather not mess with but it’s worth it
@@geraldjackson263 I agree with you completely. I always seen the carb N/A route to be a more do it yourself friendly approach.

thanks,
please watch how to max your 6.0l video
Can you please make a vid explaining about max piston speed, 400 is a number I read a lot ., But what if you want to ref it a bit more? what you need, for a 4 inch stroke 6000rpm is about the max if I see othet ( not verry clear ) vids, But I have forged , crank pistons, H beam rods . 4 bold mains . Is that good for a (bit) more ?
don't be concerned about max piston speed, it's not relevant to your motor
Would Stage 2 be a better shot than stage 1 for a 6.0 on a 2500 Suburban? Stock exhaust.
Great video. Thank you very much.
Hello. Thanks for the videos. I wanted to ask can a LS engine have good oil pressure with a new oil pump and also have a rod knock?
yes
Duration is a product of volume. Stock engines do better small mild duration. Cubic inches or higher rpm benefits from long duration camshafts. Vehicle weight does come into play.as does bearing clearance go hand in hand
I just swapped one performance cam for a bigger one 226/228, 585/588 @114 to a 238/244, 595/595 @114. After tuning the bigger cam only picked up 3.5 hp and at about 400 rpm higher, and lost 20-30 through the rest of the rpm range. Different dynos but both dyno jet. Is it possible that the bigger cam only gained 3.5 hp up top and lost EVERYWHERE else?
those two cams should be 20+ hp difference
Good power for stock headed 5.3... I run a btr stage 2 with 2600 stall and heads. Its nasty all the way through the rpm range and perfect for a daily. Can you test the ls power max plus cam? It looks like a good camshaft for a 5.3 with the 220/222 duration and good lift... your thoughts?
I have a 2001 Silverado with stock 5.3 and tune and am going to go with the btr stage 2 cam mainly because
I plan on one day putting a 6.0 in it and can use the stage 2 cam in it when I swap it in. Otherwise I would just
go with the stage 1 cam. Oh, and I built my 4L60e trans with all the upgrades and also put the trailblazer 4.2
torque converter in it which gives me about 2600 stall or so behind this little 5.3 motor. The extra stall makes
a pretty big difference on these motors for sure. Mine is a 4x4 that I tow with so not wanting to go too
crazy on stall or cam. For now, just going to the stage 2 cam with springs and maybe a tbss intake if I
can find a used one for the right price.
the 220 cam works-it will just be softer down low than the stock cam
Can you do same stock 5.3 test with summit racing stage1 2 3 4 cams ??
Just look at the specs he gives out for these BTR cams; Duration, Lift and LSA(lobe seperation angle)
Compare the BTR stage cams spec on this video to the SR cams and you'll have an idea of what the HP those summit racing makes.
Usually stages on racing parts are just dumbed down ways of telling one part is "better" than the other. Im a dumby myself and could be wrong about this but, i try.😅
Do you have a dyno of a 6.0l lq9 or ly6 with ported 706 heads ss2 cam and lsxr intake comparison?
no-only with stock 706 heads
Great video! Have you done any testing on the Gen IV 6.2 with variable valve timing? Like out of a 2010 and later Escalade.
Not yet! no vvt gen 4

And then some boost! 😁
boost any of these curves
Why no love for the BTR Torque cam?
