Rich is putting in the work for us so we don’t have to. We owe this man 2 subs. Thanks Richard!

Love seeing TSP cams finally here.

This is why I absolutely love Richard!! Best job on the planet 🙌🏼

Pretty much confirms what I felt it would make, and makes my combo make sense now. Time for me to change cam and cylinder heads.

Great work as always Richard!

It's great to see the Lil Loper in this test. I have it to go in a LQ9 with similar suppting mods .

I just can't wait to get one of these motors in my garage before next winter. I will be studying Richard carefully. I need to be as confident. Thank goodness for you tube university.

Richard holdner thank you for all of the golden knowledge you provide. You sir are a motor legend.

This is what I've been waiting for . Similar cams from different cam companies . Keep up the good work 👍

Impressive that a junkyard 5.3L can make nearly 450hp and well over 400lb-ft with just a good cam.

I like cam motions grinds... I run a titan 2 ls1 cam in my 5.3 and it has power everywhere and a monster up top. Mated with a 3200 stall in a 3500lb silverado it's a fun little street truck. The main thing I like about CM is that they don't slam the valves shut and not a lot of people run them.... everyone does a truck Norris or texas speed etc... never anything different. On the btr I have in my other truck valvetrain noise is a little louder but it runs great as well. Everyone has their preference, good thing there are a million choices.

Hell yea iv bin waiting for this I got the chopacobra last year at ls fest for my truck and love it

Impressive work like usual

I have a C10 with a LM7, LQ4 cam, LS6 springs, air gap, 600 carb, 4.10 gears, it has no problem spinning the tires as is, I’m sure any of these cams would be a considerable improvement…

Looking forward to seeing some testing of the TSP Honey Badger cam. Only reason I haven't cammed my CTSV LSA setup is because I really want something with near stock idle quality and without the low rpm losses of the LS9 cam. I've now tested 2 Honey Badger setups in recent weeks and with an idle speed of 750 rpm or so they sound almost stock. TSP claims about 50-60 hp on a bolt-ons LSA setup at 13 psi and similar gains on an NA setup too. Both the LSA setups I tested were pushing 750-800 whp on ported stock blowers on E85 which is pretty nice while retaining stock idle quality. If the cam gets the Holdener seal of approval in a head to head test I may just buy one.

I like them all. Thank you Richard.

Yep. High oil pressure is high drag .

I absolutely love all the comparo vids, I'd really like to see an ls with a carb type intake and a shootout with aces, jegs, fitech, holly and whatever other tbi you can get your hands on. There's some of us want the LS power but that carb like look in our classic cars

Thanks Rich VERY VERY VERY good video.

You can also spin the cam to push the lifters up and use 5/16 (NOT 1/4) wooden or aluminum dowels in the 2 holes that the cam retainer plate cover to keep the lifters from falling down into the pan.

What a great sound. Good ol LS rumble

Richard is there a way to get a good audio of the idle sounds when you redo the test? I know exhaust makes a big difference in overall sound but I'm wondering what the cams sound like at idle to make a comparison.

Puting the finishing touches on the car and getting ready for some racing.

It'd be interesting to see the vacuum pulled down with each cam. I'd probably go with the Summit cam just based off of the specs. It looks like it would have the smoothest idle.

This is perfect timing. I was just looking into a cam for my turbo 5.3l I think I originally went too big with my 226/230 .600/.575 113+4 cam. Might step down to a stage 1 since it's my DD

Thanks for your videos I’ma build me a 5.3 with some of the parts you recommended for the 500hp

I was hoping to hear which one sounded the best? I figured they would all be pretty equal in power.

Gotta luv the guys that hate on LS engines because they are so simple - powerful - reliable - plentiful - and low cost ! Nuff said ! 😻

Kewl test I have that summit cam. In a lq4 in 94 s10 terminator x max running everything

Interesting how the nearly. 050 lift difference on the first two made little to no difference. Focus on the duration and split for your targeted rpm range?

Thanks Richard!

Thank you for the intense info you put out for us motor heads it’s second to none ! I’m building a 5.3 for a 1989 Suburban 2500 TH400 . I live at 7500’ elevation , what would be my best choice for a cam that makes torque ? I’m wanting drivability, Holley terminator harness computer stock lower end LM3 . Thank You so much ❤

I wasn't expecting the power and torque numbers to be so close. I'm guessing that they should still be pretty close even once the oil pressure is resolved

Perfect timing. Trying to choose between the btr and tsp. Now to the video. Lol

We need a coil pack comparison . truck vs car vs LS3 ,msd .....etc

As many cams as you install I would think you would use a split timing cover.

I like the chopacabra for the idle but to know I’m not sacrificing power for something so vane makes me feel better😂

Surprised how close the outputs of some of the cams when the specs were different. Very interesting to me.

Hey Richard love your videos, I install dozens of these truck cams a year, everybody wants these cams and I see similar results on the chassis dyno. What I hate about the truck norris or tsp cam is that they advertise "no stall required" but they end up with "no balls" till 25/2600. They are awsome with a 26-2800 stall. So 2 things I'd love to see, 1: a test advancing the cam 2 or 4 degrees 2: test with a set of "variable duration lifters". Howards cams advertises up to 10 degrees of duration lost below 3k rpm, more intake vacuum, more low speed torque. Could either of these bring out some bottom end? Just a video I'd love to see.

In the end out of all the cams run the cheapest or company you like best.

How about the melling mtc-7 and 8 cams? I know the 7 is on the mild side but haven’t seems much info on it.

I have that summit torque cam in a flat top 6.0 with 243 heads and 1-7/8 headers in a crew cab 2500hd 4x4 and I really like it.

You should take a sound clip of each cam at idle since they all claim some sort of choppy idle.

Got the btr stage 1 but was thinking about switching to truck Norris but might just get chopacabra instead because of the price

I've put the Summit 8709R1 in my stroked LQ4. Can't say how it is yet, engine is not completed yet

Enjoyed! Thanks

Would’ve really liked to see a GPI cam, such as their SS3

time sert will fix those threads really nicely

Why don’t you do a comparison to all the summit pro cams?

So 11hp and 8 lb ft more than posted on the BTR site. I think it’s safe to say that’s the Fast intake over the TBSS. I like seeing that the manufacturer isn’t inflating numbers.

Would like to see how the Scoggin Dicky Ls6 plus compare to these as well

Cammotion should send you a little chopper cam as well. Have one in my OBS with the 5.3. Made 318 rwhp on 87, random trash tune, clutch fan through a not happy 3 speed auto with a loose converter

Can you chuck in the lunati 219/223 cam next time too?

On the retest we need to see all 4 on the same chart lol please and can you find a cam checker to get exact specs lol rumors

Richard, When you're saying that the high oil pressure was pushing out the retainer plate, Could that let the lobes move fore/aft, damaging a lifter or wiping a lobe eventually? Also, what about tapping the oil holes in the block and running braided line in between? cutting the retainer 9-3 below those two holes I'm not sure how much room there would be between the cam gear and the braided line(?) Would 1/4"/AN-4 be enough?

Test the BFD Chop Monster cam please 😁

Thanks for all your work. I recently check a truck norris cam on a ls in the shop. I keep comming up with 109 LSA and not the 107.5 LSA on the cam card. For a truck cam I would like to see what a single pattern cam of around 219 @ .050 and .525 - .550 lift with a true 107 - 108 LSA would do on the LS truck engine. The single pattern cams and tight LSA always did well for me on short track racing years ago.

If anyone is wondering about the Truck Norris cam specs Delta Cam put it on their cam doctor and showed the result on their channel.

I think alot of people will go out and buy a big cam and be disappointed by not matching the combo. Rich needs to make that point. I mean a stock 1800 rpm stall converter with a cam made for a 3400 stall converter will suck. Bv

All of the new test used to be different colors, what happened to the software?

I have the summit cam and it does ok. Should have gone a little bigger though since I did a 4in stroke. fairly smooth idle I suppose because of the extra stroke. I will say though considering the oil pressure vs test results, looks like the truck norris will ba a little better then the summit one by a few hp but not much. I don't see 20psi dropping more then 5-6 hp.

What Cam sounds the best with a single s475 turbo setup?

Just curious 🤔 when are you planning on doing another comparison between the Chopacabra and the TN cam? That's what im waiting on before I buy one for my O4' Yukon. Thanks man you're doing a kick-ass job. And I appreciate all you're hard work.

Just port over the cams from the xe sbc line and get a great custom cam assuming you can pick the correct one 4 your combo. Bloodviking

Comp cams just came out with a new line of truck cams too. Looking pretty aggressive for a supposed stock convertor friendly can

They all have a special purpose!

It seems around 108 LSA is the sweet spot for LS engines. It also seems lift doesn't matter too much for LS engines. At what power level and/ or displacement is valve lift more of a consideration?

I've had 2 cams from cammotion fail. Lobes falling apart?

I would love to see a test on the BFD chop monster cam there’s nothing out there also do you think lower oil pressure hurt the power output?

Texas speed cams can go bad if you open them and leave them out for months before installing. If you need to open them up make sure to refrigerate the cam after opening

You did the Truck Norris vs the NSR cam on the 5.3 with no noticeable change. You also did the same grind with different LSA. I’d love to see an engine run with the same grind other than lift to see where the plateau is, if any.

Can we all agree that this man should now slide into Betty White’s recently vacated spot as the nations most valued treasure and should be protected at all costs 😂

Have you done the madmax cam shaft from tsp? Been trying to see numbers on that cam

Any downside to daily driving a cammed out 6.2 truck?

Hell yeah 🤘🏻

5:18 On the Gen 4 motors, you can stick a 1/4" diameter wooden dowel down the block, on both sides, in those holes under the cam plate once you've rotated the cam and pushed all the lifters up in the trays. The dowel will then be sitting under the lifters and will prevent them from falling into the oil pan if they work loose because of worn out trays. You may have to rotate the cam a touch to get the dowels all the way in. I.I.RC., a 16" long dowel will reach all the way back to the rear lifters, and you'll have enough room to get them in with the engine in the vehicle, with the rad out. I do this on every single one, just in case. Call me paranoid, but I like to ensure that I won't ever have to be pulling the oil pan for a cam change.

I don't think many realize just how much goes into making a can test video. Your amazing and thank you. Btw how would the ss2 can compare to these cams?

Hi Richard, I appreciate your videos! Just curious, have you ever had any issues with the stock harmonic balancer used in your videos? Thanks!

Looked like you did a helicoil which works but if it's my stuff and I know about it I just tap it to a bigger size if I can get away with it like I had a striped out exhaust manifold bolt and did that taped it to something SAE so it's a different looking bolt not that hard to notice but u get there are some times when you would not want to do that

Which camshaft has the best name??

I like it a lot

Right on

I have new ls7 lifters and new allegedly oem trays but the lifters don’t hold in the trays when I turn the engine over like you did here. Is this common or do I have more problems I’m unaware of? Thanks

about time you get into who makes the better cam !!!

Richard pulling a little ASMR on us.

Hey I’m looking ones for my gmc canyon v6/3.6 were I can get it ! Or what you recommend me my friend! Thanks

Do you use a stall converter when making these cam videos? Would you make a video explaining what size cam makes need for what size stall? I just bought a junkyard 5.3l lm7 and am currently building it for my 01 firebird…I’m scared to get anything over a stage 2 cam because I don’t want to have a stall converter in a (daily driver) can u also explain what a stall converter does? To my knowledge say you have a 2,200 stall, it would make the converter spin instaid of ur trans/axel up until 2,200 rpm? Is that correct?

Did it five times, know wonder the bolts were striped, lol.

Hi Richard im in the process of buying a set of dart pro 1 ls1 15 degree 225cc heads. Run with the truck norris camshaft, and the ls6 standard intake. Is this to much head vs the 241s My goal is tourqe with some added hp Thank-you Aaron.

I doubt you reply but what cam is the best for chop amd power for 6.0 for frist generation ctsv

If your going for sound with mild lift imo iw the summit. Its so choppy and just sounds nasty. Ive heard in person the chopacabra amd the btr st3 truck cam.

What stall would be the recommended stall on a 5.3 chopacabra with long tubes/ dailey driver, maybe a even a torqestorm sc later

Am building a 5.3 I what can would you recommend to get the most power I want it to sound good to I’ll be putting it on a 2004 extended can Silverado

Still rocking the old 36 tooth Craftsman?!?

Definitely needs a redo

getting ready to order a cam just not sure which one between chopacabra or truck norris, stock converter and a daily driver, looking for power all around. leaning towards the truck norris as of right now. also if i ever have to drop my transmission for any reason i will put in a better torque converter i mean you’re already there why not

As soon as I saw the word chopachabra I know I had to watch.

I feel like the bottleneck has to be displacement with results so similar. None of the other components should be maxed out at this power level.

why 80lb injectors ? whats it actually using at wot ? are 40lb not big enough for this setup ?? im going with chopacabra on an lm7 and id appreciate your input boss 💯

I just found this channel and I heard your name which made me curious. My dad knew a guy once named Richard holder but everyone called him Dick. I think that is a common nickname for Richard. Maybe he is your family tree somewhere. Just found it odd bc we would laugh about the name Dick Holder. Informative video, thanks Edit.... Stupid me. Didn't realize the name of the channel is your name... Anyways my mistake.
