Interesting! BTR has obviously done their homework optimizing the Hot Rod cam. The SS2 never had enough exhaust duration, in my opinion, because of the relatively small exhaust valve in many LS heads. I guess this supports that feeling a bit. Good job BTR, and Richard thanks for showing us!
Ahhh, I love hearing engines roar again on Richard's videos. It seems like it's been a long dry spell. My guess for the secret sauce in the new Hot Rod cam is narrower lobe displacement angle and longer exhaust duration than the SS2.
If I had to guess, the HotRod makes more top end power than the SS2 thanks to a combination of wider LSA, more lift, and a “better” lobe design that opens the valve quicker. The bigger SS2 cam may make similar power at lower rpm because of the narrower LSA and the less aggressive lobe ramps may make it act like a smaller cam in comparison to some degree. It may have more duration at 0.050”, but may have less duration at 0.200” and beyond. I’m by no means an expert. This is just a hypothesis.
Can you please do a Texas speed torquer series camshaft comparison? 4 cams to compare. Would be good content! BTW I love your content. Keep up the good work sir
The Norris can has that mild lobe profile and that tight LSA perfect for low end torque I haven't seen the rest of it but I'm a fan of that cam I hope to see something even better
Truck Norris vs summit racings big truck torkinator vs Texas speeds chopacabra? It seems like everyone is coming out with their own version of the truck Norris now
With the price difference between the ss2 and the hot rod cam it seems like a tough sell it doesn't pick up anything down low and you would need bigger springs than you can get away with on the ss2 and I have heard that more lift is hard on the valve train components
Just installed a Truck Norris in my 6.2 sierra. Pretty happy with the results. Deleted the vvt. I lost some power down low, cruising around 45-55mph with torque converter locked. Could be from my amateur tune…. Also down from 14.8 mpg to 13.5 could be from a heavy foot though..
@@HandMadeRoyalty it sounds pretty damn good. Has a nice chop and aggressive idle. I have my tune dialed in a lot better. I think my issue now is injection timing. Not a lot of info available online.. I wish BTR would give a complete cam card. Would help a lot with dialing in the tune…
@@HandMadeRoyalty - if you are not worried about losing Low end power, go with the hot rod cam! I drive my truck to work a few days a week, I didn’t want to lose too much drivability and gas mileage.
Would love to see you do a tech/dyno video comparing the stock valve train against the BTR shaft mount rockers with hydraulic lifters and BTR shaft rocker with solid lifters all on a popular cam.
@@richardholdener1727 The guys there at Westech compared hydraulic lifters and solid lifters on the same hydraulic cam. Curious to see what kind of gains can be made on the LS platform from just improving the valvetrain alone.
The SS2 cam is much cheaper than the BTR Hotrod cam. Besides the 5-10hp on top, are there other advantages to the shorter duration cam? Manifold vacuum? fuel mileage? I was hoping to see an improvement in hp and torque over the outdated SS2.
On a dyno, you only see WOT. The smaller cam will idle better, provide better low speed torque production at all throttle imput, and wear your valvetrain less.
I'd like to see that hot rod cam with some work done on the cylinder heads and a little better intake manifold/throttle body. I bet 500 would be an easily achievable number with that camshaft.
That hotrod cam is definitely an interesting cam way less intake duration but more power than the ss2. Should be a much more fuel effecient cam and be a way more driveable cam compared too the sloppy stage 2, it's almost like a truck Norris stage 2 or stage 3/4 truck cam replacement
We need tests on compression and the truck norris camshaft no one ever talks about that will 10.5 to 1 help Amp hp on a 5.3 or does it hurt the torque? I don't know sounds like an easy 50k clicks to me
I still think Truck Norris for the win unless you are building an absolute high rpm only setup........maybe a manual trans road racing deal? The TN doesn't seem to fall off too much at the absolute top but still adds a ton down low. I have no doubts about running the TN in my 6.0s in my 2500 truck and 2500 suburban. A cam swap and tune is on the shortlist for sure.

Hi Richard, never "built up" in the past and I'm thinking about the TN cam for my 2005 Yukon. It's not just a daily driver, but one we'll use for trips pulling our trailer with motorcycles (about 3500 Lbs). How would the TN work without headers? Would MPG suffer much?
lot of comments on how dated the ss2 is , getting on there for sure , but it's not a fashion statement , just goes to show that good engineering back then still good engineering today . is there a hate out there for the budget cam that is a lot better than it should be ? tech and design should always get better with time , but im guessing the old sloppy stage 2 is gunna have a better /longer valve spring life , the truck norris even more so . how about finding the biggest full lift and duration cam that you can get into that 5.3 under the existing rockers and compare . or maybe you have already richard ?

I have a 03 Tahoe with a 5.3, I want more bottom end for hills and towing. I don’t like pulling hills at 6k and would like more bottom to middle power. What cam do you recommend? Or do they make a bigger ratio rocker to give more lift without sacrificing duration?
Honestly there are only two ways to gain low RPM torque with your combo: 1. Remove the heads, mill them for higher compression, shorter pushrods etc. High compression ratio will help the low end a lot, but high octane fuel and a tune is needed. 2. Speed engineering long tube headers (any work but these are low cost and awesome stainless). The scavenging effect of long tube headers helps big time when towing and low RPM. They help all across the RPM range but I really notice the gains when towing or up hills at low RPM. Plus no tune needed. Then use moderate sized exhaust after the headers to give you some back pressure. Back pressure isn’t needed for Max HP however it will help part throttle response and fuel mileage when properly sized. For my stock 5.3 in a lifted Yukon with 35s I run 1-3/4” speed engineering headers with true dual 2.25 no x pipes. Sounds great, magnaflow mufflers. It’s a lifted truck so I prefer the low end gain from headers vs a cam. Then I scored a 6.0 LQ4 for less than a cam would cost so I’m swapping that in once I do gaskets. Adding cubic inches is the third way to gain low RPM torque, I’m just using the computer from the 6.0 truck so no need fir a tune really. On my 2012 crew cab with 6.0 I run the same 1-3/4 headers, Remflex gaskets never leak, dual 2.5” with magnaflow and it’s also great. I did a tune on this one which also helped. A cam just isn’t worth the $ compared to exhaust for my lifted trucks that spend very little time over 5000 RPM. This one Tow’s awesome now it can haul my car on a trailer in 6th gear on flats without lugging. Before the headers and tune it was a dog.
@@TwinTurboSkylark I heard the stock exhaust manifolds flow pretty good and long tube headers are only a few hp increase and that’s up top. I can’t imagine having 35s with stock gears and towing a car trailer. But then again I live in Northern California by Tahoe and Yosemite where we really have hills and 10,000 foot passes. Some states like Texas consider a over pass a hill. Your truck is also newer with the l33 that makes like 50 more hp too. I also think that a Tahoe weighs a 1000 more pounds than a truck.
you could spend that money to only gain power in the higher rpms. or go ahead and plan for boost. the right size turbo on a stock engine with injectors makes a world of difference for towing. keeps the rpms low and almost no need for downshifting at all unless you have tall tires and high gears. I've done several cam swaps and engine builds. nothing beats boost.
@@richardholdener1727 ok. So in reality it's a 1 5/8" size pipe inside(assuming .60 ish wall).I was searching a video for some header building tips. And found an old hot rod video explaining a formula for peak torque rpm depending on primary size(by area) so if you go by the mfg size of 1 3/4 they you will be off in calculations. Thier example of a 350 was somewhere in the area of a 400rpm increase in peak torque rpm with a 1 3/4 over a 1 5/8(actual ID) I would love to see you do some testing on their mathematical equations too!!
@@richardholdener1727 I'm middle aged and my elderly father said "ah f,ck it, life is short just spray it with nitrous" But I'd like to do it all NA first and then think about spray or boost. I just need to figure out the right combination of cam, intake, converter with 4.30 gears. And of course valve springs, rockers or just new heads.
@@DM-qp7do If it were me I would look for a 2007 5.3 with 243 or 799 heads and start from there It should have flat pistons, better rods , great performance heads Then think about the camshaft DD or weekend cruiser ? High lift .585/.600 more hp but less valve train life .551 lift great for DD and long valve train life The 05 5.3 should have beefier piston rods and you could get flat pistons and the 243 heads and it would work awesome for boost too
Richard, it's sometimes hard to follow your graphs. You do a great job, no complaints on that. But it would be nice to see the actual numbers on the cams at the end. All on the same page, like this: A=450hp/460ft/lbs B=435hp/475ft/lbs etc., etc. Anyway, great work.
All the cam shit is confusing. The hot rod specs you showed on the box says different intake lift than their website. Also the V2 stuff shares the same exact cam. The specs you show for hot rod are the same as BTR stage 1 for NA same as BTR PDS stage 1 v2, same as the BTR centrifugal stage 1 v2. I thought all those different applications had different specs. Maybe they were different when it was V1 (1st version)
@@richardholdener1727 yeah I understand that, especially after seeing so many of your videos. My hangup is, I could swear in the past, I had read that positive displacement, supercharger cams sacrifice a little bit of the very abundant low and torque, and shift it up towards the higher part of the rev range . And then a centrifugal would be the opposite. They somewhat lack as much bottom and torque, so the cams are spec'd as to add low end torque while sacrificing a little at the top. I guess maybe things have just changed because it's kind of a solved thing or I just totally made all of that up in my head. Thank you for all your hard work.
Do you expect to see in the near future a cam that will produce Truck Norris torque down low with higher than Truck Norris horsepower up high? I'm building an LQ4 if that impacts the response.
11 horsepower is more but l bet it's not really nothing your going to feel in the seat of your pants if it was 25-30 then yes and your only getting the 11 way up top of the powerband
This is not new. The last prefer high lift short duration. There’s been a few companies that make only high lift cams. .550 lift is a small cam for an ls in my eyes but you look at duration, being a dummy I studied the dyno sections first before reading the tech stuff. On performance trucks the trend was high lift short duration if you wanted to make power.
That is the smoothest cam install I have ever seen, even sped up, Richard is the Lock Picking Lawyer of camshaft installation.
I doubt many guys around do as many cam swaps as Richard. He does a great job of taking the hassle out of cam selection for us that’s fo sho.

Your truck is also newer with the l33 that makes like 50 more hp too. I also think that a Tahoe weighs a 1000 more pounds than a truck.
you could spend that money to only gain power in the higher rpms. or go ahead and plan for boost. the right size turbo on a stock engine with injectors makes a world of difference for towing. keeps the rpms low and almost no need for downshifting at all unless you have tall tires and high gears.
I've done several cam swaps and engine builds. nothing beats boost.
@@nocturnalspecialties642 I agree 100%. It’s just the price is out of my reach
Do people run these truck cams in street cars?
yes-truck cam doesn't mean anything
What was you timing at WOT
29 at hp peak
I've asked this before and did a little research and still don't get a clear answer. When you say inch and 3/4 headers are you talking OD or id?
od
@@richardholdener1727 ok. So in reality it's a 1 5/8" size pipe inside(assuming .60 ish wall).I was searching a video for some header building tips. And found an old hot rod video explaining a formula for peak torque rpm depending on primary size(by area) so if you go by the mfg size of 1 3/4 they you will be off in calculations. Thier example of a 350 was somewhere in the area of a 400rpm increase in peak torque rpm with a 1 3/4 over a 1 5/8(actual ID) I would love to see you do some testing on their mathematical equations too!!
I wish you would dyno test gpi cams, try a new company lol.
I have a L59 5.3 and want to make about 400 to 450 whp, these videos are super helpful 👍🇺🇲
use boost
@@richardholdener1727 I'm middle aged and my elderly father said "ah f,ck it, life is short just spray it with nitrous" But I'd like to do it all NA first and then think about spray or boost. I just need to figure out the right combination of cam, intake, converter with 4.30 gears. And of course valve springs, rockers or just new heads.
@@DM-qp7do 450 whp is a stretch, but not hard to do at the crank....?
@@trailerparkcryptoking5213 yah he would need a rec port stroker for 450whp NA.
@@DM-qp7do
If it were me
I would look for a 2007 5.3 with 243 or 799 heads and start from there
It should have flat pistons, better rods , great performance heads
Then think about the camshaft
DD or weekend cruiser ?
High lift .585/.600 more hp but less valve train life
.551 lift great for DD and long valve train life
The 05 5.3 should have beefier piston rods and you could get flat pistons and the 243 heads and it would work awesome for boost too
Test don't guess! Cheers!
Richard, it's sometimes hard to follow your graphs. You do a great job, no complaints on that. But it would be nice to see the actual numbers on the cams at the end. All on the same page, like this:
A=450hp/460ft/lbs
B=435hp/475ft/lbs
etc., etc. Anyway, great work.
GRAPHS ARE BETTER THAN RAW NUMBERS
Should put the best cam in the mix
THAT VID IS UP
Is it whp or overall hp?
engine dyno hp
A lot of LS guys are running GPI cams, why don't you ever use their cams for your comparison videos?
WHO ARE THESE "LOTS" OF GUYS? THEIR STUFF WORKS WELL
lol well maybe because ( those gpi) guys ant give my buddy a cut $ lol
How does the ss2 do out past 6500? I’ve got a 4.8 ss2 with a vs78-75 I’m hoping to spin 72-7500rpms.
2600lb mustang street car.
Should peak power at 7500rpms with a ss2 with the right intake manifold
SS2 is too big for a 4.8 if you want good response on the street.
7500 rpm power peak with a ss2 (even with a short runner intake)?
Agreed, go smaller on the cam and shoot for a 6500-7000 peak and gain reliability vs 7500+
Right on appreciate the input, and the videos!
I can only deduce that the increased lift made up for the smaller duration
Also, looking closer, the Hot Rod cam has overlap like a "true" 109.5 LSA. The Truck Norris cam is about a "true" 107 LSA.
Are all these cams stock converter friendly?
Even stock cams aren’t “stock converter friendly” lol
only the Truck Norris and only on a 5.3l and above
BTR's camz've gotta be blood magick or somethin', dude.
Mmm I might just have to pull my btr stage 2 truck cam out of my 6.0
Thinking the same, have same setup. Going turbo later. Norris cam looks nice
All the cam shit is confusing. The hot rod specs you showed on the box says different intake lift than their website. Also the V2 stuff shares the same exact cam. The specs you show for hot rod are the same as BTR stage 1 for NA same as BTR PDS stage 1 v2, same as the BTR centrifugal stage 1 v2. I thought all those different applications had different specs. Maybe they were different when it was V1 (1st version)
they apply the same cam to many applications because it works on many applications
@@richardholdener1727 yeah I understand that, especially after seeing so many of your videos. My hangup is, I could swear in the past, I had read that positive displacement, supercharger cams sacrifice a little bit of the very abundant low and torque, and shift it up towards the higher part of the rev range . And then a centrifugal would be the opposite. They somewhat lack as much bottom and torque, so the cams are spec'd as to add low end torque while sacrificing a little at the top. I guess maybe things have just changed because it's kind of a solved thing or I just totally made all of that up in my head. Thank you for all your hard work.
Do you expect to see in the near future a cam that will produce Truck Norris torque down low with higher than Truck Norris horsepower up high? I'm building an LQ4 if that impacts the response.
A vvt cam could do it. Easily.
@@trdscfjc lq4 isn't a vvt motor though
The only way was already mentioned. Vvt... my question is vvt viable with the truck Norris.
It doesn't matter an lq4 "isn't vvt", it can be added.
vvt adjustability is limited with larger cam profiles
11 horsepower is more but l bet it's not really nothing your going to feel in the seat of your pants if it was 25-30 then yes and your only getting the 11 way up top of the powerband
Richard. The whole idea of a cam is the idle. We want to hear what they sound like at idle. Power is nice too, but what does the idle sound like?
the whole idea of a cam is NOT idle-it's power-but if you wanted idle-that was in the dyno run clip
@@richardholdener1727 oh yeah, I guess it is about power. I just love a choppy hot rod idle.
This is not new. The last prefer high lift short duration. There’s been a few companies that make only high lift cams. .550 lift is a small cam for an ls in my eyes but you look at duration, being a dummy I studied the dyno sections first before reading the tech stuff. On performance trucks the trend was high lift short duration if you wanted to make power.
LOTS MORE TO IT THAN THAT
👍💪
So you ran out of golf tees and sacrificed a screwdriver? 😂
I saw that but it's not real sacrificed once it's off the dyno he gets it back
it wasn't even my screwdriver! #winning
OMG, you didn't use a front cover alignment tool when putting it back on. It will destroy humanity! Oh the horror!!!!
we aligned it with the damper (I mean alignment tool)
@@richardholdener1727 The seal knows! Like cast pistons shatter when you unbox the turbo!
And the best cam fell of the face of the earth?
THAT VID IS UP
Personally I blame squirrels
🐿🐿🐿🐿🐿🐿
Thats alot of squirrel
Thank The Lord for answering my question love you richard
