I work 2nd shift and you are 3 hrs behind me so i always miss these live streams. I can't wait till you get your hands on the lt6 flat crank 5.5. Keep up the great work.
Anxiously awaiting the results from "The Best Cam" test. It should be good all around as well. I wish we could get Vizard to make us a LS cam to hang on one of your test mules.
The test we all need to see, is milling the heads in different increments for compression increases on that combo or another. I'm thinking .015 then .025 then .035 and so on. Richard Holdener PLEASE !! Thank You for all you do !
@@sstevocamaro lol, I dont have nearly enough watch time hours, I guess my popular videos are to short lol id be rich with that extra $20 a month though lol
Man somehow I missed the muffler test the first time I watched this episode.This is important because if it’s in a street car it will have an exhaust with mufflers.also good test on 1 3/4 headers.Used to be 1 5/8 was good on 350 sb??Love your testing and analysis of why this is good and not the greatest too!!👍
thank you for bringing up resonense tuning omg... i have an entire LS dream motor on thus sorta logic instead of the typical. i wish people would look at more exotic engineering on these than just Mijolnir for every solution lol
I think a test with polished s/s mufflers will increase hp over the entire rpm range. Polished headers might be beneficial (lol). Just make sure you wear weldng glasses to protect against reflected gamma rays!
Richard. Can u do something for us? I'd like u to test ur knowledge and do some custom grind cams. U have a solid knowledge of cams and the magic that makes them work. It would be really cool if u took like 4 cams (stages) and showed what increasing intake and exhaust duration does. Lsa. Like go crazy wild and mild cams that u can't buy. I think it would be an amazing series.
The "Aussies" have a 1 3/4 Long Tube Header with Y Pipe that Fits around the Transfer Cases n Drive Shafts of the Land Cruiser Frame, Hummmm Helps So Much 👍
Another example of why data cannot be considered absolute. There are a myriad of small differences, either in the combination or the measuring device, that changes the result. Neat stuff
2,000 rpm is the magic number for highway cruise speed for trucks . If it wont grunt its brains out there and mpg its useless !!! The rest is gravy in the powerband when you actually work your truck especially small ls combos .
Unless you have a rare (these days) manual transmission, then no it's not the magic number. Any automatic will unlock the converter well before you start "grunting" to prevent the converter clutch from burning up. If you have a Manual, then carry on but I'd rather just downshift a gear when need to gain ALL that extra power above ~2500rpm shown on the dyno.
@@rancherlee These cam grinders do not get it all . Selling a cam that does nothing at 1500 -2000-2500 rpm then spins past 5500 is a waste of time in a truck used for pulling .
Devin Herrington thanks for the bird dog of that cam , 202 Torque cam . Still i wish it had dyno results lower in the rpm range . To not test for this Richard Holdener is not good when talking truck cams . WE NEED this info !!! This isnt a maybe for most guys with trucks , its a Requirement !!! If i can make night and day differences in a 4.8 off idle torque with a stock engine and tune these gains Are Possible right where a truck needs them . Please Please consider this reality for trucks used as trucks by most guys . You use our junkyard motors so how about something back for us in the deal !!!
My next project is brand new 400 SBC block and 65cc vortec heads, TPI, Mega Squirt ECM, Scoggin/Dickey manifold ( necessary for vortec heads), LS coil packs, 6 inch H beam rod, flat top pistons, Howards hyd roller cam, 4L60E from performa-bilt. Estimated 400 HP/400 LBS/FT. Reference: Purple sage/ 350 chevy should have made. this should be plenty for my ol' square body.
You will make more than 400 ft/lbs if squish is right and cam is optimized for CR and heads. 252/256 with 1.6 rockers on a 107 LCA is what the internet says will rock in a truck 400. 10.5:1 CR

@@williamsmith8062 I helped my brother in law with his '87 sbc by just relaying the information in his books. Camshaft, heads, intake, squish, pistons all from David's testing.
I think what you're trying to say, when you go to a dyno to figure out what your engine wants exactly! Your building a engine program! Which means your trying all kinds of different adjustments, & parts to make the maximum power out of the design & cubic inch you have to deal with! When your making in the 1.4 ish Hp, & TQ, per cube on a basically nothing, engine. your doing things right! 👍🏼👍🏼👍🏼👍🏼Ill have to see the rest later! I just noticed this is old 😳😳😳😳DUH!
My son just bought the cam for his 5.3 swap! Honed polish crank flat tops heads decked valves and springs! It’s going to be a mild N/A engine with rings gapped to later add boost if desired.
As far as I can tell, a turbo just acts like an engine size addition once it spools up. If you have a cam that emphasizes the low end, it will spool up more quickly, but the new power curve will still be (spooled up boost extra power amount) on top of and kind of parallel to the original, naturally-aspirated power curve. Theory: Now, if you are patient, you can put a large enough turbo on it that by the time it spools up, it will be up near redline, so a rising boost curve like a centrifugal supercharger will result, with easier exhaust flow and less backpressure. The beauty of the centrifugal compressor is that it has so many options surrounding it.
Going from the metric 2 3/4 pipe even on a factory y pipe to 3" after kills bottom end on the 4.8 or 5.3 . 2 1/2" pipes kill power everywhere . Do almost anything you want intake side the ls likes it . The exhaust side is SENSITIVE to changes on a truck !!!
Awesome Content and Information Brother, 👍 So what are your thoughts on BTR Norris Cam on a "Torquer" 416 Stroker (N Aspirated) swap into Heavy 5400 lb Lifted 96 Toyota Land Cruiser "Triple Locked ? Thoughts
Truck norris cam is just a 112-114 torque cam with high lift on 107 Lobe Center. This will have more overlap and lope than usual cams with 112+ lobe centers like Crane cams in 1980's had 112 lobes with low compression ratios of that time Competition Cams Created the High Energy Cams with non symetrical Fast open slow close hydraulic ramps and 110 lobe centers. This added more effective duration and overlap boosting power at the top the tight lobe center makes strong mid range and more cranking dynamic compression while having lower torque cam duration specs its a torque cam on tight lobe centers high lift for more dwell time beyond peak flow or stall in stock cylinder heads. Should make a nice street cam w/o loss of vacume lopey idle strong bottom and mid with good top end.
Please run the set up you did with all the cams a month or so ago to get a good apples to apples comparison. The LY6, long tube, Holley management, truck manifold, etc.
@@richardholdener1727 why wouldn’t you want to test it with the same variables you did as all of the others? Do you not want a constant? That’s a pretty run of the mill truck set up for the truck cams.
Richard, that Truck Norris cam is absolutely incredible! What an improvement from 2500-2800 and up. Way to go BTR, really impressive. It's a bit of a PITA but great data and super useful with different displacements. Maybe you could run an adjustable timing gear and make plus and minus 3 degree runs. Like retarding the cam to lower dynamic and run out more on the top end or advance it for higher dynamic and make power earlier. I've seen a 20psi drop in cranking compression test simply by retarding the cam timing. The Truck Norris cam might be able to get the low end torque back with gen 4 VVT.
For all the truck guys that want a cam and chop but don't want to do a converter, here's a tip, get more gear. Minimum 4.10 to 4.88 depending on tire size.
Definitely agree here, 5.3 with stage 2 high lift, 4l60e and stock converter, 4.10 gears and 35” bfg’s. My rule of thumb after doing the swap is with a 4l60e: stock tires= 3.73-4.10 33”=4.10 35”= 4.10- 4.56. Definitely wish I’d have done the 4.56.
Richard rules! Hey man I love your Honda content too and I was curious if you had any stuff you could share with us about h22, h23, and f20b engines as they are wildly popular swaps where the b series have gotten to expensive. Also, any Honda J series plans for the other guys series? Love the content man. Thanks for helping me understand engines better!
I've bought the Truck Norris cam along with BTR valve spring upgrade && lifters ..... I'm wanting now to upgrade my cylinder heads ... any suggestions on a good cylinder head .? I'm thinking Trick Flow or AFR but idkk ... my engine is a 2009 5.3 in a Avalanche 6L80 Trans && running a stock converter ... && as always Thanks for your time Richard YOU DA MAN .!!
I went from 1"3/4 to 2" pipes on my old shovel head, i don't have a Dyno but I didn't have to White Knuckle and clinch to hang on to the old girl like before, so went back to 1 3/4 but 2 into 1 seems to work the best on Dyno, I wonder if that's a residence thing?
I was hoping to see u do testing on this camshaft w a more stock 5.3 so the mass of ppl could see the power gains from a 5.3 application that is more typical of a daily driver 99+ sierra / silverado. Truck I was dying to see Richard do testing w this cam but it's a 5.7 w modified heads was curious of hp / torque #s from a stock 5.3 w hwaders
Its nearly impossible to gain anything noticeable under 2500 over a stock truck cam. Car cam yes, truck, no. I don't drive around flooring it everywhere.
Such great information! Thank you! Have you run the Truck Norris Cam with VVT? I’m curious to see if you are able to play with the torque and max hp with VVT?
@@adrianlaverick8040 I spoke with one of the Tech’s at BTR about 8 months ago, and he said they have not made a VVT Truck Norris Cam for the older trucks. If my memory serves me right, from that conversation, they have been working on one for the newest Silverado motors, but I believe 2018 and older require a VVT delete if you choose to go with the Truck Norris Cam.
@@TheLmusgrave that's sort of that I thought, my 03 doesn't have VVT, so I am not really worried about it. But I had thought about getting an 07-10 which would be vvt
@@richardholdener1727 I should have specified also, Im looking to build an LM7 with flat tops. stock heads, truck intake, holley manifolds and was wondering what a truck norris cam would make.
On a NA 416 Lightweight Forged Stroked 6.2 with a BTR Norris cam for a Low End Torque Swap into 4WD, would 1" 3/4 Triflow Header help scavange, Which Cyclinders should be match on LS (1&5, 3&7 ect May be Limited on Headed "Fit" due to front axle & Transfer Case
Do you think a 6.0 with flat tops, 706 heads and a TBSS intake would optimize the TN cam? By optimize I mean match the rest of the components to the operating range of the cam?
I'm curious to see what mine will make next week after a tune on a chassis dyno. Truck norris cam, 6.0 @ 10.5:1, cnc 317 heads, ported tbss intake, longtubes, 6L80E
Setting up daily driver boat towing vehicle... rarely seeing over 4k rpm. Picked up an 08 toss intake, will be getting a truck Norris cam kit and probably roller rockers. Stepping up coils and probably a box just fora clean burn. Plan on the ebay $2300 twin turbo setup.reviews look like it's about as complete as they come. Current engine has 706 heads and plan to find a junk engine to rebuild with the same. Plan on .060 over piston with longer rods and balanced and blueprinted.It is an 06 flex fuel. Build is strictly about pulling power and very rarely stop light fun. I'll be happy with gas mileage that doesn't drop much or stays the same, and pulls the boat better. I need to figure out fuel system.advise on injectors, pump, upgraded waste gates, heads if you think I'm better off getting something other than my current 706. Bottom line is bullet proof bottom end that goes for forever with more low end pulling power.being in Florida I'm to far away to come let you help build and tune it but I'd love to have your input and make sure I accomplish my goals.
If you'd prefer to email and keep this off the record my email is alcaddymech79@gmail.com if that let's you give advise without looking bad when the build doesn't go according to plan.
Does an x pipe change anything? Does an x pipe on a modified LS make a different power curve than a stock LS? I was curious how that longer tube plus muffler made a dip, if an x pipe or h pipe would increase the loss, or make a gain?
@Richardholdener I'm doing and iron block ls1 with a btr truck norris cam, ls1 flat top pistons no valve relief, and 243/799 heads. Static compression is going to be in between 10.5:1 - 11:1. With this cam and compression and in your opinion do you think I'll be ok on 93 pump gas?
So when I did the cam swap no issues with the motor but I used LS7 lifters first and I used new trunion upgrade from Michigan Motorsports. I found 2 collapsed lifters so I too all the LS7 lifters out and went to stock Melling lifters but ever since the cam I get weird tick but it’s all the rocker arms. Does anyone else have this issue? 6.0 LQ4 , Truck Norris Cam, Stock pushrods, trunion upgrade stock lifters.
What are the specs on the Truck Norris cam? Heard so much about it, and the power curve is awesome in how it just hangs close to peak power for 1000 rpm. Hard to miss gearing with an engine like that. But that engine should be awesome with Mast heads and 2.08 intake valves. That's about maxed out for a 99mm bore.
Hello Richard. Great Videos. Trying to install the Truck Norris NSR Cam. On my 5.3 LS Engine, I have started pulling apart my front end and tried to slide in my dowels into the oil ducts, on the drivers side I was able to slide dowel all of the in but on the left passenger side, i wasn't able to slide in the dowel all of the way because it stops half way. I have turned my cam shaft several times but it seems my lifters are preventing my dowel from going in. How do I correct this? OBTW, I am here in Elk Grove
I suspect I will need to pull the heads, remove the lifters and the lifter trays, pick up the lifters back into the tray, install the cam, then insert the tray with the lifters then reinstall the heads. How does this sound?
Hey Richard , I have a 2002 5.3 and I’m interested in getting the truck Norris cam, I just want to know if weather I will have to do valve springs , and also will my stock push rods work with a truck Norris cam?
@@richardholdener1727 thank you for the reply Richard! Also one more question, will the stock push rods work or will I have to get the ones they offer in the BRT website with the cam kit , it’s the 7.400”push rods, they offer it in the kit or none , I just want to know weather my stock ones will work with the truck Norris cam
What do you think about E 85 for my stock LQ4 I’m in SLC is it a hassle to buy to run in my car. I’m doing a ground up build and I have the bigger fuel pump with-8 PTFE fuel lines
Alright Richard. You might not be able to answer my question. But what would be the best camshaft to get for a 2,500 pound car with a 2002 6.0L SUV engine in it.
I have a 07 5.3, i considered this set up...but Im concerned about having to do the cyl cancellation along with this cam pkg I would like a lil more towing zip but Im afraid of sacrificing fuel mileage. the truck already is sorta a pig on fuel now in stock form Anyone have real world experience with this set up as far as that? I also wonder if it would pay a guy to just put a junkyard 2014 and up stock motor in his truck as they are rated I believe at 360 365 hp stock. Richards combo here made 400 hp but its modified and bored bigger.
I ran a (216/220 .600 110) and a (228/232 .600 108) on a 07 Silverado nnbs no matter what the gas milage was trash, i boosted it 700-800hp and my gas milage was way better. When i have a chance ill try to get a mpg.

Hey Richard, I have a 454 30 over with a small dome piston and a comp cam 574 inch lift. Is AFR 320cc aluminum head a good fit? Or what would you recommend?
I bought .660 dual valve springs for a bigger cam. I have since decided to get the truck norris cam. Is it possible to run too strong of a spring for a smaller camshaft like the truck norris? Most people are suggesting bee hive springs but I already have these .660 springs.
I'm thinking about putting the truck norris nsr cam in my 05 silverado 5.3l but I have 162,000 miles wonding if that's to many miles on factory springs

@@charlesbeard8823 you would have loved the 4.56s
Richard rules! Hey man I love your Honda content too and I was curious if you had any stuff you could share with us about h22, h23, and f20b engines as they are wildly popular swaps where the b series have gotten to expensive. Also, any Honda J series plans for the other guys series? Love the content man. Thanks for helping me understand engines better!
NOT MUCH H SERIES TESTING
Can you test this cam with a y pipe and single muffler? I’m curious if it would change that low end torque
I've bought the Truck Norris cam along with BTR valve spring upgrade && lifters ..... I'm wanting now to upgrade my cylinder heads ... any suggestions on a good cylinder head .? I'm thinking Trick Flow or AFR but idkk ... my engine is a 2009 5.3 in a Avalanche 6L80 Trans && running a stock converter ... && as always Thanks for your time Richard YOU DA MAN .!!
you don't really need better heads-but the tfs 205 heads work well or ported stock 706/862
Thanks Buddy
I went from 1"3/4 to 2" pipes on my old shovel head, i don't have a Dyno but I didn't have to White Knuckle and clinch to hang on to the old girl like before, so went back to 1 3/4 but 2 into 1 seems to work the best on Dyno, I wonder if that's a residence thing?
Truck Norris vs TSP Chopacabra vs TSP MADD MAXX.. let’s get it done Rich!!!
Could you start the run at say 5k and drag the engine backwards to 1000rpm to show what might be going on down there.?
I was hoping to see u do testing on this camshaft w a more stock 5.3 so the mass of ppl could see the power gains from a 5.3 application that is more typical of a daily driver 99+ sierra / silverado. Truck I was dying to see Richard do testing w this cam but it's a 5.7 w modified heads was curious of hp / torque #s from a stock 5.3 w hwaders
WITH A STOCK 5.3L MOTOR IT STARTED OUT WITH LESS AND ENDED WITH LESS
@@richardholdener1727 would that dip at the beginning be worse with smaller displacement? Seems like a big stall is needed .to much overlap maybe
@@richardholdener1727 does that mean I will get negative result if I put a truck Norris cam in my stock 5.3 with headers?
@@jayswisher575. You would have more power everywhere. Stock LS heads all have good head flow and love bigger cams. Buy it and send it!
Looks like the factory cam in my 04 2500HD is the right cam for me, probably 98% of my driving is sub 3000 RPM.
Its nearly impossible to gain anything noticeable under 2500 over a stock truck cam. Car cam yes, truck, no. I don't drive around flooring it everywhere.
That's why supercharging is awesome. Just gets you more everywhere.
How good does this camshaft tow? I would think it would do better with the added torque. I sometimes pull my 2wd 87c10 with my 05 5.3 Silverado
Have you done this with turbos? Does it matter how long the exhaust is after the turbo? With mufflers?
Such great information! Thank you! Have you run the Truck Norris Cam with VVT? I’m curious to see if you are able to play with the torque and max hp with VVT?
Can you run the cam with VVT?? Doesn't it have to be a vvt cam? Or am I mistaken?
@@adrianlaverick8040 I spoke with one of the Tech’s at BTR about 8 months ago, and he said they have not made a VVT Truck Norris Cam for the older trucks. If my memory serves me right, from that conversation, they have been working on one for the newest Silverado motors, but I believe 2018 and older require a VVT delete if you choose to go with the Truck Norris Cam.
@@TheLmusgrave that's sort of that I thought, my 03 doesn't have VVT, so I am not really worried about it. But I had thought about getting an 07-10 which would be vvt

What’s your thoughts on the 6.2 L9h vvt motor with stock 821 heads with chuck norris cam?
I would like to see a comparison of a stage 2 vvt cam vs Truck Norris. Do you ditch the vvt? Or keep it..
I would like to see a vid of a 5.3, flat tops, stock everything else and a truck norris cam

Sloppy stage 2 vs truck Norris please .I'm undecided on a 2008 Silverado2500 hd
On a NA 416 Lightweight Forged Stroked 6.2 with a BTR Norris cam for a Low End Torque Swap into 4WD, would 1" 3/4 Triflow Header help scavange, Which Cyclinders should be match on LS (1&5, 3&7 ect
May be Limited on Headed "Fit" due to front axle & Transfer Case
CHECK FIT
Do you think a 6.0 with flat tops, 706 heads and a TBSS intake would optimize the TN cam? By optimize I mean match the rest of the components to the operating range of the cam?
that combo would do the same thing with other cams too
I had that setup and it was gobs of tq even on a btr stage 4 truck cam I had thin cosmetic gaskets too it was quite a peppy setup low and mid range
I'm curious to see what mine will make next week after a tune on a chassis dyno. Truck norris cam, 6.0 @ 10.5:1, cnc 317 heads, ported tbss intake, longtubes, 6L80E
Find a way to add compression or those heads will disappoint
How is it 10.5:1 with those heads? Did you get them milled?
@@EXTRA---LARGE---FARVA likely a made up number. Unless there are domed pistons in it it’s gonna be more like 9.5:1.
I be would say around 320hp at the wheels
Are you willing to talk with someone about a bench build? What I want vs what's out there are 2 completely different things. I view you as the guru.
ask way-there is a lot out there that works very well
Setting up daily driver boat towing vehicle... rarely seeing over 4k rpm. Picked up an 08 toss intake, will be getting a truck Norris cam kit and probably roller rockers. Stepping up coils and probably a box just fora clean burn. Plan on the ebay $2300 twin turbo setup.reviews look like it's about as complete as they come. Current engine has 706 heads and plan to find a junk engine to rebuild with the same. Plan on .060 over piston with longer rods and balanced and blueprinted.It is an 06 flex fuel. Build is strictly about pulling power and very rarely stop light fun. I'll be happy with gas mileage that doesn't drop much or stays the same, and pulls the boat better. I need to figure out fuel system.advise on injectors, pump, upgraded waste gates, heads if you think I'm better off getting something other than my current 706. Bottom line is bullet proof bottom end that goes for forever with more low end pulling power.being in Florida I'm to far away to come let you help build and tune it but I'd love to have your input and make sure I accomplish my goals.
If you'd prefer to email and keep this off the record my email is alcaddymech79@gmail.com if that let's you give advise without looking bad when the build doesn't go according to plan.
Does an x pipe change anything? Does an x pipe on a modified LS make a different power curve than a stock LS? I was curious how that longer tube plus muffler made a dip, if an x pipe or h pipe would increase the loss, or make a gain?
it might
How would this cam perform in a 1972 k5 Blazer, 5.3 with turbo 350 with 2300m stall, 3.73 gears on 35" tires. Thank you Vince
very well
Did u mention the norris cam has more power / torque gains than the stage 3 btr truck cam?
They do not under stand , you need more torque at a cruise . And you do not need to spin past 5500 .
I wanna see... ls3 bottom end + 706 heads + cathedral fast 102 intake + truck norris + turbo on e85 = pull your house down torque
I'm thinking of the exact combo with my 6.0 bottom end
Have a hard time deciding on norris, sloppy, or the weekend warrior cam. Going into my weekend Driver. Need help. On 5.3. , 4l60e. .
I’m in the same boat let me know how it goes
How does buy any camshafts from you? My lq4 needs a bumpstick
@Richardholdener I'm doing and iron block ls1 with a btr truck norris cam, ls1 flat top pistons no valve relief, and 243/799 heads. Static compression is going to be in between 10.5:1 - 11:1. With this cam and compression and in your opinion do you think I'll be ok on 93 pump gas?
yes
Quote of the day... "yoga pants show all the data" - Tyler Mcintyre
@RichardHoldener have you tested a stock crank, stroke but overbore 4.8l?
I RAN A 4.8 CRANK IN AN LS3 BLOCK-SO YES
So when I did the cam swap no issues with the motor but I used LS7 lifters first and I used new trunion upgrade from Michigan Motorsports. I found 2 collapsed lifters so I too all the LS7 lifters out and went to stock Melling lifters but ever since the cam I get weird tick but it’s all the rocker arms. Does anyone else have this issue? 6.0 LQ4 , Truck Norris Cam, Stock pushrods, trunion upgrade stock lifters.
I wonder how a x pype would effect it
What are the specs on the Truck Norris cam? Heard so much about it, and the power curve is awesome in how it just hangs close to peak power for 1000 rpm. Hard to miss gearing with an engine like that. But that engine should be awesome with Mast heads and 2.08 intake valves. That's about maxed out for a 99mm bore.
Hello Richard. Great Videos. Trying to install the Truck Norris NSR Cam. On my 5.3 LS Engine, I have started pulling apart my front end and tried to slide in my dowels into the oil ducts, on the drivers side I was able to slide dowel all of the in but on the left passenger side, i wasn't able to slide in the dowel all of the way because it stops half way. I have turned my cam shaft several times but it seems my lifters are preventing my dowel from going in. How do I correct this? OBTW, I am here in Elk Grove
what dowels
@@richardholdener1727 5/16 Wood Dowels to prevent the lifters from falling.
I suspect I will need to pull the heads, remove the lifters and the lifter trays, pick up the lifters back into the tray, install the cam, then insert the tray with the lifters then reinstall the heads. How does this sound?
This video of yours is super helpful. ruclips.net/video/cIq2xxu79NA/видео.html
head removal is not required for a cam swap
Please test a comp xer 224/230 581/588 114lsa in a stock LM7
Hey Richard , I have a 2002 5.3 and I’m interested in getting the truck Norris cam, I just want to know if weather I will have to do valve springs , and also will my stock push rods work with a truck Norris cam?
Yes it will need springs-though they also offer a nsr version
@@richardholdener1727 thank you for the reply Richard! Also one more question, will the stock push rods work or will I have to get the ones they offer in the BRT website with the cam kit , it’s the 7.400”push rods, they offer it in the kit or none , I just want to know weather my stock ones will work with the truck Norris cam
@@richardholdener1727 also I have stock valve train , pretty much stock everything other than some long tubes on the 5.3
What do you think about E 85 for my stock LQ4 I’m in SLC is it a hassle to buy to run in my car. I’m doing a ground up build and I have the bigger fuel pump with-8 PTFE fuel lines
NO NEED FOR E85 IN A STOCK LQ4

would this cam be efficient to run with twin turbos on a 6.0? is the cam lobed for boost?

Would an x pipe help with those frequency issues ? 🤔
MIGHT CHANGE THINGS
Alright Richard.
You might not be able to answer my question.
But what would be the best camshaft to get for a 2,500 pound car with a 2002 6.0L SUV engine in it.
what do you plan to do with it?
@@richardholdener1727 I want to drive it on the street. And maybe also put a turbo on it later.
Would the truck Norris can do well in a a6 c6 corvette with the ls2
I have a 07 5.3, i considered this set up...but Im concerned about having to do the cyl cancellation along with this cam pkg I would like a lil more towing zip but Im afraid of sacrificing fuel mileage. the truck already is sorta a pig on fuel now in stock form Anyone have real world experience with this set up as far as that?
I also wonder if it would pay a guy to just put a junkyard 2014 and up stock motor in his truck as they are rated I believe at 360 365 hp stock. Richards combo here made 400 hp but its modified and bored bigger.
I have 2007 5.3 silverado with the btr stage 2 cam check out some of my videos
I ran a (216/220 .600 110) and a (228/232 .600 108) on a 07 Silverado nnbs no matter what the gas milage was trash, i boosted it 700-800hp and my gas milage was way better. When i have a chance ill try to get a mpg.
Hi have seen many of your videos and I have a question I have a 13 suburban ltz 5.3 4x4 doing a dod and vvt delete was wondering would a truck Norris cam be a good choice with stock trans and converter only mods done are cai and catback

@@richardholdener1727 what heads would you Recommend to install for max power ?
Does adding an xpipe or h pipe change the low end tq?

So what’s better for drivablity and low speed torque? With stock stall converter? The BTR “torque cam” or the “Truck Norris” ?
have not driven them both
@@richardholdener1727 well WTH instalL them in your red silverado and give the people what they want.

Hey Richard, I have a 454 30 over with a small dome piston and a comp cam 574 inch lift. Is AFR 320cc aluminum head a good fit? Or what would you recommend?
That afr head is a little large for that 454 a 290 is perfect
How much more fuel would it use ?
What size injectors did you run with the test?
60s
I bought .660 dual valve springs for a bigger cam.
I have since decided to get the truck norris cam.
Is it possible to run too strong of a spring for a smaller camshaft like the truck norris?
Most people are suggesting bee hive springs but I already have these .660 springs.
The 660 springs have more seat and open pressure than you need and more coil-bind clearance than optimum (but you can run them)
@@richardholdener1727 Ok thank you. Is having more coil bind clearance something to worry about?
Will this work with a 2300 stall converter
The truck intake has a small opening at the throttle body junction. Could that hurt power up top?
its the runner length
Could you expect good gains with the truck norris cam swap only, nothing else?
you need a tune as well
all I want to know if a 6.0 chevy 19370163 with a truck norris and lsa super charger will pick up lower end torque
COMPARED TO WHAT?
Hello Rich you think the Norris cam will be good for my 5.3 swap in my Iroc ?
yes
@@richardholdener1727 Great ! Thanks for getting back to me

Only make one change at a time. Geee
How would the truck Norris cam be on a LQ4 with 243’s and long tube headers with a 2400-2800 stall?

Would you say there is a better cam for this same setup with running a 3000 stall or higher? Running a 4l80e.
