    After seeing what one of these Truck Norris cams actually does in the wild. Where the engine had stock OEM flat top pistons with a TBSS intake and a set of out of the box Summit headers with a full exhaust to the back of the car (1980 Monte Carlo) running a 4l60E trans. I was very happy with the performance and even the fuel mileage that this performance cam provided. And is why we went with the same cam and flattop OEM pistons and 862 heads for our 5.3 LM7 build thats going in our 86 Camaro in the spring. If it makes anywhere near the 400 hp (NA) we will be very happy with what we have. Having a nice street car (with AC) With 400 hp on pump gas thats getting 20 plus MPG is about all you can ask for these days.

    I put a 6.0 in a ‘05 Suburban with the BTR Stage1 Truck cam, it can idle and pass CA emissions on the factory 5.3 tune. I just found an idle clip of “Truck Norris”, IMO that would be miserable with the stock tight converter these trucks came with and I don’t think it’s going to be happy at a factory 550rpm idle. In short, drivability of the Stg1 probably better and you can sneak it past the Gestapo every two years. Thanks for another great vid Richard!

    • @natricjol
      @natricjol 2 года назад +2

      Part of the TN is it works great with stock converter. It's made to have a rowdy idle while actually being smooth with the stock converter. Lots of tuning time (correct ve table then adjust maf and timing over and over) gave choppy but emissions worthy idle with good driveability. Tows better than stock too.

    I agree with you that if you have already done a cam swap that it's probably not enough difference to make a difference between the cams to justify the cost and effort to change it. But if you have a stock cam and want to get the best upgrade cam I think the the truck Norris cam is definitely the one to get. Thank you great video. Just to let you know. Your videos are awesome I have learned a lot and there's things I was thinking about that were wrong and others I had a pretty good understanding of and your videos have shown me with dyno data where I was right and wrong and why.

    Really wish people would stop thinking the TN cam outperforms ANY stock cam for towing (1500-2500rpm). Unless you test the rpm curve from idle, everyone and their mommas knows larger duration, more lift and a tighter valve sequence makes more power at 6500rpm. I would take a stock 5.3 VVT cam over ANY aftermarket cam for towing or low rpm torque, that’s a fact.

    Was going to order a BTR stage 3 or 4 cam, but I think now I'll get the Truck Norris. I have a 5.3L LM7 in my Z71 with Speed Engineering 1 3/4" long tubes and off-road y-pipe, speed engineering air intake with heat shield, 4.10 gears, Yank 3000 stall, and tuned with HP Tuners. Since I don't currently have an upgraded camshaft, I think Rich is correct that the Truck Norris cam would be my best choice and then I can work on optimizing my tune for 91 octane premium fuel that we have out here (these fuel prices are horrendous). I like that it makes more torque than all the other cams and in a heavy truck that I tow with I need all the torque I can get. I could care less about a few less peak HP up top since I don't stay at high RPM. I am going to raise my shift points to around 6500 RPM.

      All of the cams would perform the same in comparison to each other. Add x amount of power to each

    • @jacobvanhalteren7452
      @jacobvanhalteren7452 2 года назад

      add 11% more power for sure.

    • @azreeal1
      @azreeal1 2 года назад

      They won't make 11 percent more power just because of the displacement. The 5.3 will peak at a higher rpm because the airflow requirements are relatively less than the 6.0

    Personal Observations Made Comparing The Truck Norris To The Stage 1-4:
    TN Had The Tightest LSA Of 107. It Also Has The second Highest Amount Of Overlap (when guessing Exhasut duration is 222)
    STG1 Had The Least Amount Of Overlap And Widest LSA 112. It's "RPM HP Hump" Was The Earliest. It Made Less Overall HP And Torque Because LSA Was Was Furthest From Optimal For Engine.
    STG 2 Had The Next Shortest Amount Of Overlap And A Slightly Tighter 111 LSA. This Cam Didn't Really Shift The HP Hump From The Stage 1 Further Up In RPM But Rather Widened The Hump. Power Did Increase From STG1 Suspected By The Slight Lift Increase And Tighter LSA Approaching Optimal.
    STG 3 Had 3rd Shorted Amount Of Overlap And Again A Slightly Tighter 110 LSA. The Change In Overlap From 2-3 Is Increasing However The HP Hump Isn't Really Shifting Higher Up In The RPMs. The Increases Appear To LSA Approaching Optimal As It Gets Tighter.
    STG 4 Had The Most Amount Of Overlap And More Overlap Than The TN Cam. Oddly The LSA Went Up To 111. This Cam didn't Really Shift The Power Much Higher Up The RPM Given More Overlap. It Did However Make More Power Than The TN. The Increased Overlap Seems To Have Traded More Low End To Compensate For Having The LSA Further From Optimal For This Engine Compared To The TN 107LSA. I Think If The STG4 Kept Same Overlap But Ran A 108-9 LSA The Power Gain Would Be More Higher And Less Behind The TN In The Lower RPMs In The Curve.
    I'm Starting To See That Overlap Isn't Trading 3-4RPM Power And Shifting The Peak RPM Power Range As High Up As I Think. It Appears To Be Trading Much Lower RPM Power 1500-3000 RPM And Slightly Shifting The RPM It Peaks At While Raising The Peak.
    The Duration Bias. The TN Appears To Have The Largest Duration Bias With Much More Duration On The Exhaust. This Appears To Flatten/Carry The Peak Power Further Out. From What I've Read Doing This Does Indeed To Show This True. However It Says It Trades Low End When You Bais The Exhaust For More Duration. This Isn't Really Seen With The TN Cam... However It Is Possible Since The LSA Is More Near Optimal That The STG4 Cam It May Not Show The Trade Since The STG Is Loosing Some Of It From LSA Being Further From Optimal.
    These Are Personal Notes.

    This music that you start the videos out with is very annoying and goofy. But I've learned to like it and now every time I hear it that rave beat ---- I know I'm about to get some good dyno information and I immediately watch. :)

  • @hugokatz

    Here's an idea for a test, that most Gen IV folks would want. Test the Truck Norris against VVT performance cams, with the Comp Cams phase limiter. Would a stage 3, with VVT pick up enough torque, that it might have the best of both HP and torque. Could that be better than the Chuck Norris for a heavy truck. Pretty please. Or maybe run the Comp Cams 216/228 114 lsa with VVT, against the Chuck Norris. I would watch that one a dozen times.

    • @richardholdener1727
      @richardholdener1727  Год назад +1

      I can't run VVT cams-phaser limiters would negate the gains offered by vvt

    Stage 2 truck cam and truck norris have similar lift and duration but the lsa is tighter on the TN sounds like Mr Vizard is right

  • @utahcountypicazospage5412
    @utahcountypicazospage5412 2 года назад +1

    So it seems like exhaust controlls how high the cam revs even with low intake duration lsa is also a big factor seems the trade off would be rough idle for not much power .torque yes but hp seems low for how rough the idle quality is

    Hello, I always watch your videos, and I learn a lot from them. I have a stock 5.3 Lm7 engine and 862 heads with a 68 inlet and 90 outlet turbocharger, with a fitech injection system for 750hp with a 102 throttle. My question is what do you recommend for my configuration? , and also if you know the gap between the rings and the pistons, I understand that it is different when it is turbocharged for street use. Thanks for the help.
    What cam do you recommend for my configuration ?
    Thanks

    I commented on 1 of the other cam comparison videos. In short I am building a 408 for a Silverado. In my case the truck Norris is the winner. At the end of vid, you hit on probably the most important topic: the tune. If I don't have access to a tune shop w a dyno, what's the 2nd choice? I live in a small town in Montana and am not aware of any shops out here.

    @matthewwardwell1550 2 года назад +1

    Richard I love your videos but the one thing you don’t talk enough about is with these truck cams you make all the torque and horsepower you want but guys need to know DOES IT NEED A STALL CONVERTER? Guys ask me all the time after watching your videos like the 54-454-11 comp cam GREAT CAM however you have people that may not know as much as say yourself or myself a engine builder and they buy the cam because they seen the 120hp gain but don’t add a stall lol and of course they are unhappy it won’t idle it won’t stop lol please know just helping love your videos bud just maybe make one called do I need a stall or no and maybe list that after say .580 lift or whatever I would run a stall. My favorite in my comp cam Bible is for instance the old flat tappet XE cams right when you get to “that point” comp cams says it’s not necessary to run a stall but ITS HIGHLY RECOMMENDED LOL RIGHT? because the SOB isn’t going to have power breaks at least for 40 percent of that panic stop lol just friendly help brother keep up the great work!!

  • @jacobvanhalteren7452
    @jacobvanhalteren7452 2 года назад +1

    I'm building an 04 Lq4. Hopefully it has all the factory goodies and it'll get the truck Norris cam, Ported Head and intake, and heads decked to bring compression to around 10.3 : 1 if I've got valve piston clearance. probably balance the rotating assembly so I can spin close to 7k assuming I got the stronger rods and pistons

    • @richardholdener1727
      @richardholdener1727  2 года назад +1

      it won't make power up at 7000 rpm with that cam on a 6.0L-but it will rev there

    • @jacobvanhalteren7452
      @jacobvanhalteren7452 2 года назад

      ​@@richardholdener1727 Any suggestions for a cam that would want to be shifted WOT at around 6.5 - 7k that would still make good low-end torque for light towing and street? I'd probably be doing a Holley terminator with a map switch for transmission control for towing to rev higher before shifting. My goal is 400 + torque and HP - Id probably be building custom headers too.
      And I'd probably do a HD converter with 2000 - 2200 Stall

  • @The_Fat_Turtle

I am going cam motion titan 2 ls1 cam for my new build. Want to see how it works out. Going with a 3200 stall as well and a good combination on the motor. Can you test some cam motion stuff soon? They could be considered "the other guys"!

    I have yukon 5.3 v8 2008 with 4L60E transmission, and DOD DELETED and I will add in my yukon:
    1-long tube HEADERS (Speed engineer)
    2-cold air intake(volant)
    3-full system exhaust with Y pipe
    The qustaion Is which cam should I buy to make more hp and tq:
    1-BTR GEN III & IV LS TRUCK NORRIS CAM
    Or
    2-BTR GEN III & IV LS TRUCK NORRIS NSR CAM
    Another qustaion do I have buy valve springs and pushrods?
    Thanks a lot and you are helping the people who want to get more hp and tq in thiers cars.
