4.8L LS VS TRUCK NORRIS NSR-CAN YOU ADD 50 HP WITH A JUNKYARD LS CAM SWAP WITHOUT CHANGING SPRINGS? 

Would it be good for a daily driver as well?

@@Valdemar-Perez-III my cars not a daily but I wouldn't hate it if it was. Cruises nice on the highway and around town it's not so aggressive it's un drivable. (plus it it has a great idle lope)

already did that-video soon

@@richardholdener1727 Thank you!

ss2 requires springs and is a lot bigger than the tn

Ok understand.. what about the others cuz fairly close.. TSP and the BTR is nearly identical, but I’d like to see those compared to the summit “drop in”.. Apparently a lot of truck guys like that one cuz it claims “no tune needed”

@@richardholdener1727 I’ll even buy the 8712, drop ship it to you, run it, get numbers and ship it back to me 😊

Good luck!

Take more than that off the heads... 😁

I went a little bigger with a sloppy stage 1 by elgin and my twin brother is using the truck norris on his 4.8 build so we can compare. We used identical springs and brass trunion upgrade though

Should be a factory cam

Who will build the transaxale to take the torque. I think the factory detuned the 5.3 just to keep things in one piece. Otherwise I like this idea.

@Dr. Reason I have a "Built" replacement transmission for now from Triple Edge Performance. When is fails im going to a 4T80. I wish the six speed could be swapped in.

THERE ARE PLENTY OF VIDS WITH ENGINE NOISE

WE USE THE STOCK RINGS-JUST ADD GAP

Nah, he uses his hands to steer and shift.. He actuates the valves with his tongue..

And if he has nitrous, he hits the button with his.... Well, never mind. 😳

@@davelowets i know he pees NOS 🤣

then you should be happy with your choice

@@richardholdener1727 I am. But would be willing to lend it for "science "

balancer fingers are not very strong

The real tool can be had on amazon for 35 dollars

Or just get yourself a Harbor Freight Ultra-Torque Hercules 1/2" Impact for $179. It'll rip it right out with no issues.

@@UserUser-ku6gm To remove the bolt?

Richard has already done this with the normal Truck Norris cam, but I think it was on a 5.3 with springs. It will make another 10ish HP is all so for most guys on a tight budget this is an awesome option!

springs won't change anything-except possibly lose a touch of power

@@richardholdener1727 people must think they hold in more cylinder pressure with stiffer springs.

@@thedude7726 If the engine was gonna be boosted then yes..

My understanding is that the spring help control the higher lift. If not you would float a valve.

I googled it myself because I didn’t catch the specs either... Specs: 212/22X .498"/.498" 107 LSA

The nsr cam will make slightly LESS power compared to the normal truck norris cam due to the lower lift duration. .498 on the nsr version vs I believe .560 on the normal version.

Good question! I forgot to include specs

In a 5.3 the NSR makes 3 less hp (the dynos for both are on BTR's website)

@@rehn1kri Revallier ?

Stock Bee-hive springs, fairly low lift, small valves, not an issue.

@@davelowets stock cams with stock valve springs even have issues if they aren’t LS6 springs

@@ZONES89RS Did you watch the video? 200,000 mile springs, and the motor ran right to the end of it's power band, WITH the larger cam, WITHOUT any issues. I'd say they're fine.. 🤷🏻 Edit: "NSR" on the cam means, "No springs required". A reputable company wouldn't advertise that if it was going to cause all kinds of issues.

@@davelowets it’s probably the LS6 style newer springs. I’ve spun those to 7200+ myself. The older springs were just trash and didn’t like 6000

@@davelowets yea, that’s weird and confusing because if that’s gen 3 springs it doesn’t make sense. Seen it time and time again calve float with stock springs and cam and even with Richard

2800

ask btr for a Truck Norris-very easy

yes it should have oil pressure when cranking-when new-it might take a few ticks-that's why we pressurize the crankcase prior to spinning it over on a new motor

WHAT USUALLY HAPPENS IS NA GAINS WOULD BE MULTIPLED BY PRESSURE RATION (THE GAINS OFFERED NA OFTEN INCREASE WITH BOOST)-BUT NOT BECAUSE BOOST LIKES THE HIGH-LIFT CAM BETER-BOOST DOES THIS WITH ANY TYPE OF NA POWER GAIN

THERE WAS NO HIGH LIFT CAM RUN ON THIS TEST

Roller rockers on a small cam won't do much at all.

On top of the two TN cams, would you be able to run the 1.82 roller rockers on the nsr cam on the stock 4.8 and have it nearly equal the og TN?

IT ALREADY (NEARLY) MATCHES THE HIGH-LIFT TN CAM-ROCKERS REQUIRE SPRINGS.

@@richardholdener1727 I knew it would require springs. Just didn't know if there would be enough clearance for the combination and how that would compare with the OG TN.

panicked reactions?

Panic?

Panic at the disco?

I ran stock lifters-the one replacement was another stock, used lifter

2800 LIKELY-CHECK WITH BTR

There are plenty of LS1/LS6 cams out there that have great driveability and make more power being no intended for a heavy truck. Hell, the LSA you want for a car cam, rule of thumb.. Auto trans, about 114 LSA. Manual trans, 112 LSA. If ita a 97 LS1, find some cheap 799 heads, LS6 or LS2 intake and get a btr stage 1 LS1 cam. Or the SDPC (Scoggin Dickey) LS6 Power Max or LS6 Power Max Plus camshaft. I'm running the Max Plus in my 98 WS6 t56. After over a decade and 85k+ miles.. I ditched the LS6 cam. Powerband went from starting at above 4k rpm's with the factory LS6 cam, down to about 2500 rpms. But I also have 4.10s to be able to quickly get into the power-band. But point blank.. Find an actual aftermarket cam for LS1. Besides being more cubes, also lil more compression.

LT Tolman is running a turbo 8.1 and cataloged the build on RU-vid.

@@rcairforceone I am wanting to see what some of the upgrades produce on the dyno. LT did a good job but I am not sure I want to go the turbo route yet due to funding. I am putting one into a 79 trans am and have done the raylar BP203 cam and roller rocker so far.

yes

SWEEEEET!!

I'm honestly surprised he didn't add that in this video

yes it works in the 5.3l

we reuse

It's cheap enough to replace, for extra insurance. I usually replace them, but that's just me.

same

not on the nsr version

Probably 20hp

​@@sstevocamaro I don't even think it's that much

It varies based on the cam (the bigger you go the bigger the difference) but it's generally 10-20 hp. The standard Truck Norris cam only makes about 3 hp more than the NSR version though (but that's ~.550 vs ~.500).

higher cylinder pressure (nitrous or boost) requires smaller gap for voltage to jump or you get misfires

the second one

it needs to be tuned

I have-the TN is better

we did not rev the motor to valve float

@@richardholdener1727 thanks, yes I was sure you would have commented if that happened however just curious what rpm you hit during the test, graph appears maybe 63-6400ish?

WHEN YOU SPIN THE CAM-IT PUSHES THE LIFTERS INTO THE PLASTIC LIFTER TRAYS-THEY HOLD UP THE LIFTERS.

the cam is not smog legal that I am aware

TUNE REQUIRED WITH CAM SWAP

there won't be

What about with the non NSR cam with good springs?

@@billybadass411thefirst9 It'll make 3 hp more on a 5.3 (the dynos for both are on BTR's website)

Question guys. Stock lq4 862 heads Holley Sniper Efi msd LS series. Would there be a change in performance with springs and hollow valves with no stock cam? Thinking about a TN cam later. A

@@billybadass411thefirst9 bind is the concern and float at 5 k and up rpm

no stage-just truck norris nsr

yes

torque converter for aur transmission, we use stock or the german chains

Is there a certain type of converter the stock one to buy?

converter stall speed is also based on power output

@richardholdener1727 gotcha. I have a 4.8 that I put in a g body. I have both the tmbx and the tlbx converters laying around. Just trying to figure which one to throw in with this cam is all.

I would pick the higher stall speed

@richardholdener1727 ok thanks for confirming Richard!

​@@richardholdener1727Will you test the Madd Maxx camshaft?

it will work with the right tune

Interesting concept for a decent cam for my afm deleted 5.3 in my avalanche

cam requires a tune

I wouldn't drive it without a tune..

243 is good

cam works with any heads

MIGHT BE OKAY...ISH!

🎲 🎲

Is this a troll?!? Lol. He runs that cam in everything! Although I can't say for positive that I've seen him run it in a 4.8, so maybe that's why you're asking...?

THAT IS WAY PAST THE POWER PEAK-NO REASON TO RUN IT THERE-BUT IT WILL ALREADY RUN TO 7000 WITH STOCK SPRINGS.

@@richardholdener1727 I run them there all the time. Have to extend the shift to keep it away from peak torque to keep the SBE alive with big boost. Routinely run 7500+ on mine. Just curious if the tight LSA cam will continue to pull on a 4.8 w decent springs. Summit "Stg2" pulls steady to 7300ish before it drops off and has been my "go to" budget turbo cam. I shift it at 7500 and have been knocking out 5.50's. Curious if the smaller cam with tighter LSA would give me more midrange and quicker "spool" vs the summit stg2 without falling off up top.

@@AdamOpheim Shift it earlier, and see what (if any) difference is to your E.T.'s..

ls doesn't require intake removal-and the lifters are retained by the lifter trays

@@richardholdener1727 well that's too cool.

On the gen 4 motors, there are little holes in the front of the block, under the cam plate, that runs under the lifters when they are in the up position in the tray. I shove wooden dowels in these holes, and the dowel will hold the lifters up and guarantees that they can't fall down into the block. I've never had it happen, and I don't know if it COULD be an issue, but I just don't trust that a high mileage tray couldn't be worn out to the point that it could possibly let a lifter slip out when the cam is out, and end up with a lifter in the oil pan.

are you asking if it makes more power with shorty headers or will the gains be less with shorty headers?

@@richardholdener1727 I’m asking if the power gains would be less

2800

Just replace the dod lifters leave the rest

replace them

Just imagine your DoD lifters as little grenades waiting to go off in your engine. Replace them.

@@ChurchAutoTest 😆 Exactly... 🍻
