- DESTROKED TURBO LS3! IS THE LS9 THE MOST POWERFUL FACTORY LS CAM? HOW MUCH POWER CAN YOU MAKE? DOES THE LS9 CAM WORK WITH A TURBO? DOES THE LS9 CAM WORK WITH A BIGGER BLOWER? HOW MUCH BOOST CAN I RUN WITH AN LS9 CAM? CAN I RUN THE LS9 CAM IN MY NA 5.3L? ALL OF THESE QUESTIONS AND MORE ARE ANSWERED IN THIS VIDEO WHERE I TESTED THE LS89 CAM AND THREE DIFFERENT COMBINATIONS, INCLUDING A WHIPPLE SUPERCHARGED B15 LSX CRATE MOTOR, A NATURALLY ASPIRATED 5.3L (BEST INFO IN THAT ONE) AND A TURBO 340-INCH DESTROKED (4.8L CRANK) LS3.

Don't be scared to run a LS9 cam on a 5.3 . I have a LC9 5.3 with a LS9 cam S475 T4 turbo running 18 lbs of boost on pump 93 and water meth . The truck weighs about 4000lbs and it is a rocketship . Full boost by 3500rpm . The biggest reason I picked the LS9 was I wanted a clean smooth idle at 600rpm , the exhaust smells clean even with no cats and I get decent fuel economy as well. Do I need more low end torque , absolutely not I have a hard time hooking as is with 29 inch Nitto 555r drag radials if anything the cam helps me put the power down . If you daily your project I can't recommend the cam enough and the price point helps as well. Also remember this cam was designed for longevity in mind as well and is easy on the valve train . Is it at all out race cam no! But it works for my intended. purposes.
I always wondered about the guys obsessed with making torque down low. Seems it might be good for an everyday use truck but maybe not for a car that wants to hook up on the rare occasion it may go full throttle.
If it works for you-then it is the right cam
In short: if you want a good balance of torque and hp use the Sloppy Best or Truck Norris cam 👍....comment for the algorithm!
I have the truck norris cam in my na at the moment 5.3 swapped sn95 pretty happy with it definitely drops off hard around 6300 or so but we need the rpm for the 1 to 2 shift and 2 to 3 shift to keep it on its toes curious to see how it acts with my s475 in spring
@@OAndy2222 damn i dont like that lol.. my 4.8 truck was ls6 cam shifting at 6300 and felt okay, i wanted to do same with my 5.3 and now am 100% sure ill go with the btr hot rod cam
@Honda Service Center I think the truck norris is probably the best bang for your buck on your low end torque i mean i definitely wouldn't mind 7k shifts but also didn't want to spend the time pulling heads and fighting with finding quality lifters the small cam should light up the s475 nice and low in the rpm range tho
Hmmm everyone forgot about the 2004 ls6 cam in a na and turbo back in the day people where in the 8 sec quarter mile range with that cam
@@OAndy2222 dont really care for low end, i will have a convertor to help me out, i just want to shift at 63-6400 rpm without falling out of powerband at all
I think its time for the 455 Buick engine again👀💪🏻💪🏾💪🏻💪🏾💪🏻💪🏾
Yes! I miss these short form cuts of your longer videos. Don't get me wrong, the longer ones are wonderful but I often don't have time to sit through the whole things. Keep it up!
I’m going on a binge watching session! I’ve watched a lot of your videos at least once but I’m setting it to auto play and lettin her roll through your channel. Gotta get them views up. Also going to make it a point to comment a little more than necessary too, gotta get that algorithm rolling. Hope you, your lovely wife and the pups have a wonderful night!
You're the best!
@@richardholdener1727 I actually have a friend who works as a “promoter” not usually with TH-cam stuff but he’s a solid business partner. I plan to get him in touch with you if it’s something he’s interested in doing, and if it’s something you’re interested in checking out.
Thank you again Richard, for your knowledge, and your patients, with us newbs....
Richard excellent info as always usual! Keep them coming please! ✌ 🇺🇸
This video raises more questions than it answers. I suppose that's a good thing, because now I need to do research.
Thanks Richard. I just wanted to thank you for your guidance through you videos on what parts to use one my 88' 5.0 engine in my 66' Bronco. It feels like double the power with one unintended consequence, I got a mean axle wrap. I guess a 4 link is next. Thanks again.
Love it! I still refer back to your hot rod article from 2013 comparing OE cams. A used LS2 cam fell into my lap and I think with better springs it will perform well without requiring other changes (LH6 5.3).
Take it from a GTO guy. Get rid of that damn cam. They do weird things to valvetrain harmonics.
LS9 worked well as an SBE turbo street strip cam. Limited power down low where the rods and ringlands fail. Also where tires just spin on the street. Then made lots of steam above 5500. Loose converter, transbrake, and 7500rpm made it a good turbo cam for me. Took my SBE gen3 5.3 to 8.90’s @ 3000lbs and cruised like minivan on the street. Price point is also hard to beat, that wasn’t really discussed. It’s likely the cheapest “OEM quality race” camshaft out there to purchase new.
How much boost? Id assume 25+
@@Airman.. 26lbs.... though it didn't make much more power over 24. Turbo was done. Was the T4 1.10 AR S475.
@@AdamOpheim more boost will overcome cam shortcomings, less boost will be hp output limited by the cam breathability, you need a bigger inducer, with single turbo setup a 74mm inducer is too small, if your build can take more id suggest doubling it or go 88 or 90 pro mod snails
I know this an old video, in my particular case I saw a pleasing increase with switching to an LS9 cam ( manual g8 gxp). Stock was a dynojet it made 381/376 after the LS9 cam I saw 419/402 with a subpar tune. Interestingly enough TQ at 3000 was up 20ft/lbs with LS9 cam, I totally expecting the reverse.
Since then I’ve added LTs, ported TB, catback and lastly Quality tune. It’s been 80k trouble free miles 😊
I would pay good money to see you have a discussion with Pete Harrell about cam selection as part of his tactical interviews. You’ve done the legwork, and he watches his experiments on track. It would be very interesting.
Huge fan been watching you for a while now keep up the great work, also I just realized your on Netflix on “fastest car” S2:E2
YES WITH CHAD
Cool stuff! Just caught you on Pontiac Power Hour!
Thanks for coming
I still remember the article on the 8000 RPM 5.5 LS3 you wrote for Motor Trend. I still want something like that...plus180 degree headers.
Got it thanks
Would be awesome to see some two stroke engines tested maybe a series on the other other guys. One for the shifter kart and motocross guys!
IIRC Richard the LSA test you did fared better for the smaller displacements
we did a 6.0l iron block with ls3 head ls7 cam and got in the 10 in a third gen camaro 9sec with a big shot
I'm running an LS9 cam in an LY5 block 5.3l with stock 9.9:1 compression, TBSS intake, 92mm TB, mostly stock 799 heads with better springs, and shorty headers in a lightweight CJ5. It makes plenty of torque down low for the Jeep, and it really builds as you rev it out as your dyne graph shows. It's also very civil for just driving around town with good vacuum and a reasonable idle.
Similar to the direction of my current build. For the cam, did you have to change timing cover and reluctor to run that cam? I have a lm7 in my truck, but I believe the one I am building is an L59. Also is a tune required? I plan for tuning with hptuners in the future after I break it in for a few hundred miles and save up. Thanks!
@@wht240sxka The L59 is essentially the same block as the LM7 you have now. My motor was changed to the different timing cover, but the LY5 is a gen iv motor and I'm using the stock reluctor wheel. The cam doesn't care which wheel you use as long as the cam position sensor and tune match the wheel. Yes you will need to tune it before you run it very far as the cam is very different from the stock cam. I wouldn't drive it without tuning it first. It will make less torque down low then the stock cam, but it makes a lot more top end power. You will also want to upgrade the springs in the heads as this cam is really designed to run over 6k rpm. I have my redline cutoff set at 6500, but it would pull to 7k and beyond if I let it. The stock truck valve springs are not designed to handle the higher rpms.
The smaller cam has a tighter LSA so that’s why the 122.5 LSA Of the LS9 cam pushes top end at expense of torque where it’s needed
And it was used along with a blower
The thing holding back the LS9 cam is the 122.5 LSA. Change the LSA to 107-109 range and YEE-HAW! Then it would be an amazing factory cam.
IT WON'T IDLE
@@richardholdener1727 Then why does the Truck Norris cam with 107 lsa work so well?
the Truck Norris isn't just a 107 lsa-it has valve events that allow it to do the things it does (after much design and testing). Those who focus on 1 aspect of the cam-are missing the big picture.
The LS9 Cam definitely has it's place as a (free to $99) cheap and effective option. Prior to becoming completely obsessed with building a big CID High Compression DI N/A GenV, I had considered another route for a specific SWAP application and the LS9 Cam made complete sense. I had planned to do a factory 5spd 2WD Colorado LSA Supercharged 4.8L LS Swap, as no one wants them, and rebuild with an LS1/6 Overbore from 4.8L to 5.1L since I would be buying pistons/rods anyway. The LS9 Cam would have been far more than enough to satisfy the breathing needs of the setup, while keeping the bottom end soft enough in a light vehicle to not be an axle breaker/tire chatter/trans breaking machine, still having a good top end and overall drivability.
how's the LT build going?
@@veganjoy Terrible. Canadian money is worth about as much as Mexican vs the US Dollar at the moment and I am still trying to find an engine builder that I am comfortable with to save me from ordering from the USA and paying a ton for shipping. If this was an LS, I wouldn't be so concerned, but I need someone who has experience with LT's and more than just CAM swaps.
@@joeyjojojr.shabadoo915 damn that's unfortunate. what shops in the US would be good with LTs? i know RPM in delaware has a kickass h/c/i package for LT1s but dunno if that translates to good knowledge for a higher displacement block
@@veganjoy MAST and LME are on my radar. My plans are very basic, but I have only seen Aluminum LT blocks sleeved out to 4.125" and I was hoping for 4.185" and do a 454 standard deck height LT and just order the 454r LS Rotating Assembly from GM Perf Parts and call it a day. Nothing fancy, just 12.0:1 on Pump Gas and use LT4 Injectors (as it's only going to be N/A). Not even sure if it's worth going aftermarket LT heads vs simply porting LT1 heads. My biggest concern is the Oil system. The variable vane LT pumps kinda scares me. Alternatively I could just use OEM GM parts and do an LT1 Corvette Dry Sump setup. I just don't want it to cost more for an N/A setup than it would have to just build a 427cu LT1 and turbo it.
@@veganjoy Take a look at American Heritage Performance out of Los Angeles. They are Corvette specialists, but they build a lot of engines that get rebranded by other shops as well. I've tuned a couple of big displacement LT setups from them that produced well over 1000 whp on E85 with a 2650 blower. I think they have a feature coming up on Engine Masters soon too.
I am enjoying the "aggressive" version of BTR LSA/LS9 cam...
I have a ls9 cam I want to try it with nitrous 170 shot
Its a good cam for the I should I change it for better one
Awesome videos, love the content. Have you done any videos regarding bore vs stroke and comparison of what’s better and pros/cons with each?
Displacement is the big thing-how you get it is a little thing
@@richardholdener1727 do you think the ls9 cam would work out good for a 5.7 ls1 with 243 heads and bigger injectors and bigger intake/throttle body?
@@germancantu9847 in the video, he said he never recommends it. So.
@@richardholdener1727is it possible to make 500 hp with a 5.3 na I have a 96 Chevy 1500 I wanna swap I have no experience with mods 6.0 to pricey in my area about double the price of a 5.3 what mods do you recommend me? That will still make it reliable daily driver, decent power
It would be interesting to see the difference between the ls9 cam and the lingenfelter gt-11 cam.
We wanna see the Converter Killer vs Truck Norris!! 😁
Love the channel. Need to talk to you about the 3800 heads. I have a porter.
call me
Funny, we just did a "Best Factory" Cam video on our YT channel, but we specialize in Honda Big Block (J-Series V6 engines 😂🤷♂️). They are very small from Factory, hence our stage 2's gain around 13-15% of power (25-35whp, we picked up 36whp in our little J32A3 3.2L NA)
This guy local to me threw a 3800 blower on a j swap in an eg hatch was nutz
It would be a good budget Hard Tire cam
Is there a video on what to do with the computers on an engine swap? I am 100% confident in all the mechanical aspects of building a motor. But I have no idea what to do with the computer after the engine is built so it holds me back 100%
Richard i think all will agree. Most Underrated Channel Going you should have at minimum half a Mill Subs, I only knew enough to get myself in trouble until i stumbled onto you looking to see if i could find out minimal knowledge of camshafts so the Mechanics doing the CAM on my 2012 HOLDEN VE SS Zseries Manual L77 6.0L (LS2 and the three other variants L76. L77, L98) thanks to you and this channel i know the ins and outs of everything now....... PLEASE SOMEHOW CAN YOU TRY SOME OF THE AUSTRLIAN LS1,2 AND 3 WITH SOME AUSTRALIAN PERFORMANCE PARTS OR TRY THEM IN THE AMERICAN LS'S........
what is different about the aussie parts?
Advancing the LS9 cam on the 5.3 would be perfect.
please see the ls9 advance video
Are you ever going to make more 5.7 hemi videos? I love how in depth your videos were, and there’s not really much video evidence of these cars pushing big numbers with all the stats to back it up like your videos did. Also, I’m looking at the on3 oil-less twin turbo kit; do you happen to have any thoughts on an oil-less turbo? love the vids, keep it up.
He's addressed this previously. They're still too expensive in the salvage yards, BUT, If someone wants to drop one off to him, he'll gladly put it through its paces.
@@genemounce8302 thanks for the info! Cant say I’m dropping mine off haha
An oil-less turbo can be a temporary turbo...
Turbos will tend to quickly destroy the self-contained oil because of the extreme heat in operation- read: tend to. A lot of attention to operating parameters will be required.
Sadly read the same. Heard if you go with billet compressor wheels it helps, but it’s damn hard to find a budget friendly turbo kit for the challys, unfortunately.
I got an engine recommendation you should try I've never seen it happen is a 305 V6 with a turbo
You need to run the SDPC Ls6 power max and Ls6 power max plus and the asa cam
Richard, I love your videos. Can you do a 351w gt40p head combo video. I am considering this setup for my 91 bronco, vs rebuilding 302 with gt40p heads. Just looking at different options. My goal is 350hp. Is this possible with these two setups?
go 351W
Richard! I watched your LSA video recently which made me think about how I'd love to see you shake up the Cam manufacturer cam card meta and test out David Vizard's calculations on how to pick a cam shaft based off of your engine components. What do you think about his methods?
David is a good guy-I speak to him often-he is doing a ported 2.2l dodge turbo head for me
I used David V' calculations on my pump gas 461. I called Isky and they cut me one real close to my original, but with a 104 center. More power everywhere!
@@richardholdener1727 I'm sorry for contacting you get but I didn't know how to otherwise. Have you ever tested the KAnd N stub stack and do they gain or lose
So use a dual plane edelbrock with a carb and gain back some of the low end and it might not be too bad for the street 🤷🏻♂️
Whip it good!
I'd like to know more about the destroked 5.3. I've got an almost brand new aluminum 5.3. I'm thinking of destroking the rotating assembly and building it like a 302, or 4.8..... Hmmm!
4.8 IS A DESTROKED 5.3L
I'm surprised these stock cams are not DoD cams, which do have different profiles for DoD lifters.
I think the OBVIOUS next step is to get an identical grind to the ls9 but with a 106 LSA 😁
that would move the power band down to a lower rpm right?
@@veganjoy depending on the LSA it could increase power across the board without any loss on top.
Richard, I’m curious about your thoughts as you may have come across this. It’s not related to this video, but I figured you would see this before one of your older videos.
Twincharging. I’m curious if you can make it work the same way compound turbos work. Instead of rigging it up like VW does from the factory (charger feeding turbo, feeding intake), if you rig up a centrifugal supercharger to feed a turbo, to then feed the intake manifold.
Would this have the same outcome? It seems east to get 60+ psi out of compound turbos, and I’m curious if this would work the same. Might be a good test video, as you probably have these things laying around.
why would you choose a centrifugal to feed a turbo-the centrifugal makes very little boost down low
A great video on one of the worst available cams for an LS engine haha. A 469 cam or even an ss2 would have given much better results at every RPM range with every single test.
Love the videos! Is there any combination you havnt run yet? Lol
ALWAYS MORE TO TEST AND LEARN
@@richardholdener1727 put David Vizards Cam calculations to the test! ;) There is alot of talk out there but not many videos or evidence of it actually working for LS engines :/
Would this be a good cam to put in my 2011 Chevrolet Silverado 4x4. Or what would you recommend, eliminating the dod, and the vvt.
Can you do texas speeds madd max cam? On a 5.3
I wonder what the LS9 cam would be like with a tighter LSA.
It’s been done more tq sooner but with positive displacement blowers it can make a car have no traction lol GM made it be soft in the hit since the blower makes instant tq
I view the LS9 cam as a way of GM getting the peak numbers it wanted while reducing powertrain stress (for fewer warranty issues) at lower speeds, where extra torque production from the blower setup with a better low-speed cam would have been pointless. Like, a burnout machine with extra burnout . . .
there is no EXTRA burnout-there is only burnout or no burnout..In my Yoda Voice!
@@richardholdener1727, burnout, you must . . . lay rubber, you will. lol
@richardholdener1727, you usually run these test with the Gen III motors which are normally around 9.5:1 compression. Would there be any real power gains by doing the same tests on a Gen IV motor, many of which are 9.9:1 compression? I don't know if the roughly 1/2 point increase in compression is enough to make a difference. Maybe a Gen III vs Gen IV vs Gen V (LT) test is in order if you can find three motors with similar cam specs.
4/10ths of a point is a change of roughly 1.5% in power
Any chance of a Harmonic Damper test? ATI has claims that their Damper "makes HP" and I have heard from other sources that claim to have dyno tested this theory that the ATI did show the most average HP across the graph when compared to other brands and OEM generally makes the most HP because it weighs less. This seems like an easy enough test to just swap out balancers and make a hand full of pulls. One video I saw even though the motor made 2 less HP they said the motor "sounded better" or quieter because of reduced harmonics.
WOULD BE GOOD
If you ever have too many 6.0l ls motors kicking around I'd be happy to take one off your hands for my 97 c1500 I'm trying to twin turbo 🤣
I never find those
I have a 1984 Corvette. Two turbos. I am putting on . Useing the cross fire injection. I hogged out been around 253 mph. At 6.300 hundred RPMs As is.12.03 . comp. 2.25 intake. 217 ?

I didn't shut down because I ran out of power or RPMs . 8 grand red line . I love my 1984 vett . Scary.
Hey Richard,
Wouldn’t the GM ASA cam be considered a Factory cam? Have you ever tested one?
was never offered in any production car-I have run them
Could you just degree it a bit in advance to try to bring in torque as well as power band a little earlier? Advance it say 5 or 6 digrees...when running it N/a
please see the ls9 cam advance video
Have you by chance done a test on the Howard rattler cam
NO SIR
Could you do a test share we focus on 500ft lb tq instead of 500 hp? Set a goal to do this by 4500 rpm NA on stroked 5.3l 383 pump gas daily driver.
th-cam.com/video/1X4fzLiTlAA/w-d-xo.html his 383 ls shootout does over 500 ft*lbs
I noticed that the dyno run starts at 3500 rpm. Would this cam require a higher stall torque coverter? Would it be soft at 2000 rpm as I'm driving around town?
Thoughts on blueprint engines 4 cylinder LS prototype?
hope it actually goes into production (thoughts on not using the word thoughts any more in comments)
Hey there Richard, I'm in Australia and I have stayed true to the Aussie delivered LS1 and have utilised standard crank with forged internals rings gapped to accommodate for some boost CNC 241 heads decked 40 thou and a 234/241 @.050 .608/.609 109lsa on ethanol makes great power it's a freight train from 3500 all the way to 7000
BUT I want to throw some turbo goodness at it! Start off at 7psi but ultimately end up at 13-14psi
My question is am I going to damage my engine making up a turbo kit with L98 CAST manifolds or should I flat out build my own 1 7/8 primary manifolds and kit?
This combo moves some air as it is, cheers in advance Richard!
STOCK MANIFOLDS ARE GOOD
Hey Richard I’ve been a sub for about 4 years now to your channel and congratulations on your success.. I just recently bought a Comp 54-303-11 cam which is from their LST line. I know you done tons of cam videos and I’m sure I’ve seen them all multiple times but was wondering if you could do a test with the LST line vs. more aggressive ramp rate cams and comparable size. I Also have AFR 215 heads and a Fast 102 with matching TB. Would be awesome bro. Just a thought or question rather. Thanks for awesome content for gear heads like us 👍🇺🇸
THE LST STUFF WORKS WELL
Does the ls9 cam have any specs specifically for positive displacement blowers? Moreso than bigger cam shifts power to a higher rpm while sacrifices down low.
yes-the valve evens and very wide lsa is how most of the pd blower cams are ground
We need more cleveland engines
Hey richard…have 2 questions, im rebuilding my 6.0L LQ4 in my 06 yukon denali and using the BTR truck norris cam…can you use pistons from a LQ9 in a LQ4 to get a little more compression? I just want to verify that you can, and would i need to upgrade the stock fuel injectors to bigger ones? And is the stock 78MM throttle body enough to feed everything properly/efficiently or would you recomend upgrading the throttle body?? Any tips you can give to help to make my daily a NICE daily is appreciated.
YOU WILL NEED A TUNE AND BIGGER INJ
no live anymore? whats going on? is everything ok?
Hey Richard i have a 6.0 in my Cadillac Cts-v what would be a great set uo to achieve 1000hp -1200 hp? Id highly appreciate if you could give me some advice just got into ls family use to be into honda’s made 700 hp on a stock block k20/24. With a turbo
please see the many 6.0l vids up that show combos to choose from. a 6.0l with a cam and turbo will do that
Any 7000, 7500, 8000rpm peak power combos ? Most always seem to be circa 6500rpm or less.
YES ON 8000
Hey Richard, I’ve got a bone stock LM7 mated w/ a 4L60E in 2000 Silverado. I’ve been watching your videos for a while and have come to trust your extensive research. In my truck everything’s 100% stock.
I have heard that the transmission can only hold 600ish HP. That being said I assume if I make 600 crank HP that it would be close to 500 wheel? (That’s what I’d like to have)
If that’s the case, i really want to work my truck up to 600 crank HP. My problem doing so, is I want to do it in steps on a budget as I learn more about engine building.
What upgrades would you recommend starting with? Could you give me a brief breakdown on cheap, easy and gains I ‘could’ expect?
I thought cheap turbo but I’m scared it’ll make too much boost and destroy my stock trans (if you have a video that explains this could you link it to me please sir?)
Thank you
I also want to add that the different variations between the LS blocks and heads is confusing to me. It sounds like I can use 6.0 heads on a 5.3…?
your 4l60e wont take 600 hp
Okay fair enough, rather know that now than find out the hard way.
What kind of power upgrades would you recommend for my setup? Also curious if you know what power the 4L60E is capable of handling.
Thank you!
Crazy wide lobe centers, 122.5!
no torque
@@NTRGFX , the dyno numbers don't look bad. To me, 106 is narrow, 114 is wide, and 122.5 is extreme.
That's a blower cam for you.
@@NTRGFX you don't gotta worry about torque with a positive displacement blower which is why it is the way it is.
Will a cam and injector change be ok with stock ls6 heads?
YES
Ls9 and ls7 cams have extremely similar specs .
What fuel are you using in all of your tests ? I hope 93 octane gasoline and not E85...
various with tests
Is lobe separation angle important?
everything is important
This may be stupid but how many horses would a destroked 6.2 with a ls9 cam and 4.8 crank make. To even better that with a mild compression ratio like 11:1
less then just leaving it 6.2Ls
Richard how you doing man, Hey I got a 2003 5.3 truck engine. My question is what I looked up I should be fine but want to ask you Sir. I put a LS9 cam in. I used the factory style timing chain sprocket. Will that be okay ?
3-BOLT TO 3-BOLT? AND DD IT HAVE THE RIGHT X PATTERN FOR THE CAM SENSOR?
@@richardholdener1727 It's three bolt yes. Online mine looks exactly like the LS2 sprocket. I have the cover, sensor installed. Tried to fire it up awhile back it wouldn't. It's in a gutted S10. It's carbed with a 800 CFM jetted to 1000. Elderbrock Victor Jr intake, ported and polished 706 head's, big valve springs. Put a 80 mm turbo in the bed with intercooler in bed. Has a 250 adjustable NOS plated on intake. Put nos on it due to the cam being sloppy out of the hole. Iv ran nos for 23 years now on my mustang and brothers mustang. Be cool to see that 4.8 you have with the LS9 cam, turbo and 75 shot nos out of the hole. It would keep them rpms up higher for sure out of hole. Hey something to try right 👍
does it have factory eccu? if so, you need a 1x trigger wheel and will need to move the cam sensor to the new design front cover with the proper cam sensor. LS2 might be 4X
Quick question 5.3 or 6.0 for chevy obs maybe 500 hp daily street truck? With around 3k budget? Off topic I know
Obviously the 6.0L is going to be easier to get there. Just a cam, tune, and bolt-ons.
@@IndenturedSavant13 in my junkyard in bakersfield ca there's a couple 6.0 s but there's also a aluminum 5.3 from a envoy delani that's why I was asking? But thanks for the info there's a yukon xl motor waiting. ✌
I have the l33 aluminum 5.3. The truck intake manifold is good(the denali may have the newer 5.3) but you may want to upgrade for a larger throttlebody. Exhaust and cam with tune will get you that 500hp or very close. The accessories will rob some power but you'll be really close. The 6L if you don't need the weight savings is nice due to the fact that it either hadbrec port heads or can fit them. From the factory the rec port heads are just superior to the cathedral ones...ported is different but their are many great factory rec port heads that flow ported head numbers and used are cheap. It's very easy to get 500hp+ out of a 6L with mild selection of parts. And that's with good torque as well. 600hp is fairly easy to achieve on stock internals with a careful selection of parts..but you'll loose some power down low as tha trade-off. I personally stroked mine for the torque, wish I had ported the heads(799's) but upgraded everything to handle boost and 7200rpm. Good luck, personally I'd look at how much they want for each and the mileage and condition of the motor and choose from there
@@mythos000000025 I am going with the 6.0 I think the aluminum 5.3 would be cool but It would mean more work I just wanna stick with the kiss rule. But thanks for all the info really appreciated 👍 ✌
@@joseperez8769 grab the heads off the l33 and use them on the 6.0. they should be 799s. Get the exhaust port ported if you can. Grab a TBSS intake and 90mm throttle.
Have you run a BTR Stage II twin turbo cam?? If so, how did it do??
I can tell you about the stage 3 in a square headed 6.0 and it works well.
@davidreed6070 I am building a twin turbo'd 6.2L using the stage II Twin turbo cam with ported square port LS3 heads.
Just trying to get a feel on what It can do.
yes-I have run the stage 2 TT cam
@@chijiokepenny2100 I am a person who matches engine components as well as possible. The hot side of my turbos, the wheel is an 80/73 with a.91 ar. I drove the car all around na..it ran good.
To run the ls7 or ls9 cam do you have to change pushrods length?
no
@richardholdener1727 thank you uncle Richard putting in my ls7 cam tomorrow on my 6.0L caprice 🫡
I have an ls6 in my ctsv. It has CAI, full headers and exhaust. What cam and intake do I need to make 500wheel HP? I want to keep it NA. Thanks
a cam won't do that
@@richardholdener1727 What will, besides boost?
@@sjcperformanceou can stroke the LS6 to 383. Higher Compression, forged internals, big camshaft, high flowing cylinder heads.
@@sjcperformancethere’s also the use of nitrous
On the 5.3L it would be interesting to drag race both combinations. Would the extra torque down low make up for the lack of HP on top? I really have no idea which would be faster.
Well a converter would take care of that but I assume you want to race stock converter in each
More power up top wins period. You aren't in that low rpm much when racing maybe on the launch but once you pass that rpm range you never see it again through a run so the top end makes alot more difference as far as an all out wot run. On the street you spend more time in that range so you may wanna go with the one with more torque that is up to how you want your powerband but as far as which one would be quicker in an all out run the one with more top end is gonna pull.
So if I put an upgrade cam on my 2005 stock Silverado I would get more power??? Horses
yes
@@richardholdener1727 thank you sir. Good videos!
Whats the peak power rpm on supercharged with the ls9?
power curve was provided
@@richardholdener1727 i see the graph but cant spot it is it 6600?
Who wants a LS9 cam now ? I have one in Sedalia Mo. for $20 with GM parts tube .
I'll take it. Message me
The answer is to run 5000 stall with the LS9 cam ;)
man forgot to turn caps lock off or something 🤣🤣🤣
NO
LS9 cam on ly76??
the ls9 cam can be run on any ls
LS3 block? LS3 ENGINE YO!! No matter the crank.. Lol
1st
Personally I blame squirrels....
The LS3 hot cam the comes in the LS3 495 horsepower crate engine is simular to the LS9 except lobe separation LS9 122 LS3 hot cam 112 peak numbers seem to be somewhat close l think the hot cam makes more low speed torque sooner and carries out slightly better over 6000rpm than the LS9 cam does but it's not a factory cam it's a performance cam made at GM performance duration numbers on these two camshaft are not exact but simular and the LS9 camshaft has a little more lift than the LS3 hot cam does and as you tested before lift has very little to do with making more power unless it's over .075 or more and it only wirth a maybe 5 horsepower upping duration is much more effective in making more horsepower than lift does seen your video on the truck Norris truck cam low lift version NSR cam vs high lift version that requires upgrades valve springs there was no power difference to speak of
What ever happened to porting factory heads and low buck hp tips? Seems like it's become "throw money till it works"... Not very realistic in today's economy.
the ls9 is a low buck factory cam-where is the money throwing
@@richardholdener1727 I mean in general... This video reminded me.
Used to be an every engine channel. Now its just LS content. Good way to loose your Ford and Mopar fan base. Even the old school GM fan base too. Shame
If only you looked at the many, many playlists on the other engine families before making this silly comment
I was told bye Benny hill's mechanic . Duration the is what you want alot of . Lift just wears out your heads . My head's say they start flowing best after 528 lift . At 28 degree timing.
The LS 9 is supposed to get 35 miles to a gallon . The dir. At 220 I understand. But the lift at over 600 left how?
Is there a video on what to do with the computers on an engine swap? I am 100% confident in all the mechanical aspects of building a motor. But I have no idea what to do with the computer after the engine is built so it holds me back 100%
I DON'T EALLY DO SWAPS-CHECK OUT SLOPPY MECHANICS FOR THAT
@Richard Holdener okay thank you, it's not really a swap it's just taking a 5.3l engine that's currently in the truck and building it up for power
do you have hp tuners or some ability to tune the new combo?
