- HOW TO: 500-HP L83 MODS. CAN THE GEN 5, 5.3L L83 MAKE 500 HP? WHAT MODS ARE NECESSARY TO PUSH THE POWER LIMIT OF THE ALREADY IMPRESSIVE GEN 5, 5.3L L83 UP OVER 500 HP? CHECK OUT THE RESULTS OF THIS TEST WITH THE GANG FROM BRIAN TOOLEY RACING, WHERE THEY ADDED A SIMPLE CAM AND INTAKE UPGRADE TO COAX OVER 500 HP FROM THE 5.3L (BUT CHANGES WERE NECESSARY!). CHECK OUT HOW THEY DID IT!
I was leaving work but I guess ill sit in the parking lot instead 🤣
I just watch while I drive. Is that dangerous?
Me too lol
@@GreatLakesLogger not if you prop yr phone on the windshield lol
I do this shit to
One of my fave channels. Given me a ton of knowledge to do my 5.3 build.
Finally some Gen V testing! I have one in the garage, apart at the moment.
I do too. Tryna make bout 600 hp. L86
@@Hehakaa what are you looking to do?
Thanks Richard, man that compression with direct injection is the cats meow. Can’t wait to see more testing.
Keep this series coming sir! Would love to see a video on the piston "notching" for the stage 4 camshaft!
thanks Richard, excited to see more gen V content
Yes yes yes man I’ve been waiting for you to get to genV stuff I love it
Ive been holding off on modifying my 15 sierra till you did some more l83 videos. Cant wait to see whats next
I'll watch them all..you the man
I would say definitely on the stall converter speed. most of these 5.3's are going to be in trucks. Also, it greatly helps in drivability.
Just found your channel and found it very informative. I have a 2019.5 silverado RST 5.3L 4x4 with 2" leveling kit, wide stance, and more less a wind tunnel disaster. I have been looking for a tow setup video. Last yr we pulled a 4500lb camper through the hills and several times I found that I was running 4800 rpm's (normal is 1900 @ 70mph empty) for an extended time. This truck is my daily driver so I don't need anything radical but a little more low end power would be fun. Hoping to find a DIY setup. Thanks, if you have a chance to make us truck owners a tow/haul improvement video.
Thank You been waiting for this
Your the best Richard, love the videos!!!!!!!!
Hey Richard. Love these experiments you do for the gen 5 lt1. I have a btr stage 2 cam, msd manifold and Landspeed stage 3 heads that are milled and MR James Short did my tuning and i couldn't be happier. Great guy who knows his stuff. Richard keep up the good work and these test you run.
Very cool! James is very good at his job!
How has the trans held up 2 years after??? That’s the only thing I’m worried about lol
I love this engine. Mine is currently at 197,000 miles with 5200 hours on the original motor and everything. Finally put longtubes on her at 190k and tuned. This motor loves e85 too 😂
E85 makes them motors move
Did your truck come factory with E?
@@bobbybarraza8472 yes, l83
2014 single cab 5.3 4x4, BTR Stage 2, LT4 HPFP and Injectors, LS7 lifters, 6.2 Intake and TB, Longtubes and a dumped super 10. Truck absolutely scoots. Chirps in third with 22s and a 3.42 rear end which is wild to me lmao
Did you change the low side pump?
Some L83 luv! I've got one in my 2018 GMC Sierra 1500. Really like the engine.
I have 125,000 trouble-free miles and I beat on it!!!
My swap is so nice I just broke the 6L80e at the track last weekend… it runs 13.0 all night back to back on 22” wheels!!!
Great video !!
Thanks Bro!!
Wow that sound was 🤙🏼
Man i was so excited about this engine that i immediately clicked on their link to find it so i could but it, but unfortunately they want close to 5k for this engine with no warranty at all😞 It's listed 'as is no warranty". That sucks because I'm trying to find a good powerful 5.3l engine to replace the one in my Yukon XL and i thought that I'd found the perfect set-up but the "as is" thing killed it😂
You should test the LT2 intake manifold and 95mm tb in place of that msd intake manifold. The MSD manifold is stupid expensive and at that point, boost with a Holley high ram is more desirable.
Do you flow ported heads or just hog them out and call it good? I'd like to see some videos on head comparisons
Stage 3 cam? Duration seem too low for a stage 3 cam. Is that cam phaser the same as 4th gen cam phaser? Because it looks alot like the one I took out from my car and replaced it with a compcam one.
Now I'm tempted to pull the turbo L59 (gen 3.5 5.3) out of my fox and put one of these in. I need to drop weight off of the nose since I find myself using it for autocross. Similar power, lighter weight, less heat. I've heard something about the Gen V 5.3 cranks not being machined for a pilot bushing or something. I'd need to solve that issue before I commit. I'm on Holley Terminator X so I'd just need to upgrade to the new model that runs the Gen V.
For a pushrod 2V motor. this is honestly very impressive.
You’re telling me man! I was so shocked when I got my mine and found out how quick that big B scooted being a stock 3rd row seating Yukon lol
The heads are phenomenal
Long live the pushrod V8
I have a 2015 silverado with the 5.3L 4x4, with the stage 3 or 4 how much worse is the fuel economy?
Love the content. I’d like to keep my gen V l83 around since it’s a 2016 gmc Sierra Denali with the dreaded afm. What is the best kit with the most reliable setup with a little more power but again more reliable.
Dang. I'll be happy with a stock, e85 optimal tune l83 with the afm delete. It'll be all I need!
we need more information on the l83 im thinking of doing a 383 Stroker to maximize power
we need some more Gen 4 hemi stuff!
Good Video RICHARD
my 2017 Tahoe Set P2097 Code and the Suv had a Slight Stumble Hesitation on ACCEL
Bank 1 Fuel Trim Rich
Dealer Replaced MAF and WOW Woke up the Engine .
Suv only has 55,000 km
the SUV Realy NEEDS 500 HP
the 22" Wheels are VERY HEAVY the WholeTruck is HEAVY !!!!

When will you put a turbo on the new gen v stuff? I got an lt1 6.2 im planning on pushing to 1000.
I was told for my 5.3 just put 6.2 heads and the 6.2 intake manifold and a comp cam stage 2. And i would 100hp. Great videos let me know thanks
THE 6.2L HEADS WON'T WORK ON YOUR (SMALL BORE) 5.3L
@@richardholdener1727 thanks
Right on
Thanks brother
You guys should do a build with gen 4 rods and pistons in a gen v I have a block im building and I know one other person with a l86 putting summit pro ls rod and pistons in it stock heads stock direct injectors with hold downs running port injection and e85 my buddies running a TExas speed BFD cam and everything clears but no one I know has videos about it
this was impressive but due to the need of cutting the pistons for clearance... I would rather see the results of the stage 3 cam tested this way. please keep testing the LT series. loving the info on them.
take a peak at the stage 1-4 cam test vid that just posted
You must never... and I mean NEVER sleep! 😂 thanks Richard. Seriously considering an LT swap over and LS swap now.
Mine rocks!! 125,000 hard trouble free miles!!!
Let's see you put that in the nova. Let's see some real world builds in the nova
I would love to put that engine combo in a 3rd gen f-body and go autocross racing!
100% agreed! I have a 92 camaro rs with lots of UMI parts, konis, ls1 brake upgrade, upgraded 3.73 rear, built 700r4, and a 98 350vortec pumping out 430whp. Fun car, but it would be a much superior car with an upgraded L83 with 500hp!
So with the stage 3 is it worth the money to swap intake as well? Doing budget swap with L83 into 05 RX8. Have basically new bone stock L83 w/ C6. Would like to bump a little prior to plugging it. Will definitely get the stage 3, but should I get the intake or no?
the msd will help as shown, but I will put up the L83 vs L86 intakes with the different cams
With the DI vacuum and scavenging are not required. Just flow and cylinder filling camshafts respond differently. I been running one for 2 years now in a 95 c1500 has been great
reflected waves (intake and exhaust) are still beneficial regardless of DI
@@richardholdener1727 For real question ? when you say reflected waves are you saying intake and exhaust pulsations ? Or meaning the rate at which the air speeds up and slows down ? I like to ask questions lol or is this different than I’m thinking???
How much power were you getting from varying the cam with the BTR cam? Was this all stock ECU tuning? This would be really attractive with a Holley. Supposedly those blocks are really tough, going to be VERY interested to see this run forced induction. Something with port injection on top of stockish sized DI maybe? These are DI right? Did you try changing phase of the injection at all? I believe on the DI it can be worth more than on a port injected LS? Also, REALLY enjoyed your chat with Sloppy - it was an awesome podcast!
thnx-James Short did try injector phasing and changing cam timing
Hi Richard, My name is Shreyvon and I have a technical question for you Sir. I’ve got a mild L83 build going and I was hoping to get your opinion on possible end result power gains. So far I’ve got a LT1 camshaft, LS3 lifters and trays to get rid of DOD/AFM, LT2 intake manifold and throttle body, LT4 injectors & pump, remote water pump hookups, and other supporting mods. My serpentine belt is only turning the alternator and that’s it. I’ve got an electric motor for the power steering and like I said before hookups for an electric water pump. My plan is to run E85 and drop this engine into 2,700lbs T56 car that I have waiting for it.
mid to high 400s
Is there a dynamic video for this combination?
It’s basically a race engine
I talked to a tuner who wasn’t sure of himself. Typically you’ll know! If you can’t locate a proper tuner best just go with a mild cam. These can take all day to tune I’ve been told.
Love your channel! Been watching it none stop!
I'm looking to put a better cam in my 2004 gmc sierra. LM7 5.3. What would be a good stage one kit? My truck is all stock. I wanted to change lifters too.
truck cam
A cam designed/spec'd by David Vizard with intake/exhaust specs at 194-200 @ .050 lift on 108 LSA. David Vizard's expertise is worth looking into because he says to give the engine what it wants...Not what you think it wants.
Wow....500hp on natural aspirated!!!! Great.... Hope there a boosted with twin turbo that can make 700HP!
Its a bit expensive to play with some of the newer stuff, but they make really efficient power.
A lot*
Its a great time to be a Gear Head
It’s not expensive.. if you want to make the power these engines make you would have to spend more on the older engines. End of day they are cheaper. You can get a 385 hp 6.0 for $1900 and slap it on a car and call it a day. For you to get 385 hp from a sbc 350 you’re looking at $500 for the block $2000 for a good set of heads. $800 for the complete cam kit and $400 for an intake. You ended up paying more to make same power with sbc.
@@Miguelspl150 Not always true. I can source complete small blocks for much cheaper than that price but at the same time, I can source a 6.0 for about the same price. You cant get a 6.0 running in a car nearly as cheap as a carbed, mechanical pumped sbc. The cost of computer components, ignition, and tuning makes for less than an affordable swap. Meanwhile, I had a 350 with a mild cam running in a Berlinetta with a couple of wires and hand tools.
@@Miguelspl150 my point was control and integration to transmissions and vehicle canbus etc
Supercharger at 5 psi?
Can you do some testing on the new LT1. Compare stock intake vs. MSD vs. LT2 intake
please watch the l83 and lt1 intake test video-BTR didn't test the LS2 yet, but did run the L86, LT1 and MSD
Sir, I love what you share. Have you done a test with a Cam Motion Titan 3 in a 6.2 LT1?
no sir
510fwhp just cam and intake is pretty good. I wonder how much more u could get from head work(530-550fwhp??) Or did they not leave much on the table for head porting with the gen v
I think there's room for a bigger intake valve. Stock valve is 49mm, if I'm remembering correctly. Should be able to fit a 50.8mm valve in.
I know this is an older video, but do you have any insight into throttle hang on Gen 5 motors, especially in front of manual transmissions? My L83 will not drop to idle when I depress the clutch.
tune problem?
Will Diablo chip add horsepower?
I have a 2016 ltz dropped a dod lifter prime time to do a dod delete and cam, what would you recommend wanna increase overall power while maintaining stock torque converter
ask the guys at BTR
How much different would you expect the results will be with the L86? Curious as I have one waiting to be installed in a Jeep!
l86 makes big power-these tests are coming too
@@richardholdener1727 Cant wait! I also acquired a 2016 Z06 supercharger, I know you love forced induction testing! Thank you so much for sharing your knowledge and expertise!
These motors love e85
Do you have to make any modifications to the fuel delivery system with the new cam or will the stock injectors still be sufficient?
JUST TUNING
Can also try lt5 cam on a l83
Currently looking at an 84 , L83 vett. The factory rating 205 hp is definitely holding me back
That isnt the engine in this video. This is a GEN V block.
Have you seen Eric wiengarter video about bore size affecting head flow? The guy definitely knows his cylinder heads and bigger bore seemed to help flow
it does help flow
Another question, what are you using to tune these?!
James Short used Haltech
Have you done any tests 383 stroker vs 5.3 LS?
a 383 SBC or 383 LS?
I would like to see a comparison between the stock gen5 and a modified gen3 or 4 that makes about the same peak power so that we can see the difference in torque and power underneath the curve.
I have that-stock vs stock and 500+ v 500+ hp-might come next
@@richardholdener1727 ok cool. I must've missed that one
What's the biggest you can use without notching the pistons? Stg3?
yes-stage 3
I picked up a low mileage L83 with low compression on #4 cylinder. I am hoping it's a DOD concern . The stage 2 camshaft seems like a good choice. Should I limit the VVT or leave it as is . I also got questions about transmission options Right now it's got 2004r 2000 stall speed 10 bolt differential 305 gears . Lots of questions. As to what's the best way to get it all together
And will it work. 1964 chevelle SS
talk to btr
I think my 2017 sierra z71 is a gen 5 l83 .. if so could it be done without the long tube header? Just to verify i would need the air intake and stage 3 cam so i dont have to notch the pistons and a good tuner?
ask btr about the cam fitment (p-v) and necessary springs and need for phaser limiter (and drivability of that cam)
Where's the LT2 intake?
@richardholdner are there any differences between l86/lt1? Heads ? Valves ? Chamber ? Compression ?
I DON'T THINK SO, BUT WILL HAVE TO VERIFY
PLEASE!!! Do the dodge 4.7
I have seen so many trucks dod fail and cost to fix it is crazy . 479 hp translate to 379 hp wheel or so not bad I would like to see one of these engine get dynoed like your van did to know how much loss between engine dyno and wheel dyno
Where do you get the headers
I'd be interested to see how the LT2 manifold compares to the the L83/L86/LT1/MSD manifolds.
From what I’ve heard lt2 is less torque and more top end
For the LS1 motor with a centrifugal supercharger what intake manifold would Complement it
ls6, tbss or fast all work well
You have a link for this specific MSD intake? I have a 16 Silverado 5.3 and I’m not sure I’m finding the right one.
there is only 1 for the LT I believe
L83 makes similar power as the ls1 did on your dyno which is hood with less cubic inches
Curious on the hp gains with nitrous with this setup you got going on this dyno
if you add jetting for 100 hp-it will add 100 hp
All truck injectors the same ? 3rd gen 4th gen 4.8 5.3 6.0 ?
no-they range from 21-25 lbs with flex fuel being 33-36 pounds
I remember I saw these heads at LS fest and it dwarfed the cathedral and even square port heads, just a matter of time gen 5 takes over LT the world ? Lol
The gen 5 Lt1 style heads will outflow ls7 heads
you got numbers?
big boy ls3/ls7 heads are doing 230+cfm by ..300", 300cfm by .400" and 340 or so by .500". Peak flow of 360 to 420 cfm.
My intro on the LT show numbers a ls3 can beat but recently someone showed me otherwise.
SEX-E. Almost 100hp/L. I'm interested to see how you add more fuel for FI considering it's DI. That stuff is EXPENSIVE. On the Taurus SHO, a larger set of DI injectors and a DI pump will cost you upwards of $1,500. And that's with only 6 cylinders. At least with the newer dual-mode Ecoboost engines, you can add more fuel with the port injectors.
For us with di, fueling can be expensive. Our next step with out going aftermarket brand is lt4 hpfp and lt4 injectors. Which is 2-3k the. There is lingenfelter big bore pump if I remember correctly pump alone was 4K or we can add port fuel like ford 5.0 for about 4K but it can be hell to tune in. But our stock fuel system which is the same as the 6.2 can handle 500-600 depending on tuner..an pump or e-85
I have a L83 I’m trying to install in 1970 cutlass is there anyway you can recommend me some one to get a swap kit form
not sure on swap kits
Yukon 5.3 v8 2008 with zr1 cam What would you installing cold air intake +long tube headers or short tube headers?
Thanks a lot uncle

Let me start off by saying I am definitely a Chevy Fan. but I respect all makes right now rocking Ford gen 3 Coyote can go well over 500 hp with less work and less displacement
Yeah but you can't compare a 2V engine to a 4V engine. Of course you are going to make more power with less displacement but more airflow and RPM.
@@button-puncher I agree with what your saying we have to compare the engines

Big Bang😩
Be honest do you use the DNA headers over the others?
DNA LT headers?
I was looking at aftermarket ported l83 heads and ported 243 heads and the cfm rating seem to be very similar. Actually GPIs ported l83 is just a hair under texas speeds cfm for 243 stage 1 head i know they do there testing differently but maybe you can cover some of that.
L83 can do 1100 whp on stock block, crank, and heads with good pistons, cam, and a turbo
@@bturner-jw8dz oh yeah for sure i was just wondering the difference in CFM from ported l83 and 243 heads because they seem to be the same, as if l83 heads dont respond as well to porting as 243s.
@@texasstreettunes1310 they respond well to porting but not as big of a gain because you start with a better head.. intake side at least stock to stock. Ex needs love with ALL LT EX PORTS
@@vortecturbo I kinda figured at the time i checked and no one had flow data from the same company but it seems the older LS heads are still just as good (in terms of flow) when both ported.

Does the variable valve timing still function with stage 3 or 4?
yes
@@richardholdener1727 Does it have to be minimized or dialed back? Also, Ive heard recently that if you add increased valve spring pressure it messes up the oil pressure within the system and then also messes up the cam rotation as there is not enough pressure to rotate the cams.
