This dude giving out so much free info. Your awesome man

This would take engine masters an entire season to cover all this content. WHILE I LOVE THAT show, i get sooo much more from you here Richard! LOVE IT!

I love that you're using the smaller, more mundane LSs. Everyone lusts after the larger ones, but the smaller ones are plentiful and plenty stout. Glad to see them being shown off a bit.

The person who disliked this video must have wasted his money on a Coyote swap

I tend to describe to my clients, "Dollar per horsepower" upgrades. If you look at the Fast intake your only getting 1 horsepower per $100. Cam and heads estimated at 2500, thats $17 dollars per HP much better return of investment. I personally only tell people to change intake as the final piece for LS upgrades, as neccessary. I also have a 4.8 in my Silverado with the 454-11 comp with a manual trans on my 4x4 daily. The 4.8 is a dog down low until the velocity comes in at 4000 RPMs, very representative of your Dyno chart, which also the same place Boost comes in (by the seat of your pants) on these motors with a Turbo. 4.8l's respond well at high rpm, but if your talking daily driver, it's my personal recommendation to always up your cubic inches and you'll be much happier cruising around town. But if your a racer with a 4000-5000 stall converter the 4.8 can work pretty good with little to no mods under extreme boost. The only thing I didnt like about this video is the compression ratio was unknown. For a future video. I would love to see a 5.3 vs 6.0 vs 408 LS stroker, all at 11.5 compression (Easily capable with flattop pistons) the 454-11 Comp Cam, and Stock vs. Fast/HighRam intake. Also maybe just a thottlebody only episode looking at a 70 vs 92 vs 105 on respective intakes without a shoehorn adapter. As a tuner I firmly believe most people shy away from compression ratios over 10:1 because of the stigma of known drivability issues with Carburetors on the street. Most people dont realize how wild you can go with an engine using EFI and how well street manners are achievable with Factory and Standalone ECU technology. I also dont have the followers on my youtube channel to warrant the cost of putting this together, so if you were to do it I would be VERY delighted to see it. And FYI, your channel is often recommended by me to my clients as a tool to help bring them closer to reality. The internet has a way of putting beer goggles on real world capabilities. Many believe because X manufacturer and Y manufacturer say they offer 50 HP upgrades, and because Joe Popular in hot rod forum said he did it, That both X and Y together absolutely has to make 100 HP cause Joe Forum did it!.....Ugh! Anyways, A ton of great stuff here! Thank you for the hard work! Thank you for disclosing your results to the world and helping to bring harmony to the fight of Internet VS. Reality! Sincerely,

seems really difficult to improve on a design that GM spent millions developing, i love seeing the stock head and intake go so far with small work

Love how you say to "open them bowls up yourself" and send it. Money savings tips. 👍👍

Awesome content, great host, great energy. Thank you! P.S. Boost them both!!

Love your channel Richard! This is the best channel on KZfaq for LS facts on different combinations for most power on engine builds and can back it up!👍

Richard you're the go to guy for all things "what if," thanks for all you do!

Love this channel! No BS ,straight to the point, precise, and energetic! Very informative, learning more everytime I hit that play button. Keep on keepin on...

Keep up the quality content, brother! As a tuner I love seeing this information from an engine building stand point!

I wish I had a tuning shop nearby with someone like yourself. Thank you very much for all this information. My 05 is getting some work soon and I needed it.

Every time I watch your videos, it makes me want to buy another LS car, then cam and tune it. Love the videos, keep them up

Thx Richard, I'm finding my self trauling through you older vids which is great

man i have learned more from watching your videos in the past few weeks since i found your channel, than i have in years of being around the performance world. awesome content

Quickly becoming one of my favorite car series. Love it

Listened to your vids 6 hours straight on drive to Zip Tie Drags. Took out ear bud.... "I know LS kung fu..." :) Thank you! Great channel.

Love all of your awesome chevy LS content. In a way I wish I hadn't discovered your channel just yet though, I had things I needed to do this year.

The little engine that could! I love the 4.8L and it being the LS underdog. Can handle good boost, can handle full bolt on parts well, etc... Now I just need a good used Gen4 4.8L to build to replace my stock shortblock with for more and reliable daily driven boost.

Thank you so much for sharing this info. I just recently picked up a 5.3 to go into my 2000 silverado 1500, so I'm definitely doing this with my engine

I've always liked watching you. Thanks for sharing your combos.

Great videos. I appreciate all the testing you post. I would love to see upgrades shown individually. It would be cool to see how the cam works with stock heads and then the difference with ported heads.

I like how you are right to the point. No blah blah. Much respect . Subscribed

Richard, Great job here in the combination test video. I too, will be reading results from the warriors out there, especially for the daily driver 5.3L as retirement does not include 1K intakes or CNC heads. After 35 years of fixing as a dealer tech, I like the longevity stories with good fuel economy using home skills, headers and maybe a cam. Just want to be able to afford to buy new britches from time to time, while still feeling the seat move under them. Plus, few weekends under the hood with the feeling I went too far. Thanks again. ASE Master Tech - Retired

1 for sure boost it ,, 2 this is great ,you are answering all my build questions and making me rethink my build . Was originally just wanting 500 hp and thinking low boost on a China turbo would get me there and still drive on the street . Wow

Man I love you. You literally have given me so many different set ups.

Wow.glad I found your channel.So much great info and so much different info.Keep up the awesome work.👍👍

I really do enjoy and appreciate your videos and builds, I reference them and your books often in my own videos. What drives me personally is budget. What can I do to maximize power per dollar spent. My current favorite combination is an Lq4 shortblock with 862 heads on top. I can take these from the junkyard for one price since "engine complete" price doesn't care how many engines you cobbled together. The cam, I base on whether or not I want a converter in the application, and the price of a converter. My truck I'm using the infamous SS2, no need for new pushrods, affordable springs allow it to run, but it really should have a converter. I'm using a 3400 rpm unit from Florida Torque Converters. My Olds Ninety Eight, same engine setup, Summit 8719 cam for even more affordable springs and the stock converter. I only use stock truck intakes because the cost of rails, crossovers, a separate regulator don't add up to the benefit of the power a TBSS would give me, in my opinion. I would very much like to see what an affordable, off the shelf cam with stock everything but the necessary springs does Vs a custom ground, high end cam with custom pushrods and everything else. I'm sure they're worth more power, but how much and at what cost?

The Richard LS Holdner Channel. No one else has the indepth info that Mr. Holdner has!! Great job, Richard, and keep on testing!! Thanks!

Man I love going back and watching these vids. So much info

I love 4.8s! In 2017 when I swapped over to turbo from nitrous in my 99 Z28 I pulled the ported and milled factory 241's and a not to aggressive nitrous grind cam from lunati, vic jr intake and 750cfm double pumper, MSD controller SBE LS1 out and went directly to a SBE 2011 4.8 oil pan only came off to swap to the f body pan all I did was put valve springs in it, I have a Huron speed single t6 kit I started out with a cast wheel s475 1.15 t6 exhaust housing, air to water intercooler, the car has a 4.10 gear th400 PTC converter and around 3400 pounds it went a best of 6.41 @ 109mph 1/8 mile stock 4.8 with pac springs 210 pound injectors on e90 and Holley efi it was almost consistent enough to bracket race lol it was pretty amazing and super impressed the best it went with the nitrous setup was 6.17 @ 115. Over the winter pulled the 4.8 went over it replaced the rod and main bearings some arp rod bolts and nice oil pump, I sent the factory 799 heads to PRC to get there most aggressive CNC porting and milled, ARP headstuds, one of LJMS off the shelf turbo cams BTR springs and trunion upgrade comp pushrods, I won a summit gift card from a raffle at my local track so I ordered one of the summit brand aluminum fabricated 102mm intake, fuel rails and throttle body and a used NX plate and meziere electric water pump I reused my 210 injectors and upgraded to a 10" ptc converter. First time at the track it eventually ended up goin 5.93 boost only no body believed it was a sbe 4.8, I loved it the best boost only et was 5.85 @ 118mph and with a 75 shot 5.67 @ 121mph it lasted a whole season and lots of street miles and other activities on the street I finally ended up bending several rods throwing more nitrous at. By the hp calculators online it was around 800 boost only and a little over 900hp on the bottle. Iv already started Rebuilding it for another project it's just getting another set of gen 4 rods and bored to 3.80+ its goin in a 94 SN95 mustang so I'm getting it as close as I can to 302ci so I can keep the 5.0 badges lol

Such good info.....enjoying the long vids and tech thanks for sharing.

I've had great luck with the Texas Speed Stage 2 Truck cams, available in .550 and .600 lift. For an everyday driver you have great low end and it pulls really strong to 6200 gaining an average claimed 55hp with the LS1 blue springs (.550 lift ver.). I just picked up a set of 5.7 pistons for my next build, that's the test I'd like to see. Take that LM7 you just tested with it's dished pistons, bore it and install a set of the flat top 5.7's to see how much power is gained with a little more displacement and compression. I think I might also install one of the Crane or Comp grinds you often use, this engine will be going in a 48 Dodge street rod and I'll be looking for a little more grunt. Thanks for the video's.

Subbed. Always on the lookout for what could be the possible elusive "best NA 5.3/6.0" setup.

Try Elgin .560/.575/.585 "sloppy" cams, with Pac 1218 springs. Decap and flow test the stock injectors. Build a hot side with stock exhaust manifolds, with a Chineseum 7875 eBay turbo and air to air intercooler. It will piss off some of the aftermarket speed part companies!

Awesome comparisons, thank you!

richard nice hard work thanks for the videos keep uploading more videos very educational

For daily driver cam, I really like the Summit Racing "Ghost" cam. I replaced the ASA cam that I had in my Cougar with the "Ghost" cam and it picked up both torque and HP. This is also a good cam if you plan to go with a turbo later. Summit Racing used to call the "Ghost" cam their Stage 1 turbo cam.

I have a 2019 Sierra 5.3 that I seriously want to get in to. All of this gets my juices flowing lol

I really like that cam selection, seems like you could run that in a car/truck and not effect drivability at all.

Hella good content. Thankyou. Enjoyed the length too

Running the BTR truck stage 2 camshaft in my wifes 5.3 Envoy with TBSS intake and stock 862 heads with spring upgrade. I have to say it's the perfect daily driver cam as it picked up alot of mid range and low end power all while keeping fuel mileage on par with the factory camshaft.

Hey Richard I thought the 706 heads wasnt that good, cuz they're prone to cracking! But now when you say you can polish and Port them for better results I think I'll stick with my 706 heads on my 5.3 thanks for the knowledge bro!👍👍✌

Thanks for this video I am getting my 4.8 05 Chevy Tahoe fixed and I wanted to add some hp too it. This really will help out with my decision!!

SUPER happy with my Brute Speed blower cam for a bolt on LS1. Even without the D1SC; it’s super drivable, great idle, and the springs last. All this while making killer peak power, while producing great numbers and response UNDER the curve. Bob Beam ftw! Honestly want to use it in a 4-point-great, with TBSS intake, and s400 in my next s10/LS build…

You should start a podcast talking to manufacturers about the parts you guys use in testing I’d listen to that all day

Best LS info on KZfaq! Can you do a video on what you look for when getting a junkyard engine and how to avoid getting a rotten egg

Is 4:30am and still binge watching 🤯🤯

Dude...seriously. Your channel should have like, tens of thousands of views.

Thanks for the content of this video was very helpful I'm in a middle of a build

Thanks Richard! I'm in the research phase for a possible 5.1 build for an autocross motor. There is a 300lb weight break at that size so it's very interesting to see real world numbers. Trying to imagine what a slightly offset ground 4.8 crank in an LS1 would make with some head work and a cam along with my existing FAST parts. Really want to see 450whp and ideally ~330wtq by 3000rpm. This video makes me think it will work with the extra 0.3L, more compression, and E85.

Even as a Mopar nut, I love the hell out of this Channel. Richard is awesome.

Daily driver setup - tbss Intake, 90mm throttle body, 1.75" headers, stock heads with a 216/220 @.050 duration cam at .550 lift with a like lsa of 109. Enough low end torque you dont need a stall converter but still have a slightly choppy idle

Home porting stock 5.3 heads ls6 cam and Tbss intake and a good tune great for daily driver worked great for me.

Great video! 🔥

Thanks for all the great info. Motor up fellas

Amazing channel, thank you!

My buddy has an aluminum 5.3 with 243heads in a c1500, running btr stage 3 truck cam, long tubes, and ls6 intake, we will be testing it out any day now

I’d love to see this again with the SS2 cam and the same home head work on the 862/706’s. It’s seems to be one of the most, if not the most common asked questions and used combinations, with almost zero real world results.

You are the best. Please don’t stop

The Texas speed cams are great! I DD a firehawk with a ls2 and a 228r cam. Made 420hp through a 4l60 and a stock 10 bolt

Absolutely love the show and the amount of content! Just wish we could hear the dyno pulls 😭

I’ve been kicking around the idea of an engine swap on my Miata. The rules for the class I want to run in limit displacement to 5.0L. So I was thinking about a big bore 4.8L / 303 CI, this video has further solidified that notion. Thanks!

Stock 5.3l engine, TBSS intake, light porting and performance valve job on 706 heads by a professional, 10:1 compression 214 dur at .050 Intake 220 at .050 exhaust 111 lobe seperation with a little bit of advance. Great torque plenty of horsepower easy to live with but lots of fun.

GREAT VIDEO RICHARD!!! I AGREE WITH YOU 100%. BOTH ARE GREAT MOTORS FOR ANY LS BUILD.

Excellent channel .. thanks for the effort that you putting in and sharing your knowledge to educate us.. I would like to see more testing on LS3 or L92 engines whit the same set up heads, camshafts, intakes, turbo and supercharged. stock bottom or upgraded. Good luck 👍

I love the channel and all the quality content. Any chance you could do a similar test on the 6.2L single overhead cam Ford and the new 7.3 pushrod Ford engines?

This is great. My project is to build a JY motor for a weekend racer with a stock manual transmission but with good HP & higher RPM's that doesn't create too much torque to blow the stock trans. Like my BMW except I want to build it with a GM LS. I think that is going to be awesome to show up with something like that.

Very Nice compare! I'm building 6.0 with #823's trying to decide if stage 2 or stage 3 BTR cam best for street/strip weekend car. Rec port guy also curious about the intake differences. Keep up the great work!! Big Fan your the man!!

Like to see 4.8L with various cams. Especially trying to make more torque

I like that they run the test and hold aftermarket company’s to be honest on what there product really does on every kind of combo, and if the stock stuff is better, and if it’s not worth the money they put it out there. Really makes the top company’s stand out! Like this test anything under 6k rpm the stock truck intake is the way to go and not worth the coin to upgrade, and even up top is it worth it depending on the combo to upgrade to say a fast intake. Thank you on the info you put out! Would love to see a test pushing the aluminum block and cast iron block to its limits. And to also see if or at what power level should you use cast iron over aluminum or does it matter? And at what power level should you upgrade to aftermarket or say a lsx block! Run them hard and tear them down and look for wear to see at what power level each block start to fail and wear out parts.

still amazes me how well these engines perform stock with just a freshen up.

Now I like this test. Hell yea!

I have a 4.8 it’s got 882 heads, mild comp cam can’t remember the lift, 6l intake manifold and a 80mm precision turbo it’s an absolute blast for a cheap build

Can you test off the shelf turbo logs on several engines and see how they stack against tubular manifolds? Where do they choke out on backpressure etc. Keep up the good vids

I'm a Ford guy, 2v Panther, but funk it I subscribed, great video bro..

This man's a Saint!

Amazing content Richard!! I would like to see the "Sloppy Stage" 1, 2, and 3 (Elgin E-1839-P, E-1840-P, and E1841-P) cams, run against the full lineup of Summit LS cams. Or at least one brand or the other, because that many cam changes would be a LOT of work. I'm running the "Sloppy Stage 3" cam in a 4.8 with a pair of china GT35s in the trunk, and it runs well. That cam seems good in Engine Analyzer also, but who really knows until Richard Holdener puts them to the test on the dyno! Haha

I feel like an LS expert just by watching this channel

A 496 stroker with a 224/236 duration cam is a pretty sweet combo😁 jk. No experience with LS engines. I am thinking about one in a s10 tough. Thanks for the videos!

With the CNC head 4.8, you would definitely need a substantially higher than stock stall rating torque converter to keep the RPM in the useful powerband during flash

Richard, myself and others would really like to see how that lsxrt intake behaves under boost. Thank you for the videos.

I love the Tick Sat night special cams, tight LSA so they sound angry at idle and a really punchy mid-range. The stg 2 is a go too for stock compression 5.3/6.0. I put a stg 3 in my buddies iron 346 with katech cnc 862's. Sounds like a drag car and will boil the tires at 40+mph.

Did a Gen IV 5.3 in a 2013 Silverado... 224/232 .581"/.595" 113 LSA cam similar to the Crane - on Comp Lobes. Texas Speed PRC Stg 2.5 heads @ 58cc (706/862 cores), stock intake, TB, etc. Cheap Speed Engineering 1.75" headers and ORY. 3" cat back exhaust. 3200 converter, 4.10 gears, heavy 20" wheel/tire combo. It made 420 rwhp/398 rwtq on 93 octane swill. My truck is a 2001 Silverado... LQ4/80E swap, EPS 214/220 .598"/604" 111 LSA, TBSS intake, 92mm TB, 1.75" headers, 2.5" down pipes, dual in/single 3.5" out Magnaflow, 4.10 gears. Going to see what it does on the same dyno Wednesday. Previously did 349/384 on 87 octane - different dyno. Swapping to a set of AI rebuilt/milled 799s (no porting), FAST LSXRT, and a 3000 converter, + 93 octane. These tests have me rethinking... maybe I need a set of 862s pretty much untouched. Keep the TBSS intake, and do the converter + retune on 93. I use my truck as a daily/tow pig. Thought I had a plan, now - not so sure.

The truck intake did better than I thought it would

Hi Rich. Great videos! Thank you :-) what about a test on a turbo motor, sizable Turbo fairly built with decent heads, then put on the best ported race heads you can find

Great video

This is amazing. I have the 4.8 in a beat up 08 Sierra. It runs well but I don’t think the truck would hold up to this kind of power!

It's more amazing that the factory intake ran a smoother power curve than the fast intake on both engines. I would rather save the money and not buy the fast intake. Thanks for making this video.

I used a stage 3 Texas speed low lift cam with 799 heads milled 0.40 with trunion kit ls7 timing chain set up ls7 lifters and high pressure oil pump 2011 Chevy Tahoe daily driver

Awesome clip.

Richard, this kinda leads into a best off the shelf cam for a NA 5.3 test, watcha think? With some 863/706 milled and some hand clean up and a dorman LS2 for car apps and a TBSS for trucks test. It'd be a great inexpensive 500+ HP street engine for sure !

I would like to see your low buck build of these two combinations.

Hi Richard, like to see stock 6.0 lq9 with L92 heads with ebay tt vs 454 tt. Keep up the great channel. I like running comp 242 cam.

What I would like to see a test done on is 4.8 with higher compression tested. Full point or more.

I'd be interested to see some testing done with different compression on a "cheap" junkyard build, 4.8/5.3, tbss intake, with a healthy 230's/240's duration cam and milling some 706/862/243 heads that have been hand ported at home to see how the compression change effects power, then try the same setup on E85. Most people here are on a budget and cant afford a set of CNC heads. I would also like to see some testing done with the TSP Torquer V2 camshaft!

Can you demonstrate the at-home porting techniques you mention in this video?

I’m surprised the truck intakes are right up there the FAST intake after the cams and porting. I got a express work truck with a 6.0L I plan on stealing the motor from when the body finishes rusting away. Great info!

Best ls man and greatest tests. If you add s400 turbo on that 5.3 i am sure you will make 1000hp by 17 psi (approx). Impressive! But what if you swap to hi ram intake and ls3 heads ?
