Just scored a L92 and 6L80E trans from the junkyard!!!!

Another note on longtubes. My ls Miata had a 5.3 with a cam and ran fine with cast iron manifolds and dual 2.5” exhaust. I switched to a 6.2 with a cam. And the car started to run much hotter. I finally did longtubes headers and dual 3” and dropped about 30 degrees in coolant temp across the board. The iron manifolds weren’t much of a restriction on the 5.3 but chocked the 6.2 out like crazy.

Your my favourite engine channel. Massive thanks for what you do Richard.

My favorite source for proven LS engine power!

Richard you keep grinding out the best content ! 👍

Amazing, thorough review on what to do, with all the dyno work to prove/validate all options... hands down best vid I have watched all year, and I watch a few! Haha... 👍👍👍

Thanks for the info. I already got my intake, I went with fast. And long tube headers. I have a 2000 Z28 and can't wait to install. Now I have a better idea of what to expect. Doing a cam swap too. Can't wait now. Thanks again. Still learning these ls motors. Too much misinformation out there. Thanks for clearing it up. I was using my old small block info to just get by.

HOLY SHIT 122hp cam swap? wow

I feel very educated after watching your video. I know exactly how to start my build in the next few months. Thank you

Protect this man at all cost!!!

Just learned a ton about the L92/LS3 in less than a half an hour, time to get started on my build...thank you!

Thank you again Richard for your great work.

Tons of good info Richard, much appreciated! Rule of thumb is to address the bottlenecks and it seems that heads and intake aren't always the biggest issue!

Always good stuff Richard.

Hey Richard I just want to thank you for doing all the hard work and educating us . I also have a question if you could do some testing on an vk56de engine I have a motor here in Fairfield. And again thank you Richard you are the Man

Thank you so much..... Loaded with really good information and I learned more then I thought I knew. Richard the engine God

Richard YOU ARE SUCH A BADASS!!! LOVE YOUR CONTENT MY MAN!! THANK YOU 😁👏🏼🙌🏼👌

WOW!! That is a lot of information!!!!!! Thank you very much.

Just simple and common sense brilliant! Thank You Very Much!🇺🇸

Great video Richard 👍🏻

This channel and information is SO YUMMY !!!! Ugh! You are saving people thousands of dollars. Your contributions to the HP world are endless. Thank you so much.

Thanks for all that you do Richard! Your making my stroker build too easy! Are you selling those "Be Prepared" shirts?

Great testing and information revealed

My L92 powered G-Body went 11.04 @ 119 on a GM performance dual plane and 10.92@ 122 on CID single plane. SBE, short travel lifters, hollow stem intake valves, 233/247 . 3280 lbs race weight. 5200 stall. No power adder, pump gas. Back to back to back 10.90's . L92 is great.

So basically stage 2 or 3 cam and all the supporting mods like long tube headers, optimize tune and keep the ls3 intake because it just works great = cheap reliable power! From there it gets very expensive going bigger displacement with higher flowing portend heads topped with a high ram intake. Bigger the air pump bigger the power. Great video as always.

Great video as always

Perfect excuse to have a big cam haha especially if you don't lose much down low.

Thanks for the l92 info! I just got one out of an 07 Escalade to put in my Chevelle, guess I’m gonna put the summit stage 4 in it and terminator x and let it roll!

This is knowledge in detail!! Thanks

Your work is priceless

Hi Richerd …… a interesting test would be a comp cam 459 cam in the L92 … then a LS3 even though there virtually identical except the pistons and VVT.. then the same cam in a 416 stroker with rec port heads.😎👍

Thanks again Richard.

Great entertainment on a cold Friday night; Richard discussing my favorite LS engine, the LS3. It's just awesome that GM made race-quality intake manifold and cylinder heads on a regular production engine. Then just add a cam that has 20 more degrees duration, and you can add 60 hp. And that's without sacrificing any torque below 3500 rpm. I've wanted to do an LS3 build for my 4th-Gen Camaro for years. LS3 stroked to 400 cubic inches with an L8T crank, 224 cam, and GMPP ported heads, long tube headers, and stock LS3 intake. Would be easily above 550 hp.

🤯 as usual when I watch a Richard Holdner video. We can't thank you enough for running all the tests we used to have to run in our heads, or either that old windows 95 Desktop Dyno program 🤣

Another one! Thanks!!

Already did this lol where was this video when I needed it haha

580 590 615 for a 376ci engine on pump gas is amazing all of these setups will work well with the right stall and rear gearing like to see some times with the 615 horsepower setup with a 4400-5000rmp stall converter with 4.10 gears in a 3500 pound car or less with a good suspension and drag radials should run 10.20s-10.50s in the quarter and with a overdrive transmission with a lockup stall converter should be streetable and cruise 70mph all day on the highway at 2400-2500rpm and what l love about this 615 horsepower setup is the 7200-7400rpm redline while still being streetable and still makes good torque at over 6000rpm and idle at 900rpm to do this with a old style smallblock chevy you'd need 12 to 1 compression AFR or some kind of expensive after market heads and a very big cam to match this kind of top end power not to mention it would probably idle around 1200-1500rpm and be a beast to drive on the street and even then bet torque drops off quickly above 5500rpm compared to a much more mild LS engine a bigger inch 406 old style smallblock can match this kind of power doubt it would rev as well or make this kind of torque in the upper rpm range as this LS engine does and the old style smallblock would need a 255 or more duration cam at over 625 lift to match this kind of power so your not going to be using a stock engine without after market pistons with valve reliefs and this power can be made using a stock LS 6.2 engine with stock crank rods and pistons wondering how much of a difference this 615 horsepower setup would loose with a Holley 4150 hp 950 and a victor jr intake or something very similar compared to this dominator never seen a dominator carb work well on the street I've seen plenty of Holley 850 and 950 hp 4150 carbs work well on the street

THANK YOU SO MUCH !!!

Awesome videos!! Could you do a video on V10 motors? I like the ram truck v10 motor. Maybe if you could compare it to the viper motor and upgrades on truck motor for more power and torque.

Man alive that cross-flow dual intake looks mean. Almost worth it just for the look.

Gonna be running an ls3 with 243 heads and ported tbss intake in my Silverado real soon so stoked !

Would’ve been interesting to see what the ported head picked up when running the 227 and 231 cam

Keep save have a good Xmas

The LS3 Intake Manifold with the "Rod Mod" from GPI or any other vendor that does it yeilds great gains over the OEM LS3 intake manifold. I picked up 17wtq on my setup alone.

Great to see the torque similarities between cam sizes. I run a 235/247 113 cam in a 6k lb truck. Drives great with the 3200 stall. Ran 8.6@82 in the 1/8th N/A.

Well heres the thing, i did test a smaller cam like you said on an l92, it did pick up power everywhere unlike what u mentioned. I am talking about an awd chassis dyno as well... Just my little piece of info i ran and tuned... Not hearsay.

great info

Good stuff

Thanks so much!

The more I watch the more I learn.

I’m just waiting on the 6.2 Big Bang!!!!! Can you make it happen?

I ran a TSP 224 cam shorty headers, k&n intake, oem cats, 3.5 straight pipe axle dump on a 08 L92 sierra denali. Oem torque converter and tune. It got up and moved

Dang, this would be so exciting except for the fact I have one of those 6.2 motors with all the rattling and tapping. Scared to do anything to it.

Great info thanks for posting, my L92 has a cold air intake, mbrp exhaust and a superchips flashpaq F5 handheld tuner and ive been wondering what the next step or upgrade should be and after watching it is undeniably going to be a camshaft for sure! Tons of tire smoke and angry people getting passed by a big heavy yukon denali on the roads hahaha

Right on

It's crazy this "stock ' motor can make so much power with just cam,springs, and long tubes

Richard, is there any way you could do an analysis of rear mount turbos? Several guys on here have shown some great success, but never a break down like you do. It's a topic heavily laden with mythology, and you seem to "bang" through all the myth with knowledge and evidence!

I do usually disagree on the cylinder head issue. Anytime I can gain power through the entire curve or in the area’s that matter I’m in. If my choice to gain another 15-20 is more camshaft and less driveability or cylinder head upgrade I’ll take the cylinder head upgrade all day. As long as the head you chose doesn’t kill all low rpm torque from an inefficient design go for it. Get the most power you can the most efficient way you can. Not every change needs to gain you 50hp and more. If I was at 480 and wanted 500 I wouldn’t do more cam if heads would get me what I wanted. On the same hand always buy the head that will work great when you upgrade cubic inches as you should always do. Great video btw. Thank you for your work Richard. This is much better than watching politics.

Great video,you have a lot of knowledge on builds.Richard I have a l92 that I’m putting in a 86 c10 with a 4l80.friend of mine has the Arun .608/.615 -230/242 -115+4 jam cam new that he’s giving me.what you think about that cam with a 78/75 billet turbo.

Had a chance to get a l92 at a local picknpull out of a 07 escalade. But really didn't have the time. Regret it dearly. I wanted it for my s10. Too many people do the 5.3. Alot do the 6.0 also but nothing like the 5.3. I want to go a diff route. I just like the idea of having a 6.2L

Ls3 ftw!!!!

OK IM DOING IT IM SWAPPING THE E92 🤘

Thank you Richard, for your videos. You're truly a Blessing. How about making a video,,,,,, of what kind of power you could make from SBC technology available pre-1977? Na of course? I'm in a club that can only use pre 1977 parts. I had a machinist friend ( far above his time ) build a 355 sbc , na with 530 hp. I've been shouted down,,,, by the " big fish in the pond ", that it was impossible to achieve 530 na in 1977 with what was available? I had a LT-1 4 bolt main, 292 " turbo" heads, fully ported that flowed 291 cfm, bla bla on the rest? 2 3/4 " Hooker tuned headers, Excell duel point, ect. Please enlighten us ALL,,, as to the possibilities of 500 plus hp, na, possible in 1977. Thank you!!!! There's thousands waiting for this one......

That all being said, great content as usual….and nothing to do with anything but I wonder, the LS3 factory intake manifold is so well designed that GM didn’t leave much on the table for improvement. Now the FAST 102mm LSXR very expensive intake doesn’t make any significant power increases compared to a stock LS3 intake…. But would there be a significant increase in HP and Torque on a bigger displacement LS3 like the common 416 stroker .

I think the L9H was the most common 6.2L truck engine

I own a 08, C6. Ls3. What is the best header, for a good price. Thanks for all the info

Would be intresting to try this engine with original outlet manifolds and turbos Just about 10psi There is à lack of high power v8 in sweden for a resonable price Would be perfekt to have a complete soulotion

gonna sell my 5.3 yukon and get the denali wit the L92, def gonna ride with power and luxury

I love your builds but you should do more builds with info on cam to torque converter. I guess I should ask the cam you ran on the L92 would you need an upgraded torque converter is that a cam you could run with factory settings and not do have to do much but maybe have the engine tuned.

On the cross ram, my guess is that the runner has some casting that needs to be cleaned up. that "low spot" in the 5500-6k range just seems off to me.

I have a 6.2 in my 08 yukon Denali, it has almost 300k miles , i want to put it in my 75 caprice with a procharger I’m debating should I rebuild it or should I just got buy a 6.2 out the crate ?

Good old pushrod technology

So with those numbers on my l9h is there any reason not to put that up in my truck?

Again, great videos. Can you or have you done a comparison between a X pipe and a H pipe while using long tube headers?

I had a 2010 sierra Denali I bought new and light to light that thing was a monster Eaton locking awd that thing would jump across the entire intersection before the guy beside you would move 😂

What Combination for a L92 Truck 6.2 for Low End Torque thru Mid Range in a Heavy 96 Land Cruiser 'Triple Locked" Swap ~ Thank You, Love Content Sir

Finna put a l92 on my 96 single cab shortbed Silverado

I enjoy all your videos. I have a 2014 SS Camaro with a 6.2 L99 with an automatic transmission, Long tube headers, cold air intake, oil catch can, and a tune. What cam would you recommend for a horsepower upgrade without having to install a torque converter.

Happy New Years Richard! I got a question, 1 3/4 vs 1 7/8 on a stock 6.2 or with a small vvt truck cam?

love this !!!......will the lower lsa help torque with the 224 cam?

Parents: Richard what do you want to be? Richard: LS GOD

I apologize if I missed it but what springs did you end up using for the summit stage 4 cam? Great video btw.

And everyone was looking at me like a crazy person when I bought my Escalade

Hey Richard, always great info! My question for you is, how grumpy are these bigger cam setups on a daily driver. I have a 37 Chevy Master looking, I'm looking at taking a 6.0, punching it out to a 6.2, building, and putting it into this car for a cruiser. I want to build it to keep the a stock converter and have good low end torque. Can I realistically do that and it have 500 hp? Can you use the E85 gas in these setups? Thank you, and keep up the awesome testing!

I have a 2017 Escalade with a 6.2L. I'm replacing my 3.23 gears with 4.56 gears, lightweight brake rotors.

Can you do a test on the new 2020 LT1 m otor.How good is the factory intake and heads?How much can you get from a cam swap?What cam do you recommend i use? Mike Dohm

I can't wait to see you do a lq4 or l92 with the new lt1 heads people are doing it but don't believe anything if its not done by Richardson Holdener

I have a question that wasn't covered. If you take a 6.2 and install 243 heads, 54-426-11 Comp cam with a Holley 650 DP Carb. what numbers are we looking at?

Hi Richard, I have an L92 that I plan to swap into my E36 weekend warrior/track car. I’d like to go with a very responsive twin turbo setup. Main limiting factors are space, weight and throttle response. Do you have any recommandations? GT28vsGT30 or s200s

Hey Richard, Do 1 7/8 long-tube headers gain noticeable more power over the 1 3/4 long-tube headers on a cammed LS3. Thought you would be the perfect guy to ask, Cheers

Would like thank you again… please i want to know if their any benefit adding a intake manifold spacer will make any additional power

Was this cam SUM-8711? Please verify, you inspired me to finally do an ls-swap with an l92. Summit now makes SUM-8711R1 instead, I hope it has the same characteristics and clearance. Thank you!

👍

Thinking about swapping in the L92/6L80 into my wife's Yukon XL. Would the power cam and a torque converter be all that's needed for a bit more oomph for towing? Not looking for big power.

What do You think about extrude porting? Also please do a video about how to identify the different LS engines in the junkyard.

What is the part number for that summit cam used in the first l92 test.

@Richard can you drop the link for your exact summit racing stage 4 cam you used in the L92, im having trouble finding it

How would I know the difference... I’ve got a 2011 Raptor.

Hi richard! I follow you from italy with my c6 ls3, here we don't have so much aftermaket variety and many shops in usa didin't sell in italy.. also the price are very expensive with shipping and taxes.. so i would like to upgrade my engine whit a good cam and a long tube, i wanna improve my hp but also i want the best reliability for my engine (here in sicily i think there are 10-15 vette in total), so can you suggest me the best mode hp/reliability? The type of cam.. thank you very much for your free info, you're the best! Happy new year ❤

Hey Richard. Have you tested the Z28 Camaro Tri-Y vs long tube headers? How much are ARH headers vs Kooks vs ebay headers?
