As an avid LS enthusiast and an LS guru/tuner... THIS IS GREAT INFO! you did amazing laying the info out in a very easy to understand way!!
Do you know any holley lo-ram intake manifolds that fit the truck engines? I have a 2002 4.8 and trying to avoid adapters.
When I did my LS swap on my Chevy OBS I put together a spreadsheet showing the pros and cons in cost of moving to the LS vs a 350. Even though I probably could have put a 350 in a little cheaper I am so glad I went LS. It is so much more powerful than the old TBI 350. Thank you for putting this kind of information together to educate people to make the most informed choices.
You should do transmission next if possible bc I'm thinking of upgrading from a 4L60 to a 6L80 with an aftermarket ecu to control the transmission
In what Vehicle?, Id like to have a 6L90 in my 2007 Classic Silverado (Late 2005-2006 Style) mounted up to the Iron Block LS1 (5.3 Bored to 5.7L) using an adapter to work with the stock computer
@shadowopsairman1583 in my 2001 chevy tahoe I want to modernized my car a bit and rebuild my LM7 in it with newer piston and rods
Built level 4 6L80 is hard to tune ask me how I know
For the cost I'd rather manual swap to a t56
@RAWRMotorsports I mean yeah but I don't want to manual swap a 2001 tahoe I still want the convince of an auto
This is something I can’t wait to start supporting. Thank you for all of this.
wow, man, you're killing it lately!! This is so awesome! Love the layouts
Thanks I really appreciate the detail you put into your videos.
Amazing amount of research you did here! Good job!
These videos are PERFECT to watch while having lunch
Wow, thanks so much for putting this all together. This is going to save me a lot of time with my upcoming conversion
Bro, love all these LS videos! Thanks for sharing.
Great video. Thanks for the work and sharing the knowledge
Wow, what a great resource, thanks for your efforts, and for sharing so much! Excuse me if you have thought of this, but it may be useful to include a side profile image like the one at 13:20 to document the intake position. I haven't looked at the book yet and it won't surprise me if you have already done that. Thanks again for all your great content.
Keep the uploads going
First video I've seen from you and it earned my sub.
I absolutely love these. It would be cool to see all the mopar/he i and ford/modular stuff. Really though keep doing whatever you want to be doing, because eveything you do is gold🎉
Love this type of videos as someone who wants to Ls swap
i bet these take lots of time and effort, but it would be fenomenal to have a guide like this to the ford modular engines!. Anyway, great content as always! love from brazil
Great stuff. as usual
Good job you packed a lot of information in a short video
im thinking about ls swap my little truck in the future and just came across your videos they are amazing
Great information. Im buying the ls swap guide when its ready
You can pre-order the eBook now for free at my website!
As always, thank you for the content. Will hopefully LS swap my Z32 one of these days
My 68 Camaro is sitting in the garage with no engine, sold my old 327 that was so tired. Im researching LS and planning my swap as I do these videos.
Great video!!
So helpful thank you!
Great information
Hi, I think you are making excellent books and videos.
This information is going to come in real handy when I swap an LS into an S10. I plan to buy your ebook ASAP but I need to get a new iPhone first because my old one is out of memory.
Where u been all my life 😄 YOU'RE AMAZING MEN
Great video
Thanks !! 😀
Good stuff 👍
There was 2 cathedral port intakes you left off, but I can understand why since they were both limited production. You had the 05 Trailblazer/Envoy/SSR intake which was like the gen 3 truck intake, but used a 4 bolt throttle body, and the ls4 fwd 5.3l car intake.
Your LS swap guide is like the PC part picker for ls.
As an LS dude this makes my brain tingle haha
Got an Express cargo van with a lil 293 LS in it. TBSS intake, 799 heads..... Time to weld some headers , bungs and throw in a BTR cam w/ a 6L90e convertor in it. Already got a cooler and bypassed the trans stat. May even do a 76mm on undermount.
For any 4.8l LR4 lovers/users out there:
If you have the clearance by which to do so, highly recommend getting the TBSS 5.3l cathedral port intake if it will fit under your hood (truck guys, don't worry about this. It'll be fine.) After testing this back to back with a stock truck intake, I noticed some marked gains and have some real-world numbers to work with.
Setup: 1. 4.8l LR4 sourced from 2003 Tahoe.
2. Stage 1 ported 706/862 cylinder heads from Total Engine Airflow (part number TEA-OEM5.3ST1-CUSTOM if you're curious about the specs, although different valve springs were ultimately used) side note; as far as I'm aware, the only difference between 706 and 862 head castings were the methods used to cast them. Otherwise they are identical.
3. Summit Racing Pro LS stage 2 truck cam P/N SUM-8701R1 (.522"/.524", 218/227 @.050", 112 LSA
4. Mahle 3.830" head gaskets, .051" compressed thickness
5. Summit Racing Pro LS domed pistons P/N SUM-2999273810-2 (chosen because it had the correct wrist pin diameter) -> static compression ratio 9.83:1
6. Holley 92mm 4-bolt cable-actuated throttle body.
7. (x8) de-capped EV6 injectors (stock flow 30 lb/hr)
8. stock LS1 corvette manifolds ported only to remove harsh transitions and 90 degree corners.
9. modified 2002 Camaro SS ECU and wiring harness (modified only to fit the EV6 injectors onto the new harness.
Running them directly back to back (WOT) shows that torque production at or below 4,700 RPM is virtually identical, with small 1's and 2's popping up where the different resonant tuning of each manifold comes into effect and then falls out. Between 4,800 and 5,800 I observed an average torque gain of ~8 lb-ft, with the difference growing the higher the RPM goes. From 5,800 to 7,000 average torque production increased to ~10 lb-ft with the only time the difference being less was at and beyond 6,800 RPM.
Disclaimers: oil pan used was a Speed Engineering Camaro SS swap pan, with a stock windage tray worked over to have sharper leading edges. Oil used was Mobil-1 5W-30 full-synthetic, 6 quarts. Idle oil pressure (normal operating temperature) - 28 PSI; redline oil pressure - 78 PSI. Stock water pump from 2006 Trailblazer SS used. Engine ran in mostly stock configuration (alternator, P/S pump, water pump). Peak numbers: 368 lb-ft @5,300 - 387 HP @ 6,700 RPM.
Do with this information what you will.
Interesting! What's all involved in the conversion and is the stock trans able to deal with that torque and hp?
❤
Would love to see a video of how to install a TBSS intake on a 03-07.5 truck.
The l98 intake was also on the 2005-2006 lh6 5.3 in gmt360 trailblazer/envoy
Awesome video. What kind of gains would we see on a basic bolt on 5.3 truck when using the TBSS intake ? +15hp/+15tq?
Leaving that TBSS intake on my 5.3 that I put in my Iroc camaro. Hood doesn't close so I'll either cut in some space or put a cowl. You can easily find a TBSS in a junk yard
Important to add when going FI or even a fuel pump larger than 380 you can still use the returnless fuel rail upto 900hp. Just have to run two lines from the tank/sending unit all the way upto the back of the fuel rail, run a T a few inches away from the back of the fuel rail for the fuel pump feed in, and out to fuel rail and out of the side port to adjustable fuel pressure regulator, then from the bottom outlet on fpr to return to the tank.
The corvette filter/fpr wont keep up pressure wise once FI is added and with the return so close to the tank you would be unnecessarily heating your fuel.
great info. question, if you swap a truck manifold with a drive by cable throttle body to a TBSS manifold. witch DBC 90 mm throttle body do you advise? I hear that the 90 mm DBC throttle body's are difficult to tune? ( idle ). i installed a TBSS wit a adapter plate and the 75 mm DBC throttle body because my tuner told me the 90 mm are expensive, and the cheap one's are difficult to tune the idle. But i want the 90 mm because the more air you can get in, the more power?
Just to add to what you’ve already stated, DBW throttle bodies were added to some trucks early on, such as the Denali Truck/SUV 6.0L in 2001, Escalade 6.0L in 2002, as well as the 8.1L trucks. These early truck DBW 3-bolt throttle bodies had the same appearance motor as the Corvette, just on the opposite side of the throttle body.
10 out of 10 on video
Good info. I stuck with the stock tall truck intake on my LQ9. Why would I care what it looks like? Go trumps Show. It sure is a tight squeeze though.
W post
can you do whipples on fords, 5.0, 6.2 so on so forth? which on really produces more torque boosted?
The LS design is like taking a small block to the new level of dependable HP power
I have a fresh built 6.0 with the btr truck Norris cam and trunnion bearing upgrade and a built 4l80 with circle D converter. It’s in a 2007 one ton gmc van. It has the factory intake is there an intake or upgrade that works good with this combination? I tow with it daily and play with these loud exhaust boys.
If I replaced the early truck intake with the TBSS intake, would I need to re-tune my ecm?
I want the tbss intake, I don't think it will fit but, will a body lift work? If I raise my body high enough will it give me the space that I need?
Can you do this but for coyotes or 4.6 engines pls
This is absolutely amazing. Thank you. I have a 71 chevelle with a 5.3 truck motor and intake. But I want to switch to that TBSS intake. What injectors would I use for this tbss intake?
Check out the links in the description in my video, its expensive tho to buy the intake with the fuel rails and injectors, like $700. But you can find it for less on ebay.
I have a 2007 Chevrolet Silverado 1500 classic 4.8 crew cab any suggestions i don't want it to powerful
Holy guacamole you've just gained a subscriber on this one, this is a lot of research bundled into one video, juuiiccyyyyy. Anyone whose into engines or especially LS engines should watch this mofo
Also add that car intakes are better for nitrous and methanol distribution as truck intakes pull from one chamber look at one cut in half
Your missing The L96 that went through 2019 in the 2500 and 3500 series trucks. Also, the Dorman manifold is cheap, low profile, available from any Autozone, Oriellys or Advanced parts stores and offers the same performance as the TBSS manifold.
Can you please do a video on engine rpm. Like what you need to do to get a small block Chevy to Rev to 7,000 instead of 5,600. And how do you figure out how high the engine can rev
That is a good idea, I love high revving engines! Ill add that to the list.
When are you going to do a video with the LT6 vs VooDoo 5.2?
Thats a good idea!
Heard 13+ intakes are great on a gen 3 and cheap to find .
3:40 TBSS is the same intake as a NNBS intake
A couple of corrections: the 2005 MY Corvette which came with the LS2 is a C6, not a C5. Additionally, only the 1997/98 MY Corvettes came with a return style fuel system - from 1999 onwards it was returnless, so that started much earlier than suggested in the video (for the Corvettes specifically).
Ah good catch, C5 is 97-04? I think. I have C5 brakes on my 68 Camaro! Sometimes there is just so much info in these videos i get all turned around. : )
@@AutoGuild Yep, 97-04 is C5
Return style fuel systems make more power than a return-less system, if you have the money to do a return system then do it.
My fuel pump has the regulator and filter built into the pump, it is why it costs so much. 2007 Classic Silverado
I have a 5.3 out of my 04 Suburban. My question is, what should I do to get to 450-500hp? Please provide a detailed list so I can move forward
Cam and valve springs could add as much as 50hp, start with that. Its the best bang for buck.
Anybody know if the TBSS will fit under the hood of a Ls1 camaro?
If I remember correctly from my research it will not fit.
Did I miss the LS4 ? I own the LS4 (Monte Carlo) and don't recall a single nod...
Do the books you advertise offer LS4 info... or skip it too ?
No info on LS4 sorry : ( I know the intake is unique and Im not sure if the others will fit.
@@AutoGuild thanks for replying. Yeah I'm wanting same info with LS4 intake swaps... Can't find much info besides they're interchangeable LS3, Trailblazer and/or truck intake. Maybe your the guy to make a video
LS4 intake is the worst performing stock intake
*( Could anyone help me with a link or info on how to ditch the small 78 mm LS Truck Throttle body, and upgrade it to a stock GM TBSS 90mm, or a stock GM LS3 or newer/bigger? Everyone seem to have issues when going bigger, even having the proper 8 pin to 6 pin Summit Racing harness adapter for some reason. My heads & cam 2005 Tahoe with a TVS1900 Magnuson, is maxing out at 515 to the tires, being held back partly by the tiny 78mm stock TB. Thanks in advance for the help. )*
RUclips wont allow links in comments. Google "how to swap to a TBSS intake". There are some good videos.
@@AutoGuild @AutoGuild greatly appreciated Sir! I finally found the info I needed, bought an new ACDelco original Gold Blade from Summit Racing, and the 8 pin to 6 pin harness also from them. Will install it this weekend and will fine tune it at Moe's Speedshop in Dallas GA the week after. Have a fantastic weekend Sir!
I just want to swap my 97 L31 vortec intake out for a LS style one to eliminate the damn spider injectors
3:10 think you meant to say c6
Should i swap from early truck and TB to TBSS intake and TB or not worth it ? 🤔
Unless your engine is modified I say not worth it. Do a cam and valve spring swap first.
@AutoGuild it's a 11:1 LQ9 with 218/224@.050 110 lsa ported heads FBO x pipe dual 3" exhaust
Best intake for an lq9 on a very trackable non daily street car? 😅😅😅😅😂
Why do you need my physical address to send an e-book?
PS: Good info.
I dont, not sure why it asked for personal address. I'll see if I can correct that. Thanks
You have left one of the factory installed cathedral port intakes off of the list.
The LS4.
Just because it's bad should not disqualify it from being represented here.
Yeah I tend to not talk about the LS4 since most of my viewers are not into that engine but I will add it to my future videos. I do talk about it also in my upcoming eBook.
@@AutoGuild I was hoping to see what horsepower numbers it would get. I realize it's the worst performer but what are the numbers, how bad is it? I recently found a freshly rebuilt set of 243's on an LS4 in the Pull-it-yard and graphed the intake "just for fun". Some plastic welding might help with the airflow bottleneck, and they are *low* profile.
Forgot about the LS4 car intake for cathedral port.
The worst of them all!
MSD Atomic intake is the best 🫡
*Promosm* 🤘
You missed the actual worst LS intake and threw undeserved shade on the ls1 intake.
The worst intake is the LS4 by far.
This video is very disappointing because there's a lot of information in here. That isn't quite accurate and there's a lot of things in here that are , just straight up false. Some of the advice in here is decent , but most of it is really not. For instance, a returnless fuel system is going to leave your fuel a lot hotter, which does increase detonation. having your fuel system on a return loop to the tank keeps the fuel that is on top of your injectors at a much lower temp.
Richard holdener has already shown that the factory rec port intakes make the same exact power on a dyno. He's also done a multitude of intake manifold tests for both cathedral and rectangular port heads, showing that there are intake manifolds out there that gain power in other places. Aside from just the high rpm. F.a.s.t lsxr manifold is a great example! No low speed loss.
I might be wrong about this one. But I have never in my life seen an LS engine equipped car that came with pwm controlled fuel pump.
That's as far as I made it into the video before deciding. I should probably point out the inaccuracies in this video. I hope in the future. You make further efforts to not put out false information period.

For instance, a returnless fuel system is going to leave your fuel a lot hotter, which does increase detonation. having your fuel system on a return loop to the tank keeps the fuel that is on top of your injectors at a much lower temp. --AG: All modern GM engines are returnless now, so it apparently works fine.

He has many videos saying that too.
3) I have never in my life seen an LS engine equipped car that came with pwm controlled fuel pump. --AG: Not LS, new LT has that, todays trucks and SUVs.
@@AutoGuild Richard holder has done many tests with the lm7 to test cathedral Port intakes. Aside from that the smaller engines just gain less from the better flowing intake.
Yes GM does not have return lines anymore probably to cut costs like you said in your video. However that doesn't make it suddenly more efficient to run hot fuel than it does to run cold fuel. Use your common sense and understand that returnless is a downgrade from having a return system.
Nice one!
You Rt on some things. I've owned 7 3 -5th gens LS base cars since age 17. On the performance side I was the 1st in the southern region and my state to put a full weight true stock tq arm suspension small LS base gen 3 Camaro in the 80s . 5.80s. yes as will then and now I realized the aftermarket like FAST that cost 900-1000$ or better bk then did not cm up with a original performance intake make they simply went directly off Gm already LS1, LS3, and 6 style design they only ported and came up with a little better Flow design and for HP per $ buying one the $ to HP gains didn't add up. So we would just run the Ls6 style OEM intake. But as far as the trail blazers truck style intake they will hurt your HP under curve and HP RPM ramp bad vs a car design Gm Ls intake rectangle or cathedral port styles, the cathedral port styles works better for force induction and nitrous use . The rect port styles has a total difference type air flow flow that on the Dyno with Carry HP better mid and top end. So no I disagree that the truck TBSS OEM intakes out flow nore wk better dealing with forced and nos induction type motors like we run in the grudge race world.
