When it comes down to it the Gen II engines share nothing in common with the (LS based) Gen III-V engines. The SBC and the Gen II engines however have several key traits in common: Deck height, bore spacing, part interchangeability (namely rotating assembly), and basic block architecture (which is about as strong an argument as you can have). This commonality clearly demonstrates SBC's and Gen II's very close relationship and warrants the Gen II's inclusion on this page. When it comes down to it, the Gen II engines are nothing more than modified SBC engines. Now I know in the process of moving the Gen II section, I might have messed something up. I was forced to rename the LS based engines to something and all I could come up with was Gen III-V small-block (LS based GM small-block engines seems a better choice to me). There shouldn't be too much of an issue calling the Gen V engines LS based after all Deck height, bore spacing, part interchangeability (namely rotating assembly), and basic block architecture is shared with the Gen III and IV engines; the Gen V engine are not exactly clean slate designs.

The Gen II engine have mechanically nothing in common with the Gen III thru V engines. The Gen II are bacically Gen I (specifally the Gen I 305 and 350) engines that have been slightly modified to incorporate the Gen II updates; the Gen I and Gen II have similar basic block and mechanical architecture, and there is some good part interchangeability. It makes perfect sense to have the Gen III thru V grouped together beacuse their basic block and mechanical architectures are similar if not the same in many aspects, and there is some good part interchangeability. Having the Gen II on this page also goes againts the basic idea that this page and the Gen I page have: part interchangeability. you can remove the rotating assembly from a Gen II LT1 or Gen II L99 and put them into a Gen I engine with no issue. You can't take the rotating assembly of any Gen II engines and put them into a Gen III thru Gen V engine as they are 100% completely different. you take a Gen III 5.3 L crank and put it into a Gen IV or Gen V and there is not issue epesically if you update the exciter ring on the crank to the a 58x. The Gen III thru Gen V aren't exactly the same but at the same time they aren't 100% different. Gulielmi2002 ( talk) 18:40, 26 November 2014 (UTC)

I believe earlier ls6 engines were 385 horsepower. The 405 hp version came later, after the addition of lighter valves a higher lift cam and better exhaust. Will do some research and come back.-- Ultrapop1 02:10, Oct 3, 2004 (UTC)
Chevy rates the LS2 in the C6 at 400 hp @ 6000 rpm, not 405. Also, IIRC the new LS7 has been rated at 505 hp @ 6300 rpm and 470 lbs-ft @ 4800 rpm by the new SAE J2723 rating. Atleast that's according to the GM Small Block blog. I'm going to go ahead and change those.-- C-Tine 2 July 2005 17:32 (UTC)

I've just removed the reference to the Factory Five from the LS1 section - seeing as it's not a production vehicle (it's a kit car), it's about as relevant as mentioning that there are 1993 RX-7's with LS1s. Ayocee 17:29, 30 October 2005 (UTC)

One of GM's favorite things to trumpet about the new Z06 and LS7 is that it is the first engine to be certified using SAE's J2723 test. I find it highly suspect that they would trumpet this, and yet somehow manage to 'miss' 45hp. Ayocee 02:49, 9 February 2006 (UTC)
They didn't "miss" 45hp. An unladden LS7 was SAE tested, not the Z06. The engine is rated for 505hp, and 45 hp is lost throught the drivetrain. It isn't 550hp or even 505hp by the time it gets to the wheels.-- 24.89.215.104 01:52, 21 July 2006 (UTC)
An effort should be made to adopt some unit convention, either SI (english) OR english (SI). It reduces the quality of the articles if the units are constantly mixed. For example, the engine size notation ci (cc) is proper if other measurements are cited as inches (centimeters).
That's the interesting part with American engines. The engineers design and build the block with SI, but they publicly post the engine's vital stats in english. The LT and LS blocks were both designed with SI measurement and their displacements are both advertised in metric. In this case, unit conversion should stand as "SI (english)"
With that said, it's safe to say that Detroit doesn't use cubic inches anymore. Only the old guys are calling an LS7 a "427" or an LS1 a "350".-- 24.89.215.104 23:23, 4 July 2006 (UTC)
HSV's GTS didn't use the LS6. It used the LS1, that was modified by Callaway & was designated "C4B": http://autospeed.drive.com.au/cms/A_1553/article.html Aml_0000 15:30, 6 June 2006 (UTC)

I think it's worth revisiting this topic and its merits as to inclusion in Wikipedia. My previous reply above may have been worded a bit harshly in exasperation (or whatever it was) but the fact remains that even now the only 'source' available for the problem (as well as its scope and severity) appears to be a site that would arguably fall under the category of a self-published source. I'm not trying to be combative or argumentative here, either; if there's a reputable source that actually shows evidence of piston slap being a) a problem on a significant number of engines and b) a significant issue, I'd love to see it (and cite it for Wikipedia purposes).
Ayocee 21:36, 11 September 2007 (UTC)
I have a 2004 crate LS1 that i bought from Chevrolet and installed in my 2001 Camaro, the engine has Piston Slap from day one.I just let the engine warm up before i drive and BTW I added a supercharger with 8 psi boost and still no problems from it.I drag raced for over 12 years and most of the time I set the engine up loose for piston speed and almost every time had some piston slap. it's not a problem for me. Camaro guy 11:47,June 14 2012
Anyone can say they have a LS1 with pistons slap, but i can't seem to find one even in a used dealer lot with piston slap, found a 5.0L mercury & 5.0 explorer that had piston slap with only 100k miles, and that's a smaller piston. stop making stuff up, this doesn't exist real life, in larger numbers like the 5.0L in SUV's — Preceding unsigned comment added by 24.151.159.206 ( talk) 16:48, 22 April 2014 (UTC)
There are known and easily-verified differences in the details of most LS1 variants - the cam used in the Corvette is not the same cam as in the Camaro, and the camshaft specifications changed between 1997-2000 and 2001-on. While it's likely that the actual output is closer than GM would admit, there's no reason to believe that every version of LS1 ever used was actually putting down 345hp. Ayocee 20:10, 14 December 2006 (UTC)

i am in the process of reorganizing this page to have the same flow as the original small block page and the LT series page. i have included the 4.8, 5.3, and the 6.0 in this page as well. Gulielmi2002 ( talk) 20:02, 8 October 2009 (UTC)
ok i have completed the reorganization. this organization shows the relationship between each of the engines, cleans up the flow of this page, and adds the 99 or new V8 vortec engine in this page which needed to be here from the very beginning insted of just putting "car" only V8s. now all three pages that deal with the small blocks V8 (gen I thru gen IV) have the same flow and organization. Gulielmi2002 ( talk) 18:24, 9 October 2009 (UTC)
all the LS engines are SBC. yes they can be found in other brands besides Chevy just like the previous two generations. this is relativily easy and i do mean easy thing to source. after the early 80's all V8's were either a Chevrolet or Cadillac design. the name itself is in referance to small block chevrolet, example: Gen I refers to Generation I small block chevrolet; Gen II refers to Generation II small block chevrolet; and of course Gen III/IV refers to Generation III/IV small block chevrolet. should we stop calling the northstar engines Cadillac engines all together as well and just simple call them premium V8s. technically both names are valid. just like the name SBC in referance to Gen III. it is technically correct to call them GM small blocks just like it is technically correct to call them SBC. Gulielmi2002 ( talk) 16:43, 26 January 2010 (UTC)
it is both, looking at the link does say this. adding to something does mean that it is a part of it. now if the LS engines weren't SBC they line would be this : "Taking or building off (which would imply not SBC) from the grand traditions of the SBC The 5.7L Gen III LS1 introduced starting with all-aluminum construction, a thermoplastic intake manifold and drive-by-wire electronic throttle," but notice that it does say introduced new technologies to SBC. follow the link that i provided. click on the 5.7L in the break down. in the 5.7L spec page click on the Whats new and you will read the exact words that i copied and pasted here. this page predates your reference by 5 years the information predates yours by 11 years.

I've been following this discussion for the last couple of days and have read the sources provided for each side of the argument. I'm going to have to agree with the idea that the GM LS engine is a corporate engine manufactured by GM for use in all of their brands and is not Chevrolet specific in any way. If anything, GM seems to relate to the Chevrolet small-block only in marketing terms and that's probably only because the SBC has some history and identity behind its name. roguegeek ( talk· cont) 23:04, 3 February 2010 (UTC)
The sbc (not the corporate v-8 LS engines)was not a corporate engine. If it was then the Olds v-8 was as well, since they put them in several car lines from different divisions up to 1990. [7]

There is no argument when an actual cutaway engine is displayed showing that it is nothing more than a BBC with modifications and/or upgrades.

Toyota UZ engine came before Ford modular and LS engines, so why are we using Ford as an example for firing order. this follow an incorrect fanboy argument that LS engine is just a copy of a Ford design, and serves no other purpose. Ford modular 4.6L OHC only made 210hp while Northstar 4.6L OHC made 300hp, so i think Modular is a bad example of a modern engine.

I assume this is well known among people who actually do LSx swaps but do the different engines or even generations generally mate up with a given GM vehicle's existing transmission? e.g. would an LM7 bolt up to an LR4 truck? The C5+ Corvettes have transaxles so obviously the torque tube is not shared, but what about the other platforms? I'm not looking for advice, and I don't think wiki would be the place to ask for it, I just think it would be notable one way or the other in terms of the history and continuity of the "GM small-block" that has been called so since 1955. 74.96.220.27 ( talk) 09:14, 18 July 2018 (UTC)
Does LS stand for something? MBG02 ( talk) 08:33, 21 June 2019 (UTC)
I was thinking about this idly (and got into a minor argument on Facebook over it), but the LT engines shouldn't have much if any interchange with the LS engines, should they? I know the top ends are different (the valve layout in the heads is flipped: intakes on an LT are where exhausts would be on an LS and vice versa), as well as camshafts (since LT cams need an addition on the end for the HPFP, something LS engines lack), but do the rotating assemblies have any interchange at all? I had added a note about the design differences in the Gen V section but I'll admit I'm not 100% sure. Carguy1701 ( talk) 03:29, 4 March 2020 (UTC)
In my opinion the Gen VI doesn't have this place in this article. As the sources already in this section points out, the LT6 is a clean sheet design. No major parts are interchangable and the only characteristic that is tuely shared is the bore spacing.
The Gen V also had little part intechangability with the gen III end IV, but those still had an obvious filiation in the concept (pushrod 16 valve) and the general shape of the components. This is not something that we have in the Gen VI.

Since this seems to be a hot button issue, I'll quote Cadillac's own press release: "The Escalade-V’s engine shares architectural similarities with the CT5-V Blackwing’s supercharged V-8, but features a larger, 2.65L R2650 TVS supercharger that helps overcome the higher inlet and exhaust restrictions on the full-size SUV application."; Car and Driver essentially says the same thing. That sounds like it's a modified version of the LT4. However, the press release does not give an RPO code for the engine (I think the press release for the CT5-V Blackwing did, for context). I'll admit I can't see GM developing a new variant of the Gen V engine for one application, but until we've got more concrete information, I think we should hold off on adding the Escalade-V to the LT4 application table.

I've just removed the reference to the Factory Five from the LS1 section - seeing as it's not a production vehicle (it's a kit car), it's about as relevant as mentioning that there are 1993 RX-7's with LS1s. Ayocee 17:29, 30 October 2005 (UTC)

One of GM's favorite things to trumpet about the new Z06 and LS7 is that it is the first engine to be certified using SAE's J2723 test. I find it highly suspect that they would trumpet this, and yet somehow manage to 'miss' 45hp. Ayocee 02:49, 9 February 2006 (UTC)
They didn't "miss" 45hp. An unladden LS7 was SAE tested, not the Z06. The engine is rated for 505hp, and 45 hp is lost throught the drivetrain. It isn't 550hp or even 505hp by the time it gets to the wheels.-- 24.89.215.104 01:52, 21 July 2006 (UTC)
An effort should be made to adopt some unit convention, either SI (english) OR english (SI). It reduces the quality of the articles if the units are constantly mixed. For example, the engine size notation ci (cc) is proper if other measurements are cited as inches (centimeters).
That's the interesting part with American engines. The engineers design and build the block with SI, but they publicly post the engine's vital stats in english. The LT and LS blocks were both designed with SI measurement and their displacements are both advertised in metric. In this case, unit conversion should stand as "SI (english)"
With that said, it's safe to say that Detroit doesn't use cubic inches anymore. Only the old guys are calling an LS7 a "427" or an LS1 a "350".-- 24.89.215.104 23:23, 4 July 2006 (UTC)
HSV's GTS didn't use the LS6. It used the LS1, that was modified by Callaway & was designated "C4B": http://autospeed.drive.com.au/cms/A_1553/article.html Aml_0000 15:30, 6 June 2006 (UTC)
I think this should be part of the article. There was a class action suit, for LS1s, no? As I recalled there were alot of pist-off GM owners. 192.197.71.189 22:06, 13 December 2006 (UTC) CJ DUB 22:12, 29 December 2006 (UTC)
I think it's worth revisiting this topic and its merits as to inclusion in Wikipedia. My previous reply above may have been worded a bit harshly in exasperation (or whatever it was) but the fact remains that even now the only 'source' available for the problem (as well as its scope and severity) appears to be a site that would arguably fall under the category of a self-published source. I'm not trying to be combative or argumentative here, either; if there's a reputable source that actually shows evidence of piston slap being a) a problem on a significant number of engines and b) a significant issue, I'd love to see it (and cite it for Wikipedia purposes).

I have a 2004 crate LS1 that i bought from Chevrolet and installed in my 2001 Camaro, the engine has Piston Slap from day one.I just let the engine warm up before i drive and BTW I added a supercharger with 8 psi boost and still no problems from it.I drag raced for over 12 years and most of the time I set the engine up loose for piston speed and almost every time had some piston slap. it's not a problem for me. Camaro guy 11:47,June 14 2012
Anyone can say they have a LS1 with pistons slap, but i can't seem to find one even in a used dealer lot with piston slap, found a 5.0L mercury & 5.0 explorer that had piston slap with only 100k miles, and that's a smaller piston. stop making stuff up, this doesn't exist real life, in larger numbers like the 5.0L in SUV's — Preceding unsigned comment added by 24.151.159.206 ( talk) 16:48, 22 April 2014 (UTC)
There are known and easily-verified differences in the details of most LS1 variants - the cam used in the Corvette is not the same cam as in the Camaro, and the camshaft specifications changed between 1997-2000 and 2001-on. While it's likely that the actual output is closer than GM would admit, there's no reason to believe that every version of LS1 ever used was actually putting down 345hp. Ayocee 20:10, 14 December 2006 (UTC)
It's getting pretty bad with a lot of GM pages but this one is particularly bad. It looks to me that, when compared against WP:EL, none of these links pass the criteria. Thoughts? Ayocee 16:53, 28 February 2007 (UTC)

i am in the process of reorganizing this page to have the same flow as the original small block page and the LT series page. i have included the 4.8, 5.3, and the 6.0 in this page as well. Gulielmi2002 ( talk) 20:02, 8 October 2009 (UTC)
ok i have completed the reorganization. this organization shows the relationship between each of the engines, cleans up the flow of this page, and adds the 99 or new V8 vortec engine in this page which needed to be here from the very beginning insted of just putting "car" only V8s. now all three pages that deal with the small blocks V8 (gen I thru gen IV) have the same flow and organization. Gulielmi2002 ( talk) 18:24, 9 October 2009 (UTC)
all the LS engines are SBC. yes they can be found in other brands besides Chevy just like the previous two generations. this is relativily easy and i do mean easy thing to source. after the early 80's all V8's were either a Chevrolet or Cadillac design. the name itself is in referance to small block chevrolet, example: Gen I refers to Generation I small block chevrolet; Gen II refers to Generation II small block chevrolet; and of course Gen III/IV refers to Generation III/IV small block chevrolet. should we stop calling the northstar engines Cadillac engines all together as well and just simple call them premium V8s. technically both names are valid. just like the name SBC in referance to Gen III. it is technically correct to call them GM small blocks just like it is technically correct to call them SBC. Gulielmi2002 ( talk) 16:43, 26 January 2010 (UTC)
it is both, looking at the link does say this. adding to something does mean that it is a part of it. now if the LS engines weren't SBC they line would be this : "Taking or building off (which would imply not SBC) from the grand traditions of the SBC The 5.7L Gen III LS1 introduced starting with all-aluminum construction, a thermoplastic intake manifold and drive-by-wire electronic throttle," but notice that it does say introduced new technologies to SBC. follow the link that i provided. click on the 5.7L in the break down. in the 5.7L spec page click on the Whats new and you will read the exact words that i copied and pasted here. this page predates your reference by 5 years the information predates yours by 11 years.

I've been following this discussion for the last couple of days and have read the sources provided for each side of the argument. I'm going to have to agree with the idea that the GM LS engine is a corporate engine manufactured by GM for use in all of their brands and is not Chevrolet specific in any way. If anything, GM seems to relate to the Chevrolet small-block only in marketing terms and that's probably only because the SBC has some history and identity behind its name. roguegeek ( talk· cont) 23:04, 3 February 2010 (UTC)
The sbc (not the corporate v-8 LS engines)was not a corporate engine. If it was then the Olds v-8 was as well, since they put them in several car lines from different divisions up to 1990. [7]

There is no argument when an actual cutaway engine is displayed showing that it is nothing more than a BBC with modifications and/or upgrades. Firing order, size, nor does upgraded coil packs make the 8.1 not a BBC. Deck height, bore spacing, part interchangeability, and overall block architecture do, and in this case does.

Toyota UZ engine came before Ford modular and LS engines, so why are we using Ford as an example for firing order. this follow an incorrect fanboy argument that LS engine is just a copy of a Ford design, and serves no other purpose. Ford modular 4.6L OHC only made 210hp while Northstar 4.6L OHC made 300hp, so i think Modular is a bad example of a modern engine.

I assume this is well known among people who actually do LSx swaps but do the different engines or even generations generally mate up with a given GM vehicle's existing transmission? e.g. would an LM7 bolt up to an LR4 truck? The C5+ Corvettes have transaxles so obviously the torque tube is not shared, but what about the other platforms? I'm not looking for advice, and I don't think wiki would be the place to ask for it, I just think it would be notable one way or the other in terms of the history and continuity of the "GM small-block" that has been called so since 1955. 74.96.220.27 ( talk) 09:14, 18 July 2018 (UTC)
Does LS stand for something? MBG02 ( talk) 08:33, 21 June 2019 (UTC)
I was thinking about this idly (and got into a minor argument on Facebook over it), but the LT engines shouldn't have much if any interchange with the LS engines, should they? I know the top ends are different (the valve layout in the heads is flipped: intakes on an LT are where exhausts would be on an LS and vice versa), as well as camshafts (since LT cams need an addition on the end for the HPFP, something LS engines lack), but do the rotating assemblies have any interchange at all? I had added a note about the design differences in the Gen V section but I'll admit I'm not 100% sure. Carguy1701 ( talk) 03:29, 4 March 2020 (UTC)
In my opinion the Gen VI doesn't have this place in this article. As the sources already in this section points out, the LT6 is a clean sheet design. No major parts are interchangable and the only characteristic that is tuely shared is the bore spacing.
The Gen V also had little part intechangability with the gen III end IV, but those still had an obvious filiation in the concept (pushrod 16 valve) and the general shape of the components. This is not something that we have in the Gen VI.

Since this seems to be a hot button issue, I'll quote Cadillac's own press release: "The Escalade-V’s engine shares architectural similarities with the CT5-V Blackwing’s supercharged V-8, but features a larger, 2.65L R2650 TVS supercharger that helps overcome the higher inlet and exhaust restrictions on the full-size SUV application."; Car and Driver essentially says the same thing. That sounds like it's a modified version of the LT4. However, the press release does not give an RPO code for the engine (I think the press release for the CT5-V Blackwing did, for context). I'll admit I can't see GM developing a new variant of the Gen V engine for one application, but until we've got more concrete information, I think we should hold off on adding the Escalade-V to the LT4 application table.

In several places, there appear to be incorrect cubic inch displacements. For example, the 5.3L Gen V L83 is listed as being 320 ci, but the 96 mm x 92 mm creates a 325 ci displacement.
