@@AutoGuild Hah! Great question. I grew up in the midwest in the 80's/early 90's when GM's cars weren't great. My brother is a huge GM (truck) fan and I was a car guy. I was a fan of Japanese stuff - efficiency and sporty practicality. Today, as an older person I value Colin Chapman's "Simplify and add lightness" philosophy (I've owned an Elise and a ND Miata - see my channel for track day videos). My dream car is currently the T.50, but if I had under $100k I'd probably get either a Lotus Evora or a Caterham. For a daily driver I wouldn't hesitate to get a Bolt or a Volt. GM is making amazing electric vehicles and I wish more people would recognize that.
@@ChadGeidel I just watched a few videos on the T50 recently. Love it. Thats my dream car now too. And a manual GT3. We are similar, I had a 350Z and then graduated to a 986.2 Boxster S. Then I bought a pile of crap 1953 home which put my car fun on hold. But now I have a 997.2 C2S. I needed a back seat for kids! But like you I prefer small and light and mostly mid engine. My 68 Camaro I've had since high school so its a part of me now, I can never sell it. Its of course not that great to drive compared to other cars I've owned but looks cool and has amazing nostalgia! Have you driven an Elise? Its crazy raw, but I actually prefer the Cayman/Boxster...you get 98% of the performance with more creature comforts! And what do you think about the new Vette?
I'll do you one better; I'll stick with the original small block. Horsepower and efficiency be damned. They require NO sensors or computer to run. NO special tools beyond a torque wrench to assemble.
Thats the attitude your supposed to have. Same as the sbc guys that wont touch a LS because all of the scary SENSORS 🤣. The next generation with be laughing at all the LS grandpa’s that are stuck in the past. Most people are only comfortable with what they know.
We run these 6.6 ltr blocks (iron) in our natural gas gathering group. Heavy duty service, up and down very rugged mountains in Canadian Rockies. Engines work and run amazing! I've been running trucks in this environment for 24 years, and this is this best torque monster of all gas engines I've had. It doesn't have to shift as often as others, and completely reliable in our fleet. OEM trans lines blew off most every one, after -25'C. 2021 era? Just received a new one three months ago, currently -39'C and no issues. Problem resolved. Great truck, great engine!!!!!
Amen!! WHY is that sofa king difficult for people to understand?? Just the ultra-high pressure direct injection of the LT engine is enough to convince me to stick with an LS design. GDI engines have had nothing but problems, even with oil catch cans, etc installed. And the integrated Stop/Start system. Shoot me, please! Now.
Yep. I’m in Australia and I made sure I got myself the last Holden Commodore that had an LS without DoD, cam phasing and all that shit. If I gave a crap about fuel economy I wouldn’t have bought a V8!
Joke back in the day: US horsepower was measured in terms of fully grown Clydesdales and European cars measured in shetland ponies (with fantastic leather saddles).
@@peterdarr383 Of course they ran exhaust manifolds!! If you expose the exhaust valve to the atmosphere with nothing but an open, bare exhaust port, it can, and does, warp exhaust valves......
Amazing video. On a side note, the stock ECU and the LT1 respond well to a Flex Fuel sensor after an HP Tuners dyno tune session. Mine gained a total of 30whp above 93 octane.
For now I’ll stay with the LS platform The LS engines have proven they can cope with well above the factory rating and every year we see the number pushed further. The LT for the moment is not affordable ( certainly not here in Australia) and the tuning options are limited too. Certainly the LT is an excellent power plant that makes amazing torque and fuel economy and would be a great engine swap for a car that would be daily driven where the factory output is all that’s required. As the engines become affordable and development of aftermarket parts and pieces increase along with tuning options then yes I can see these engines overtaking the LS just as the LS overtook the gen1 SBC. Great content though and I’d really like to see the Camaro LT swap 💪
Absolutely!!! Yeah you should do a video of your swap into your Camaro . I’m always willing to learn about any engine you want to showcase. I love learning about the new LT engines. It’s truly crazy how much horsepower you can get now out of your engines. It use to take a lot of work to get your engine up to anything over 500hp with the technology we had but now it’s crazy how you can just go on your lap tap and change your timing your air fuel rates and see what is going on in real time it’s awesome. Thanks for the videos
Kudos to your level of detail in comparing every little difference between the two engines. Your videos are incredibly professional and a joy to watch. Thanks so much!
Please post your lt swap for 68 camaro. I found this very informative and interesting. Thanks for taking your time and money to do so. ✊✌✊ long live American Muscle ❗
Such a great video! E85 conversation kits for the LT1 seem to be working just fine. Along with other mods (heads, cam, bolt-ons) these LT1's are making 600whp NA. Yes put this engine in your Camaro.
I’ve had a ton of American v8’s but this gen 5 LT is amazing to me on how much punishment it can take and the powerband is so freaking wide. I don’t know if I’m ever getting rid of my vvt now!
It wont last its junk. That cylinder deactivation always gets gummed up nd the direct injection sprays fuel on intake valves nd causes carbon build up prematurely nd with that carbon on the valves it wont let the valves fully seat nd u will get low compression. It is advised u put injector cleaner every year
The biggest bennefit of the LT engine is that you can utalize the 10l80/90e transmission. Hp means nothing if you can’t transfer it to the wheels. Just for drivability, a 10speed is far superior to let’s say a 4l80e which I have. Just imagine an old chassis with 10speed and paddle shift. Fast up and down shifts.
Those 10 speeds are ass 17-18’s are camaro SS fastest stock production cars end 8 speeds. The 10 speed is just simply too much gear for an LT in the digs.
I know two guy with a 2020 and a 2022 5.3 V8 silverado trucks with catastrophic engine failure both under 20k miles. My 05 silverado has a small block its been a great motor I change my oil every 3500 miles it only has 71k on it so.
The problem with the 90s version of the LT1 was that the distributer "optispark ignition" was located under the water pump. The water pump failed a known problem, then it would foul the ignition system due to moisture. I have personally seen this in my 1993 firebird formula.
Great presentation. I wondering about the details of the integrated PCV system now, especially considering how direct injected systems are typically prone to dirty intake valves. I love the new cast headers and heat shields, and the gussetted water jacket.
Bro for rookies like me who want to learn about these engines, you've done an amazing job making this video and teaching us about these engines, AMAZING JOB BRO..GOD BLESS AND THANK YOU
Totally agree Mark, that system is terrible on any vehicle. It can be turned off but has to done every time you turn the key. Pain in the ass! But the aftermarket has come to the rescue. I say a plug and play controller that turns it off for good. Don’t remember the name of hand. But a google search will find it.
@@Elmiki007 Whether you like start-stop or not, we get much better heavy duty starters because of it. Ask around cars that have start-stop very rarely if ever have failed starters compared to cars without start-stop. The starters are lasting the life of the car.
I may have gotten in over my head, but I just purchased a 2014 LT1/L83 from a Silverado. It came with the 6L80E trans and they gave me every piece of wiring associated with the engine compartment including the fuse block and pedal. I have a box of wiring that's 2x2x3 feet full of wiring harnesses. If you're doing an LT swap, I would be very interested. My plan is to put this in my 37 Chev Pickup.
I gotta tell ya, this is BY FAR the best explanation video I've seen. GREAT job! I've been spinning wrenches on cars as far back as I can remember. I actually rebuilt my first sbc when I was 14. My older brothers were blown away that it ran strong and smooth when I was done with it. They kept snickering under their breath at me as they watched me put it together. I'm still not sure who was happier when it fired up for the first time, me or them! Ha! I've been retired for a while now but I never stopped building cars. I still have several SBC's on engine stands waiting for homes including 4, 400's. (406 ci now) Also a BB 427 with a all steel rotating assembly. It's almost 2021 and the LS has been out since 1997 but I've YET to do a swap with one into an older vehicle. Now the LT is going on 7 years old!!! I guess I need to give some serious thought to stepping into the 21st century. 😂 Loved the video and I think it would be awesome to see a LT swap into your Camaro.
Until injectors become available, the LT platform is pointless, especially in C8 trim, as the ECUs are still locked. Put an LS into your car and thank yourself for it in the long run.
No doubt Ls is the most efficient and economical swap. I personally am loya too the Lt1 but you cant even compare to the Lt5 6.2 come on, Hands down and im speaking stock. Because if not im stroking a small block
There are plenty of injectors available for the LT1. The LT4 injectors are good for a lot more hp than what the LT4 puts out. Upgrade the fuel pumps and switch to flex fuel and it can make good power. Also the LT1 can be tuned by tons of people.
Stock to stock the LT is better. But when you start doing mods the ls way more user friendly. Where are all the turboed LTs? They've been out for 10 years
I’d love to see that series, I’m personally thinking of buying my dads 68 in the next few years and I was gonna put an LS in there but with how engines are nowadays an LT would be real nice.
@@AutoGuild do more information on the ls. I've got a 67 Camaro I'm thinking about replacing my 572 - 700 hp 710 torque to a little LS for gas mileage. I'll have to spray it with nitrous or screw blower to keep up with or beat the 572 engine. The ls though is a lot lighter engine.
Depends on what you mean by better. Yes the LTs make more power. Factory blocks are stronger. But that additional power comes at a cost. Complicated systems that are well known for premature failure. The early LS engines are simple and last a very long time with zero issues. AFM has ruined these engines. LSs and LTs. I personally don’t understand how GM is not in a major lawsuit with a broad spectrum of AFM issues for nearly two decades. Excessive oil consumption, premature cam and lifter failure being the major issues.
My LS6 2004 Z06 Corvette Commemorative engine is the best engine I've ever owned. My 96 Vette was fine, but this LS6 engine with over 100,000 miles still runs like new and doesn't leak a drop. Gets good gas mileage on the highway. Origional clutch also. Previously I was a MOPAR buyer. Mostly 440s. Great engine.
I’m a Ford guy but recently came across a G body Buick Regal I couldn’t pass up. Only problem is the tired old 307 Olds motor is done and so is the transmission. No surprise there. So a buddy of mine who’s a GM guy got me to thinking about an LS swap. I don’t want anything too radical. It has to be drivable and reliable. Only problem is I don’t trust GM ‘s for a lot of reasons. So I really need to do my research here and come to a change of heart before I approach this car. Your videos are part of that research.
Love my LS engine. The one you didn't mention. The 427 7.0 liter LS7! I make 544whp with mind cam with tons of low end torque. Fast enough to go from 0 to locked up in seconds, lol!
One correction: The LT1 engine is flex fuel capable; however it does not come ready from the factory. If you install an alcohol sensor to the fuel line and ecu, a tuner can turn on the flex fuel function.
No it is not flex fuel. All engines can handle a minimim amount upto 10 or 12% but thats it. If you dont upgrade the fuel system at a minimum, your asking for trouble. Same for Ford V8. The F150 5.0 is based on the old Crown Vic V8, thus 100% flexfuel compatable. There are differences betwern it and the mustangs V8 which is why such huge difference in power.b
@@MasterCarguy44-pk2dq you’re wrong actually, any car equipped with an LS/LT already has the fuel system capable of handling the additional ethanol content. Op is right, all you have to is install a flex fuel sensor to vary the timing based on ethanol content in the gas, part/kit is about $200-$300. Once you do that you activate it via hptuners
@LangeLS4 it's the lack of of extra fuel and dod. Di is a bar thing unless extra fuel is introduced. Ford mustang in 2018 had the world's first duel fuel system. It works great however no dod. Now for 24 Ford added did on mustangV8 and dance its v8 isn't technically the same as F150 l, mustang V8 is not E85, only "Upto" E15.
The V8 engines in Camaro, Corvette, trucks etc are not E85 compatible. You must buy a lit just like on all other manufacturers V8 performance vehicles. GM V6 is also not flex. There is a program to alter some systems however your performance V8 is no-go E85. It is safe to run upto E20 though. The down side is worse mpgs and a slight 10-14 hp increase. To me not worth the lower cost of sugar water contamination in my cylinders, on plugs, valves, etc.
The LT is a really danged impressive design!!! EXCELLENT summary. I did not speed up this video. How is the LT for 500 hrs of full load operation at 5000-6500 RPM? What breaks, anything? 1955 Mercedes Gullwing had direct injection, finally mainstream. That is a long road for technology development. I wish my airplane engine had this block stiffness.
Using an LT in your 68 will be a good choice, I'm leaning that way for my 69 Camaro. From what I have seen in a couple builds, you will need to modify the transmission tunnel for the correct drivetrain angle and perhaps the lower firewall for fuel pump clearance depending on how far forward the engine sit's in the bay. Different aftermarket frame choices might make a difference on the firewall clearance and oil pan choice.
Thanks for the comment. Yeah Im just getting stated researching it. I feel like LT will be a pain but there is not much info out there on it so Im going to try and do it and cover the entire process with my videos. Stay tuned. : )
But the most amazing thing about direct injection engines is that with out fuel being sprayed onto the backs of the intake valves, oil vapours sent into the intake system from the positive crank case ventilation system can burn onto the backs of the valves causing valve coking, a problem that was solved over a decade ago by port fuel injection.
Sad he didn’t bring this up. I know several people that have seen this issue with direct injection engines. Had to get expensive walnut blasting to clean the valves.
This was very interesting, thanks. I understand the government mandates pushed the engine development (from Gen 3 to Gen 4 with AFM) in a direction of lowered reliability. With the latest LT, is this still motivated by mileage? Some argue for the simplicity of the old 350. The reliability jump with the Gen 3 was significant however. My LM7 is still going strong after 275k miles. I only changed the knock sensors, intake manifold gaskets, and a few water pumps. All very easy to do by myself with 10mm and 13mm tools. These Gen 3 engines with their controls seem to be able to take a lot of abuse and provide service for a very long time. I accept the mpg hit for an engine that may outlast the body. Interested in your perspective on this.
I remember driving performance cars back then in the 70s when muscle cars were still king. Power wise regarding low end grunt not that much different than today relatively speaking. Sure todays cars are quicker but the old performance cars were no slouch. The drawback to actual 1/4 mile times then were vintage 3 speed automatic and 4 speed manual transmissions compared to modern 6 speed close ratio manual transmission an 8 and 10 speed automatic transmission that allow very little rpm drop between gears. Also todays engines wind out to a higher rpm. Stickier tires also help with better acceleration. RPM on the Vintage vehicle was 5500 to maybe close to 6k. The modern LT1 is redlined around 6500, some say its good and safe beyond that and some tunes actually raise the redline. The Vintage iron had nowhere near the top end of our cars today.
The LT seems pretty amazing in capability's, but I just wonder if it will have the reliability of even the old small block. Direct injection leads to grungy intake valves and lose of power as well as expense at the repair shops. VVT is a power booster, but also prone to fail due to complexity. Thinner piston rings break easier. Aluminum block? Does it at least have iron liners? And big horsepower numbers alone are not indicative of what makes for a " good " engine. They are only part of the math formula for an engine's power output in this country. Kilowatt output, which Europe uses to express engine power is more relevant today.
I thought the vid was great. I am a retired mechanic and college teacher and have worked on every size of diesel that one can imagine. The 6.6 LT iron block must come from the DuraMax diesel. Every phase of that engine design, gusseted water jackets, Direct Injection, dished pistons and oil squirt piston cooling all comes directly from diesel technology. Keep up the great vids. I would like to see an LT 6.6L gas, swapped into a IH Scout with everything else coming from a 90's something Toyota 4Runner. I have a 1966 Scout and a 1997 4Runner.
Direct injection has me pondering how the intake valves and ports will be kept cleaned of the PCV gunk. Perhaps a secondary injector set in the intake runners?
Yes, that is the key. Subaru’s FA20 engine has both direct and port injectors (8 injectors in a 4cyl). They say it’s for maximum efficiency at any RPM but it also has the side effect of cleaning the valves. Ford’s revamped Coyote 5.0 also has direct and port injectors, 16 total. For an engine with only direct injection, the poor man’s solution is running an oil catch can on the PCV line to catch and filter out any oil vapor before it recirculates.
That's how it would normally be done like with Toyota's D-4S system. However here he didn't mention anything of the sort so that means about every 30,000 miles you have to get your intake valves cleaned or else you have emissions issues as well as power loss
Like the fellow commenting below me, I grew up on ford and was a adamant ford kind of guy. Now I am old by most standards... mine included but for sure, listening to you explain the differences an showing pictures of what your referring to is right up my ally. I am for sure a picture guy .... kinda like the old Thompson repair manuals of the thirties and early forties. I'm 73 and wrenched most all those years. If I still loved only fords, I would go to that iron block LS engine. Thats what all of us open fender hot rod guys did was swap what you could get into what you had. I have to say that your the man I can understand completely. We have a LS engine on our jet boat and its okay, I can see that sometime in the future a LT engine will live there!!
A repair shop owner took rusted 69 Camaro did custom build. A wrecked Z06 the suspension and engine transplant. Took 3 years and thousands of dollars it runs beyond belief and handles extremely well. To each their own I had Nova SS pulled 350 made 406 with lunati racing cam aluminum intake big Carter carb. It ran very well added larger ASB front and rear, so much so you moved against the door car stayed level with F41 springs and poly bushings and gas shocks rode like grain truck at low speeds highway rode far better. I say research your changes.
I’m absolutely in LOVE with my LS3 Camaro SS. I’d love to put an LS3 in my next project. I’ve never tried any LT’s but I’m sure I’d love them. Like others have said here, I’m poor and my costs need to be low as possible
I would LOVE to see details on your LT swap in your 68 Camaro! I'm considering an LT swap in my 67, and am struggling with picking out either a drop out / or a new build when having to consider so many things (ECU/Wiring harness/Transmission that will fit/Transmission which requires tunnel surgery/front accessory clearance on subframe, etc..
Camming my LS3 Vette resulted in a 65 rwhp gain on the dyno, no other mods on stock engine. There is so much potential in the LS. Would even venture to say the factory stock 430hp LS is a detuned race engine.
I have an LY-6 in my 2008 Chevy 2500 Express van. I read that the LY-6 is actually an iron-block LS-3 with aluminum heads. This engine is known for its strength in trucks and vans, and can be boosted to make nearly 1,000 hp, without harm to the engine. Since it’s not an aluminum block, the cost is much less than an LS-3 and it is sought out for racing.
I'm sort of new to this and appreciate videos like this because there's a lot to learn. The LS engines still appeal to me more though for two reasons: Big block and 32 valves (meaning the LS7 is the only option). It would be nice if the LT lineup could offer those 2 things especially considering their direct injection technology and continuous variable valve timing. Otherwise, I'd probably be more inclined to go with an LS motor as they are arguably more reliable and much simpler to work on. Great video!
Amazing engine right up until “auto start/stop.” The absolute stupidest thing ever invented. Thanks for the knowledge, good stuff! My newest sandcar will be getting a LT4 and I’m very excited.
@@AutoGuild Quick question, depending how you look at it. I have a project build 1998 Chevy S-10, 2.2, 5 spd that I want to do an LS swap but after watching this video what engine would be the most viable option of swapping? I’ve been doing research and watching videos like yours and I see most prefer the truck 5.3 because of their availability and iron block but I still will need a manual transmission, ECU, fuel management etc. I even seen the video where you have to swap out the intake and front due to the larger truck intake. Thank you for whatever you may be able to help me with!
Direct injection has a flaw, in that the time available for evaporation of the fuel is less than with port injection, which also adds mechanical agitation to the fuel:air mix to homogenize the mixture. The advantage is that the fuel:air ratio is much richer in the immediate area of the spark plug, leading to a faster-igniting charge and a wider initial flame front. The optimum would be far upstream (pre-compressor in supercharge engines) lean mix, augmented by a compensatory direct injection in small quantity to balance the fuel:air ratio and ignite the lean mixture with the flame front, instead of the spark, reducing the need for spark advance.
I'm a computer engineer. "Lines of code" is a pretty useless and misleading number these days. I'd be more worried about the integrated PCV and variable displacement oil pump, personally. Code doesn't clog and deteriorate over time.
Here's a news flash for you. I took the 350 c I engine out of a wrecked 96 Impala SS and took it to 383 c. I. Using a 6 inch rod and a stroker crank. AFR heads comp roller hydraulic cam. Result was 450 hp and 460 ft lbs of torque. Plenty of vacuum works with stock converter.
My 94 Impala SS had the LT in it, the best car I've ever had, drove it for 17 years and spent not one cent on the motor, and it pulled like a bull till the day I sold the car. The guy that bought the car used the drive train to make a circle car dirt track racer.

I say go for the LT swap on your 68! It's something that not to many people are doing right now. Plus it would be a great build to see on TH-cam!
Absolutely!!! Yeah you should do a video of your swap into your Camaro . I’m always willing to learn about any engine you want to showcase. I love learning about the new LT engines. It’s truly crazy how much horsepower you can get now out of your engines. It use to take a lot of work to get your engine up to anything over 500hp with the technology we had but now it’s crazy how you can just go on your lap tap and change your timing your air fuel rates and see what is going on in real time it’s awesome. Thanks for the videos
10:26 oh... now I finally understand why blow-by is more prevalent with direct injection.
Kudos to your level of detail in comparing every little difference between the two engines. Your videos are incredibly professional and a joy to watch. Thanks so much!
I do love the fact that the newest LT1(2014-Now) share the same serpentine belt routing as the Gen II LT1(1992-1997).
Please post your lt swap for 68 camaro. I found this very informative and interesting. Thanks for taking your time and money to do so. ✊✌✊ long live American Muscle ❗
I haven't seen any LT platform cars built to 8.2 liters yet. My "LS7" is a full 502ci.
Such a great video! E85 conversation kits for the LT1 seem to be working just fine. Along with other mods (heads, cam, bolt-ons) these LT1's are making 600whp NA. Yes put this engine in your Camaro.
I own the LT4 in my C7 Z06 I just love the Lt4 engine.
Just wait till it breaks
The LT1 is the best kept secret. You'll hit 100 mph and not even feel like it. It's powerful

@@MasterCarguy44-pk2dq and you believe in the Easter bunny, tooth fairy and Santa too right?
I’ve had a ton of American v8’s but this gen 5 LT is amazing to me on how much punishment it can take and the powerband is so freaking wide. I don’t know if I’m ever getting rid of my vvt now!
It wont last its junk. That cylinder deactivation always gets gummed up nd the direct injection sprays fuel on intake valves nd causes carbon build up prematurely nd with that carbon on the valves it wont let the valves fully seat nd u will get low compression. It is advised u put injector cleaner every year
@@jackdaniels2657direct injection does NOT spray fuel on the valves, direct injection sprays directly into the cylinder
The biggest bennefit of the LT engine is that you can utalize the 10l80/90e transmission. Hp means nothing if you can’t transfer it to the wheels. Just for drivability, a 10speed is far superior to let’s say a 4l80e which I have. Just imagine an old chassis with 10speed and paddle shift. Fast up and down shifts.
Those 10 speeds are ass 17-18’s are camaro SS fastest stock production cars end 8 speeds. The 10 speed is just simply too much gear for an LT in the digs.
I know two guy with a 2020 and a 2022 5.3 V8 silverado trucks with catastrophic engine failure both under 20k miles. My 05 silverado has a small block its been a great motor I change my oil every 3500 miles it only has 71k on it so.
Def should not happen at that low of miles. GM needs to address this issue for sure.
I am currently working on a LT1 swap into a 67 Camaro so I would love to see it in your 68!
ok so where is it at?
The problem with the 90s version of the LT1 was that the distributer "optispark ignition" was located under the water pump. The water pump failed a known problem, then it would foul the ignition system due to moisture. I have personally seen this in my 1993 firebird formula.
My ‘96 LT4 Vette is apart right now for just that…. Water pump and opti spark
Great presentation.
I wondering about the details of the integrated PCV system now, especially considering how direct injected systems are typically prone to dirty intake valves.
I love the new cast headers and heat shields, and the gussetted water jacket.
You talked about all the upsides of the engine but none of the downsides, like the problems that come with direct fuel injection, like carbon buildup
Bro for rookies like me who want to learn about these engines, you've done an amazing job making this video and teaching us about these engines, AMAZING JOB BRO..GOD BLESS AND THANK YOU
An "integrated Stop-Start system" for improved mileage? I hope it can be turned off. I don't want that crap on any vehicle I own.
Gm thinks you can save 100bucks a year on gas from stop-start but then your starter motor cost you 300-800 to replace
Totally agree Mark, that system is terrible on any vehicle. It can be turned off but has to done every time you turn the key. Pain in the ass! But the aftermarket has come to the rescue. I say a plug and play controller that turns it off for good. Don’t remember the name of hand. But a google search will find it.
I never use mine. First thing I do immediately after fire up is push off the start/stop. I have learned my all family to do that too
@@Elmiki007and battery.
Only if you have long stops on idle you save something.
@@Elmiki007 Whether you like start-stop or not, we get much better heavy duty starters because of it. Ask around cars that have start-stop very rarely if ever have failed starters compared to cars without start-stop. The starters are lasting the life of the car.
I never did a LS engine swap... Now the LT5 came out and Im impressed so I bought me 1 for my Chevelle.
650 hp stock out of 5.5L is fuming crazy
Did you ever finished your project??
Do a LT swap I'd rather see that and enjoy watching it than be educated Good video though very educational
I may have gotten in over my head, but I just purchased a 2014 LT1/L83 from a Silverado. It came with the 6L80E trans and they gave me every piece of wiring associated with the engine compartment including the fuse block and pedal. I have a box of wiring that's 2x2x3 feet full of wiring harnesses. If you're doing an LT swap, I would be very interested. My plan is to put this in my 37 Chev Pickup.
Oh man good luck, do you have a post on a forum where I can see some pics or get some info?
@@AutoGuild I do not.
I gotta tell ya, this is BY FAR the best explanation video I've seen. GREAT job! I've been spinning wrenches on cars as far back as I can remember. I actually rebuilt my first sbc when I was 14. My older brothers were blown away that it ran strong and smooth when I was done with it. They kept snickering under their breath at me as they watched me put it together. I'm still not sure who was happier when it fired up for the first time, me or them! Ha! I've been retired for a while now but I never stopped building cars. I still have several SBC's on engine stands waiting for homes including 4, 400's. (406 ci now) Also a BB 427 with a all steel rotating assembly. It's almost 2021 and the LS has been out since 1997 but I've YET to do a swap with one into an older vehicle. Now the LT is going on 7 years old!!! I guess I need to give some serious thought to stepping into the 21st century. 😂 Loved the video and I think it would be awesome to see a LT swap into your Camaro.
I rebuilt my first small block at 15 so you have me beat!
Until injectors become available, the LT platform is pointless, especially in C8 trim, as the ECUs are still locked. Put an LS into your car and thank yourself for it in the long run.
No doubt Ls is the most efficient and economical swap. I personally am loya too the Lt1 but you cant even compare to the Lt5 6.2 come on, Hands down and im speaking stock.
Because if not im stroking a small block
Higher flow Injectors are available, but the stock LT4 fuel system has proven itself to over 800hp
There are plenty of injectors available for the LT1. The LT4 injectors are good for a lot more hp than what the LT4 puts out. Upgrade the fuel pumps and switch to flex fuel and it can make good power. Also the LT1 can be tuned by tons of people.
You’re crushing it. Keep it up.
Thanks, much appreciated! Let me know what other types of videos you'd like to see.
@The Shapeshifters Misale I have a video on that already, search youtube for "history of the LS engine" : )
The e85 conversion kits seem to work with LT1s.
Stock to stock the LT is better. But when you start doing mods the ls way more user friendly. Where are all the turboed LTs? They've been out for 10 years
I’d love to see that series, I’m personally thinking of buying my dads 68 in the next few years and I was gonna put an LS in there but with how engines are nowadays an LT would be real nice.
I prefer the LS3 in my 2013 Grand Sport to the LT1 in my 2017 GS. The LS has a smoother feel. Also, no cylinder deactivation tech in the LS.
But the entire reason for the LS swaps popularity is price and availability. Show me where I can get a perfectly running LT motor for $250 lol

@@AutoGuild do more information on the ls. I've got a 67 Camaro I'm thinking about replacing my 572 - 700 hp 710 torque to a little LS for gas mileage. I'll have to spray it with nitrous or screw blower to keep up with or beat the 572 engine. The ls though is a lot lighter engine.
Depends on what you mean by better. Yes the LTs make more power. Factory blocks are stronger. But that additional power comes at a cost. Complicated systems that are well known for premature failure. The
early LS engines are simple and last a very long time with zero issues. AFM has ruined these engines. LSs and LTs. I personally don’t understand how GM is not in a major lawsuit with a broad spectrum of AFM issues for nearly two decades. Excessive oil consumption, premature cam and lifter failure being the major issues.
My LS6 2004 Z06 Corvette Commemorative engine is the best engine I've ever owned. My 96 Vette was fine, but this LS6 engine with over 100,000 miles still runs like new and doesn't leak a drop. Gets good gas mileage on the highway. Origional clutch also. Previously I was a MOPAR buyer. Mostly 440s. Great engine.
The engine power upgrade wasn't the main thing. Its the new mid engine layout. It makes the car handle and drive way more fun.
Yes, do an LT swap on your 68 Camaro. Also you should consider making a video on the Vortec 4200
I’m a Ford guy but recently came across a G body Buick Regal I couldn’t pass up. Only problem is the tired old 307 Olds motor is done and so is the transmission. No surprise there. So a buddy of mine who’s a GM guy got me to thinking about an LS swap. I don’t want anything too radical. It has to be drivable and reliable. Only problem is I don’t trust GM ‘s for a lot of reasons. So I really need to do my research here and come to a change of heart before I approach this car. Your videos are part of that research.
Love my LS engine. The one you didn't mention. The 427 7.0 liter LS7! I make 544whp with mind cam with tons of low end torque. Fast enough to go from 0 to locked up in seconds, lol!

Never had an LS still stuck in the past in my 70' Firebird and 89' Camaro 🤣
How do they deal with the pepetual problem of intake valve stem carbon with GDI despite a more efficient EGR system?
Yep, that is a problem. My daily driver has DI too. Ford has a good solution in the Coyote but that adds cost and complexity.
I loved the LS Engines until I cheated and fell in LOVE with Gen V LT1....
One correction: The LT1 engine is flex fuel capable; however it does not come ready from the factory. If you install an alcohol sensor to the fuel line and ecu, a tuner can turn on the flex fuel function.
No it is not flex fuel. All engines can handle a minimim amount upto 10 or 12% but thats it. If you dont upgrade the fuel system at a minimum, your asking for trouble. Same for Ford V8. The F150 5.0 is based on the old Crown Vic V8, thus 100% flexfuel compatable. There are differences betwern it and the mustangs V8 which is why such huge difference in power.b
@@MasterCarguy44-pk2dq you’re wrong actually, any car equipped with an LS/LT already has the fuel system capable of handling the additional ethanol content. Op is right, all you have to is install a flex fuel sensor to vary the timing based on ethanol content in the gas, part/kit is about $200-$300. Once you do that you activate it via hptuners
@@MasterCarguy44-pk2dqmy 06 impala with a 5.3 is ran on E85, has been for almost a year now with no issues. Didn’t change anything in the fuel system
@LangeLS4 it's the lack of of extra fuel and dod. Di is a bar thing unless extra fuel is introduced. Ford mustang in 2018 had the world's first duel fuel system. It works great however no dod. Now for 24 Ford added did on mustangV8 and dance its v8 isn't technically the same as F150 l, mustang V8 is not E85, only "Upto" E15.
The V8 engines in Camaro, Corvette, trucks etc are not E85 compatible. You must buy a lit just like on all other manufacturers V8 performance vehicles. GM V6 is also not flex. There is a program to alter some systems however your performance V8 is no-go E85. It is safe to run upto E20 though. The down side is worse mpgs and a slight 10-14 hp increase. To me not worth the lower cost of sugar water contamination in my cylinders, on plugs, valves, etc.
Thanks. Now I know a little more about my 1LE.
I took a lot of screenshots on this one! This is why I'm an annoying know it all.
...Akshully...
The LT is a really danged impressive design!!! EXCELLENT summary. I did not speed up this video. How is the LT for 500 hrs of full load operation at 5000-6500 RPM? What breaks, anything? 1955 Mercedes Gullwing had direct injection, finally mainstream. That is a long road for technology development. I wish my airplane engine had this block stiffness.
Using an LT in your 68 will be a good choice, I'm leaning that way for my 69 Camaro. From what I have seen in a couple builds, you will need to modify the transmission tunnel for the correct drivetrain angle and perhaps the lower firewall for fuel pump clearance depending on how far forward the engine sit's in the bay. Different aftermarket frame choices might make a difference on the firewall clearance and oil pan choice.
Thanks for the comment. Yeah Im just getting stated researching it. I feel like LT will be a pain but there is not much info out there on it so Im going to try and do it and cover the entire process with my videos. Stay tuned. : )
But the most amazing thing about direct injection engines is that with out fuel being sprayed onto the backs of the intake valves, oil vapours sent into the intake system from the positive crank case ventilation system can burn onto the backs of the valves causing valve coking, a problem that was solved over a decade ago by port fuel injection.
That's exactly right that's why I would not buy a new LT engine
Sad he didn’t bring this up. I know several people that have seen this issue with direct injection engines. Had to get expensive walnut blasting to clean the valves.
LT have more power, but we still Rock with LS engine 💪🏽😎
This was very interesting, thanks. I understand the government mandates pushed the engine development (from Gen 3 to Gen 4 with AFM) in a direction of lowered reliability. With the latest LT, is this still motivated by mileage? Some argue for the simplicity of the old 350. The reliability jump with the Gen 3 was significant however. My LM7 is still going strong after 275k miles. I only changed the knock sensors, intake manifold gaskets, and a few water pumps. All very easy to do by myself with 10mm and 13mm tools. These Gen 3 engines with their controls seem to be able to take a lot of abuse and provide service for a very long time. I accept the mpg hit for an engine that may outlast the body. Interested in your perspective on this.
I remember driving performance cars back then in the 70s when muscle cars were still king. Power wise regarding low end grunt not that much different than today relatively speaking. Sure todays cars are quicker but the old performance cars were no slouch. The drawback to actual 1/4 mile times then were vintage 3 speed automatic and 4 speed manual transmissions compared to modern 6 speed close ratio manual transmission an 8 and 10 speed automatic transmission that allow very little rpm drop between gears. Also todays engines wind out to a higher rpm. Stickier tires also help with better acceleration. RPM on the Vintage vehicle was 5500 to maybe close to 6k. The modern LT1 is redlined around 6500, some say its good and safe beyond that and some tunes actually raise the redline. The Vintage iron had nowhere near the top end of our cars today.
For sure, tires made a huge difference, many people dont realize that! Great comment. : )
This was great detail and lines up with a lot of our content on the history of Corvette propulsion. Camaro engine swap? I vote small block LS7!
LSA checking in 🤝🏿
The LT seems pretty amazing in capability's, but I just wonder if it will have the reliability of even the old small block. Direct injection leads to grungy intake valves and lose of power as well as expense at the repair shops. VVT is a power booster, but also prone to fail due to complexity. Thinner piston rings break easier. Aluminum block? Does it at least have iron liners? And big horsepower numbers alone are not indicative of what makes for a " good " engine. They are only part of the math formula for an engine's power output in this country. Kilowatt output, which Europe uses to express engine power is more relevant today.
don't all aluminum blocks use cylinder liners?
Gotta love those oil spray jets.
U can put that on lsx
Talk about breaking down the Chevrolet small block family of engines. Thank you for making this video. I will be watching more of these.
I thought the vid was great. I am a retired mechanic and college teacher and have worked on every size of diesel that one can imagine. The 6.6 LT iron block must come from the DuraMax diesel. Every phase of that engine design, gusseted water jackets, Direct Injection, dished pistons and oil squirt piston cooling all comes directly from diesel technology. Keep up the great vids. I would like to see an LT 6.6L gas, swapped into a IH Scout with everything else coming from a 90's something Toyota 4Runner. I have a 1966 Scout and a 1997 4Runner.
Love the old Scouts, just hard to find parts for them I think! Can u share a link with some pics?
Direct injection has me pondering how the intake valves and ports will be kept cleaned of the PCV gunk. Perhaps a secondary injector set in the intake runners?
Fog it with steam occasionally.
Yes, that is the key. Subaru’s FA20 engine has both direct and port injectors (8 injectors in a 4cyl). They say it’s for maximum efficiency at any RPM but it also has the side effect of cleaning the valves.
Ford’s revamped Coyote 5.0 also has direct and port injectors, 16 total.
For an engine with only direct injection, the poor man’s solution is running an oil catch can on the PCV line to catch and filter out any oil vapor before it recirculates.
Yes, Ford did the Direct, and Port injection in their 2017+ F150s. 2.7TT, 5.0V8, 3.5TT all have duel injection, and it works.
That's how it would normally be done like with Toyota's D-4S system. However here he didn't mention anything of the sort so that means about every 30,000 miles you have to get your intake valves cleaned or else you have emissions issues as well as power loss
I thought he said the intake ports and valves only handle clean,filtered air.Where's the gunk coming from?

definitely would love to see that engine swap :)
Me too
Look on here, I saw a c10 with a LT4 swap
LS is better they are everywhere plus parts are easy accessible.
Comparing an older 5.7L to a newer 6.2L engine, no sh*t the 6.2 makes more power.
Camming my LS3 Vette resulted in a 65 rwhp gain on the dyno, no other mods on stock engine. There is so much potential in the LS. Would even venture to say the factory stock 430hp LS is a detuned race engine.
I have an LY-6 in my 2008 Chevy 2500 Express van. I read that the LY-6 is actually an iron-block LS-3 with aluminum heads. This engine is known for its strength in trucks and vans, and can be boosted to make nearly 1,000 hp, without harm to the engine. Since it’s not an aluminum block, the cost is much less than an LS-3 and it is sought out for racing.
I'm sort of new to this and appreciate videos like this because there's a lot to learn. The LS engines still appeal to me more though for two reasons: Big block and 32 valves (meaning the LS7 is the only option). It would be nice if the LT lineup could offer those 2 things especially considering their direct injection technology and continuous variable valve timing. Otherwise, I'd probably be more inclined to go with an LS motor as they are arguably more reliable and much simpler to work on. Great video!
Seems like a perfect engine as long as you disable afm and on demand start
Can’t do that yet

@@AutoGuild Quick question, depending how you look at it. I have a project build 1998 Chevy S-10, 2.2, 5 spd that I want to do an LS swap but after watching this video what engine would be the most viable option of swapping? I’ve been doing research and watching videos like yours and I see most prefer the truck 5.3 because of their availability and iron block but I still will need a manual transmission, ECU, fuel management etc. I even seen the video where you have to swap out the intake and front due to the larger truck intake. Thank you for whatever you may be able to help me with!
Direct injection has a flaw, in that the time available for evaporation of the fuel is less than with port injection, which also adds mechanical agitation to the fuel:air mix to homogenize the mixture. The advantage is that the fuel:air ratio is much richer in the immediate area of the spark plug, leading to a faster-igniting charge and a wider initial flame front. The optimum would be far upstream (pre-compressor in supercharge engines) lean mix, augmented by a compensatory direct injection in small quantity to balance the fuel:air ratio and ignite the lean mixture with the flame front, instead of the spark, reducing the need for spark advance.
2.9 million lines of code to use an LT? No thanks, I'll use the LS.
I'm a computer engineer. "Lines of code" is a pretty useless and misleading number these days. I'd be more worried about the integrated PCV and variable displacement oil pump, personally. Code doesn't clog and deteriorate over time.
Newer tech is better than older?! Wow what a revelation!

AFR heads comp roller hydraulic cam. Result was 450 hp and 460 ft lbs of torque. Plenty of vacuum works with stock converter.
My 94 Impala SS had the LT in it, the best car I've ever had, drove it for 17 years and spent not one cent on the motor, and it pulled like a bull till the day I sold the car. The guy that bought the car used the drive train to make a circle car dirt track racer.
