I didn’t expect to watch this video and see myself building my own engine! Very well done video and very informative. One HUGE thing to mention on LS/LT swaps is the availability and difficulty of tuning the LT engines. The learning curve is much higher and everything is “torque” based in HP tuners for the LT engines. My LT5 has been an absolute pain to tune and while tons of shops say they can tune them, really only Cordes Performance and Advanced Modern Performance seem to have the guys that have really mastered them.

What's so great about the Ls is you can pretty much grab any variety from the junk yard for 500 bucks, slap some cheap turbos on it, and go faster than anything in your general area. It's great.

I like how you said the internet says you need at least 1000hp. My 505 LS7 is plenty for getting into trouble. Even the C5 Z06 feels very fast. YouTube makes everyone who hasn't driven a fast car yet think these are slow. Hell, a fiesta st is a ton of fun with 197hp.

I've had many LS 6.0 in all of my GM pickups for over 20 years with no problems. My current survivor truck is a 1999 Chevy Silverado 2500 LD 4 X 4 with the LS 6.0 3 door EXT Cab with 6.5' bed. This truck has pulled everything from a 13, 000LB Toy Hauler Travel Trailer with 2 full dress Harleys in it to boats and car carriers. It now has 350, 000 on the original engine, runs like new does not burn oil. Push rod engines are simple and simple is good.

I remember in the late 90s when the traditional small blocks were the older cheaper tech and LS was exotic and expensive.
You could still get a cheap pre smog small block with good for the time heads that would make power cheap.
LS was only in Vettes and F body’s and they were expensive.
Cool to see the progression.

Don’t stop making these kind of videos . You’re going to get huge doing these type of videos . You have a lot of good info and it’s very well put together.

The LS3's 55mm intake valve was actually sized for a 6.8L and higher RPM, and they used some tricks to make it work on the 6.2. That's why the LT went to a smaller 54mm valve...which is still too big. That "big" LT port is the secret to the low end torque; the VVT is just icing on the cake.

You left out the OG "variant" 5.7 !! LS1

[fortheloveofnoise]

Good thing about the LT1 that came out before the LS was it was the last "oldschool" sounding engine, sounds great!

[MalcolmV]

I’d love to see a video just dedicated to all the popular LS variants and their differences and what vehicles they came from etc. that’s always very interesting info.

[stevetrkulja]

In conclusion, the one that has been around longer is easier to get and is cheaper to work with...obviously lol. If the new gen LT was out first it'd be flipped. It's all about having time to adapt and availability of kits/parts which grows with time. Both are great! Solid comparison video too.

[fideltrujillo]

Best part of the LS is the packaging and how light they are . They fit in everything and make great power. Win win !

[dazaspc]

You left out the LS 5.7 the original
The great beauty of the LS is the crank mounted oil pump. This give many options oil pan wise along with the small top end giving plenty of room for accessories along with heads that flow well. OHC or Hemi adds to the size of the top end significantly making them less swap friendly.

I’m addicted to these videos and can’t stop rewatching every episode wanting more frequent uploads!!!

LT swapping my c10 currently. The LT was my choice purely because I got the engine for "free". Buddy got it through his job at a service center because it was pulled for a stuck lifter under warranty and was just going to be scrapped, I traded him a shotgun for it. Although he did give me the option of the LT or one of the hundred of SBC shorts he had sitting around, but took the LT because I was sold on the direct injection, high flow of the heads, and the 6 bolt mains.

The main downsides to the LT you presented well, and it's as you say the aftermarket isn't there because the engine is still too new.

[eugeniomorales]

Manual transmission LT engines don't have displacement on demand. But imagine using your two feet to drive? Oh the

A few years ago, Petronix had an engine build competition. On team built a 350 cid engine while the other team built a LS 6.0 engine. Both teams had the same budget of 5, 000 dollars, the 350 engine outperformed the LS except for fuel mileage. The price of parts for the older engines were so much cheaper it allowed far more options to build the engine.

There is so much information packed into this video I am going to have to watch it several times.

[Tanner_Teves]

My favorite engine of all time is the LS3. Came in my favorite Corvette generation (C6) and my favorite 4 door sedan (SS). The 5th gen Camaro didn't really speak to me that much (mostly due to that hideous interior) but I still would take it's LS3 over the Mustang's 5.0 coyote.

clearly presented content with no fluff (time wasting rambles). Awesome work quality video!
