For the past 32 years I've only owned Chevy trucks. My first vehicle was a 76 Jimmy with a 350 small block and a turbo 350. My current ride is a 09 Tahoe SSV with a 5.3 and 6L80. However I did pick up a 77 Sierra K15 for a project truck back in November.
Both the gen 1 small block and LS engines are incredible marvels of engineering. They both have their place and I understand why people do the swap.
I'm old school and like the simplicity and ease of working on an old square body. No nonsense, no bull$#!+ extra features or options to cause problems.
I believe old truck old engine.
New truck new engine.
AGREED
I ls swapped a jeep for around 4500 doing all the work myself, it runs amazing and the milage is on par with to 4.0
NICE
They are both great engines. If I had a car with no engine and had to purchase engine mounts, accessories, exhaust, etc., It could definitely make sense to put an LS in it. However, I love spanking the LS powered cars with my 8 second old school smallblock powered '69 Camaro.
Thanks for watching. Have a great weekend!
For the wiring harness for ls....buy a pulled ls with computer and harness for the same price he listed for a harness. You gotta extra motor to play with. I have both old school and new school. I'm a decent tuner and that knowledge will cut cost for ls swaps. Good heads for old school sbc will determine how good it is. So, someone who doesn't understand the operations of an ls will be intimidated naturally. A good set of heads for sbc cost as much as a pulled ls with sensors, intake, fuel rail and injection, computer and harness and accessories at this time. I see both sides having both sbc and ls. But some of those costs you can cut if you are willing to learn the fuel injection and operating system.
Thanks for the tip. Have a great weekend
350 and lm7 engines are the best, you'll never go wrong with either one
have a great day
Spun a bearing on my 406 sbc in my 68 Camaro.Friends tried to talk me into an LS swap.Yaaaa right are you kidding me.Everything already lines up.Even though I ended up putting a lot of machine work into this now 408,bore,line hone,square it,deck it and a new balanced bottom end.When all said and done with gaskets,oil,ex ex ex it came out to $4000.I am glad I did not listen to my friends.I already had manifold,carb,headers,brackets,radiator cooling system,charging system,wire harness ex ex.When we lined up the cars and he had his 5.3 LS to my 408 sbc.This 408 torque kicked in and just pulled on him so hard it wasn’t even funny to him.Long live first gen.First gen FTW!…..Love the mechanical side of things.So much easier to work on.
Looks like your friends got a taste of that classic Camaro power! The 408 sbc reigns supreme. Wishing you all the best for the future!
If you plan to do a solid build whether stock but if you want to make power your going to pay for quality machine work.😎💯🔥💸💸💸
AGREED
I chose the sbc for my s10 for several reasons. 1st being the v8 swap kit was cheaper 2nd was I already had a vortec 5.7 4 bolt. Did the head porting and lapped the valves myself. Screw in rocker studs and beehive springs. I built about 425 hp for less than 3500. Also I think the gen 1 is a better looking engine.
VERY NICE! sounds like it would be a lot of fun to drive.
Got the same thing going in a 1992 s10. 😎♌️❤️💯🔥
NICE
This just made mind up to stay old school, great video!
Glad you enjoyed!
Great video brotha, I myself am an old school kinda guy but I think the ls engines are great for the power and efficiency they provide but building one is still more expensive than building any small block or big block Chevy when you consider everything other than the block. Out here in CA the average cost of a ls swap into a older vehicle is always above $7,000 and that's if you do the work yourself. I myself just bought a early 90's RV for $700 with a big block 454 with only 28,000 miles on it that I'll be transplanting into my 84 C10 😁 I figure when I'm done I will probably be into it for a total of around $5,000. You just can't beat the look, sound and power of a big block Chevy just my opinion
My point exactly, thanks for stopping by to watch. have a great weekend
@@unclebucksgarage7695 brother used to smoke 5.7 LS all day with his 350 SBC when they first came out 1998-2002.
You betcha
@billybobbob3003 I know right, they were not that big of a deal when they first hit the market. Thanks for watching Brother
I still like the simple old school SBC but the LS stuff is nice
You Betcha!!!

Give me old school ANY day of the week!! I have no interest in that LS business.
i have to AGREE with you, have a great week
Don't fear the computer. The LS is just better in every respect. The SBC is the father of the LS. I have all the respect for it but it's time is passed. The lessons learned on the SBC were passed on to the LS and Vortec engines and improved upon. As I mentioned before. You can still carburate an LS if you want to
thanks
@@wolf06291980 wires etc etc. I don't want a computer to get my car tuned and running

The swap mounts can be bought for around $40 now.
Thanks

I have a ls1 in my 68 and am currently looking to swap it back to sb327. Ls should never be in an old car!!
thanks for watching, wishing you all the best
In a square body Chevy you use a 1987 tank for efi a 3 pin heat temperature sensor oil sensor adapter
THANKS FOR THE INFO
Love the video, built a 350 SBC with a 650 cfm carb and a mild cam from summit from an old vortec block my 93 sings the song of muscle 💪🏽💪🏽🔥🔥
LOVE IT, Happy Thanksgiving
thanks for watching
I feel like you pumped the numbers up a bit on the LS side. Such as buying sensors and accessories. And a 1200-1400 holley terminator. For barlely more than your $1200 core estimate i could buy a 6.0 complete with computer, harness, sensors, and all accessories for $1500. From there buy a $350-500 standalone harness for the factory computer and youre golden
Thanks for watching, have a great week.
@@unclebucksgarage7695 I will add a little more to the estimate for my route. After that's said in done you have to pay someone like myself $150 to turn VATS off in the pcm so it will start or $300-500 to tune it if you installed a cam or did any other mods
keep me updated on your build, I am curious.
@unclebucksgarage7695 recently completed an 87 suburban going the route I described. Currently putting a GM performance parts 495hp/LS3 in a 68 firebird but that one isn't a budget swap alot of expensive parts on that one
It’s only going to be cheap until the junk yard runs out of LS motors. Remember they stop making the LS MOTORS. If you do a max effort, build on an LS aftermarket, everything you might as well build a BBC it’ll cost you less and make a hell of a lot more power.
I went with an old school 400 in my ‘85 GMC
NICE, I appreciate you watching. Have a great week.
OG Small block 350 all the way. (For me,my opinion only) love the Video comparison.
Thank you very much!
I got a sbc 355 with duel quad carbs. For my street c10 that’s all the power I could ask for
YOU BETCHA!!!
I'd go with a World Products Motown SBC/LS block (small block on the bottom, LS on the top) - best of both worlds...
Nice idea, have a great week
I think you just changed the direction of my whole build.
LOL have a great day
I love the torque the sbc puts out!!!!
❤❤
so do I. Have a great weekend!
Big Block+Box= Perfection.
NICE!!!!
Bought a 78 c10 that’s been sitting for 15 years changed the battery starts right up I’ll stick with the 350 small block one day the c10 will haul my ZL1
I Agree!
thanks for watching
Love my gen 2 SBC LT1. It does cost to work on it and build it but still cheaper.
Very nice!
These engines are definitely underappreciated. I put a carb swapped low mile junkyard LT1 in my '78 El Camino. Less than $1k all in. Way less than putting aluminum heads and a roller cam in the tired old 350 or doing a junkyard 5.3ls swap. Makes good power too. The carbureted manifold really wakes up these motors.
@@edf5967 I just rebuilt mine recently, it came in my 94 Z28 I bought for $1500 and when I got into the motor, I realized it had a 400 Eagle crank, forged pistons and rods, hot cam, billet welded oil pickup, and overall a very clean engine. The OD didn’t work and was stuck at 253k so I figured it was old and needed freshened up but I was shocked it looked new. I changed the gaskets, plugs, water pump, msd optispark, radiator and mounts, had it machined and heads rebuilt with a little bigger springs and new valves, bought a fresh T56 to hook to her and man, she pops wheelies now. Still cheaper than going all the way with an LS. Probably should have put a fresh rear end under her because I’m not sure if it will last now. I was thinking about converting to a carb too.
THANKS!
My friend has an s10 with a 350 . He's did a some work to the truck such as new brakes , wheels and tires, but the engine is stock as far as he knows. I'm here to see if I want to rebuild that 350, or LS swap it. He was told that 350 was from a vette, but we haven't checked the numbers yet.
So,,,what is your question?
I think it depends on your application. Plus, what you already have access to. If I’m building a car/truck for the strip, I’ll probably head for an LS. If I’m staying on the street or cruising, and I already have the SBC in the vehicle, I’m staying put. My project is an ‘03, and came with the LM7, so naturally I’m sticking with Gen III LS. So, for me, it’s about dancing with the girl you brought with you, lol.
Absolutely, choosing the right engine for your project is crucial. It's all about what works best for your goals and setup.
It's not easy or cheap to do it right. I am doing a LS3 in a 77 Trans Am and it is taking me a lot longer than I thought.
Yes Sir
Should've kept that poncho under the hood of that t /a
Wow that's gay you don't deserve a trans am
Not to mention the brain and stuff for the ls
agreed
Might as well buy a car or truck with all the parts you need just a transplant no problem for seasoned mechanics much cheaper in long road...
Thank you for the suggestion! It's always good to consider different options when it comes to car repairs. Buying a car or truck with all the parts needed can definitely be a cost-effective solution.
I have a 383 sbc with a th350. Everything is nice. But as ive gotten older. Id probably go LS and overdrive for more comfort. And definitely much less power😂😂😂😂
Fair enough!
How is a radiator 3x more for an LS? Heat is heat and hoses are hoses, dude.
THANKS FOR WATCHING
Just bought an 88 k5 350
TBI that I daily and have had an 80 trans am with 350 SBC from a 69 Camaro . Everyone says to LS swap. Why? They both Start right up and go. Do I want more power from the TBI sure but it’ll be cheaper to rebuild what I have that’s known to last. Oh and less wiring
Have to agree with you. Have a great weekend
I wonder if it would just be easier doing a big block vs LS. And which one would work better
Good question
not a bad idea. Have a great weekend
The funny thing is most of these new generations don't know how to work on a carburetor
yep
Engine mounts for the LS swap generally $65 that are adjustable.
Some Companys
thanks for watching
400 hp isn't much
< 500 hp...you can get an entire vehicle to swap a LS and make more power (will cost more, but 100 more hp easy to achieve
>500 hp...SBC is the way to go hands down no argument
thanks for watching, Have a great week
Why didnt you talk about trans. Assume you have th350, its just not going to get abused over 400. If you want 400 a 6.0 drops in with minimal effort with a 4l80 for 1200 low miles on both. Mounts are like 150 200 for the trans mount, already comes with harness and ecu and you're over that 400 spot. Not to mention, make 400 and get 24mpg at the same time lol its just not the same. Junkyard life
Another thing, coolant fans won’t cost you that much, why would you need to replace the radiator? Also what vehicle would you putting it in? Factory EFI? Aftermarket EFI? Or Carb? (LS). Also keep in mind the only LS that you can find in the JY that will have 400hp stock at the flywheel is a 6.0. Now you talking money, more than you put down.
Happy Holidays
thanks for watching
Do your own mounts
Mounts???
@unclebucksgarage7695 Trans and motor
Take that two grand and buy a holley sniper EFI or whatever plus 180 degree headers, which to choose?
lol Have a great week
thanks for watching
Progressive boost and stuff is fun to mess with. I'd honestly take a big block chevy over both
Yes
Have a great weekend
Straight air intake way better.
Maybe
Your a little off on your prices depending on what you put it in. For a lemans oil pan is 300 motor mounts are 150 gages will work with the factory gages you can use the stock computer can use stock rad intake is 400 I went carb.you can still use the stock computer for timing only. Only 2 extra sensors crank and cam.you can get a 5.3 for 250 from a yard headers for decent ones are around 300. I ran both stick efi and carb. If you run the stock efi then your not buying a carb or intake. It cost me about 1700 for motor and install stuff. Can use all the stock brakets from a lm7. I'm no hyped ls guy the only reason I did the swap was cause my 455 needs rebuilt and pontiac stuff cost way more then chevy stuff. I had a 72 455 in it and I put a toqurestorm supercharger on it its a smog engine and the straight out of the junkyard engine with no supercharger on had more power then the 455 yeah makes no sense how. Yes the ls do last a lot more miles but they have there own problems like filling the intake with carbon and sucking oil from the pve and rusty blocks. So in the end I'm still not sure to rebuild the 455.i know the ls will be cheaper to rebuild. I may put a chevy gen 1 350 in I'm still deciding on which way to go. You can dump the same amount in any engine for it to be what you want. Yes less machine work for the ls and they have a better bottom end. Another reason I did the swap if I blow up the 5.3 I can just get another one cheap. If I blow up the 455 it cost a lot to get a rebuildable core.
great info, thank you very much
Thanks for the Info, Have a great weekend

What about the gas prices and the mileage at a 1.50 per litre and the difference between a us gallon and a canadain gallon 3.78 litres 4.54 litre s for a gallon in Canada? And can’t forget the driveability of efi lot less dicking around the a carb

HARRUMPH HARRUMPH!!!

The reason people go for LS is they’re cheap, readily available, but most importantly, they can handle a lot of power, reliably, through forced induction in 100% stock configuration. Skirted block with 6 bolt mains and factory heads that flow better than most aftermarket SBC stuff.
You can buy a complete iron 6.0, intake to pan with harness/ecu, toss in a Cam and springs. You have an easy 500 crank for well under $2,000
thanks for the info, have a great weekend
If the 6 bolt main and skirted block it’s so great ,, how come the aftermarket LS block have the skirts cut off and they use a splayed 4 bolt mains. Only thing good on an LS motor are the heads and big cam core, the rest is junk !!
thanks
Love some SBC, but they dont sell brand new GM bare blocks anymore. You have to buy a $3300K Dart block or whatever if you want a new block.
Still plenty good cores out there
I agree with Grant, Still plenty of cores out there to be used. wishing you all the best for the future
thanks for watching
You can build a 383 stroker for $1800 for everything.
Yep
Dang who I need to go to? Bc it’s a guy trying to charge me 6k for the whole build
You're ignoring the fact that 1) the LS can be carbureted to eliminate sensors 2) if you're buying a used LS it usually comes with the computer and harness. 3) the radiator in your current project will probably be fine with the LS since it runs cooler.
where are you getting all this money for machine work on an LS? A simple tune on a truck motor will hit 400HP without machining or headers. I mean, yeah, if you want to go stupid and buy the most expensive crate motor LS then yes it will be expensive. But you're being disingenuous by mixing the most expensive options with a used motor.
The other consideration is your SBC will get 8-10 mpg at 400HP while the LS will get 18-20
THANKS FOR WATCHING, Have a great week
@@unclebucksgarage7695 You too, man.
Very true I totally agree
LS motors have a lot of inherent problems that no one wants to talk about , simply because there still abundant in junkyards. And there’s company’s making big money on aftermarket parts for them , so your never going find anyone say anything bad about them. So you really want to go though the motor to make sure everything is good. In my 38 years of racing and wrenching for a living I’ve never seen an engine destroy cam bearings like an LS motor.
@@glennborek2359 certainly, no engine is perfect. They all have their quirks and issues. But pound for pound and dollar for dollar you just can't beat an LS
SBC all day for me and FYI is not an ls if it's not all aluminum block and heads not just heads and iron block dont work that way ls fans 😂😂.

It’s pretty nasty Chevrolet racing rods for connecting rods broke the automatic for the second time I’m currently in the process of changing it over to a standard And putting a limited slip 373 rear end in it should be lots of fun Definitely be way better than the 308 that was in it Because I called the one wheel wonder lol

I still don’t get the point of swapping to LS engine. You have to swap that plus the harness ECU computer and bunch of other stuff, on gen 1 engines everything is so simple. I was about to put an ls on my c10 but instead i went with a crate 454. Easiest swap ever
Agreed 👍

LS engines are not as fun to tinker on in a classic. Take this from a guy that LS swapped his chevelle. Then once gou get it in there you realise how ugly it is then you spend another 1k to try to get it to look halfway decent. Really it all depends on what your goal is.
Thanks for sharing your experience with LS engines in a classic car! It's always interesting to hear different perspectives on engine swaps and the challenges that come with it.
thanks for watching
Your math is wrong. you lowballed the sbc and highballed the LS (by accident right??) sbc $4775 - LS $6450. ......$1675 difference (and the LS does not need all new sensors and harness) Then in the end you have a farrrr better and more reliable motor with the LS

LS is expensive and risky. If it's just a cruiser buy a 350 crate motor and be done with it.

Your math ain't mathin'. You're comparing making 400fwhp in a 350 to the cost of LS swapping a vehicle? 😂 What about the guy that ownes a 2002 chevy Silverado that wants 400hp al he needs is $500 cam kit and a tune. If he wants to spend $4500, he can have 650hp at the tire. You ole boys will do anything to keep your carbureted 350's relevant
Have a great week
Crazy how much bad information there is these days
lol have a great day
You lost me in first minute of the video.....Ive done both on many cars, hp per dollar the gen 3/4 ls is waaaay cheaper. Under 1200hp LS wins the price per hp by alot. Over that it all becomes about the same. If it cost alot of money for you to swap a ls into your car it was by choice...because you bought parts for beauty or personal preference reasons. transmission mounts are same because the transmission is the same. Because the 4l60 is the exact same as a 700r4. motor mounts are same because you just by and adapter plate for like $40. I mean you literally told me you dont know shit about ls swaps in the the first minute of your video. And yes you can quite literally go to junkyard and buy a pullout for $200 5.3 that makes waaay more hp then a stock gen 1 anything. So you are already ahead of the curve by like 100-120crank hp. You have to buy a whole top end package to compete with a STOCK 5.3. And thats not even the best ls engine to get. If someone is starting off with say 6 cyl camaro/nove/whatever or a even a 4 cyl/302 foxbody. The ls swap is waaaaaaaaaay cheaper then throwing a sbc or 351 in the fox. And stock for stock itll be way faster. Youd have to throw an extra 2-3k at the older motors just to maybe keep up with the stock 5.3 with a small cam. 6.0 ls its not even fuckin close....and the used parts for ls family is HUGE...
THANKS FOR WATCHING
Don't know how to adjust your lifters properly.
going to make that video soon
It's clear that you have absolutely no idea what you're talking about. For $6500 you can take a junkyard LS and push well over 650hp, realistically probably closer to 800hp. Sorry old timer
