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 $5,000. You just can't beat the look, sound and power of a big block Chevy just my opinion
Maybe I've had bad luck. But every big block Chevy I have had, has broken something. Small blocks............NADA. I did like the OLD SCHOOL LS7 big block though. Buddy in high school had one. Scary engine.
For the past 32 years I've only owned Chevy trucks. My first vehicle was a 76 Jimmy with a 350 small block and a turbo 350. My current ride is a 09 Tahoe SSV with a 5.3 and 6L80. However I did pick up a 77 Sierra K15 for a project truck back in November. Both the gen 1 small block and LS engines are incredible marvels of engineering. They both have their place and I understand why people do the swap. I'm old school and like the simplicity and ease of working on an old square body. No nonsense, no bull$#!+ extra features or options to cause problems. I believe old truck old engine. New truck new engine.
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.
Oh man ! I almost bought a 71 GMC C15 today with an LS3 in it !!! All of the body was pretty much shot ! So glad I walked ! Oh yeah, gimme old school, simple !
In 1976 I installed a 1972 L48 out of a 1972 Camero into a 1971 FJ40 Land Cruiser. 250 hp with a 2 barrel Rochester. It had 30,000 miles on it. I am still driving it today with close to 200,000 miles. It has never been apart. I did replace the timing chain and installed an HEI tach drive distributor. 100% dependable.
I had one of those l48 engine came out of a Corvette 1980 it would pull a mark at 30 mile per hour in c1500 86 good engine.put some vortec head on it an ride
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
Great video, I will keep my SBC. Currently in the process of swapping out the carburetor, intake, distrbutor, all gaskets, valve covers, wires, plugs, thermostat, water pump etc. I am ready to get my hands dirty and keep it alive. I love watching LS videos and seeing people enjoy them, but I will never go that route. That's why I have my Dodge Charger and a Nissan Maxima. Hop in and go! Great breakdown. LOL @ start a fight LOL
I bought a 2007 Escalade that was wrecked with the 6.2 awd system for $1200, did a frame swap with my 79 Chevy, threw a cam, lifters and spring kit for $1100, tuned the computer for $250, I used everything from the Escalade, didn’t had to buy anything. Truck is making 490hp and handles like a new truck cause pretty much it is.
I've had lots of both engines... love em both!!! I'd have to say for several reasons I'd take a 2014 or newer 5.3L 345HP stock or the 6L with over 400HP... that's enough power without upgrades for a guy and you can buy a complete engine from the auto wrecker cheap lol done
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.
If you pull the complete swap from a donor vehicle like a pickup truck or SUV, most of the cost is eliminated. Sure, it's more work initially, but once you get it done, it's just as easy as replacing your SBC if your engine blows up. The vortec gives you more power than the SBC at no additional cost.
Had them both and like them both. I have a solid roller 10.8-1 compression old school 388 Stroker in my full weight C3 vette and I drive it everywhere and it ran a 10.86@122 on the motor and has been in the car since 2009.
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.
I like your video and you broke it down . for me it is all about simplicity , I am not making a living winning races so I personally am happy with more than stock power but still want to go on long trips . I want to carry a minimum amount of tools and if I break down I want to fix it fast and cheap without any electronic diagnosis or expensive parts . Plus I like the looks of the Old school stuff . I have had an LS and yes I liked it , I just think it is a matter of choice for me . Old school !!!
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.
I did the LS thing on my 67 Camaro. Small block Chevys for me from now on. I don’t want to be one of those folks that break down on the side of the road, opens the hood, and tries to twist the battery connector and hope that works. Great episode.
what about the wiring where it goes through the ignition block on the fire wall that goes to the ignition switch wont the wiring harness have to be changed too i dont know if the original ignition system will work if then you would have to switch over to an intake with a carbureteur on the ls !!!
I love my rebuilt 1970 c10 it’s just the starting when the engine is cold. It takes forever versus Ls starts right away. But yet I’m very happy with it
I like the gen2 SBC motor. The Vortec 350 makes really good power for lil money. But take the block an heads an make a 388 ci. Stroker with the roller cam motor will make even more power.
I refer to the late model 5L and 5.7L vortec engines as gen 1.5 and the 90s lt1/lt4 as gen 2. I like the gen 2 lt1s, the blocks have proven to be much stronger for me, the stock heads can be ported to flow very well, just address the opti spark. You can put a crank trigger, gen 1 efi single plane intake elbow throttle body, cam sync and use the LS harness and 411 ecm , coil on plug for a more budget deal, same can be done on a gen 1.
@@frigglebiscuit7484 And its said the iron lt1 is better in stock form than the aluminum lt1. There are cnc programs for the alu heads that result in pretty good numbers across the bench. Ive seen a few sets of lt4 heads for sale reasonably priced lately.
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
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
@@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
@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 personally prefer the small block in most applications due to simplicity i daily drove one for two years because of the pandemic and it worked really well for me with the multitude of issues i had with it it was never so bad that I could not get around it. An LS platform would absolutely have been more convenient and reliable over my worn out 283 but when I ran into problems such as heater hoses and power steering lines popping getting what I needed off the shelf was definitely easier over having an LS swap where I would have been looking for something likely would need modifications to fit.
I ran a 406 sb back in the day 30 over with flat top pistons 350 camel hump comp 280 magnum hydraulic holley 750 vacuum edelbrock dual plane and it was a stump puller it kinda ran out of breath at about 5-55 but it wasted no time getting there. There really is no replacement for displacement. That being said the LS blocks are superior to the gen1 sbc the stock blocks can handle way more than a gen1 and that would be the main reason for doing a swap
Im a ford Mustang fan all my 43 years. I own a built procharged 3.7 Mustang Car runs a 11.5@120 on only5-6 psi. My wife and daughter are wanting a car to Race/weekend drive. We decided on a 88 black step side Silverado. I debated going Ls. I ended up picking up a set of cheap Chinese SBC aluminum heads had machine shop go over them, eagle 383 crank, rods, pistons set. Mildish Comp cam .500/.500 had machine shop install cam bearings bore block. I assembled everything. Including all parts and machine shop work I was in $2500-2750. Truck dyno 313 whp @5900 /390 wtq @ 4800. Truck runs a 12.5 @ 110. Here in hot Florida. 355 gears, 700r4, 2400 stall Holley sniper efi. Wife and daughter love it. Only issue I'm having is my wife wants to paint truck pink. Not happening haha.
Both have their place. 400hp makes a good cruiser, only reason to go ls in my thoughts is if you want boost. And to make 700 hp daily driver. More than one way to skin a cat. There is many nice stand alone tbi systems that I'd want on either one that you still get to play with and tune. I dig the old school, got a small block myself but there is a place..all toys cost.
I liked your video. Have an 89 Silverado stepside 4x4 with a bad motor. Have gone back and forth with what to do with it, rebuild the 350 or junkyard LS swap. After watching this video I'm 100 percent rebuilding the motor- have to see what's salvageable but in the end I believe will be a better deal than LS swapping it. Had a nice RV cam in original- miss it so much. Appears if I save up 5k I will be good to go for rebuild and some nice upgrades like headers ect.
I’m doing a complete LS swap wiring harness and transmission. I’m leaving it stock as that is about 150hp more than the original sbc. It should come in under $2500
Im ditching the 5.7 vortec sbc in my 98 Z71 for a cammed lq4 6.0 vortec being set up for towing... I love the LS motors so easy to make power so much can be done with them and I hate carburetors so naturally I also love the fuel injection on the ls aswell 🙂
Put a cam with the same specs & you not have 100 hp more. Not with aluminum heads you won't. This guy was very generous with cost as the electronics alone(new) w_ the intake, throttle body upgrade plus just the wiring harness can buy you a new carb
My buddy is financially well off and prefers LS engines but I’m a poor guy with a classic collectible truck and not a pro racer, so for me the Mighty Mouse is perfect!
LS can run a carb just like the sbc.....intake 250.00........msd coil control 500.00... Bang for buck , the carbed ls will make more power in an easier to drive package . The valve angles are more efficient , so you can run a milder cam and make more power . Here is my experience and it really opened my eyes on ls potential . I have 2 cars , a 68.camaro and a 72 camaro. The 68 was built to run hard and go low 11s . The 72 was built to be an all around cruiser , but with good power. The 68 had a built 406, 220cc aftermarket heads, 11.4 comp, big solid cam , etc . At 2900lbs , it ran 11.30 at 120 . The 72 had an ls3 w a simple conversion to carb like I described above , a set of headers, and a very streetable , small cam . At 3400lbs the 72 ran 11.60 and 120mph . The 68.was setup for hooking at the track w 4.10 gears and had no accessories on the engine. The 72 had ac and ps w 3.42 gears and was designed to be a multipurpose car. With limited traction , the 72 ran within 3/10ths of the 68 that hooked solid. The ls setup was a mild street build and the 68 was set up for the 1/4mile. The 72 was 400 lbs heavier and anyone could get in it and drive it like a new car . The ls costs about the same if you build a gen 1 to make power and carb a performance ls engine w a street cam. The ls makes power very easily and in a much milder package, will run with the sbc that is difficult to street drive by your average person . I like both, but the potential of the carbed ls is hard to.ignore . Just because the ls comes w an ecu and plastic intake doesn't mean it needs that to outperform a similar carbed sbc.
You'll never change the opinions of these old heads lol. I'm a LS guy from experience myself. The sbc (especially pre vortex) gets very fragile after 200-250k miles. Most well maintained LS motors run like new until they reach 400k-500k miles. Then you should expect gasket and manifold replacement.
Realistically speaking getting the project car done an working properly in a timely fashion the sbc wins hands down. It’s absolutely bare bones simple an I’ll take that every time.
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.
Definitely SBC! Put the early generation of throttle body injection on it. Ultra reliable, as long as you are not trying to build a top race motor. Stay right at or under the 400hp and they will run all day every day. They make great cruising motors that are clean to look at and can be worked on by most every shade tree mechanic out there.
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😂😂😂😂
I like the simplicity of a carburetor. Once you install a fuel regulator and a Wide band gauge it’ll make your carburetor run better once it’s dialed in. My Chevy 350 on my 75 K5 runs like it’s EFI. I don’t mind the cold starts. It will still start up. It may take a few cranks but it doesn’t have a problem not starting. Plus if It breaks down the road it’s much easier to fix. Doesn’t need a O2 sensor replacement or doesn’t need a ECU if it overheats.
Great insight-unfortunately, everyone will have their own insight on which is better. . . I have a 67 Firebird with a 455 (Pontiac) w/ minor cam and polished heads (all iron) + TH400, and folks asked me to just LS it. Why spend the $$$? My old school setup works, and I'm happy with the simplicity, with plenty of torque to knock the tires off at anytime. Enjoy your ride, spend within your means, and have fun.
Great video! Totally agree except I suspect you could do it with a set of cast iron vortec heads. Although perhaps you may have to do some work to them to handle the cam that would take you to 400 horsepower. I don't mean porting and 202 valves but springs and such
I’ll Take my LS any day, 400 horse power 17 mpg at 80 mph. With a junkyard motor. Been on 4 power tours with a LS powered car. As stated earlier they typically don’t leak. To each their own I guess.
Swapping in an LS is only financially feasible when swapping it in stock using a running donor. As soon as you want more power the sbc is just way cheaper. However if you want insane amounts of power (600+hp) for RACING APPLICATIONS the ls might hold up better. I still use old school sbc on street engines. You need torque on the street, and high rpm hp at the track. Great video 👍
5.3-6.0 complete Motor $500 + sloppy cam kit $300= 450hp. The worst ls heads outflow all SBC heads. Why do you feel it is more expensive to chase power with the LS? Bc of the fuel system upgrades needed?
I’ve got the factory 350 in my ‘78 k20 and it’s pretty gutless. I’m going to put a 5.3 in it next year sometime. More power and better gas mileage. I don’t mind working on engines. I’ve worked on everything. I do like the old engines but you just can’t beat an ls. The cold starts in -50 degrees is pretty much the main reason why I’m going with the ls.
I WOULD NEVER SWAP AN LS INTO AN OLDER CLASSIC, I SPEAK FOR THE SAME GROUP OF GUYS THAT WOULD NEVER LOWER A 4×4, NEVER PUT 20" RIMS WITH LOW PROFILE TIRES ON OUR TRUCKS OR HOTTODS.
First off I want to say great video I have a story for you I will try to keep it short. I have a 1998 Chevy Silverado 4x4 so it had the 5.7 vortex in it I got so tired of the sensors go out on it every other week grrr. So I decided to buy a 1978 4 bolt main 350 from a guy on Craigslist for $300 and rebuild it I asked my machine shop what do i have to do to get 400hp out of her they said we'll you can spend $800-$1200 on a pair of aluminum heads or do a valve job on your vortex heads you all ready have for $500 I said OK let's do that border it out 30 over comp cam vortex heads aluminum intake from summit Holly carb ect. All in I was at $4500
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
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.
One last question Uncle Buck. I have all the parts to do the floors rockers etc, but now LMC sells a NEW product. A complete drop in floor for square body 4x4's. What would you use?
Nothing is cheap about any hobby. Especially racing. I’m a Ford guy, so If I’m going to do a late model swap, it’s going to be Fords new Godzilla 7.3L engine. David Wolf made 670hp NA and 650 ft lbs of torque for under $6K including the engine core. That’s aftermarket rods and pistons, BTR camshaft, Johnson LS7 lifters and a BTR intake. A 408 Ls would set you back about $10-12K for the same hp and 100 less ft lbs of torque. This engine swap would be worth the extra cost for the potential power output vs a SBF engine. Now if I was going to do a SBC vs Ls and my vehicle already has a SBC, I’m going to stick with the SBC for simplicity. You all know it’s about what are your current goals and future goals for the build. This could be a never ending argument for car enthusiasts.
@ they keep their hoods closed after getting gapped by Ford power. Kinda like most of the Chevy powered mustang in my area getting gapped by our NA 418-W. They accused us of hiding nitrous. It looked like a Pink Floyd laser light show with all the flash lights. Skip White Chinese SBF cylinder heads that I reworked and a hydraulic roller camshaft such a simple build killing the Chevy boys. I’ll never understand why you Chevy guys get so but hurt. We dominated the low 6 second cars with a ford.
The block is a function of bore and stroke and the only significant difference is aluminum or iron until you exceed 700hp or 500 ft lbs. Only then does a girdle come into play. Everything else is a matter of what the heads will flow.
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 appreciate both, the ls fuel-injected and sbc carbureted engines. They are relatively easy to adjust and tune using a screwdriver or a computer, and there are many stock parts and aftermarket upgrades available. In terms of fuel economy, I would recommend an LS engine, while for a nuclear apocalypse scenario, I would choose a carbureted small block Chevy (SBC) engine.
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.
Don't know where you buy cheap LS engine, not at a junk yard, $1500 at the cheapest, I want to put that in a square body, ohhh, no warranty if it's not going in correct application
Ls swap into square body ...low milage tahoe smashed by a tree....750 bucks.... motor mount plates 25 bucks ...high presure fuel pump and lines 100 bucks...flywheel 135 bucks....vats tuned computer 100 bucks....do the wiring yourself it's easy....And twice the mileage of the 454 I took out......

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

Maybe I've had bad luck. But every big block Chevy I have had, has broken something. Small blocks............NADA. I did like the OLD SCHOOL LS7 big block though. Buddy in high school had one. Scary engine.
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
Has your six speed blown apart yet? I'm not joking or making fun. Many of my friends have "LOST" that tranny.
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
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
now you get to sit down for many many hours and pick apart that tumor of a wiring harness, and then you have to get your ecm flashed to remove vats.
@@frigglebiscuit7484is that all? Lol 1994 k1500 4x4 I'm thinking about putting ls motor
Well said
The less wiring and electronics the better. I only worry about grounds. But to each his own. HAVE FUN ! That's what it's all about.
350 and lm7 engines are the best, you'll never go wrong with either one
have a great day
I love the torque the sbc puts out!!!!

In 1976 I installed a 1972 L48 out of a 1972 Camero into a 1971 FJ40 Land Cruiser. 250 hp with a 2 barrel Rochester. It had 30,000 miles on it.
I am still driving it today with close to 200,000 miles. It has never been apart. I did replace the timing chain and installed an HEI tach drive distributor. 100% dependable.

Great video, I will keep my SBC. Currently in the process of swapping out the carburetor, intake, distrbutor, all gaskets, valve covers, wires, plugs, thermostat, water pump etc. I am ready to get my hands dirty and keep it alive.

I bought a 2007 Escalade that was wrecked with the 6.2 awd system for $1200, did a frame swap with my 79 Chevy, threw a cam, lifters and spring kit for $1100, tuned the computer for $250, I used everything from the Escalade, didn’t had to buy anything. Truck is making 490hp and handles like a new truck cause pretty much it is.

I've had lots of both engines... love em both!!! I'd have to say for several reasons I'd take a 2014 or newer 5.3L 345HP stock or the 6L with over 400HP... that's enough power without upgrades for a guy and you can buy a complete engine from the auto wrecker cheap lol done
THANKS FOR WATCHING
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?
If you pull the complete swap from a donor vehicle like a pickup truck or SUV, most of the cost is eliminated. Sure, it's more work initially, but once you get it done, it's just as easy as replacing your SBC if your engine blows up. The vortec gives you more power than the SBC at no additional cost.

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!
I like your video and you broke it down . for me it is all about simplicity , I am not making a living winning races so I personally am happy with more than stock power but still want to go on long trips . I want to carry a minimum amount of tools and if I break down I want to fix it fast and cheap without any electronic diagnosis or expensive parts . Plus I like the looks of the Old school stuff . I have had an LS and yes I liked it , I just think it is a matter of choice for me . Old school !!!
AGREED! THANKS FOR WATCHING!
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
A 5.3 big cam and headers alone will put you at 430 to 450 all day long.
@@Dboyquicks10 I love those 4 bolt vortec blocks. Much easier to run roller lifters.
I did the LS thing on my 67 Camaro. Small block Chevys for me from now on. I don’t want to be one of those folks that break down on the side of the road, opens the hood, and tries to twist the battery connector and hope that works. Great episode.
THANKS FOR WATCHING. MERRY CHRISTMAS!
what about the wiring where it goes through the ignition block on the fire wall that goes to the ignition switch wont the wiring harness have to be changed too i dont know if the original ignition system will work if then you would have to switch over to an intake with a carbureteur on the ls !!!
YES TO ALL OF THE ABOVE
I love my rebuilt 1970 c10 it’s just the starting when the engine is cold. It takes forever versus Ls starts right away. But yet I’m very happy with it
THANKS FOR WATCHING
I like the gen2 SBC motor. The Vortec 350 makes really good power for lil money. But take the block an heads an make a 388 ci. Stroker with the roller cam motor will make even more power.
NICE!!!
I refer to the late model 5L and 5.7L vortec engines as gen 1.5 and the 90s lt1/lt4 as gen 2. I like the gen 2 lt1s, the blocks have proven to be much stronger for me, the stock heads can be ported to flow very well, just address the opti spark. You can put a crank trigger, gen 1 efi single plane intake elbow throttle body, cam sync and use the LS harness and 411 ecm , coil on plug for a more budget deal, same can be done on a gen 1.
@@stevenbelue5496 the vortec head is just the iron lt1 head with the regular cooling design put back.
@@frigglebiscuit7484 And its said the iron lt1 is better in stock form than the aluminum lt1. There are cnc programs for the alu heads that result in pretty good numbers across the bench. Ive seen a few sets of lt4 heads for sale reasonably priced lately.

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
Hi Again Uncle Buck! looks like you might be a Navy vet too? Sending Love, Light and blessings to you my brother! Cheers from Motown/Dearborn!
THANK YOU VERY MUCH BROTHER
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.
Fella you just helped me make up my mind. Gonna SBC my '89 S15. Thanks for the info.
Glad I could help! THANKS FOR WATCHING
Where do you buy car parts this cheap? I have never seen an LS for under $2000
Oklahoma
YEP, pick your parts here are 500 to 700 for a 5.3
I personally prefer the small block in most applications due to simplicity i daily drove one for two years because of the pandemic and it worked really well for me with the multitude of issues i had with it it was never so bad that I could not get around it. An LS platform would absolutely have been more convenient and reliable over my worn out 283 but when I ran into problems such as heater hoses and power steering lines popping getting what I needed off the shelf was definitely easier over having an LS swap where I would have been looking for something likely would need modifications to fit.
AGREED, THANKS FOR WATCHING
The old-school small block Chevy is still relevant in 2025.
THANKS FOR WATCHING, HAVE A GREAT DAY
Thanks for the information, this helps a lot. My c20s engine is smoked and was considering swapping it. Think I’m gonna stick with a 350

I ran a 406 sb back in the day 30 over with flat top pistons 350 camel hump comp 280 magnum hydraulic holley 750 vacuum edelbrock dual plane and it was a stump puller it kinda ran out of breath at about 5-55 but it wasted no time getting there. There really is no replacement for displacement. That being said the LS blocks are superior to the gen1 sbc the stock blocks can handle way more than a gen1 and that would be the main reason for doing a swap

Both have their place. 400hp makes a good cruiser, only reason to go ls in my thoughts is if you want boost. And to make 700 hp daily driver. More than one way to skin a cat. There is many nice stand alone tbi systems that I'd want on either one that you still get to play with and tune. I dig the old school, got a small block myself but there is a place..all toys cost.

I liked your video. Have an 89 Silverado stepside 4x4 with a bad motor. Have gone back and forth with what to do with it, rebuild the 350 or junkyard LS swap. After watching this video I'm 100 percent rebuilding the motor- have to see what's salvageable but in the end I believe will be a better deal than LS swapping it. Had a nice RV cam in original- miss it so much. Appears if I save up 5k I will be good to go for rebuild and some nice upgrades like headers ect.
NICE, Have a great week
I’m doing a complete LS swap wiring harness and transmission. I’m leaving it stock as that is about 150hp more than the original sbc. It should come in under $2500

Im ditching the 5.7 vortec sbc in my 98 Z71 for a cammed lq4 6.0 vortec being set up for towing... I love the LS motors so easy to make power so much can be done with them and I hate carburetors so naturally I also love the fuel injection on the ls aswell 🙂
Put a cam with the same specs & you not have 100 hp more. Not with aluminum heads you won't. This guy was very generous with cost as the electronics alone(new) w_ the intake, throttle body upgrade plus just the wiring harness can buy you a new carb
My buddy is financially well off and prefers LS engines but I’m a poor guy with a classic collectible truck and not a pro racer, so for me the Mighty Mouse is perfect!
YOU BETCHA! THANKS FOR WATCHIN AND MERRY CHRISTMAS!
LS can run a carb just like the sbc.....intake 250.00........msd coil control 500.00...
Bang for buck , the carbed ls will make more power in an easier to drive package . The valve angles are more efficient , so you can run a milder cam and make more power .
Here is my experience and it really opened my eyes on ls potential . I have 2 cars , a 68.camaro and a 72 camaro. The 68 was built to run hard and go low 11s . The 72 was built to be an all around cruiser , but with good power. The 68 had a built 406, 220cc aftermarket heads, 11.4 comp, big solid cam , etc . At 2900lbs , it ran 11.30 at 120 .
The 72 had an ls3 w a simple conversion to carb like I described above , a set of headers, and a very streetable , small cam . At 3400lbs the 72 ran 11.60 and 120mph .
The 68.was setup for hooking at the track w 4.10 gears and had no accessories on the engine. The 72 had ac and ps w 3.42 gears and was designed to be a multipurpose car.
With limited traction , the 72 ran within 3/10ths of the 68 that hooked solid. The ls setup was a mild street build and the 68 was set up for the 1/4mile. The 72 was 400 lbs heavier and anyone could get in it and drive it like a new car .
The ls costs about the same if you build a gen 1 to make power and carb a performance ls engine w a street cam. The ls makes power very easily and in a much milder package, will run with the sbc that is difficult to street drive by your average person .
I like both, but the potential of the carbed ls is hard to.ignore . Just because the ls comes w an ecu and plastic intake doesn't mean it needs that to outperform a similar carbed sbc.
HAVE A GREAT DAY
You'll never change the opinions of these old heads lol.
I'm a LS guy from experience myself.
The sbc (especially pre vortex) gets very fragile after 200-250k miles.
Most well maintained LS motors run like new until they reach 400k-500k miles. Then you should expect gasket and manifold replacement.
Realistically speaking getting the project car done an working properly in a timely fashion the sbc wins hands down. It’s absolutely bare bones simple an I’ll take that every time.
THANKS FOR WATCHING HAVE A GREAT DAY
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!
Love my 427 sbc old school high HP
Definitely SBC! Put the early generation of throttle body injection on it. Ultra reliable, as long as you are not trying to build a top race motor.
Stay right at or under the 400hp and they will run all day every day.
They make great cruising motors that are clean to look at and can be worked on by most every shade tree mechanic out there.
Merry Christmas, Thanks for watching
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!
Jus swap the trans out with a 400 or 700
I like the simplicity of a carburetor. Once you install a fuel regulator and a Wide band gauge it’ll make your carburetor run better once it’s dialed in. My Chevy 350 on my 75 K5 runs like it’s EFI. I don’t mind the cold starts. It will still start up. It may take a few cranks but it doesn’t have a problem not starting. Plus if It breaks down the road it’s much easier to fix. Doesn’t need a O2 sensor replacement or doesn’t need a ECU if it overheats.
AGREED, Thanks for watching
Take that two grand and buy a holley sniper EFI or whatever plus 180 degree headers, which to choose?

Great insight-unfortunately, everyone will have their own insight on which is better. . . I have a 67 Firebird with a 455 (Pontiac) w/ minor cam and polished heads (all iron) + TH400, and folks asked me to just LS it. Why spend the $$$? My old school setup works, and I'm happy with the simplicity, with plenty of torque to knock the tires off at anytime.

Great video! Totally agree except I suspect you could do it with a set of cast iron vortec heads. Although perhaps you may have to do some work to them to handle the cam that would take you to 400 horsepower. I don't mean porting and 202 valves but springs and such

THANKS FOR WATCHING
yeah junkyard motor is a risk, and you aren't getting 400 horsepower unless you swap the cam and some other items etc
😂😂😂😂😂
Swapping in an LS is only financially feasible when swapping it in stock using a running donor. As soon as you want more power the sbc is just way cheaper.
However if you want insane amounts of power (600+hp) for RACING APPLICATIONS the ls might hold up better.
I still use old school sbc on street engines. You need torque on the street, and high rpm hp at the track.
Great video 👍
thanks for watching
5.3-6.0 complete Motor $500 + sloppy cam kit $300= 450hp. The worst ls heads outflow all SBC heads.
Why do you feel it is more expensive to chase power with the LS? Bc of the fuel system upgrades needed?

Nothing compares
I’ve got the factory 350 in my ‘78 k20 and it’s pretty gutless. I’m going to put a 5.3 in it next year sometime. More power and better gas mileage. I don’t mind working on engines. I’ve worked on everything. I do like the old engines but you just can’t beat an ls. The cold starts in -50 degrees is pretty much the main reason why I’m going with the ls.

I have a story for you I will try to keep it short.
I have a 1998 Chevy Silverado 4x4 so it had the 5.7 vortex in it I got so tired of the sensors go out on it every other week grrr.
So I decided to buy a 1978 4 bolt main 350 from a guy on Craigslist for $300 and rebuild it I asked my machine shop what do i have to do to get 400hp out of her they said we'll you can spend $800-$1200 on a pair of aluminum heads or do a valve job on your vortex heads you all ready have for $500 I said OK let's do that border it out 30 over comp cam vortex heads aluminum intake from summit Holly carb ect.
All in I was at $4500
NICE!!!
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

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

One last question Uncle Buck. I have all the parts to do the floors rockers etc, but now LMC sells a NEW product. A complete drop in floor for square body 4x4's. What would you use?
IF ITS BAD ON BOTH SIDES I WOULD DO THAT NEW PRODUCT. EVERYTHING I HAVE GOTTEN FROM THEM HAS BEEN GOOD FITTING QUALITY
Nothing is cheap about any hobby. Especially racing. I’m a Ford guy, so If I’m going to do a late model swap, it’s going to be Fords new Godzilla 7.3L engine. David Wolf made 670hp NA and 650 ft lbs of torque for under $6K including the engine core. That’s aftermarket rods and pistons, BTR camshaft, Johnson LS7 lifters and a BTR intake. A 408 Ls would set you back about $10-12K for the same hp and 100 less ft lbs of torque. This engine swap would be worth the extra cost for the potential power output vs a SBF engine. Now if I was going to do a SBC vs Ls and my vehicle already has a SBC, I’m going to stick with the SBC for simplicity. You all know it’s about what are your current goals and future goals for the build. This could be a never ending argument for car enthusiasts.

Why dont you do what most guys with Fords put Chevrolet stuff that makes it go fast and just make it look like its a ford keep hood closed
@ they keep their hoods closed after getting gapped by Ford power. Kinda like most of the Chevy powered mustang in my area getting gapped by our NA 418-W. They accused us of hiding nitrous. It looked like a Pink Floyd laser light show with all the flash lights. Skip White Chinese SBF cylinder heads that I reworked and a hydraulic roller camshaft such a simple build killing the Chevy boys. I’ll never understand why you Chevy guys get so but hurt. We dominated the low 6 second cars with a ford.
The block is a function of bore and stroke and the only significant difference is aluminum or iron until you exceed 700hp or 500 ft lbs. Only then does a girdle come into play. Everything else is a matter of what the heads will flow.

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 appreciate both, the ls fuel-injected and sbc carbureted engines. They are relatively easy to adjust and tune using a screwdriver or a computer, and there are many stock parts and aftermarket upgrades available. In terms of fuel economy, I would recommend an LS engine, while for a nuclear apocalypse scenario, I would choose a carbureted small block Chevy (SBC) engine.
LOL, AWESOME
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
thanks for watching
Your welcome
Don't know where you buy cheap LS engine, not at a junk yard, $1500 at the cheapest, I want to put that in a square body, ohhh, no warranty if it's not going in correct application
You can put a ls anywhere a sbc will go for under 2500. Cam and turbo if you know how to mig can both be done for less than another 2500
THANKS FOR WATCHING
