The LS will make more power, get better mileage, and start right up in any temperature. It also takes much less skill to freshen up an LS than a SBC. No distributor, carburetor, no timing lights, no jetting, and the way the LS is gasketed is a dream compared to a SBC.

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.

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.

[@USGovsOwnersRtheRealEnemy]

@@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.

[@unclebucksgarage7695]

HAVE TO AGREE WITH YOU

[@wolf06291980]

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

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.

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.

[@inscoredbz]

Sbc is a better looking engine. Parts can be bought from McDonald's drive thru for them. An LS has a strnger bottom end, but thats about the only advantage I've seen. Most people get a junkyard LS, turbo it and a cam swap. Make tons of power. The same thing could be done with a good small block Chevy after putting some good heads on it. A set of dart copies or even better promaxx project x heads. A good roller cam, and you can match the power until you reach the point of block failure. And let's be realistic, the crank and rods in a small block Chevy are not as strong as an LS and neither is the block.

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...

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.

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.

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

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.

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.

[@danielbunk8611]

From the rebuild/regasket section down, you’re completely wrong on the LS side. So many factory parts from your core can be reused. You don’t need crazy cooling system mods to run an ls. The only thing changed about my cooling system on both of my ls swaps is the water pump and the radiator hoses. The factory brackets work perfectly so no need to spend money there. New ac delco sensors are no where near 650. Any aftermarket harness/ecu is going to come with o2 sensor/s. The Holley stuff is just overpaying. Haltech/aces is a much better system which are like $1000 with trans control (which is what you’ll pay for a decent carb, not jimmys vacuum secondary edelbrock). You’re just trying to justify not ls swapping which is fine. But once you realize how much simpler they really are you’ll love it. Turn the key and go, easier to work on (might be a little harder to diagnose depending on your knowledge), more efficient, capable of flowing way more air right out of the box, the list goes on. People don’t only ls swap for the power.

after watching the first minute of this video its clear Uncle Buck has no idea that a junk yard LS with 100 miles plus will run years more under heavy abuse, even with forced induction. Machine shops dont care what the block is, the cost of machining is the same.

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.
