Issues AFTER an LS swap! CAR WIZARD warns what can happen on an LS swapped '73 Corvette Stingray 

On a side note: You didn't kill yourself.

jeffery! u still alive brother?

How is Israel in the Spring Jeff ?

Who killed you dude? CIA or Mossad? Neverminded, those are one in the same.

I'm swapped engines in my Impala but haven't even glanced at my brakes yet. Yanked the straight six out and I'm putting in a mild gen v 454 next week

True dat.

Foreal, reliability.

That’s how I’d deal with it.

@Joseph Pearcey yeah the injection makes more power and uses a shit tonne less fuel and improves driveability no end. But yeah. Stick with 1930s tech.

@@sugarnads no it does not make more power. It may be more tuner friendly because you have a laptop but that's because most don't wanna learn how to adjust a carburetor or curve a distributor both things can be learned very easily.

Lol vacation put his kids through college

However, that one is more elaborate from the aftermarket I believe.

@@stevegiboney4493 looks stock to me.

@@Heartbeat1991 , it’s been a while since I’ve seen mine, I took it off because it was damaged from age .

It's exactly the same as is in my '76. It's stock.

not really it means the guy got restricted meaning and not alot of contact and from the size of the garage it focus probably on mass service. The service is probably good but he seems like the kind of guy who charge 1 hours even if its 15 min its the spot where you go do a oil change but dismantling an engine gonna cost you 3000$ XD. 80$ to make a diagram from your car with a carburetor its like 10 part max the only hidden thing in a car of those years is the fuse box maybe a hidden fuel pump LOL he talk like this engine gonna need 1000 spark plug pulled out in 15 minute. when you lack knowledge issue and trouble look like grand canyon.

Not strictly related to auto mechanics, but any craftsperson - if they're better off not making that money and instead suggest you to get better serviced by someone else or not even bothering doing something, you follow their advice. They're doing quite the opposite of trying to rip you off.

@@michaelsimoneau8364 so what? He's a professional, he doesn't keep his shop open by giving away his services. For some reason he has a full warehouse for his shop and is making profit, whereas many guys can hardly stay afloat, knowledge and expertise won't take you anywhere if you don't value your own work accordingly.

I give my honest opinion to clients/Potential clients and if I get the work great or if they are better off elsewhere I tell them that also. Treat them right and make them priority and focus on the money in a secondary fashion. $ is the byproduct of exceeding expectations.

My mechanic said he was very happy that I replaced the opti spark an my kid's 96 vette. Said he would rather never work on one again. Could do it but didn't like the job.

Interesting! Everyone vote this up so he sees it!!

@Zo Fryer ?

@Zo Fryer Why can't you service your own EFI fuel system? I've been doing this professionally since before EFI systems and I know both systems well and I'm here to tell you that plugging in a laptop and changing the AF ratio and timing is a lot easier, a lot faster, and a hell of a lot less messy than changing jets in a carburetor and using a timing light. EFI system's aren't any more difficult to learn than the old system's, especially the aftermarket stuff, you can download the software right off of the internet to work with any of them. And contrary to what I've heard hillbillies saying for 35+ year's now vehicle manufacturer's didn't spend hundreds of millions of dollars over the year's developing computer controlled EFI systems "just to keep people from working on their own vehicles", they did it because of ever increasing efficiency standards from the EPA, not to keep people from working on their own vehicles, anyone with an IQ low enough to think that is going to screw up anything they're working on whether it's a carb or EFI, and then of course it'll be everyone's fault but their's.

@Zo Fryer I thought we were talking about cars here, why is it every time the subject of performance modifications for cars or motorcycles is being talked about people want to bring up what John Deere does? These aftermarket systems are designed for the customer to easily tune the system, what in the world does John Deere have to do with it? And it's a bigger difference than 2 MPG with these system's, the narrative of "They don't make 'em like that anymore" only lasted until about the mid 80's when it come's to performance, you can buy a bone stock performance car nowadays that'll blow the doors off of any 60's muscle cars, it'll get twice the mileage, make twice the HP and hold a rock steady idle, the reality is that there's soccer mom's that are driving cross overs that'll beat any 60's performance car in the quarter mile, stop in 2/3rds the distance and out corner them, and the fact is they're like that because they were forced to improve everything needed for them to be that good because of government regulations, everyone's cussed the EPA over the year's but really the vehicles have become that more powerful because of the engineers being forced to make them more efficient, more efficiency=more power, it's actually been a blessing in disguise.

@@dukecraig2402 You are absolutely correct. I had a 71 GTO 400 heavily modified and it was a blast to drive but todays factory performance cars would blow it away, give you better gas mileage, smoother, quieter ride and have the AC on and all I would see would be tail lights. As much as I did enjoy those days they really don't make them like that anymore and be grateful for it. Well, that is until you suddenly see that loose wire/vacuum hose and have to find out where it supposed go. I like watching todays video's for Hellcats, Camero SS, Corvette's and they perform magic compared to the original muscle cars.

Carbs are easy to work on if you are not stupid

Some people think Horsepower rules all. I think it was Motor Trend a while back did a head to head comparison between a carb and FI, and the carb developed more power than the FI. They used the same engine on a engine dyno, just swapped out the fuel delivery system. For the extra few HP, for most drivers, hard to justify the headache of a carb. If you are running 1320's and every HP counts, then sure.

Well on the higher end of hps Carbs are better due to cooling of the Air as it mixx's with the fuel.

cheaper than figuring out the electronics. holley EFI system which would be the best way to go is pricey.

He probably didn't have the donor car 's wire harness, fuse box or ECU.

@@VC-Toronto I think I have seen that, they used a very simple EFI system like what was used on the original British Leyland Mini and the mexican made Beetles when they had to have a cat in Europe. Here it was known as a "digital carburator" to some.

All race series use fuel injection now.

Same with electronic ignition.

in those days the power built up and response to the throttle was slightly jerky....carburators were much smoother at building up torgue and power.

It wasn't long ago that "Real" mechanics would laugh at these kids that couldn't fix a car that they can't hook there computer up to.

Yes. They were mechanical back then. Hard to keep working correctly. In my HS autoshop, it was all carbs. One of my classmates had a Pontiac 389 with "tri-power" for those of you that remember that. What would this Corvette have had originally? A 350 with a Rochester Quadrajet?

Mrs Wizard has classic timing.

@@AZBEEMR bruh no omg

@Ride like a pro - Nah brotha; “the camera girl” (Mrs. Wizard) is super annoying. No no no.

depends upon who does the restomod work and how well he does it. All modifications should be documented and wiring diagramed. problems like the wrong AC condenser should be worked out. Using carbs instead of fuel injection is generally a bad idea unless you know how to fix it yourself. Also, all replaceable parts like the front transmission seal should be completed before final assembly. If this car had been done right it wouldn't have been in the shop in the first place

​@wesleysaams448 yea, how many do you know that get done right that don't come out of the same shop? This is the reality for most people.

Absolutely. In any industry.

...on that note, check out Peter Anderson - his documentation is _immaculate!_

Yah but old guys document receipts nobody cares that you replaced those parts. And you pay for everything you cant do sitting down so if your mechanic wants to draw up a diagram that could be useful

Exactly. I'm hanging onto all my invoices while I order parts for my 350 swap. It's a common swap but that doesnt mean I will remember every part I stuck in there.

@@nubreed13 not so important on swaps it either a good 350 or not most want to know how many,miles on the new drivetrain thats about it

Not only that, and it may look tacky, but labels on the looms wouldn't be a bad idea either

If you have a harness made ask for the print out, I rewired a few vehicles and I always used numbers on the cable and had sheets written out saying what was what just like in a book.

Painless Wiring is pretty well known for making harnesses with a full diagram. If you take pictures while you're installing it, it'll prevent a ton of headaches.

This. So much this. The effort early on in documenting and labeling will always pay off. I feel like I have learned that way too many times. Not just with restomods, but with projects in general.

I installed a factory tach in a car I had a while ago, which involved adding an extra wire to the cluster down to the firewall plug. For that one little mod I bothered to draw up a sheet of paper and stick it in the haynes manual I let go with the car...

I thought it meant experiments on wheels

If you spend more time troubleshooting than driving sounds like you have no idea what you are doing. An experienced person can fix almost any problem on a car in a few days.

I'm not paying for a few days.

@MoparDanthat was pretty clever! ...I was nearly certain this was going to be a generic "Cuz its uh Ford" joke. .l

@MoparDan Ngl i wasn't expecting that

buy a long block and ignition vs buying a whole car to scavenge the fuel and electronics

I've helped restore several old cars. Due to grandpa. He did this alllll the time. We did a full restoration to 3 ford fairlanes 55 and 54. The only thing we didnt keep stock was the drum brakes. We converted over to disc. One car was converted to 12 volts because the wiring harness was so degraded that it was easier for us to build a wiring harness than it was to repair or find. One. Lol that's why I like older cars.

I worked in the parts business for several years had this happen quite a bit. There's aftermarket companies that make straight bolt on components for suspension and brake upgrades but you're gonna have to pay for it but it's worth it in the end to stop dealing with the headaches

I worked in the parts business for a bit, and became the guy that knew his stuff, and was willing to work with the customer to find the right parts on oddball swaps. I guess now that's why I prefer to keep my car mostly stock or make it very obvious what parts are what.

Personal opinion. Is your opinion ever anything except personal?

Never seen a shop without a light and a scope...

I agree with this, as long as you do the job (or get the job done) right. Because the Wizard's right; it gets expensive really quick trying to figure out a hack job. That R12/R134 air conditioner system is a prime example. It would probably be cheaper to just replace the whole system with a R134 system than trying to troubleshoot the relays on a mixed system.

Among other things carburetors don't work well with Ethanol-infused fuel which is the only fuel available in my area. All the cars I ever owned that had them gave me problems at one time or another. I don't miss them at all.

It has an ignition box so no dwell, that would be points and condenser type stuff. The carb has to go though.

Any mechanic that cant work on a caburator isnt worth crap Thats basic stuff

That's a sneaky smart idea....I have a rear main seal leak that I might try this on.....lol ....lol....lol

Dude got totally hustled with that pad that soaks up the tranny leak! Hahaha. And the paint looks good right now, but just wait for the body seams to start cracking, what a POS!

Brakes are stock. Stock rotor, it's just drilled. Nothing special or difficult.

Those are not stock that looks like a dual piston big brake kit

Trent robey same, i have the most embarrassing oil stain on my driveway because of it lol. i need to know where to get a sticky foam pad like that

Most Chevrolet cars that came with the 305 and had their original engines swapped out wound up with the much more common 350.

Same thought. An ls is a much more reliable engine than the old 350 and 305$. But it's only that if u swap everything over.

Some people like the nostalgia of a car and the 73 doesn't look right without a Carb with the hood open. Most people buy old cars to "share them with others" rather than for actual performance. I could make my tank run at 10 mph but I choose 5 because that is what the originals did. It's for show not for go....

Because carburetors are easier to throw in and set up than turning a ls with fuel injection and a computer

@@derekderekison3241 An easy swap would be a 350 crate motor. An LS based engine does not have a distributor, so you still need a hybrid system with fully electronic and programmable ignition to make a carburetor work. I love carbs, but you would have to do so much work with this application to try to make it work well.

@@curtislovrak5390 you can put a 350 style distributor on a ls

The owner had a 165 hp 350 that was probably toast. The swapping shop decided on a junkyard truck motor and this is what you get.

I haven't kept up with aftermarket fuel injection lately. Hadn't heard about this unit. I checked it out. Wow! This thing looks amazing and brain dead simple. Will definately keep this in mind if I ever pick up a classic. Thanks!

That's exactly what I was thinking.

I agree easy to install and tunes itself. Fuel injection for the uninformed. Most mechanics could easily understand and diagnose it.

@@jerryhablitzel3333 put a Sniper system on my Chevelle. Couldn't be happier. Butter easy.

I have an Opel omega with this 3.0 engine, here in Brazil it was sold by Chevrolet, nice rev range engine, nice sound too

Very common swap here in the netherlands back in the 80's and 90's. Just like the later 2 liter 16v engine. Opel is great of these kind of swaps. I've seen that 3 liter motor in a kadett C.

Strangest Ive seen: A 2.3 litre carbureted 4 cylinder Ford in an old diesel Mercedes. This was also in the late 80s.

Did it the other way around, upgradet my Miata ND with 4 pots front. Car has stock 2.0 - 160 hp / 1050 kg. Have an old 1988 RX 7 also but that one is OK, has 4 pots front from factory ...

Too many moders think about going faster, but forget about stopping. Upgrade the engine - upgrade the brakes.

Exactly and the only other thing it would require is a low pressure electric fuel pump added to the system. Hopefully added close to the tank to pressurize the system so it has less chance of vapor lock and power it up with a three prong ($10 Chevy Vega) oil pressure switch to operate a relay when it gets oil pressure. EDIT: Everything he is saying is obviously very true in a lot of cases but this one is still in the basic simplistic car repair mode. The ones when someone does an old car and blends a donor car wiring harness w/factory fuel injection and body control modules controlling some accessories. And wiring nightmares, like splices and gooey electrical tape jobs with inaccessible relays, fuses, connectors and fuse boxes mounted on the other side of a metal wheel well against the fire wall.

I'm with you. This was a bit of a letdown to me. Tuning a carb for me if it's a 4150 means heading out to the strip or deserted country road with a timing light, vacuum gauge, box of jets/jet driver, spark plug socket/ratchet & a temp gun. With those few things I can make one run like it's injected & have a blast doing it. Who wouldn't wanna get paid to run a car fast up & down the road a few times??? I'm not sure what's involved with those Barry Grant Thermoquad copies but I guess they're much the same as a Carter/Edelbrock with metering rods & such. Not exotic but not in every corner speedshop either. Maybe that's what scared him off a little? The A/C problem? Nothing a simple trinary switch from Vintage Air or eBay wouldn't fix. If he does that "running off the compressor clutch wire" thing, that fan will have a much shorter life from running while on the freeway when it doesn't need to. I can deal with someone who truly doesn't know & I welcome the chance to share knowledge. But lazy? No thanks!

@@acemobile9806 Absolutely. That was not the car he should have used as an example. I sort of hope the owner sees this video and pulls his car out of that shop. Just maybe the guy is talkn this way for youtube but treats the owner right.

What a dick ! But anyone buying a car like this should know to put it up on the hoist and that pad is the first thing you are going to see.

That's always the problem with buying used... 9 times out of 10 (if not a full 10 out of 10), there's something that needs to be fixed, or it was worked on by someone who didn't know what they were doing. P.S- Recently bought an interceptor... They definitely put minimal effort in its maintenance, and they drove it hard.

Wise words. I would rather find a vehicle that’s completely stock knowing no one has altered it

Hondas are notoriously finicky with 8000 miles of vacuum lines.

Almost everything is hard to deal with on 90 Accords.

@Mike Anderson Volvos had a little LED with a button

It's depressing owning an old car and no one willing to work on it, much less have any knowledge on them even when it's just a 90s Honda or Mitsubishi. Totally on your own.

No lie, I was AC issues. They wouldn't look at the AC. It wasn't anything to do with anything that even needed an OBD2 port lol.

Not exotic, just outdated and uncommon enough that it's not worth a mechanic's time to know or care anything about them. Your average shop would see a fraction of a percent of their business being vehicles with carburetors. They aren't loosing money by turning those vehicles away.

Makes me feel old when younger guys are stumped and amazed by a distributor with points. What, no coil packs? How does this thing run?

Horse and carriage is even more exotic

Don't you mean "obsolete"?

As a carburetor guy myself, in the 80’s I was actually glad to see them disappear as emission devices were added, ending up with dozens of vacuum hoses. I was fortunate enough to have started on carbs in the late 60’s, but EFI in 1977. Other than CIS or mechanical injection, in 1976 model year, only two cars had true EFI, one injector per cylinder. The Cadillac Seville w/350 & the Datsun 280Z. Although it had injector #7 for cold enrichment by a simple thermo-time bi-metallic switch inside. It was stamped with max time & max temperature. The colder it was, the long it sprayed. A 3 or 4 gas sniffer in the tailpipe was normal. Anyone can put an “LS” in a car/truck. But not providing a detailed schematics, location and part numbers of non-factory parts is lowering himself to “Grease Monkey” status, doing the owner a dis-service and any future owner. The “Wizard” is right. I left a dealer of young capable Acura techs. On the way out the door one ask me how the fuel pump on his 2-stroke 6 cylinder bass boat engine worked. I told him to Google it! I paid my price, no tech school, just did it and learned. Mistakes live in your brain until you die. Doing it correctly & right using best practices is forgotten when they hand your paycheck!

Yes restomod's are bullshit. No one wants to buy a heavily modified vehicle. They aren't valuable in fact the Corvette is now worthless.

@@timothycc711 Restomods are fine for cars that are essentially destroyed to start with. It's when somebody chops up a functioning classic that I get nauseous. I've got a friend that did a restomod to what was actually a replica car to start with, would have been a classic in its own right, but... very few parts of the original were salvageable, the frame was paper thin rust in places, the engine was seized. It's essentially a new car except for the fiberglass body. It got a relatively recent Mustang engine with fuel injection, handbuilt frame, digital gauges, and it looks amazing now, you can't tell it's not original from the outside. The documentation is, of course, extensive. There are pictures and notes for the whole process.

Timothy Clark sorry man the old motors are cool but they suck. They don’t make a lot of power and they aren’t reliable at all compared to modern v8 engines.

There was a Gray 65 Mustang that was Restomoded it was like 250K worth of modifications I didnt like the red interior but the body was spot on so this car was on Jay Lennos garage a few years back so last year I seen it for sale from the guy from Michigan with all the cool old cars from the 60s /70s/80s etc so this same Mustang was for sale for 129K I was like wow I wonder what happened did it get smashed or just no one wanted to pay 250K for it

@@backyardboosters9128 lol what? You know those olders engines have continually been updated and actually hold up right? People even tune them and get lots of power out of them

This video is mostly bad advice and clickbait

so much easier and better to run a carb on a older vehicle

@@redblock5949 I wouldn't say better since if it was we wouldn't have fuel injection. Definitely easier but definitely not better.

Think of regular Corvette owners, now make then a hardcore boomer, that's the owner of this car, has a carb but also has cruise control

It's cost, really. The biggest, nastiest carburetors I know are like $1500, for a 1425 CFM 4 barrel, single carb. It (the one he has) looks like a Street Demon carburetor - They flow 625-750 CFM and only costs about $400, under $500 max. Fuel Injection starts at about $1000-2000 at least. They're also pretty simple. It's basically just fuel you need to have the Carb work. You just kind of plop it on there and go from there. Assuming you know how to tune it, or know someone who does. Carburetors aren't bad. They're cheap as hell and they can make good power - but don't get me wrong, fuel injection is definetly much better. But more expensive as well. Dude was probably just trying to save some cash. He'd need a different intake to make it work for EFI as well, which'd add more cost ontop of EFI being notably more expensive.

if your going to all the work why dont you just buy a celica?

I'm a contractor and can say those are the best fans for sure. Plus you get a sticker that says, Big ass fans. I always cut the S off fans so all my stickers say, Big ass fan 😁

@@assoonaspastablepizza8135 I have a brother who owns a huge truck repair shop. About 5 years ago he installed AC when he added a parts room. Increased productivity 50% in the summer. Actually paid for itself.

SPOT ON....I can relate to how you see things. Now a days...you open up the hood on these new cars and I just shake my head!! The car manufactures are making it so difficult , that they almost force you to buy into an extended warrantee. I like to keep it simple...where I am not forced with dealing with these STEALERSHIPS !! We old Gear Heads...stick together !!

@@williambirnbaum1501 a lot of unnecessary electronics like you said keep it simple stupid..

You should be ashamed of yourself i'm not even in my 30s yet and i could work on any kind of carburetor you name it motorcycle carb? already done that more fingers than i could count

That’s a great observation. Not that level of pain but my nitro RC car has to be tuned for hot, cold, humid or dry. So to me a fuel injection swap would be cheaper in the long run over constantly tuning the carburetor. Oh and just curious now you have it tuned for Denver does it run the same at the top of Pikes Peak?

@@duke9173 Probably not, you'd have to pull over and tune it by hand again just to get more air into the engine to climb Pike's Peak 🤣🤣🤣

air density is a pain in the kester

Imagine willingly driving a car with a carb.

Been there, done that. Plus, Denver is at about 5,000 feet, but the mountain roads to the west and north get as high as 12-14,000 ft. Carburetors are about useless in that kind of environment.

You can get more horsepower with a carb they also didnt want to play around with electric fuel pump

I doubt he running a mechanical fuel pump mate. Best thing to get rid of in my opinion. I've been stuck before run out of fuel put your Jerry's in but by the time she primed the battery gave up. In theory you're battery will be fine in the real world it may not. But an efi pumps a different ball game.

@@markgerman6446 maybe in ideal conditions but in practice most carb engines just suck pure hot air and never achieve the same power

Carburetors are great if you Know how to work them. I build a 6.0 with a healthy cam and a 750 double pumper. It made 527hp and went into a 71 Monte Carlo with a th400/2.73 gears. It cruises excellent , goes 15l per 100km and is An absolute beast when you put your door down. Wide band and carefull tuning is key if you want it to be right. It takes more effort than pushing buttons in a laptop. And before you answer me, because i Know it's coming, i do both carburetors and fuel injection , build and dyno tune everything i build.

Uh nascar uses carburetors

Love and hate...truer words haven't been spoken

That and usually carb cars wont have catalytic converters,when people delete cats from fuel injected cars they start smelling like that too.

@@Jdres123 or run them open loop and rely on the tune

DO IT. Just don't mix your A/C system with R12 and R134 parts.

Yeah, to me that would be enough to demand a refund with the threat of legal action. Sure, the buyer should have had a mechanic inspect it first, but there was intent to deceive. It makes the car worth several thousand less once you know it needs several thousand dollars worth of work. Also, it begs the question: what else is he hiding?

Restomod done right is good to go. Im doing restomod suspension and disc brakes from CBR for my 66 but also running a 360 and M21 4 speed

If the person doing the swap took the time and had a fair budget to work with i wouldnt hesitate to let any of my customers drive a swap. If it was an apparent hack job then you need to go through the issues and sort them out. Its just a machine it can be fixed...

They call that "two sixty" air conditioning.
