As a tow guy I'd like to thank you for continuing to keep these things driving.
Thought you had Ford to thank for that? 😂
@@ScottPC Ford, and, Hoovie!
🤣🤣🤣
@@ScottPC Ford? That's so 70s.
Says the guy who only has a sling 😁
Will 2023 be the year Hoovie buys a tow truck?
Will 2023 be the year Hoovie thinks of getting a pre purchase inspection?
I think Randy at Auto Auction Rebuilds has one for sale.
Will 2023 be the year Hoovie crashes and burns in an unsafe purchase hooptie all for the clicks.
If he did it would be a hooptie and his tow truck would need a tow truck.
That would be amazing! His own flat bed parked out back.
My first car I bought with help from my grandparents was a 69 Charger 383. The man I bought it from had a trailer hitch on it and used it to tow a fishing boat ! 😄 In 1978 It had 56,000 and I paid$ 1,500 for it . I thought I had the coolest car at my High School 😎 Nothing like the sound of a V8 with a four barrel. Those days are going away forever it seems 😪
Hoovie is learning the things everyone in the classic car hobby all ready knew. Most collector owners don't replace parts that degrade with time (like tires) "cause I've only put a 100 miles on it in 10 years" and most don't worry about making sure stuff actually works.
6 years ago, I bought my 70 Charger R/T site unseen, based on pics only. Flew into BC Canada, and drove it 3000 miles home to PA. Besides a ton a fuel, and the alternator crapping out (changed it in the parts store parking lot), I lucked out and it made it back just fine. Best road trip ever!
@K.M.V S it was down near Vancouver, so didn't have the mountains to worry about.
That's a car guy's dream adventure. Glad you could live it and thanks for sharing it.
Just got my dream car yesterday. 70 RT 440 375 hp, auto on column, No Ac. though. 34,000 mi. Florida car. 1 owner since 71` Plume Crazy purple, blk vi top, . I was going to drive it back from the storage facility in Pitt,Pa. The price I payed $11,300 included having it delivered to my place by car hauler. It should be here by Sat-Monday. Take care. From Sioux City,Ia.
To prevent the gas from boiling after you shutdown the the engine. Add a phenolic carb Spacer this is a Modern fuel adaption technique.
Was about to the say same, a carb spacer fixes this.
Open 1" spacer for more horsepower, if you have hood clearance.
The wonders of vapour lock . . .
It will stop boiling and prevent vapor lock when you driving. but can`t stop fuel evaporating when you park it with hot engine specially on summer times. best solution is using electric pump. Also with electric pump you should use original fuel filter with vapor return line.
@@houtanarefi3325 The car wizard has done a couple of electric fuel pump conversions on his channel for exactly this issue.
Tyler’s barely out of the car and the wizard “If you EVER sell this thing you HAVE to call me first”, love it. Beautiful car Tyler can’t wait to see the mini resto/what you do with her
Yup typical car guy we want to buy everything we see !
I really love this car! Keep it original I reckon. All the more important with the direction the world is going at the moment.
Things are about to move really fast now. Too fast for those asleep to realize it. They've been slowly working on One world Totalitarian control for centuries. And now it's here.
The things I love about you Hoovie is that you’re not a one car type person. Your love of automobiles is full spectrum from all avenues.
Insensitive joke about Hoovie being on the spectrum goes here!
Yeah he's an actual Car Guy hes into cool cars he's not a brand cunt
I’m the same kind of man I have live for all makes an models 🤌🏽 respect every build & the amount of work put in
Except hardly any love for Asian stuff, not counting his wife!
He highly favors Mercedes, BMW, Ferrari, and other Euro brands. He'll toss in some American cars, but you never see him with any kind of Japanese cars old or new.
Def *NOT* scammed. Needs a few things sure, but overall it's a pretty honest original car (except the axle ratio). Well done with this one!!
I love hoovie but when he said low 300’s for the axle ratio I cringed
@@saratc660 Yeah, would have been high 300's from factory and this sounds like 4:10, which is what have in a 489 case on my sur grip 8 3/4 rear end.
I agree. I missed the perceived scam part.
Have to say I shake my head when anyone buys any car, but especially an older one and heads out on the highway without having a basic safety check done. If you don’t value your own safety, consider the others sharing the road.
That said, maybe it’s all just click-bait and clever editing. Tyler is smarter than his on screen persona.
@@ppeterson9359 Yeah surely he wouldn't REALLY have gone on the highway on 30 year old tyres? If he did, he risked not just his own life but that of others around him - I've only ever had one blowout at highway speeds and I just barely managed to control the car - fortunately no other vehicles were close by or it could have been very different.
Disappointing thumbnail to be sure. This looks to be an honest car that had been sitting for a lot of years. Things like hoses, tires, leaks, etc are to be expected when buying a car from the 60s
Any coronet or charger....base model or any model....a gold mine. Worthy of respect and resurrection
For the gas boiling Edelbrock does have an extra thick carb gasket that insulates some of the engine heat. It did the trick on my old small block at least.
The "RB" big blocks are different but IIRC Mopar and the aftermarket sold some kind of a block off plates or gasket that helped with that issue. Also a good fuel pump properly placed. Good ol Holley to the rescue..
That melted wiring on the firewall is from the bulkhead connector going into the cabin. Mopars are famous for fires and melted wires in that connector area. I had the same issue with my 74 Dart
Yep and from the connectors to the voltage gauge. Always by pass the voltage gauge on an older mopar
Usually the 10 AWG ammeter wiring running through that connector. Bad design. The fix was to either swap to a voltmeter or run that heavy gauge wire through the firewall by itself.
I jump the ammeter on all of my B body Mopar
I watched a 1976 Duster burn there in 1985… complete meltdown of harness… my buddy and I re-wired the whole car… it wasn’t perfect but the car ran for years after that!
Lol, I had same problem on my 74 Plymouth Scamp (same car, really)
What I love about Hoovie is that he never learns from his mistakes.
Cars with issues == good contnet.
He learned how to video and make money off of them. That's why he keeps making "mistakes"
There's a reason they called these old cars "More Parts" ;) at the time. Nothing is super expensive, but something is always coming apart or needs work. Bad to own, but GREAT for channel content I guess?
@@dootu You're mistaken, you mistake his mistakes for mistakes.
Exactly and continues to drive without a breather or a rag or literally ANYTHING to keep dirt and debris from entering the motor while driving 😂😂 smh lol
I'm a tree hugger, but I L-O-V-E old Detroit muscle. Just the rumble of that 440...ear candy for this old man.
The rumble of these old chargers always makes my tummy dance and my brain spark like a firework ... no other car does this to me 🤩
For me, this is the best buy yet, mainly for the originality and nostalgia factor. A close friend had a few 68’s over the years and we spent many hours cruising. All were big blocks and a lot of fun.
Damn! The Wizard sure looks like a boss when he drives the Charger
Yeah Boss hog🤣🤣
I recently visited the USA and i can see the passion for cars, we had our V8s taken away years ago in Australia, unaffordable to most people just drive 4 cylinders but i could see they are still very much prevalent in the USA, i really hope this never changes but i think our days are numbered as car guys, the boring days are coming!
I just hope they keep making gas!
Tell the EPA they’ve over stepped their boundaries!
I thought Holden made 6 litre ls V8s what the hell happened down there first your guns then V8s what tyranny what are the MFP supposed to drive when pursuing the "Toe Cutter and his m c gang
Turbo super charged V6 pushing 300-600 horsepower on street and pump gas
1968 penultimate year for muscle cars from all the big 3 and even AMC. Awesome car Tyler. I’ve been enjoying your TV show for about a year now and look forward to digging into your CZcams channel. Living vicariously through you and Wizard lol. Keep up the good work!
Hoovie, our families 68 Charger R/T 440/727 has a gear vendor overdrive for the Torqueflite trans that helps the rpm come down at highway speed, I would look into it but they can be expensive but that could help solve your problem. Glad to see you enjoying your Charger as our family does with our own
For a performance built that is THE solution! Otherwise you are back to stock gear ratio -which is great if you are going for a restoration build vs. performance.
Problem is, your differential gets hot as hell on the highway with low gear ratios. (Mine was a ‘68 GTX 😊)
Or swap in the proper rear gearing.
There's a misconception regarding drum brakes. Properly functioning drum brakes work just fine. Disc brakes are superior, but only when it comes to brake fade under hard driving and if they get wet. The main difference with modern braking systems is anti-lock brakes, which doesn't come with a conversion.
Drum brakes actually brake better than the equivalent disks, but as you stated the big drawback of drums is brake fade. However unless you're tracking the car or going downhill daredevil there's nothing wrong with drum brakes.... Except working on them, god do I hate drum brakes!
@@richrishel9809 Yep! Indeed!
My only complaint with drums are manual 4 wheel drums, at least Chrysler. I switched mine to power drums. Looks like this is power drums too.
@Rich Rishel my daily has drums in the rear, but it is 27 years old…
And to that end, adding some discs in the front of a car like Tyler’s I think would be welcome change territory, if not all around.
Just finished restoring a 68 Charger Bullitt tribute. Lots of time, effort and $$$, but worth it when done. All the best with yours!!
The thing I love about Hoovie videos is he makes me never want to buy a vintage muscle car.
Ammeters were full flow (no shunt), usually took out the entire dash loom if not the whole car.
Old Dodge front end, may as well rebuild the entire thing. Only takes a couple hours. Moog parts typically last forever (or at least used to, these days who knows...) The best part about them was the tie rod sleeves almost never seized up. Pay attention to the rear of the K-member where the LCA passes through. Usually it was the smaller Darts, etc. that cracked there but some of the larger ones as well. Replaced a ton of them. LCA bushings took a beating as there's only one per side.
Drums on those worked ok but not as well as discs. Drums will stop you quickly - once. After that they fade rapidly.
Check pinion snubber, especially if there's wheel hop under hard accel. A little bit longer helps immensely with those twenty foot long leaf springs.
Those big blocks were scorchers. Have to let them cool off for 4 hours or so to keep from being scarred for life when changing plugs. Blocking off exhaust crossover helps keep from fuel boiling off. Hard hot re-start always with big block Chryslers. Anything to help them remove underhood heat helps.
V2 compressor always was a monster but as solid as they come. My vote = keep it if it works, they're epynomous.
Take a good look at the water pump. Easy to change and prone to leaks on some.
Great response, all true, my '68 charger back in the day had brake issues as well will pedal going to the floor one evening, and the electrical junction box on the firewall melted as well and mine was the same dark green as Hoovies, with a 318 that ran great!! miss the fuel filler on the fender instead of under the license plate that most cars of this era had.
Sounds like you have significant experience with these, thanks for chiming in!
14:25 Wizard knows his stuff! Back in the day the first thing you did when you got a muscle car was tighten up the play adjuster....They came "loose" from the factory to help the box last longer and make it easier to steer. Tighten them up and you improve the handling immensely.
This is by far my favorite car in Hoovie's fleet.
Probably time to scrub the blue protective coating off of the tires. The problem with your lights is likely the vaccum cannister has a corroded opening in the bottom of it OR you have a broken vacuum arm on your headlight switch. As far as the ac switch not working you can still find the nos plastic switchboxes inside the trimplate. Theres many so look for same part number as you take out. On the wiring, its an inherant problem in the spade connectors. You take the plugs out, use elec cleaner and a brass brush to clean both sides and then put a small amount of dialectric grease in each female side of the connection. Just a little and dont let it cross over to other female plug ends. That should solve the resistance heat issue. Yoy can also run a heavy guage shunt wire from the alt stud to the start relay stud. This sends all the heavy current right back to the battery and takes the load off the inside of the car. Note. If you do a shunt your alt guage will be inaccurate. You can plug a digital into the cig lighter to check periodically for proper output. Myself, 37 yrs in mopars, primarily chargers and other b bodies. Ive seen it all.
Awesome! I would like to visit with you in the future once I get my Car delivered. Will need advice on any upgrade repair, etc. Should be here by Sat. It has no AC. Can I upgrade it to AC? Take care. From Sioux City,Ia.
Double thick carb gaskets (not metal spacers) really helped keep my intake on my 318 from boiling gas (video of the experiement on my channel). You can also run a return line to the tank with a filter that has a choked orifice to let vapor get sent to the cool tank.
Been doing the same successfully for about 25 years.
Double thick gaskets are OK but risk leaks and breaking the carb baseplate. The answer is a phenolic spacer, it's fancy space plastic, the stuff used on space capsule heat shields. A few common outfits make spacers out of it.
It's also a much bigger problem with those Edelbrock/AFB carbs. They're all one aluminum body so they transfer heat. The base plate of a Holley is magnesium, then there's a gasket between the base plate and body, another to the metering block, and another to the fuel bowl. So in a Holley the heat must pass magnesium and 3 gaskets instead of just one chunk of aluminum with the Edelbrock.
@@snek9353 my uncle had a wood set on a Oldsmobile, I didn't ask how long it took to make all of that. He used left over stuff he didn't use on the house repairs.
@@kennethwallace4338 Yeah wood is an option, don't know if they're still made but used to be able to buy spacers made out of wood.
I've also used wood often to make custom adapters, to make a carb fit in some combination, and/or have smooth exact transitions.
Opposite problem in Canada lol. You want the carb almost inside the intake because of our winters 🤣
Only hoovie would say give it the beans with soft brakes 😂
Nah, there's no shortage of dumbasses in vehicles.
Fav CZcamsr of all time
Excellent talking points, Tyler!
Put a Gear Vendors overdrive unit in after the transmission. They are user friendly.
As long as nothing is molested.
They are original only once
Put the right 3.23 gear in the rear end. Unless you are drag racing, steep gears aren't needed.
@@Welcometofacsistube I think they are bolt on and fully reversible. Besides if you have a driver that you want a little pep these are almost a requirement.
@@hotpuppy1 May lug the engine with the cam change. 3.55 is good for acceleration and light cruising (55-60 mph).
Came here to say this. Not a permanent modification and you get the best of both worlds. This is what I would do.
Wow, so nice how it's basically all original like that. What a rare find. Hate how normally they are completely hacked up. You definitely did well on that one!
My father bought his red 68’ charger 383 magnum brand new in 68’.
We towed our StarCraft pop-up camper with it for several years, it was one of the most bad ass tow vehicles in town, I still have a pic of him proudly standing in front of it with the camper next to it in the driveway.
I love how Wizard's eyes shine sincerely for not having to mess around other "mechanics" F words in the car.
You can put a phenolic spacer between carb and intake to help with the gas boiling
Thankfully Wizard mentioned just doing a repair and refresh on the drums. For what use this will see they're more than good enough. If it saw enough drive I'd worry about a 4 speed/overdrive before disc conversion.
There is a 90's show I watched as a kid called Due South, your interior reminds me of the Buick Riveira? in the show. So very green!
Most of the Mopars I had and worked on had 323 gears in the rear from the factory. Love them.
Great stuff. I always enjoy the friendship you two have, and I get to learn something along the way. Great car, good luck!
B hi
Nice car. Typical with many that I've owned as well that they are not fully sorted out or sit long enough to develop leaks. That one is a good find and will be a great project.
Hoovy, l live in Tasmania and we have never met, but, it's just like you're the guy who lives next door.
You are an absolutex 'natural' and watching your videos you put a big smile on my face.
We have much in common. 😆
That color is AWESOME!
I love the wizard test drive section, hope we see it more often in the future!
13:42 That doesn't look like stacked tolerances on the LF wheel to me, it looks like wheel bearings.
Or loose lug nuts
Probably my favorite styling in a Dodge muscle car. Love the round tail lights. I'll take one in plum crazy purple.
Wizard making the 440 bawl...priceless.
1968 Dodge Charger RT 440 Best Mopar of all time even when its all factory original aside from a past repaint and some brakes & headlight work still looks mostly original OEM spec thats good to see and know of from past history its a very iconic American Muscle Car.
THIS IS ONE CAR YOU MUST KEEP!!!!
Do not change much on it but if you do,box up the parts you take off and keep em. By the way,sounds like 3.91 rear gears.
3:50 LOL.. I just figured out who you sound like.. Jeff Goldblum. You have him down perfect.. the same pauses, inflections, everything. Very entertaining!
Your love of automobiles is full spectrum from all avenues.
You should look into a Gear Vendors overdrive unit. Its a separate overdrive that will drop highway rpm significantly, turns 4.10s into 3.08s (roughly), plus you keep the snap off the line. Totally reversible too. If you want you can even split shift it, giving you 6 closely spaced ratios. Also a Phenolic spacer will help with the fuel boiling, making hot starts easier.
your just paying for a overpriced unit. Just swap a A518 if you want overdrive and call it a day.
I agree I put a gear vendors on a motorhome with a three-speed boy went a difference
I noticed you try to comment to hoovie,but sadly he don't care about his viewers.
That's what I did. Problem solved!
Its so cool to see you branch out from just testing tow rigs, to messin woth muscle cars
Yes so glad he got rid of that lightning lol
I want to see the towing test for the charger
I had a 1969 Plymouth Roadrunner 440 and it was a beast. Especially after I did cam and head work, headers and all that and using all MOPAR high performance parts. But this is back when you could pick up a nice one for 7 grand or less. I can only imagine what they are asking now and not to mention the risk of VIN swapping etc..
So what year were they still going for $7k?
Bad brakes & loose steering.
Tyler: "Give it the beans."
When you buy the cheapest version of the car you want on the internet its usually not in perfect condition, it just makes sense. It's still an amazing car and would be proud to own it.
Wizard making razzberry sounds as he's poking around underneath is the best thing ever!
In 1971 I bought a 69 with a 383 that was baby blue with a white vinyl top and white interior. Beautiful car. I'd love to drive one now just to see what it feels like.
Fix it, drive it, love it. I love it...I'm grateful for the video, and that wonderful Charger 😊.
Thank you for keeping this car original!
So if the car has a fake plastic steering wheel ( as you stated), does that make it real wood? 😁
Haha, good one
Good comment. I was wondering what "fake plastic" was when he said it.
My Dart has the exact same wheel and manual fast ratio 16 to 1 steering. They never were real wood but looked nice when they aren't all worn down and cracked like mine.
@@69Dartman Your OEM wood (plastic) wheel can be restored to look like new.
Wizard fits so well with that car. He looks right at home.
Great project, thanks for the video
Nice ride! Be sweet after you fix all the little things. Car is really clean! Nice find!
What a nice old car! I love it. Congrats! You'll get all that little stuff squared away and have years of enjoyment.
Very nicely put together video and very entertaining as well. Thanks for posting this.
Bot
Hoovie don't you ever give up, this reminds of the Jaguar👏👏👏👏👏👏👏💯💯👍👍
I knew a guy with '68. He swapped the cam out and it didn't produce enough vacuum to open the headlamp doors, like Hoovie's ex-Sbird he had to put a small compressor under the hood.
I think I watch these more or less not because of Tyler’s humor, but to watch the wizard teach me things about cool cars
Who cares about the troubles? It's a '68 Charger R/T!!! EPIC adventure. I wish I'd never sold my '70. I'm jealous that you scored a '68 that's so nice.
Even with a 4.56 it would be doing 55 at 3000. Make sure it’s actually shifting to 3rd and if so check the tach for accuracy. Something isn’t adding up. A healthy 440 with that steep a gear would boil those tires at any throttle level
Very nice car, and I think you did good with this one. I'm excited to see if all repaired and back on the road again. In my mind this is a keeper.
You guys always make me smile..lol
Skilled, knowledgeable, experienced car guys pay a fair price for solid cars worthy to restore, then you have Hoovie, a guy with more money than sense.
Hey Hoovie, take the Wizard to shop with you.😆
The rear end has gearing set up for drag racing which is why it’s so quick off the line and why it’s so high when you go interstate speeds.
A suggestion to you and the Wizard for the carb / gas boiling.
On mine (6-pack) we used a couple of thin spacers with gaskets between to insulate and raise the carburetor off the hot engine / intake.
Awesome purchase! Love the dark green.
I Love green!! I also own a 68 Charger RT and these are comfortable cars and handle pretty good,usually the steering box fails after years of mileage and age...Drums do work pretty good,try to fix them before converting to front discs..
Those axles can actually blow gear oil out of the vent because of the location of the vent at the "T" for the brake line. It could also possibly be that. I have basically an identical axle swapped into my 1970 Duster and it did this. The aftermarket vents for whatever reason must be different than the originals and its likely you have one like I did. Because my car is not original I just went for a bolt for a newer truck and put a vent hose on it and that has solved it. I can tell you for sure it doesn't have a 3.23 rearend because it would be somewhere around 2800-3000 rpm at 70 mph with no OD and that size tire.
Just bought a new R/T Challenger with a six speed. Nothing like the sound of that Hemi while you row your own gears!
that entire car is my dream car.. my fav year and color combo
Mine too❤❤❤ Dreamcar
Awesome color combination! Love that shade of green and the white stripes and top. 👍😀👍
Tyler your video just what I needed. Even if you have to put money into it's still one on the coolest cars you ever bought! The only cooler would be the the General Lee!!!
Hoovie VS the Wizard. They both win. As always I am entertained.
6 pack and AC were mutually exclusive... The front carb and the AC compressor share the same space.
That is a stock Mopar OEM R2 compressor. Damned good piece.
Nice project car!! Looks like easy fixes since someone didn't try backyard repairs on the car.
Make sure the transmission is shifting into high gear. I've seen the kick down linkage on those out of adjustment and they stick in 2nd.
Yup, wouldn't surprise me if it wasn't even connected.
Hey! Congrats on making it into this article,

See What Makes This Survivor 1968 Dodge Charger R/T 440 So Dangerous To Drive
Story by Aislinn O'Shea • 4h ago
I was surprised to see this on my internet feed!! Love the video!!!
Can wait to see this project
The brittle wires are probably going to the amp meter on the dash. Your best bet is to tie the two sides together on that gauge and do without it. Its a fire hazard. You can replace the gauge too with a volt meter.
You are absolutely right. I came here to say this. When I buy any pre 70s mopar, the first thing is to change the ammeter to a volt meter and upgrade to a two wire voltage regulator/dual field alternator.
Love that car! Great color too
Beautiful car, Hoovie. Verify the rear axle ratio by counting the number of driveshaft revolutions needed for one wheel revolution. Both wheels should rotate in the same direction since it's a Sure Grip. I had a 68 R/T back in my younger days with a 3.23. 3000 RPM @ 80 MPH. The transmission may not be shifting into high either due to someone installing a manual reverse valve body, aka brainless (D=1 and 1=H), or there's a problem with the transmission. Make sure the linkage between the carburetor and transmission is functional and properly adjusted. That linkage "tells" the valve body how far your foot is into the throttle. The governor "tells" the valve body the output shaft RPM. That's how the original valve body "tells" the transmission when to shift. BTW, right front wheel bearings are loose or worn out. Normal those bearings are good for well over 100K if they are repacked at every brake job.
As Wizard said he is able to tune up what you have depending on what is all been done for the drive train and suspension.
I have no interest in ever owning an old muscle car, but do appreciate hearing one burble by on the road, fully sorted. I'm looking forward to this. It sounds like a fun project car.
They didn't handle worth a damn, brakes faded after just a couple hard stops , drank fuel but when you are rolling and plant your foot there is nothing else to compare
The good part is you can get anything you could imagine to make them handle and comfortable. I’ve got a chevelle with an LS and a 6 speed in it that once they are sorted are very reliable
Yeah, pretty to look at. that's about it. I'll take my modern Hemi Charger with AWD that handles like its on rails.
It was really common for the main power feed through the bulkhead connector to get hot & melty like that. The problem was in the blades of the connector itself. I would usually just solider in a new piece of wire on either side of the connector and run it straight through. Might take a little drill bit work.
Another common problem was poor connections at the back of the ammeter. It'd get hot and kill the meter as well as melt the wires. Worth checking that too. Nice car! Cheers.
I do like the green, especially the interior, wish they'd offer that again and other colors on new vehicles.
My dream car right there!! ‘68 RT 440/Hemi 4-speed, manual tho, of course. Yours looks beautiful the way it is. I’d keep it mostly original as well, but would paint it black or a B5 blue with a black vinyl top and a champagne interior. Damn, my eyes get watery just imagining it! Great vid, btw!!
Nah, gotta leave this one green with that white top and stripe.
3:28 are we really going to get on board with electr 🛑✋🏻
No.
Cool car. Gearing is easy to figure out. just mark the tire and the drive line and rotate the driveline and count rotations until the tire makes a complete rev. Would have been interesting to see in the video what it was
That's what needs to be done. I don't think the transmission is shifting into high. I had a 68 R/T with a 3.23. 3000 RPM @ 80 MPH. The trans could have a reverse manual valve body. That's a beautiful car.
or maybe the tag is still on it but a 440 with a/c and at should be 3.23's or 3.55 at the most
With an open differential you mark the driveshaft, jack up one wheel and rotate it *two* full revolutions. Count how many turns and fractions the driveshaft turns. The ratio is that much to one.
