@Rodolfo Benza I think they said the old motor that they pulled out of the duster was not the original motor, but a drop in motor from around 1975.. Wonder if the owner still had the original, in that case it would have been cool if they used that for the rebuild.. Cheers!
Great refresh on that old Duster but I don't think I would have changed the gear ratio in the rear end if they weren't going to put in an O/D. Wonder what it would take to get 200 hp out of that engine, how radical of a cam you would need. Nothing to lower the mileage, though. I would like to build one with better power but also try to build for mileage, like 30 mpg HWY.
Back then we did not realize the cars of the future would have cheap aluminum engines with fancy computers that could shut your car down with a glitch. We also did not realize how expensive these cars would be to maintain as well. Tweaking a carb is a lot less expensive than replacing a computer chip. Local garage found slant 6 with very low miles, replaced the original seals with viton seals and replaced the carb with fuel inj. with today's oils, this engine should easily pass a million miles, barring accidents.

i caught that too. We know brake fluid mixes well with condensation, I'm betting the inside of those lines were rusted as well as the outside. To be fair, there must have been a budget.
Pause at 8:15 and frame forward using the period key until the top wrench is removed. You can see that the bare brake line is shiny enough to reflect light and no rust is detectable. Looks almost new to me. The coil guard that protects the bare brake line tube looks cruddy from the spray undercoating and road dirt. Where is there a line rusted half way through? People will die?
Legend has it the slant six was made from tank armor , cannon balls and a turd from a bald eagle that rode on Washington's shoulder as he crossed the Delaware
I want to thank you guys for a great video! And a great trip down memory lane! My sister had a 1967 Plymouth Belvedere slant six 225. It was smoking and using oil! With about 125,000 miles on it. My senior year of High school, I graduated in 75, The auto shop teacher, let me pull it, tear it down and rebuild it! Ran like a champ! She just had to pay for the parts. She put around 60,000 more miles on it, the car wore out, and we ended up putting that engine into two more cars before it was sold to some one to put it into another Chrysler, still running like a champ! I didnt do it as well as you guys did but I really enjoyed the video!
I had a Duster with a slant six 225 and a 4-speed manual trans when I was a kid. That engine was indestructible and very dependable. I loved it. I wish I still had it today.

I am happy to see 6straight six and slant six engines being brought back. Some don't realize these engines have a ton of potential. I love it when they are upgraded with EFI headers and a turbocharger
Got chills and a tear in my eye when I heard the engine turn over and start. 1971 Red Dodge Demon with the slant 6 was my very first car. That engine was a tank. And yes, it rusted a lot around above the wheels. Later got a 1974 Maroon Dodge Sport with the 318 V8. You never forget your first love.
I still have my first car, Light Gold 1973 Dart Sport. I destroyed three 225s before I put in a 360. The car is sitting in my garage waiting for my kids to move out so I have time and money again.
I had a green Demon 318 wish I had it back. Still have a '68 Dodge PU slant six I'm gonna drag out after seeing this. At 66yr I figure I better stop putting things off.. Time flys at my age..
I bought a 1967 Dodge Dart with a 225 slant six when I got out of the Navy in 1975, I truly wish that I had that car again, nothing stopped it, boy those were the days, thank guys, you brought back some good memories for me.
My first car was my father's 1973 Dodge Dart with a 318. It was fast in a straight line but the brakes were scary and the suspension was spooky soft. I'm surprised that I survived high school in that car.
@@epistte right, my dad had a new '64 Dodge truck with a 318; it was a perfect engine for a truck, lots of torque. My 55 ford ranch wagon (hand me down) with a 272 v8 (Y block) was a good car at the time too, Maybe it made 132 hp like this slant 6!! ;D
@jigga jaw Remember, It was the same engine used in the 55 T-bird so may be a little more. 32 hp would be what a Corvette had with its little six, when first introduced in 1953-4! ;D LOL.
@@ronschlorff7089 that "blue-flame-6 " weighed 40lbs More than the 265cu in V-8 in '55, 150Hp vs 195. I WONDER why GM didn't cast several-thousand 235L-6s in alloy!?! That would've dropped 80-100lbs, and would have made the C-1 a "More desirable" car, rather than the Rich-man's curiousity it is now. You Know if they'd done that, ALL of those alloy 235s'd be LONG gone.
I have been a professional transmission rebuilder for 40 years. I have built 100s of the 904/TF6/999 transmissions. they are one of the best ever made! only topped by the big brother, the TF8/727,,,,,,,,,,,,,,
My brother and I rebuilt a 727 for my 66 300! he was a tranny guy and knew how to stuff an extra clutch or 2 in many trannies, and which holes to drill in the V-body plate to get a better shift! Oh for the simplicity of the 60's engines! Very unusual car, 4dr pillarless with bucket seats, and a police interceptor 383, carter AFB, That thing would scream! Wish I still had it!
@Old Skool I picked up a Torqueflight many, many years ago, which had a adapter to mount it on a small block Chev. The adapter was heavy as hell, adding a nice heavy flywheel, for more torque, to the SBC, it was bullet proof. It also had a B&M add-on where I could pull a knob, and adjust the, the... (old age kicking in).. I want to say they don't have a valve body, but I can't recall what they do have. I just remember I could pull the knob all the way out, and it would rev higher before shifting and shift harder... This was long enough ago, TH400 were still on the drawing boards! LOL
I'm glad I was not the only one thinking that. I was sitting there the whole time saying what's the point of doing all that work if they're not going to paint the engine bay. At least paint it black or something to make it look good.
Some perspective: That's less HP than a modern 2.0 Subaru flat 4 and only a bit more torque. A Crosstrek could take on this beast in the straightaway and utterly lose it in the twists ... but it wouldn't sound as cool.
GREAT video for me. I was trying to save the Slant 6 back around 71. I worked in the engine lab at Chrysler. I really pushed a 170 cu in turbocharged package with a flow through head. Great memories. Big block replacement research was interesting too. I'll just say my Honorable discharge got me the best job ever.
Old Mopar guy here. Great job on building the engine and refreshing up the Duster. I would tell you missed out on one part of the engine build, that is rotating the carb 90 degrees and having a plenum welded in the intake manifold so balances the gas/air mixture to the engine. The way it's set up now - the primaries feed the front cylinders and the secondaries feed the back cylinders . Makes a big difference!
Where would you add the plenum--how large would it be? Could you separate a Holly projector-system, so you'd tap & drill 4 spots along the 6-armed intake-piece/manifold, then you'd have "port" injection?
Ford guy too, but, when I was a kid, my uncle had a black 64 Polara, 383, Torqueflite; the old "cripes-lers" (as we car kids called them) were nice! New ones you can keep, or give to me to sell and get more old Fords and Mercs;......got 64 Ranchero, 64 Caliente, 67 Cyclone now! Looking for a white '64 Fairlane now, to "tribute-ize" as a T-Bolt!! :D
OMG I loved this! I had a dodge Aspen for years and couldn't kill it . It had a bad fuel line, a seized tranny , broken front pax torsion link and the drive shaft fall out. All easily and economically fixed. That thing ran like hell . Thanks for the memories.
I had a Dodge Aspen also. 1977 model 2 door, 225 slant six and four speed overdrive on the floor. It use to get 27 mpg at 60 mph. Plenty of power with the manual transmission but no airconditioning on that car. Transmission got noisy in fourth gear. Today you would take it to a transmission shop. Only 12k warranty in those days and I had just over that, maybe 15k miles. So I pulled the transmission myself, replaced the bad bearings and reinstalled it. Perfect! Those were the days when you could fix a car yourself with mostly simple tools and some common sense. I didn't even have shop manual for the car. Wish I had it back today!
I bought a 1978 Dodge Aspen Custom Sedan with the 225 Super Six and A904 automatic 3-speed transmission with only 77,400 original miles on it May 14, 2021 it sat parked for 20 years and it's taken me a year to get it running again and I have put 66 miles on it . Still has a slight engine misfire likely due to the cheap Carquest plug wires and Autolite plugs the owner's manual calls for Champion spark plugs and the engine stalls if shifted from Park to Reverse but if you shift from Park to Drive then shift to Reverse the engine stays running and the car moves but the engine sounds like it wants to stall unless you feather the gas when reversing.
Really enjoyed this rebuild. Brings back a lot of memories wrenching on the old slant 6’s I’ve owned. Such an easy engine to work on and such a workhorse on top of it. Great job guys.
@MDS points aren’t too bad to change, but yes depending on the car it’s in, getting to the distributor was a pain in the rump that’s for sure. Slant 6 always had a vapor lock issue that was pretty common and annoying too 🤣
America has always had this incredible skill of being able to design and build an enormous engine that outputs a ridiculously tiny amount of power. This skill is virtually unique to the states. Impressive.
Their figures are rear wheel wheel horsepower don't forget. And if you compare it to some eurocar, make sure you compare it to a coupe variant of a plain everyday family car of the same era. Oh, and while you're choosing a car to compare, get the smallest engine option like this one has.
I’m honestly impressed. It’s not often that you see mainstream Kroger brand hot rod TV shows build a car with something other than a Great Value Chevy 350.
The rebuild of the Slant 6 was fun to watch. Thanks for sharing! Back in 1980, we bought a 1976 Plymouth Valarie stationwagon with a slant 6 in it. After getting out of the service and going back to SoCal, I decided it needed a little more getup and go. I found a 4 Blb manifold and a small 4blb carb to install on it. After I got it all set up and running, I took it for a few test runs and figured it just didn't do much for it. So I removed the carb and manifold and put the stock back in. I then traded it in on a 1979 Dodge Aspen stationwagon with a 318. It had a bit more power! :)
The mighty slant 6. In Australia I had 3 Valiants with this engine. The Dodge Valiant "S-series" , the VF And VG models. My all time favourite donk. Thanks guys. Very nostalgic
I owned two Darts. My first was a 1972 pale yellow, and my second was a light blue 318 for 1974. I loved the shape of the Dart and wished I had never sold it.
Being a commuter and driving more than 100 miles or more almost every day my Valiant with the slant 6 was my go to vehicle. I did not know then there were different HP ratings . I wish I had one of your motor rebuilds like this super super 6 you built for my commuting drive time. I guess it is never too late to learn. Thanks for the great tutorial videos.
Yeah, old inline sixes are nice when at their peak. I have a 200 in my 64 Ranchero, freshly rebuilt to spec. Runs like a champ, and with one Flowmaster, sounds pretty darn good too!!
That little car will handle better, drive better and set you back in the seat better than it was new. Nice job guys. Thanks for sharing the video post and best of luck 🍀👍🏼🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
@@tracyborn3517 Word, while you're in there, have removed the entire engine and are under the car, you might as well do some cleaning, if not just for aesthetic reason, but for reduced risk of failure too.
No, it's not Just you. It always creeps me out to see these shows like "Wheeler Dealers" (the absolute worst) bolt on new parts to a grungy greasy car!! Of course with "Road Kill", that's their "trademark"! Pressure washing ain't that hard,!! Hey, just get your "worthless son" to do it, ...and off his fricking phone!! Ha!! :D
These guys or who ever makes clips like these are very educational to people like us. I never knew about the weighing of the pistons thing I have seen quite a few clips on engine building but now that I know I will use it.good job 👍🏻👍🏻
Wish I still had one of my Dodge darts. 1967,68 with the 225 slat six put a header and intake on it and it was fast for a six,69, and 1971 with the slant six. love these cars and this video brings back some great memories. Thanks for sharing.
All nit picking aside, this was a good lesson in rebuilding a classic. I'm doing an 85 LTD, fun retirement project, so guys like these always give me good ideas.
You Guys make me wish I Still had my 1973 Plymouth Gold Duster!!! It was equipped with a 225 Slant 6cyl with A/C ,a 904 trans , console shift, bucket seats, and a flip down rear seat. The paint was Red with a white vinyl roof, and white side stripes with the words Gold Duster in Gold Letters Below it.
That's the nicest thing I've seen anyone do.. especially for someone else..and so full of nostalgia and so amazing to watch..and the effort and professional application just so progressive in the final development.. kewl dudes..?
@@chopchop7938 lol its like only changing the right front brake pads and not the left front then wondering why the new pads wore out so fast or why the car pulls to the right when the brakes are applied lmao
I enjoyed this Video. The Information was very Valuable. and The Duster was Cool and Awesome looking when you finished .I Really liked the Red Striped tires , they Set it off well.
I REALLY want that car!! I grew up around those things! As a grown up, getting older guy.....I stepped up to a 2017 RAM with the V8 hemi. I LOVE this truck! I swear I ride it like it IS a slant six. I work hard to keep it around 17 mpg around town.....20 to 22 highway....I can turn off the radio and listen to the engine ALL DAY LONG!
Yeah I was wondering about that. I did a disc conversion on my barracuda and had to use a disc brake spindle from a scamp. So I'd like to know where they got a spindle that fits.
Breathing is the key with the slant six. Oversize valves and a cam will really wake up the little beastie. Mopar 383 exhaust valve is a good upgrade for the intake side and is the same height as stock. Ford Ranger 2.3 exhaust valve will fit with the appropriate valve guide and minor machining for use with a Pontiac 400 spring.
@@1967davethewave I'd swap in a BMW m50 with a turbo, I'd guess that no one has done that. The engine bay is huge, can fit a viper v10 with twins with ease
Look on TH-cam for Argentinian TC, or Turismo Carretera, road racing series with Ford Falcon, Chevy Nova, and Dodge Polara/gtx, powered by the 6 cylinder engines. They’re pushing more than 400hp and almost 9000rpms out of the old tech.
@@alexstromberg7696 That would be a little more unique for sure but I think this video is about a guy who just wants to preserve the car as it has always been. Every Duster and Demon out there has a 340, 360 or a 440 in it anymore. I'm sure they're a blast to drive (I owned a 71 340 Demon that was real back in the 80's). But these cars with their underpowered engines are getting to be a rare sight today. It's kind of like killing off an era that was very special to some of us older folks. I'm not saying don't build these cars into hotrods, I'm just saying that anymore a good stock example is a rare car.
I remember when I was a kid on the farm, the 2 combines my dad used had a 318s. For a month, at harvest time, they would run essentially flat out, 12 hrs a day. And we had a swather with a slant six as well. I dont recall doing any work, other than mantinence, on either engine.
...... 1st time I viewed you guys... you're GREAT... simple - straight forward.... informative... clean clear shots... and best of all NO DAMNABLE MUSIC... GREAT ! keep on, keepin on !
They bolted up all that new powerful stopping gear to rusted out mounts. 6:23 I wouldn't let these arse clowns near any car of mine. First time those brakes are used in anger the front end will rip out.
I bought a 71 Demon with a 340. That thing was scarry fast. While I was deployed my wife rolled it. I still have the key, the license plate, and the wife.
Man the way they were just pulling those parts off makes me realize how easy it was to be a mechanic back then. I don’t want to work on todays cars. Everything’s been put in sideways 😂
@@boomerhgt Yea I'm a mechanic from the 90's and up, every time I take the engine cover off a Chrysler I say WTF too....LOL HAHA what is all this stuff !!!
I had a '69 Dart GT 340 with a 904 tranny and it was gobs of fun, but my most memorable times was riding around in my friend's '67 Coronet with a slant six with a three on the tree. His car was even a four door, but man, that car was the ultimate cruiser. He even had a '73 Charger with a 440, but the Coronet was still the go-to car for fun.
Love your show. Excellent video, lighting and audio. Always fun to watch a pretty basic car brought back to life. Straight sixes are great engines to make some improvements to thanks to modern pieces. The originals were often built to be cheap and easy to repair, but now modern sixes are built to the same standards as any other engine....they are no longer the bargain bin motor.👍 I do agree with other comments, you really should have steam cleaned the engine bay and all the suspension parts; kinda yucky seeing you put new parts in with old dirty parts.
Back in the 70s I had a Dodge van with a Slant 6 , that sound the starter made when you cranked the engine to start it was unmistakable , The van was shot but you couldn't kill that slant , thanks .
You guys totally get what a vehicle can mean to a person! The love /hate relationship that is involved in owning a car for almost half a century is akin to being married and this one is totally linked to this man's wife. What you did for this gentleman is just fantastic! This is why I love this channel!
@Lassi Kinnunen Interesting. I think you're right though Lassi. We're talking 40+ years ago I just remember that the speed thing was nutz when I was a teen driving it. It was a great car though. A Duster all black, with custom stripes down the sides, and a white top! It was so 1970's!!! haha. It was our first slant 6 car. My dad loved flooring the accelerator on a freeway on-ramp. Damn thing only had a 1 barrel carb but to him as a mid-sized car it was his speed machine! I really miss him. He was a gem of a dad. I was one of the lucky ones.
@Lassi Kinnunen I've rethought this. Yes you're right. To do the actual speed limits back then (highway speeds topped out at 70), the speedo showed 55. Thanks for the correction. Age is not your friend! ha!
There was no way to recalibrate one of those speedometers. They were manufactured with no calibration adjustment. Consumers just dealt with it. I remember driving a Dodge Ram Truck thing (Like a full sized Ford Bronco) back then brand new with monster tires from the factory, the speedo was just completely off. And this thing was brand new off the lot.
I rebuilt the 225 Slant Six in my 63 Valiant convertible and made 201 RWHP & 211 RWTQ . And it wasnt really expensive . I used a ignition system upgrade , custom pistons , bigger valves , did my own port & bowl work , had a custom cam grind done , 4 barrel intake & 500 cfm carb and header . And she runs really strong compared to its original performance
A 71 Duster was my first car. I got it when I was 14 and drove it until I was 19 and shipped out for the Army. I passed the car down to my brother who drove it into the ground. I never saw it again. It had a 198 and was just plain unstoppable

Back in the 80's when these cars still roamed the streets, we used to make fun of them. Now 50 years later, I'd drive that Mopar any day!!
In the 70s and 80s these cars constantly broke down
Everything on old Chrysler products was crap except the engines
The 80's? Yeah by the early 80's the Duster's that left were all rusted out with leaf springs visible inside the trunk. lol.
Back then we did not realize the cars of the future would have cheap aluminum engines with fancy computers that could shut your car down with a glitch.

Totally made my morning watching this...had 2 slant 6 Dusters in my 20s...best cars I've owned
"Replacing the brake lines is a must." Leaves the 1/2 way rusted through steel lines.
i caught that too. We know brake fluid mixes well with condensation, I'm betting the inside of those lines were rusted as well as the outside.
To be fair, there must have been a budget.
@@jondog9 nothing like running the now fast Mopar into a tree when a brake line fails.
they will all get changed. changing from drum fronts to calibers and a new master with more pressure will pop the old rusted ones soon
John so because you’re on a budget it’s OK to get killed or kill somebody else because your brakes failed?!
Pause at 8:15 and frame forward using the period key until the top wrench is removed. You can see that the bare brake line is shiny enough to reflect light and no rust is detectable. Looks almost new to me. The coil guard that protects the bare brake line tube looks cruddy from the spray undercoating and road dirt. Where is there a line rusted half way through? People will die?

@@ronschlorff7089 that "blue-flame-6 " weighed 40lbs More than the 265cu in V-8 in '55, 150Hp vs 195. I WONDER why GM didn't cast several-thousand 235L-6s in alloy!?! That would've dropped 80-100lbs, and would have made the C-1 a "More desirable" car, rather than the Rich-man's curiousity it is now. You Know if they'd done that, ALL of those alloy 235s'd be LONG gone.
Now that's my kinda project car. I wish we had access to these in the UK. Also the rim and tyre choice was absolutely inspired. Beautiful car.
My father had that in a van. Was a tank with 4 leaf springs and the tranny would chirp the tires going into 2nd when I was in high school.
I have been a professional transmission rebuilder for 40 years. I have built 100s of the 904/TF6/999 transmissions. they are one of the best ever made! only topped by the big brother, the TF8/727,,,,,,,,,,,,,,
Just too bad they couldn't have come up with an overdrive to go with this...
@@w41duvernay a518/a500. they are 727/904 with overdrive units, respectively.
My brother and I rebuilt a 727 for my 66 300! he was a tranny guy and knew how to stuff an extra clutch or 2 in many trannies, and which holes to drill in the V-body plate to get a better shift! Oh for the simplicity of the 60's engines! Very unusual car, 4dr pillarless with bucket seats, and a police interceptor 383, carter AFB, That thing would scream! Wish I still had it!
@Old Skool
I picked up a Torqueflight many, many years ago, which had a adapter to mount it on a small block Chev. The adapter was heavy as hell, adding a nice heavy flywheel, for more torque, to the SBC, it was bullet proof. It also had a B&M add-on where I could pull a knob, and adjust the, the... (old age kicking in).. I want to say they don't have a valve body, but I can't recall what they do have. I just remember I could pull the knob all the way out, and it would rev higher before shifting and shift harder... This was long enough ago, TH400 were still on the drawing boards! LOL
Since the car was recently repainted, they should have painted the engine bay while the engine was out.
At least they should have steam cleaned it!
Was thinking exactly the same thing !
I'm glad I was not the only one thinking that. I was sitting there the whole time saying what's the point of doing all that work if they're not going to paint the engine bay. At least paint it black or something to make it look good.
Steve Pratt Nooooo, not black! It's a Mopar. Always the body color. Leave the black engine bay to the Chevy guys!
Only pennies more to go first class.. I agree
Man that rebuilt slant 6 sounded great on the dyno.
Some perspective: That's less HP than a modern 2.0 Subaru flat 4 and only a bit more torque. A Crosstrek could take on this beast in the straightaway and utterly lose it in the twists ... but it wouldn't sound as cool.
@Raúl Saavedra Violante and, that “Stone Age” engine was easy to work on, too.
GREAT video for me. I was trying to save the Slant 6 back around 71. I worked in the engine lab at Chrysler. I really pushed a 170 cu in turbocharged package with a flow through head. Great memories. Big block replacement research was interesting too. I'll just say my Honorable discharge got me the best job ever.
Do you remember what kind of number that this made back then?
My 71 valiant slant 6 odometer rolled over still going. 😎
Old Mopar guy here. Great job on building the engine and refreshing up the Duster. I would tell you missed out on one part of the engine build, that is rotating the carb 90 degrees and having a plenum welded in the intake manifold so balances the gas/air mixture to the engine. The way it's set up now - the primaries feed the front cylinders and the secondaries feed the back cylinders . Makes a big difference!
Not experienced in building up slant sixes but the carb orientation didn't look right.
They made a lot of mistakes!
That explains the no where near 242hp
@@UltimateCARNUT it only made 95hp from factory so its doing good now
Where would you add the plenum--how large would it be? Could you separate a Holly projector-system, so you'd tap & drill 4 spots along the 6-armed intake-piece/manifold, then you'd have "port" injection?
“And to add a little refreshed nostalgia we took out the blanket/upholstery and gave it a good shake”
I gotta say, I am a dyed in the wool Ford guy but this is one awesome build that I would love to have in my stable. Sweet!!!

I can’t believe how much work they did for that gentleman. hats off to our guys. that was incredibly nice of you. !!!
OMG I loved this! I had a dodge Aspen for years and couldn't kill it . It had a bad fuel line, a seized tranny , broken front pax torsion link and the drive shaft fall out. All easily and economically fixed. That thing ran like hell . Thanks for the memories.
I had a Dodge Aspen also. 1977 model 2 door, 225 slant six and four speed overdrive on the floor. It use to get 27 mpg at 60 mph. Plenty of power with the manual transmission but no airconditioning on that car. Transmission got noisy in fourth gear. Today you would take it to a transmission shop. Only 12k warranty in those days and I had just over that, maybe 15k miles. So I pulled the transmission myself, replaced the bad bearings and reinstalled it. Perfect! Those were the days when you could fix a car yourself with mostly simple tools and some common sense. I didn't even have shop manual for the car. Wish I had it back today!
I bought a 1978 Dodge Aspen Custom Sedan with the 225 Super Six and A904 automatic 3-speed transmission with only 77,400 original miles on it May 14, 2021 it sat parked for 20 years and it's taken me a year to get it running again and I have put 66 miles on it .
Still has a slight engine misfire likely due to the cheap Carquest plug wires and Autolite plugs the owner's manual calls for Champion spark plugs and the engine stalls if shifted from Park to Reverse but if you shift from Park to Drive then shift to Reverse the engine stays running and the car moves but the engine sounds like it wants to stall unless you feather the gas when reversing.
@@roya.cathcartjr.5042 wish i could work on it with you. i knew that car inside and out
Really enjoyed this rebuild. Brings back a lot of memories wrenching on the old slant 6’s I’ve owned. Such an easy engine to work on and such a workhorse on top of it. Great job guys.
@MDS points aren’t too bad to change, but yes depending on the car it’s in, getting to the distributor was a pain in the rump that’s for sure. Slant 6 always had a vapor lock issue that was pretty common and annoying too 🤣
beautiful ! I'm a hardcore V8 guy , but I will admit, those slant sixes are smooth !
Actually with factory solid lifters they clatter quite a bit, but yes are smoothly balanced.
Yep had one in an 1984 D100 - gutless - 4 speed with OD - fun to shift gears - but no power and used lots of gas - but couldn’t kill it
One of my dream cars !
America has always had this incredible skill of being able to design and build an enormous engine that outputs a ridiculously tiny amount of power. This skill is virtually unique to the states. Impressive.
It was designed in 1959 and it had 145 hp at that time. It is also the most reliable and durable engine in the world.
Their figures are rear wheel wheel horsepower don't forget. And if you compare it to some eurocar, make sure you compare it to a coupe variant of a plain everyday family car of the same era. Oh, and while you're choosing a car to compare, get the smallest engine option like this one has.
I’m honestly impressed. It’s not often that you see mainstream Kroger brand hot rod TV shows build a car with something other than a Great Value Chevy 350.
Love the old 6 banger Mopar and Ford builds!
Dearly LOVE engine work and a “slant 6” is the engine that I learned on in auto mechanics class my high school senior year (1971) :-) !!
Everyone is just hating on them for doing it the right way and I'm just over here trying to learn 😂
I love when old classics get restored. Nice to know alot of cars are going to be around for much longer
Sweet rebuild, Guys. Growing up, my buddy had a '61 Valiant. I love that slant six.
In my junior year, my half sister's uncle Tony had a slant 6 exactly like this one except different year and color.
Holy crap that motor sounds really good lol.. I’m glad to see you guys “restoring” motors.. especially this motor
Haha I gather that was a VERY sarcastic comment, these c***s are all shit
The 1960's 6 cylinders were strong engines. Good motors.
60 MPH Sledgers to cruise.
I'm happy for Ken and I hope him and his wife enjoy this hopped up subtle Duster for years to come.
Best runners I ever owned were 2 Volares with slant sixes and a 65 Plymouth Belvedere. Thanks guys your meticulous. Really enjoyed both videos.
That owner deserves it, because he is so passionate with regards to the Duster
Dennis Weaver would love this engine under the hood
lol....nobody will get it...
Most of the Valiants in Duel had the 318 V8. I believe the only Slant 6 car used was sent over the cliff.
"He can't catch me on the grade!"
LOL
I Hadn't Seen a Slant 6 Since The Early Eighties. Thank You , it Brings Back Memories.
BMW I6 (Still very common) are technically slant 6es not I6 so i've seen some recently
The rebuild of the Slant 6 was fun to watch. Thanks for sharing!
Back in 1980, we bought a 1976 Plymouth Valarie stationwagon with a slant 6 in it. After getting out of the service and going back to SoCal, I decided it needed a little more getup and go. I found a 4 Blb manifold and a small 4blb carb to install on it. After I got it all set up and running, I took it for a few test runs and figured it just didn't do much for it. So I removed the carb and manifold and put the stock back in. I then traded it in on a 1979 Dodge Aspen stationwagon with a 318. It had a bit more power! :)
The mighty slant 6. In Australia I had 3 Valiants with this engine. The Dodge Valiant "S-series" , the VF And VG models. My all time favourite donk. Thanks guys. Very nostalgic
I owned two Darts. My first was a 1972 pale yellow, and my second was a light blue 318 for 1974. I loved the shape of the Dart and wished I had never sold it.
My first car was a army green 1971 Plymouth Duster with a slant 6 225 engine. That was the best car I ever owned.😁
It is good to see one of these old engines updated. There are a lot of these out there used in boats also.
Being a commuter and driving more than 100 miles or more almost every day my Valiant with the slant 6 was my go to vehicle. I did not know then there were different HP ratings . I wish I had one of your motor rebuilds like this super super 6 you built for my commuting drive time. I guess it is never too late to learn. Thanks for the great tutorial videos.
As a retired mechanic I say the 225 was the best engine ever on the road..... beautiful car.. fantastic job
I would proudly drive that car! Love the old slantys. 😎👍🇺🇸
Yeah, old inline sixes are nice when at their peak. I have a 200 in my 64 Ranchero, freshly rebuilt to spec. Runs like a champ, and with one Flowmaster, sounds pretty darn good too!!
Nice job on the Duster!
Haven't seen a Slant 6 in years!
Congrats
I’m impressed with the level of detail you guys are showing on the rebuild process for balancing etc. 👍🏻
That little car will handle better, drive better and set you back in the seat better than it was new. Nice job guys. Thanks for sharing the video post and best of luck 🍀👍🏼🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸
Thoroughly enjoyed guys!!! THanks.
I would clean the car first, before putting brand new parts on it, but thats just me.
I hate to do all that and have a motor mount fail.
@@tracyborn3517 Word, while you're in there, have removed the entire engine and are under the car, you might as well do some cleaning, if not just for aesthetic reason, but for reduced risk of failure too.
No, it's not Just you. It always creeps me out to see these shows like "Wheeler Dealers" (the absolute worst) bolt on new parts to a grungy greasy car!! Of course with "Road Kill", that's their "trademark"! Pressure washing ain't that hard,!! Hey, just get your "worthless son" to do it, ...and off his fricking phone!! Ha!! :D
No that's that's just millions of people, Not just you
These guys or who ever makes clips like these are very educational to people like us. I never knew about the weighing of the pistons thing I have seen quite a few clips on engine building but now that I know I will use it.good job 👍🏻👍🏻
At 4000 rpm, it's a waste of time.
Love how much y'all help others out and spare no expenses. The look on ppl faces ROCKS
I would have liked to see a test drive and the owner's reaction. It should have made a huge difference in performance.
Wish I still had one of my Dodge darts. 1967,68 with the 225 slat six put a header and intake on it and it was fast for a six,69, and 1971 with the slant six. love these cars and this video brings back some great memories. Thanks for sharing.
All nit picking aside, this was a good lesson in rebuilding a classic. I'm doing an 85 LTD, fun retirement project, so guys like these always give me good ideas.
Nice work gang, the upgrades really made the slant six shine, and purr.
My first car was a 71 duster. Had it 3 months then bought a 73 challenger with a 340...wish I still had both of them.
71 Swinger for me ditto!
Thought I was watching discovery channel with this production quality jeez it’s awesome
You Guys make me wish I Still had my 1973 Plymouth Gold Duster!!! It was equipped with a 225 Slant 6cyl with A/C ,a 904 trans , console shift, bucket seats, and a flip down rear seat. The paint was Red with a white vinyl roof, and white side stripes with the words Gold Duster in Gold Letters Below it.
That's the nicest thing I've seen anyone do.. especially for someone else..and so full of nostalgia and so amazing to watch..and the effort and professional application just so progressive in the final development.. kewl dudes..?
Awsome, I had a few slant sixes no complaints👍
"has an exhaust leak" yep, needs a new engine.
Dude it was making 11hp per cylinder.. yeah, it really did lol
@@pup9et Agreed, it's cheap and easy to do, don't take any chances with your brakes.
@@chopchop7938 lol its like only changing the right front brake pads and not the left front then wondering why the new pads wore out so fast or why the car pulls to the right when the brakes are applied lmao

But the eye candy it looks soo good
I enjoyed this Video. The Information was very Valuable. and The Duster was Cool and Awesome looking when you finished .I Really liked the Red Striped tires , they Set it off well.
I REALLY want that car!! I grew up around those things! As a grown up, getting older guy.....I stepped up to a 2017 RAM with the V8 hemi. I LOVE this truck! I swear I ride it like it IS a slant six. I work hard to keep it around 17 mpg around town.....20 to 22 highway....I can turn off the radio and listen to the engine ALL DAY LONG!
First car a 72 Blue Duster 225 with 3spd manual. Reliable and great ride. Thx for this vid.
6:50 - the drum to disc conversion kit fits B and E body Mopars... the Duster is an A body...
Yeah I was wondering about that. I did a disc conversion on my barracuda and had to use a disc brake spindle from a scamp. So I'd like to know where they got a spindle that fits.
Breathing is the key with the slant six. Oversize valves and a cam will really wake up the little beastie. Mopar 383 exhaust valve is a good upgrade for the intake side and is the same height as stock. Ford Ranger 2.3 exhaust valve will fit with the appropriate valve guide and minor machining for use with a Pontiac 400 spring.
Or just swap in a modern engine or a V8, non crossflow engines will never be good today
@@alexstromberg7696 Then you can be exactly like everyone else, lol!
@@1967davethewave I'd swap in a BMW m50 with a turbo, I'd guess that no one has done that. The engine bay is huge, can fit a viper v10 with twins with ease
Look on TH-cam for Argentinian TC, or Turismo Carretera, road racing series with Ford Falcon, Chevy Nova, and Dodge Polara/gtx, powered by the 6 cylinder engines. They’re pushing more than 400hp and almost 9000rpms out of the old tech.
@@alexstromberg7696 That would be a little more unique for sure but I think this video is about a guy who just wants to preserve the car as it has always been. Every Duster and Demon out there has a 340, 360 or a 440 in it anymore. I'm sure they're a blast to drive (I owned a 71 340 Demon that was real back in the 80's). But these cars with their underpowered engines are getting to be a rare sight today. It's kind of like killing off an era that was very special to some of us older folks. I'm not saying don't build these cars into hotrods, I'm just saying that anymore a good stock example is a rare car.
Awesome build guys. And helping the old Duster stay on the road.
The Chrysler 225 slant six and the Chrysler 318 V8 are two of the most reliable gas engines ever made. They both would last forever.
I remember when I was a kid on the farm, the 2 combines my dad used had a 318s. For a month, at harvest time, they would run essentially flat out, 12 hrs a day. And we had a swather with a slant six as well. I dont recall doing any work, other than mantinence, on either engine.
I can't belive you guys were beating on the torsion bar with a ball peen hammer... OMG!
Cudas to the owner for keeping the 'ol slant six. Good horsepower for the street plus decent fuel economy. Nice to see.
Good hp for the street? NO......
A Slant Six Dodge is no big thrill/But it's a car no atom bomb can kill... 😎
Bottom end torque. It'll move of the line quicker than a run of the mill V8, and the V8 won't catch up 'til the very end.

Love the slant 6! Had lots of them, better then a v8
Love your show. Excellent video, lighting and audio. Always fun to watch a pretty basic car brought back to life. Straight sixes are great engines to make some improvements to thanks to modern pieces. The originals were often built to be cheap and easy to repair, but now modern sixes are built to the same standards as any other engine....they are no longer the bargain bin motor.👍 I do agree with other comments, you really should have steam cleaned the engine bay and all the suspension parts; kinda yucky seeing you put new parts in with old dirty parts.
"May the slant be with you." :motor trend 2019
Back in the 70s I had a Dodge van with a Slant 6 , that sound the starter made when you cranked the engine to start it was unmistakable , The van was shot but you couldn't kill that slant , thanks .
You guys totally get what a vehicle can mean to a person!

What about speedometer recalibration since they changed the tire size and rear end ratio
My dad upped the tires on his 71 and to be doing 55, the speedo said 70mph!
@Lassi Kinnunen Interesting. I think you're right though Lassi. We're talking 40+ years ago I just remember that the speed thing was nutz when I was a teen driving it. It was a great car though. A Duster all black, with custom stripes down the sides, and a white top! It was so 1970's!!! haha. It was our first slant 6 car. My dad loved flooring the accelerator on a freeway on-ramp. Damn thing only had a 1 barrel carb but to him as a mid-sized car it was his speed machine! I really miss him. He was a gem of a dad. I was one of the lucky ones.
@Lassi Kinnunen I've rethought this. Yes you're right. To do the actual speed limits back then (highway speeds topped out at 70), the speedo showed 55. Thanks for the correction. Age is not your friend! ha!
There was no way to recalibrate one of those speedometers. They were manufactured with no calibration adjustment. Consumers just dealt with it. I remember driving a Dodge Ram Truck thing (Like a full sized Ford Bronco) back then brand new with monster tires from the factory, the speedo was just completely off. And this thing was brand new off the lot.
I assume they put the right speedo gear in it when they replaced the trans??
I just couldn't go that far without painting the Kmember and more.. to freshen everything up. But that Slant 6 looks great.
I rebuilt the 225 Slant Six in my 63 Valiant convertible and made 201 RWHP & 211 RWTQ . And it wasnt really expensive . I used a ignition system upgrade , custom pistons , bigger valves , did my own port & bowl work , had a custom cam grind done , 4 barrel intake & 500 cfm carb and header . And she runs really strong compared to its original performance
A 71 Duster was my first car. I got it when I was 14 and drove it until I was 19 and shipped out for the Army. I passed the car down to my brother who drove it into the ground. I never saw it again. It had a 198 and was just plain unstoppable
