them slant 6s are no joke..... saw one in Bridgeport CT in a shop in an ancient Valiant, it had dual quads, asbestos wrapped headers.... they said when they would start that car the paint came off the ceiling.... Long live the Slant 6 !!
Back in the eighties I had a four door 73 Chevy Nova with a 250 straight six and it was a very high revving little engine . Let's not forget the Ford 300 either straight 6's can kick ass too.
The slant 6 had an awesome stroke to rod length ratio, stout block, lots of bearing area and roomy heads for bigger valves. They were over engineered to push heavy taxis and trucks, and are great platforms for power mods.
Knowing less than nothing about building power I managed to get over 360hp out of a leaning tower of power in the early 80s by doing the basics and every trick every hot rodder told me about engine wise... People who saw.my Duster swore on a bible it had a built v8 in it when it only had a bored n stroked /6... Later on put a mildly built 71 440 performance engine and hemi 4 speed in it and couldn't make as good a pass as the 6 with a 3 speed..
Not true. Best way to kill one is drive it in the rain. Lol. Never met a slant 6 owner that did not carry a extra D Cap and wd40 to dry the distributor out after drive thru a puddle.
Nah my mother bought a used '76 Plymouth scamp with a slant 6 had it almost 3 years never changed or probably checked the oil,that SOB was still running when she got rid of it.The used car lot said it took 20 minutes to drain the oil pan.Those engines were bullet proof.
Brian Patrick , back then you could buy silicone spray in a can at an auto parts store. That stuff always worked for me. I would clean up the distributor cap and spark plug wires and silicone spray them once a month and never again had moisture problems that would stall my slant 6. That engine is arguably the best six cylinder engine the USA ever made.
Slant six was created by putting a head with valves onto a block that was originally a side valve flat head. That is why the push rods were so long. My favourite six.
Also economical. Those long manifold ducts gave them perhaps the best fuel/charge distribution of any six around. Out performed the 170/200s from Ford by quite a bit. My only bitch was that the distributor was difficult to access for tune ups. When they went to solid state switching that issue disappeared.
When I was a kid the older mechanics at my pops shop said when those engines were on their last leg they would put saw dust in them and they would run for another 75 thousand miles. I don't know if they were screwing with me or not.
He wasn't screwing with you. My Dad was Chief Mechanic for Sprint Cars back in the 50s and I've actually seen this happen with my own eyes. He retired in the late 70s and opened his own Shop as a hobby. I had a Plymouth Volare with the Slant 6 and it needed rings. He put sawdust in it and it kept running for at least another 50K miles. Frame rusted out on it and I had to scrap it in the early 90s.
Ive worked in a couple woodshops through the years. The machines in those shops all last a long time. Its like the dust is good for them kind of a dry cleaner/dry lube sort of effect. Of course, inside an engine is another matter.
even at their time here, 160-180hp optioned high performance slants in the Chrysler Valiant Regals was well and truly over the heads of other competitors in their own time
Wow, just came across this, and happy to see the Valiant get a bit of recognition. I rebuilt a '61 Lancer wagon to serve my need for wheels in college. Put an aluminum block 225 ci slant-six in, from a wrecked valiant. That was in 1978. Great car, fuel sipper, but fun. My dad owned one from brand new, till a big automotive museum in Denver, CO offered to add it to their collection - after turning 275,000 miles.
My little (5 feet nothing) sister who is 73 now had one of these and drove grown men to tears dragging big V-8 super cars...the pushbuton transmission and that screaming demon engine came off the line like a rocket. One ran at Tampa raceway in the 70's and was said to have clocked over 9,000 RPM. Awesome little car, I'd love to find one.
That is one bad early Lancer. Love to see what some people think is a quirky body design, blast down the track with those big shoes on. Should leave some people scratching their heads.... thinking, "..and it's a six??". Beautiful.....
The idea that something with a slant 6 could go fast is mind boggling. My first car was a Volare wagon with a slant 6 and a 4 speed manual. The slant 6 was the only good part of the car, but it wasn't tuned up to make enough power for that size of car. 75 mph flat out, and it took forever to get there. OTOH, I once managed to coax it uphill, from a standing start, in third gear. Not on purpose, just screwed up with the annoying, sticking shifter. I suppose hot cars have 4 barrel carbs, so this one must have had a fractional barrel carb. It couldn't go, it couldn't stop, and it couldn't turn.
I worked at a Dodge Dealer where my Dad was a Tech when the Volare / Aspen came out. The engines in them were very choked by anti-smog equipment and crappy undersized 2bbl carbs. They were attempting to make the engines work with unleaded and the pump plungers in the carbs were made of materials that broke down in unleaded gas. They went through about 6 different compounds of pump plunger materials that got swapped out when cars came in that stalled under acceleration on right hand turns. My Dad had a friend with a Valiant drag car with a slant six, it had a custom split intake manifold with 3 2 barrel carbs as well as 2 3 into 1 exhaust headers.
Staged. No 300 hp slantsix can beat a Hell Cat with a 6.4L supercharged Hemi engine that runs 9.45 in the qtr stock from the factory. No driver can be that bad.
I'm 65 and I can't handle the future, ah the good ol days. Hell I'm a 16 year old who owns a 64 valiant and I can say, yes the tech is a good thing, because it makes more power. Only reason it lost here is weight
I was a mechanic back when the slant six was in its heyday. It was such a smooth engine with no vibration at idle. I remember having to rebuild the carburetors frequently. It was an incredibly reliable engine. Ford and Chevy had lousy six cylinder engines.
@belly tripper my first car was a 73 dodge dart sport with a 340 V8, but my first truck was a 1980 customized dodge truck with a slant 6 engine. It had no power, but it was a reliable bulletproof engine.
@@michaelhorn4540 That's because your 1980 was a lean burn engine.Dodge had to lower the compression ratios on their engines to run 87 octagne gas.When the lean burn unit would go out (and they would) I would swap them over to regular electronic ignition.Of course back in the day it was just a trip to the junkyard for a distributer and ecm.The lean burn 318s lost a hundred horse from the older LA models.I would always rip out the 65 amp alternaters and regulaters and replace them with a 100 amp unit.
My buddy had an 80s Volare with the slant 6 and it was slooow, but so was everything else in the 80s. My 4 banger, 4 door Mercury Zephyr would beat it 0-60 if you had a long enough road!
Mike LeMoine, the reason it was slow may have been all that pollution controlled stuff, required by law, choking it down. I noticed the same problem on my 1979 Volare, compared to earlier cars with the slant 6. Big difference.
@@jeromewysocki8809 Yeah they put those smog pumps on them and choked them with a tiny carburetor to increase fuel economy. They ran low compression too, just like the de-tuned V8s of the time, which were also pretty slow for the most part. A new Camry would give a late 70s early 80s Ferrari a good run if not beat it:-).
What in the name of God do you have to do to a slant six to make it beat a Hellcat? I guess the Valiant had a hell of a weight advantage, but still. When I was a kid I drove a 67 Dart with a 225. I had no idea...
it's called inertia. the crankshaft in those straight six motors are very heavy and with the flywheel effect at high rpm, there was no stopping it like what you see here on the take off.
They were actually a really amazingly powerful engine with a hell of a lot of unused potential. We had 160-180hp stock optioned engines in our Valiant Regals. They went like a cat with its tail on fire.
Biggest problem was the distributor cap was low on the "slant " side and it would stall out if you went through a puddle. Also the Plymouth factory brakes were ridiculously undersized and needed replacing every few months. Not fun for a 16 year old with his first car.
Man that guy had some major cash into the 6 cylinder Valiant,I’m sure it weighs less than half of the new Challenger, those cars need 700 horsepower to get that 4500 pound pig moving.
had a dodge van with a slant 6 , pushed a rod right through the block at 70K miles , went to the junk yard pulled a red slant six , replaced the blue one , took me a week , had that van back on the road like nothing happened , and I'm no mechanic , I also had a 67" Dart 270 model with the slat 6 , it was fast for it's size ..
The Hellcat owner drive his car off a cliff later that day after contemplating his remaining car payments and cost of insurance as well as being beaten by a slant six.
Biggest mistake Dodge made was moving away from the slant . I had a 225 for years and when I thought I was upgrading , I got disappointed several times , so no more Dodge for me . Sad when you think of all the wonderful things they could have done with some of their engines .
Big issue with the S-6 platform was emissions control, the final nail was the expense of casting the block, the mold for the S-6 were unique , which was the major financial advantage of switching over to the pile of crap La(block based) 239 V6.,
My grandpa said he knew this guy in like 1966 who would make 4bbl carburetor adapter plates for slant sixes and allegedly they were quite fast. Pretty impressive stuff for an "economy" car
In the 70's my brother had a 73 slant 6 Duster. Beautiful car, jade green, white vinyl top, white interior. We put a Clifford research 4 barrel intake on it and headers. Car was very quick.
@@northumberlandpost186 2015 hellcats did not run mid 9s hell the demon in 2018 could only run a 9.9 with the drag tune and kit installed. He got beat and it's because of one thing. Weight.
I had a 71 Plymouth signet.That car was indestructible.Till I took air at 65 over railroad tracks.Busted a leaf shackle.That car was also a cops blind spot never ever got pulled over.It was so nondescript my son wouldn't ride in it.
the slant six was slanted because the chrysler engineers wanted long intake runners and to make room under the hood for the intake manifold they designed the motor to lay over to the passenger side. the entire engine was designed for ram effect in the intake runners.
That 225CI slant 6 was one of the finest motors Chrysler/Dodge ever made. Ford made a 300CI straight 6 during that era that was also an excellent engine. Durability wise both were impossible to kill. Both were torque monsters. I bought a Wrangler Rubicon new in 2006, and it has 4.0 litre straight 6 in it, and it has proven itself as equal to both of those classic 6's from the past. V-6, V-8, yea right, I'll take a straight 6 any day...
We had a Dart with a slant six, and all that I remember about it was that we had to baby it when making left-hand turns from a stop. The stock carb would starve and you would be a sitting duck to oncoming traffic. :)
My brother had a '70 Dart with a 225, if it sat idling too long on a warm day it would do the same thing, adjusted everything on the Carb, no difference. Noticed the Intake was really hot. Put an insulated spacer plate/gasket under the Carb, problem never came back...
I'm a v8 guy all the way would never put a six in my rides but I was impressed at that run the 4.3 is another six that gets up and goes if built but the slant six had some noz shot to her only way he beat that hellcat
@@warrengreen3217 I'm saying they both have forced induction. The difference is the slant six(assuming it's a 225) only makes 145hp n/a. And the 6.2 hemi makes ~475hp without the supercharger. It probably costed a lot more to make that power in the /6 as opposed to a v8 would
I ran a 62 Plymouth slant 6 over 50 miles at 70 mph with no coolant. temp gauge pegged at 250, and it never even slowed down. The next day I fixed the leaky rad, filled it with water and drove it every day for 2 more years. The best thing about this car was, it only had one belt, and it could drive all day without it.
Late 80s, my friend's mom had a 72 Dart with a 225 that burned a little oil. One day she walks in and tells us the car died a few blocks away. We jumped in my buddy's Cuda and took a ride up there and found the dipstick clean and shiny. We got some oil, filled it up, sat on the trunk and smoked two cigarettes' each, and then gave it a try, started right up. She sold that car and we saw it in the neighborhood for at least another ten years.
Had a slant 6 in high school in a 71 scamp...My dad was a dirt track race,r..He show,d me how to make a 4 barrel in take plate for it and I made lot,s of lunch money after that with that car..My best friend use,d it one night and got T.Bone,d..We took the ol slant and put it in a 66 fargo pick up and just kept on get,in more lunch money...lol..Great motor..The 66 got stolen and I never seen her aging..I still miss that motor and truck..
its hard to beat a straight 6 for torque just above idle & reliability.thats why so many were used in farm & industrial equipment.i even saw a wood chipper powered by a ford 300 before.had an electric solonoid on the carburetor that only opened the throttle about 20% when under a load.
I know my Jeep Is not in the same class as drag racers, but I have the 4.0 in-line six, and at 218,000 miles it is running like a top and I don’t think I will ever get rid of it
And it's little brother the 240. Same as the later 170 and 200 Ford Six. Chevy 225 and 292's were no slouches either! We had a Studebaker Straight Six in a Silver Hawk, used to eat 289 Mustangs on the highway...
It held the land speed record in New Zealand for over 30 years. There was a moratorium on engine size. Dodge built Hemi heads, dual 4 barrels. These things would rock!
Look! I got the the high dollar badass version, nothing can outrun my new cookie cutter car cause that's what the dealer told me. Welcome to good old fashioned cut and try low budget know how it just left you staring at it's taillights. A little advice (Pretty don't make er' fast)
A friend of my Dad had a Valiant slant 6 drag car. It was over-bored, custom made cam, 3 2 barrel carbs, 2 3 into 1 headers. It also had a bid coffee can under the hood with a steel fuel line spiral in it filled with Ice before each run to prevent vapor lock. That car kicked ass.
And that my friends is why Chrysler ditched one of the greatest motors of all time. It was indestructible and extremely reliable and capable. My first one was in a 1964 4-door, 1-ton, Power Wagon that the USAF had beat the tar out of, and it was unstoppable.

I would clean up the distributor cap and spark plug wires and silicone spray them once a month and never again had moisture problems that would stall my slant 6. That engine is arguably the best six cylinder engine the USA ever made.
The sound of that slant is awesome
Only way to beat a slant6 is with a hammer.I know how tuff these engines are do I ever,but this just makes me proud !!!!
Slant six was created by putting a head with valves onto a block that was originally a side valve flat head. That is why the push rods were so long.
My favourite six.
Also economical. Those long manifold ducts gave them perhaps the best fuel/charge distribution of any six around. Out performed the 170/200s from Ford by quite a bit. My only bitch was that the distributor was difficult to access for tune ups. When they went to solid state switching that issue disappeared.
Those slant 6 engines ran forever and were practically indestructible. One of the best stock engines ever made. Cheap and easy to work on, too.
@@dougoverhoff7568 The parts for them are cheaper too cause they made so many.
@@arkansastrash320 Absolutely. They're real workhorses, hard to beat, and especially for their day. 👍
When I was a kid the older mechanics at my pops shop said when those engines were on their last leg they would put saw dust in them and they would run for another 75 thousand miles. I don't know if they were screwing with me or not.
not really, sawdust did that for transmissions as well!
@@Frostified and takes the howl out of diffs too
He wasn't screwing with you. My Dad was Chief Mechanic for Sprint Cars back in the 50s and I've actually seen this happen with my own eyes. He retired in the late 70s and opened his own Shop as a hobby. I had a Plymouth Volare with the Slant 6 and it needed rings. He put sawdust in it and it kept running for at least another 50K miles. Frame rusted out on it and I had to scrap it in the early 90s.
Ive worked in a couple woodshops through the years. The machines in those shops all last a long time. Its like the dust is good for them kind of a dry cleaner/dry lube sort of effect.
Of course, inside an engine is another matter.
@@neolithicnobody8184
Rear springs pushed up into the trunk?
Yeah a built slant will beat everything in the short run. Great mill.
I believe the only reason Chrysler quit making them is because We couldn’t break them?
@@kevenkullberg9955 that could very well be.
@@kevenkullberg9955 no it was due to the strict california emissions last used in ram trucks 1987 but went in to marine applications up too 2000
@@kylec166 thank you for the info. I would love to get one!
even at their time here, 160-180hp optioned high performance slants in the Chrysler Valiant Regals was well and truly over the heads of other competitors in their own time
Wow, just came across this, and happy to see the Valiant get a bit of recognition. I rebuilt a '61 Lancer wagon to serve my need for wheels in college. Put an aluminum block 225 ci slant-six in, from a wrecked valiant. That was in 1978. Great car, fuel sipper, but fun. My dad owned one from brand new, till a big automotive museum in Denver, CO offered to add it to their collection - after turning 275,000 miles.
The slant 6 was the best engine Mopar ever made. Bullet proof!
@@Future-Preps35 Another bulletproof engine! I have a 318 in my 1974 Dart Swinger.
My little (5 feet nothing) sister who is 73 now had one of these and drove grown men to tears dragging big V-8 super cars...the pushbuton transmission and that screaming demon engine came off the line like a rocket. One ran at Tampa raceway in the 70's and was said to have clocked over 9,000 RPM. Awesome little car, I'd love to find one.
That is one bad early Lancer. Love to see what some people think is a quirky body design, blast down the track with those big shoes on. Should leave some people scratching their heads.... thinking, "..and it's a six??". Beautiful.....
The idea that something with a slant 6 could go fast is mind boggling. My first car was a Volare wagon with a slant 6 and a 4 speed manual. The slant 6 was the only good part of the car, but it wasn't tuned up to make enough power for that size of car. 75 mph flat out, and it took forever to get there. OTOH, I once managed to coax it uphill, from a standing start, in third gear. Not on purpose, just screwed up with the annoying, sticking shifter. I suppose hot cars have 4 barrel carbs, so this one must have had a fractional barrel carb. It couldn't go, it couldn't stop, and it couldn't turn.
I worked at a Dodge Dealer where my Dad was a Tech when the Volare / Aspen came out. The engines in them were very choked by anti-smog equipment and crappy undersized 2bbl carbs. They were attempting to make the engines work with unleaded and the pump plungers in the carbs were made of materials that broke down in unleaded gas. They went through about 6 different compounds of pump plunger materials that got swapped out when cars came in that stalled under acceleration on right hand turns. My Dad had a friend with a Valiant drag car with a slant six, it had a custom split intake manifold with 3 2 barrel carbs as well as 2 3 into 1 exhaust headers.
You see, the older stuff is made way more better.
Not exactly.
Well, you said it so it must be true...smh
@@The_Gallowglass Proof? Oh that's right, you never had any....
Except that this particular one has been heavily modified with new parts...
For the first few seconds or until the first turn.
These new so-called muscle cars I think are highly over rated......But I don't like any of this new computerized bullshit any how.
the computer in the slant 6 is working well, while the computer in the hellcat went to Italy for spaghetti!!
Staged. No 300 hp slantsix can beat a Hell Cat with a 6.4L supercharged Hemi engine that runs 9.45 in the qtr stock from the factory. No driver can be that bad.
@@northumberlandpost186 they don't run 9s kiddo
I'm 65 and I can't handle the future, ah the good ol days. Hell I'm a 16 year old who owns a 64 valiant and I can say, yes the tech is a good thing, because it makes more power. Only reason it lost here is weight
Best part about a slant 6, no rev limiter to screw up your launch.
I was a mechanic back when the slant six was in its heyday. It was such a smooth engine with no vibration at idle. I remember having to rebuild the carburetors frequently. It was an incredibly reliable engine. Ford and Chevy had lousy six cylinder engines.
My dad had the Buick V6 in a Willy's Jeep and it could keep up with all the 8 cylinders while trail riding.
That's awesome, the slant 6 is one of the best engines ever made. My first new truck had a slant 6
@belly tripper my first car was a 73 dodge dart sport with a 340 V8, but my first truck was a 1980 customized dodge truck with a slant 6 engine. It had no power, but it was a reliable bulletproof engine.
@@michaelhorn4540 That's because your 1980 was a lean burn engine.Dodge had to lower the compression ratios on their engines to run 87 octagne gas.When the lean burn unit would go out (and they would) I would swap them over to regular electronic ignition.Of course back in the day it was just a trip to the junkyard for a distributer and ecm.The lean burn 318s lost a hundred horse from the older LA models.I would always rip out the 65 amp alternaters and regulaters and replace them with a 100 amp unit.
The "Leaning Tower of Power" Strikes Again!!😁👍👍
So tuff, in the owners manual under oil it said "optional".
Gotta love straight 6’s… wether they are straight up or leaning, they are just power houses
Dont think anybody ever made a bad one.
I love my 12 valve 6bt!!!
My buddy had an 80s Volare with the slant 6 and it was slooow, but so was everything else in the 80s. My 4 banger, 4 door Mercury Zephyr would beat it 0-60 if you had a long enough road!
Mike LeMoine, the reason it was slow may have been all that pollution controlled stuff, required by law, choking it down. I noticed the same problem on my 1979 Volare, compared to earlier cars with the slant 6. Big difference.
@@jeromewysocki8809 Yeah they put those smog pumps on them and choked them with a tiny carburetor to increase fuel economy. They ran low compression too, just like the de-tuned V8s of the time, which were also pretty slow for the most part. A new Camry would give a late 70s early 80s Ferrari a good run if not beat it:-).
I remember working on Slant 6s back in the day. The easiest way to change points and condenser was to take the distributor out.
I had a '64 Valiant with a slant 6, it was strong enough to break 4 clutch disks.
What in the name of God do you have to do to a slant six to make it beat a Hellcat? I guess the Valiant had a hell of a weight advantage, but still. When I was a kid I drove a 67 Dart with a 225. I had no idea...
been to MOKAN a few times got to see the valiant race 😎🏁🤘
Back when i had one, had an offenhauser intake that ran 3 dueces, damn thing ran like its ass was on fire, until the torsion bars let loose.😁
chryslers K-frame, made from tin cans.
My first car was a77 Plymouth volare with slant 6 . I never knew til now .
My '64 Dart had the 225 but I have to admit, it wasn't quite as fast as that. Maybe I should have put my foot down farther!
I cant believe you can get the much power out of a slant six
Robust bearings, heads and block...and giant turbo.
Before the Government started making auto makers put 'anti-pollution' crap on cars you could get all kinds of power under the hood.
it's called inertia. the crankshaft in those straight six motors are very heavy and with the flywheel effect at high rpm, there was no stopping it like what you see here on the take off.
They were actually a really amazingly powerful engine with a hell of a lot of unused potential. We had 160-180hp stock optioned engines in our Valiant Regals. They went like a cat with its tail on fire.
@ed miller government keeps you alive, huh?
Biggest problem was the distributor cap was low on the "slant " side and it would stall out if you went through a puddle. Also the Plymouth factory brakes were ridiculously undersized and needed replacing every few months. Not fun for a 16 year old with his first car.
All very true.
Spraying the spark plug wires and distributor cap once a month with silicone spray always prevented that problem for me. Great engine.
Legend has it is that the Hellcat owner is still in Hiding. 😅
If the Hellcat had big tire slicks it would have stomped the slant 6...just sayin...it was a pure hole shot win due to that fact.
I'd hide to if I could not drive any better than that or stage it for his buddy to win.
Man that guy had some major cash into the 6 cylinder Valiant,I’m sure it weighs less than half of the new Challenger, those cars need 700 horsepower to get that 4500 pound pig moving.
Grandfather Dodge is teaching little dodge some racing lessons.
my first car was a valiant i got in 1971 for birthday god i loved that car!
In all seriousness the Slant Six was one of the greatest engines ever !!!
if i owned that Hellcat, I would just give it away and go home filled with shame....hahahahahaa
Just goes' to show it doesn't matter how old you are when your bad ass your bad ass.
I used the have a 62 Lancer (my first car)........It might have made around a 21 second quarter mile if I had tried!!!!!!!
had a dodge van with a slant 6 , pushed a rod right through the block at 70K miles , went to the junk yard pulled a red slant six , replaced the blue one , took me a week , had that van back on the road like nothing happened , and I'm no mechanic , I also had a 67" Dart 270 model with the slat 6 , it was fast for it's size ..
Now that is hilarious. Can't help but wonder what the Challenger driver was thinking before, during and after LOL
hopefully crying, his "fancy" car just got beat by a 6 cylinder!!
It won't happen, it ain't happening, it didn't happen...I'll wake up in a minute.
To think how many low milege slant sixes went to the scrapper just because they were a six.
The Hellcat owner drive his car off a cliff later that day after contemplating his remaining car payments and cost of insurance as well as being beaten by a slant six.
And how much did he pay for that Hellcat Slant six put a whooping on that Hellcat
Old school rules love it
My very first car was a 1960 Dodge Lancer with the slant-six. It was not quite as fast as this one.
Biggest mistake Dodge made was moving away from the slant . I had a 225 for years and when I thought I was upgrading , I got disappointed several times , so no more Dodge for me . Sad when you think of all the wonderful things they could have done with some of their engines .
Big issue with the S-6 platform was emissions control, the final nail was the expense of casting the block, the mold for the S-6 were unique , which was the major financial advantage of switching over to the pile of crap La(block based) 239 V6.,
Great cars. The companies became greedy. They want us to keep coming back for service so now cars are designed to break down.
My grandpa said he knew this guy in like 1966 who would make 4bbl carburetor adapter plates for slant sixes and allegedly they were quite fast. Pretty impressive stuff for an "economy" car
In the 70's my brother had a 73 slant 6 Duster. Beautiful car, jade green, white vinyl top, white interior. We put a Clifford research 4 barrel intake on it and headers. Car was very quick.
I am a 1962 Model. Ha! Sometimes (many times) older is better! Where did I put my dentures...Hey! Pay attention to the drag race! ;-)
This is great stuff lol I bet the guy that owns the challenger is still trying to live this one down! lolol wooooooo
IT was staged. No 300 hp slant six can beat a 700 plus horse 6.4l supercharged Hemi from a Hell Cat. IT runs 9.45 stock in the qtr.
@@northumberlandpost186 2015 hellcats did not run mid 9s hell the demon in 2018 could only run a 9.9 with the drag tune and kit installed. He got beat and it's because of one thing. Weight.
@@northumberlandpost186 I was thinking same thing or a big shot of noz helped him down the track
@@justjamesAMX and t it lookd like the hellcat driver was late at the light
@@markb7906 right
The leaning tower of power. Do we know if the slant actually is a 225? Could be a 170.
I don't think it is a 225. Not from the 60s. I have a 225 in my 74 dart sport.
My guess is it's a "slant 6" but doesn't have stock anything.
can you fit a tall deck 225 in a valiant? I know the short deck 170 was designed specifically for that car.
Or a 198 too
My 68 Dart had the 170. Three on the tree
I had a 71 Plymouth signet.That car was indestructible.Till I took air at 65 over railroad tracks.Busted a leaf shackle.That car was also a cops blind spot never ever got pulled over.It was so nondescript my son wouldn't ride in it.
the slant six was slanted because the chrysler engineers wanted long intake runners and to make room under the hood for the intake manifold they designed the motor to lay over to the passenger side. the entire engine was designed for ram effect in the intake runners.
That 225CI slant 6 was one of the finest motors Chrysler/Dodge ever made. Ford made a 300CI straight 6 during that era that was also an excellent engine. Durability wise both were impossible to kill. Both were torque monsters. I bought a Wrangler Rubicon new in 2006, and it has 4.0 litre straight 6 in it, and it has proven itself as equal to both of those classic 6's from the past. V-6, V-8, yea right, I'll take a straight 6 any day...
Imagine if they built Bullett proof slant 6`s today
I had a built 225 in my one 1970 Barracuda. All it needed to be great would have been a better rear end gear.
I6 engines produce more torque at a lower RPM then V8s
Ya man, dad had a 61 dodge Lancer 3 speed stick on the floor. Car just ran and rannnnnnnnnnnnnnnnnnn! Slant six was awesome 👏 👍👍
The 60s had the good stuff. In America. 327s. 283s. 289s. 318s. 340s. 273s. 225s. Etc. And werent that bad on gas.
225 Slant 6, it just keeps on going and going and going. Ya gotta love 'em!
We had a Dart with a slant six, and all that I remember about it was that we had to baby it when making left-hand turns from a stop. The stock carb would starve and you would be a sitting duck to oncoming traffic. :)
brother's van did the same thing think it was float level gremlin
Sounds like a low float problem to me. The Slant six carburetor sits straight up vertical and it has nothing to do with the slant of the engine.
My brother had a '70 Dart with a 225, if it sat idling too long on a warm day it would do the same thing, adjusted everything on the Carb, no difference. Noticed the Intake was really hot. Put an insulated spacer plate/gasket under the Carb, problem never came back...
I love my 225 slant 6 mostly cause it ain’t got no freaking whoosy foreign commie “liters”. Neither does my 454.
🤣🤣🤣🤣🤣🤣
3.7 liters.
And 7.4 litres for the big block.
commie liters LOLOLOLOLOLOL
I was hoping for a patriotic comment like yours!
Thank you!
Show this to ever v8 snob, all engines can be great, and some just need more love
I'm a v8 guy all the way would never put a six in my rides but I was impressed at that run the 4.3 is another six that gets up and goes if built but the slant six had some noz shot to her only way he beat that hellcat
@@warrengreen3217 but the hellcat has a massive supercharger as well, so it seems pretty fair to me
@@skitzoid8202 I believe the hellcat was stock, I'm sure if u put the up grades to her it would blow the doors of that slant six
@@warrengreen3217 I'm saying they both have forced induction. The difference is the slant six(assuming it's a 225) only makes 145hp n/a. And the 6.2 hemi makes ~475hp without the supercharger. It probably costed a lot more to make that power in the /6 as opposed to a v8 would
v8 snob... this slant sounds more like a hipster thing
hell cat got smoked by a lil 6 banger! LOl hahahahahahhahah
I had a friend with a 70 dart with a slant 6 and that thing was almost indestructible.
My last new car was a 1970 Dodge Dart Swinger with a 6 cyl.
I ran a 62 Plymouth slant 6 over 50 miles at 70 mph with no coolant. temp gauge pegged at 250, and it never even slowed down. The next day I fixed the leaky rad, filled it with water and drove it every day for 2 more years. The best thing about this car was, it only had one belt, and it could drive all day without it.
Schooled by the little old lady from Pasedena.
That little leaner handed that one it's ass.
Chalk one up for the buzzin half-dozen.
Late 80s, my friend's mom had a 72 Dart with a 225 that burned a little oil. One day she walks in and tells us the car died a few blocks away. We jumped in my buddy's Cuda and took a ride up there and found the dipstick clean and shiny. We got some oil, filled it up, sat on the trunk and smoked two cigarettes' each, and then gave it a try, started right up. She sold that car and we saw it in the neighborhood for at least another ten years.
Had a slant 6 in high school in a 71 scamp...My dad was a dirt track race,r..He show,d me how to make a 4 barrel in take plate for it and I made lot,s of lunch money after that with that car..My best friend use,d it one night and got T.Bone,d..We took the ol slant and put it in a 66 fargo pick up and just kept on get,in more lunch money...lol..Great motor..The 66 got stolen and I never seen her aging..I still miss that motor and truck..
its hard to beat a straight 6 for torque just above idle & reliability.thats why so many were used in farm & industrial equipment.i even saw a wood chipper powered by a ford 300 before.had an electric solonoid on the carburetor that only opened the throttle about 20% when under a load.
It just goes to show you........
....
I know my Jeep Is not in the same class as drag racers, but I have the 4.0 in-line six, and at 218,000 miles it is running like a top and I don’t think I will ever get rid of it
Only thing tougher and more maintenance free is the original ford inline 6 300
And it's little brother the 240. Same as the later 170 and 200 Ford Six. Chevy 225 and 292's were no slouches either! We had a Studebaker Straight Six in a Silver Hawk, used to eat 289 Mustangs on the highway...
Gotta love that Mo Power. 😊
It held the land speed record in New Zealand for over 30 years. There was a moratorium on engine size.
Dodge built Hemi heads, dual 4 barrels. These things would rock!
My first car was a 1971 Dodge Dart Swinger,slant 6 it had no trouble doing 120 mph with no modifications.
Look! I got the the high dollar badass version, nothing can outrun my new cookie cutter car cause that's what the dealer told me. Welcome to good old fashioned cut and try low budget know how it just left you staring at it's taillights. A little advice (Pretty don't make er' fast)
How do they power up a slant six like that? I had a 67 Barracuda with a slant six. I never knew what I had...
A friend of my Dad had a Valiant slant 6 drag car. It was over-bored, custom made cam, 3 2 barrel carbs, 2 3 into 1 headers. It also had a bid coffee can under the hood with a steel fuel line spiral in it filled with Ice before each run to prevent vapor lock. That car kicked ass.
The Hellcat must race while it's new because the trans is junk. It'll be in the shop soon......
Slant 6 is a person who can build a racecar. Dodge hellcat is a person who only knows how to buy a racecar
When I was a kid; dad had a '63 Valiant slant six.......3 on the tree. You couldn't kill that engine.
That slant-six was one of the best automobile engines ever built. If that really is a slant-six in that lancer, it is really souped up.
Bad driver or staged. Can't touch a 9.45 sec Hellcat on cheater slicks.
brother had the same car with a slant 6 he put on headers and a small 4 barrel it was a monster from stop light to stop light in Visalia california
Sounds like an angry BMW.
Badass!
The Dodge slant 6 was the best engine ever made.
I wish they still made that engine. I loved it.
And that my friends is why Chrysler ditched one of the greatest motors of all time. It was indestructible and extremely reliable and capable. My first one was in a 1964 4-door, 1-ton, Power Wagon that the USAF had beat the tar out of, and it was unstoppable.
Had a 72' duster w/a slant 6...you could beat the hell out of those and would continue running.
Slant 6 ,the one engine I could never hurt. Close second was the 300 Ford.
Hellcat’s asleep at the switch - mouth breather. Probably pees sitting down.
