I bought a used Dodge van with a slant 225 used. I ran it for years and customized the van. later on after the engine had 700K miles on it one rod bearing started clicking and it was a spun bearing, (but) I had to drive it 50 miles back home with the spun bearing and made it no problem 2 in the morning from the beach with a load of people in the van. Next day drove it from home to my shop. Ripped out the engine and started the rebuild. Van is still running to this day and this was 20 plus years ago.

[@timp21117]

When I was in college, my girlfriend had an A100 van with a slant six / three on the tree setup. We drove home one long weekend - about 300 miles or so - and when we got home the engine started knocking. We put it up on blocks, dropped the oil pan, changed out all the bearings, put the pan back, filled it up with oil and drove it back to college on Sunday. We kept in touch after college, and she kept the van and has given it to her son. It now has about 800,000 miles on it and it is still going strong with the bearings we put in it back in 1982. I love these engines and my interest was kickstarted when I saw the Torqstorm supercharger ad. I see an old Dodge truck in my future - powered by a leaning tower of power...

[@tacey01]

@@timp21117 I had a ‘64 A100 cargo van. Bare bones plain Jane. No windows. Three speed manual/slant six. Bias ply tires. Vertical clutch and brake pedal. So much fun. It would get stuck on level ground with any rain at all. Snow driving was interesting. Great memories of my junior college years.

[@jrichey98]

We had a Volare Stationwagon with a slant-6 that turned over 600K miles before the frame of the vehicle rusted out from under it. The engine was still running fine but the vehicle was too rusted and had to be scrapped. One of my favorite engines of all time.

Working up north out of a camp, we had a camp generator powered by a slant six mounted in a trailer. It provided power to the entire camp. A new fresh faced company bozo seen it and said its too old and needs to be replaced. A brand new Japanese Izuzu diesel gen pack showed up and was switched into power the camp. Nothing but trouble. Big time! When its 35 below zero and your power fails it becomes very serious really quick. So we brought out the old slant six setup and reconnected it. Ran like a charm. We took that new gen set and parked with all the old junk!

I'm a Mopar guy by birth , and slant 6 enthusiast since I was old enough to understand what it was and wasn't compared to other motors Mopar or otherwise . Fond memories of us pulling out buried Jeep's 4x4s and even a dumptruck with backhoe loaded trailer once ..on so many occasions that thing proved to a naive horsepower thirsty teenager the importance of having the right balance of low gearing , enough power... with emphasis on low/mid range tourque ... And the traction to convert it into forward motion with little fanfare for what seemed like not enough truck according to every stuck to the frame rails desperate fool or peanut gallery co driver or bystanders who's shiny piece of shit was on the other end of the tightened strap also buried in the failed attempt at rescuing his buddy.. dad pulled them out.. often like it wasn't even trying... It was almost like a low buck American unimog The old mans plain white standard cab short bed 76? 78?

Pretty sure they had a center locking diff , 272:1 low range ? And maybe lower than usual axle gearing but I may be mixing spec's up with the myriad of other Dodge trucks that my dad had... I digress ... That was a hell of a truck.. I think we determined it could do 85 maybe 90 tops .. puking it's guts out with a breeze pushing .. definitely liked the 60 /65 cruise speed , and ride quality was agricultural at best... Underwhelming but damn I would love to have something as close to that truck as I could find right now and I would never part with it.. Enough about my Mopar delusions .. what I love about this video is the obvious deep understanding and yet easy to grasp explanations of the little things like combustion chamber architecture to swirl or squish the mixture at tdc for optimal burn, exhaust manifolds tuned for ideal scavenging , intake runners tailored to provide a positive pressure pulse in relation to valve timing... This is the ingenious shit only a few guys dig into to really understand, to unlock the why and how engineers did something that way .. to recognize it , realize what they had to work through... and maybe add that little bit of extra they didn't think of ... Heavy duty science happening way before cad , obd , and all the modern technology like variable valve timing, variable length intake runners ,gated plenums, EFI direct injection and all that amazing shit we pretty much accept as mundane on motors today. ..

[@exploranator]

Better explanation of what happens in an intake runner: A) Intake valve opens. Exhaust back-flows a bit into intake port. It's why they are black up the port a bit. The higher the RPM, the less the back-flow B) Air piled up like a compressed accordian fights back and pushes into the port and cylinder. C) Intake valve slams shut, but lo, the intake mixture is still coming down the tunnel like a football team running through the stadium tunnel to get to the field, but having a door suddenly slammed in their faces. D) The intake mixture slams into the back of the intake valve, suspended gasoline droplets in suspension bail and keep traveling forward and start heading through the air towards the intake valve, the bigger, the faster E) A pile of pressurized air gets squashed, accordion-like, against the back of the intake valve. it starts to bounce back up the intake port and runner backwards. Pressure builds up, and depending on length of intake runner (longer takes longer, shorter takes less) the pressure bounces backwards towards plenum. F) is back to A) The "negative pressure wave" is over-emphasized. The positive pressure by the suddenly-stalled air all piling up at the intake valve is what makes over-100-percent volumetric efficiency possible. Which RPM you tune for will be the RPM at which the best balance of runner length (intake and exhaust), cross-section, and cam timing allow the pressure to be at the best peak for rushing into the cylinder upon intake valve opening. The longer the runner, the better it is for low RPM, as the carb experiences less of the reversion, and instead of bouncing back quickly into a mass of air that is not moving so fast in the plenum, the air bouncing back is opposed by the other air still heading in that direction from the longer runner. AT higher RPM, the time between open, inhale, move, slam shut, air rebound back, and then open and inhale again is shorter so the long runners are not necessary for maximum power. The highest pressure in the intake system is when the valve slams shut and the air moving at top speed is all train-wrecked against it.

[@johncheves4740]

One of the reasons it's hard to tune a Slant-6 properly is the fact that it uses three drastically different intake runner lengths. Looking down on the intake from above, you can see that the middle ones are much shorter than the outer ones, which not only makes it difficult to keep the mixture ratio the same for all of them, but remember how he mentioned the concept of sonic pulses? By altering the intake runner length, you can change the rpm at which the engine makes maximum torque. the shorter the runner, the higher the rpm where it makes maximum torque. The longer, the lower the rpm. The issue is that when you change the runner length, that typically affects carburetor tuning. Which is normally not a big problem. You change jetting and a few other parameters, and you're good. The problem is that you can't optimize carburetion for three different intake runner lengths. And, to make matters worse, the cylinders are making maximum torque at three different rpm's, which could have other implications, such as camshaft selection. Since you typically match cam specs to the engine's torque band, it's likely that the variation in intake runner length is going to make optimizing cam and carburetion specs to all cylinders impossible. The fact is that the Slant 6 is a compromised engine from a performance standpoint. You can spend a butt-load of money to make one put out 325 HP. Or, you can spend a fraction of that on making a 318, 340, or 360 V8 put out a lot more. And, it's heavy as Hell, weighing almost as much as a small block V8. And being longer, it shifts the weight a bit farther forward over the front wheels, which hurts traction and handling a bit. The point is that there are a lot of good reasons why the Slant 6 isn't often hot-rodded. Its claim to fame is its virtual indestructibility, not its power. And this guy Tony's excellent video does the best job I've ever seen of explaining what a Slant 6 is and isn't.

Something about the online 6's, they tend to last a long time. My first car was an 1982 5 series BMW W/a 2.7L engine, I drove it for 11 years. It had 387K miles when I sold it (it's still on the road today). I hit the rev limiter (6800 rpm) every chance I got, it always asked for more. The only thing special I did to maintain it was change the oil and adjust the valves every 3k miles.

On two separate occasions friends of mine and myself tried blowing up slant six engines, the first time we drained the oil and were doing neutral slams around the neighborhood in a 75 Dart but a u-joint snapped first, second attempt we hung one from a tree and rigged it up with a gas can with a gallon and a half of gas in it and stood there drinking beer while the throttle was wide open with no oil or coolant hanging there, my buddies dad came home during the attempt and just walked past us shaking his head saying "You boys need help", it ran out of gas before it blew. I spent some years at a particular garage as the principal engine rebuilder, between that place and other garages I've worked at I've been inside a lot of engines (back in the day) and I've NEVER seen the inside of a slant six engine, those things are without a doubt the toughest gasoline engines ever made for cars, motorcycles or anything else you can name.

I worked summers and weekends at a place called Butch's Sunoco pumping gas, helping around the shop and eventually driving the old wrecker. Butch used to take care of the yellow cab co cars and even in the late 90's they had a bunch of Dodge Diplomats and most of them had the Slant 6. Most of them had over 300k of city traffic and some had over 500k although by then they pretty much all had work done. Being young and stupid I quickly found out why nobody wanted to run the wrecker the first time one of his dodges snapped a torsion bar in the middle of a intersection. Needless to say my training consisted of Butch telling me a thing or 2 about the Holmes back between his second or third beer and his wife Betsy who was a Angel telling me to stay safe. It took a while but I managed getting it hooked and dragged back to the shop in time for Butch to tell me I was the new driver. We only did a few tows a week so I didn't mind up until one of the cab drivers fell asleep and drove off into the salt marsh.it had to be a good 200 ft off of the road in marsh mud. I don't know how other than probably doing everything wrong. But I got it out and back to the shop where I fell asleep in the truck for a bit until Betsy found me and sent me home. I was covered in Stank march mud past my knees. Betsy being a mom feared what mine would think about sending a 17 year old kid out at 3 am to pull a taxi from the mud. She took me aside and hosed me down before giving me a pair of uniform pants. I could tell so many stories about that place, it was like a big dysfunctional family and he was one of the last independent garage/gas stations around. But if you worked hard he paid you for it, if you needed something, he made sure it was taken care of and come Christmas there was a VERY generous envelope waiting for you with your name on it. I couldn't have asked for a better summer and weekend job and it's a shame theres nothing like it for kids these days. Although with some of these wankers thin skin and lazy attitudes they wouldn't last a day.

There are still jobs like these, but hard to find. Not as many for sure. I worked a small farm/ ranch for a old man that just needed an extra pair of hands. He taught me a lot. Called me his ranch foreman. Lol I learned to do things I'll never use again, but it taught me that I'm not too good to do any job that's necessary. I'm trying to bring my kids up like I was. Working, learning, and having fun doing it. Hard work has it's rewards.

[@beboboymann3823]

No, they would not work an entire day at it doing anything.....I've watched them on the job and mostly they stop and sit around eyes glued to their cell phones thumbs flying a hundred miles and hour sending and receiving messages to other worthless young ones disregarding paying attention to their jobs as well. If ya gotta hire help hire a retired person. They have years of work history and are appreciative of the opportunity to make some money and not sit at home all day like the young ones wish they could.

Uncle Tony, my first car was a '67 Dart w/ the 225... loved that car. But this finally explains why the car ALWAYS hesitated when stomping on the gas. But it sure loved a good power-brake!

Great video and excellent information. I love the slant six. Back in the mid 70's I had some buddies into Mopar. The oldest brother had a 68 Belvedere with a 225 in it... The guy was getting mid 15's out of it! And he wasn't done... The two slightly younger brothers had a 66 Baracuda with a 273 Commando engine backed with a 4 SPD. Power shifting from first to second was like stepping off a roof but it held its own really well. I hope you keep these videos up as long as you can walk. You are helping preserve the affordable hobby the way it was supposed to be. 👍

[@jacksagrafsky4936]

I had a 1963 Plymouth, Belvedere. It had a Slant six in it. Loved the car and learned a lot of how to repair cars from owning it. One of the problems with it was that most of the things that needed work were on the side of the engine that was on the wrong side.

[@ridewithgnr2116]

Jack Sagrafsky that, funny right there!

[@mfree80286]

Chrysler almost did that again with the 2.2/2.5 engines in the 80's, since they're slanted but not so severely. They wised up though, only things that'll have you on your back with crap falling in your face are the exhaust connector and the starter. Everything else is on the front or on "the shelf" (top of the manifolds). God though, frozen exhaust connector bolts... arms straight up, not enough room to get long tools or leverage, last one I did I had to cut the springs and bolts with a dremel...

I had a 225 with 3 on the tree. Never had to tear it down. It was all about timing, dwell, valve adjustment and fuel flow.

[@martinmummert5614]

Yep, same here. Mine was a 1970 Duster. First gear wasn't synchronized, but the slant 6's torque, combined with a slight bit of clitch riding, always kept the car moving. I later bought a 1974 Duster that was a 360/4-speed car. Like an IDIOT, I eventually sold both of them.

In 64, my parents bought a 64 and a 1/2 year Plymouth barracuda, with a slant 6 in it to 25 and we put a lot of miles on it with very reliable. My parents enjoyed the car but it came a time to replace it so when they did so I inherited the car. I had it for a long time. I did a lot of interior work on it. And I took the engine out 2 or 3 times with a friend of mine and we did lot of machine work on it. I got got it at that time and it was a car and an engine that I learned a lot from and so that's my connection with the slant six engine at that time

[@lsswappedcessna]

Repair schedule for a modern car: $1,000 today, $1,000 tomorrow, $80 next week for premium gas because every cheap grocery-getter seems to be a not-so-cheap, not-so-reliable four cylinder turbo now, $3,000 next 50,000 miles because aluminum and 1200 F exhaust gas temperature don't mix well (Aluminum pistons are the reason the old Saabs are often heard being floored, then let off, then floored, then let off), etc...

[@tomservo5347]

@@lsswappedcessna I grew up on a farm, and even agricultural tractors are going the same route. 4-cylinder turbo diesels are generally used in small to mid-size tractors that have no low-end torque. Add to this the special additive required for the exhaust, the special filter in the exhaust, low-sulfur diesel (sulfur was where all the power came from plus it lubricated everything) and it's a lose lose for the consumer. It's why old 6-cylinder tractors are still popular-you can still work on them without having to pay $1000 for the dealership to come pick it up and plug it into their copyrighted software program just to get an idea of which (usually electronic) component has failed. The middle class working man is rapidly becoming extinct. (By design.)

[@ford300rippergarage]

[@bmclemore8203]

@@tomservo5347 it's not the manufacturers choice, but government mandates on emissions etc. The reason they want the engines running hotter and faster is all for emissions. Basically they need to be run hard. Cummins has pioneered the emissions compliance for diesels and literally if you work em hard but keep up with maintenance they do their best. It's opposite of conventional diesel operation. The sulfur may have lubricated more, but the sulfur also contaminated the engine oil faster back then. Going to ulsd has allowed increased maintenance interval times. Sulfur content is one of the elements measured when pulling oil samples.

I have never had an engine explained more fully and yet understandable than this! I am only a former shade tree mechanic who understood his limits. I owned a 1963 valiant and a 1968 Dodge van with slant sixes. My uncle was an Plymouth salesman in the 50s 60s and said they never had a problem with that engine that it was bulletproof. The van made a family trip to Texas from Iowa more enjoyable as a mattress in the back allowed 2 children to sleep most of the way as we always drove that trip at night as it was cooler and less traffic through big cities like Kansas City. The gas economy was great!

But...I've seen 600+K mile Slant 6's with the same reliability if not better. I like the Slant 6 for its oddity, and its pure reliability stand point. Your in depth look into WHY it's reliable, why it's a good platform to learn on and generally, it's simplistic looks with heaps of engineering behind it is what makes it such a great engine. Thanks for diving into the meat and potatoes of the venerable Slant 6 Tony. Cheers! Zip~
