Engine Masrer’s supercharged one and it didn’t break 300 HP. I saw a video on a NA one with an exotic 3 carb set up. It fell just short of 300. For PowerNation to get 400/500, I’m amazed. That is over 100 more than what I’ve seen. The heads are not designed to be performance. Intake and exhaust on same side really hurts flow. The slant makes it almost impossible to to have the intake on one side and the exhaust on the other. I had so much fun rebuilding my 65.
30 seconds in... I had a Dodge AT114 225 Slant 6 manual, Dana 60... I had lost my Australian Ford Falcon XA GT Coupe (Hardtop), via Hardie Ferrodo's new "asbestos free performance pads" that i was recommended to try out through my specialist suspension handling business. Lost brakes, my car, a milk truck...yes...he T.boned me as I went backwards through a T intersection at about 90kmh with no brakes. 4 wheel discs, stone ground on the axle and hubs. So, I had a spare 351 Cleveland 4MAbc cranked engine and block..... manual FMX 3k stall, Dana built with LSD and 4.88 gears. I could smoke the custom duals from a standing start, FMX auto, retreads....and snake 4 rubber marks for 50plus metres. 😊
.....now im kinda wishing I had.... lol. I did my swap in 1991. This engine is sick.... Aussies build great stuff. Americans can do it far cheaper...so its awesome to see some of our best being shown. Well done guys
I built a forged crank 225 slant six that was bored to fit Mopar 2.2 liter dished turbo pistons on 198 slant six rods. Oregon Cams reground a stock cam for a little more mid-power oomph. For the valvetrain I used Ford 2.3 Ranger valves and machined the head for Pontiac 400 springs, and did a "bowl hog" on the intake side. For carburation I used a Holley 350 CFM on a modified Super Six factory intake. Spent gases left via dual Dutra manifolds, which made it necessary to use a Dakota V-6 starter. The stock distributor had lighter springs added for more initial advance, and I used a big block timing chain. I also adopted a GM HEI ignition feeding a Ford Taurus e-coil. I had it hooked to an A833 4 speed. It made about as much power as a stock 5.2 Magnum, but it was different! And it was definitely a lot of fun making something that not everyone else had. I'm glad I got to take my dad for a ride before he passed away in 2020. He was a dyed-in-the-wool Mopar nut.
I couldn't believe what I was reading! Absolutely loved seeing this. I used the same pistons and rods in one of my builds back in the early 90s with my 66 Valiant 2dr. I used bronze bushing in the small end of the rod to float the pins for the turbo pistons. My valves were stainless replacements from Racer Walsh for a 2Liter Fords. They had the smaller diameter stems, but were a larger valve diameter and they had to be .100" longer than original Ford length. Used a Erson Flat Tappet Cam from my earlier 170ci build, yet had it reground to a roller and used 440 roller lifters. Fully ported the head. The carb was a Holley 390CFM Vacuum Secondary with 125hp nitrous plate between it and the Clifford Intake. Homemade headers using the flanges from an old Clifford set I picked up at the Daytona Swap Meet. Ran a Mallory ignition box and distributor. Built a 904 tranny with a reversed manual valve body. It still is the one engine I had the most fun building and racing with. Nobody could ever believe that it was a slant six until I opened the hood. Thanks for commenting PapiDoesIt, this brought back some great memories and motivated me to make my first youtube comment.
@@pauljcampbell2997 My father put a 283 V8 in his 1968 Land Rover short-wheel base, five years before Land Rover and Range Rover did it, we also had the 360 here as well. And, Ironically The Range Rover V8 was based on a Hemi design.
@@wolfhobbies was gonna say probably slide ruling day I was born in Aug in 57. You know someone was doing something in several departments for that, they used to drive them a few months, trying to find out everything they could. Chrysler especially, in most, don’t understand why not 7 main , but they don’t have much of problems with it
@@davesturman1503I drove an Oldsmobile 350 with spun bearings for over a week to work and back. The bottom-end would be SO hot by the time I got to work, that the motor would be seized after I shut if off when I got there, it wouldn't crank over anymore. An 8 hour shift later, she'd turn over again and run long enough to get back home. After a little over a week of this routine, the big ends of the rods wallowed out large enough so that the rod bolt nuts started scraping the inside of the oil pan. It didn't take long before they scraped a hole in the pan, and I started losing all the oil. At that point, I just put it to the floor in park, and put it out of its misery in a spectacular fashion, and scattered rods all over my driveway. That motor was a tough S.O.B. though, to be able to go thru that abuse.
I'm a big block Ford guy and this was one of the coolest most interesting builds I have watched on your show. Keep it up this was great. Really love the creative ingenuity and tech skills shown.
Absolutely the best engine Chrysler ever built. Had four 225's and one 170 engines, The last was '81 Dodge truck, super six (2 bbl) 2.5" exhaust. MSD 6 / MSD coil. MSD copper plug wires. plugs gapped at .065. 22-24 MPG with O.D. 4 speed. sold with 400,000 miles to a guy in Traverse City Michigan. Last I knew it was past 500,000 miles when I lost track of him. Had to pull the head at 350,000 miles and replace number 6 exhaust valve with full clean up & valve job. Just an absolute great engine ! There is a buddy in Thawville Illinois with a Dart that has a turbo charged slant six from 30 years ago. Lots of slant six fans out there !
It's funny to see Frankie slowly becoming Pat's protege. Before you know it Frankie will have a pocket protector, goatee and receding hairline just like Pat.
He doesn't have a receding hairline, he has an advancing forehead, on account of all the magick and engine sorcery he's trying to keep contained behind it.
I had an uncle (r.i.p.) that started built Mopar motors back in the late 60s. Back in the early 90s I drove a 71 Dodge Dart with a slant 6. One of my uncle's buddies was an eccentric guy that built up a slant 6 with a supercharger, he sold me the engine and we swapped out the drivetrain in my 71. That thing was a beast, had to be putting out 500h.p. All the street racers at the time were mostly running foxbodies with that 5.slow. it was too easy taking their money if they were stupid enough to try.
You should look up the Ford 240/300. Guys make 300HP on them naturally aspirated. The evolution of that engine is even crazier, look up the Barra. Thousand horsepower is common on stock parts.
If I remember, he had a phobia of going really fast (like vertigo or something would creep in at 70+). If he could keep that in check all he would have to do is drop a gear and dissapear.
@@harrylister804 They have "crumple zones", or "sacrificial structure", so I guess the poor little Plymouth became a "sacrificial crumple zone"!! 🙂 (And, always carry a briefcase to jack yer gas pedal, if you find yourself in the same predicament)
Aussie here. I had a stock-standard 3-speed auto 1966 VC Valiant with this engine during the 1980's and I LOVED it. I drove it back and forth between Sydney and Brisbane a lot, Broken Hill and Adelaide one time, down to Canberra & Melbourne - and fully enjoyed it every day. It didn't seem to matter that it had drum brakes, no power steering, nor air conditioning. There were quite a lot of them getting around in Sydney, and then in the 1990's they faded away, and now are a rare sight.
@@bigboreracing356 these engines were reliable and did everything I needed them to do including being economical to run right through the two gas crisis in the 1970’s while thirsty V8 were expensive and impossible to run when gas rationing was in effect! I was able to drive and give rides to and from my high school for my Motörhead friends, with no sweat on the rationed fuel I was permitted to buy. If you don’t remember whether you could buy gas was based on the day of the week and whether your license ended on an odd or even number, and was limited in how much you could buy. With a Duster, and a 16 gallon tank, I did not max out the gallons portion of the limitation and getting 25 on the highway and 22 on the freeway sure helped as well!
@williamchapman2434 I had a 73 with the slant six when I was in high school. Loved taking it to car shows, and always opened the hood. Everyone else had dressed upped engines, but I got many compliments for just keeping it original
@@gabec2494 there are Chrome Valve Covers, split 3 +3 headers for dual. Exhaust, Super Six Two Barrel aluminum cast intakes and a Carter 2 Barrel to get a little extra fuel and air into those six cylinders!
First, I love Lake Speed Jr's knowledge and enthusiasm. He is an ace. Then there are plenty of comments about how much power an old engine design made, but this is the beauty of turbocharging these engines, they push the air in there and overcome some of the deficiencies while preserving some of that low end that they were known for. That is not to take away from your porting and planning. That was key as well. I particularly like the save you guys pulled to get the forged crank in the cast crank block. Good work!
My pop had a 78 Plymouth Volare with the straight six. We put 238K miles on that engine and it didnt burn a drop of oil and always started up right away in the morning. Truly a great engine!!!
This engine was originally designed as a reliable do-all machine mover: cars, pick-ups, boats, sawmills, off grid electric generator, you name it. What you guys did with it is truly AWSOME. I loved my '73 Duster with its slanty-six. Chrysler should have used a good cross flow head on these right from the start. Never dreamed it could be so capable with 21 century tech.
I had a 72 Duster with a slant 6. I spun the main bearing and still drove for miles before it died completely. Imagine racing a big block and win with a slant 6 with those numbers on the dyno.
I think a hemi head based on the Toyota 2TC and 3TC could work on a slant six. The pushrods are on the passenger side of the block. The 3TC can be bored to 3.50-inch with good sized valves - although it was only a 1.8 four with 75 hp stock, but when modded can make 600 hp. The custom head could use Toyota valve train parts -there is still a T series niche aftermarket - billet heads, big valves etc.
@@timothykeith1367Just the way they built it, it's 600 hp capable, they were going sooo easy on this setup. Send that boost up to 18 psi and watch, 600+ hp or more. The internals are all top notch, and it didnt even blink at that 11lbs.
😢@@izzyplusplusplus1004 The 3TC is a 1.8 liter four. When extrapolated to a six it's 2.7 liter - about the same displacement as the 170 slant six. I'd like to see just one built. It would not be popular on street Valiants and Darts because the intake manifold is on the passenger side, but I think there is as much space as the original Corolla had. That aftermarket billet heads were created is an inspiration. A 700 hp turbocharged 3TC can break the block, block damage could also be a problem with a slant six. On the 3TC a main bearing support "girdle" is custom made. It's cool what they can do with the 80 hp economy motor.
This and the ford 300 have been the most awesome videos I have seen. I love the creativity and ingenuity that goes into these less common builds. You guys set a world record in my book, 400 hp and well over 500 ft-lbs of torque with 11 pounds of boost is wicked. I would be curious to see what it does with 15 pounds of boost. I guarantee the power numbers would be a record 😉
No Brasil tiramos 2000HP dos motores GM 6 cilindros 250s (obviamente carros de arrancada que usam esses motores) o motor GM 250s veio originalmente no chevrolet opala que na época era concorrente do Ford maverick que usava um v8 302 e do dodge dart/charger RT que usava um v8 318, o opala era o mais leve de todos, o opala SS tinha 171 hp contra os 200hp maverick e 215 do charger RT, o opala era mais rápido pois do pesava 1190kg
Awesome engine, I turbocharged one back in 1978 and ran 14lbs of boost into it. It kicked so many big V8 butts. It was pretty much standard other than a Holley 350 and O-ringed head and it held up really well as long as I kept the water methanol up to it and used Super Fuel.
I was around and at Chrysler performance back in those days. Ps I think we made the head gasket leak at 16 lbs, but it didn’t fail. So much to all this.
@@4406bbldb actually I think it was my block I o-ringed, not the head. I ran it with an 18lb boost spring in the wastegate for a little while but it made me nervous for the engine :)
Dropping this into a light A-body like a square body Dart with a 5 speed would make an incredible track day car. With overdrive, an eco tune, and a sane 3:55 rear gear, mileage above 25mpg wouldn't be hard for a great track and street package.
I have a 1974 Dart Custom that could use a buildout like that! It would be a grandpa sleeper for sure! Do you guys wanna sell it? Sure would love to have it or the current Slant 6 built out just like it!
An extremely impressive build, gentlemen. What is more impressive is that in its current configuration (11 lbs boost) it is still very street able. I have no doubt that if you want to go racing you could get more power by turning up the boost...but I got the impression that you guys were aiming to build a better, driveable, “leaning tower of power”...awesome. I think you have very successfully achieved your goal. Great work!
You guys have absolutely killed it! Frank, Pat, and to all of you at PowerNation, Thank You! The whole year it took of planning, sourcing parts, and the convincing it took to get this project, I could only imagine. I just want to say, it has all payed off, and you guys should be proud. Not once did I skip the video, and your guest that you had for Piston Rings, and Fuel Injectors was a great choice. Whatever the vehicle choice may be, like a W250, or a Dart/Duster I'll be Looking forward to what you guys have in store for that awesome Slant!!
WOW you guys just set the Slant World on its head. What a Great collaboration of engineering and partners to pull this off. You have truly built my Dream Motor!
@@jameskuenzi9932Direct Connection used to sell a kit that included the intake headers lifters and cam to to make the 225 a lot more powerful but not as much as these guys went
Thank you for this build. Just because the average Joe can’t budget a build like this doesn’t mean that you can’t enjoy what can be done with “old technology “ when budget constraints don’t dictate what you can accomplish. I love straight six engines and I personally think that there’s a huge market for plain Jane work trucks with straight six engines tuned for torque and a minimum of high technology add-ons that are running costs through the roof for new trucks.
@@prevost8686 well for one the B58 is a definitely a tuners favourite engine though, I mean I have guys who are running a 650-700hp F30 340i, and some G20 M340i owners hitting 1000hp safely on just a stock crankshaft,to say the B58 is bad,is not exactly to say
@@bigboreracing356 honestly that sounds like quality content, like when Finnegan and Freiburger took the super bee and crusher Camaro thru heavy LA traffic
At 16 years old in 1970, my first car was an early 1960 Valiant V200 (the birth of the Slant-Six,) which I bought for $100 that I earned as a fry cook at KFC. I fixed it up 100% with pick-a-part used, and economy new, parts, and High School Auto Shop know-how. The adventures we had in that car are too numerous to list. Later when I had a "Data "Processing" career, I was always buying cool old cars: 1958-1961 finned Cadillacs, old pickups, a Falcon convertible and Ranchero, even a Jaguar XK140. Life happened and I don't have them any more, but the car I miss the most is the '60 Valiant. Watching this video, how could I not picture my beloved Valiant found and restored better than new with this marvelous motor!? (Heavy sigh...)
As one of your viewers, who requested this build, thank you! Freaking awesome - such a bad ass little in-line six. But, want to see some more juice out of it.
@marshallwilliams4054 would be really cool. I know Saabs made peak Torque at even 1800RPM and peak HP around 550. But that was like 230HP out of a 2.0 with 11psi of boost
Great informative video guys. No BS, no "attitood" just build it right. Results tell the whole story. That would be a terrific street engine in an old Mopar. Bags of cred there.
Frankie is now sportin a Pat pocket protecter with all the fixins. I really like this pair. I don't like to miss an episode. Keep up the good work guys.
The slant six, in many variations, had a production run of about 23 years! I had one 1963, in a Valiant. Great engine. It was known for its durability and ease to work on. It was also placed in tractors and boats. The Australian s had their own variation. For the cost to buy and operate its one of the very best.
We had a 77 D100 with a slant 6. It was used and abused, turned into a a trash/farm truck in the mid 90's before rust finally got it. But the motor never died despite how poorly it was treated and maintained. Great choice. This along with the other inline 6 builds are by far the most interesting and cool videos on the channel.
I've been wondering for about a year now what the potential is for a nice Slant Six build with those Aussie Speed parts and a turbo.Very satisfying result! Great job guys!!!
The "Tilley VC Valiant" had a Slant with 635hp, a decade before the AussieSpeed stuff came along. Now, with those big manifolds, a better Dutra-into-turbo section, and ports like Pat got here, the limit is going to be the temperature drop the intercooler can achieve. Even up to 90 thou over, a Slant block will handle more boost - There was one on the Aussie "MoPar Forums" back 20 years ago that was 120 thou over bored and it cracked the bores at 17psi boost. "Potential" will be, what cost more, this build, or a new Hurricane crate motor swap :)
Our first decent family car was a near new AP5 Valiant back in the day. My father loved it. After 20 years it was still going strong until some octogenarian went through a Stop Sign and wiped it out. I swear he shed a tear when it went to the wreckers. Today it would be worth a mint and repaired. I send him all these RUclips vids on highly tuned slant six engines and he loves them. Hard to believe that 60 yrs after he first purchased his, it's now out of his reach to buy another.
This engine looks like so much fun, I was so close to buying a 265 Hemi to swap into a Volvo 245, but snapped up a Volvo 164 to satiate my 6 cyl desires. Yella Terra and Aussiespeed are great Aussie companies I'll continue to support.
Guys this is truly awesome, brings back memories when I had my 71 225 Duster. and did some mods to it but never at that level that you guys are doing I guess it's because the parts were not available unless you had a 318 340 or 440 V8, so I thank you guys for doing a build like this just for the sake of possibilities of what could have been back in the day👍
Man, I wish I just had a little bit of y’all’s knowledge about Engines. I can get just about any small Engine running good Stock. But improving above Stock is out of my League. Amazing what you did with the old Slant Six. I would’ve never guessed you could get that much Horsepower and Torque from that Engine. Way to go Guys.👍👍👍👍👍
I am so impressed... Back in the 1980s I had a 1967 D200 crewcab with a 225 in it which was slow as christmas but would pull all day. Wish I still had that rust bucket. ;-)
As an Australian my Dad had one in his highly original AP5 Push Button ( gears ) Slant 6 ... 225. In the 1970's This build is perfect . 11psi av is XCELLENT
Having worked on these engines, what you’ve done is so impressive! Can you explain how you hooked up the oil line for the turbo? For a Dyno, the oil pan works. I would suggest a baffle when placed in a car. One small turn or a hard launch and you will lose oil pressure. Once that’s gone, no bueno. What a build. Would love this in my 65 2 door post Dart. What a sleeper. You guys are awesome. ❤❤❤
Holy hell. I ran a 225 slant six back in the mid - late 80's with Clifford industries goodies and a custom Racer Brown cam. It was in my 1965 Dodge Dart and was a very consistent ET drag racer. It wasn't super quick ( 13.56 best ET @ 89 mph. ) but it would hit that number nearly dead on all night long. It sounded like a full blown stock car ( the race kind, not a stock vehicle! ) It was also my daily driver ( as it would be back then I suppose ) Good times.
13 second 6 banger is impressive but back then? Thats what you call a sleeper Even seeing a turbo 225 today Id never guess it would make that kind of power. Muffle that sucker down and take peoples money!
@@gordocarbo I was fortunate. My uncle was a former indycar crew chief and avid endurance racer ( Dakar et. al. ) He did all my head work and used motorcycle tricks on the valves ( back then multi angle valve jobs beyond 3 were virtually unknown. ) I was just at 11.75:1 compression as well. I used a mini-spool that was a pain in the ass on the streets, constantly chirping when I'd make left or right turns. Before the Alston boys split I had them do my rear end. 4 link with auburn gears. Ron Souza@ ADCO Transmissions handled my tranny. All this was in prep for an eventual 383 swap - which I did and that's when the trouble started ! :D My slant 6 ended up in a tractor at my ex girlfriends dads farm. I did street race my lil white beast but I was small potatoes to be honest. There were legit 9 second street cars here in Sacramento in the late 80's
This is absolutely amazing. The first engine I ever built was a /6, and while it had a couple of small tweaks (Super Six intake, 2bbl carb, hotter ignition, and a little cam,) this is just 100% mental. I could see this in an Aspen woody wagon with an 8-3/4 rear and a 5-speed absolutely blowing peoples' minds at the strip.
👍👍👍👍👍👍😀 I was in my teens when I first drove my dad's 225 slant six. Good torque and smoothness out of the factory in a 1971 blue Dodge Dart 4 door sedan. The only problem was they have drivablity problems in low atmospheric pressure during rainy and snowy seasons. Mainly, it's those ancient poorly designed mechanical carburetors that use low tech vacuums assist systems ruined the drivibilty. Causing it to stall frequently during morning cold starts. I always wondered what if those fuel systems would be improved someday would be like for the 225 cubic inch Slant Six. This show has brought my early teen's imagination to real life . With the much improved quality of modern day fuel delivery system, latest ignition system, plus the awesome turbo added on a custom tuned & refined engine. It's impressive enough just normally asprirated in this show. Back then, it would be a dream or just a nonsense.
Those engines are damn near bullet proof. Im more a v8 guy but i gotta admit these str8 6s are str8 up stout as hell. Torque monsters. It should last a very long time tbh
You guys are knocking it out of the park lately. The boosted Chrysler 225 success following on from the unbelievable power output of the aspirated Chevrolet 400 SB from a couple of weeks back has blown my mind. 👏 🍻
Pat, Frankie, this is too cool! I'm all about V8 power, but these inline 6 cylinder builds you guys have been doing are pretty stinking awesome! They got me thinking about what else could be built.
The 225 slant six is one of the best motors ever built in any class. I've seen them run 1/4 million miles without any lower end problems. I've also seen one run 100's of miles with the main bearings so shot that the harmonic balancer was slapping the front of the block. I've have two different cars with one in them and they were insanely dependable. And some people remember they were retired but then brought back in the 80's when Dodge needed a six cylinder for truck applications while they developed a V6 for that use.
Hey Pete. Love your channel. You could just put up a disclaimer at the start of your vids? I’ve been a mechanic for 30 years and I learnt in workshops like yours….learnt the right way and I learnt the way you often have to do things when in the bush. It’s the true art of engineering. I was an aircraft engineer for the last 18 years and worked on modern jet aircraft, everything you do is IAW with AMM. But I never forgot where I started and you and I both know that the shortcuts are fine if you understand them. The naysayers are always those who seem to be frustrated that they can’t work out the true art of engineering. You are a bloody good bloke and thoroughly earnt employee of the month award! Catch you in Cooktown mate…look for the Perentie without the tourist stickers. Cheers
Thanks for what you guys do I know you probably do it for passion and love to work on these rebuilds but I’ve learned so much and it’s fun watching these builds as well. Your doing a lot of people favors that work from their garage
Very impressed guy's! Thanks so much for putting this together for us. I can't wait to see what you two put this in and hopefully you'll make a video of it on the strip.
Love the episode. I grew up around these engines. Mom and Dad bought a new 64 Dart wagon when I was 9. Got driven to Minnesota and back and Alaska and back from L.A. It got handed down to me as my 2nd car after my brother abused it for several years and swapped out the original 170 for a 225, and then a 273 v8 (cam, HR, dual ex). I drove that wagon at 90mph for about 2 - 3 hrs straight one time through central CA. and got the best mpg I ever got. (273 rear end). Later I had my dads 73 225 duster at the end of it's life. I only put used oil in it after the oil light would come on for another several years, wore the brakes out till the left rear shoes were gone and the wheel cylinder popped open and what was left of the shoe cut the drum in half and we had to cut the backing plate off to repair it. It was still running when a cop turned left in front of it while my wife was driving and totaled it.
The old Pontiac trophy 4 from the 60s would be a.nice choice, since some of the V8 parts can interchange such as over bored pistons, heads, and and carb
I bought a new 1964 2 door sedan with a slant 6 when I was in the 10th grade. I would have loved to have this motor in it. The slant 6 was an indestructible engine!
Very cool. Brings back memories. In about 1975 my brother in law had a 1972 Challenger with a slant six, three speed on the floor. It looked good but not much power, it would have been a whole lot more fun with this engine.
Hey Pat, Frankie really enjoying all the 6 cylinder builds you’ve done the past few years. It would be awesome to see what you guys could do with a PMD 250 OHC, aspirated, injected then boosted. Thanks again for the great videos! Wayne

Hey I saw this yesterday on tv
Those engines are good for 450 hp NA
Engine Masrer’s supercharged one and it didn’t break 300 HP. I saw a video on a NA one with an exotic 3 carb set up. It fell just short of 300. For PowerNation to get 400/500, I’m amazed. That is over 100 more than what I’ve seen. The heads are not designed to be performance. Intake and exhaust on same side really hurts flow. The slant makes it almost impossible to to have the intake on one side and the exhaust on the other. I had so much fun rebuilding my 65.
30 seconds in... I had a Dodge AT114 225 Slant 6 manual, Dana 60... I had lost my Australian Ford Falcon XA GT Coupe (Hardtop), via Hardie Ferrodo's new "asbestos free performance pads" that i was recommended to try out through my specialist suspension handling business. Lost brakes, my car, a milk truck...yes...he T.boned me as I went backwards through a T intersection at about 90kmh with no brakes. 4 wheel discs, stone ground on the axle and hubs. So, I had a spare 351 Cleveland 4MAbc cranked engine and block..... manual FMX 3k stall, Dana built with LSD and 4.88 gears. I could smoke the custom duals from a standing start, FMX auto, retreads....and snake 4 rubber marks for 50plus metres. 😊
.....now im kinda wishing I had.... lol. I did my swap in 1991. This engine is sick.... Aussies build great stuff. Americans can do it far cheaper...so its awesome to see some of our best being shown. Well done guys
I built a forged crank 225 slant six that was bored to fit Mopar 2.2 liter dished turbo pistons on 198 slant six rods. Oregon Cams reground a stock cam for a little more mid-power oomph. For the valvetrain I used Ford 2.3 Ranger valves and machined the head for Pontiac 400 springs, and did a "bowl hog" on the intake side. For carburation I used a Holley 350 CFM on a modified Super Six factory intake. Spent gases left via dual Dutra manifolds, which made it necessary to use a Dakota V-6 starter. The stock distributor had lighter springs added for more initial advance, and I used a big block timing chain. I also adopted a GM HEI ignition feeding a Ford Taurus e-coil. I had it hooked to an A833 4 speed. It made about as much power as a stock 5.2 Magnum, but it was different! And it was definitely a lot of fun making something that not everyone else had. I'm glad I got to take my dad for a ride before he passed away in 2020. He was a dyed-in-the-wool Mopar nut.
I couldn't believe what I was reading! Absolutely loved seeing this. I used the same pistons and rods in one of my builds back in the early 90s with my 66 Valiant 2dr. I used bronze bushing in the small end of the rod to float the pins for the turbo pistons. My valves were stainless replacements from Racer Walsh for a 2Liter Fords. They had the smaller diameter stems, but were a larger valve diameter and they had to be .100" longer than original Ford length. Used a Erson Flat Tappet Cam from my earlier 170ci build, yet had it reground to a roller and used 440 roller lifters. Fully ported the head. The carb was a Holley 390CFM Vacuum Secondary with 125hp nitrous plate between it and the Clifford Intake. Homemade headers using the flanges from an old Clifford set I picked up at the Daytona Swap Meet. Ran a Mallory ignition box and distributor. Built a 904 tranny with a reversed manual valve body. It still is the one engine I had the most fun building and racing with. Nobody could ever believe that it was a slant six until I opened the hood. Thanks for commenting PapiDoesIt, this brought back some great memories and motivated me to make my first youtube comment.
I love when people combine odd car parts because a ready made performance parts don't exist.
I had to read that 3 times... AMAZING!!!
Awesome how you discribed your build, I though you might have been a host on powernation! Love the build!
Very interesting build !!! Thank you for posting this. 👍👍
Aussie fan here. I love the fact your doing a tough inline 6. Especially the old leaning tower of power 225! Excellent!
Hey Paul, I remember been smoked by a Centura 4 speed & hot 245 back in the 1980's in Victoria
Did they have a slant six in Aus?
@joshfishmaster2748 Absolutely! We got Aussie built Valiants in the 60's and 70's. 225 slant, 245 and 265 inline 6, 318 V8. All good stuff!
@@pauljcampbell2997 My father put a 283 V8 in his 1968 Land Rover short-wheel base, five years before Land Rover and Range Rover did it, we also had the 360 here as well. And, Ironically The Range Rover V8 was based on a Hemi design.
@@joshfishmaster2748yes 😂
for a engine that was designed , a half century ago , this is impressive . long live the mighty slant six !
it's no Ford 300
Math is inconvenient. The slant six was put into production in 1959. Closer to 70 years since design work started. I'm in denial too.
Great engine !! i think they lived till 2007 in mexico or something , i read somewhere @@wolfhobbies
@@wolfhobbies was gonna say probably slide ruling day I was born in Aug in 57. You know someone was doing something in several departments for that, they used to drive them a few months, trying to find out everything they could. Chrysler especially, in most, don’t understand why not 7 main , but they don’t have much of problems with it
75 years ago this engine was in production
Slant 6...Bullet proof stock. Ran one 100 miles without a working water pump to get home, changed the pump and good as ever
10 miles with a rod out the side of the block, got me home. Can't say the other big Two ever came as close to saving my butt.
We had 3 darts wt over a million miles combined! We never checked oil until the lite came on!
@@davesturman1503damn
@@davesturman1503I drove an Oldsmobile 350 with spun bearings for over a week to work and back. The bottom-end would be SO hot by the time I got to work, that the motor would be seized after I shut if off when I got there, it wouldn't crank over anymore. An 8 hour shift later, she'd turn over again and run long enough to get back home. After a little over a week of this routine, the big ends of the rods wallowed out large enough so that the rod bolt nuts started scraping the inside of the oil pan. It didn't take long before they scraped a hole in the pan, and I started losing all the oil. At that point, I just put it to the floor in park, and put it out of its misery in a spectacular fashion, and scattered rods all over my driveway. That motor was a tough S.O.B. though, to be able to go thru that abuse.
I'm a big block Ford guy and this was one of the coolest most interesting builds I have watched on your show. Keep it up this was great. Really love the creative ingenuity and tech skills shown.
Ford made a big block six, unlike other makers.
You should invite some of the great Aussies over, or even take a trip down under to build a Barra! That'd be really cool to see your take on it!
Would love to see a Barra built...pump gas
Just build a vortec 4200 it's an engine you can actually get parts for were just of their viewers are
Vortec 4200 , Amerabarra!!
@@philosophicalfloridamansince when does it have more parts than a barra?
I don’t see the point in watching the build of an engine that I’ll never get to own. I’d rather see a 4200 get built.
Absolutely the best engine Chrysler ever built. Had four 225's and one 170 engines, The last was '81 Dodge truck, super six (2 bbl) 2.5" exhaust. MSD 6 / MSD coil. MSD copper plug wires. plugs gapped at .065. 22-24 MPG with O.D. 4 speed. sold with 400,000 miles to a guy in Traverse City Michigan. Last I knew it was past 500,000 miles when I lost track of him. Had to pull the head at 350,000 miles and replace number 6 exhaust valve with full clean up & valve job. Just an absolute great engine ! There is a buddy in Thawville Illinois with a Dart that has a turbo charged slant six from 30 years ago. Lots of slant six fans out there !
We had one in an old Volare Stationwagon that turned over 600,000 before the frame rusted out from under it. That engine is pretty bulletproof.
It's funny to see Frankie slowly becoming Pat's protege. Before you know it Frankie will have a pocket protector, goatee and receding hairline just like Pat.
😅
He doesn't have a receding hairline, he has an advancing forehead, on account of all the magick and engine sorcery he's trying to keep contained behind it.
If you go back about a year you will find episodes where Frankie is wearing a pocket protector

Those old Slants could be beasts. We had them down here in Oz. Much respect for Mopar Technology.
It's official. I'm old. Sat night and I'm watching an engine build.. very cool..
Ditto 😊😊
Best /6 build I have EVER seen! 500lb-ft at 3,000rpm is a good big block torque number! That's just insane.
An inline lives for torque, and the long stroke of the slant begs for that turbo, even at 2-3 psi would do wonders
Turbos equal torque - it's why ALL the big trucks use them.
I had an uncle (r.i.p.) that started built Mopar motors back in the late 60s. Back in the early 90s I drove a 71 Dodge Dart with a slant 6. One of my uncle's buddies was an eccentric guy that built up a slant 6 with a supercharger, he sold me the engine and we swapped out the drivetrain in my 71. That thing was a beast, had to be putting out 500h.p. All the street racers at the time were mostly running foxbodies with that 5.slow. it was too easy taking their money if they were stupid enough to try.
You should look up the Ford 240/300. Guys make 300HP on them naturally aspirated.
The evolution of that engine is even crazier, look up the Barra. Thousand horsepower is common on stock parts.
@@alexcorona They did a Ford 300 build.
Next time I see an old duster beside me at a light , I’ll think twice. That is some serious torque!
At 4.25” stroke it atta be
just needed some boost to truly utilize it....over 500 pound feet only running 10 psi is mental, and thats coming from a buick v8 enthusiast lmao
If Dennis Weaver had this motor in his '71 Plymouth Valiant, in 'DUEL', he would have stood a chance against the truck!
If I remember, he had a phobia of going really fast (like vertigo or something would creep in at 70+). If he could keep that in check all he would have to do is drop a gear and dissapear.
He killed that Diamond Reo in the end. The sound of the truck going over the cliff was the same sound effect when the shark in jaws got blowed up.
@@harrylister804 They have "crumple zones", or "sacrificial structure", so I guess the poor little Plymouth became a "sacrificial crumple zone"!! 🙂
(And, always carry a briefcase to jack yer gas pedal, if you find yourself in the same predicament)
There would have been no movie 😂
Absolutely "nailed it"
Aussie here. I had a stock-standard 3-speed auto 1966 VC Valiant with this engine during the 1980's and I LOVED it. I drove it back and forth between Sydney and Brisbane a lot, Broken Hill and Adelaide one time, down to Canberra & Melbourne - and fully enjoyed it every day. It didn't seem to matter that it had drum brakes, no power steering, nor air conditioning. There were quite a lot of them getting around in Sydney, and then in the 1990's they faded away, and now are a rare sight.
I’m in Mopar Heaven with this build! I have owned 5 slant six engines and know them so well! These are great engines!
@@bigboreracing356 these engines were reliable and did everything I needed them to do including being economical to run right through the two gas crisis in the 1970’s while thirsty V8 were expensive and impossible to run when gas rationing was in effect! I was able to drive and give rides to and from my high school for my Motörhead friends, with no sweat on the rationed fuel I was permitted to buy. If you don’t remember whether you could buy gas was based on the day of the week and whether your license ended on an odd or even number, and was limited in how much you could buy. With a Duster, and a 16 gallon tank, I did not max out the gallons portion of the limitation and getting 25 on the highway and 22 on the freeway sure helped as well!
I could never blow it up when I was teenager I’m in my 50s now and the fella that bought the 73 duster he still drives it around with original engine
@williamchapman2434 I had a 73 with the slant six when I was in high school. Loved taking it to car shows, and always opened the hood. Everyone else had dressed upped engines, but I got many compliments for just keeping it original
Mopar S6 power ... love them Slant 6's... I had one in a '79 Plymouth Volare' 2dr coupe... miss that car 😢
@@gabec2494 there are Chrome Valve Covers, split 3 +3 headers for dual. Exhaust, Super Six Two Barrel aluminum cast intakes and a Carter 2 Barrel to get a little extra fuel and air into those six cylinders!
First, I love Lake Speed Jr's knowledge and enthusiasm. He is an ace. Then there are plenty of comments about how much power an old engine design made, but this is the beauty of turbocharging these engines, they push the air in there and overcome some of the deficiencies while preserving some of that low end that they were known for. That is not to take away from your porting and planning. That was key as well. I particularly like the save you guys pulled to get the forged crank in the cast crank block. Good work!
Over 400hp and 500lb of torque is impressive for a leaning Tower of Power.
Go the mighty Mopower!
My pop had a 78 Plymouth Volare with the straight six. We put 238K miles on that engine and it didnt burn a drop of oil and always started up right away in the morning. Truly a great engine!!!
This engine was originally designed as a reliable do-all machine mover: cars, pick-ups, boats, sawmills, off grid electric generator, you name it. What you guys did with it is truly AWSOME. I loved my '73 Duster with its slanty-six. Chrysler should have used a good cross flow head on these right from the start. Never dreamed it could be so capable with 21 century tech.
I had a 72 Duster with a slant 6. I spun the main bearing and still drove for miles before it died completely. Imagine racing a big block and win with a slant 6 with those numbers on the dyno.
I think a hemi head based on the Toyota 2TC and 3TC could work on a slant six. The pushrods are on the passenger side of the block. The 3TC can be bored to 3.50-inch with good sized valves - although it was only a 1.8 four with 75 hp stock, but when modded can make 600 hp. The custom head could use Toyota valve train parts -there is still a T series niche aftermarket - billet heads, big valves etc.
@@timothykeith1367 That would be awesome. Your idea might just entice someone to try it.
@@timothykeith1367Just the way they built it, it's 600 hp capable, they were going sooo easy on this setup. Send that boost up to 18 psi and watch, 600+ hp or more. The internals are all top notch, and it didnt even blink at that 11lbs.
😢@@izzyplusplusplus1004 The 3TC is a 1.8 liter four. When extrapolated to a six it's 2.7 liter - about the same displacement as the 170 slant six. I'd like to see just one built. It would not be popular on street Valiants and Darts because the intake manifold is on the passenger side, but I think there is as much space as the original Corolla had. That aftermarket billet heads were created is an inspiration. A 700 hp turbocharged 3TC can break the block, block damage could also be a problem with a slant six. On the 3TC a main bearing support "girdle" is custom made. It's cool what they can do with the 80 hp economy motor.
This and the ford 300 have been the most awesome videos I have seen. I love the creativity and ingenuity that goes into these less common builds. You guys set a world record in my book, 400 hp and well over 500 ft-lbs of torque with 11 pounds of boost is wicked. I would be curious to see what it does with 15 pounds of boost. I guarantee the power numbers would be a record 😉
You can double the na hp with 1 bar of boost, if things are optimal. 15psi is slightly over 1 bar.
@cortinamk1598 1 bar is equal to atmospheric pressure at sea level which is equal to 14.7 psi 😉.
No Brasil tiramos 2000HP dos motores GM 6 cilindros 250s (obviamente carros de arrancada que usam esses motores) o motor GM 250s veio originalmente no chevrolet opala que na época era concorrente do Ford maverick que usava um v8 302 e do dodge dart/charger RT que usava um v8 318, o opala era o mais leve de todos, o opala SS tinha 171 hp contra os 200hp maverick e 215 do charger RT, o opala era mais rápido pois do pesava 1190kg

@@gabrielsimoes9068awesome
We loved being part of this build, and we are proud of your out come. Nice work!
Awesome engine, I turbocharged one back in 1978 and ran 14lbs of boost into it. It kicked so many big V8 butts. It was pretty much standard other than a Holley 350 and O-ringed head and it held up really well as long as I kept the water methanol up to it and used Super Fuel.
I was around and at Chrysler performance back in those days. Ps I think we made the head gasket leak at 16 lbs, but it didn’t fail. So much to all this.
@@4406bbldb actually I think it was my block I o-ringed, not the head. I ran it with an 18lb boost spring in the wastegate for a little while but it made me nervous for the engine :)
Dropping this into a light A-body like a square body Dart with a 5 speed would make an incredible track day car. With overdrive, an eco tune, and a sane 3:55 rear gear, mileage above 25mpg wouldn't be hard for a great track and street package.
That sounds Kick-Ass.
A 904/2200 stall would work nicely as well, they use less power than a 727 and can be built almost as tough
I'd prefer an older style pickup. But a lowered dart would be nice.
I have a 1974 Dart Custom that could use a buildout like that! It would be a grandpa sleeper for sure! Do you guys wanna sell it? Sure would love to have it or the current Slant 6 built out just like it!
Dodge Dart AKA Aussie Valiant YEAH BABY!!! -- I've had 4! Including the Stirling Moss variant!
Uncle Tony's Garage would be so proud! Awesome build guys!
This build was awesome. Never would have thought 400 H.P. on a fairly conservative 11 psi of boost. And that torque is going to light some tires.
An extremely impressive build, gentlemen. What is more impressive is that in its current configuration (11 lbs boost) it is still very street able. I have no doubt that if you want to go racing you could get more power by turning up the boost...but I got the impression that you guys were aiming to build a better, driveable, “leaning tower of power”...awesome. I think you have very successfully achieved your goal. Great work!
Those 500+ torques would be *very* fun to drive. Especially that low in the rev range. That's good stuff!
That torque curve is incredible.
You guys have absolutely killed it! Frank, Pat, and to all of you at PowerNation, Thank You! The whole year it took of planning, sourcing parts, and the convincing it took to get this project, I could only imagine. I just want to say, it has all payed off, and you guys should be proud. Not once did I skip the video, and your guest that you had for Piston Rings, and Fuel Injectors was a great choice. Whatever the vehicle choice may be, like a W250, or a Dart/Duster I'll be Looking forward to what you guys have in store for that awesome Slant!!
get the transmission guy to build a torque converter a 2500 rpm and that should be a interesting ride !

Could you imagine today's turbochargers on one of these back then? this motor would have blown minds.
Thank you for this build. Just because the average Joe can’t budget a build like this doesn’t mean that you can’t enjoy what can be done with “old technology “ when budget constraints don’t dictate what you can accomplish. I love straight six engines and I personally think that there’s a huge market for plain Jane work trucks with straight six engines tuned for torque and a minimum of high technology add-ons that are running costs through the roof for new trucks.
This could be done fairly cheaply as a DIY project...

My first car had a Slant 6 and you couldn't kill it. Those long intake runners and long stroke make torque forever.
My first carcwas also a slant 6 66 Dart. As a typical teen i abused it and it never gave me trouble.
At 16 years old in 1970, my first car was an early 1960 Valiant V200 (the birth of the Slant-Six,) which I bought for $100 that I earned as a fry cook at KFC. I fixed it up 100% with pick-a-part used, and economy new, parts, and High School Auto Shop know-how. The adventures we had in that car are too numerous to list. Later when I had a "Data "Processing" career, I was always buying cool old cars: 1958-1961 finned Cadillacs, old pickups, a Falcon convertible and Ranchero, even a Jaguar XK140. Life happened and I don't have them any more, but the car I miss the most is the '60 Valiant. Watching this video, how could I not picture my beloved Valiant found and restored better than new with this marvelous motor!? (Heavy sigh...)
Almost 1.75hp per cube out of a slant 6......just as Chrysler intended. 😂
Loved this build.
I love how excited the Total Seal guy was about hi performance piston rings. He is perfect for that job.
He is on Stapleton42 getting his dad'snascar back on the track. Super guy with tons of knowledge. Lake Speed Jr.
Now that’s a leaning tower of super power!
Very impressive work guys!
As one of your viewers, who requested this build, thank you! Freaking awesome - such a bad ass little in-line six.
But, want to see some more juice out of it.
I love it as well. Secretly I'd also like to see it with a twinscroll turbo..it's possible and more torque down low..who doesn't love that?!?
@@gorkzop ohhhhhh that would be super cool. How awesome would it be to get to 440 -460 hp and 80% torque from 2500?
@marshallwilliams4054 would be really cool. I know Saabs made peak Torque at even 1800RPM and peak HP around 550. But that was like 230HP out of a 2.0 with 11psi of boost
I figured with those manifolds, you could have small parallel twins. That is how the RB26DETT was built.
Great informative video guys. No BS, no "attitood" just build it right.
Results tell the whole story. That would be a terrific street engine in an old Mopar. Bags of cred there.
Frankie is now sportin a Pat pocket protecter with all the fixins. I really like this pair. I don't like to miss an episode. Keep up the good work guys.
I have had this same idea for about a year. I grew up with this engine and it is absolutely indestructible. Thank you very much!!
Best episode in years, love the slant six.
That is awesome. The 225 is legendary. I had a 66 Dart growing up. It never failed me.
The slant six, in many variations, had a production run of about 23 years! I had one 1963, in a Valiant. Great engine. It was known for its durability and ease to work on. It was also placed in tractors and boats. The Australian s had their own variation. For the cost to buy and operate its one of the very best.
Forklifts had them too
We had a 77 D100 with a slant 6. It was used and abused, turned into a a trash/farm truck in the mid 90's before rust finally got it. But the motor never died despite how poorly it was treated and maintained. Great choice. This along with the other inline 6 builds are by far the most interesting and cool videos on the channel.
An engine with a great pedigree! And a bulletproof bottom end. Great video guys!
Clay Milican is such a cool person! Loved seeing him on the PFI Speed channel too!
The 225 slant 6 was one of the best engines ever made!
I've been wondering for about a year now what the potential is for a nice Slant Six build with those Aussie Speed parts and a turbo.Very satisfying result! Great job guys!!!
The "Tilley VC Valiant" had a Slant with 635hp, a decade before the AussieSpeed stuff came along. Now, with those big manifolds, a better Dutra-into-turbo section, and ports like Pat got here, the limit is going to be the temperature drop the intercooler can achieve.
Even up to 90 thou over, a Slant block will handle more boost - There was one on the Aussie "MoPar Forums" back 20 years ago that was 120 thou over bored and it cracked the bores at 17psi boost.
"Potential" will be, what cost more, this build, or a new Hurricane crate motor swap :)
Had to watch again. Awesome build with incredible numbers. Thank you a million times for doing this build. ❤❤❤❤❤
Most excellent slant 6 I have seen. A few extra minutes showing details of wiring would have been really interesting, too. Thank you.
Our first decent family car was a near new AP5 Valiant back in the day. My father loved it. After 20 years it was still going strong until some octogenarian went through a Stop Sign and wiped it out. I swear he shed a tear when it went to the wreckers. Today it would be worth a mint and repaired. I send him all these RUclips vids on highly tuned slant six engines and he loves them. Hard to believe that 60 yrs after he first purchased his, it's now out of his reach to buy another.
This engine looks like so much fun, I was so close to buying a 265 Hemi to swap into a Volvo 245, but snapped up a Volvo 164 to satiate my 6 cyl desires. Yella Terra and Aussiespeed are great Aussie companies I'll continue to support.
This has to be one of the best builds you guys gave done on this show. Fantastic👌🏻
A max effort slant 6, just genius. I can see myself putting one of these in a 2 door valiant. Great work!
Love those slant 6's! Reminds me of clifford performance motto "6=8"!!
That is a wicked slant 6. That would be an awesome set up in an old willys jeep pickup. Keep up the great work guys.
I've been waiting almost 20 years for this build. My first car was a 74 Scamp with a slant six! ✊🤘👍
Guys this is truly awesome, brings back memories when I had my 71 225 Duster. and did some mods to it but never at that level that you guys are doing I guess it's because the parts were not available unless you had a 318 340 or 440 V8, so I thank you guys for doing a build like this just for the sake of possibilities of what could have been back in the day👍
Man, I wish I just had a little bit of y’all’s knowledge about Engines. I can get just about any small Engine running good Stock. But improving above Stock is out of my League. Amazing what you did with the old Slant Six. I would’ve never guessed you could get that much Horsepower and Torque from that Engine. Way to go Guys.👍👍👍👍👍
I am so impressed... Back in the 1980s I had a 1967 D200 crewcab with a 225 in it which was slow as christmas but would pull all day. Wish I still had that rust bucket. ;-)
That's awesome! I've always wanted to do something like this to a slant six. This is expensive, but they were thorough.
Those are better numbers than the six pack 440 magnum had in 1970. Well done.
Very impressive! I didn’t expect that power level. Well done!
As an Australian my Dad had one in his highly original AP5 Push Button ( gears ) Slant 6 ... 225. In the 1970's
This build is perfect . 11psi av is XCELLENT
Having worked on these engines, what you’ve done is so impressive! Can you explain how you hooked up the oil line for the turbo? For a Dyno, the oil pan works. I would suggest a baffle when placed in a car. One small turn or a hard launch and you will lose oil pressure. Once that’s gone, no bueno. What a build. Would love this in my 65 2 door post Dart. What a sleeper. You guys are awesome. ❤❤❤
Holy hell. I ran a 225 slant six back in the mid - late 80's with Clifford industries goodies and a custom Racer Brown cam. It was in my 1965 Dodge Dart and was a very consistent ET drag racer. It wasn't super quick ( 13.56 best ET @ 89 mph. ) but it would hit that number nearly dead on all night long. It sounded like a full blown stock car ( the race kind, not a stock vehicle! ) It was also my daily driver ( as it would be back then I suppose ) Good times.
13 second 6 banger is impressive but back then? Thats what you call a sleeper
Even seeing a turbo 225 today Id never guess it would make that kind of power.
Muffle that sucker down and take peoples money!
@@gordocarbo I was fortunate. My uncle was a former indycar crew chief and avid endurance racer ( Dakar et. al. ) He did all my head work and used motorcycle tricks on the valves ( back then multi angle valve jobs beyond 3 were virtually unknown. ) I was just at 11.75:1 compression as well. I used a mini-spool that was a pain in the ass on the streets, constantly chirping when I'd make left or right turns. Before the Alston boys split I had them do my rear end. 4 link with auburn gears. Ron Souza@ ADCO Transmissions handled my tranny. All this was in prep for an eventual 383 swap - which I did and that's when the trouble started ! :D My slant 6 ended up in a tractor at my ex girlfriends dads farm. I did street race my lil white beast but I was small potatoes to be honest. There were legit 9 second street cars here in Sacramento in the late 80's
This is absolutely amazing. The first engine I ever built was a /6, and while it had a couple of small tweaks (Super Six intake, 2bbl carb, hotter ignition, and a little cam,) this is just 100% mental. I could see this in an Aspen woody wagon with an 8-3/4 rear and a 5-speed absolutely blowing peoples' minds at the strip.
👍👍👍👍👍👍😀
I was in my teens when I first drove my dad's 225 slant six.
Good torque and smoothness out of the factory in a 1971 blue Dodge Dart 4 door sedan.
The only problem was they have drivablity problems in low atmospheric pressure during rainy and snowy seasons.
Mainly, it's those ancient poorly designed mechanical carburetors that use low tech vacuums assist systems ruined the drivibilty. Causing it to stall frequently during morning cold starts.
I always wondered what if those fuel systems would be improved someday would be like for the 225 cubic inch Slant Six.
This show has brought my early teen's imagination to real life .
With the much improved quality of modern day fuel delivery system, latest ignition system, plus the awesome turbo added on a custom tuned & refined engine.
It's impressive enough just normally asprirated in this show.
Back then, it would be a dream or just a nonsense.
What a great build you guys, have always loved the slant six, now im even more impressed....wow....incredible...
Those engines are damn near bullet proof. Im more a v8 guy but i gotta admit these str8 6s are str8 up stout as hell. Torque monsters. It should last a very long time tbh
I'd like to see more in-line sixes being built here.
This slant-six is a far cry from the one in my old '65 Plymouth Valiant ( Canada ) :)
Loved this! My first engine rebuild was a 225 Slant 6.
I could see a market to upgrade sleepy slant 6 models with this engine and a nice 6 speed.
Great build, I've owned many slant sixes and this just makes me smile.
By far one of the most interesting engine building episodes , bravo les gars .
You guys are knocking it out of the park lately. The boosted Chrysler 225 success following on from the unbelievable power output of the aspirated Chevrolet 400 SB from a couple of weeks back has blown my mind. 👏 🍻
This is the coolest Slant 6 build in history!
Pat, Frankie, this is too cool! I'm all about V8 power, but these inline 6 cylinder builds you guys have been doing are pretty stinking awesome! They got me thinking about what else could be built.
The 225 slant six is one of the best motors ever built in any class. I've seen them run 1/4 million miles without any lower end problems. I've also seen one run 100's of miles with the main bearings so shot that the harmonic balancer was slapping the front of the block. I've have two different cars with one in them and they were insanely dependable. And some people remember they were retired but then brought back in the 80's when Dodge needed a six cylinder for truck applications while they developed a V6 for that use.
Awesome build! Showing what a Leaning Tower of Power can really do 😎👍
Hey Pete. Love your channel. You could just put up a disclaimer at the start of your vids? I’ve been a mechanic for 30 years and I learnt in workshops like yours….learnt the right way and I learnt the way you often have to do things when in the bush. It’s the true art of engineering. I was an aircraft engineer for the last 18 years and worked on modern jet aircraft, everything you do is IAW with AMM. But I never forgot where I started and you and I both know that the shortcuts are fine if you understand them. The naysayers are always those who seem to be frustrated that they can’t work out the true art of engineering. You are a bloody good bloke and thoroughly earnt employee of the month award! Catch you in Cooktown mate…look for the Perentie without the tourist stickers. Cheers
I rebuilt a 225 with a dual intake and dual exhausts and I thought that was fancy this is next level, thanks for sharing,.
Thanks for what you guys do I know you probably do it for passion and love to work on these rebuilds but I’ve learned so much and it’s fun watching these builds as well. Your doing a lot of people favors that work from their garage
This is one of the coolest engine builds I've seen. Good stuff
Very impressed guy's! Thanks so much for putting this together for us. I can't wait to see what you two put this in and hopefully you'll make a video of it on the strip.
This is hands down the best thing I have seen in a LONG time.
Wow, what a beauty! That engine is a masterpiece! Great work guys, just amazing.
Love the episode. I grew up around these engines. Mom and Dad bought a new 64 Dart wagon when I was 9. Got driven to Minnesota and back and Alaska and back from L.A. It got handed down to me as my 2nd car after my brother abused it for several years and swapped out the original 170 for a 225, and then a 273 v8 (cam, HR, dual ex). I drove that wagon at 90mph for about 2 - 3 hrs straight one time through central CA. and got the best mpg I ever got. (273 rear end). Later I had my dads 73 225 duster at the end of it's life. I only put used oil in it after the oil light would come on for another several years, wore the brakes out till the left rear shoes were gone and the wheel cylinder popped open and what was left of the shoe cut the drum in half and we had to cut the backing plate off to repair it. It was still running when a cop turned left in front of it while my wife was driving and totaled it.
I wanna see a 4cyl build from these guys they do an amazing job I'm sure they would make a killer 4cyl
I was thinking the same thing. Like a Cleveland head on a jeep 4 pot

Be great if you could get a head without the thru holes for the head bolts/studs. Need a custom cam too.
The old Pontiac trophy 4 from the 60s would be a.nice choice, since some of the V8 parts can interchange such as over bored pistons, heads, and and carb

There special DOHC heads made for racing Model T blocks.
I bought a new 1964 2 door sedan with a slant 6 when I was in the 10th grade. I would have loved to have this motor in it. The slant 6 was an indestructible engine!
I would have loved to have a set up like this in my old Swinger or D100 truck.
Imagine if yall gave that 300 ford I6 the same amount of love. Love the oddball builds!❤❤
Nicely done, good content. I love a good inline 6 build. it would be cool to see you guys do something with the gm LL8/Vortec 4200.
Very cool.
Brings back memories.
In about 1975 my brother in law had a 1972 Challenger with a slant six, three speed on the floor. It looked good but not much power, it would have been a whole lot more fun with this engine.
Hey Pat, Frankie really enjoying all the 6 cylinder builds you’ve done the past few years. It would be awesome to see what you guys could do with a PMD 250 OHC, aspirated, injected then boosted.
Thanks again for the great videos!

Absolutely bring on the Pontiac OHC 6. Very mysterious engine.
Now that could get impressive!
That sounds like fun, but where do you get parts?
These 2 guys are talented. Very knowledgeable engine builders. Wow
Every engine you build is awesome, I only wish you could do one once a week!
