Most of our rural school buses were Bedfords just like that, what they lacked in power they certainly made up for in transmission whine - & endless window rattle if the little bits of folded card fell out : )
To be fair, that bus was probably a lot lighter than modern buses due to poor insulation, lighter structure due to a lack of safety regulations to meet, and fewer components in the engine, exhaust, and driveline.
Surprisingly if you put some of these engines into something that isn’t a steel body they’ll make you do wheelies and with a super charger you could easily see atleast the gmc 702 smacking a lot of modern cars lasting forever just like how semis without a trailer smack even turbo cars
It upsets me a bit that the Hudson Hornet engine from the 50s makes the same amount of power as my Ford 300 from 1990. Both 5L, both straight 6, but the Hudson is a 6.7:1 compression flathead and the Ford is an 8:1 compression overhead valve with fuel injection.
@@aeroflopper They recorded power with just the raw engine, no accessories that would normally be on the engine. Now we record BHP with all the stuff on so it is more representative of a engine actually in a car.
Low reving engines generally have bores that are smaller in diameter than the stroke. They are a class of engine called "Under square". Under square engines develop a lot of torque because of the long throw of the crankshaft (it's a lever). A "Square" engine has the bore and stroke nearly the same. An "Over square" engine has a larger bore over the stroke. Over square engines are designed for high reving applications like racing motor cycles. They deveop torque at the wheels by gearing down through the transmission and differential.
length of the cylinder stroke mostly affects how fast it can rev. There are some tiny motorbike engines that have very small strokes and an under square cylinder design that can rev over 10k rpm. A car engine with a slight undersquare bore to stroke ratio can rev around 6000-7000 rpm A marine engine with a bore to stroke ratio of around 0.45 will rev around 100rpm. A car engine with the same bore to stroke ratio would rev around 3000 rpm. Few things to know: the length of the stroke mostly affects how much TORQUE an engine produces, the bore affects how much peak air can get into the cylinder which is the reason why oversquare engines produce more peak hp, but undersquare cylinders generally produce more low end horsepower than oversquare cylinders which is the reason why that underpowered bus (in today’s standards) is somewhat driveable.
Back in my family’s history, my Dad ran a small Mom&Sons trucking company that was started by my Grandfather. By the late 70’s after I was Honorably Discharged from The U.S.Army, I went to work driving trucks. But the day I turned 16, Dad had me working in the garage, washing the refer trucks and learning to service them. That was a small 10 unit fleet, 2, 65/66 R Model Mack’s, with 26’ refer bodies and 150hp Scania straight six diesels with twin sticks. Plus 8, GMC Straight refer body trucks, from a fleet of 10, 6500-9500 series 6 wheelers, all with the big block V6 cyl GMC gas powered engines, from 2, 305 ci to 6, 345 ci to 2, 401 ci. That all had 5 speed low hole gearbox’s, the two bigger 9500’s, had the 401, with a two speed rear axle. All ran down the road at 68-72 mph, at 3,200-3,400 governed rpm’s. That all ran great for just about 160,000 hard heavy miles, then was rebuilt in house by Dads mechanic, named Mort, who taught me everything I know about wrenching. These engines would then go on to last another 120,000 miles each after his rebuilds. All while burning no oil, but LOTS of gas! Like 3 to 6 mpg, between the truck and refer units drawing gas from at least two 40 gal tanks, for local delivery work. I also remember after The company grew up to need tractor trailers, they had bought out a local company that went under. We got 4 old gas White Mustangs for yard horse work and delivery to a local market chain wear house. One I bought with my cousin to fix up for truck shows was an old 1964 GMC tandem axle tractor that had one of those 701 V12’s, hooked to a 6 speed low hole, with posi rears, that was as used to pull dump trailers in a pit and local work! Top speed was only 57 mph, but man could it pull! Pull a 48,000 lbs load of canned goods as well as a 200 Cummins with a 10 speed Roadranger! Just not as fast top speed! But leave it going through the gears! Great yard plow rig also with a 10,000 lbs concrete block on the fifth wheel, an a huge 10’ angle plow!
Yeah, we had an old 8N on our family farm from the ‘50s before my dad and uncles/aunts were born all the way til like 10 years ago. At some point, someone put a flathead V8 in it, which was rebuilt a couple times, and of course various hydraulics and such had been modified and repaired over the years, but it still ran great when we sold it and was always my favorite for moving round bales and bush-hogging. Great tractor, very maneuverable and light enough not to tear the ground up too badly, plenty of power, looked and sounded wonderful. It started to have some transmission problems and it was sold to a guy that wanted to do a show restoration on it.
@@The_sinner_Jim_Whitney That is amazing. I’d love to have an 8N as a shoe piece and to restore. I have a LS225he and absolutely love it for my needs. Digging with the backhoe moving large trees and box blading my property as I develop it more. I just hit 170 hrs on the meter this last weekend moving 2-1/2 feet of snow.
@@Sackmatters If I knew more about tractors or had the proper place to fix it up, I would’ve taken it and done so. As it stands, I don’t have the room or knowledge, so it went to a better home than I could’ve given it. Fantastic tractor, though. Now we have a 65-hp 4WD John Deere (dunno the model number, it’s about five years old) with heat, AC, and a cab and a hoe and loader bucket for it and an ‘80 or so Deutz 4WD diesel that’s probably around 40-45 hp if I were to guess, along with a midsize Bobcat. They get anything done we need them to. We also still have a HUGE 1937 Case that will start, run, and drive but never gets used. It was historically the haywagon tractor for our square bales of horse hay, but it’s been retired for a long while, probably 20 years. It’ll probably go soon, but it was my late grandfather’s first big purchase (even before the farm, at that time he was leasing land for corn, tobacco, and Hereford cattle) and I hope one of us will restore it one day.
@@The_sinner_Jim_Whitney That is so neat. I wish I could buy a tractor with a heated cab for my snow removal and winter projects. That’d be a dream come true. What size bucket do you use on the Deere? The backhoe that is. I love using bobcats and skid steers in general they can move so much for their compact size.
@@Sackmatters My uncle is the one who does most of the daily stuff and owns the equipment, so I don’t know exactly. I know he has an 8” and a 24” bucket, I assume the volume of them is sized to the tractor. Same with the loader, appears to be of roughly the same size as all the small-ish backhoe loader buckets I deal with on jobsites (I’m an IBEW electrician), but I couldn’t say what size it actually is beyond probably the factory-recommended size for a 65-horse diesel John Deere. Yeah, the Bobcat is awesome. It makes scraping driveways, filling holes and trenches, even moving bales or logs take like half the time it normally would.
I had a Buick straight 8 from 1953. The smoothness & intake drone are something that lives with you forever. I got it to 108 MPH on the speedo, which was amazing for a 1953 automobile.

Horsepower = Torque × speed / 5252 . You make HP by having a lot of torque or a lot of speed (rpm) or some combination of both. If you can have a large displacement engine you often have more torque because its easier to make reliable (like a tracker or a truck). But if your limited on displacement or want to save weight you have lower torque but make up for it by revving higher.
I guess the lowest-revving engines ever would’ve been the big two-stroke singles like in the Lanz Bulldog tractor and some other applications, they could like oscillate and run at literally 0 rpm.
2 stroke pile driver is no more that about 60 cycles per minute. I say cycles because there is no crank shaft but it is powered by diesel detonation. Er well that's not gas I guesd
That two-stroke "hot bulb" engine is fascinating - have you seen the video with the guy idling that tractor (at 0 rpm) in gear? The tractor constantly hops back and forth with each piston stroke! See 02:34 here: th-cam.com/video/pYeEotP_c3M/w-d-xo.html
Thanks for these videos - they are informative without silly graphics and voiceovers. The "100% content" format is much appreciated. I don't know how popular it might be - but - it would be interesting to see a video on old farm tractor engines starting back at the beginning of the last century. Some of them were over 20L with one or two cylinders...!
7:25 Oh my! I think we have one of these sitting up on the hill here at our old farm! My Grandpa tells me that he remembers when he was a kid the reverse gear was too fast which made it hard to drive and park
we have one at home, which my dad and my grandfather restored together the last few years and it kinda is. When you want to attach something behind it, you have to release the clutch just a little bit, otherwise it's going too fast backwards
Don't forget about the Lanz Bulldog engine with a Max RPM of 1000. At idle the engines would be running at 0 RPM. The internals would just be oscillating back and forth but not rotating the crankshaft a complete revolution. The hot bulb engine could use any fuel that was burnable including gas. I'd love to see one of these motors in action.
Another fine episode on engines of which you can count powerstrokes and see the valve rockers operating. That Continental Sherman tank engine sounds so good.
I put many hours of riding time on one of those 8N Ford tractors.😉 Everything from mowing to plowing snow, they did it all! Maybe not as fast as some more modern tractors, but they were easy to work on when necessary, and they were extremely reliable!😁
Odd cylinders always sound so good, raggedy starting radials, the best. Also, those old kerosene burning tractors pulling a heavy sled is amazing too. In the states the Rumley Oil Pull was a similar tractor, only a two cylinder. Great vid man, you have covered so much internal combustion ground, keep up the good work.
In the words of Carroll Shelby “Horsepower sells cars, torque wins races.” That's why I like diesels, though modern turbo diesels give you torque and power.
You do a good show. I'm stuck on older farm engines building them the way you would build a high proformance car engine. I like to see what you can get out of it.
Always amuses me to see these old engines. How they manage to use so much steel to turn so much fuel into such little power. The progress made is fantastic.
There is an old fire truck in Oakland Park, Florida that has that 702 V12. GM built a prototype of this engine with 956 cubic inches, but never put it into production. Great video!
My grandfather bought a Ford 8N in 1939. It was used on the farm to this day. My cousin owns it now and it hauls feed to hoppers in the feed lot. Starts even when it is -40f.
Continental had some big slow-turning engines also. I once drove a 20 ton crane on a military IHC chassis (M-62) with a Continental R-6602 in-line six that had fuel mileage that could be measured in gallons per MILE! They only had about 190 hp. from 602 cu.in. of displacement, but the torque was probably in excess of 900 ft. lbs. They generally had 2 monster 2 bbl. carbs, and redline was around 1900 rpm.😉
International Harvester built an engines for their trucks like the R190 which was a very popular seller in the 1960's and the engine type have been around is the RD 450. The engine made 202 hp @3000 rpm and 422 ft/lbs of torque at 1600 rpm's if you can believe that. Thanks for making this video.
A very popular low revving gasoline engine that I think is a notable mentions is the 4 cylinder air cooled boxer engine used in the VW bug and early porsche. If I remember right it redlines around 3500/4000 rpm
I operated one of those Ford N series tractors for my dad in the '50s and '60s. They are highly prized to this day, and thousands are still in daily use.
I’m an old guy and Visio Racer is the first TH-cam channel I subscribed to. He’d been making them for a while because the first one I watched had a voice over. Anyway, keep the great videos coming!
The 702 V12 (often called me split 6) is interesting. I occasionally rode in a school bus that had one. The church that had it ended up junking it because it needed a tune up, and they tried giving it the tune up, but couldn't figure out how it worked. It never ran again. At the time, had I known that a split 6 wasn't a 6 cylinder, I would have went to the junkyard to get it. When I was growing up, I had seen some of them in GMC semi-tractors. I have also seen Cadillac 472 engines put in semi-tractors. You should do another video on low revving gas engines. There's the W.O. Bentley 8L. 6 cylinder. The Hall Scott 6 cylinder. And I know there's a few more that aren't coming to mind right now. Have fun.
When i was in School in the 1960's our school busses were all O series Bedford's. The whining gearbox bought back a lot of memories ,especially cold mornings riding in an unheated slow bus.
I don't know where you come up with all these cool engine. But keep up the good work. This was interesting because it was low rpm and OMG where they low...
The Hudson 308 could could also produce 160 hp with just the Twin-H set up alone as well. It runs pretty good on modern gas too with the Chromium and nickel alloy block, no premium or lead needed.
Another super show. I must be an engineophile. I love them. Anything on old (or new) chinese engines? Designed so carefully now that the whole world is using some of their features.
But it's the same lump and gearbox that powered the WWII Bedford QL 3 ton trucks, all 52,247 of them, the back bone of British army transport during WWII in various body styles.
Possibly one of the longest production engines is the John Deere horizontal two cylinder engines that had a governed 975 load speed and a 1075 rpm fast idle which would idle down to under 200 for maneuvering. With the proper carburetor it would run nearly any fuel produced.
The Lycoming O-360 is about the most common general aviation engine in the most common aircraft in the world; The Cessa 172. The Lycoming 360 family of engines are gasoline powered, horizontally opposed four cylinders with a displacement of 5.9 liters, 180HP and have a maximum operational RPM of around 2700. The Lycoming 360 family of engines have been in general aviation use since the early 1950s.
Me and my grandfather had a Ford 8N tractor with the flathead 4 cyl. It was very low revving with a long stroke. You could get it loaded really hard at full throttle and it would sound like it was only turning about 200 to 400 rpm at full throttle.
On my father-in-law's ranch here in Texas, there is an old ranch truck (1976 or 77 Dodge) with a 225 cid slant-6 motor. That one is missing from your video, as those engines were in everything it seems.
About ZIL-130 and ZIL-131 engines, they was almost identical, 131 was just army variant, only diffs was armoured fuel and electrical wiring, oilpan was turned backwards to fit 4WD system.
the hudson hornet sounds very similar to a 90s era ford falcon straight 6. they have a smaller displacement at 4.0L though. still a very cool engine none the less
That Aultman & Taylor engine looks like it was fitted in what was originally a steam tractor design - the "radiator" is just the front section of the fire-tube boiler, with fans pulling air through the old fire tubes. 9:30 Love that little model OHC four-cylinder engine on the table behind you, have you done a video on it yet?
During the 60's & 70's thousands of Hudson Hornets were destroyed on circle tracks, Saugas, California racetrack was one of them. That (8)N Series tractor still used throughout the Central Valley of California and probably all of USA. They go forever! ^..^~~
Great Video, as always! Maybe you can do one about opposed piston engines? They weres used in planes, stationary engines, trucks and tractors by brands like Junkers, CLM, MAP. But even today, there's a brand in the states which uses them. It's called Achates.
The Sherman at 7:15 is a M4A4 though and should have the Chrysler A57 Multibank, they are rare and maybe has been repowered with the common Wright R-975, sounds like a Multibank though. Easy ID for the M4A4, it had to be lengthened to get the A-57 in there and so has noticeably bigger gaps between the bogie assemblies and roadwheel pairs.
Lycoming IO-540. 300HP @ 2700RPM. IO-540 series are 540in³, six cylinder, direct drive, horizontally opposed, air cooled engines running on 100LL fuel.
A BUS with 73 HP and 126 Lb-ft torque? Yikes! I bet the riders were often late when there was a gentle headwind.
Most of our rural school buses were Bedfords just like that, what they lacked in power they certainly made up for in transmission whine - & endless window rattle if the little bits of folded card fell out : )
To be fair, that bus was probably a lot lighter than modern buses due to poor insulation, lighter structure due to a lack of safety regulations to meet, and fewer components in the engine, exhaust, and driveline.
Its got the charm.
Chill ride bus:)
73 horsepower back then for pre war is actually pretty insane.
These engines don't go fast, but they go very, very far
Agree, but why there is no flat head engine with forced induction? As we know the problem of flat head is small air suction at high rpm. But why?
Durability 100

great explanation!!
One of the highest torque engines of the muscle car era was a 455 Buick. With a 4.3125" bore and a 3.9" stroke
Thanks for the technical explanation,this is good to know.
length of the cylinder stroke mostly affects how fast it can rev. There are some tiny motorbike engines that have very small strokes and an under square cylinder design that can rev over 10k rpm.
A car engine with a slight undersquare bore to stroke ratio can rev around 6000-7000 rpm
A marine engine with a bore to stroke ratio of around 0.45 will rev around 100rpm. A car engine with the same bore to stroke ratio would rev around 3000 rpm.
Few things to know:
the length of the stroke mostly affects how much TORQUE an engine produces, the bore affects how much peak air can get into the cylinder which is the reason why oversquare engines produce more peak hp, but undersquare cylinders generally produce more low end horsepower than oversquare cylinders which is the reason why that underpowered bus (in today’s standards) is somewhat driveable.

Another fine episode on engines of which you can count powerstrokes and see the valve rockers operating.
That Continental Sherman tank engine sounds so good.
I put many hours of riding time on one of those 8N Ford tractors.😉 Everything from mowing to plowing snow, they did it all! Maybe not as fast as some more modern tractors, but they were easy to work on when necessary, and they were extremely reliable!😁
The Valeo starter in my Saturn has more torque than the engine.
2100rpm ttv warrior !
Got a sudden desire to play Mudrunner after hearing that Zil, those logs wont deliver themselves!
Gotta try out snowrunner!
Snowrunner is such good game.
@@DrunkenVtec Mudrunner is better. Snowrunner doesn't even have these trucks.
That GMC twin six V-12 was used in the city c.o.e. made into fire engines. Some were tractor trailer ladder trucks, or pumper units.
Odd cylinders always sound so good, raggedy starting radials, the best. Also, those old kerosene burning tractors pulling a heavy sled is amazing too. In the states the Rumley Oil Pull was a similar tractor, only a two cylinder. Great vid man, you have covered so much internal combustion ground, keep up the good work.
In the words of Carroll Shelby “Horsepower sells cars, torque wins races.”
That's why I like diesels, though modern turbo diesels give you torque and power.
@sw4gr1d thank you, nobody understands that diesel engines feel like theyre faster because they make 90% of their hp at 1500 rpm lol
One of my favorite car documentaries to watch on TH-cam thank you I love your content 👍
You do a good show. I'm stuck on older farm engines building them the way you would build a high proformance car engine. I like to see what you can get out of it.
So rpm installed gauge x-too by ligier ?
Another well-researched and engaging collection, VisioRacer - thank you.
Glad you like it, thanks!
ZiL-130 - V8 6.0
Truck ZiL-131 fitted with engine ZiL-131 (V8 6.0), and truck Ural-375 (and buses LiAZ-677, LAZ-699R) fitted with engine ZiL-375 (V8 7.0)
Always amuses me to see these old engines. How they manage to use so much steel to turn so much fuel into such little power.
The progress made is fantastic.
There is an old fire truck in Oakland Park, Florida that has that 702 V12. GM built a prototype of this engine with 956 cubic inches, but never put it into production.
Great video!
I'm guessing that 956 prototype would have been related to the 478 V6?
@@niia.3642 Yes.
My grandfather bought a Ford 8N in 1939. It was used on the farm to this day. My cousin owns it now and it hauls feed to hoppers in the feed lot. Starts even when it is -40f.
I love seeing those old engines.
Continental had some big slow-turning engines also. I once drove a 20 ton crane on a military IHC chassis (M-62) with a Continental R-6602 in-line six that had fuel mileage that could be measured in gallons per MILE! They only had about 190 hp. from 602 cu.in. of displacement, but the torque was probably in excess of 900 ft. lbs. They generally had 2 monster 2 bbl. carbs, and redline was around 1900 rpm.😉
You could have easily started with race cars from the early 1900's like "The beast of Turin" with its 28 lt engine with a red line of 1900 rpm
International Harvester built an engines for their trucks like the R190 which was a very popular seller in the 1960's and the engine type have been around is the RD 450. The engine made 202 hp @3000 rpm and 422 ft/lbs of torque at 1600 rpm's if you can believe that. Thanks for making this video.
A very popular low revving gasoline engine that I think is a notable mentions is the 4 cylinder air cooled boxer engine used in the VW bug and early porsche. If I remember right it redlines around 3500/4000 rpm
I operated one of those Ford N series tractors for my dad in the '50s and '60s. They are highly prized to this day, and thousands are still in daily use.
I’m an old guy and Visio Racer is the first TH-cam channel I subscribed to. He’d been making them for a while because the first one I watched had a voice over. Anyway, keep the great videos coming!
Thank you, sir! I appreciate it very much
A shocking number of Ford n-series are still running and doing work to this day. My 8n is one of them.

If you have an overrun clutch and proper shear pins on the shaft you should be ok.
The 702 V12 (often called me split 6) is interesting. I occasionally rode in a school bus that had one. The church that had it ended up junking it because it needed a tune up, and they tried giving it the tune up, but couldn't figure out how it worked. It never ran again.
At the time, had I known that a split 6 wasn't a 6 cylinder, I would have went to the junkyard to get it. When I was growing up, I had seen some of them in GMC semi-tractors. I have also seen Cadillac 472 engines put in semi-tractors.
You should do another video on low revving gas engines. There's the W.O. Bentley 8L. 6 cylinder. The Hall Scott 6 cylinder. And I know there's a few more that aren't coming to mind right now.
Have fun.
When i was in School in the 1960's our school busses were all O series Bedford's. The whining gearbox bought back a lot of memories ,especially cold mornings riding in an unheated slow bus.
one more thing GULDNER G 75 SET 2150RPM
Good onya Visio. I haven`t missed a video in years
In my town the local diminutive uses the ZIL as a milk transporter and every time it pases by you can smell the gas from it
Your great vids are getting better every time. Many thanks & Blessings for your awsome work!!..
🤗🙏🙏🙏
My Ford 300cubic inch straight 6 was said to have peak torque of 295ftlbs at 1800 rpm. Never went much past 3000rpm
You forgot about the 'beast of turin'. Fiat S76
I like your content but your narration is why I subscribed. Good to see you are comfortable being in front of the camera.
Thank you!
A Traction Engine with a petrol engine, amazing! Thanks for another great video.
Nice vid bro interesting these engines also your English is getting better and more clearer I’m proud of you great vid
I don't know where you get your ideas for vids but keep them coming!
It comes naturally, hehe. Thanks
I've always wanted to build one of those gmc 702s
As usual, excellent video. We share the same fascinations with engines and vehicles...
Yes finally, I get to see that GM V12 with the heads off. Thank you VisioRacer.😁👍💯💯💯🔧
I don't know where you come up with all these cool engine. But keep up the good work. This was interesting because it was low rpm and OMG where they low...
The Hudson 308 could could also produce 160 hp with just the Twin-H set up alone as well. It runs pretty good on modern gas too with the Chromium and nickel alloy block, no premium or lead needed.
Take a look at marine application engines. These are low rev-ing. And some pretty old interesting stuff. Like the old Dutch brand Werkspoor. Greetings
After 4+ years of watching you, I feel like I have a friend over seas that teaches me about engines lol
Hehe, pleased to hear this
Man, these _Spintires_ graphics are getting *awesome*
Another super show. I must be an engineophile. I love them. Anything on old (or new) chinese engines? Designed so carefully now that the whole world is using some of their features.
Yeah, the 702 GMC was disassembled and rebuilt just one day by my father during training. Gasoline was cheaper than diesel back then.
Your vids are usually surprising, and always fascinating!! Thanks for posting.
My man, I love your channel so much! Nice work.
Thanks!
That Bedford sounds like it's gonna blow up
But it's the same lump and gearbox that powered the WWII Bedford QL 3 ton trucks, all 52,247 of them, the back bone of British army transport during WWII in various body styles.
Love those old Ford tractors!! Very cool and simple machines.
3:08 The bore & stroke of that engine is 3-3/8" x 4" (85.725 x 101.6). Compression ratio 6.22:1. From a tech manual I found online.
I could not find it anywhere. Thanks!
Possibly one of the longest production engines is the John Deere horizontal two cylinder engines that had a governed 975 load speed and a 1075 rpm fast idle which would idle down to under 200 for maneuvering. With the proper carburetor it would run nearly any fuel produced.
The Lycoming O-360 is about the most common general aviation engine in the most common aircraft in the world; The Cessa 172. The Lycoming 360 family of engines are gasoline powered, horizontally opposed four cylinders with a displacement of 5.9 liters, 180HP and have a maximum operational RPM of around 2700. The Lycoming 360 family of engines have been in general aviation use since the early 1950s.
I like your style and choice of content, keep up the good work bro!
Me and my grandfather had a Ford 8N tractor with the flathead 4 cyl. It was very low revving with a long stroke. You could get it loaded really hard at full throttle and it would sound like it was only turning about 200 to 400 rpm at full throttle.
Wao nice to see you man i was just listen your sound from long time
Great video, thanks
I thank you for stopping by and commenting!
On my father-in-law's ranch here in Texas, there is an old ranch truck (1976 or 77 Dodge) with a 225 cid slant-6 motor. That one is missing from your video, as those engines were in everything it seems.
I love these videos! You always find the weird and wonderful.
Thanks!
The 53 Hudson Hornet with Twin H power, (twin carbs), made 160 Horsepower and 275 LBS FT of torque, and the 54 - 55 made 170 horses, the 56 made 175.
About ZIL-130 and ZIL-131 engines, they was almost identical, 131 was just army variant, only diffs was armoured fuel and electrical wiring, oilpan was turned backwards to fit 4WD system.
Awesome video, can't wait for the next one mate.
Hudson hornet 308 flathead L6 lasted until 1956 (Hudson merged with Nash in late 1954 to create AMC, but kept the badge name until the end of 1957).
And with twin carbs, (Twin H Power in Hudsonese), made 160 horsepower in 52 - 53, 170 in 54 - 55, and 175 in 56.
‘This engine requires 454 liters of coolant’ wtf 😂😂😂
A video dedicated to the Honda RC series would be interesting! They have all kinds of crazy engine layouts and setups.
That is a great idea, thanks!
@@VisioRacer No no, thank you for all the cool videos 😁.
3:33 Some say that school bus took a wrong turn 60 years ago and is still lost.
the hudson hornet sounds very similar to a 90s era ford falcon straight 6. they have a smaller displacement at 4.0L though. still a very cool engine none the less
Very interesting, thanks again
Thank you!
Loves these videos man you do a great job!
Woooow! cool engines
😀 Thanks 😁
That Aultman & Taylor engine looks like it was fitted in what was originally a steam tractor design - the "radiator" is just the front section of the fire-tube boiler, with fans pulling air through the old fire tubes.
9:30 Love that little model OHC four-cylinder engine on the table behind you, have you done a video on it yet?
i love the hudson hornet sound
the 109 always sounds so cool
During the 60's & 70's thousands of Hudson Hornets were destroyed on circle tracks, Saugas, California racetrack was one of them. That (8)N Series tractor still used throughout the Central Valley of California and probably all of USA. They go forever!
^..^~~
Sad to not see the 10hp, 24.1 CUI, single cylinder, 3600rpm, monster of a go-kart, 1962-65 Cub Cadet 100/ Kohler K241AS.
It's a miniature tractor...
Great Video, as always! Maybe you can do one about opposed piston engines? They weres used in planes, stationary engines, trucks and tractors by brands like Junkers, CLM, MAP. But even today, there's a brand in the states which uses them. It's called Achates.
Ah the good ol zil 130. One of the coolest little trucks ever made
i really love your video very interesting, and i learned alot thank you very much sir !👍😃
The engine of the british Mark IV tank of ww1 was petrol and made peak hp at 1000 rpm, doubt theres any sound footage of it though
Love these videos 😁 Keep it up!
I have enjoyed all of your content.
The Sherman at 7:15 is a M4A4 though and should have the Chrysler A57 Multibank, they are rare and maybe has been repowered with the common Wright R-975, sounds like a Multibank though. Easy ID for the M4A4, it had to be lengthened to get the A-57 in there and so has noticeably bigger gaps between the bogie assemblies and roadwheel pairs.
Lycoming IO-540. 300HP @ 2700RPM.
IO-540 series are 540in³, six cylinder, direct drive, horizontally opposed, air cooled engines running on 100LL fuel.
Those Dalimers make the best startup whines
