Music. I used to fall asleep listening to a fleet of Euclid mining trucks, each with two 6 71's side by side, crawling out of the pit at a local iron mine.
I never knew your road was as steep as it is, but good golly Miss Molly, that 6-71 is like music to my ears. There is only one thing that beats it. It is the sound of an 8-71 in a Scenicruiser going up a grade with a full load of passengers at 60mph.
Every night around 10-11pm I would listen to a Western Maryland coal train coming from Pikesville to Owings Mills Md up a grade.The locos were EMD 2 stroke Detroits.This was 1955-65.Unforgettable sounds
When I was a kid I would visit my uncle every summer and he was a log hauler and I rode in the truck with him numerous times. He had a Mack E9 V8 superliner with the twin stick quadraplex transmission that was probably turned up well over 700hp. I remember one trip we were on highway 108 climbing the Sonora Pass loaded and the sound coming from that V8 was simply amazing and to this day I haven't heard anything close to it.
I remember that sound. Step dad had a small trucking company with all GMÇ cracker box cab overs with 6 cylinder Detroit's. I was the shops parts cleaner on weekends when trucks were in for maintenance or repair work. Learned how easy they were to disassemble and put back together. Haven't been around them in over 50 yrs. I didn't go into the trucking industrie like some of my siblings did. Still love that sound.
My first assigned concrete truck had a Detroit in it mounted in a '79 Ford cab with an eight yard smith mixer. The engine was so clapped out when I was assigned to it that if you had to stop in the bottom of a hill then you'd never get it up to speed. The starter would quit working once the engine was up to operating temperature and if you stalled it the engine would start running backwards. And yes,it made that distinct sound.
This sound puts a lump in my throat and mists my old eyeballs because it makes me time travel back to 1969 when I was the engineman/gunner on a Navy riverboat on the Mekong river, Vietnam. Imagine 20 or 30 of these musical smoking beasts lighting off at the same time on a misty morning start to an event filled day on that mighty brown snake of a river. Change the oil, keep them cool, drain the water from the fuel tanks every day and they Never failed me. The only time I saw a 671 die was from being shot through the block by an enemy B-40 RPG. Thanks for this ride on the 'Wayback' machine my man........
A friend of mine and I took the muffler off a 671 in a cracker box GMC,put the muffler back on after a 5 mile test,later drove a 8v71 turbo charged with straight pipes could handle that,awesome sound,wish I had known as much about those ole two strokes then as I've learned watching this channel
I remember that sound when I was a kid. The fire station up the road a mile or so up the road. We could hear the trucks going out on a call late at nigh when it was quite. We're talking the early 60's! Great sound.
Nothing like those 6-71 DDs. Super sound. Remember that sound well from when I was a kid. All our local buses had them. 8-71s aren't too shabby either.
In the late 70's I drove a college choir around the southeast US in a 4104. One of my memorable trips involved a mountain tunnel (I think in WV, not sure). As I approached the tunnel entrance, I pulled back my little driver's window and slowed down to about idle speed in second gear and slowly increased the speed as I would through the gears. Music to my ears!
I started building a hot rod semi to use as a totorhome. I grew up early in trucks before dad started driving busses. We still trucked and had a fleet of busses too. But i remembered a sound from being young but i had forgotten what it was. I set out to find that sound. I then searched for a 12v71 for that project but decided to go to an 8V71 after realizing the mileage difference per mile! That was about 5 years ago. Now i have 3 DDs. That 8V. A 6v92. And my 6-71 in my Flxible bus! Its a sound nothing else can recreate!
Man Lenny sounds great. Probably one of the best sounding 6-71’s in active services. Nice to see you do an informational video like this. Does good for a lot of the newer viewers.
Ah, the sound of music. Once, on a trip from Carson City to Reno, in the 70’s, my 6-71 went around 2 Eagle 01 models. They were in second gear climbing Lakeview Hill. I had a 4509 x-Key System bus that was at least 10 years older. If you pay attention to the maintenance, they can last forever. (Except in California, due to rule making)
I have four of the Detroit two strokes to get my fix. A 6-71, an 8V71 in my bus, an 8V92T at 450 HP in my big snow blower and a spare 8V71T at 405HP out of a self propelled Howitzer. (spare engine for the bus)
The bus is clearly in great shape. I will never understand the 20th century person's fascination with the noise of propulsion, however. The silence of the modern EV is bliss. The closer an ICE comes to that standard, the better, like the v8 boats of the 60's and 70's.
As a little kid in New Zealand i knew the 2 stroke diesel sounds from a local limestone quarry who had a fleet of english commer TS3 powered trucks . For a tiny engine,they produced a lot of power . Google the TS3 for a look at a fascinating powerplant 😊
How is Lennys interior fit out coming along. He certainly is beautiful now that he's sporting a new paint job he's gotta be one of the best silversides around.
Brilliant sound ! 671 Helped win the war back in the day , very popular , such was demand you couldn't even buy one privately you had to be millarty or government office , really top design ahead of it's time , only immisions being multifuel killed the two strokes,
Have you considered some kind of timing system from the traffic signal to some point over the crest of the hill? Perhaps even tying it into a trail camera to gets photos as the vehicles begin their run. I'm not as good at details on this sort of thing as you are but the results would be interesting.
It's amazing there's enough time for combustion and transfer of energy before the next revolution. I'm guessing there's quite a bit still happening in the exhaust based on the noise 😂
I drove a 671 in a fire truck for years. You never forget that sound.
Music. I used to fall asleep listening to a fleet of Euclid mining trucks, each with two 6 71's side by side, crawling out of the pit at a local iron mine.
Hopefully you weren't driving one of them at the time 😁
I drove the Euclid in my early days in the rock quarries and they sounded great and had plenty of power to haul rock.
Those were the days
Scott it has got to be the best symphony ever produced by a commercial vehicle I love it
Detroit. Turning deisel fuel into music since 1938
Nothing sounds better than those old Detroit Diesel 2 strokes, especially the 6-71's!
That fresh paint job on Lenny looks fantastic.

Lenny’s exhaust note is a symphony of perfection! What a hum!❤😎👍
Thanks for that. Old school power. The old masters sure knew how to build. Thanks to you for keeping them running.
When the old bus sounds more formidable and solid then any of contemporary racing engines 😀
Nothing like the awesome sound of a 6/71 Detroit Diesel. Thanks for sharing, Scott!

Sure do miss the sound of those Detroits
Thanks(no thanks) EPA😢
Thank you Scott for keeping these beautiful Detroits running!
I remember when I was young and to used to get goosebumps hearing the sound of those engines especially when they shifted gears . What a sound 😊
And that ladies & gentlemen is how a properly tuned 6-71 sounds! #scottknowsdetroits
That sound is in fact music to me also. So many harmonics, I just have always been fascinated by that sound!
A friend of mine and I took the muffler off a 671 in a cracker box GMC,put the muffler back on after a 5 mile test,later drove a 8v71 turbo charged with straight pipes could handle that,awesome sound,wish I had known as much about those ole two strokes then as I've learned watching this channel
That was a beautiful sound! Thank you for bringing back memories.
Awesome sound! It reminds me of the times I rode the Greyhound. More 60's & 70's era
I bet Phil tuned in for this post. Sounds so good.
Sounds so sweet. Its like 'oh, honey, Im home'

You did a great job on Lennie. Great vintage bus.👍🏻👍🏻👍🏻
Had one in a 38 RB face shovel years ago, superb engine.. And that sound!!!

The old beast cracks along nicely & it dont even smoke

You've reminded me to watch some flxible buses! My dad had one with a 8v-71 !
Man Lenny sounds great. Probably one of the best sounding 6-71’s in active services. Nice to see you do an informational video like this. Does good for a lot of the newer viewers.
Damn...what hill..sounds really great. Lenny's lookin good too.
✌️❤️😁
Lenny is sounding mighty fine. He's ready to run with the "big dogs"!
Great sound! Worked around a lot of logging equipment in Montana running Detroits.
Ah, the sound of music. Once, on a trip from Carson City to Reno, in the 70’s, my 6-71 went around 2 Eagle 01 models. They were in second gear climbing Lakeview Hill.

Lenny sounds great! It was sort of a duh to me moment when I realized a 2 stroke sounded like it was reving twice as fast as it should. . .
Lenny is just wonderful now - I’m so pleased you were able to make him so nice
Awesome!! Thanks for the info about the cylinder size, didn’t realize that. 👍
I grinned the whole time! That's music to my ears!! Thanks Scott!
I remember that sound from many years ago I recognize it mid 70s early 80s
Deep Growl , music to the Ears 😎, thank You Scott for sharing that👍🏼👍🏼.
Love the sound of that motor.
Lenny looks and sounds great.
Lenny is a well
Tuned running machine. Thanks for posting video. Music to my ears
Bravo! Great vid, perfect camera location for that wonderful engine.
YES! loved that sound! Thanks for making that video.
Lenny has a throaty deep roar. Look out , here he I come! I would love to hear Lenny going through I-77 on the West Virginia turnpike.
I have four of the Detroit two strokes to get my fix. A 6-71, an 8V71 in my bus, an 8V92T at 450 HP in my big snow blower and a spare 8V71T at 405HP out of a self propelled Howitzer. (spare engine for the bus)
That sound is what lead me to you years ago when you were traveling with tools.
We had a old Terex haul truck that had a 12v71 and it was loud but sounded great hauling sand and rock for a asphalt plant
HI guys from Victoria Australia 🇦🇺
Lenny sure is a beautiful bus!
The GREATEST engine that man has ever put diesel in
Holy shirt. That sounds amazing!!!!
Beautiful sound! I would be proud to own a bus like that…
Lenny looks and sounds beautiful!
Surround sound engaged! Sounds great to me.
Always loved that throaty Detroit Diesel sound...
The bus is clearly in great shape. I will never understand the 20th century person's fascination with the noise of propulsion, however. The silence of the modern EV is bliss. The closer an ICE comes to that standard, the better, like the v8 boats of the 60's and 70's.
Nothing perrrr like the 71series😊
Lenny is a beast and sounds great.

love that sound Detroit sound
great job
What a sweet sounding rig!!
It is a sound of the past but like a 6 cylinder Jag when you hear it if you know you know.
What a great sounding engine!!
Those detroits sing a pretty tune
Sweet sweet music! Golden oldie!
This bus is 2 years older than me! 😎
God bless Lenny for making it up the grade
The sound of perfection!
How is Lennys interior fit out coming along.
He certainly is beautiful now that he's sporting a new paint job he's gotta be one of the best silversides around.
When I hear music like Lenny produces, I produces a big wide grin... (just can't help it!)
Yeah. Definitely a bad ass sounding 2 stroke!
Nothing else sounds better. So good to see Lenny stretching his legs.
Sounds Great ! Love It !
Lenny sounds great!
I love this bus!
Didn't even sound like it was working that hard, like it could outrun the newer stuff 👍
keep the clips coming
He makes it up!!
always love hearing the sound of a screamin jummy climbing a long hill
Brilliant sound ! 671 Helped win the war back in the day , very popular , such was demand you couldn't even buy one privately you had to be millarty or government office , really top design ahead of it's time , only immisions being multifuel killed the two strokes,
Thanks for the video.
Lenney sounds good. Looks like you got a new camera mount for very cool video angles. That’ll give you some good looking shots.
It does sound great. Would you consider recording every engine style 6V and 8V 71's and 92's and then make a montage of all-in-one video? Thanks.
Sounds sweet
Lots of power there
Awesome sound 😎
Beast mode 👍
Sure miss hearing those motors

How long since rebuild? Honestly, one of healthiest oldies I’ve heard!
It's amazing there's enough time for combustion and transfer of energy before the next revolution. I'm guessing there's quite a bit still happening in the exhaust based on the noise 😂
Love it!
Love it.
Nothin' like the sound of a "buzzin' haffa dozen"!
Love it
