That’s the single most bad ass 4x4 diesel I’ve ever seen.

Wow, a Toroflow!? The Anti-Detroit-Diesel from when GM could afford to compete against itself. So few of those exist. That's a rare bird. It sounds absolutely great.

I cut my teeth on that truck! It was brand new when I got hired at Aptos Fire Department. Later I when became the Chief Mechanic for the dept. I worked on that truck for years. There were 2 of them built same time by Howe Fire Apparatus in Martinez. I ran into one of them about 20 years ago on Santa Cruz Island. Yep, Napco front axel.

To you young men out there… General Motors actually knew how to build trucks at one time

I live in monterey ca. I have seen this truck in the early 1980 s in Aptos ( Aptos is 10 miles from Santa Cruz Ca) will never forget it, all the kids loved this truck!!!!

Awesome choice on the wheels and tires. I think it looks even better than before.

That's a badass truck like no other....I can hear the f550's quivering in fear of the monster brute!

What an awesome piece of old iron. When I was just a small kid, my Dad looked at buying a Toro-Flow diesel GMC flatbed truck for his contracting business. A neighbor owned a GMC dealership at the time, and wanted to make a good deal for Dad to buy the truck. My Dad finally decided that the truck was just a bit too big for what he needed and bought a 1-ton gas GMC flatbed instead. The Toro-Flows received some modifications in 1969, renamed the Toro-Flow II. The engine was renamed the "Turbium" for the 1972 model year, but few referred to the engine under the new name. The Toro-Flows main problems were head gasket leaks and fuel injection issues. I suspect that the fire department specified the Toro-Flow diesel because of the ability of the diesel to withstand very long idle times when in use--an ability which post-2007 diesels no longer have without causing emission system problems and repair expenses. The Toro-Flows were never big sellers during their era, in part due to the fact that gasoline was cheap and readily available. Up until the late 1970's, diesel fuel was largely only available at truck stops and bulk oil jobbers. As you noted, the Toro-Flow is pretty fuel efficient. The comparable GMC gas V6s of that era wouldn't get half of that fuel economy. My Dad's 1-ton GMC with the 305 V6 gas would only get around 9 mpg, at best--but that engine was a "puller." As you likely know, those gas GMC V6s had a sound all of their own. Decades after my Dad sold that old GMC, I can instantly recognize one of those GMC V6s just from the sound. The gas engines would run forever, too. The NAPCO 4WD conversions were bulletproof units that saw extensive use. That is a great truck--I would have likely gone back to standard wheels and dual wheels in the rear, though. If the Toro-Flow ever completely conks out, I suspect that a Detroit 6-71 or 6V-71 would be a bolt-in replacement--both bulletproof engines.

That truck is badass. By 1975 GM was building their own 4wd medium duties right on their own assembly line. I worked at the plant that built them.

This is definitely one of the best gmc truck ever built. Know I'm on the hunt for something like this. BowTie till I Die guy.

For a grocery getter that’s gonna be one big grocery bill! Man I’m dreaming of the amount of tasty things I could buy from Costco and haul home in that truck! Thanks for sharing and for sparking some day dreamin.

You made an old guys day! Granddad had a 72 C10 loaded to the gills, 350, auto, power windows, ac you name it. I thought that was the prettiest truck I ever saw, I loved it as a young boy. I just think you are a super young man for what you do with these old trucks. I bout had a conniption when I saw what you were pulling the big truck out with. Then the 71-72 era truck you hauled the big girls tires in. You are a special guy and I want to follow you because at 72 years old my love for these trucks, some of the best and best looking ever built is strong as ever! Thanks for putting a BIG OLD SMILE on my face and reminding me of my Granddad and the beautiful truck he had (Green top, white between the chrome lines and green bottom, a nice sea foam green) way back in the day. The old big GMC, she is a charmer for sure! Thank you, and God bless you for pulling these old trucks out of barns and fields and bringing them back to life and usefulness! It is very heartwarming for sure! Subscribed this video, first of yours I ever watched but certainly not the last. Thanks again, be safe and keep hunting until all those old Chevy's and GMC trucks get restored and on the road!

I bought a 72 Ford C900 Fabco 4x4 boom truck. This is bringing back memories of 1992 when I flew to San Diego and drove it back to the Bay Area. I still have it, and it has done a ton of jobs for me.

'67-72 Chevy & GMC were the best trucks ever built and this one pushes that envelope!

That truck is bad ass what a sweet find you killed it with those new wheels and tires I'd drive it with a smile if I had it

Man, so many memories of the GMC v6's, both the gas and ToroFlow. Remember the sounds well, as a car / truck crazy kid in the 1970's!! Thanks for sharing this gem, and not butchering it. All these new bloated, overpowered but poorly built modern pickups have mostly replaced real medium duty trucks due to cost in many applications, but some of us remember what real trucks are. All these "Hot Shot" wannabe truckers with over rated / over loaded 3/4-1 tons really need to step up to a real medium duty truck, lots safer and cheaper in the long run.

I absolutely love it. My Dad had his own construction business and had mostly 67-72 work trucks. Even a 72 1 ton dump. I learned to drive a 72 3 on the tree. I had my own business and had an 84 International DT466 dump truck so this to me is the perfect truck. Wow, I truly would love to have one such as this. Great video, thank you for sharing.

67-72's have always been my favorite trucks. The Napco and little rear window are super cool. Looks like a little piece of heaven at your shop!

THIS!!! Wow. So rare and cool. Keep us updated as to if you find 22.

I LOVE anything old GM diesel. Anything 6.5 and older. This has got to be the sickest video I’ve seen in a very long time. This truck is literally priceless as there is nothing to compare it to. The sound of an N/A v6/v8 diesel cannot be beat. Time to find another 6.2 😊

Great job on finding this , great story with it ! I'm glad you got it and didn't destroy it! Keeping old gems original as possible is the best part of finding one. That's a one of a kind beauty! Keep her up ! If you ever paint it to protect it, you got so many options ! If you do paint it, do it right you got this far , she's badass! Nice job saving a rare & beautiful truck !!

My favorite part is that besides the big front end and the huge bed and running boards, it's just a 72 cab . Awesome truck

Thank you for sharing your truck with us. There was a red cabover grain truck for sale here in Nebraska 10 years ago at a farm auction with a Toro Flow. I've read some posts online over the years, some guys who had Toro Flow diesels back in the day were running a blend of used motor oil with their diesel and said they had no problems, I don't recall the percentage of the blend.😂 Ahh, the good ol' days

In 1970 I had a 56 Chev 1- 1/2 ton...261 cubic inch in-line 6. It had the NAPCO kit so it was a 6x6 with 22.5 wheels. I hauled a lot of Cedar bolts and firewood with that beauty. It was originally a pole-line truck for PGE. When I bought it, it was minus the big box and boom and winch. I put on a flatbed and racks and a 10 ton winch. I had salvage contracts in the Siuslaw National Forest from Mt. Hebo to Florence. Ran that baby for years and sold it to a friend when I was getting old and tired...

As a teen in the early 2000s who helped restore several 67-72 c10, c20 and k20 trucks in the rust belt, I can appreciate this truck

It's been a long time since an old truck made my blood pressure rise, even longer since I even took a second look at a new truck, but that thing is f###ing awesome.

That is a awesome truck!! I found a firetruck similar, mines is a international 1970 4x4, i changed the pump house, and put a chev bed on it

Cool truck. I'm glad to see someone drive it instead of letting it waste a way.

My Grandad Had 1970 Pea Green C20 Custom Deluxe Factory AC Rear Leaf Springs He Carried His 10’ Alaskan Camper With It Many Fond Memories As A Kid.

Clark she’s a beaut! Love the late 60’s early 70’s GM Trucks. Thanks for sharing!

Wow, that truck is somethin else! Everything about it is just so unique and youre one lucky man to own that!

What can anyone say,,,,, this rig is the best thing since sliced bread. I never heard of that truck before. What a machine. Wow. It knocks me over my friend. Love to have one like it. I think I put it in my living room & just play in it. ( Wife will just have to big D. Me.).

That's a beast! Everything about it screams 'MERICA. Guaranteed to be well maintained during it's life before private service

9:27 😊 what a great sound ! I hope the Toro Flow lasts a long time and you can leave it in there. These are getting rare indeed. I'm so jealous when I hear that sound on that drive you took.

That would make an awesome tow truck. It doesn't matter where you are stuck that thing can come and get you. I'd even go to some insane place to get stuck and would grin from ear to ear seeing that thing coming to the rescue.

Nice truck. I think it's cool that your perserverance finally paid off and you ended up with something really special.

I just saw a video about the Toro-Flow, it's super rare. Great find!

Yet another GMC I wish I had in my garage.. Good job on saving it!!

This video is awesome, from the truck, down to the WA state pride and the Vitamin R. Glad to say I cracked one open while watching this video

Congratulations on having the coolest, most bad-ass 4x4 on the internet !

that has literally got to be the perfect truck!

Napco put together some really good stuff.

Nice Washington plates, and the little state sticker on the back. I love it, hopefully Ill see it in person one day, coming from Vancouver!

Those wheels & tires are the icing on the cake

Really kool truck man. Slotted wheels are insane. I grew up in my grandpas junkyard in south bend, kelm’s auto wrecking, not to far from you. He had a half track he used to pull cars around. I really dig those early 70’s late 60’s 2door trucks ya have as well. I will b back to check out more episodes. Thanks.

Badass Beast with a unique sound. I always know when that one is coming down the road.

Dude, what a badass truck, it's so crazy to hear about rare, almost one off GM products. Watching that part where you and your buddy designed and built replacement wheels blew my mind. I've never seen something like that. Cool truck!

Years ago there was a guy in our area who put a Toro-Flow in a F250 crew cab 4 wheel drive, Called it Diesel Dorf. I believe he got his Toro-Flow out of an old milk truck. Nice find on the 550 and I appreciate you keeping it in original condition. The only thing I would do to it is try to find or remake the battery box cover. you'll have to try to match the diamond plate. New subscriber.

Cool ole truck with great utility

I had a 1965 GMC dump all wheel drive of about the same weight as yours - it had the gas V6 - which I rebuilt - loved that truck

I've heard and read about the Toroflows but have never seen one in the wild. Warms my heart to see what you've done to resurrect and preserve the old girl and 14 MPG is amazing. My 72 Sierra Grande 402 BB that I've owned for 50 years can only do 10-11 MPG if I drive nice ;-)

What a machine! Congrats on picking it up and bringing it back to life. It's beautiful!

That's so cool,and those wheels are perfect for it!! I've heard of that engine several decades ago but have never seen one in person,only in a drawing in a very old magazine way back in the day.. Apparently, it's got plenty of get up and go even for a na diesel,and the gearing seems pretty good on it from this video... Thanks for making this video and sharing with us ..

Once in a lifetime find , sounded like 2stroke Detroit at first

Those cab lights are awesome.

Very cool truck, nice to see the old girl on the road again.

Man I haven't seen or heard one of those old toroflows in years. There were a few around in my area but they never really caught on. They just didn't have the guts for anything over 30 - 40,000 gvw. When I was in the Army and stationed at West Point I was in the motor pool while waiting to go on my years vaca in S. E. Asia. I was a bus driver while there. We had those old toroflow diesels with Allison transmissions in our post buses. So if you need parts for it you might possibly find some old military surplus bus parts. I'm giving my age away. Good luck on your truck! Nice ride.

Great video. Never heard of a Toro-Flow engine. Truck looks great!

Is it just me, or does it sound like a duramax? This truck is so cool, I would say it would be fun to have one, but the story you told about its history is even cooler. Only two are way better than saying 200 or more

The enginesound when you came up the hill in the end, awesome! 👍

what a toy its magnificent on its own

That is one Kool Truck!! Ir's hard to believe that it runs so good!! That will be one great shop truck!!

Very sweet GMC service truck 👍

Looking at this truck, it just screams badass.

As a fellow lover of the '67-'72 models, mine is also diesel powered with 4-53T DD ,plus 5 and 3 transmissions . Your Toro Flow makes it super rare, not a cookie cutter assembled with aftermarket parts from Summit Racing . I assume the Allison is MT 41 with lockup converter . I have almost 40 years/ 300K miles on my diesel conversion in a 1 ton stepside .

As soon as I saw it, I immediately thought "Westport Fire". I saw it many years ago for sale down there. I could even have some pictures I took at the time. I was thrown for a while when seeing your reference to its being in eastern WA. I tried to interest a King County area fire entity to purchase it for wildland fire use, but it would have been too much of a "project" for them. I'm really glad to see it with a continued life. **Yup, I have about a dozen photos when it was for sale in Westport, in the Fire Dept lot. Not sure how to connect if you are interested.

That truck is cool ! I've always loved that era of GM trucks. I have a 1994 International 4x4 Ex-Fire Truck that I made into a dump truck. It has super singles front and rear like this one, just a little newer is all.

I absolutely love this rare beast. Great score.

Thats one of the coolest trucks I've seen!! What a find,definitely a one of a kind! I'd definitely would be interested in seeing a follow up video if ya update it! Great job on it so far! A battery box cover would be nice!

Wonder if I can talk the wife into a detour to Oroville next time we head from Tacoma to CDA to visit her folks... seeing this truck in person would be worth the drive!

Absolutely love it from the Pilbara Western Australia . A factory custom beast. Needle in a haystack.

It wasnt that long ago (4 decades!) i had a Napco converted 58 GMC 2 door "suburban" truck. The stock 6 cylinder was gone, but still had the Trans, Spicer transfer case, and Axles. Someone had converted it to a 350 previously and i bought the truck with a rod knock in that engine, putting in a 307 marine takeout engine. I had to re do all the steering knuckles, had to come up with new tie rods & pitman arm, even scored a decent steering box. Installed a 50-gallon fuel tank for off road security. Did most all back roads, byways, and highways in northern AZ and Southern UT with it, drove it to Texas on a road trip, no working odometer or speedometer, but i figure i put near 100,000 miles and got away with only 1 speeding ticket while i had it. it was a great truck, a real ratter but with class, y know? I had it long enough to take my 2nd wife on our honeymoon with it. That was 32 years ago.

That’s one cool truck buddy

Crazy-cool old truck! It apparently went to the right guy who was willing to drop some cash on it.

Really bringing out the kid in all of us

Nice job getting the truck back operational again… 👍🏾

Very cool truck!!, Thanks for keeping it on the road

I love outside the norm stuff like this. It sounds just like a Detroit and I was thinking that's probably what it had in it at first glance. Surprised it had 5 lug hubs and glad you changed it over. Also really surprised it ran and all the guages still work. Very cool.

so funny Steve M from Barrett Jackson did a backyard junkyard crawl today on these trucks and motor! That’s awesome! Still got my wife’s grandfathers 1987 Topkick 7000 10 wheeler dump I restored. kudos to you loving these old trucks me to ! gained a Sub!

That’s just a cool truck, nice job keeping it on the road

Awesome. I’m jealous as an avid old truck guy and a firefighter and antique fire apparatus enthusiast. I know all about those rare hard to find things… I had a 38 ford 1.5ton pickup that I was gonna build but a move forced my hand to sell… now I have acquired a 1946 Chevy DS 1 ton pickup. The thing has one off parts that I can’t find well but when you do they are big $$$ like running boards. I will probably have to build my own when that time comes.

I HAD A TORO-FLOW IN AN INTERNATIONAL TRAVELALL, MINE WAS THE "D", BUT IT HAD THE "DH" PUMP ON IT 18 MPG ALWAYS/ANY CONDITION, AT 70 MPH ON ICE IN OVERDRIVE I COULD LIGHT UP 4 12.00-16.5'S... LOVED THAT TRUCK, IT ATE U-JOINTS LIKE POP-CORN...

I had a 68 ?brush truck with the big gas V6 for speed 4x4, split hood, it was awesome it was given to my son if he could get it started he brought the damn thing home we loved it until the city made us get rid of it but we did get to give all the kids in the neighborhood rides in the big red fire truck.. truck

super badass, loved the floats but it is fresh now

LOVE THIS THING!!! AND I'D NEVER GET RID OF A TOOL BOX!!!

Hey thanks for the shoutout on the pinstriping, by the way I love that truck and can say im a little jealous. 😊

AWESOME truck!! Would LOVE something like that and my dad would've too. Look forward to more content. Especially with that truck.

GR8 FIND, GR8 WHEEL/TIRE JOB!!!

That has to be one of the coolest vintage trucks I have seen in a while. Great find and great job!

That is an awesome truck! Well done, keep it drivin!

I could only imagine driving this thing on a backwoods pig trail. 2-way traffic is reduced to 1-way.

That is one badass truck! Love it, it's just a beastly thing that makes the kid in me smile! And it was rotting in a field, one of 2, glad you got it up and on the road, and not only on the road, you put it back to work which is awesome. I'm gonna keep my eyes on this one.

The Starter for that old chevy diesel is compatible with all of the 6V50 series Detroit Diesel!! I bumpt into a few of them in ARMY war stock my maintenance team and I had the same problem the starter was bad so crossed reference the starter in the US ARMY supply system and the Detroit Diesel one fit!!!

I would not have thought about the tire \ wheel issues involved. Truck has found an awesome home and use.

That’s the COOLEST of trucks!

Awesome! I drove a 'haywagon' version, when I was barely a Teen; I popped the Clutch (hell, barely Reached That Pedal, even, Yet, then!), and toppled 3 tiers of Hay-Bales, that afternoon, and had to 'flop' them back up onto the bed, by myself. Some Farmers expected better from us kids than was the Reality, but, I Did Learn how to double-clutch and NOT over-Rev in Low Gear, so...

What a beautiful monster!

Fantastic truck great looking wheels you got yourself a winner there

Definitely a sweet ride, truly is one of a kind. There’s no doubt about that and I like the way you did the wheels. Hope that truck lasts you a lifetime.

Great find, cool rig. Hell I tought it had 18/22.5s on it from the start then you said 19.5s then I remembered a Fire Dept. I worked for had a 1970 Ford F350 4x4 that had 19.5 floats on it. Firestone used to make the 18/22.5 super all tractions the looked like a big ground hawg tire, Bigfoot had them when Bob first built it.
