12V92 in a truck is rare but it's not unique. Over the last few months helped a farmer here in South Australia get his '86 Peterbuilt long nose with 48" sleeper finished. The 12V92T is under the lenghtened hood with the cab pushed back on the chassis. The chassis has been lenghtened and built to Australian road train spec, doublers along full length of the rails with full air bag suspension. This has been a 6 year project that started out as an imported American left steer truck with a 6 cyl Cat engine. The farmer grows grain and there are a couple of hills between his farm and the silos, he likes to keep good time towing his fully loaded tandem tippers. The engines, he bought 2, came out of sugar cane trains in Queensland and were originally DDEC engines, he converted them back to mechanical governing for simplicity.
@@mikeaporter5231 The first blue truck is a 12V92, the gold one is a 12V71. 71's were the only series with a one piece cast V12 block, 53's 92's and 149's were two V6's bolted together.

12v92 crackerbox trucks were never even made it's a custom truck because 12v92 were not even around then they had the older model 12v71 was around but not the 12v92. They did not start making the 12v92 until 1974 and crackerboxes are older then 74
There was a jimmy like that in the Allentown Pa area back in the 80s. I heard that guy also passed away. Perhaps that is where this guy got the idea for his jimmy and putting a sleeper on stretch frame set up. I remember passing by the salvage yard where it was being built. I think they used a stake body frame under it. That truck sat for about 5-6 years before they converted and painted it. Then it disappeared. I don't know what engine was in that red truck because it sat behind a fence in a fenced in yard. The truck had belonged to a local electrical supply company it was a delivery truck for the business and I guess they sold it when it became outdated.
As an European. That thing look like it belong in the junk yard. No one would drive a truck made in the 70's here. but it looks to me that in murica stuff made in the 70's and in 2023 are just the same. While here in Europe stuff made in the 70's are mammoth bones compared to the high tech stuff we drive these days

The GMC Crackerbox might be the biggest nostalgia hit for fans of old-school heavy trucks. Everyone who grew up around big rigs seems to have some memory of their dad, grandpa, or uncle driving one, so it's a callback to America's childhood. In turn, clean examples are sought after in a big way, and they're relatively rare to spot in the wild. That's what makes this 1967 with a custom sleeper and twin-turbo Detroit Diesel 12V92 such a showstopper. It's a mighty project for sure, and it's sitting in a warehouse in Dade City, Florida, just waiting to be finished. Bruce Wilson featured the truck on his UA-cam channel, giving us a close-up look at the Crackerbox that boasts a 1,104-cubic-inch two-stroke diesel. It didn't come this way from the factory, and it's not currently running, but it's relatively close to completion. The current owners acquired this tractor from the original builder, who constructed the sleeper. GMCs like these are notoriously narrow; the cab measures just 48 inches from front to back. This reportedly allowed for wheelbase options as short as 108 inches, which was an advantage back in the day when truck and trailer combos were limited to 55 feet. The length wasn't a concern when building this truck as it touts tandem rear axles and a frame long enough to house the mighty power plant. Detroit Diesel's naming convention made it easy to know the specs of each engine. With this being a 12V92, we know it has 12 cylinders that measure 92 cubic inches apiece, all arranged in a "V" configuration. These famously made as much as 700 horsepower, and you'll spot a plaque underneath the passenger door with that number in plain writing. Historical records claim this engine alone measures 68 inches long, which isn't unbelievable considering it's effectively two huge V6s stacked together. The turbos are located behind the cab, where you'll also find a pair of tall twin stacks. Some of the piping runs into the sleeper, which doesn't have a floor yet. It'll certainly be more comfortable when it's finished than the factory option, which reportedly measured only 24 inches. There are odds and ends to tie up such as wiring, but even some of the smallest details like clamps and brackets have already been sorted. There's no sense in putting a timeline on the truck's completion, but just know it's in the caring hands of someone who wants to see it finished. Even the tiniest jobs feel big with a restoration like this, but I can't wait to see it on the road for the first time, whenever that is.
Thank you..... for regurgitating everything that Bruce already said and showed in this video. By the way, the 12-92T/TA/Ti's were capable of Much more, that 700hp. At that output of 700, it's barely above minimal rating for "industrial" ratings..... Marine versions were over 1,000hp. Even the 12-71T (with Twin turbo's & 7025 injectors), Mechanical, in some of the Terex haul/Mine trucks were rated at 925hp! The 12-71 that I worked on.. a Pro Semi sled puller, was "built" to 2,300+ hp.... and that was with No Modifications to the block or heads, internally. The reciprocating assembly was balanced, but that's all.... and it had 1.6M road miles on the engine before modifying it to 2,300+.
One of the first trucks I was assigned to after getting my “chauffeur’s” license in 1980 was a ‘67 GMC Crackerbox. It was a retired SRA tractor that the farm co-op I worked at decided to keep and use as a fertilizer truck. So they lengthened the frame and turned into a straight truck with a bulk fertilizer body. It had a small Detroit in it and a rare Spicer 5x2 transmission. It was the loudest, and roughest riding, rig I was ever around. But oddly, one of the best shifting for a cabover. With a steering wheel that made a man outta ya. Sadly, it only lasted about two seasons as the fertilizer dust took its toll on an already rusting cab. By the spring of ‘83 the body was repurposed and the cab & frame sold for scrap. I hated that thing at the time, but as the years have passed I’ve realized how lucky I was to operate a piece of history.
M dad was flown to Seattle to pick up a BRAND NEW crackerbox GMC in the early 60’s. It was a single screw, short 2 axle that he bobtailed back to southern ca to haul hay. He said his top teeth fell out. It rode really rough, but the 318 was kick ass pulling I-10 headed to Chino. On a different note, I used to meet drivers from “motor cargo” that had Cabover Petes with short cabs hauling tanks in Barstow, CA back in the mud 80’s. They hauled the space shuttle. Hell! They hauled everything. They had V-12’s with Allison automatics. Good times.
All two stroke Detroit's have superchargers they have to have them to run they don't have intake valves they intake ports in the sleeves air has to be forced into cylinders, very cool trucks
about 15 years ago i was working for a farming supply outfit delivering fertalizer. i was driving a '78 gmc general and i came to an intersection on a back road encoutering a cracker box similar to this one. they were hauling a loaded grain trailer with it. darn thing looked cherry.
Gotta love that 3406, had one in my 85 General. Put a big turbo and had her cranked up pretty good and put 515hp to the pavement. Pulled over 103k lbs every day. Did 2 weeks hauling concrete demo in a 45yd triple floor and wall dump trailer. Lightest load was 166k and one was at 183k made some real good money...... Best engine ever made..... IMHO
A friend of mine has a 1950 GMC cab over, unrestored, factory air ride, independent front suspension, 6-71 Detroit, 600000 original miles and it’s roadworthy. If you get around the twin cities area you may see it during the summer at different shows. It gets a lot of looks!
@@DDK1068.... Yes, there were. The GMC "Western" versions had Budd wheels as well as AIR Ride suspension on the tandems. There is one (1955), here in Montana... not too far from where I am, just sitting in a field with other's.... but the owner will Not sell it... I've tried several times, but "no dice". It also has Aluminum fuel tanks from the factory. It does Not have the IFS, as mentioned in "brianfrye's" comment above, but just the standard, front "beam axle".
Everyone I see these old rigs I think about how miserable it had to be to drive these things cross country back in the 50’s and 60’s. Those men were a different breed. Running coast to coast sitting on top of a screaming Detroit, no noise deadening
In the 80s Double Eagle made custom bunks for cabovers. The guy a whole in the back of the cab and had a zipper boot to access the sleeper. That way you can still raise the cab. Unfortunately they always leaked.
the 12v92 was predominantly a marine engine used in large ocean going vessels (tugs, supply vessels etc...) and yachts like Bertram, Hatteras, Viking, etc... They were used as generator units but used a lot more in a marine environment.
Steer axles with out brakes was quite common back then. Or there was an air toggle switch that could be flipped to shut off the air supply to the steer axles brakes. Labeled dry road/slippery road
Fantastic! Somebody needs to buy these gems and finish restoring them, especially the crackerbox. Such a shame that they're sitting in an old warehouse.
Great find. I’d love to have that. People want 10 times what they were worth new. Ran a V12 -71 in a Terex scraper, man could that thing go, foot to the floor. Oh the good old days
Shits heartbreaking to see all the guys who do stuff like this, dying off... God bless this family for protecting their patriarchs builds. That GMC is sick af and I pray it gets the love the resting original builder wanted for it
Werner Enterprises has a classic Freightliner that has a 16v 92 single block not 2 8Vs together. They had to stretch the hood 27in to get it to fit. This is their show truck that they use for recruiting
My dad had two of these when I was around 7 years old he was a tomato 🍅 framer in homestead FL .That was about 1974 . Him and my uncle would haul produce out of homestead every year . And back then he had a pice of plywood to sleep on when he did stop and rest .he also had a b model mack b61 with the Dana Plex transmission. And my grandfather had a Diamond Ro they were cool but in 75 my dad bought a cab over ford 9000 and I can tell you that ford rode like a bronco 500 miles you hurt from head to toe

Hi from France, i'm not a big Detriot Diesel two stroke fan,i drove a Cabover Kenworth with a 6V92TTA long haul for a while,so i kinda know 'em well.All that said how i'd love to drive that Kenworth,loaded of course,up and down a few steep hills,hope it's got a Jake (or more than one),just to see how they stand up.At 62 years of age now,i drive a modern European truck now,well i put it in drive (or reverse) not the same game. I miss those old bangers.
I drove a KW with a 92N 360hp in my first truck. We put 92t injectors in it and the transmission went out in the first 500 miles and they only had a 15 double overdrive so that went in. To pick up 15th gear you had to wind it up to 2600 rpm at 76 mph. On paper with the gearing it should've done 125+. The fastest I ever had it going was 95 and it started jumping from lane to lane.

My stepdad drove for GM for 32 years and the coolest truck he drove were two Astros with Turbines in them. I guess they didn’t have power they needed to haul 120k loads of steel they hauled here in Mi.
boilermaker1337.... Actually, it would have been a 6-53, not a 6-71. If you remember, when Bruce read the "Data Plate".... he said "250hp @ 2,800". I think it flew right over his mind as well.... because he never even "raised an eyebrow" when he read the "@ 2800". lol
The GMC COE is incredible! I'll bet you that truck would pull that building down. Older trucks like that had incredible engines and no pollution crap on it.
That truck will make someone a show stopper. Too bad the guy that started it, didn’t get a chance to finish and show it. That has to be pretty rare with the 12v-92. The other truck with the 12v-71 may have been originally specified, it was probably non turbo and someone added the chargers. Those trucks are something that needs to be finished and cared for.
My 77 Peterbilt 352 didn't have steer axle brakes, nor did my 77 White Western Star. Early tractors rarely had front brakes because the factory guys hadn't perfected them yet.
Or, the ones with brakes had a ''slippery road'' air switch that would disable the front brakes to avoid locking them up and losing control of your steer tires.
Technically, Brakes weren’t required on large trucks/tractors until the 1979 model year, mandatory 19790101, because until then the “pancakes”/diaphragms weren’t considered reliable enough for the steering axle, if and when they popped it could cause a jackknife.
I'm tired of hearing about that crack head(yes I've met him and know someone that use to work for him. I live in Sweetwater). Take that ole shit on to his channel.
Towards the end, when he said "WE" forgot to put this stuff away, last time.", was correct. If they were working TOGETHER, then their BOTH RESPONSIBLE. 😆
Well, when you're sitting right up over the front axle, you get quite the ride, and I ain't talking smooth. I drove one back in the 70's, 238 with a 10 spd (5spd and 2 speed axle), single axle. Screamer, slow as molasses except going downhill. Maybe that's why I'm deaf today?
My shop is the last detroit certified shop on the west coast 😌 we built the 24v71 in the thor truck a few years ago and are building parts for thor 2.0 as we speak. Gotta love some screamin jimmy
Front breaks weren’t on trucks till the early mid 70s , I always thought it was crazy no front breaks on big trucks, I suppose it just makes a fella pay attention more whilst driving
The reason we took the front brakes off those trucks was 2 fold. First benefit was to lighten up the front axle weight by around 400 lbs. The other benefit was the fact that locked up tires give you no directional control. If the tires are still rolling you still have steering control.
6V71s were called "screamers " , but I call them all screamers especially with that "V" those things were known for speed. 12V71s, 8V92s were in buses also.
Back in the day trucks that had sleepers on them where you had to get out of the cab to get into the sleeper , the drivers back then called them “ Suicide Sleepers”. I couldn’t tell if this was going to be that way once if it ever gets finished. Those Crackerboxes didn’t have hydraulic cab jacks on them, you just unlatched them & grabbed the handles under the windshield & put your foot on the bumper then heave-ho! Of course it helped if there was another hand around to help you, but with the aluminum cab a lot of drivers most certainly managed to go it alone. Imagine trying to take a nap in that bunk if for whatever reason you left the engine running, come on!
Funny you mention no front brakes. Lot of big trucks back in the daze had none. I remember driving part time in 1983, after loosing a good teamsters driving job when they put my Dads trucking company out of business with a crazy proposed contract, my Dad had had enough between the union, opec I II & III, then in 1981, de-regulation was the mail in the coffin. So I went on unemployment, from $13.18/hr pre-recession, taking home over $500/wk with plenty of OT, to collecting $136 a week! Then after my 36 weeks ran out, plus 4 weeks extended, I was forced to drive a truck for work a building supply company, the only job I could find at the time, that was bad. The owners weren’t too bad but very cheap paying. But had a nice fleet and equipment, but operated out of an old school building filled with asbestos, but that was back in 1984. The min. wage was $1.64 in Rhode Island at the time and they offered $2.00 to start, I was up to $2.25 in six months. So for straight 40 hrs with no overtime paid I too home about $64/week! So I needed something on the side. There was an owner operator who had a couple old bone shakers making a go if it hauling roof shingles and lumber, who didn’t need a full timer with him and his brother, but he has a side gig hauling clothing trailer for a clothing manufacturer in Secaucus, N. J. Up to a retail distributor in Foxboro, MA. that he paid me $100 cash to run, no handling only pin to pin, with an occasional Bob tail. That trip I could turn in 8-10 hours depending upon traffic, so a decent deal. But the truck was a first class piece of crap bone shaker 1966 GMC Crackerbox just like the one in the video, only a single axle, but a sweet running 6/71 Detroit with supercharger and the rack turned up. That with the 10 speed Road Ranger could top out at 76 mph!! Without front brakes! But the owner had added the best shocks he could get, with an air ride setup in the rear with good shocks, plus he always had NEW tires no retreads. I remember one Friday night like always, in a light rain with a buddy who rode with me, smokin and jokin all the way. But had to bobtail home! In that awful cabover Crackerbox! With no front brakes! Man was that ever scary! I had to drive like I had NO brakes! This was when there were toll booths half way through Connecticut! That trip took us till the sun came up I had to drive so slow! My buddy was terrified especially with no wiper on that side!!! Total pos, that ran and rode pretty well. The other truck he had was a beautiful of KW, twin screw, 190 NA Cummins with 6 speed stone crusher no Syncro trans. That rode like a brick shithouse. That old Crackerbox could walk away from that old beautiful Ty.
O-H-I-O Porter greetings.❄️ The Crackerboxes were quite unique trucks? I owned one for a few years…single axle,an ole 238 with oversized pistons. I gave it to my brother, who had planned on getting it running again. No front brakes… many of the old trucks didn’t have front brakes back in the day. And some of the tandem axles only had brakes on the drive axle…if you were parked on uneven ground, it would allow the truck to roll away. Yes, that’s true! That was one beautiful Crackerbox!🥰 I hope they do finish it…it deserves it. It sure would be an eye catcher!😎 Were you disappointed that you couldn’t fire either one of those trucks up? Good stuff! I’ve got to catch up on your videos since I’ve been away for a while. Blessings!🥰🇺🇸✌️

@@DDK1068
🤔
@@DDK1068.... Yes, there were. The GMC "Western" versions had Budd wheels as well as AIR Ride suspension on the tandems. There is one (1955), here in Montana... not too far from where I am, just sitting in a field with other's.... but the owner will Not sell it... I've tried several times, but "no dice". It also has Aluminum fuel tanks from the factory. It does Not have the IFS, as mentioned in "brianfrye's" comment above, but just the standard, front "beam axle".
Everyone I see these old rigs I think about how miserable it had to be to drive these things cross country back in the 50’s and 60’s. Those men were a different breed. Running coast to coast sitting on top of a screaming Detroit, no noise deadening
In the 80s Double Eagle made custom bunks for cabovers. The guy a whole in the back of the cab and had a zipper boot to access the sleeper. That way you can still raise the cab. Unfortunately they always leaked.
The one TS24 was naturally aspirated but the Loadrunner was a Tt 12V-71; twin turbo with 500 ponies. Ear muffs standard
the 12v92 was predominantly a marine engine used in large ocean going vessels (tugs, supply vessels etc...) and yachts like Bertram, Hatteras, Viking, etc... They were used as generator units but used a lot more in a marine environment.
I knew a driver that owned a Brockway with a v1271 Detroit
Yes, the racket engine, doesn't work well in the trucking application.

Hence, the barn.. 😢
Good stuffs and beat all European trucks.
@shemreed that's a lie 😅
It's amazing how smooth and quiet that 3406 is and can't wait to hear those V12 2 stroke Detroits 😁
Clatterpillar is good but just couldn't last as long.
Thanks for the video.
Safe Journey! CHOLULA!!!
Steer axles with out brakes was quite common back then. Or there was an air toggle switch that could be flipped to shut off the air supply to the steer axles brakes. Labeled dry road/slippery road
Wow!! Pieces of art and hot riddled... thank god there inside...
That Crackerjack is gunna be an absolute show stopper when completed. That KW is my dream truck tho. I had an L model with the same paint.
In terminator movie what truck they use?
Cracker box
@@dolguldur4706 tow truck or what truck?
@@Carla-tz7qw in terminator 2,the truck that jumped during chasing scene...whats the model name of that truck?
Freightliner. Badass jump. It was a tow truck.
Would love to hear the ole “buzzin dozens” live again in those 2 trucks. Nice find Bruce especially right down the road.
Fantastic! Somebody needs to buy these gems and finish restoring them, especially the crackerbox. Such a shame that they're sitting in an old warehouse.
Great find. I’d love to have that. People want 10 times what they were worth new. Ran a V12 -71 in a Terex scraper, man could that thing go, foot to the floor. Oh the good old days
Shits heartbreaking to see all the guys who do stuff like this, dying off...
God bless this family for protecting their patriarchs builds. That GMC is sick af and I pray it gets the love the resting original builder wanted for it
WOW! From the age when GMC and White were in bed together. I had a toy model of the White version. So cool! Thanks for inviting us along.
White was a tough fucking truck in the early 70's
Werner Enterprises has a classic Freightliner that has a 16v 92 single block not 2 8Vs together. They had to stretch the hood 27in to get it to fit. This is their show truck that they use for recruiting
My dad had two of these when I was around 7 years old he was a tomato 🍅 framer in homestead FL .That was about 1974 . Him and my uncle would haul produce out of homestead every year . And back then he had a pice of plywood to sleep on when he did stop and rest .he also had a b model mack b61 with the Dana Plex transmission. And my grandfather had a Diamond Ro they were cool but in 75 my dad bought a cab over ford 9000 and I can tell you that ford rode like a bronco 500 miles you hurt from head to toe
Like the old old iron and that cat motor sounds sweet
Love that old cab over, I agree semi casual should finish it and the ol KW needs to be fixed up so it can be shown!! Thanks Bruce!!
I drove one when I was 16 and it about beat my guts out. Cool old truck
Sorry to hear Roy passed I worked with him several years ago he was a very intelligent man and a great fabricator and mechanic...
One of the nicest things about those old Detroits is they are a very versatile powerhouse
Yep, they were extremely efficient at converting fuel into noise
@@moose.knuckle And motor oil into leaks
@@moose.knuckle...... actually, Mr."moose.knuckle"... they were and still are, Highly efficient at converting fuel into power, and do so with approximately 33% less displacement than a comparative 4 cycle at the same hp and torque outputs. That is also the reason why, in the world of Marine Diesels.... virtually ALL of the worlds Super Tankers, Container Ships, RoRo's, etc, etc.... with engine outputs greater than 55,000 to 60,000hp are 2 cycle.
Wow I ain’t never seen anything like that anywhere. A very rare treat indeed!
Hi from France, i'm not a big Detriot Diesel two stroke fan,i drove a Cabover Kenworth with a 6V92TTA long haul for a while,so i kinda know 'em well.All that said how i'd love to drive that Kenworth,loaded of course,up and down a few steep hills,hope it's got a Jake (or more than one),just to see how they stand up.At 62 years of age now,i drive a modern European truck now,well i put it in drive (or reverse) not the same game.
I miss those old bangers.
At first sight you said IHAVE TO GET THIS TRUCK
Really nice trucks Bruce thanks for bringing us along buddy appreciate it 👍
I drove a KW with a 92N 360hp in my first truck. We put 92t injectors in it and the transmission went out in the first 500 miles and they only had a 15 double overdrive so that went in. To pick up 15th gear you had to wind it up to 2600 rpm at 76 mph. On paper with the gearing it should've done 125+. The fastest I ever had it going was 95 and it started jumping from lane to lane.
That is an awesome find that cab over!!
That truck is absolutely incredible!
I agree!
You should keep that Cat 3406B and sell the rest of the truck. That Cat engine is gold.
Tim Gentry could probably use that motor.
thank you so much for making this video, i saw the short and couldn't wait.
😃😃😃😃😃😃😃
Very awesome find Bruce two of a kind and hard to find semi
When worked Peabody Coal in KY we had 12v71s in Haul trucks in 70s great engine.
Ur killing it Bruce! 👍👍
Crackerbox is almost a finished project. W900 is nice too. Don't let bruce get within 10 miles of either!
LoL.
That GMC is a beautiful truck. What a shame the man never got the chance to finish it.
They usually give thier life savings to the doctor to live 2 more years in pain rather than spend it on what they love.
@@chrishultgren777
For many ppl, it's one or the other; pain free, but no money for resto; other hand: have money for resto, but in too much pain to do it. Tough choices for some, right? 🤔
A gorgeous ride.😍🤩 That cracker box.
Somebody should sell this to Cody Detweiller he would give it the special treatment it deserves and really put it to the test.
thank god it's not for sale hate to see another truck ruined
My parents co-drove a '79 Jimmy cabover with a single sleeper with the 13-speed Spencer split for 15 years.
I've got one of those old GMC cab overs sitting in a local scrap yard close to my place... Unfortunately it had seen better better days... Sure it will be scrap soon... I think it's past it's restoration phase. I like the look of them as well. But this thing's amazing!
Such a beautiful truck. Would be one heck of a truck to purchase
This GMC is Insane! This work deserve to be finished.
Man that's a neat old Truck. Thanks for sharing this with us Bruce! 👍 Or should I say neat old trucks!
Beautiful crackerbox GMC. Love the color. The K whopper is kickass in that color and that engine. Damn sweet.
With no front breaks, road speed rpm and gear selection, and mad jakes outstanding
I have seen a Chevy cabover with a factory 12V71, impressive!
I don't want to hear this thing run. I NEED to hear it run! I REALLY hope someone finishes this beautiful thing, I've never heard a turbo 12V92.
My stepdad drove for GM for 32 years and the coolest truck he drove were two Astros with Turbines in them. I guess they didn’t have power they needed to haul 120k loads of steel they hauled here in Mi.
Originally 250 HP sounds like it probably only had a 6-71 in it when it was new.
boilermaker1337.... Actually, it would have been a 6-53, not a 6-71. If you remember, when Bruce read the "Data Plate".... he said "250hp @ 2,800". I think it flew right over his mind as well.... because he never even "raised an eyebrow" when he read the "@ 2800". lol
King Jimmy this one is . Best crackerbox Ever. Who was hiding this . Wow
The v12 kW you could get the V12 from the factory I have friends that have those
My need is *greater* than yours! What a great truck; like a time capsule. Thank you for sharing!
Absolutely a Screaming Jimmy!😎😎
Love the old Jimmy ❤️👍
The exhaust mainfolds on the KW 12v71 are custom made. The original would have been cast iron.But bruce does not know KW did build w900s with 12v71s..
I'm wondering if he knows half of what he thinks he knows. Obviously daddy pays his way
What manifolds are customer made ???
Gr8 CLASSIC TRKS with BIGG V12 HP!!!!!! 😎💎🔊
Mr Wilson the thinking back in those days for no front brakes is that they thought that the front brakes caused jackknifeing is what my Dad told me🤔
The GMC COE is incredible! I'll bet you that truck would pull that building down. Older trucks like that had incredible engines and no pollution crap on it.
That was a beautiful Cabover too bad he never got to finish it sad but still it is a beautiful cabover👍🏼
I'll love to see that truck finished
To the contrary, Bruce - anytime I see an old half collapsed barn, I *always* think, "Hmm, wonder if there's a '43 GPW Jeep, etc in there!"
Use to run OTR, and often saw old trucks in clumps of trees, out in fields and often wondered when I’d see a big enough barn: what’s parked in there?!
That truck will make someone a show stopper. Too bad the guy that started it, didn’t get a chance to finish and show it. That has to be pretty rare with the 12v-92. The other truck with the 12v-71 may have been originally specified, it was probably non turbo and someone added the chargers.
Those trucks are something that needs to be finished and cared for.
My 77 Peterbilt 352 didn't have steer axle brakes, nor did my 77 White Western Star. Early tractors rarely had front brakes because the factory guys hadn't perfected them yet.
Or, the ones with brakes had a ''slippery road'' air switch that would disable the front brakes to avoid locking them up and losing control of your steer tires.
Technically, Brakes weren’t required on large trucks/tractors until the 1979 model year, mandatory 19790101, because until then the “pancakes”/diaphragms weren’t considered reliable enough for the steering axle, if and when they popped it could cause a jackknife.
My father ran a 3406 cat.. great motor, pulls hill like a rockstar
Cool old GMC, the KW isn't bad, either.
The first truck I ever drove was one of these cracker boxes Awesome 👌
Bruce do a joint build with Tim gentry that would be amazing to see both teams build something sick
I'm tired of hearing about that crack head(yes I've met him and know someone that use to work for him. I live in Sweetwater). Take that ole shit on to his channel.
Towards the end, when he said "WE" forgot to put this stuff away, last time.", was correct. If they were working TOGETHER, then their BOTH RESPONSIBLE. 😆
No one wanted to drive one of them back in the day 😂 now everybody wants one!
Well, when you're sitting right up over the front axle, you get quite the ride, and I ain't talking smooth. I drove one back in the 70's, 238 with a 10 spd (5spd and 2 speed axle), single axle. Screamer, slow as molasses except going downhill. Maybe that's why I'm deaf today?
My shop is the last detroit certified shop on the west coast 😌 we built the 24v71 in the thor truck a few years ago and are building parts for thor 2.0 as we speak. Gotta love some screamin jimmy
Front breaks weren’t on trucks till the early mid 70s , I always thought it was crazy no front breaks on big trucks, I suppose it just makes a fella pay attention more whilst driving
The reason we took the front brakes off those trucks was 2 fold. First benefit was to lighten up the front axle weight by around 400 lbs. The other benefit was the fact that locked up tires give you no directional control. If the tires are still rolling you still have steering control.
Sweet find 👌😉👍
The 6V92 was popular in rear engine coaches, but mostly marine applications.
I drove a truck with an 8V92T. She screamed down the road like a scalded ape!
We had them in the rear on our terex scrapers. Very good.
You should see if Tim wants that motor for one of his trucks if you still have it.
6V71s were called "screamers " , but I call them all screamers especially with that "V" those things were known for speed. 12V71s, 8V92s were in buses also.
I bet Tim gentry would do a badass job finishing it
@George Tim is the Jesus of semi trucks, show some respect
You mean stripped apart
Got to love the kitty. Cumapart do have a chance.
Give Peterbilt Mike a shout.
He needs motor and transmission for one of his trucks.
Back in the day trucks that had sleepers on them where you had to get out of the cab to get into the sleeper , the drivers back then called them “ Suicide Sleepers”. I couldn’t tell if this was going to be that way once if it ever gets finished. Those Crackerboxes didn’t have hydraulic cab jacks on them, you just unlatched them & grabbed the handles under the windshield & put your foot on the bumper then heave-ho! Of course it helped if there was another hand around to help you, but with the aluminum cab a lot of drivers most certainly managed to go it alone. Imagine trying to take a nap in that bunk if for whatever reason you left the engine running, come on!

Funny you mention no front brakes. Lot of big trucks back in the daze had none. I remember driving part time in 1983, after loosing a good teamsters driving job when they put my Dads trucking company out of business with a crazy proposed contract, my Dad had had enough between the union, opec I II & III, then in 1981, de-regulation was the mail in the coffin. So I went on unemployment, from $13.18/hr pre-recession, taking home over $500/wk with plenty of OT, to collecting $136 a week! Then after my 36 weeks ran out, plus 4 weeks extended, I was forced to drive a truck for work a building supply company, the only job I could find at the time, that was bad. The owners weren’t too bad but very cheap paying. But had a nice fleet and equipment, but operated out of an old school building filled with asbestos, but that was back in 1984. The min. wage was $1.64 in Rhode Island at the time and they offered $2.00 to start, I was up to $2.25 in six months. So for straight 40 hrs with no overtime paid I too home about $64/week! So I needed something on the side. There was an owner operator who had a couple old bone shakers making a go if it hauling roof shingles and lumber, who didn’t need a full timer with him and his brother, but he has a side gig hauling clothing trailer for a clothing manufacturer in Secaucus, N. J. Up to a retail distributor in Foxboro, MA. that he paid me $100 cash to run, no handling only pin to pin, with an occasional Bob tail. That trip I could turn in 8-10 hours depending upon traffic, so a decent deal. But the truck was a first class piece of crap bone shaker 1966 GMC Crackerbox just like the one in the video, only a single axle, but a sweet running 6/71 Detroit with supercharger and the rack turned up. That with the 10 speed Road Ranger could top out at 76 mph!! Without front brakes! But the owner had added the best shocks he could get, with an air ride setup in the rear with good shocks, plus he always had NEW tires no retreads. I remember one Friday night like always, in a light rain with a buddy who rode with me, smokin and jokin all the way. But had to bobtail home! In that awful cabover Crackerbox! With no front brakes! Man was that ever scary! I had to drive like I had NO brakes! This was when there were toll booths half way through Connecticut! That trip took us till the sun came up I had to drive so slow! My buddy was terrified especially with no wiper on that side!!! Total pos, that ran and rode pretty well. The other truck he had was a beautiful of KW, twin screw, 190 NA Cummins with 6 speed stone crusher no Syncro trans. That rode like a brick shithouse. That old Crackerbox could walk away from that old beautiful Ty.
O-H-I-O Porter greetings.❄️ The Crackerboxes were quite unique trucks? I owned one for a few years…single axle,an ole 238 with oversized pistons. I gave it to my brother, who had planned on getting it running again. No front brakes… many of the old trucks didn’t have front brakes back in the day. And some of the tandem axles only had brakes on the drive axle…if you were parked on uneven ground, it would allow the truck to roll away. Yes, that’s true! That was one beautiful Crackerbox!🥰 I hope they do finish it…it deserves it. It sure would be an eye catcher!😎 Were you disappointed that you couldn’t fire either one of those trucks up? Good stuff! I’ve got to catch up on your videos since I’ve been away for a while. Blessings!🥰🇺🇸✌️
gotta love a old cracker box!!! I think thats the same guy that but the W925 that runs around town pulling reefer!
That kenworth engine suprised me! 😍
Yep , a great restoration unmolested that needs a little finishing.
You know I got to be honest I’m not really a KW person, but could you imagine the stories that truck could tell
