Steve worked hard on THIS,throw him a thumb.

No, Katie is wagging her tail saying, "No, Mr. Magnante, that's not correct." It's easy to determine a GMC and a Chevrolet in these years by the VIN. GMC trucks use a letter for the model year, while Chevrolet trucks use a number. Some characters were also in different spots as noted below. Correct, this is a 1970 Chevrolet C30 cab and chassis with a hood from a GMC truck. Correct, engine suffix code "TAR" is a truck engine, a 307 V8 for 1970 with a two barrel and approximately 200 gross horsepower, manual transmission used on the 3/4- and 1-ton vehicles. Yes, with the VIN, you win: C for 2WD conventional chassis, E for V8 gasoline engine equipped, 3 for 1 ton rated, 3 for cab and chassis, 0 for 1970 model year, T for Tarrytown, NY assembly and the rest is the production sequence. The Tarrytown (North) or "Sleepy Hollow" Assembly plant operated from 1896 (as the Stanley Steam Car Company) until 1996 when it last assembled the "Dustbuster" minivans through June of 1996. It was purchased by GM in 1918 after Chevrolet was integrated into GM by that time. No SPID, wish you did, but this is possibly code 505 Dark Green exterior paint. The plant was a known gross polluter of the Hudson River and it was said that you could tell what color vehicles that they were painting on a given day by the color of the water. A 1970 GMC equivalent VIN would be something like: C for conventional cab 2WD, E for V8 gas equipped, 3 for 1 ton rated, 03 for cab and chassis, T for Tarrytown, NY assembly, Z for 1970 model year and the rest would be the production sequence. Correct, you can order a cab and chassis from Chevrolet and GM today, but anything bigger than a 1 ton is only available as a Chevrolet in their "HD" line. GMC does not have a equivalent as of this writing. This line has been a poor showing for GM versus Ford and even Stellantis, as not many dealers have signed up for taking on the line. Several dealers I know won't even touch it, even with prodding from GM executives. Many of those executives recently took the GM buyout package and are now gone. The HD line is produced alongside of the Navistar equals in their Springfield, OH plant and Fontaine's Springfield, OH facility is the main modification location for those trucks. I've been to that location and it's a big warehouse of vehicles in various stages of modification. It's about an hour away from Columbus, OH on Eagle Road in Springfield off I-70. Yes, many times there were homemade bodies made by industrious folks, especially in places like New England.

Reason why kadie is so well trained around Steve Mags is cuz he brings a little snack of roast beef. Lol.

Cool old truck, look at the old wrecker in the background, would love to see/ hear more about it.

I worked in a cemetery during college. We had a few vehicles modified like this one. Some were rebuilt and repurposed, some were modified brand new. I can still hear the dump bed extending in my head. Thanks as always for the education and hard work ~ Chuck

My mom had a 69 Chevelle Malibu 307, with a powerglide 2 speed, it ran OK, 200 hp. It was a bit of an odd bird, red, white vinyl top, black interior. In 1974 she traded it for a Camaro, 350 2 bbl with a whopping 145 hp. What a gutless slug, no more burn outs, for this teenager at the time! Lol

Good morning Gents 🇺🇸

These videos are addicting, Bernardston Museum of Automotive Antiquities.

Thanks Steve! I'm willing to bet that El Camino is your next installment, good stuff!

Surprised that dump bed setup is still there. I’d use it in a heartbeat.

Steve... you deserve the Congressional Medal of Honor.... or maybe an Oscar. I don't know, but I love watching your videos. PLEASE DO A VIDEO ON THE 1965 Chrysler 300, NewPort, NewYorker~!!

I have to say, Did everyone pay attention to how nice that cab is in, Good cab corners, looks like strong floor. Hard to find cab, anymore.

Nice. Please do the tow truck in the background. 👍🏻

Those were very good trucks, and very popular with farmers, a flat bed with removable side racks or just a dedicated livestock box were very common. I drove several of these trucks and the only thing that might have made them better, would have been a 2 speed rear axle

Believe it or not some people actually wanted wood dump bed trucks depending on what they might be hauling. Certain farm chemicals are corrosive to steel and also if your hauling salt you don't want a steel bed unless it's made from stainless but those cost quite a bit more than wood.

You dont find this type of content often - chock full of interesting history. Hoping to see Steve's numbers up there with Demuro and Hoovie someday. Keep up the great work. Videos make me want to go visit junkyards.

30 years ago i talked to gentleman that had 20 of these 67-72 truck stashed in barns from panels wagons to custom trim sports, i asked why, he told me i will be a classic truck one day, local chevy dealer has a 71 gmc half ton orange/white 350 engine/air/pwstr. In the showroom 71,000 dollars, but those square bodys are starting to creep up in price to along with those ford dent sides!

Once again, not split rims. Lock ring wheels. Perfectly legal. It's also worth mentioning, cab and chassis rear rails are different then pickups. Cab/chassis have flat rails, 34" on center, industry standard to make fitting custom beds easier.

I have 2 of these. Both straight 6, with “4” speed transmissions. One has that roof the other no. One is same color as interior but with small back window. No arm rests. I like the window rain guards on it. I would have taken them. Good stuff as always!

Katy rules, Steve drools!!!!!!!!!

Always a joy, always informative, the vast knowledge shared is a wealth by Steve mags....only missing the fun gouge at motor trend...is that a subtle whining like a bad power steering pump I hear...lol

One of my fondness memories was my 70 Chevy C10 pickup. I was 1979 and it was one of my first Vehicles in life. I put an aluminum cap with Curtains, all the way around 😂.. Enjoy your episodes.

Uh, Steve... the Monitor and the Merrimac were both IRON-HULLED ships!

Forgot the exact requirements but clearance lights are mandatory for certain width vehicles

great video once again. queen katie was doing her best to steal the scene, Saturday morning, cup of coffee and the crawl. Great way to start the weekend!

I saw one of these yesterday ( New Zealand) but it was a '69 C20 , and it had signwriting on it " LA county lifeguards" or something like that , might have had " Baywatch " on it , probably a tribute ? Whatever , it took me by surprise.

About 30 years ago i picked up a running 1971 Chevy 2WD with a 307, 3 spd on column. 3/4 ton. Cost? $100.00. And it ran. Had an 8 foot factory wooden bed which was rare since most of the beds made were metal. And if i remember right, if someone here can correct me. I think the 307 was rated for 215 horsepower since it was in a 3/4 ton. Great video Steve and always on these videos a thumbs up from me!!!

Steve I put a 307 in a 87 3/4 ton Truck, My 350 had a rod knock, I modified the bolt holes on the throttle body manifold, I have to be honest, That motor Ran Great with injection, Purred , Strong, on hills 4 speed truck. No smoke passed emissions every year.

Great video! Such ashame to see that rig, rotting away in the boneyard. 😢 Looks like a very solid truck. Hate seeing these oldies go to die

I had one with the 305 ci v 6 what a beast at least between gas stations.

In the late 90’s when I worked at a Chevy stealership I had to move a few of these bedless heavy duty trucks. They did great burnouts!

We had a '73 C60 on the farm. 350 cube 2bbl. 2 speed rear. It did everything we asked it too. It had an overspeed light that came on if you started pushing the motor too hard. Had an earlier model with a 292 six banger in it too. Great hard workers. Liked gas aloy though

Good morning from Vero Beach

GMH in Australia offered the woeful 307 as an option for a few years before the vastly better local 308 came out. Amazing how people got sucked in back then thinking they were getting some sort of road burner because it was a chev V8... even worse was the 305 they optioned though.

Just out of high school I bought a Chevy Cab Chassis thinking I could make a dually pickup. That is when I learned the Cab Chassis frame was 4” longer from the back of the cab, and the axle was much too narrow. The drums were right against the springs. A dually pickup would have been the correct length for a 8’ bed, and had the Dana 80 that was much wider. Live and learn!

Mr. B. Here ! ☕️☕️🍩🍩 Morning to all ! Steve when the Mrs. & I lived in Mass I drove many of vehicles that ! The feeling was mine blowing it felt like you lost part of the truck ! Have a good day ! 👍👍👍👍

My Brother Bud had one of these . The Granny Gear was so Powerful that you could dump the clutch and it would not stall . Even sitting still with the brake on and clutch engaged !

Knobs on the aftermarket radio appear to be off a ‘61 or ‘62 full-size Chevy…….🤔 My dad had a ‘72 C20 and when he would go down to our local Skelly station for his Saturday morning fill-up, I remember sticking my head out the driver side window and smelling the sweet emanating fumes of that leaded gasoline as the tank was being filled via the cab-mounted filler! That right there likely explains a lot of things in my life………😂 Growing up, one of our “country neighbors” who had a good job at the cardboard box factory bought a new Ford half ton every two years. Always dark blue, always with a white aluminum topper (very similar in styling to the truck bed camper shown in Steve’s brochure) installed on Day 2, and always with a set of (I’m assuming aftermarket?) marker lights mounted on the cab roof! One of the more vivid visual memories I have from my childhood is his truck driving slowly by our house just as the sun was going down with his marker lights glowing bright orange in the Minnesota twilight……..👍

I love you katie , don't look sad hunny . Just walk back home to your loving parents.

Good morning from Canada. 👍👍🇨🇦

I don't think I ever watch one of these without learning something. I had a '71 F350 so a lot of this is familiar. BIL got A '70 C10/20/30? from my dad that had been part of a fleet build for a utility company. His best bud was a tool set up man at ball bearing company that had a contract with GM. also a VERY! competitive G stock drag racer with mostly Pontiacs (So he knew his stuff!!!) That truck A short bed stepside , had a commercial step van front end and a 2 speed Dump truck rear end. and a center carrier bearing for the 2 piece driveshaft (This was a Short wheelbase truck , remember) That was completely of unknown origin. BFF had access to the complete GM Data base of blueprints. for such parts. BIL did get a ticket for driving out of class once when carrying a load of 1's & 2"s after he had built the bed up with plywood Long Ways! (8 foot high!) cop said he only stopped him because he saw gravel falling of the top of his load! Having worked in high end manufacturing for many years I know what it takes to get something built in production. I would wonder how those Chevy COPO Cars could be factory built and then I thought about this truck!

Steve, you win the trophy for the Most Natural 2 Tone Jersey ! Your a Cool Dude but not during this video shoot ! Again ! Good Presentation !

I have a 1999 C3500 1 ton dually; With a Heil dump bed. In 99 they weren't known as a cab,& chassis; They were sold as incomplete from factory to the dealer who would out source the body you would want put on; Such as Box, stake body, Or a dump bed. My truck is quite loaded with options, snow plow equipped; plow blade was removed when I bought it used; Tinted windshield, power steering, A/C , & a am/fm radio. The engine is a 5.7 with a automatic trans. With disc brakes up front, & drums on the rear. The best thing about the truck it only has 53,000 on the clock.

The 307 I built for my 69 chevelle was a tire smoking machine. Had a 465/488 282/292 adv duration cam and an edelbrock performer and a 600 double pumper, and headers. The rest of it was stock internals. Ran 15.80 in the 1/4 spinning tires to 60’.. I’d have a 307 any day over a 305

I believe that the only determining factor regarding the addition of clearance lights is the vehicle width

I enjoy every video. Thanks Steve. Please stay hydrated.

Small businesses and farmers built those dump boxes. I am always amused by the concern for gas tanks inside the cab. Only real bother was the smell after filling or if there was a small leak. Much like the gas tank under the driver's seat on a Jeep. Not ever really considered a fire hazard and I don't no how many died because the tank was there. Seems like there were more complaints from rear and side mounted tanks. It might be more of a perceived problem much like COE vehicles.

Cool old truck.

My second car when I was 16 was a 1970 Nova with a 307. (First car was a 1963 corvair Monza coupe). I worked at a speed shop called Hi-Rev after school and weekends, and I tried everything to wake up that 307....headers and twice pipes, Edelbrock intake with a quadrajet, even a crane cam. It was still a pooch. Being a dumb kid at the time, I never addressed the fact that it most likely had a 2.73 rear axle and the powerslide trans didn't do it any favors either. So honestly, a can't say if it was the 307 or the drivetrain that made it gutless with any certainty...but I'm thinking a combination of all the above. My third car...1965 nova/ 327/ 4-speed was a VAST improvement!

Steve great information on the truck. The cab lights were optional on C10, C20, K10 and K20 trucks. I have a few of these trucks that have them from the factory as an option. The RPO code for the option was "(U01)". As far as GMC or Chevy easy to tell from the front headlights. GMC has four lights and Chevy has two. GMC usually had the gauge bezel painted to match interior color also, whereas Chevy would be Black or woodgrain covered if Cheyenne or CST truck. Once again great information on the truck.

Nice truck. Back in 97 I had a neighbor who was a Brick layer. He had one that was a flat bed.

Had alot of these trucks when I was younger at that time you could get them pretty cheap 50 to a 100 bucks third hand and very well broke in

dont be so hard on that 307 they had a 327 stroke and 283 bore the first 3 years 307 production they were in 327 blocks we built a number of them bored to 4inchs with good results, the later light weight casting blocks were no good however.

My dad had a 1967 C10 Chevy p/u. dark.grn. small r/window, straight 6,3 on the tree....he bought it brand new... I learned how to drive on that thing when I was 12 years old! Great memories!

307 were known for eating the cam lob on #8 cylinder I had one in a 68 impala

He man I’m not 🦀 crab lol another good show Steve keepem comein

Oldie but a goodie

I started calling cab and chassis trucks “Kenny chesneys” a few years ago. Makes my wife laugh every time.

Great (informative) video. Don’t mind those MT guys! Keep the Crawl videos coming! Gearheads unite!

I like that el Camino or sprint in the background!

Way to go.. Mr Steve

In cab gas tank! Nice!

I had a 1970 C/10 Suburban with the 307...i promptly pulled it out and put in a 66 283. It ran so well after that... combined with a sunroof, stereo and Cadillac power front seat...

The later sidesaddle gas tanks werent all that great either.

Still looks pretty solid.

Doesn't cost you anything to subscribe. I can't imagine watching these videos and not giving Steve a like and subscribing.

Excellent video Steve! 👍👍💯🇺🇸

Thank you Steve

@3:33 is a big red Dodge truck, which uses the late '50s pickup cab! Dodge used that cab as late as 1975, I believe, on their Big Horn conventional road tractors.

Morning Steve....that cab and chassis look to be in descent restorable condition. Throw in an ls,chrome buds,wood stake bed,and you've got a descent oldie. It would be a labor of love .

The Ford store I worked at in the late 80's sold a pretty good number of cab and chassis, mostly 3/4 and 1 tons. One morning, I can in and someone had stolen the outside duals off of one and the exhaust system off another. Believe me, a dually with no duals looks goofy as hell, and a 460 with no exhaust sounds awesome.

My friend had a C20 with dual wheels and a dump body. At least I believe it was a C 20.

I remember when the 1988 Chevy and GMC trucks came out while working at a Chevrolet dealer. The corporate Chevy rep told us the demand for the Chevy Cab & Chassis, and Suburban trucks was so huge, GM could not afford to stop the assembly line to retool their Cab & Chassis & Suburban plants to retool for the new body style for a couple more years.

One question that came to mind on these old one-tons - did the manufactures beef up or use different frames for the heavier load-rated trucks? Obviously springs, suspension components, axles, and housings were stronger. Over the years I’ve seen a few old pickups, usually half ton long beds that looked like the frame was bent around the juncture of the cab and bed. And when I did see them, they were on the road loaded to the gills.

My brother had one of those in the early 70s, he’s was a stake bed truck. He used for his iron works. Boy I remember it so well. 3 speed manual on the column. What a great truck it was! Great video Steve.

Yeah, the 307 was the 283 bore and the 327 stroke. Still fit Chev power pack heads.

1985 I bought a 1968 C-10 from the estate of the original owner for 500 still have it to this day.

Cab ID lights are not required on trucks over 10000 lbs GVW. They are required on trucks over 80 inches wide, so other vehicles can see that a wider than normal vehicle is approaching.

The 307 is a 327 crank in a 283 block . That engine can easily be made to make 300hp , Easily with someone who actually knows what they are doing !

Do the el Camino next

@ Steve......Sadly most people DO NOT realize or understand that a small block Chevy 307 is basically a large journal 327 block!! The only difference is the size of the piston bore, and if you ram the thing out to a 4 inch bore, it becomes a 327 cubic inch!! Another thing that is often over looked in the stroke in the 283 small block, 327 small block and the early 307 CHEVY small blocks are all exactly the same!! BUT in the late 1970s the 307 cubic inch engine used in the 1978 to 1984 Malibu, Cutlass, El Camino, Phoenix, Skylark/ Apollo/ Regal, were actually built by Oldsmobile and based off the 350 Rocket engine!!! And the late 1960s and early 1970s, 307 engines all had a bore of 3.875", just 0.125" short of becoming a 327!! So the point to that last sentence IS, there is plenty of "wall thickness" to punch a 307 out to a true 327 cubic inch engine and then swap the pistons from a 4 inch bore (327) engine into it which fits directly to the connecting rods you already have in the 307!!

The cab roof lights, wasn’t required per GVW, but was required on all cab/chassis trucks, and anything sold with a wide bed on it, stale bed, box truck, chassis mounted camper…. If it was wider than the cab, it got the lights. However, if it was a one ton with the 9 foot stepside bed, or the 8 1/2 foot longhorn fleetside bed… lights weren’t required. As for the C-10 and 20 trucks you could get the cab marker light optional, with the raised stamped mounting pad. K series 10 and 20 series had the option also. Some of the GMC trucks of the era had some weird VINs.

Thanks Steve and thank you Shane. Katy too.

Great video Steve! We had a tow truck with a Holmes 440 tow body. it was a really nice package you could get int spots that a 5 ton couldnt. We had a friend that had a C 30 ramp truck. It had a 396 with an Eaton 6 speed(n0t original!) #.5 rear axle it would cruise at 75mph. We built a sleeper onto the front of the ramp body with a pass through to the cab He had a nice 67 Camaro A M/P

Put that engine and trans and cab on a 1/2 ton probably get 20 mpg. Trucks had the short water pump, rams horn exh. etc. nice motor. Bet it runs, its a chevy....

Nothing wrong with an inline six. Seven main bearings vs. Five in a V8. JUST SAYING.

If that truck was restored it would make a great tow vehicle for some of the bigger toys.

I had a G-30 passenger van(1983) back in the late 80’s and early 90’s. 350 four barrel, 16.5 inch wheels,etc. Great reliable truck. Gas milage on the other hand…

Doctor Wrecking with his trusty four legged assistant nurse Ms. Sniffy.

Nice 1 ton. ❤

Classic Rag gas cap haha We used to do the slam on the brakes and listen for the splash in my friends 67 Chevy when gauge failed,one positive about behind the seat tanks.

67-72 Chevy trucks had a single headlight vs GMCs Quad headlights. Thats usually how I see first glance. Didn't know 69 had the grill trim blacked out only for that year. I know my old 69 Custom Camper/20 saddle brown, white top, black underline. It had the black out shades on the grill. But what confused me is when I see both 69 & 70, (which has that style grille) seeing both truck years at a car show with blacked out trim.

The GMC trucks of that vintage had 4 headlights where the chevys only had two.

I never knew that about the lights pads. There's a 73-77 ElCamino or Sprint photo bombing there.

You’re leaking coolant I see! Doing your weedwackercise again? Great Video, Steve, I look forward to them every day! I guess we can call off Investigator McGruff, on the Katie Botulism case, she looks fine! But, we’ll be watching you mister! LOL!😂

Good job on the cab roof catch. My dad was a Chevrolet zone rep during this time period and had to actually scrap a brand new Chevy truck that showed up at the Chevy dealer in GMC trim. Obviously built on the same assembly line. I thought the first digit of the VIN’s were different for each of the GM line before everything went to country of origin for the first digit. No clue

I worked at a GMC dealer. We would get trucks in with Chevy horn buttons. Tail gates and the fenders with Scottsdale on them

Hi Steve, good video! The lights on top of the cab, are mandated to identify the truck, bus, trailer or any vehicle that is OVER 80 inches wide. The fact the the truck that you profiled is equipped with double rear wheels falls into that mandate. The three center lights identify the vehicle as over 80" wide, and the the far outside lights are clearance lights. Please reply. Dave...

IN THE EARLY 90'S I BOUGHT A 72 CHEYENNE I BELIEVE WITH NO BED/WOODEN BED! PAINTED BLACK WHITE AIR CONDITIONER WOULD WORK PISSED ME OFF SO I TRADED FOR BUICK LANDAU 6 Six which blew up on me! Kicking self in ass!

Interesting bit about split rim's being outlawed around 74, as export models had split rims for decade or so later
