1973 GMC Sitting For 13 Years - Will It Start? 

I don’t know why, but i love this video. :-). Keep old things alive!

This is how you had to equip and modify a truck of this era to tow heavy loads reliably before the advent of $50,000, 490hp 3/4-ton trucks you can buy off the showroom floor. The trans is a TH400 with a huge cooler and that air-cooled trans pan. It's probably been rebuilt once or twice already. The overdrive unit is there because back in those days even the 454 was only about 210hp, so in order to get a heavy trailer moving they put 4:10 gears in the rear. That made highway driving miserable because the engine was spinning about 3,000 rpm at 60 mph. It wouldn't HURT it but it was loud and probably got about 8 mpg. That's why the auxiliary tank and that hugely complicated switching system are there, so they didn't have to stop every 100 miles and fill the tank. I noticed there's a belt guard above the AC compressor. The cruise control is aftermarket. The engine has newer valve covers and isn't orange so I figure it's been rebuilt at least once as well. That's a super nice truck, but modern girly-men would last about 2 days driving that rig around as stiff as those ride before they would run screaming back to their comfy luxo-trucks.

I love those older, non-computerized trucks. They're easier to work on, and parts are still available for them.

Oh dear...the mice! You’re a sweet soul. Great video.....thanks for sharing these wonderful days

What a nice, well preserved truck. This one strikes a chord with me. My dad bought a 1973 GMC 3/4 ton pickup that was the exact same color, except it had a vinyl seat. It had a 454. I think he bought it in late 1979 or so. I was really young. I remember he didn't have it for very long. He put it on a dyno at the dealer and they said it was losing 50 horsepower somewhere. Dad did some work on the valves with no improvement. He traded it in. I do have fond memories of that truck. So nice to see one in such great shape! BTW that's the first time I've seen the spare mounted on the rear bumper. I'm sure most of us over 40 recall all the pickup trucks that used to have the spare hanging off the front grille - a serious wind drag!

That thing is a BEAST!!! I had a 1982 Custom deluxe C20 like this, although 6.2L Diesel/TH400, CB and all that jazz. Was a nice truck. used it for parts on my 1982 also K10 diesel. Anyway. Not every day do you see those Overdrive units. Easily $500 right here.

And you rescued another 454 big block. Love it. Can't wait to see more videos of Jimmy

I had a 1976 Chevy 4 door Silverado pickup with a 454 about 30. Years ago I had the truck from 1990 till 2006. It rusted out. That 454 was a runner in its day. I could work on this truck myself .It was the same color and same seat colors as the 1973 Chevy 4 door pickup that youre going through good luck sir. I hope it starts. Sincerely Richard Dodds. So Sioux city Nebraska.

That truck is super clean. And looks so cool, there’s a special place in my heart for them old Chevys

Guy that had this rig before knew what he was doing. Reminds me of my grandfathers truck.

OMG my dad had a 1974 Chevy pickup and he had his hide a key box in the same location in the front passenger side hood.. Brings back many memories..

Geez, the finest example of a barn find. What a beaut!

That's a REAL truck right there. I would take this truck over rusty any day,just because the no computer bs ,plus these were just great solid trucks. And nothing against rusty, i am regarding to if this was also a vehicle that if you fixed and got off the property you could keep. Great vid as always Nathan.

Dad had a '74 GMC 3+3 454 Camper Special too pull our 5th wheel camper growing up. Gold with wood grain in the middle, that thing was a beast!! Wish I had it now!! Great memories seeing this one! Great work getting her running!👍

that is crazy about the mouse food storage in the air filter , ive seen mice in old cars before but wow!

That truck is absolutely gorgeous. Great find, kudos to saving it!

I love older Chevy truck i have a 1995c1500 200.000mais running great i love it ❤️

Nice job on the carb! It looks like it was pretty well taken care of. I'd liked to see it buffed out and cleaned up! Nice video! 👍

Loving this long video. Thanks for allowing me to unwind after a long day with you just calmly and methodically bringing that sweat machine back to life.

Watch out Rusty, Jimmy's back...Jimmy's gonna give you a run for your money...Jimmy's back...Keep up the great work! Awesome, and I learned something too.

Wow!! That's a true barn find there!! And it's in pristine condition by the looks of it. If it was to ever go up for sale,it would most definitely bring a very good price.. I'd LOVE to have it myself. But I'm all the way on the other coast (Ga).. And it purrs like a kitten too!!!

This is one of those once in a lifetime barn finds. Finding one in that condition with a 454, nice interior and what appears to be minimal rust. It also should be exempt from emissions. I'm not a Chevy fan, but if you decide to sell it, do it on your channel page. I'd take it in a heart beat. New subscriber by the way.

Dang that truck,is clean for 13 years lol mine would have all sorts of life growing in it and rust holes every where

Great work Nate! Very impressed with your work ethic and positive attitude, truly inspiring. Keep up the good work. Rod Boyle The Wirral UK

that's a nice truck worth some money by the looks of the shape its in

Good looking GM Squarebody

I just watched a guy clean up Mouse Droppings and clean out two gas tank's hunt for keys and rebuild a Carb. for over a 1.5 hours. Loved it and I want to see part 2 ! Mr Class A Living, I have a place for you to park and a bunch of projects to work on, if you want to come up a bit North of Spokane. You are a good Hand! Best to you. Keep the Videos going.

Excellent job. It may not be in perfect shape but damn those old GMs were built to last!

Awesome stuff. Maybe my favorite video of yours so far. Super satisfying revival of a sweet truck.

You guys out there on the west coast are lucky to have such a good climate that a truck that old can survive in that shape. In NJ where I'm from, even sitting in that building that old truck would have a bunch of rust on it. And if it had been driven regularly, it wouldn't have survived the elements here. It probably would've gone to the scrapyard 30 years ago completely rusted out.

Good deed goes out finish you found they keys brother 😊

I'd love an old truck like that. All set up for heavy duty towing and haulling. Extra coolers and even one of the air flow trans pans they used to sell. Always Smart to keep an air filter on the car/ truck it keeps mice from getting into your engine and destroying it with pee. That stuff eats metal. Fixing an old Q-jet you best replace that crappy Phenolic float. It sat for years and soaked up the gas. It will keep flooding soon. A brass float is so much better.

Nothing like the solid trucks! Good job

Saved those mice and in return you got the key lol good job man

Thanks a lot great movie. All the best you are a special person.. 😎👍

Really enjoyed watching this video! Please do more of this kind if you can.

beautiful and original GMC truck

Awesome job Nathan love the long video the suspense was a cliff hanger lol

Accelerator pump... overcomes the inertial lag of the normally aspirated gas engine... FI engines have an extra volume "squirt" programmed into them.. just to mimic this old technology mechanical accelerator pump. Great barn find.. especially if it's from a member of your family... I'm a Porsche / Mercedes guy, but the 454 was areliable beast in my old Winnebago .

Great job, now you have two great trucks!

Boss: Why are you late... Me: I was watching a guy vacuum mice out of a truck....

AWESOME!!! and in great condition!! i have a 74k5 blazer i am working on. good job brother!!! keep it up!!!

been watching your channel for so many years. i really enjoy these start em up videos. maybe you should do a start em up section on your channel just travel around neighborhoods look for old cars and ask the owners.

Thank you so much for taking your time to post it’s a real help ! Feeling that one love

In Russia, pickups are not popular, but I would buy such a handsome man. Watched the video first and to the end!!! Like=) "With love from Russia!=)"

Man you have a gold mine that is one nice truck It's like a time capsule I remember riding in a bunch of those but that one is nicer I think than the one's I remember. You just don't find them in that condition anymore. congrats

I love both trucks, very good job. Check the horn, must be a mouse there

What's up man you got skill working on cars man Love You episode man can't wait to see the next one lots of love from Pocatello Idaho

Nice-looking truck hope you keep this one

i love that truck!goood work on getting her back up and goin

That's a DAMN good looking truck u got there!!!

Super Cool Truck 👍 I have a 1985 Chevy Allergo RV and she runs Great 😁♥️

Nate, you're a wizard!!!

Funny how you saved the baby's and they led you to the hida keys. Karma's real people

To unlock the door fast, Get the loop around the lock and twist the sting. It will close the loop and you can pull up.

Nice 1974 GMC 3/4 Ton rig man,Keep up the good work man.

Yeah nice truck and the good Karma with those mice handed you the keys.

Dang nice find!! That's a pretty clean old truck!

Flip the air cleaner lid upside down just the lid... It sounds awesome 👍

Thank you for the great video. Love the old square bodys . That truck is amazing . I subscribed cant wait for more great videos.

old 3/4 ton chevys with 454 was my go to towing trucks untill i bought my first 7.3 ford

Wish i had the money for that truck, it would certainly be worth the trip to come down just to see it, and maybe drive it back home, or just trailer it, and haul it back to Oklahoma.

Cool video Nathan there is no end to your skills & talent and i can see why they want you hanging around the ranch 🔧🔩⚙🔨to fix things up ..those baby mice were cute nice of you to give them a chance ...keep the great vids coming mate 👍

you never said where you found this gem.

Thats a 90's 454. Pretty cool with the aftermarket equipment , and overdrive too! The tilt wheel handle was probably right where the tach is.

Man I’m in love with this truck!!!!

Awesome. Loved this extra more. Beautiful truck

Dryer sheets keep mice out of vehicles put under seats up in dash and under the hood in trouble spots really works.

I like your fortitude. You will try anything.

we still have my Dad's 78 1500 Sierra Classic he bought new. 350 with 4 bolt main

I had that exact truck when I was in high school... Except it was only 5 years old then.

That truck is in 👌 mint condition

excellent video, thank you.

You have to keep this Gem!!!

Used to use two allen keys and vice grips to open the quarter-light, one to pull the button in and the other to flip the lever, and while working on it open quarter-light so you don't accidentally lock the door with the keys inside.

Great video! Thank you

Belo acervo de pick-ups!!! Parabéns pelo vídeos!!! Abraços.

That tank in the corner of the bed and electric pump is an old "Vapor Kool" system that spray a mist of water on the top of the radiator to cool the truck under extreme conditions, they work fantastic! the company was in Highland ca, Jerry Duns was the inventor

great job kid

48:40 in my days wrenching on a chevy 350 motor, the fuel filter was in front of the carburetor. The filter was above the mechanical pump between the pump and carb. This all looks custom. 😮

Good looking truck there!

Man what a beauty, love the videos

Great achievement I love this job

God bless your soul for entertainment.

Lmao you keep referring to everything as "rusty" come to Ohio, ill show you what rust is. You guys are so blessed with beautiful rust free trucks its insane. I can only wish to find something that clean around here

That's my dream truck . 2nd vid ya should show that overdrive trans got a little glimps of it like a transfer case. Cool vids

Man I love your videos been watching forever now keep them coming! Is this truck yours now?

Good job!!! I'd love to see a video of this truck being detailed... :-)

Love that old truck would love to own one again

Great job!

That truck is so mint.

You are a genius!

Ive watched every video of yours and this is the best one! Bravo to you bud!

cool video and amazing truck liked and subbed

Good job, nice truck!

What a beautiful truck man I'd ask the home owner if you can keep both of the ones you got running

That's a really nice truck

Slipknot oh my God that reminds me of my 1980 Bonanza I'll tell you probably any old Chevy key will work those ignitions were pretty worn out easily in those days

the engine looks newer poss 1990s also if you want to keep it running a minute longer you can put gas in the stand pipe at the carb right by where you were squirting gas into the carb , just a thought.

You can take a fixed blade knife and slide it into the wing window and pop up the lock and slide your arm in to unlock.
