beautiful truck

I love all the engines GMC experimented with mid century.

Beautiful truck, sounds like a big heavy V-8! My dad had a 1966 GMC with a 351 V-6 and 4 speed. Pulled like a train!!!

My goodness what a gorgeous truck! And that big V6 is one of the coolest engines they ever made.

I didn't know about this v6! Good job. Nice vid!

This man is just living the dream. Incredible vehicles there!

Nice looking truck, my hands hurt just thinking about another restoration. But u did her good, kept her looking sharpe without cutting or modifying her. I think 67-72 were absolutely the best years for these trucks.

Thanks for sharing.i never knew a V6 engine existed like that.the exhaust is incredible. Enjoy the fruits of your labor

all gearheads born after 1950 are smiling while watching this video.what an awesome truck.

First 'auto' engine I saw torn down for rebuild. I still remember my grandpa using the burnt piston as a giant ashtray....

W.T. ……………..sounds like every parts store I went in had a piston on the counter with cigarettes burning in it , brings back good memories !!!! wait maybe they were bad would not have been there if I had not broke something ?????

That is one beautiful beast of a truck, too bad it took 7 years for KZread to let me see it. Good job on the truck!

I love to see when someone does such a clean beautiful classy job at building a vehicle. This is a such a nice truck, very clean & classy.

Great truck and great V-6 engine. I heard a lot of good things about these engines back in the 60's. It's a beautiful truck.

Wow what an absolutely beautiful simple machine. Just great! The work done and the result is perfection.

..exactly!...the only things I would change if it were mine, is I'd go back to the grill being polished aluminum, not black...paint the "GMC" letters on the tailgate, probably white, and switch the black wheels to some 10" wide stock-style steelies painted either white or body color with stock chrome dog dish hubcaps..that's just me...:)

That is a beautiful truck for you to be very proud of. You've done a meticulous job of making it nice & clean. Congrats. I'm currently pumping up the power level on my 250 I6, a 74 engine in my 81 4wheel drive. Love the old stuff.

Thanks for sharing! There was a time when I considered a swap in of that motor but I waited too long and lost my chance. Great to see this one!

Update, now that I have a gear vendor overdrive unit installed, the best fuel mileage I have attained is 15.5 mpg and I average 14-15mpg. I could still use a little more gearing so I'll probably switch to a set of 3.55 gears I have at some point.

+noshsreqd that gear vendors overdrive is an awesome investment I drive a 1984 F350 as my daily driver right now and i tow a very large travel trailer with it as well ,,factory gearing was .410 final drive I added a gear vendors ovrdrive to it and added 4MPG right off ,, it so impressed me that i changed the rear axle gears to .355 further increasing my highway fuel mileage ,,I am running a 6 speed manual which is adapted from a 99 F350 diesel truck,,, my engine is a mildly built turbocharged 478 big block ,510HP at 2800 rpm 710 #/FT at 2400 ,,cruising at 70mph on the highway engine RPM is just over 1200,when in double OD , barely enough RPM to keep the turbo producing boost ,, with the addition of the 355 gears and the gear vendors overdrive I am getting an amazing 21mpg highway with no load ,, and still manage a healthy 11 highway and 9 in the mountains towing my camper which weighs a very healthy 16,000 pounds ,,,, my mother laughs at me when we go places as a family cause I'd rather drive my 22ft long battleship than cram into her 2008 jeep liberty with the rest of the family ,, and it gets the same mileage as my truck

dang it I love this truck! Good work bud you have done an awesome job with this beauty. Absolutely love those big block V6's! great upload

I never was around the gassers but remember the 478 Toro-flo diesels in the tandems well. Good old engines. Had a G-model Prentice knuckle boom loader with a 5x3 in it.

Nice work on the engine. Looks new.

Nice! Glad to see it's got power steering with that beast over the front end!

great looking truck, and thanks for saving the V-6, I too love the old v-6's

Nice truck,love that you kept in GMC powered, don't know about the 92,and newer Ford mirrors,but that 68 is nice.Sharp 63 LCF.

This thing was built so well. Ford made good strong trucks back in the day too. But these trucks were very well made. I'll bet if someone brought one of these trucks to my shop, I could still align it. I used to own a GMC V6 with a granny gearbox. You could walk with it as it drove. About a mile per hour.

Glad that the 478s have found really nice homes ,love the 63 , never was a big fan of 67 to 72,to much 64 to 67 gm midsize styling ques for my taste. I love the v 6s ,to many Chevy engines in bays that should have v 6s . Thank you for keeping these great engines alive .

This video should break the interwebs very soon. People are going nuts about vintage 6 cylinders right now. And you sir have one of the biggest v6 gassers ever made. Thanks.

That is a beautiful engine, and beautiful truck!

Love how you went with something totally different, killer exhaust tone too. Great truck too! Hahah.

Boy o boy, that is so beautiful. What a great engine...

Perfect build man! Love those old GMC V6's!

Beautiful truck! I love the attention to the small details and that engine looks like it came from GM in that truck

That's awesome man , very clean very unique . Very impressed

sweet .. just bought a 1964 GMC 1000 FIRST TIME EVER SEEN THIS V6. MINE IS A 305E V6

Man that is slick looking. what a great restoration.

I have a Toyota FJ40 with a 351 V6 that I installed about 20 years ago. It stalls at 250 RPM and breaks axles at 350 RPM! With a 500 RPM idle. I have dreamed of having the 478 but this is the first one that I have seen. I pulled the exhaust manifolds off of a 402 with a rod out the side (the largest I have personally found).

That works out to about 80 cubic inches per cylinder...wow. Very nice truck btw.

I had a 478 toroflow gmc Deisel in my shrimp boat for 20 years , great engines

That motor must pull great in that pick em up truck. I drove a 1971 gmc single axle semi tractor with that exact same motor... 5spd with a 2spd axle. Fun to drive if pulling an empty trailer... put a lil weight on her and you needed all 10 speeds. Would run 55mph and think it was turning upwards of 4000rpm if I remember correctly. Beautiful job on her.

I just bought a naked 454 block to build up and put into my stepside, now I want one of these monsters. Can't have it all I guess

So clean! Nice attention to detail

That's what torque sounds like

Great sounding truck! I once put a 330 oldsmobile and automatic transmission in a similar truck (68) and tossed the 307 "cam eater special" . It was way easy and also good great fuel economy! Great video!

A beast! Nice work!

Awsome job on this truck i also like how you did some thing different from the norm the 6 was a nice touch

Very clean Installation!

Love unique combos, very nice truck.

I rebuilt a 478 years ago for a customer , only one I ever saw . Seen several 305s and 351s and a couple of the 702 V12s . I have always wanted to find one and do a project around it .

There are still some kicking around out there, usually see them on craigslist, quite often still running in a truck. I've put 50,000 miles on mine now and still love it, I always think GM missed the boat not utilizing the 401 and 478's in pickups, they would have ruled the road back in the day.

One of my dream vehicles is to own a GM truck with one of these big block V6 engines. Very neat.

Beautiful restoration.

This damn thing sounds like a v8 on the idle! Never knew there was big blocks v6’s gm thats pretty awesome! Especially a 478 v6 is bigger than the 454 v8 its pretty impressive!

Always loved the big block v6s. Used to have a old as dirt GMC dump truck with a 305 or 351 V6 cant exactly remember. It eventually got so worn out it got scrapped.

Great looking truck and amazing work

These big block v6 engines are cool sounds good

it's a beautiful job. really nice work.

Beautiful job all the way around. I just got a 68 C1500 with its original 351E V6 and 4 speed manual trans. MYine has dual exhaust added also but not as nice as your setup lol. Great job!

Wow what a cool engine. I'm sure it was hard getting parts

Wow, that is a rare bird for sure. Nicely done.

Whatta awesome truck. Great job, man.

Sweet looking & sounding GMC V6 😁👍

That nice truck sounds like a V8 at idle. Very nice truck and an amazing engine.

BEAUTIFUL, BEAUTIFUL, BEAUTIFUL is all I can say. Love your truck, great job.

Sounds sweet, looks clean. Well done!👍

WOW this is awesome!! I've been way into these GMC engines ever since I first learned about them and if I had one, I'd do it almost exactly like this. Well done, sir... this is beautiful.

Absolutely gorgeous. Sounding great too.

Late 60s I chased parts for a GMC dealer/garage. Saw lots of the V6s including a few in single axle semi tractors.

That would sound soooooo much better with a balance pipe in the exhaust between banks.

kennethrobinson11231-you are right on the money with the 4 bbl carb.-don't know much about the v6 here in particular but years ago I took the 2 bbl off a 302 Ford-replaced the intake with a 4 bbl one off a '64 Comet -put on a Holley 4 bbl -doubled my mileage on casual driving and performance(with headers-dual exhaust was amazing

Lovely engine. Sounds real nice.

Nice job great looking truck

Wow, nice project!

Wow, if that had another 2 cylinders to make it a V-8 it would be nearly 600 cid. I presume that the horsepower isn’t what it’s all about, but the torque is where it’s at. Nice clean install, thanks for the video.

Clean solid work boss

I had a 1979 GMC 2500 High Sierra that had stock smog 350/Turbo350 and 3.73 gears. Swapped in a 1967 L-68, 400 up 427 w/ Tri Power carburetors. After some tinkering with jetting, ignition timing and secondary carb springs from Holley, and a Turbo 400 w/low stall converter and shift kit, I GAINED 2 MPG, from 12 to 14, AVERAGE. That was 1981. Could probably get closer to 20 with EFI and overdrive.

Awesome truck great job sounds great too

Work of art

I have a 72 gmc in mint converted it to a 1 ton dually and I can't decide what engine I want to put in it. Love the idea of a BB v6 like this considering they make 450+ torque at idle lol. I just don't like that big of a bore. What is also interesting though is that V6 will bolt to a Alison trans just like a 496 8.1

I just bought a 1969 GMC bus 35 foot with the 478 v6 with a 5 speed manual with granny low rear engine pusher that has been converted to a motorhome in the 1990s needs some interior fixing go through the systems make sure everything is working engine needs a tune up but other than that I drove it home bought it for $2000

If you put a 6V-71 blower on that, you'd have one of the coolest trucks ever. You could run maybe 4 psi to keep from stressing the engine much and keep heat low, but still have a brutal amount of torque. Then the 3.55 gears you wanted wouldn't feel any less powerful.

Holy cow. Gorgeous.

Nice truck!

My present fuel economy is about 13-14mpg with the 4:10 rear gears. I picked up a used gear vendors overdrive unit that I will install this winter which should help improve the mileage a bit more.

Brandon Weaver. My grandfather taught me to drive,61 GMC had one of these V6 Motors stick on column. My grandmother would not ride said he drove too fast Get to the lake cabin in no time. I thought it was a strange-looking engine being around straight 6 and small V8. I have a 67c10 chevy had for 42 years often thought about and had a 440 mopar and a 455 Olds to drop in it this would be different, guess I will stay with a 67 Corvette 327 look with A6 compressor. I am proud of my truck as I am my grandparents. Always think of my grandfather in the passenger seat.

Old Jimmy sounds good.

I've always wondered about the gains from turbocharging or supercharging this family of engines. The span across the top of the piston makes me think that poor MGP is the result of the lack of any squish or swirl inducing design to mix the air/fuel charge for improved combustion efficiency. Personal history: the 351E in my family's '66 suburban produced a flat torque curve starting at 1200 RPM and returned 14 MPG on a good day.
