Jason Johnson yeah but other people need them more, usually people who can’t afford the extreme idiotic prices people will want after videos like these
@@Shade_tree_garage01 The company I work for has a GMC with dual rear axles, 5x4 transmission, air brakes and a 427 industrial engine. We were using it until about a year ago.
huge respect for the 366. I was servicing a fleet of them and they regularly hit 250000 km with no engine issues while tiring +4000 rpm down the highway and almost all those miles were highway miles. they may not be hotrod material, but they are reliable!
Absolutely, the extra ring is for the amount of stress these trucks endure moving 6 tons of payload in the dump bed. Pretty much living its life with the pedal to the floor
Another common engine in those is the 292 inline 6. My father in law has one in an 83 C10. We fuel injected it (including electronic spark control) and turbo charged it. Pretty unique I'd say.
Kristopher Klassen you might not be able to stand gm. But almost any car gm made has better styling and looks And the sbc motor is one of the top ten motors ever made of all time
something not mentioned in this video is that the crank is forged. it fits right into a standard passenger block and you have a 427. the crank is very high quality and they have the severe duty rods just a step above the car stuff
While a 366 may not be an ideal engine to get performance out of, I DO know that truck blocks were usually much thicker than their passenger car brethren and in particular those 366 blocks were hella thick. According to one rebuilder of the those engines and the book he wrote on Chevy big blocks, the 366 is capable of being bored out 125 thou. What that means in terms of bore size, or piston availability that I don't know. But it might be an interesting exercise to see if it's possible. ...or just stuff the 366 into a ratrod and call it good.
supposedly, the book mentions only boring the 427 out .125, the 366 can stand .090. I would have thought they shared a water jacket sand core to save money at the foundry. The bore is 3.935, so if sonic check said only .09 is possible, that's a 382 cid and a lot of weight since it's a tall deck block (you can put your thumb between the water pump and the bottom of the cylinder head). I guess one might try to sleeve for bigger cylinder bores, but at that point you might as well buy any aftermarket block out there and have thicker everything and roller lifter bores. The 427 was--before aftermarket blocks--the go-to for stroker Rats, since there was room for a big $2,000 billet crank and connecting rods. As far as just using the crank, I'll bet its balanced to those heavier pistons, so I think that too is about as costly as just picking up an aftermarket Chinese crank from the get-go.
@@albertgaspar627 that 366 has a monstrous amount of torque. That’s why they were used so much in the trucking Industry. It was cheaper because of the small cubic inches but torque out the Wazoo. A very unique motor. Many miles we put on one bro it out die. If I had one in my u k, I woul not want anything else. Cool motor.
@@stansmith1911 they did make torque, just like inline sixes surprisingly popular in big trucks with a numerically high rear gear ratio. Smaller displacement will result in better fuel economy on an empty truck going to a work site at a steady RPM on the highway. They will pull amazing loads up a hill, they just won't do it at great speed like modern diesels with overdrive transmissions. But a benefit of gas engines in cold temps is the fuel won't gel like diesel fuel, you just need to keep the tanks full so they won't fill with water vapour that freezes into ice overnight.
tall deck height also allows better rod to stroke ratio and the small bore allows for better air fuel mixing. Extra piston ring also is sweet and I bet there is more coolant around those cylinder walls. Can get good fuel mileage for the motor size and longevity at high load and RPM's. I never heard of that size. I have heard of the tall deck height 427's. Pretty cool. Dump trucks rule, especially Chevrolet ones.
We have a 70 GMC 5500, basically the same truck, that we put a 13 ft grain box on. It started life as a county dump truck without power steering. It's a brute to drive. 5 speed trans with 2 speed rear end and a 350 engine. NO AC except the 2/55 ac.
Bought 1 of those 427 tds years ago. Went to get it all machined up, and got talked into a swap with a 4 bolt 454 block. Sounded great, until a couple years later found a bunch of welding evidence in the water jacket. Live n learn!
A buddy has a same year C60 dumper currently under fix. Has the offered and numbers matching 327 sb in it. Also was avail with a 283ci sb. Braking systems on those are sketchy bigtime!!. DON'T LOAD HEAVY!. Complete Power steering setups are rare as hens teeth,,but they were offered and worked reasonably well. Still can get pumps and 1500psi 4gpm boxes for them. Both with a regular PS box and also a ram helper steer setup on the drag link,,and some had both,,to be able to steer the brick.
Thank you very much for answering all of my questions I have had about the 366 since I was a kid. My father had a 1970 as a wrecker. It had the 366 with a holley 4 bbl and had no guts whatsoever. I always wondered about that engine and why I never saw it in cars. Thanks!!!!!
the beauty of the 427 tall deck (spotted by the ability to slip your thumb's width between the water pump mounting and the top of the block/bottom of the cylinder head) was the ability--back in the days before aftermarket blocks--of slipping a stroker crank into that taller crankcase and clearing the cam lobes. If you didn't want to bore out a passenger block until you saw water, you went with a tall deck. And I think the crate 572 cid use a taller deck block.
Great video. Weren't these engines built at the Tonawonda engine plant in NY? Seems like I remember seeing that badge on 366 equipped trucks..... A factory I worked in 30 years ago had a large amount of paper trim from the automated dies they used to cut products out of, and they bought a 1969 GMC garbage truck to collect the trim with. It had tandem rears, and I believe the equivalent of a C-70. It had a factory 427 with a huge Holle double pumper, a hi rise cast intake and a very pleasing slightly lopey idle. That engine was a beast. It ran out in an old school power glide 2 spd. , And it shifted so hard it'd set you back in the seat hitting 2 nd. Torque was unbelievable.
Not much different from a 366 to a Detroit Diesel, roughly the same size. What makes the 366 even more rare is that they were usually stripped out for diesels anyway, much easier for PTO and packing a lot of highway miles. Noisy as hell though, as there's barely any soundproofing in old trucks like this, giving it supposedly more payload capacity.
I drove a GMC dump just like that in Late 70s, had the 4-71 in it. Boy what a beast. So much power for what we did with it. It had the 5 with 2 speed rear. I Loved that dump.
Neighbor has a 1963 c60 with a 292 straight 6. The thing is a tank. It starts right up after a few pumps on the gas pedal and easily handles anything we throw in the back. It has a 2 speed rear end and can only go 45 mph but it's incredibly useful.
I drove a water truck in the orange groves during the hot FL summers with the 366 as a kid. I never changed the oil and it idled all day. It never ran hot and always cranked in the morning.
A) My dad had a 70 C70 tractor with tall block 427. 2) A guy outside of Lisbon Ohio had put a 73 style C50ish front clip on his 4X4. Looked good with the exception of the busy paint job.
I remember riding in my uncle bobs ‘72 c50 with a straight 6. I remember once telling him “ This is a cool truck” as I picked hay out of the arm rest, and he replied “ Well it’s just a ole farm truck” and now I love 67-72 chev trucks
I remember when I was a kid all our school buses were those old chevys and fords with 366s and the fords had 370s. They both had a unique sound for sure.
From having owned a few 366 I can say without a doubt they are legendary for durability.Also many parts will interchange between 366,396,427 and 454,things like gaskets,fuel pumps and exhaust manifolds and headers.There were also later models that featured TBI which was a drastic improvement over the Carter and later Quadrajet offerings. There were also models designed to run on Propane,which of you can find one will usually be near virgin internally even if they have stacks of miles on them.
My dad use drive an old C70 dump truck with a 366, 5speed 2speed axle, single axle with a pony axle(lift axle). That truck would scale 16 tons, hauling loads after loads of asphalt a day. It was very reliable.
Cool old truck, but every DOT inspector that saw it rolling, would pull you, and go over it with a fine tooth comb. My family's excavating business had to retire a nice International dump truck for that reason. Hard to run a business from the side of the highway.
Pedro Bergamaschi Typically the front end, and brakes, but would evolve into any little thing. I'm not bashing DOT, a lot of dangerous trucks out there, and a 50 year old truck is a fair target.
Those shorty trucks also make excellent tow vehicles, both with standard hitch and a gooseneck trailer. Adjust the rear spring rates to suit and they last forever and will pull any trailer you could ever want.
Did that truck have a factory ( or dealer ) installed A/C ? seen what looked like a condenser in the front, and a pretty large heater core box,...no compressor, but people took them off all the time.
Wow, you don't see that every day on any '69 truck, let alone a medium duty commercial truck, could not have been to many made at all, who even knew it was available .
Being a Brit, my automatic reaction to a V8 commercial petrol engine is, WTF is the fuel consumption like on that thing! Nothing commercial in the UK built after the early 1950's had a petrol engine, apart from a few small vans. Even those went diesel in the 60's. Nice truck though!
That petrol engine put out diesel power, it was equal to its Detroit or Cummins counterparts, and the 427 exceeded them, with the same Milage. 12.9MPG 300HP 500FTLBS of torque
Years ago I worked for a landscape company, my work truck was a new 1994 Topkick flatbed with a 366 gasser and a 5 speed manual, it got 5mpg. It replaced the 1991 Ford F-350 stake bed with a 351 and 5 speed (the company had several of those spec trucks) which also got around 5mpg. The 366 has torque for days. It didn’t care if it was loaded or empty, pulling a skid steer or not, it just went...drinking lots of gas while doing it. The 366 would simply run away from the 351s, they just couldn’t keep up. She sounded sweet too.
I own a 89 c7000 dump truck and a 92 kodiak dump truck. Both have a 366. I haul 9 ton all over the mountains. Not speed demons but they can haul. Both of mine top out at 60-65. Very rarely have an issue.
I used to have a 69 C50 Dumper, but it had a cattle rack on it. I loaned it to a guy to haul some rocks on, and he broke the frame in half somehow while dumping. So I sold it to him for $100 (it was pretty thrashed anyway). He welded the frame back together and as far as I know still uses it.
We have one of the old TopKick dump trucks and it's a strictly propane 350ci Chevy. Absolutely crap for climbing hills, but nothing seems to be able to stop it. Also somehow manages to turn on a dime.
I had a 1978 C50 flat bed with a 350 that I bought just because it was cheap. Had to sell it. Sure do miss it! I pass these old beautys all the time working in rural areas, I just dont have anywhere to park them!
You still see quite a few of these out in my area. There's some vegetable farmers near by that run these, most have had the doors removed and the top of the cab sawzalled off and are typically driven by migrants thru the fields and such. A lot of these trucks are still in service as grain trucks. Most that come up for sale can be bought really cheap. Farmers have moved on to semis pulling hopper bottom trailers or they've gone to longer, heavier straight trucks with diesel power plants in them. Those trucks made a lot of money for a lot of guys over the years.
ih1206 exactly, back in the day these things were on every farm hauling grain. You could still get the 427td up until just a few years ago in the kodiac and top kicks.
The chevy trucks also came with the big block V6's they are so good I wish I could find one now to build up they had the plaid valve covers and looked so cool.
There are a few guys here in Spokane using these for custom trucks and they look mind-blowing. Check Rtech Fabrications to see one of these done up also with a custom made 4 door cab.
The cab trick for 4 wheel drives works on most trucks from the 50's thru the 80's from ford , chevy and dodge it was so much cheaper for auto makers to use the same cab for all of there truck models but the only ones I have ever seen used are on the big ford 4 wheel drives in florida we have it made because there street legal with 44s and they look so good with the big factory fenders.
Some of the Chevy dump trucks 67 thru 72 had a factory Tach in the center of the instrument cluster.. You can take the whole cluster out and install in a regular truck.... FYI
I love GMC and Chevy trucks. I currently have a 2000 GMC 3500HD one-ton dually with a 7.4/454 Vortec. It was the last year for the 454 and the first year for 4-wheel disc brakes. It was formerly a government vehicle and had only 42,000 original miles when I bought it last year. I have some plans for that beast.
I owned a 1975 gmc 6500 dump with a 366 it was a real good motor even with a lot of miles never leaked a drop of oil but gas milage sucked about 4 to 5 mpg was ok till gas started going up then traded it for a 7000 with a 453t wish I still had it
I have a 366 in my 40’ Blue Bird RE bus. Originally I was disappointed. But did my homework and the 366 is actually an awesome engine for its use. It’s actually pretty powerful, but even more important it can withstand abuse. Oh. Also. It moves my 25,000lb bus 75mph on the freeway. I love it!
Hey David, I like the old industrials.. I wanna make a cool race car toter... the only problem is the 2 speed rear gear is SOOOO RIDICULOUSLY LOW... like 7.10 in low and 5ish in high! Who sells a ring and pinion in like a 3.08 (for the 2 speed carrier) so I could have highway gears in high range and good in-town gear in low.... ???
You forgot about a difference in the cabs, medium/heavy truck cabs had a flat floor with no transmission tunnel. And they were all small rear windows. Even the 73-87 body style trucks had small rear windows which is really cool.
ive seen those old chevy dump trucks changed up to make them as large pickup trucks (replacing the back with something that looks like an oversized truck bed
About the only thing you could do with the tall deck blocks to make power is supercharging. But it will only ever be a low speed engine with those heavy pistons.
those trucks with 350's had forged cranks as did the 366. The headlights of T3 are the same as Camaro and worth$$ Some Farm equipment with gas engines came with HP stamped blocks as well. so if you see an engine laying around, look at the end of the crank to see if it has forging marks
o.k he stated some facts but he has misled the crowd a 427T "tall deck" has the same bore 4.250 as a standard big block and can be bored .125 over. Can easily do a 468 or 496 stroker combo 600hp street car......think about it.......yes Fry- Burger this should be your next west tech dyno budget big block build. I run a tell deck 427 in my Nova its a great engine. Back in the day before aftermarket blocks this is what drag racers were using to build bog cube torque monsters.
I kept a flock of 9 366 chevy's running for a siesmic drilling company. the used a fleet of them little chevy truckswith tandem suspentions and 5/4 trans in them. they are a super tough motor, but there was a couple guys i swear were there to prove they could destroy one.
My grandad had 3 of these 366 big blocks and he had a 427 tall deck. I want to try and dig it out to build a race stroker engine with it. I knew a guy who bored his 60 over and put a longer stroke crank and it was a monster
366/427. Engines were very common. Still lots kicking around. I have a 1980 c70 427 full tandem air brakes and air shift complete with 19 ft box and hoist only 70000 original kms.
Cool video, love these old dump trucks. I've gotta know what year Wagoneer you guys are working on? (Edit: is it the blue '63-66 I spy in the background?) I have a slightly ratty but 100% original '69 that I bet Freiburger would love. Gotta get some videos uploaded...
awesome truck my family has a 1969 chevy c50 shorty but its a tow truck and im pretty sure it has a 350 v8 in it. my grandpa bought it new in 1969 and it currently has just shy of 17,000 original miles!
Does anyone else hate the fact that he probably has forgotten more about cars than anyone of us will ever know? And by "hate", I mean I'm completely envious of his knowledge.
the point at which the cab mounts to the frame might be different than a regular pick up as I know some of the other dump trucks were different than the pick up And some of those dump trucks come with a 350 small block and it still pulled good
366 was an interesting engine, their biggest down fall was using very small exhaust valves so they were notorious for burning exhaust valves when pulling long hills when the EGTs would shoot up. But they got way better fuel mileage than the equivalent Ford model. My family has been doing dirt circle track racing since 1960, big block modified division. Back in the late 90s my uncle got a couple 366 blocks figuring they would be a good heavy in expensive alternative to finding early 427/454 blocks. After the aggravation of finding performance parts because they're completely different from other Chevy big blocks, we were disappointed to find that after only a few nights they were cracking at the crank webbing in the block, so needless to say those blocks are now just weight on the plow. I had an old 1969 C60 dump when I was doing construction I got it cheap with burned valves. I ended up swapping it with a tbi 454 never had an issue after that
Annnnnnnd the prices for medium duty trucks just went up.
o2boutdoors at least some won't get crushed
Jason Johnson yeah but other people need them more, usually people who can’t afford the extreme idiotic prices people will want after videos like these
Jason Johnson people still use these for work trucks, not show trucks.
@@Shade_tree_garage01 The company I work for has a GMC with dual rear axles, 5x4 transmission, air brakes and a 427 industrial engine. We were using it until about a year ago.

Same for the 330 found in older F-600's
I really miss when roadkill was free.. 😭 I really enjoyed your shows, but not everyone can afford it
Its cheap..
I’ve got to buy some new Mopar parts instead
Still free, just you get it 2 weeks after premium, or 2 months, i forget. Anyways, after the first year of premium they stopped charging me
you can just keep making different emails and use them to do consecutive 30 day free trials.
$45 a year dude
Another common engine in those is the 292 inline 6. My father in law has one in an 83 C10. We fuel injected it (including electronic spark control) and turbo charged it. Pretty unique I'd say.
AWLSOME!

Kristopher Klassen you might not be able to stand gm. But almost any car gm made has better styling and looks
And the sbc motor is one of the top ten motors ever made of all time
You should just restore that truck. It's a beauty.
My thoughts too, it even has A/C is seems. And great for those occasional dump runs or carrying short cars.
I thought the same thing. Pretty rare to see factory ac on these big trucks
I would ditch the bed, put a RV utility box(for tools and straps and such) and a 5th wheel on it and use it as a car hauler.
Youd better change the gear ratio and an overdrive if you wanna go distance.
Yes, don't talk about making something else out of it.
I could listen to this guy, all day long. He knows his crap inside out.

Albert Gaspar, Or just put a mild hydraulic cam in a 454 and destroy any variation of a 366...
So this motor can handle huge boost...6-71 or twin turbos.

11 years old and I learned to drive in a C60 with a 300 bushel grain box and 6.50 tires. Now find a V6 305, yes. V6
Myvintageiron7512 built one of those on his channel. Pretty cool engine.
mcinkyt they also have a 350v6 and a 4.3v8
They also had the V6 with 472 Cubic Inches
And 478 V6 GMC also had there own V8s & a V12
They put em together for the industrial/agricultural V12, some ran non stop for months non stop powering pumps and generators.

With the 427 tall deck, you can still Bore it out 100 to make a torque monster build.

Have a 366 in my 1983 C30. Sounds amazing with 3 inch straight pipe stacks
That grill is SUPERB. The individual pans for everything, double air intakes, man what a look.

A) My dad had a 70 C70 tractor with tall block 427.
2) A guy outside of Lisbon Ohio had put a 73 style C50ish front clip on his 4X4. Looked good with the exception of the busy paint job.
We used to have an old 69 fire engine in our station with a 366. Was a cool truck. Miss that thing...
Some of these c50 trucks came with large journal 327 small blocks also.
We have one.
I remember riding in my uncle bobs ‘72 c50 with a straight 6. I remember once telling him “ This is a cool truck” as I picked hay out of the arm rest, and he replied “ Well it’s just a ole farm truck” and now I love 67-72 chev trucks
I remember when I was a kid all our school buses were those old chevys and fords with 366s and the fords had 370s. They both had a unique sound for sure.
Woah, an air conditioned cab at that. A/C was still uncommon in the 1967-72 C/K10-30, almost unheard of in the C40-60.
From having owned a few 366 I can say without a doubt they are legendary for durability.Also many parts will interchange between 366,396,427 and 454,things like gaskets,fuel pumps and exhaust manifolds and headers.There were also later models that featured TBI which was a drastic improvement over the Carter and later Quadrajet offerings.
There were also models designed to run on Propane,which of you can find one will usually be near virgin internally even if they have stacks of miles on them.
My dad use drive an old C70 dump truck with a 366, 5speed 2speed axle, single axle with a pony axle(lift axle). That truck would scale 16 tons, hauling loads after loads of asphalt a day. It was very reliable.
So nice listening to someone who actually knows what they're talking about.
Just what you need around the house
I had a 366 tall deck in my square body S10 blazer mud truck in high school. It was propane powered and awesome!
Lot's of old school bus's had the same 366, and old grain trucks were also fitted with a 366. The 366 had HP, but the Torque was Awesome.
Yes I have heard of the 366 big block, I worked on many of them with my dad as a kid.
These were good old workhorse trucks. Drove a lot of them back in the early 70's hauling grain, feed and fertilizer.
Cool old truck, but every DOT inspector that saw it rolling, would pull you, and go over it with a fine tooth comb. My family's excavating business had to retire a nice International dump truck for that reason. Hard to run a business from the side of the highway.
***** Funny thing was, since it was my grandpa's truck, it got more TLC than most. It was mechanically perfect.
Man that sucks i feel sorry for you guys that live in crappy states like that. I could drive that thing all around here and no body would even care.
what's the reason for all the harrassment?
Pedro Bergamaschi Typically the front end, and brakes, but would evolve into any little thing. I'm not bashing DOT, a lot of dangerous trucks out there, and a 50 year old truck is a fair target.
it's sad to go through that with a well maintained truck
We had 60 series plow trucks at the town highway dept I worked for. All of them had the 366. It was a torgue monster.
I just did a rescue of a 1989 C7000 that use to haul around a top fuel car! It was a ton, even two tons of fun!
My uncle gave me a bunch of these.he was a school bus mechanic. He also had the 427s you speak of. We ran them in Chevy wheelers.
he didn't talk about the 702 cubic inch the V12 gasoline engine 11.5l that was in medium duty and some heavy duty trucks
comparatively..they were the exception for installations not the rule. unless you had a missle carrier ;-)
Robert haddox thats a gmc and extremely rare massive motor pretty much used only in missle carriers now the 637 v8 that was basically in semis lol
Are you sure he didn't? Go back and watch it again.
IcantSignIn he talked about the 427
Watch it once more...with feeling.
Those shorty trucks also make excellent tow vehicles, both with standard hitch and a gooseneck trailer. Adjust the rear spring rates to suit and they last forever and will pull any trailer you could ever want.
I love these heavy duty gas engines when gas was cent per gallon.
Did that truck have a factory ( or dealer ) installed A/C ? seen what looked like a condenser in the front, and a pretty large heater core box,...no compressor, but people took them off all the time.
eric wsmith I noticed that too. if I has factory air then its value just went up
Wow, you don't see that every day on any '69 truck, let alone a medium duty commercial truck, could not have been to many made at all, who even knew it was available .
Nice info but you could have add what transmission they ran and rear end and if they are usability is worth picking up for other projects
3 ton axel, 4 speed manual granny low 1st
SM465 it’s not hard
One i thought about buying has a Clark 5 speed transmission, and 2 speed rearend.
Anyone else notice the cool 2 tone international behind the brown Chevy?
Being a Brit, my automatic reaction to a V8 commercial petrol engine is, WTF is the fuel consumption like on that thing! Nothing commercial in the UK built after the early 1950's had a petrol engine, apart from a few small vans. Even those went diesel in the 60's. Nice truck though!
turboslag damn the 2500 suburban I got rid of two weeks ago had an 8.1 V8
We were getting petrol engined trucks from Ford and Bedford in New Zealand until the 70's. Maybe they exported the petrol engined ones
That petrol engine put out diesel power, it was equal to its Detroit or Cummins counterparts, and the 427 exceeded them, with the same Milage. 12.9MPG 300HP 500FTLBS of torque
Years ago I worked for a landscape company, my work truck was a new 1994 Topkick flatbed with a 366 gasser and a 5 speed manual, it got 5mpg. It replaced the 1991 Ford F-350 stake bed with a 351 and 5 speed (the company had several of those spec trucks) which also got around 5mpg.
The 366 has torque for days. It didn’t care if it was loaded or empty, pulling a skid steer or not, it just went...drinking lots of gas while doing it.
The 366 would simply run away from the 351s, they just couldn’t keep up. She sounded sweet too.
I own a 89 c7000 dump truck and a 92 kodiak dump truck. Both have a 366. I haul 9 ton all over the mountains. Not speed demons but they can haul. Both of mine top out at 60-65. Very rarely have an issue.
I used to have a 69 C50 Dumper, but it had a cattle rack on it. I loaned it to a guy to haul some rocks on, and he broke the frame in half somehow while dumping. So I sold it to him for $100 (it was pretty thrashed anyway). He welded the frame back together and as far as I know still uses it.
We have one of the old TopKick dump trucks and it's a strictly propane 350ci Chevy. Absolutely crap for climbing hills, but nothing seems to be able to stop it. Also somehow manages to turn on a dime.
I had a 1978 C50 flat bed with a 350 that I bought just because it was cheap. Had to sell it. Sure do miss it! I pass these old beautys all the time working in rural areas, I just dont have anywhere to park them!
You still see quite a few of these out in my area. There's some vegetable farmers near by that run these, most have had the doors removed and the top of the cab sawzalled off and are typically driven by migrants thru the fields and such. A lot of these trucks are still in service as grain trucks. Most that come up for sale can be bought really cheap. Farmers have moved on to semis pulling hopper bottom trailers or they've gone to longer, heavier straight trucks with diesel power plants in them. Those trucks made a lot of money for a lot of guys over the years.
ih1206 exactly, back in the day these things were on every farm hauling grain. You could still get the 427td up until just a few years ago in the kodiac and top kicks.
The chevy trucks also came with the big block V6's they are so good I wish I could find one now to build up they had the plaid valve covers and looked so cool.
I believe those were GMC only.
There are a few guys here in Spokane using these for custom trucks and they look mind-blowing. Check Rtech Fabrications to see one of these done up also with a custom made 4 door cab.
The cab trick for 4 wheel drives works on most trucks from the 50's thru the 80's from ford , chevy and dodge it was so much cheaper for auto makers to use the same cab for all of there truck models but the only ones I have ever seen used are on the big ford 4 wheel drives in florida we have it made because there street legal with 44s and they look so good with the big factory fenders.
Forgot to mention 366 and 427 td engines were also gear drive timing and the dist rotates counter clockwise. Cheers
Mr. Freiburger is so freaking cool! Buy roadkill extra guys, you know you want to!
Some of the Chevy dump trucks 67 thru 72 had a factory Tach in the center of the instrument cluster.. You can take the whole cluster out and install in a regular truck.... FYI
I love GMC and Chevy trucks. I currently have a 2000 GMC 3500HD one-ton dually with a 7.4/454 Vortec. It was the last year for the 454 and the first year for 4-wheel disc brakes. It was formerly a government vehicle and had only 42,000 original miles when I bought it last year. I have some plans for that beast.
I owned a 1975 gmc 6500 dump with a 366 it was a real good motor even with a lot of miles never leaked a drop of oil but gas milage sucked about 4 to 5 mpg was ok till gas started going up then traded it for a 7000 with a 453t wish I still had it
I have a 366 in my 40’ Blue Bird RE bus. Originally I was disappointed. But did my homework and the 366 is actually an awesome engine for its use. It’s actually pretty powerful, but even more important it can withstand abuse. Oh. Also. It moves my 25,000lb bus 75mph on the freeway. I love it!
Hey David, I like the old industrials.. I wanna make a cool race car toter... the only problem is the 2 speed rear gear is SOOOO RIDICULOUSLY LOW... like 7.10 in low and 5ish in high! Who sells a ring and pinion in like a 3.08 (for the 2 speed carrier) so I could have highway gears in high range and good in-town gear in low.... ???
You forgot about a difference in the cabs, medium/heavy truck cabs had a flat floor with no transmission tunnel. And they were all small rear windows. Even the 73-87 body style trucks had small rear windows which is really cool.
ive seen those old chevy dump trucks changed up to make them as large pickup trucks (replacing the back with something that looks like an oversized truck bed
I built a 366 truck engine, thumper cam, timing gear set, 454 intake and headers. plus a lot of other things. It's in a 69 C 10 rat rod.
About the only thing you could do with the tall deck blocks to make power is supercharging. But it will only ever be a low speed engine with those heavy pistons.
those trucks with 350's had forged cranks as did the 366. The headlights of T3 are the same as Camaro and worth$$ Some Farm equipment with gas engines came with HP stamped blocks as well. so if you see an engine laying around, look at the end of the crank to see if it has forging marks
i love that guys back yard. For the trucks and the view!
o.k he stated some facts but he has misled the crowd a 427T "tall deck" has the same bore 4.250 as a standard big block and can be bored .125 over. Can easily do a 468 or 496 stroker combo 600hp street car......think about it.......yes Fry- Burger this should be your next west tech dyno budget big block build. I run a tell deck 427 in my Nova its a great engine. Back in the day before aftermarket blocks this is what drag racers were using to build bog cube torque monsters.
One of the best Extras.
I could listen to Freiburger talk about random engine facts all day everyday.
Wish Dave would do a project with the old GMC V-6 , those were also in buses and dump trucks, good infro, great looking truck.
I kept a flock of 9 366 chevy's running for a siesmic drilling company. the used a fleet of them little chevy truckswith tandem suspentions and 5/4 trans in them. they are a super tough motor, but there was a couple guys i swear were there to prove they could destroy one.
My grandad had 3 of these 366 big blocks and he had a 427 tall deck. I want to try and dig it out to build a race stroker engine with it. I knew a guy who bored his 60 over and put a longer stroke crank and it was a monster
My 1st job as Design Engineer was at GM Truck and coach Bldg 33 in Pontiac Mi.
(Swingshift)
I always wanted to get one of these, graft a suburban body onto it and convert it to 4wd
My grandpa has a '72 GMC C60. It's just a small block, but it's still a cool truck.
Don't forget the 2 speed rear axle offered, made them a beast pulling out of a field loaded. C65/C70 were great platforms, C50 was on the light end.
I have a 1976 C65 with a 366 and the rear axle and we still fill it with corn and two full wagons behind it. Can’t stop those old V8s!
366/427. Engines were very common. Still lots kicking around. I have a 1980 c70 427 full tandem air brakes and air shift complete with 19 ft box and hoist only 70000 original kms.
Cool video, love these old dump trucks.
I've gotta know what year Wagoneer you guys are working on? (Edit: is it the blue '63-66 I spy in the background?) I have a slightly ratty but 100% original '69 that I bet Freiburger would love. Gotta get some videos uploaded...
awesome truck my family has a 1969 chevy c50 shorty but its a tow truck and im pretty sure it has a 350 v8 in it. my grandpa bought it new in 1969 and it currently has just shy of 17,000 original miles!
Does anyone else hate the fact that he probably has forgotten more about cars than anyone of us will ever know? And by "hate", I mean I'm completely envious of his knowledge.
I had a 366 in my C20 pick up truck. Was my daily for years. Got decent milage when it was geared right.
the point at which the cab mounts to the frame might be different than a regular pick up as I know some of the other dump trucks were different than the pick up And some of those dump trucks come with a 350 small block and it still pulled good
These shortbed trucks are so cool. Pitty we don't get into them in europe
366 was an interesting engine, their biggest down fall was using very small exhaust valves so they were notorious for burning exhaust valves when pulling long hills when the EGTs would shoot up. But they got way better fuel mileage than the equivalent Ford model. My family has been doing dirt circle track racing since 1960, big block modified division. Back in the late 90s my uncle got a couple 366 blocks figuring they would be a good heavy in expensive alternative to finding early 427/454 blocks. After the aggravation of finding performance parts because they're completely different from other Chevy big blocks, we were disappointed to find that after only a few nights they were cracking at the crank webbing in the block, so needless to say those blocks are now just weight on the plow. I had an old 1969 C60 dump when I was doing construction I got it cheap with burned valves. I ended up swapping it with a tbi 454 never had an issue after that
