My dad had a '79 Caprice Classic with a 350 4bbl. It would not stop! I swear that car could have been taken into combat and still survive. One of my family's longest lasting cars.
That was one of the nicest cars Chevy made
painted in the G M Good Wrench #3 colors
A camaro with a 383, high stall, big tires. Man I love that torque. The LS seems to be the best overall of today, considering price point, availability, function, mods available.
I built a 383 for my 72 Chevelle SS in 1987. Had to use the 5.565 400 rods bc they didn't have a piston design that would take the big stroke with the 5.7" 350 rod. It had TONS of torque though and would turn 6200 anyhow!!! Loved that car!!!
I built a 383 for my pulling truck, aboutpull the tongue off my car trailer!
383 in my 67 Camaro. ..
I’ve seen 383 builds and they can run pretty good, although the 377 destroker has been overlooked and from what I’ve seen they can do circles around the 383 and sound beautiful doing it, and the throttle response on a good 377 is unbeatable
@@matteblackexterior I mean, probably gonna depend on what parts are in it.. as in definitely gonna matter what parts are in it.
I am a huge fan of the original gen 1 small block Chevy. I grew up with them. I built dozens of them, from mild to wild. Daily drivers to 1000+ hp drag race engines. They are a near perfect design, and if built right, using high quality aftermarket parts, can last half a million miles. I've never built or owned one that wasn't carbureted. I don't do EFI. Period. I have zero interest in any engine with a computer connected to it. I am a mechanic, not a computer technician.
Buick was such a genius in creating the small block, that the Detroit Diesel and Olds Diesel engines borrowed the architecture from both SBC and BOP blocks! As far as early fuel injection, the OBD system was so easy to diagnose, all you needed was a paperclip. The sensors themselves only read voltage differences, so as long as the PROM chip was reading good AFR, it would set timing and fuel trim accordingly. A SBC will run on a gas can under the hood, if need be.
1000+ carburated?
No force induction?
Pass the weed
@@lop8828 it’s definitely possible. I have a customer right now having us build a small block we suspect will be close to 1000. We suspect, but have never built the combo he’s asking us to, but I think it’ll be pretty close.

And I was number 50 on your thumbs up
...I'm at 1.1 million on my 1981 chevy K10, 350 with a TH350, front seal just went, I survived the BC Floods
Thank you for sharing this. I found it very interesting. There was a time when I could rattle off all kinds of SBC trivia, but now in my late 50s, some of it has slipped my mind.
The first SBC that I ever built was a 307 in a 1969. I bought the car my senior year in high school in 1982 while working at a Shell gas station. Every one else was building 327s and 350s, but they had money that I didn't. I put a nice Crane cam inside it and a pair of Hooker headers. I also got an Edelbrock intake and used a Quadrajet carb. Everyone else was using Holley carbs, and I wanted to be different. I bought a book on tricking out Q-jets. (We didn't have the internet or CZcams then). I must have taken that carb apart a half dozen times before I got it right. After that I fell in love with Quadrajets. I finished off my 307 with an HEI distributor which was a tight fit in a Nova, followed by a GM 1 wire alternator.
True, my 307 powered Nova was not a quarter mile winner. But I enjoyed the end results because I did it all myself. The cam, headers, and intake were the only big investments. The Qjet, distributor and alternator came from wrecking yards. I drove the wheels off my Nova (figuratively speaking) for about five years before selling it. The guy who bought it didn't change a thing, he wanted to be odd like me and own a semi-built 307.
The 350 is Legend! And will be the only engine still running after the Apocalypse just ask Immortan Joe! Fury road! V8!!!!!!!
The 350 built right is tough as an anvil. What held them all back was the cylinder heads. The technology just was not there. This is what makes the LS so good. It's just an air pump, it has to breath. The LS head just keeps getting better.
5.3 were designed solely to breathe better than 350s
Henry Smith, hell yeah
I had nothin but problems 🤷♂️ But Oldsmobile and ford v8s I made plenty of and they all ran great.
Personally I don't think internal combustion engines are going anywhere. But that's me. I live in cold climate area and know the limits of batteries. It will be fun to see who actually gets it right.
A properly maintained and running internal combustion engine will start just fine in cold. Batteries are a problem. As well as starters. They make aftermarket, higher cranking capacity starters. And I've also seen people mount a second battery box in the vehicle, hooked up for double amperage. Cold affects pretty much everything metal, plastic, liquid and rubber. Electric cars will go dead faster in cold. One at least has the engine running to supply a margin of heat to the battery, as well as the alternator pushing a charge. I'm convinced that electric vehicle makers could engineer a charging system to charge electric vehicles batteries while driving. But the name of the game is to keep people dependant on big corporations. Be it big oil, coal or nuclear. It's my humble opinion that nuclear is the worst idea for producing energy. The by product from nuclear is hazardous for tens of thousands, if not hundreds of thousands of years. We STILL cannot get within 10 feet of the "elephant foot" of the Chernobyl plant melt down, for more than 10 seconds. That happened in 1986. Fukishima happened in 2014. To this day, the entire quadrant of that island is pretty much abandoned. They continue to build 100,000 gallon tanks, every day and a half, to hold contaminated water being sucked out. That's just what they can capture. The rest is going into the ocean. There's an abandoned nuclear plant on the coast of California, storing radioactive waste. There are signs posted, saying that you cannot dig, bore, build, remove or disturb the area for another 22,000 years. Until we come up with something or some way of using spent nuclear material, it is far more hazardous in the present and long run, to the world as a whole. This is just my opinion. But many others agree.
@@MNJay1 Yes, poorly maintained Nuclear power plants are a huge risk. But for a well maintained and updated one, they hold very very little risk.
Only a year later and the evs are getting solutions to most the cold weather issues it seems. You are starting to see Tesla's as a very common choice for Denver/boulder/CO springs residents who have to make the treacherous i70 commute to the ski towns often. It's because of the Awd, and the ability to run the heat for an insanely long time on a charge when crashes inevitably happen and you sit idle for hours. When I saw this it made me think it's coming ready or not :(
@@samuelriester1419 my buddy bought one in the fall. It's new and it does lose about 30 percent in winter. Loves it but does not use it for trips just as a daily to work.
@@robertbeckler5058 oh yeah I know li batteries are less efficient in the cold, I was referring to concerns that they don't work at all or aren't reliable in the cold.
the best 90's small block is the LT-1 alloy or iron heads,its a beast,and the last real small block 1955-1996
97 was the last year of the LT1/LT4. I got a LT1 in my 97' camaro😎
@@clifford_2zero7do people not know about the 1995 c4 zr1 with a refreshed LT5
@hunnterful1 The DOHC LT5 from the early 2000s is technically built by Lotus. But honestly not many people know about it. It was out only so briefly and in a rare model the ZR1 vettes of those early 90s years. 385-405hp. I hardly see any content on them I'd like to see what they're capable of modified.
@@clifford_2zero7 the new lt6 is cool for new tech but man i just want to own a late c4 zr1, people had specially made cams that produced decent power but those are 1 of 1 cams. Even if lotus did make it GM hated it because they started to discontinue parts for it.
@hunnterful1 look up the history of the LS1 and you'll realize why they never went further with anything like that.
The 350 in the 70 1/2 Z-28 was down rated 10 horse power to 360 because Corvette was the flagship performance line, so nothing that was the same cubic inches was always lower.
The beauty of the 350 is it's so simple to work on and improve with no frills.
My baby is an LS3 in a 2016 SS sedan. Looks like you forgot to discuss the 70-72 solid lifter LT-1...the best small block of the musclecar era.
My ‘72 Chevy van had a 305 with 3-on-the-tree. That engine and transmission were flawless.
My 64 Malibu has the 283/ power glide. She's not fast or powerful by today's standards but is the sweetest little engine. Smooth as silk sounds fantastic and propels the little cruiser just fine. Only other sbc I'd want in it would be a 327.
Owner of a 1996 LT4 Corvette. It's awesome.
Amen 😎😎😎
You can thank Smokey's "Best Damn Garage in Town" for the development of the first small block chevys. GOD BLESS SMOKEY.
And Grumpy !! 😁
Such awesome videos. 👌
Your spreadsheet was particularly excellent. Super clear with everything I wanted to know. Super well done! 👏 Totally with you on the IROC!
I have a 1955 Chevy with the original 265 and 2015 Corvette with the LT1. I've had 283, 327 305 and 4.8 and 325 LS engines also. I plan on keeping the 265 as long as I can.
It would be fun to port the heads on your 265 and put a aftermarket roller cam and z28 high rise style intake manifold to see how much more that would get out of it. Ram horn manifolds can flow well, so just add a turbo muffler they flow and sound good.
Amazing delivery on information. I have a 79 small-block 350 square body. After 2 g of rebuild it is almost Bulletproof. New cam intake headers and completely new electrical components for ignition. Its pushing about 330 hp rn my first build. Video. Great info.
The most underrated motor is the small block 400 it's called the monster mouse,look David Bizarre up and you will see.👍 video
Did you mean to say (David Vizard) cause I didn't really find anything on David Bizarre you spoke of.
Raced 302 in drags and 97 Vortec350 was bombproof. Great torque engine!
Great Video and thanks so much for making it!! Cheers!
Love these videos, so much knowledge 💯
The late 70s 305 was known for improperly hardened camshafts. My old man had a '77 C10, and GM paid for a cam replacement at about 40,000 miles. When I was in my teens the hot setup for "Limited Sportsman" at our local short track was a Chevelle with a 327. (Limited Sportsman cars had to be 351 CID or smaller, but there were almost no Fords.)
First, that was a fun vid! Our family cars had a 283 and 350, and I cut my gearhead teeth on SBCs in high school. They'll always have a place in my heart!
However, I noticed that while addressing the debut of the 400s you showed a picture of the 402 BBC in the truck, which was also referred to and labelled as a 400.
Great job on this video!
THANK YOU SO MUCH!!!! ALL OF THEM A GREAT MOTORS FOR ANY HOT ROD.
First time I have seen any of your vids... Excellent job linking all of this SBC history together in one story. Personally, I am not a fan of the latest electronic technologies in GM's or any other brand of engine. Coil on plug, sequential port FI ... great steps forward. Gas direct FI, variable cam timing, cylinder deactivation, stop / start... Complexity that costs more than it is worth, and potentially more troublesome over time IMHO.
I like how you said “ don’t expect an all new V8” even though GM just released the 632 lol
Excellent video - Just subscribed - Thank you!
Love these videos
Got my little 4.3L L99 up to 131 mph! Good little engine
Even the Mythbusters couldn't kill a 350.
Very well done! Thank you!!
Great Video, thanks for doing this.
I grew up on the gen 2 lt1. Awesome video here!
awesome video. learned a lot fast
The Vortec name first showed up on 4.3l SBC based V6 truck engines in the '80s and came from the swirl port head design
A comparison between the 6.2ls and 392 hemi would be sweet
Love the gen 1 and gen 2 mouse's. Whether power house, fuel miser or daily warrior they are capable of it all. Ive had 2wd pickups that got mid 20's for fuel milage and 4x4 mud trucks that squaked all 4 on the pavement. Bubble gum and duct tape to get ya home in a pinch and junkyard FULL of cheap parts.
Thank you for sharing your experience with us. The best chanal to who need learn
thank you so much for this perfect discribtion about chevy motors .... Love from IRAN to USA and General motors... your normally cars in streets is our dream in sleep🥰🥰🥰
Good video! I caught one mistake. The 70 Lt 350 did make 370 h.p. in the Corvette. But made 360 h.p. in the Camaro! The difference was the exhaust flowed better in the Vette.
This channel is great..has potential
The LT1 is a beautiful engine, too bad it's overshadowed by the LS
It's cuz LS are really cheap. Tons of people put them in everything
You can't go buy an LT1 for $600 running and swap into nearly everything with bolt on parts. That's why.
@@RodknockRhett
Don't care, I prefer the LT1
@@alexbenjaminlubbers that's what you prefer. But cost per performance is the reason why it's overshadowed.
Over course the LT1 is a beautiful engine. Things were built to be looked at back then. Not so much anymore. Though, the LS can look amazing too.
Good info 👍🏿
The 327 seemed like an engine they could have done more with. An old lady in the neighborhood used to drive this 66 Malibu coupe kinda like a gasser setup but not as high and she liked to rev it. Seemed like a peppy motor.
My mom was lucky enough to own a ‘67 camaro with the 302, mechanic gave it to her when he messed up her push button Plymouth valiant.
I liked my ‘92 z28 L98, wouldn’t have LT swapped or LS swapped it.
Best engine of the ‘90s is the LT that came in the impala
A good video. Thanks.
My friend just got a 95 c/k 1500 with a first gen Chevy small block CRATE, and the things a monster
Great video
Great video 👍👍👍
Thank you 👍
Man at the demos you know know your going to hear a 350 roaring to like 8grand one last year shot a bunch of NOS thing sounded nutty
You forgot the introduction of the roller small block v8 in I think 1987. It was still slow but at least a roller motor was kinda cool plus it switched to a 1 piece rear main seal which was a huge upgrade.
The LS is the most brilliant engine ever designed! Chevrolet took 50 years of knowledge and improved every shortcoming of the original small block and designed a bulletproof engine that just DID NOT brake or wear out. They put a special coating on the cylinder walls that just prevented any type of wear at all. I bought a 5.3 gen 3 LS1 with 220,000 miles on it and when i disassembled it it literally looked brand new inside with hone cross hatching still on the cylinder walls!!!! And putting the crank deeper into the block and 6 bolt Main caps just made it impossible to break it unless you way over rev it. If you keep the oil clean so you don't hurt the needle bearings in the lifters and rockers you could get a million miles out of one of them. You can make 900 hp without any short block upgrades! Just absolutely brilliant engineering until they started making them direct injection and compromising the valve train with lifters that bypass their pump to drop cylinders for fuel economy. Over engineering we will call that
LS1s are 5.7s
1984 305 L69 was a great motor. I loved my Z28 5 speed. 190hp rated by GM but it truly was stronger. It never ever let me down and I put 120,000 km's on it before I sold it to a friend.
190 net hp
Idk why but GM undersells their engines. I have only been disapointed with a single engine.
@@caioaugusto3138 wich one?
@@jeffcolt9185 I haven't found the name of it but it is the 1.0L (1000cc) Chevette Júnior engine. 50hp at 6900rpm. For a 900kg car
@@caioaugusto3138 thanks
Good Video
Always wanted to build a fat bore 302, got crazy power out of the fomoco 5.0 I built, be neat to compare.
The 302 is the biggest HP lier of the bunch but the 327 is probably the best street engine
The 327 was a very good engine. Good balance of usability with the spirit to get out and run. I feel it was really slighted in this video as the big part it was in development of Chevy performance. The jump up to 350 was primarily from different racing groups calling for the 355 displacement.
I will agree about the 383. That is a great all around performer also. I am surprised Chevy didn't take advantage of it. I am glad there are all the new bells and whistles to these newer motors to keep the hype up, and new motorheads involved in motorsports and auto customizing. But I am lost back in the olden dazes when you could actually see the engine parts such as heads and intake. Just more personality to the motor.
@@ronfullerton3162 the engine masters guy with the Dyno built a 475 hp 327, he is suck a good engen builder, just a career of experience.
a 360 hp 327 is vart doable with modern parts.
Good video, but there was a part carry over from old small blocks to the ls. That is the rod bearings are the same part number. The rod journal on both cracks are the same
My favorite engine will always be the 305 V8 engines they aren’t the powerhouse unlike the other SBC and BBC engines but they can have potential if they build
I exclusively build 305s, only because everyone says they aren't worth more than a boat anchor. A good friend of mine said I was wasting my money. Finished the (mild) build in my S10, took him for a ride and he couldn't stop giggling. Now it's a wild build. Forged internals, aluminum heads, sequential port efi, and 250 shot to follow. He won't be ready this time lol
As a gm tech, great video, i learned:) thanks
Glad it was helpful!
You mention the SBC that GM never sold in a vehicle... the 383 stroker. The crate engne GM Performance sells is even better than the original home grown recipe. With no need to do a .030 over bore, and no leftover 400 cast cranks needing smaller main journals, they come with 4.0 bores, forged 3.80 stroke cranks, and a new block castings that already has rod clearance.
Great job! Heard recently the Camaro is being discontinued to free up resources for the E transformation. Sad news indeed.
And dodges charger and challenger ffs kill me already
Hey I got a 1988 Corvette. Now I’m a bit happy I got the best of the L98s
FYI - the 283 was available in all cars in 57. The FI version made 283 hp
I'm definitely a true small block man. The L s they claim makes a good drag but I don't see it. My biggest problem with the Ls is it's harder for me to work on have to pull the heads to change cam or lifters and oil pump is harder to get out. But that's just my opinion the Ls I guess is a good engine but I just like the older small blocks. Very good video sir
Well done, thanks. L & S
I like the graphics, but I have a suggestion. As they were passing by I did not know which you were talking about. Perhaps having some kind of indicator or something? I wasn't sure what I was supposed to be looking at. But, definitely some fantastic information. Thumbs up.
Great suggestion! I thought of that but decided it would have been too hard to do. Im still learning how to edit these videos : (
@@AutoGuild Great job on the vid. I hear you. I'm trying to get going on some vids, it's hard work. I like something called ASMR on CZcams (basically people making soft nice sounds) and I support several people who do that via patreon and CZcams. I talked with one ASMR artist who's been doing it for years. I asked her if it got easier with producing videos. She said, "no. It gets more difficult the better you become at it." That's a bummer, but at least I know what I'm facing. Her videos have become very good, but, in order for her to create that kind of quality, she has to do a lot of video work to do it.
Me and my dad put a 305 in my 1972 Chevrolet Custom 10 truck 9 years ago and we got it out of a 1969 Chevy truck it feels like its making more power and torque than a stock engine.
In 1967 I worked at a Pontiac store and one of the mechanics (Gary Seals) had a 65 Impala SS he bought new from Quality Chevy in Wichita.. I saw the engine under the hood as he was working on it and asked him if the motor stickers on the valve covers were real. He made it clear they were indeed real. It was a 327 motor with 425 horsepower on the sticker. 425! No one has ever talked about this motor I have ever seen. I did see motor stickers for sale at some aftermarket parts company in the early 80s that showed a 425HP 327 sticker, but I have never seen it again. Have you ever heard about this motor?
I had an 89 RS five speed, T-Top Camaro, sans mufflers. I miss it and want one again.
This is excellent content. Well done Sir. However, where is the Chevy Big Block version of this video? I can't wait to see it! And I know it will be excellent.
i had an ls1 2 3 all great. still have an hci ls2. i also have an lt4.
If it wasn't for the valve drop problem i would say the ls7 is the best engine ever made
please do a story on the 637 big black Chevy GM me back in the day that went into irrigation pumps or big trucks I'd like to hear that story my friend thank you wonderfully for this one
Hey man I love the video but an engine was missed. In 2004-2006 Chevy released a supercharged protec v8 in a limited edition Silverado, and Tahoe. It’s the Joe Gibbs Edition.
Can you please do this but with the big blocks. Thanks
My 383 rotating assembly needs to get back from the machine shop time now. It's the last part I'm waiting on. 86 IROC 383 forged everything with a TKX and hit of the juice.
imagine being in a remote location with your truck and needing to start your generator and fill it with gas to recharge your truck in the middle of nowhere
Old news now but ford does produce the 7.3 Godzilla truck engine offered to date. You mentioned that domestic car companies had no plans to produce any new version v8s.
The tunnel at 7:20 is looking mighty scary. . !!!!
Cadillac had the flathead Monoblock V8s in the late 30s into the 40s as well.
Actually GM's first V8 was the Northway V8 (1916-1923) used in Oldsmobile and Cadillac. Cadillac also offered V12 and V16 engines back then. The '55 Small Block was GM's 2nd V8. and a huge improvement over Fords Y-Block (1954) which was a kluge of design flaws.
The 400 V8 had siamiesed bores which necessitated the additional steam holes and limited compression as the 1/8" bore gap made for a weak spot in the head gasket.
MAYBE YOU WOULD ANSWER ME AS TO THE LS-7 Motor. For instance what is the bore, stroke, piston compression and are the aluminum heads ported and cc'd to perfection and maximum HP? I've heard it called a 427 cu small block. That would mean to me a 4.125 bore and probably a 4.00 or 4.125 or 4.250 stroke. How does the Z06 get over 550 HP if not just the way I explained it?
My 84 camaro has a new gm goodwrench 350 I bought in 2018 and it has 200hp. My kids think its fast cause its loud and my 700r4 shifts tight. My 2010 pathfinder with a v6 makes 260hp and when I raced them they are even through gears 1 and 2 in my camaro then the pathfinder leaves me. However I will always love my camaro more thats why 3 of my 5 kids have a 3rd gen camaro.
I’m new in this.
I have a 73 Nova n im looking to upgrade motor to prevent oil leaks., n get more power n enjoy the drive every time I drive it. What do you recommend. ???
your torque rating for the lg4 305 is incorrect, its was around 230-240 ft/lbs
Never mentioned the LT5? Dual overhead cam with 500 ish factory ponies if I remember correctly
Good point, I do mention in my LS vs LT video tho!
@@AutoGuild I think he's talking about the 90s lt5 from the zr1s that Lotus help build I believe.
Being you put the built 383 in there that gm really didn't build. I'd have added the sb2,sb2.2,ro7 that gm actually built for the Nascar series.
The future is electrically driven, fully automated driverless egg-shaped pods. Ownership may make little sense too with services like Uber and Lyft. The upside is they will likely travel at 100+ mph outside of major metro areas.
The engine in the Chevy D series was also a flat plane crankshaft
Did not know that!
About 10 years ago I bought a 92 corvette LT1 I picked that car because it had decent HP and torque not great but I don't drive radical and as long as it looks mean and sounds mean I'm happy but the great thing about it the average Joe backyarder can still work on it once you start with the LS's things get complicated.
lot of LT4 motors for the C4s were underrated to avoid ruining the hype for the LS1 in the C5. A lot of LT4s make more than the LS1
Solid lifter cam in the LT-1 great engine
I have 1996 chevrolet silverado 5.7 aka 350 engine the first year of the 350 came out as vortex 350 but also in 94 they made v6 vortec in those years gm experimented with the 350 vortec to make the new ls technology for the new block gen engine
1979 Cadillac Coupe Deville, had a 425ci small block.
The Cadillac 425 was a big block. It was actually the broadest bore spacing of all GM big blocks, at five inches. The same design included the 472 and 500 and even the later 368. And then it was gone.
please make video for c8 zo6
Best engine’s ever.
Can you do this but with duramaxs?
Where is the poster link?
I know this is a 2 year old video but could you update with the 8.1 from I believe 97-06 not sure. Thanks. Great vids
