[@jaden.sanderson]

Don't forget about the 4.3 V6. It is based off of the 350 Small block with 2 less cylinders. They still use it in the GM trucks and vans today.

[@kylec.5462]

Jaden Sanderson nope not the Vans that ended I'm 2014 with the cancellation of the 1500 express/Savanna

[@jaden.sanderson]

Kyle C. Are you sure? It is still an available option on the Chevrolet and GMC website for the 2018 model year.

[@dakotamcatee2807]

I think the new 4.3 is based off of the LS motors

[@jaden.sanderson]

Dakota McAtee Yes, the 2014-current 4.3 is based of of the LT1 from the Corvette and Camaro, as well as the 6.2L from the Pickups.

[@berys76]

Also buick grand national i think

[@the_frankc]

Do the GM big block next! The 427, 454, 496, and the monster 572

[@BIGBLOCK5022006]

Frank Cucunato And the 502.

[@the_frankc]

BIGBLOCK5022006 I did forgot about the 502. Yeah that's a good one as well

[@bobnixon4015]

You stove bolt idiots don't even know there was an original big block OHV chevy starting in 1958 with the 348, 409, 427 family. Ford windsor was lighter and smaller with same power.

[@truckandtractorgarage740]

dont forget the tall deck 366 and 427 v8s

[@philtripe]

the monster motors are a completely different block...the GM big blocks started with the 366 which was found in dump trucks and school buses back in the day

[@michaelvalentine782]

Those 350's are still going to work every day! The fire deptartment here has two brush trucks with them. I know of at least one tow truck working in the area and several landscaping, and snow plow trucks still rocking 350's!

[@superdupergrover9857]

the biggest advantage to the small-block chevy engine is the fact that it is common. a consequence of this is that parts, especially performance parts, are common and inexpensive. the average american auto parts store has many parts for this engine, even things that are rarely if ever kept in stock for anything else, like performance intake manifolds, performance carburetors, etc..

[@GTX1123]

Back in the 70's it was usually easier and cheaper to get more HP out of a Chevy small block than a Ford or Mopar. While the Mopar 340 and Ford's Cleveland motors were comparable to Chevy small blocks in HP, there just weren't as many of the better Ford and Mopar small block packages made. There were a ton of Chevy 283, 302, 307, 327, 350 motors that were made - especially the 283 and 350 motors, and the parts were plentiful and all interchangeable.

[@Shawn_the_Protogen]

The Small Blocks and LS engines, such a beautiful sound they produce.

[@patrickrolf482]

Heads up they still build the legendary 5.7 small block it’s in practically every boat application inboard outboard that you see in the water today.

[@rotatingglasssafe]

Excellent video. I love it when you do these engine series. Keep it up 😊

[@tjsMAR]

Always been a Ford guy, but GM did know how to build reliable, powerful engines in their hay-day

[@tomashton1781]

the 307 was a 283 bore with a small journal 327 crank, the 4 inch wide blocks were designed to go 302 327 and 350, by changing the crank throw with the same 5.7 connecting rod, as the stroke was increased the piston pin bore was raised

[@philipfox2.081]

3 days left till Happy Bald eagles day, A nice way to start the countdown with this vid

[@SamFBM]

hell yeah brother

[@wargames8503]

VisioRacer is from Slovakia, just like me. That means he is from eastern Europe. So I don't think that he is celebrating anything.

[@aussieausdeutschland4245]

[@alexstromberg7696]

[@philipfox2.081]

Alex Strömberg yeah 19 people doesn't give a fuck about your comment too

[@silicon212]

The LT5 engine was never based on the small block. It was a special one-off engine designed by Lotus and assembled by Mercury Marine. It had a 3.9" bore and a 3.66" stroke. It also had a two piece aluminum block and no provision whatsoever for a cam in block setup.

[@iliaslamari7315]

If you maintained that good old small block Chevy well, than it will keep running for a long time. Gets almost decent fuel economy and has loads of torque. Man, it just hurts me if I see what GM is doing these days. Making all those garbage SUV's and Opel copies with Buick. I know that time is changed, but could GM make one engine again that has some power and doesn't blow up afther a 100.000 miles?

[@UndeadPorcupine]

Literally the LS series, my dude

[@NuclearGrizzly]

The small block in my '72 pickup was running funny. So I hit it with a shovel. Now she's purring like a kitten :-)

[@EL-gu1oy]

My 5.3 sierra just hit 400,000 miles and ive only had to replace a water pump and an alternator, my dads 350 which he took very good care of only got up to 300,000 then it decided to spin a bearing

[@5ohh112]

NuclearGrizzly 😂😂😂😂Lmao you are Jeremy Clarkson of US, but instead of hammer there's shovel 😄

[@dukecraig2402]

NuclearGrizzly Did it hurt the shovel?

[@kimmer6]

A year ago I bought a brand new long block crate 350 engine for my 1989 2500 van for $1500. It came minus the Throttle body, starter, and ignition wires. What a deal. Free delivery, too. It gets better mileage than the 305 that I took out.

[@jefflee1189]

kimmer6 I buy all car parts off eBay. I can get OEM parts and I often get OEM far below retail. One time I got an OEM o2 sensor for about five or six bucks

[@Kenny370]

The 350s have such a distinct sound it's easy to tell 350s apart from the others

[@13bgunbunny42]

Back in the day (I'm 56 btw) I had a '65 Chevy C10 with a 1 barrel Hi-Torque 283 and 3 speed manual on the column. Best damn pickup I've ever owned. :-)

[@robakagyser2300]

You left out two small lock Chevy engines, the 262 V8 (4.3 L) and the 267 V8 (4.4 L). The are sometimes refered to as "mini mouse" engines, which were designed and built with efficiency in mind.

[@Bigjoedo66]

Very good video full of great information thanks!!

[@deepdiamond5045]

Thanks for the info,as always,ur the best!!!

[@Roostah52]

Chevrolet Performance also still sells brand new small blocks in many diffrent power and trim levels today.

[@Toolaholic7]

Some go in the older Ford hot rods and street rods called Ford tough with Chevy stuff

[@Kstang09]

Yes they do, moron. Ever heard of GM Performance Div?? lol.

No Cheers? Im sad :(

[@victordiez2085]

Great video man thanks

[@upsidedowndog1256]

In America we got to play with these as kids. That was the old days. Now they make garbage. My favorite small block is the 400 block with a 350 crankshaft. 377 cubic inches, wide bore short stroke so it revs to the moon!

[@julianneale6128]

upside downdog it's funny because as I was watching this video I was thinking of asking in the comments what would the biggest bore to shortest stroke, so it can reve to high rpm...

[@upsidedowndog1256]

Julian Neale They truly are a badass combo. 327 also revs pretty good. 327 block with 283 crank also rev good but not much torque. I think it is the 302 Trans Am combo. 305 is worthless for power. Its hard to beat a stock 350 as is but where I live all the old small block Chevys got used up going in circles on a dirt track.

[@finharms9439]

upside downdog yea sounds like a good combo... if i ever do a chevy project(which is doubtful) i might just consider that

[@LChem1]

So right! Putting a 400 crank in a 350 is not the way to make hp

[@upsidedowndog1256]

Purr Cat 383 combo makes pretty good torque.

[@Recogru]

1:48 He has a bad distributor O-ring

[@omarramirez9200]

Im so glad you included the SBC 302ci =3

[@jlopez97122]

Love the sound at 5:24! Headers, no cat & what looks like a pair of magnaflow mufflers? Would love this setup on my c1500.

[@iwannapoop]

I'm a small block fan boy!! Everyone wants the LS, so small blocks are super cheap now. With the right parts a 4 bolt, single rear seal motor can make a reliable boosted 500 hp daily driver with a mild cam and very conservative timing. The architecture is modular for the most part (906 castings) and fit in just any GM vehicle. Actually they are si small you can fit one in a MIATA!!

[@JRWperformance]

History of the rotary would be cool. Neat videos.

[@fleetwin1]

Great engines for sure, the guys in the videos had cool nikes and asics also...

[@MidnightMechanic]

The small block never died, in fact Mr. Goodwrench were still casting blocks all the way up to 2014, last I heard. Short blocks are still widely available brand new.

[@apismellifera1000]

That was really cool now you need to do one with Ford engines and another with Chrysler engines. Keep up the good work.

[@dumper87]

Actually, the series is still in production. Brand new shortblocks and longblocks are being churned out for GM in Mexico, for sale to DIY'ers.

[@hollowell427]

You forgot the 307ci that had a 3.875 inch bore with a 3.25 inch stroke.

[@davidredfearn664]

I noticed that some of these examples had Elkhorn exhaust manifolds which we're almost as good as having headers.

[@Raycolorido]

Nice video as always

[@doctoredable]

I recently purchased a 5.7 liter factory built long block engine from general motors marine. It is the same small block 4 bolt main seal engine that has been in use for decades but has a roller cam and roller rockers making it a small block VORTEC for marine application. It is fueled with a multiport fuel injection system with high and low pressure electronic fuel pumps attached to the engine. The engine produces 320 hp and 320 ftpounds or torque at 5K rpm. It is a fantastic gasoline marine engine. This V8 engine is as bullet proof as it gets. I have placed 3 of them in my boat over the past 20 years. The first one was 260 HP with a single 4 barrel carberator. The second one was 280 hp with a throttle body fuel injection system. The one recently placed is a beast of an engine.

[@appalachigoontactical]

He said its no longer in production, that is true, but what about all of the crate motors that chevy still makes

[@xekret]

Nothing like a classic 350. Still have one in my truck but will swap an LS at some point.

[@enginenut4318]

1917-1918 was the first Chevrolet v8 overhead valves

[@Lee01Mr]

I work with these engines every day. I restore and maintain old and new GM cars

[@philtripe]

your like the guy in the 1970's that worked on steam engines

[@Lee01Mr]

stickloaf a bit like that lol. I'm in my 30's but I got brought up the old school way :)

[@dylanzrim1011]

Could have mentioned that the LS series is the small block's successor.

[@Toolaholic7]

The 4.8,5.3,6.0 and 6.2 are not considered LS engines.They are based off the LS engines with a cast iron block

[@aussieausdeutschland4245]

MASON WINKLER not just the Vettes. The Commodore also had them from 2000 till the end of Australian production in 2017.

[@turbolq4]

MASON WINKLER The true LS engines are all aluminum block and heads. There are some aluminum block 5.3, 6.0, and 6.2 engines as well. When people refer to the LS engine, they mean the whole family which includes the iron truck blocks as well. With a few exceptions all the parts interchange between them. They are one in the same.

[@nathanreimer1296]

Walter Frederick they are considered ls since they share basically everything. The iron blocks are even preffered due to being more durable.

[@violentmetalhead]

Walter Frederick Since when? GM says they are a LS right in their performance catalog.

[@shaunhuggins]

You should do the BMC A Series engine next!

[@00jeepxj61]

Got to love the 400 sbc. Siamese cylinders not withstanding it was a great all around engine. Punch it 30 over, give it a mild cam and a decent intake and carb and it was a stump pulling power house as long and you kept her cool.

[@Toolaholic7]

Lot of the race car builders buy the stronger Dart 400 blocks.

[@johnnyhawkins43]

Yes I love the old ones,also got a newer version the 5.3all of them good!!!!!

[@danielginther4879]

You missed the 262 built in 75/75 and the derated 307 budget engine both part of the standard sbc family

[@mikedodd9294]

Have a 350 5.7 from Mercruiser in my boat, all GM engines, same with Volvo marine engines!

[@colebauer5999]

Cars/packages you could get with nitrous when bought. One was the saleen focus maybe you could do a vid with more?

[@finharms9439]

Funny how the ford 302 is still around but it doesn’t get the praise that the SBC does... the 5.0 ford is IMO easier to tune considering you don’t have to lean on a chair to adjust the ignition timing... however the GM is still cheaper and a reliable powerplant.. just a Ford guy at heart thats all lol

[@aaroncone6778]

You forgot one, which was the 307. Was a durable engine!

[@Toolaholic7]

It was not,lot of them did not hold up

[@georgeross7145]

Fondly remembered as "old butter cranks"

[@CirocObama.94]

Chevy 307 wasnt reliable but Oldsmobiles 307 was neither was Chevy 305 those things were trash

[@yeahimere9631]

Aaron Cone. 307s had a nasty habit of destroying their cam shafts and lifters.

[@kimmer6]

A 307 was a 283 block with a 327 crank. 3-7/8 bore, 3.25 stroke.

[@Bennett8187]

Those are stock hp numbers. With a little tuning you could make them have a shit load more power.

[@oscarzt1652]

6:24 those sharp turns must kill torque and power?

My 350 makes 550hp, revs to 8000. It's easy to get 550hp, it really doesn't cost any more than building a good RV, etc motor.

[@theeoddments960]

I’ve seen 383 strokers make 620 horsepower naturally aspirated.

[@nordic5490]

long duration cam means poor bottom end torque and drivability. Also, high lift, high revving push rod engines have poor durabilty. 4V DHOC VVT is the path to performance and durabilty, aka nearly every other engine made in the world today.

[@andrewmayer2443]

My dad had a Z28 RS with an NA 383 stroker. That car definitely had more than 600 hp. Spun the tires in 4th gear.

[@nordic5490]

Andrew, to spin your tyres in 4th with only 600hp means they are some terrible siht tyres. I drive a turbo barra and these make 900hp with stock internals (needs valve springs) and I typically have mine set for about 750hp as my daily drive as thats about the limit of the factory spings before float. Quiet with strong midrange torque. I am doing this with stock cams and exhaust plus high flow cat, and is very quiet. V8s ? meh.

[@andrewmayer2443]

it had BF Goodrich tires, like the ones you'd typically see on a muscle cars. Yeah, pretty bad

[@nathanreimer1296]

Vortec are small blocks. They use LS architecture which are also small blocks.

[@silicon212]

@@nathanreimer1296 Vortec is a brand trademark owned by GM, first used in 1985 with the then-new 4.3 liter swirl port V6 engine used in trucks. It was used for those V6 engines as well as gen 1 small blocks and the newer LS engines. The Gen 1 Vortec heads use the port configuration and combustion chamber design used in the cast iron "Caprice" reverse flow LT1 of 1994.

[@Ratzfourtyfour]

I''d be a little reluctant to call a 400 cui engine a small block tho.

[@silicon212]

It absolutely is a small block. It uses the same cylinder heads as the 350s assembled alongside them. The only difference are the presence of steam holes drilled to compensate for the heating issues that came with the siamese bores. It uses the same valve covers, oil pan, intake manifold, fuel pump, timing cover, water pump, engine mounts and whatnot as any other small block.

@Original Hunter. What a coincident to see you here lol

[@theeoddments960]

370 hp was super underrated for the z28. It wouldn’t make sense that 11:1 compression and the cam dimensions they were running only made that. You can make way more with way less radical equipment and that’s counting the vintage barbaric tech. I know cam grinds are better and more refined but that sucker was making something like 420 horse back then. You can just tell by the rpms if you look up a video of that specific engine.

[@seth094978]

Didn't the ZL1 have an aluminum 427? Did you mean Z/28? I've read that L88 powered '69 Corvettes and ZL1 Camaros were making upwards of 540HP (435 advertised).

[@theeoddments960]

seth094978 um... there were more years for the zr1 besides 68-70. But yes, I did mix some numbers up. My mistake. And yes I was talking about the 350 camaro, as the engine was very underrated.

[@theeoddments960]

MASON WINKLER Yes, and Chevrolet was the one who did it the least the make it appear that they were still superior to the pack. The l88 was a great example since that car was rated at 430 horsepower, but was really making upwards of 530+.

[@theeoddments960]

I will admit I did mix up rpo codes and will edit promptly.

[@Nightfall_zv]

@@theeoddments960 zl1 was only in 1969. 69 zl1 camaros were made and only 2 corvettes were made. The l88 corvette was made from 1967-1969. The z28 with the 350 you’re referring too is the lt-1. They came in the z28 camaro and in the corvette. They were listed at 360hp in the camaro and 370 in the vette. Same engine just listed differently. But yes all them engines in reality made way more hp then they were listed. For insurance purposes

[@evanleo7633]

i think new LS and LT engines are still small block

[@ThePgR777]

Small block a 4,3 liters V8 ? Small block here in Europe is 1.0L 3 cylinders turbo

[@andyharman3022]

I suppose it does a great job powering your blender when you make a milkshake.

[@seth094978]

It has more to do with the configuration the block than the actual displacement. The smallest big blocks were like 5.7L and the biggest small blocks were like 6.6L. Also, saying small block V8 is kind of like saying small mansion, it's still going to be pretty big.

[@efcodpalama]

Because pushrod engines package so efficiently, even a 6.0L small block will be very small on the outside. For example, an LS7 7.0L engine is barely bigger on the outside (and almost exactly the same weight) than a Mazda 1.8L DOHC b series.

[@TewChainsaw]

haha; GM 292: 4.8L / straight-6

[@Elandycamino]

Really wanted to watch this until I heard this guy's voice🤣😮 WTF

[@Piotr94L]

What about SB2.2?

[@andyharman3022]

The SB2 was a variant of the classic Chevy small block designed for racing. The major difference was the mirror image arrangement of the cylinder head ports. Traditional was eiieeiie. SB2 was ieieeiei. This change required different pistons, camshaft, intake manifold, and exhaust headers.

[@silicon212]

Purely a race engine, never installed in any factory vehicle. The SB2.2 was a NASCAR Winston Cup engine.

[@philtripe]

one small block chevy motor can put out one million pounds of co2 in its lifetime and thats for a modern engine with emissions controls

[@chrisyarber3352]

stickloaf who cares

[@beniamino939]

The small block 350 has such a short stroke to bore ratio. That's the downfall of it's bottom end capabilities.

[@marccadec6978]

Some very under powered engines in regards to the displacements.

[@philtripe]

back then many cars had 6 cylinder engines with 70- 90 hp. this was a long time ago

[@Redlineshadow29]

Very interesting. I have a question. What is the diference of ci for cc??? Then, what units of small block chevrolet is actually used for drag racing modifing with nitrous, turbo, procharger or a blower??? And what is more capable of it??? Then if you can do the same with big block and motors with be able to modified to drag racing, that's better

[@andyharman3022]

1000 cc = 61 ci

[@Redlineshadow29]

Andy Harman thanks for the 1st question

[@ilovemanunited6179]

So do DOHCs increase power, because a lot of DOHC engines seem to have more power compared to counterparts.

[@kevinsmith1369]

DOHCs allow the engine to run at higher rpms generally so thats where some of that extra power is coming from

[@Epotheros]

They generally do, but they also greatly double the size and weight of the engines. If you noticed how small these engines looked in this video, it is because they are all OHV engines so they don't have the cams on top. A good example of this idea is the 7.0L OHV LS7 being about the same size and weight as a 3.5L DOHC V6 from a Camry.

[@silicon212]

Jury is really out on OHV (pushrod) vs. OHC engines. They both have their advantages and disadvantages. OHC advantage? Less valve float at high RPM due to less moving mass between the cam and valve. Less complexity for more exotic designs such as 3 or 4 valve/cyl engines. OHC disadvantage: Size and weight. Put a Ford 4.6 mod motor next to an SBC and you'll see. OHV engines are smaller and lighter, but are generally limited to 2 valve/cyl designs due to complexity and valvetrain geometry. For everyone who says that pushrod engines are susceptible to timing anomalies such as pushrod elasticity at high RPM, I'd like to remind them that the super long timing chains used in OHC designs are more susceptible to stretch at high RPM, leading to the same types of anomalies. Also, timing belt driven OHC engines can suffer catastrophic damage when a belt fails, which happens considerably more often than with a chain drive.

I hated the 305, why, because of all that emissions BS and trust me it killed the motor no matter how you treated it. Knocking pistons and almost no horse power the poor truck we had may have done a lot but not enough to cause its problems.

[@chev555]

grumpy chuck thegrumpychuckchannel yep, I tore out all of the emissions bs and even on 7 cylinders it ran so much better. Now I have proper headers on it, and edelbrock 650, and am getting new heads pretty soon possibly since the valvetrain is around 30 years old now. But I don't know, I may just sell the thing and cut my losses and go for an mr2 or something.

[@TheGrumpyChuckChannel]

Unfortunately we sold the truck then it got scrapped. Not the first time its happened.

[@silicon212]

A 305 with the proper cam, headers and a set of World S/R Torquer 305 heads (no longer made) is capable of over 300 ft. lb torque and north of 300 horsepower. The factory version was purely an economy/smog engine. You can still get them for next to nothing and then build something to rival any other engine.

[@doctorclaw8232]

I have never been able to find an aluminium block of these, only LS

[@Recogru]

They never made one from the factory. You can find them brand new from the aftermarket for around $4,000 to $6000 US

[@doctorclaw8232]

I know that, I want to know who sells these blocks?

[@doctorclaw8232]

Lightweight and better cooling for a Fiero, the only blocks there is are from shady brands

[@Kstang09]

Mason you're just full of all sorts of misinformation today! DART & Brodix both make aluminum blocks that very much out perform any iron variant from the factory. Oh, and MUCH lighter. Lay off on the stupid pills, dude.

[@Kstang09]

Stay #triggered there, mason ol' boy! If I were half as crazy as you I'd write a book about it, something about iron blocks being more desirable. It's the weekend, enjoy your day drinking ;)

[@muhammadaimannazruddin7622]

All these are very large compared to japanese 4banger..

[@christopherohara9421]

SBC rules

[@Toolaholic7]

The last one mentioned,was built and designed by Mercury Marine and not by Lotus.Can't get parts for it anymore.The 265 never came with an oil filter from the factory.There was the 307 also,it was an alright engine at the time.They are also popular dropping in the older Ford hot rods and street rods.Advantages are parts interchange,dirt cheap to build and easier to get parts for over the small block Fords

[@andyharman3022]

No, the LT5 was designed by Lotus, and manufactured by Mercury Marine.

[@Toolaholic7]

The parts for that one are obsolete,heard this from guys that worked on them.

[@silicon212]

The 265 indeed got an oil filter for 1956. Just the first year ones didn't have that on the block, but was a dealer option (remotely mounted).

[@infernoking7504]

Gm products now a days are garbage compared to the old days well they still aren't good

[@903strikerunit]

Pardon my ignorance good folk But aren't most US made v8 all share the same layout? (OHV 90 degree v8) So what makes the GM engine unique other than it's production run and age? Isn't the LS motor more iconic? Or the dohc NASCAR engine built by was it Chevrolet?

[@00jeepxj61]

firing order, build components, and the design of how everything worked together helped to make the sbc ( small block chevy ) a mainstay in the auto world. Each manufacture did things similar but different in a lot of ways. The LS motor was it's own little world and continues to be in a lot of different circles. It was one of the first of the "computer" controlled and operated sbc if I remember right. I also made good power compared to the previous years of emission choked power levels. Going from 170 hp to 200 hp on a engine displacing 5.7 or 350 cubic inches doesn't seem like a lot but it's enough.

[@dylanzrim1011]

MASON WINKLER the 351 ford although not overly small. Is king lol

[@Recogru]

It was one of the most widely used V8 engines in the US and the one that most hot rodders used in modifying cars. Very easy to find parts for. A very large selection of modification parts. Very cheap to build and modify. A basic rebuild kit with new gaskets, bearings, seals, pistons, camshaft, oil pump, timing chain, and lifters can be found for less than $200 US. They are simple to build and can be torn down, inspected, and reassembled in an afternoon by one person. With a set of decent cylinder heads that can be found for around $600, an aftermarket intake, and a hot camshaft they are easily capable of 400-500 hp. Most can be built to that level of naturally aspirated power for under $1500, sometimes less then $1000 if you look for deals on parts. With some factory cylinder heads some time can be spent with a die grinder and sanding cones to port the heads, and builds over 450hp with a good cam and intake is not unheard of from a set of ported heads.

[@dylanzrim1011]

MASON WINKLER the Windsor/Cleveland held world records, granted it didn't have as many aftermarket options and it might not have had as high numbers when built. But stock vs stock? I still regard it as king.

[@boggy7665]

The 'small block chevy' was relatively compact and light weight for its era and power output.

[@alexlozada1939]

I try to like it but I just can't,it's not the same, Ford is the original Don dada 💯 FORD V8 💯💪❤️ 4Ever.....
