Don't forget the 327
And the 307, and the 400
That 327 made a lot of HP
@@oldsguy354 The 400 was actually 401 in cubic inches.
@@Olds_Pwr Yep, 400.9 inches according to my books. I wonder why they didn't advertise it as a 401. Maybe they didn't want it to be confused with the Buick or AMC 401's. I know the Olds 403 got rounded up from 402.5 and it along with the Chevy small block 400 had siamese cylinders. I think they were the only GM engines that were outfitted with that unique liability, which was especially troubling on the Oldsmobile because they had to leave alot of expansion room for those gigantic 4.351" pistons. I know hindsight is 20/20 but skipping water jackets between the cylinders to make room for a ridiculously oversized piston bore probably wasn't the smartest engineering decision they could have made. I can almost hear the discussion at the planning meeting for that, "Here's my idea, let's take a small block and bore it so large that the engine displaces 50 more inches than it was designed to so it makes a ton more heat. Then we can reduce its cooling efficiency by 20%, and use the same lower end designed for much smaller engines and put the largest piston bore we've ever used on top of it. Once we get it to meet emission standards we'll enjoy a whopping 10 horsepower gain on a car that barely gets double digit gas mileage! What could possibly go wrong?"
And the 262, 302,and 307. And yes there was a 302 chevy. It was offered as an option so chevy could compete in the trans am series.
They forgot all about the 302 that was just an animal
-That ain't a chevy small block though.-
Well, shit. Learned somethin' new today. Thanks.
They were pretty nasty small blocks for what they were
Had one in a 66 deuce. One bad mf'er
Destroke a 400 with a 350 crank put 6"rods in it and think of it as the larger version of a 302 with the same rpm characteristics with 70+ more Cubic inches.....that's makes a nasty small block!
Your mom was just an animal
The 305 dominated the driveway .
You can get 400+ HP from one if you sink enough money into them. I wouldn't, but you can.
@@LionWithTheLamb you could get more with forced induction, i still wouldnt either, but you can lol
They also dominated the drive-thru. 😂

It was appreciated for its compactness for an OHV engine when it debuted.
now look at the size of an LS compared to a 350. unreal how much power comes out of such a small footprint

and no power
@@678friedbed well no shit. Lol
I mean they are kinda reliable if you just drive around as a daily and don’t get them hot. But you get them hot and it’s all over
Yeah got a 350ci 5.7 and idk a lot about engine classification when it comes to blocks but it’s not that small. What does small block mean?
@@illegalpoptart9633 Small block just refers to the external dimensions of the engine. In the 40s and 50s, all manufacturers made small block and big block v8s. Small blocks were for cars, big blocks were for trucks and didn't really fit in cars.
I owned all of them. They were durable, gave a long service life and could be used in other applications in addition to automotive. There are many older boats still floating that use the small block .M
My brother has a huge old wooden Chris-Craft that is powered by two 283s that still run like a top.
I’ve always loved the LS series for keeping that simple, pushrod design going. I was 18 and tore apart my valvetrain and put it back together with just a couple short 10 min UA-cam videos 😂
Not to mention the 4.3V6. It had same bore/stroke, pistons, cam bearings, main bearings, valvetrain etc as the 350. They put them in the full size “WorkTruck” and a bazillion Astro/Safari mini vans and S10/15’s. I’d still have my 96 Safari if it hadn’t have rusted into nothingness lol. 🚙

Old guy I used to work with used to talk about his 427 small block. Said it would tach up way faster than the big blocks and he was always the fastest car in the area. In a Nova I believe
To get 427 in a small block would take some fancy machine work. I don't know if it would fit. Cylinder wall thickness and crank to cam clearance would be a problem. I'm not saying it can't be done. I'm questioning if it could.
@@donmunro144 427/434 strokers are well established from the 400sbc. You are way behind the knowledge.
@@cuzz63 i never liked the 400. So I don't even consider it. I know that some love it.
There still so many of them running!! No flat cam issues no lifter issues no bs they just run!
Thank you for pointing this out. We need history to learn what works.
I will admit, those early 350s are a pleasure to work with. Much better than the tempermental LT1 I have now.
The funny thing is that, there are Japanese DOHC engines that are easier to work on than some of the modern GM pushrod engines
@@davidperry4013 Name one. I may be in the market soon.
I feel the 383 stroker is the best option
It really is - I remember reading about the first of the car rag 383 stroker builds, called _Dragonslsyer_ in, iirc, Carcraft circa 1992, and the end result was 450hp, then. A mind boggling output for a NA small block running on pump gas. Today? A streetable 383 using current head designs and modern EFI and ignition is easily capable of 550hp on pump gas - when I went HS 3 decades ago, that was big block numbers.
@@machinist7230 Built and tuned mild for the street, they make such a wonderful and useful motor. Their balance of power reminds me of the 327, which didn't get a mention on this video. But I felt was such an outstanding engine for how it could be mild or wild also.
Use six inch rods if you are going to be racing it.
took apart and resassembled a 350 when I was 16.. I was nervous I wouldn't do it right but the whole time I was thinking it all made so much sense. good motors
You missed the 327 I pushed it to 425 hp

Vortec*
327 ,302 zapper ..
I owned several small blocks some with all kinds of different cubic inch configurations.... miss those days....
Man .. One of these days I want to rebuild one of these small blocks for a project car. I hope that day comes when I have the room and extra cash because it always looked fun. My father was big into muscle cars before I was born and had a 390bbf falcon in my early years. It was amazing. After parents divorced it was like that part of him died but deep down I've always wanted to learn for myself. I think a nice G body or Fox body would be perfect. Someday... Someday.. ❤
What about the 327 the 302s and 400 small block Chevys?
Just imagine where we would be without these first small blocks. All HAIL THE MOUSE
Been there and totally agree! Built a 301 in 1967, my 61’ Impala was too fast…..engine new less than 300 miles, never had an oil change, someone liked it. It was stolen and stripped…….got the body back, never found out where it went!
My Firebird with a 305 has outlived two 350s I’ve had in 1500s,, that motor is bulletproof
The small block Chevy NEVER dies.
The SBC died in 1991. After that GM Powertrain took over.
@@Olds_Pwr I'm talking about there are still in use nowadays in old Chevys, hot rods, etc.
I've put 10k miles on a 350 with a rod knock that has 3qts of Lucas and 2qts of 30 weight and still pulls like nothings wrong 😂😂 (it's a 78 l48 with north of 230k miles)
I've got a 350 from 75 and all I've done is throw headers, intake and new carburetor at it and she starts up every time without fail I wish I could have been alive when they were new
Ever work on Chevys? It seems like everything fits everything else. For years and years.
They are great engine’s Chevy small block and big block’s I love them all ❤❤❤❤❤ they never get old
I've owned them all over the last 58 years. Also had a 262" as well in a 79 Monza
Did it have a busted off spark plug next to the firewall on the driver's side?
@@Simon-nautic Not that I recall. I do remembering unbolting the motor mounts and lifting that side up to change the plugs. Real tight fit.
283 for me!
Parts interchangeability is the friggin key here for me!! A buddy told me that if you ever had to, you could pull a piston off a 350 and drop it in a Harley.... Just beautiful eh
I've owned a 265, 283, 305, 327, several 350s, 396, 402. My favorite engine is 28 years old and only changed the water pump in 240,000 miles. My straight six, 4.0L in my Jeep.
That was a Rambler engine … 😂
I daily drive a numbers matching 1976 Monte Carlo with a 400 cubic inch small block.. 2000 miles a month in all weather.. it’s the most reliable car I’ve ever owned.
YOU LOOK OVER THE 327 SBC🔥🔥🔥🤔👌🏾‼️
The parts interchanging is one of the best parts about the small block, and even the LTI (second gen small block). I build motors and so often we put on 1990s heads onto 1960s motors, and we use rods and cranks and distributors fuel pumps etc etc. Unlike ford where the 302/289 and 351 and 351c are all different beasts, with silly things like different balanced cranks, you can swap parts from 1st and 2nd gen small blocks pretty much willy nilly with a few exceptions. They also put them into everything until 2006 or so (in the vans) so these engines basically grow on trees.
Love them.
Ford were always a pain in the arse … And interchangeability is why Chevys are so popular - cheap, dependable power …
I'm more proud of the straight-six engines from the big three car makers. While very underappreciated, those engines are what powered 95% of cars and pickups for decades. Grab any old truck that was used for real work like farming, and it's most likely going to have a six under the hood.
Yep. The 300 six from Chevrolet is big for a six cylinder and can put out some impressive numbers too! 😁
good for work but suck on the highway
They are great engines but 6 cylinder engines are expensive to build for HP and cost much more than a conventional V-8 engine will for making good HP and torque. Look up Clifford 6=8 who has been building HP 6 cylinder parts for many years and see how expensive it is to build one . I found this out because although I have built quite a few V-8 street and race engines I wanted to build a hot 6 cylinder Ford 300 6 and found out how expensive it is with not nearly as much HP or torque as a V-8 engine so decided to forget doing one .
Dont forget the 307 another great one its like a smaller 327
305 Dominated junkyards 😅
only because of people's ignorance. it was a secret power house. 350 never made 1hp per cube stock
With the stock 305 format they were old dog motors. The power to dollar went to the 350’s. If built correctly the 305’s could be made as high rev monsters, but again the 350’s still have the most respect and resources.
@@Backyardmech1
The 302 engine Chevy made for the 5.0 liter Trans Am series of racing in the late 60's was the engine that would rev out real high with it's short stroke, it was essentially a 327 with a shorter stroke crank from one of the 50's smaller displacement V8's mentioned in this video which reduced displacement to 302.
You couldn't rev 305's any higher than a 350, they both used the same crank and therefore had the same stroke, they're even interchangeable and bear the same part number cast on them, the 305 was nothing more than a low cost solution for a more fuel efficient small block by reducing displacement, it was intended to be a low reving engine that made sufficient torque in the RPM range where passenger cars need it, it was basically just a 350 with the bore reduced to attain 305 ci.
General Motors made HO versions of the 305 as a performance option engine for Camaro's and even in HO Trans Am's in the 80's but that was simply a case of them using what was available at the time, they were pepped up a little with better cams and different ECU chips in them to up HP 10% or so but the fact is the 305 really wasn't very good performance motor, the bore vs stroke ratio isn't very good for a performance engine and aside from factory limited classes that called for stock displacement engine's no one ever bothered building them for performance.
@@DRNEGOLICIS 1st gen LT1 is typing...
305 was good at what it made to do. The problem lies in the people behind the wheel. I still have an all original drivetrain in my 91' RS Camaro 5-speed with 156K miles, and it runs as good as it did 30 years ago. Just have to do regular oil changes and filters. On a side note, don't underestimate the power of Marvel Mystery Oil.
I wish all the old lifters ive pulled out came out as easy as theirs did
1973 small block 400 is my favorite!!! 4.125 bore!!!
350 is one of the best motors in my opinion
I got 510 HP from a carburetor chev small block.
My buddy is a engine builder/ machinist and put together a simple 406ci that made 634hp on carb for a pulling tractor...sbc is the best size to power v8 ever produced
@@jarvislarson6864Especially if you’re on a budget. When I was messing around with hot rods & customs in the ‘90s & early ‘00s performance parts for small blocks were sometimes cheaper than the stock stuff. There was just so much of it out there! It was cheaper to build a warmed-over performance engine than it was to rebuild a stock 350 with NOS parts. That’s assuming you were shopping mostly from Jegs & Summit & not doing anything too crazy, of course. 🙂
@@grahamstrouse1165 I couldn't agree more...for example few years ago I picked up a set of AFR 190's for $500 with nothing wrong with them and they're on a scat & wiseco internals 383 that would cost 10k + for the same power in a LS
everyone forgets a 305HO was around 300HP. a 350 never made 1hp per cube in any stock vehicle. 283 and 327 & 305 out performed it

Everything is better than a 305
My grandfather told me a long time ago about how tough the 283ci motor was. Apparently it was too bulletproof and it was discontinued.
We made almost 800hp naturally aspirated on a 360 cubic inch small block, chevy performance block, it was basically a beefy de-stroked and bored out 400 engine.
The little 283 is a screamer
I agree , with the exception of the 305 Chevy . It was an under-powered gas guzzler.
I have never been a big fan of gm but I know multiple old men with sbc 350 pickups with 400-500k original miles on them.
The darling of aftermarket performance production well into the early 2000's. And all because they were smart enough to make a rear sump oil pan that didn't have a steering center link running through the oil pan.
Still is way better than an LS out there
Not gonna include the amazing 327?? I had an 06 Silverado Z71 crew cab with only 25k miles and that truck was amazing. I put a 4” suspension lift with 32” MTs on 18” rims , Super 44 Flowmaster exhaust, k&n cold air intake , and an Edge Performance programming chip. That truck never had a single issue (probably bc I didn’t mud but I pulled people out). No repairs just maintenance all the way to 180k miles when I sold her.
Sorry for the rant 😂 I miss her.
Small blocks were so incredibly versatile, it is the go to engine for a quick running build that'll keep food on the table. Keep a spare Chevy around, because you'll never know when that junk Kia you got on credit is gonna break down. That small block will always start.
fun fact chevy brought back the 265 v8 for 94/96 chevy caprices. its the L99 4.3 v8 based on the lt1. the amount of times ive had to pop my hood to explain my 4.3 caprice is not a v6 is hilarious 😂 people just don’t know
I've had a lot of small Chevys, 307, 305, 350. I learned something. Replace with a Dodge 340.

Never heard of 305 associated with peformance.
As far as the block goes it's the same as the 350, just smaller bore, that's it, it can be done.
Yeah this is true... But I've seen some pretty nasty 305s though but that being said people don't build 305s nearly as much but when you say Ford 302 which is a similar displacement engine... you think of performance with those engines and it's a smaller engine... What is it a 347 stroker you can build out of those and several other displacements...
@@motersickel strokers are fine for regular driving but larger cylinders with a smaller stroke are preferred for peformance driving

You will never go wrong, with a small block Chevy !!!!!!!
I would argue that the SBC engine family set the standard for most internal camshaft engine's since the mid 50's
Nothing better than a 327 Chevy motor, maybe you forgot…
The 283 and 327 I believe began the better improvements on small block V8s, And this brought us here.
Small blocks are the second best motor made, vws ol flat 4 takes the cake imo, both strong easy to modify and have 40+ years of interchangeable parts, new motors make power but wont ever compare to the old school simple motors that a somewhat handy person can maintain without having to go to a dealership. Plus you can make respectable power for a decent price
The 400ci small block that came out in the 70s was the best
350, 3fiddy, easy to work on, easy to soup up.👍🇺🇸
I used to be a big block fan...until I turned my 360 into a 413 stroker. SBC/Dodge LA series/Ford 335 series are all capable of over 400ci and 500hp and ft lbs when built right. The only stock BB that put up more factory torque was the Buick 455...at 510. Lighter engine capable of the same power and more rpm? Yeahhh sign me up.
Crazy power for 70s

@@Formerlywarmer Examples as the 350, 396 and the 402 all rounded up but the 400 did not. Could have been because it was around the time frame GM had the rule nothing over 400 cubic inches in an intermediate sized car.
