People were thanking the manufacturers for holding the SAE data as being the bar. SAE horsepower is always going to be lower than a quick run to peak and shut it down test. It gives more accurate "in action" ratings. Keeps the rates down too.
Agree. I lean towards the 340 Six Pack. It was a monster. Very hard to find unless you built one. Saw a clip where it produced more HP than the advertised HP of a 440 on the dyno. I wouldn’t say no to a Ford 429 SCJ..
@@kentkrueger6035 ironically, the HP ratings were WAY over inflated to what they actually make when measured properly. Even with proper 2.5" exhaust, a 1970 454SS (450hp) Chevelle only made 364whp on a crazily optimistic setting on our chasis dyno with a combo that was as close to factory as you can get. Track trap speed doesn't lie. You can't BS a 108mph/3900lb car power rating too much.

Father-In-Law passed and left the wife and me with 7 classic cars. The Fords, all from the 1960's, had the FE engines and the MOPAR were 440 engines. I rebuilt the T-Bird's FE 428 engine in my shop and had the block bored and cleaned up at a machine shop. New heads. I'm 67 and have rebuilt 12 bigblock engines since I was younger. I don't do it for a living but I sure have a lot of fun in my shop. Currently, I own a couple of 454 vehicles (Chevelle and SS454). Someone mentioned the 327 engine. Those were great small blocks and the 340, 302, 351 Windsor. I rebuilt those as well back in the 1970's and 1980's. It's fun but expensive. I think the EV intiative will run parts prices way up. Please stick with American sourced parts. The Chinese cams are soft and I learned the hard way on that issue. Roller hydraulic lifters and cams are the way to go. Forged parts are the way to go.
small block had a deck height of 9.2- 9.5" bore spacing 4.3"-4.5", low deck big blocks 9.8"-10.00" bore spacing 4.6"-4.8", raise deck big blocks 10.375-11.00" bore spacing 4.8"-5.25".

I only saw 3 comments that mention Cadillac. The 71 500 big block was a 440 HP and 550 ft lbs with peak torque @ 2500 RPM. Only reason no one remembers it is the cars they put them in were 8,000 pound's and they were a luxury car so the exhaust was quiet. And crate engines shouldn't count.
There is/was a company in Lakeland, FL (haven't checked in a while) called CMS Cadillac MotoSports that had performace parts for the 572/500 engines. They did a lot of stuff for air boats. Always thought it would make a great pickup engine, Not much heavier than a smallblock 350 and a high nickel block!
Caddy 500 in 1970 had 400 hp.....in 1971 had 365....in subsequent years hp went from 235 to 220 to 190. Base curb weight of a 1971 Eldorado was 4800 pounds.

I had a 392 Hemi, but it was in a 59 Chrysler 4 door sedan. I traded it for a Buick Lesabre Convertible. With just a little work, the Chrysler would have been much better.

Whoever made this video has no clue what a big block is.,or why they were called big blocks. It was not based on cid but on the actual size difference of the blocks. Some car brands didn't have a small block or big block , like Pontiac

Interesting that it mentions the 429 Cobra Jet in the 1970 Falcon, then shows a brochure photo of a 1970 AUSTRALIAN Falcon. The biggest engine these had were a 351, either Windsor or Cleveland
Ford did in 1970 produce a 429 Cobra Jet Falcon, they took the cheapest no frills Fairlane and dropped the 429 CJ then rebadged it as a 1970 Falcon, it was produced in limited numbers and I almost had one but chose a Boss 302 instead, if you goggle it I am sure there are photos.
@@georgemartin7219 That's true. Ford did infact build a 429 Cobra Jet Falcon, that looked like the '70 Torino/Fairlane. They were a very limited production vehicle, rumored to be 200, to 300 hundred units. They were radio delete, rubber mat on the floor, and most were Toploader 4 speed cars.

A “pure” aluminum engine block would be like making a block out of bubble gum. In order to handle the stresses the aluminum will be alloyed with at least 8-10% silicon and about 3% copper to harden the surface.
The 426 Hemi was actually rated at 425 HP because that the Max hp that could be posted in the brochure. All manufacturers were limited to 425 hp at that time, even if the engine could produce more.
Golden era of Nascar 1963- 1973/74 when Ford and Chrysler battled it out GM(Chevy) was a after thought. Pontiac Super Duty was the hot setup in the early 60's. HEMI,427 FE HIGH RISERs were the hot setup. GM 427 ran ok(sometimes)but blew up alot after 300 miles from weak bottom ends trying to F around with the deep skirt blocks from Ford and Chrysler. This kid was lucky enough to see the Ford Torino Talladegas,Plymouth Super Birds and Dodge Daytonas at the Talladega race in 1970. I'll never forget the roar of those Aero cars.
Speaking of not knowing what you’re talking about. What about the 1970 Torino with the 429 cobra jet ram air or the 1970 Mercury Cyclone with the 429 Super cobra jet engine. Just saying,look it up.👍😁👍
The OP must not have heard of NHRA Top Fuel dragsters which have 500ci HEMI V8 engines making 10,000+ horsepower. However, if one is talking stock-from-factory road going vehicles of the 1960s/70s, I think that is the 1966 Shelby Cobra Super Snake CSX3015. I've seen it quoted 800 to 850 bhp.
The Caddliac Escalade is a Small Block LT4 6.2 and the Chrysler is also a Small Block 6.2 Hemi , the last real Big Block was the 8.1 Chev Big Block ! A really underated engine !
@@phordguy the bus engines came in 535 , and bigger and were truck engines with a 60 deg V. The 8.1/496 ci I mentioned as the biggest current big blocks, as it was based on the 366/396 original engine .
The 500 CID Cadillac had 400 hp rated from the factory, and like a lot of the factory ratings, it was actually higher. With very little work, it would easily make 500 hp.
Big block vs small block has less to do with cubic inches than people think. It has to do with bore spacing not bore size. Bore spacing is the difference between bore center of one piston to the next. Bore size is the actual bore size of the piston. Standard small block Chevy bore space is 4.400in and Chevy big blocks run 4.840in. Small block ford bore space is 4.380 and 4.900 for big block ford. Chrysler small blocks are 4.460 bore and 4.800 for Chrysler big blocks.
the Mopar LA and Magnum V8s had the 4.5" bore spacing. the B, RB, and Hemi V8 had the 4.8" bore spacing. in the Mopar/Direct Connection catalog the was also a 5.0" bore spacing in the RB/Hemi blocks. the gen 3 Hemi blocks are a 4.4" bore spacing.
@@MichaelBrown-yp1eq I’m referencing factory blocks. I know you can find blocks with larger bore space. I know Motown has a 4.500 for sbcs and I know someone about 10 years ago created a 4.600 “sbc”

@@sirswerve2493 I think everyone is talking about street legal factory cars 🚗 yes the 426 Hemi responded to modifications probably the best, but Dodges own 440 6 pack was faster out of the box,lived in those times and saw it first hand.
I love big brutal engines with butt kick torque. I also witnessed them get thumped by little engines back in the day. In the hands of the right boy, we had a small journal 327 '65 4-speed chevy-2 post with a massive solid lifter cam and 5.38:1's that put away all big engines around. A few years later another bad boy popped up out of nowhere with a 340 4-speed Duster. Again with massive solid lifter cam and 4.88:1's He beat the 327 by inches! Then came a 351 Cleveland that also was a stick and he could hang with them, but I didn't know much about it. My point is these were little engines that none of the big stuff had a prayer against. But it has to be the right boy.
I’m trying to focus but is that a 426 max wedge? I was about 15 when my buddies big brother asked me if I wanted to go for a ride in his new Belvedere. It was a max wedge. 4sp. Then off to Vietnam I went and made it home in 68 and in 69 my honorable discharge landed me a job in Chrysler central engineering at the performance department. As I listen to this Ai program, it mentioned my first project in the engine lab, was the prep for the 1970 440 6 bbl. I loved my dyno work but I also was discovered as a driver. On and on .
The 426 Hemi engine's "official" rating was 425 horsepower at 5,000 rpm, but it could produce more power at higher engine speeds. For example, one dyno test found that a stock 426 Hemi produced 495 horsepower at 6,000 rpm.
Yes the 332 FE ford engine was a big block, and the 400 Ford 335 series was a Small Block , both the 400 ci Oldsmobile 1960s engines were Big Block s but the 403 ci Oldsmobile was a small block, it had the distinction of being the biggest small block at 403 ci of all time untill the new Ford Godzilla Small Block at 445 ci very lately .

What about the aluminum block Chevrolet 427 back in the 60s I was a Chevrolet mechanic then and on the dino it put out 600 hp to the rear tires. I work for a GE daily daily Chevrolet in Livermore California then
The Ford 427 SOHC was claimed to have 616 horsepower on a single 4 barrel carb or 657 hp with dual 4 barrels. Why no love for these beasts? If you can't get it right then don't bother doing these videos or do some serious research.

You just said a bunch of BS. Big Block does not necessarily mean big cubic inch. The 366 Chevy is a Big Block. So was the 348. Ford made a Big Block 370.
The Ford FE is a big block 352, 360, 390, 427, 428, the 429 and 460 are a big block too, but they are not a FE. You also forgot the Chevy 409 and 338 which both are the same block.
@@lawrencebeckley2295 Your right , I get so upset when these people blatantly leave things out and I type to fast. They also forgot Buick 455, Pontiac 455, Oldsmobile 455, Buick 425. All these engines where great. I've driven cars with these engines and I can say that everyone of them could hold their own.
As soon as you add in contemporary crate engines, you'll fall behind monthly, maybe daily. As far as HP numbers, you have to decide whether you're going by advertised, crank, or wheel HP; same with torque. For historical engines (well, street engines), what counts as a small-block or a big-block kinda goes by what the manufacturer offered at the time. Through the 60s, it was pretty clear. Ford had small-blocks based on their original 221 ci Fairlane engine, including the 260, 289, 302, and, arguably, the Windsor. The Y-block legacy series, culminating in the 406, was big-block more by default than design, while the 427, 428, 429, 460, and the Cleveland all qualified as big-blocks. Chrysler small-blocks based on the 273 included the (late) 318, 340, and 360, while the B wedges, including the 361, the 383, 413, 426, and 440, were all big-blocks; ANY Hemi was by any definition a big-block. For GM, the Olds and Buick small-blocks somewhat derived from the 215 aluminum V8, but differently; I suppose the Buicks wer closer to it, with the front distributor. They came in 300, 340, and 350 ci sizes; the older nailhead (including the 401) would generally be considered a big-block, I suppose, as would the 425, 430, and 455. The Olds 330, 350, and much later 403 were small-blocks. The 330 started life with aluminum heads; all Olds small-blocks differentiated from the big-blocks (400, 425, 455) by lower deck height. Pontiac V8s were ALL of common exterior dimension from the '55 287 all the way through the last 455; they are ALL either big-blocks or small-blocks, or neither, according to your preference - although the 421, 428, and 455 were in the day sometimes distinguished from the lesser displacements (317, 347, 370, and 389), more on account of age and market positioning than anything else. All Cadillac engines (390, 429, 472, 500) would generally be considered big-blocks or, really, just Cadillac engines; they had gobs of torque and power, surprisingly good economy, and could be hot-rodded to extreme power levels, sometimes as transplants into Olds and Buick police cars and ambulances. We all know the split in Chevy engines. The small-blocks were based on the original 265 and included displacements of 283, 327, 350, 400, and, later, 302, 305, and 262. The 400 had the siamesed cylinders with the "steam holes". Big-blocks were obviously big-blocks, including tbe older 348 and 409, the 427 "mystery engine", and the 396 family ("Rat" motor), including the 366 (truck), 396, 402 (sometimes called 400), 427, and 454. The much later LS engine probably counts as neither; it is NOT part of the "mouse-motor" family, although its engineering benefitted from over 50 years' experience with the earlier design. What is true about ALL these families of engines is that the power and torque RELIABLY produced depended on the conformance of the example to engineering specification (blueprinting), the application in which the power was to be extracted (e.g. a highway cruiser may never see 5,000 rpm), the mix and compatibility of engineering features, including speed equipment, employed to address the application, and appropriate tuning of the same.
Your engine history is very well done. However, you left out the Chevy 307 small block and the Chevy big block 402 was still called a 396. I had one in my '70 SS Chevelle.
I've heard this announcer all over UA-cam. I just wonder if this is actually a person speaking or an A I computer generated. There are a high number of English words, I guess if a broad caster was able to speak most of them and recorded that the program could assemble a conversation. Hmm.. maybe
This is an AI read, but it was trained on the sound of an actual documentary narrator from the '90's and '00's. He was the voice of a lot of Discovery channel shows on engineering and sciences.
They didn't lie. They just didn't tell the whole story. For example; the Boss 302 was rated at 290HP @ 5800 RPM. Ford simply didn't mention that at 6800 RPM, it was around 375.
The 429 Torino is alway so underrated. There must not ever be a decent driver available when it comes time to do a 0-60 or 1/4 mile test on one. I for one has witnessed a stock 429 Torino do 0-60 in 4.5 seconds.

I only saw 3 comments that mention Cadillac. The 71 500 big block was a 440 HP and 550 ft lbs with peak torque @ 2500 RPM. Only reason no one remembers it is the cars they put them in were 8,000 pound's and they were a luxury car so the exhaust was quiet. And crate engines shouldn't count.
There is/was a company in Lakeland, FL (haven't checked in a while) called CMS Cadillac MotoSports that had performace parts for the 572/500 engines. They did a lot of stuff for air boats.
Always thought it would make a great pickup engine, Not much heavier than a smallblock 350 and a high nickel block!
Caddy 500 in 1970 had 400 hp.....in 1971 had 365....in subsequent years hp went from 235 to 220 to 190. Base curb weight of a 1971 Eldorado was 4800 pounds.

The 500 Cu In Eldorado’s compression and power went down in ‘71, the ‘70 had higher compression and was rated at 400 hp and 550 lb ft of torque.
Remember seeing one of those 500 engines back around 1984 in a black two door 1970’s Cadillac coupe. The radiator was big as something you would see in a diesel truck.

Ford did in 1970 produce a 429 Cobra Jet Falcon, they took the cheapest no frills Fairlane and dropped the 429 CJ then rebadged it as a 1970 Falcon, it was produced in limited numbers and I almost had one but chose a Boss 302 instead, if you goggle it I am sure there are photos.

You should have posted "big displacement blocks" since this seems to be the actual theme.
A “pure” aluminum engine block would be like making a block out of bubble gum. In order to handle the stresses the aluminum will be alloyed with at least 8-10% silicon and about 3% copper to harden the surface.

Big block vs small block has less to do with cubic inches than people think. It has to do with bore spacing not bore size. Bore spacing is the difference between bore center of one piston to the next. Bore size is the actual bore size of the piston. Standard small block Chevy bore space is 4.400in and Chevy big blocks run 4.840in. Small block ford bore space is 4.380 and 4.900 for big block ford. Chrysler small blocks are 4.460 bore and 4.800 for Chrysler big blocks.
the Mopar LA and Magnum V8s had the 4.5" bore spacing. the B, RB, and Hemi V8 had the 4.8" bore spacing. in the Mopar/Direct Connection catalog the was also a 5.0" bore spacing in the RB/Hemi blocks. the gen 3 Hemi blocks are a 4.4" bore spacing.

New Cadillac and Challenger do not have big block engines
True.
Chrysler hasn't had a BB since 1978, and Cadillac dropped theirs when the 368 ceased production in 81 or 82.
As soon as you add in contemporary crate engines, you'll fall behind monthly, maybe daily. As far as HP numbers, you have to decide whether you're going by advertised, crank, or wheel HP; same with torque. For historical engines (well, street engines), what counts as a small-block or a big-block kinda goes by what the manufacturer offered at the time. Through the 60s, it was pretty clear.
Ford had small-blocks based on their original 221 ci Fairlane engine, including the 260, 289, 302, and, arguably, the Windsor. The Y-block legacy series, culminating in the 406, was big-block more by default than design, while the 427, 428, 429, 460, and the Cleveland all qualified as big-blocks.
Chrysler small-blocks based on the 273 included the (late) 318, 340, and 360, while the B wedges, including the 361, the 383, 413, 426, and 440, were all big-blocks; ANY Hemi was by any definition a big-block.
For GM, the Olds and Buick small-blocks somewhat derived from the 215 aluminum V8, but differently; I suppose the Buicks wer closer to it, with the front distributor. They came in 300, 340, and 350 ci sizes; the older nailhead (including the 401) would generally be considered a big-block, I suppose, as would the 425, 430, and 455. The Olds 330, 350, and much later 403 were small-blocks. The 330 started life with aluminum heads; all Olds small-blocks differentiated from the big-blocks (400, 425, 455) by lower deck height.
Pontiac V8s were ALL of common exterior dimension from the '55 287 all the way through the last 455; they are ALL either big-blocks or small-blocks, or neither, according to your preference - although the 421, 428, and 455 were in the day sometimes distinguished from the lesser displacements (317, 347, 370, and 389), more on account of age and market positioning than anything else.
All Cadillac engines (390, 429, 472, 500) would generally be considered big-blocks or, really, just Cadillac engines; they had gobs of torque and power, surprisingly good economy, and could be hot-rodded to extreme power levels, sometimes as transplants into Olds and Buick police cars and ambulances.
We all know the split in Chevy engines. The small-blocks were based on the original 265 and included displacements of 283, 327, 350, 400, and, later, 302, 305, and 262. The 400 had the siamesed cylinders with the "steam holes". Big-blocks were obviously big-blocks, including tbe older 348 and 409, the 427 "mystery engine", and the 396 family ("Rat" motor), including the 366 (truck), 396, 402 (sometimes called 400), 427, and 454. The much later LS engine probably counts as neither; it is NOT part of the "mouse-motor" family, although its engineering benefitted from over 50 years' experience with the earlier design.
What is true about ALL these families of engines is that the power and torque RELIABLY produced depended on the conformance of the example to engineering specification (blueprinting), the application in which the power was to be extracted (e.g. a highway cruiser may never see 5,000 rpm), the mix and compatibility of engineering features, including speed equipment, employed to address the application, and appropriate tuning of the same.
Your engine history is very well done. However, you left out the Chevy 307 small block and the Chevy big block 402 was still called a 396. I had one in my '70 SS Chevelle.
You forgot the 472 Cadillac. And the olds and buick and pontiac 455 super duty. They have lots of power.

I've heard this announcer all over UA-cam. I just wonder if this is actually a person speaking or an A I computer generated. There are a high number of English words, I guess if a broad caster was able to speak most of them and recorded that the program could assemble a conversation. Hmm.. maybe
AI for sure.
Definitely AI
This is an AI read, but it was trained on the sound of an actual documentary narrator from the '90's and '00's. He was the voice of a lot of Discovery channel shows on engineering and sciences.
That pic was of Sonny Leonard with his 1000 CI engine👀
I’d like to see the old big blocks put on dynos. Manufacturers lied about power outputs for insurance cost reasons.
They didn't lie. They just didn't tell the whole story. For example; the Boss 302 was rated at 290HP @ 5800 RPM.
Ford simply didn't mention that at 6800 RPM, it was around 375.

The 429 Torino is alway so underrated. There must not ever be a decent driver available when it comes time to do a 0-60 or 1/4 mile test on one. I for one has witnessed a stock 429 Torino do 0-60 in 4.5 seconds.
