@@shanemitchell477 I offered my 283 to swap with that engine in a '82 TA. Actually a 4" bore and 3" stroke. High lift, low overlap cam. 1.98 valves. But 9.5 to 1 compression. So not quite as HP out. But a bit more torque. Oh and meets '82 AQMD and CARB. But fails with the open the hood eyeball check. In Californey. Most of the external plumbing would be missing. Yep you can tune for HP and Eemotions. Well you could not buy pump gas in the 80s to run at 68 spec compression. 9.5 compression no problem. My next go faster was a Lincoln LSC. Was close. But not '67-69 302 Chevy close. Then along came the 256 cubic inch Alas 6 in 2006. That moves a T-Blazer smoothly and quietly with only 290HP and two less cylinders with no puffer.

Great video---it's rare that I see one that's this well-researched and accurate. I had both the Chevy 267 and the Olds 260. At the time, GM released press saying these engines had "the fuel economy of a 6 with the performance of an 8"----no, it was exactly the opposite, the worst of both worlds

[@sombra6153]

This AI lacks a depth of understanding. I’d liken the way the video was researched to Igor being tasked to find a brain for Frankenstein’s monster. The only V-8 in this video that was truly terrible was the Olds 5.7 diesel. The Chrysler Lean Burn wasn’t spectacular but it was the electronics, not the V-8. Some of the others may have had runs with bad substandard components but seems like the manufacturers fixed those types of issues. Lack of horsepower compared to previous years or the smog era doesn’t necessarily make for a terrible engine for grocery getter and commuter cars.

[@pancudowny]

An engine being configured with a two-barrel carb has nothing to do with being able to run on cheap fuel, as I've found over my years of driving 4-barrel engines. Running a ridiculously low compression ratio, without any form of forced induction, however.... BTW: Chrysler's reason for going with the hemispherical combustion chamber in the first place was to be able to extract the maximum power possible from low-octane fuel. How low of octane typically was available in the early-50's, I cant say. But I do recall seeing (without audio) a commercial for Speedway 79 gasoline... so there's that.

[@PeopleAlreadyDidThis]

Remember that Phillips 66 was a big deal in the days of 50 octane gasoline. Prior to the late-50s and 60s horsepower race, people liked smooth, quiet, economical engines. Low compression ratio delivers that.

[@MikeekiM-vh5se]

Plus with the Hemi it had 140 hp the Ford V8 had 106-110 hp and the Chevy had 115 so the Dodge was a rocket! Chrysler Hemi had more power because Chrysler was top of the line so bigger engine,more power..Desoto was second in line so bigger engine and more power than Dodge...Plymouth never had a Hemi in the 1950's as it was the companies entry level brand and the competitor to Ford and Chevy,so their 6 cyl was in line with those brands.

Add a new distributor and ecu(or go back to pre 1971 with points ignition) and the engines were the most reliable engines ever made in history of the automobile..With lean burn/spark control computer you should put a pre smog carburetor to gain up to 75 hp!

Given that the flathead V8 basically put the automobile on the map let alone the Ford product. Also given the fact that these Flathead engines are still being reproduced today for Hot rod applications particularly a small for roadster cars. If they were so terrible why are they still being desired today. They're actually one of the simplest and best motors ever built. And of course they're not going to meet today's standards of reliability and mileage those motors were built different back then it was a different time for the time those were the best ever built.. and technically today less moving parts less maintenance low cost. Did those motors have their problems yes they did all engines do especially when they are newly introduced. And of course just because it didn't make that much power also does not mean it's a terrible engine. The biggest one ever was barely over 5 liters. Smallest one was about 130 cubic inches. And the crazy thing is is right at the end of the run of the flathead V8 it had already improved vastly. The only reason why the Flathead cease to exist as a mainstream engine was because it was so outdated by the time innovations came along for the newer V8S coming out. The only conversion that could have made the Flathead a formidable contender with the newer style engines with overhead valves is the Arden overhead valve version on the flatheads. And sadly those heads are almost impossible to find to this day. Had those heads been mass produced the Flathead may have survived a lot longer than it did. Overall I'm just glad to see them still around and being used for their into the purposes in honor of the tradition of the original V8.

Chrysler Australia was first here with electronic ignition in 1973 and it was most of ten years before ford or holden went electronic.

Funny thing: When GM figured out how to make a splayed-journal crankshaft by the late-70's, it made the Buick 3.8L V-6--and any other V-6 GM developed from an existing V-8 design (Chevy 4.3L) obviously a better engine than a extremely-small displacement V-8... especially when the latter were running such ridiculously low compression ratios.

My parents bought new an Oldsmobile Cutlass sedan (Based on the G-body platform) that had the Oldsmobile equivalent of the Chevy 262: The 260. And it too only produced 110-hp. The worst part: My dad bought it partially because it's torque curve, as we'd be towing a single-axle camper trailer with it. Sadly, the V-6 model had a better one... but the dealer was trying to get this brand-new model, which was already a year old at the time, off the showroom floor.

Years ago when I was about 20 I was looking for a 1932 ford to restore. I told a retired farmer and he said why I had one of those and it was the biggest lemon I ever had. That thing was a LEMON!! After talking to him I found out it was about the very first one that was made and had lots of engine problems. Also when I would research the first 32s over the years was the first V8s were the hardest to find and today bring the highest price!

[@michaelmarburger1003]

I noticed that a few of these motors on this list were from the 70s to the early 80s when the auto industry was facing an oil shortage and higher priced gas as well as new restrictions coming from the EPA. It is important to know that during this time period, a lot of manufacturers did not do their due diligence in reference to research and development in order to try and rush new and more fuel efficient products to the market and this resulted in a slew of horrible motors coming from all of the big 3 automakers. Most of these products looked good on paper but failed on the road as you see that a lot of these motors did not stay in production for long.

[@namvet_13e]

Narrative derides all these engines for low power, but the pictures generally are of high performance engines with multiple carbs and other performance features. He also should have noted the way horse power rating changed to deduct the power lost on accessories and in the drive train. Net horse power at the wheels is substantially lower than the old method. However it is true that all car makers had to struggle to comply with unreasonable fuel efficiency standards.

[@pancudowny]

About the smaller Ford V-8s (255- & 302-ci.) of the 80's: I find it ironic that by the '85-y/o, they were able to produce a turbocharged 4-cyl. that made more horsepower than a V-8 of more than twice it's displacement at the time, only to de-tune the former the following year... for seemingly no explanation that even I can figure of than Ford just wanting it's V-8s to look good. Had they continued development of the SVO 2.3L (As it's known by) it probably could've produced 250-300hp by the early-90's, making the V-8's redundant except in applications seeing high-load demands (full-size trucks & vans, namely) and Police specialty models. But no... the carbureted Turbo 2.3L of '79, when placed in the Fairmont, gave & left with people a bad taste in their mouths. And the very malaise era of performance of the 70's left them longing for high-power V-8s as well. And since people [on average] are too stupid to comprehend complex things....🙄

[@shanemitchell477]

They do, but Mazda makes it now.....the 2.3 Mazda engine is based off the SVO 2.3. It makes 263 hp last I checked. The only problem is we now have many 24 valve V-6 in cars that make the same as the turbo 2.3 Mazda. It's in the Mazdaspeed 3.

[@carlcushmanhybels8159]

Ah, the '79 Ford Fairmont, worst Ford I've ever driven (as a Govt car, 1983, one of the worst cars ever made by Ford. With its horrible low torque or power, a mismatched 'buzz-bomb' auto transmission: engine slowly wound up to high revs in a low gear, --trying to get out of its own way, then "Clunk" shifted bog down to the next gear, no... Shocks were completely worn out from jouncing on clay roads on the rural Navajo Res... 'Supremely' dull styling. Bad rear drive traction in snow... Luckily, as a shared Librarian I often had the use of an old-style (large) Jeep Cherokee 4wheel drive the 18 mile dusty or muddy backway between schools.

[@xaenon]

Why? COSTS. Turbochargers are expensive. Displacement is cheap. That applies to manufacturing and to sales. Give a guy a choice between a naturally aspirated V8 that makes reliable, cheap, low-maintenance power, or a high-tech, expensive hair-dried four banger... yeah. Also, turbos are warranty headaches - a lot of people don't know how to drive them properly. A guy I worked with would park his car, rev the engine up, and then kill the ignition so that he could hear that turbine spin down..... NOT HEALTHY. When I cautioned him that the turbo spinning without oil pressure would kill it... he shrugged. "It's under warranty..." Akso remember that in athe mid 1980s gas prices fell sharply here in the US. After years of $1.50-something a gallon, prices fell to below $1 a gallon, Thirsty V8s were back in style... and Americans, as a general rule, don't f__king LEARN.

Some of the later 4.8s had poor head castings, a supplier issue. Porosity would allow coolant into the oil. By removing a valve cover the vendor casting mark would pretty much give away why your oil looked like tar. Sister's truck had a one like that. We just put in a crate engine vs try to fix it.

[@petepeterson5337]

Agreed. I had one in the bulbous 1992 Caprice. I was lacking in power but was fairly trouble free. I had an odd failure of an edge card contact on the engine control module (located inside the panel by the front passenger's feet) that was repaired with contact cleaner and needle-nose pliers. It was a tribute to the factory service manual that enabled me to debug down to that level. With its redundant injector throttle body fuel injection, I was not stranded by the failure.

[@richardmaurer9002]

I think that the ‘32 flathead was maligned a little. For one thing , the fuel pump position caused vapor lock? Apparently Ford didn’t think so, it remained in the same place until the end of production in ‘53. Water pumps were the same until ‘36. He never really addressed the real reason they ran hot, which was the exhaust passages in the water jackets.

Hi Just Cars! I am 64 year old retired ASE Automotive Service Technician, and I was also a state emissions inspector/technician. In the mid 1970s to the early 1980s, "The Big Three" automaker(s) performed a very poor job in regards to engine drivability and automobile performance. The big three automaker(s) could of performed a much better job, if they wanted to and hear is why. If you bought let's say a 1975 to 1981 Pontiac Firebird Trans-Am, with an SAE net rated horsepower, (1972 and after) or a gross rated horsepower (1971 and before) the rated horsepower was really not too bad, coming from a big 4 barrel carbureted emission controlled V8 engine. The main issue, was that the air/fuel mixture(s) where and still are set up to run very lean. Not all emission control(s) effect horsepower, and by the way, most emission control(s) actually cancel and/or stop working, in regards to wide open or near wide open throttle, this often include(s) the air pump, EGR valve, and last but not least, the catalytic converter(s)! But in the mean time, the car would be equipped with a very unprecedented 2:50 to 1 rear end gear (differential) axle ratio, which is not at all performance ratio. If you own a mid 1970s to early 1980s emission controlled performance automobile, I suggest that you, lower the rear axle ratio first before removing any emission controls, and you will be in for a real treat! I had an all stock 1977 Corvette with a factory 350 L-82 engine, factory Turbo 400 transmission and a factory 3:55 to 1 Positraction rear and it performed 14.8 @ 119 MPH in the 1/4 mile with no modifications and all emission control(s) present. You notice that I capitalized the word Positraction, that is because Positraction is a trademark of Chevrolet Motor Division of GM, meaning closed differential. Please tell me what you think! Dave...

[@MikeekiM-vh5se]

I know with Chrysler the net hp engines were different than the gross ratings in more ways than just going from net to gross.. Chrysler engines all had lower compression~reduced horsepower and torque. Chrysler engines had different camshafts,crankshafts,heads,carburetors and exhaust systems all killed power..They were a lot weaker than the older engines rated in gross.. Example I had a stock 1971 Charger RT 440 Magnum,727 auto and 3.23 gears also had a 1972 Charger rallye 440 4 barrel,727 auto and 3.23 gears the 71 would struggle like crazy for traction and when I had better tires etc it ran high 12's in the 1/4 mile stock..The 1972 also could smoke the 14 inch bias ply tires easily(even noted in original road tests) but could hook up better if you know how,it was over 1 second slower in the 1/4 mile all the time.That is over 100 net hp to make a car gain that much more performance in the 1/4 mile. Both cars were stock and this was 1976.My father bought them both new and kept them for decades,I own the 71 today.Uncle owned a Chrysler dealer from the 50's -90's.

I thought the car was better for more than that; it had 390 V8 with 300 HP. I told my dad, who B-T-W was a great mechanic, we changed the sparkplugs, did nothing else. I went back to the freeway, this time 115MPH!!! Ha! 7 plugs were easily accessible, the 8th could only be reached by removing some framework situated around the motor. That was a fine car! It was not perfect, but I think that was one of the best FoMoCo ever produced.

[@dozerm.4108]

The Chevy 305 was later a good engine, produced til 1995. The Olds 260, slow but reliable and almost impossible to overheat. The Cadillac 8-6-4, the system itself was bad, unplug it and you had the same reliable 368 from 1980. The Cadillac HT (hook and tow) 4100 should be on your list instead.

[@JimThomas-o4x]

I will admit, the GM diesels of '80-'85 are worthy candidates for worst engine honors. Running a close second would be the Cadillac 4.1 liter V8 from '82-'87. These engines were severely underpowered and unreliable. The aluminum/cast iron mating surface between the intake manifold and the block created an expansion rate imbalance that inevitably caused gasket failure. The coolant found its way to the oil, washing out main bearings, and causing catastrophic wear of the cam lobes. These things were a nightmare. (By the way- the engine pictures in this video do not always match the engine being discussed.)

[@dannysdailys]

I had an Olds 260 in a 76 Cutlass Supreme. It was an excellent engine and shouldn't have been on your list. I once had a 442 400 and was familiar with it. But it only got about 70k on it before the body rusted out. The engine was very smooth. And while no hp junkie, it was a standard 350 Olds engine and parts were readily available for it. The Buick 6 was total garbage. And my Cutlass rusted out way before the driveline failed. This car was so bad even the back bumper fell off from rust. And all the GM's of the time did the same thing. A horrible time for GM cars no doubt. But it was a gorgeous car and I loved my Cutlass Supreme all the way to it's accelerated decrepitude end. Today, I won't own a GM. And that's not why. That was a 2006 Impala SS, their most expensive car, that went the other way. It's body didn't rust; BUT EVERYTHING ELSE DID. It was such a junk car, I had to replace the transmission cooling lines twice, and the power steering hoses twice. Everything corroded and failed and when even the trunk seal started leaking, 275 dollars again. That was it, I swore off GM completely and it was GONE. The prettiest piece of garbage on the road. Thank the auto gods Mercedes bought out Chrysler. That gave me some time with Mopar at least and I bought four of them and still have them today. 3 Jeeps and an AWD supercharged Dodge Charger. One will be 20 years old next year and it still running strong and looks great. Then Stelantis came along and Mopar is off the list as well as GM. Does Mopar even exist anymore? I'm not even sure. SRT doesn't, and all the Mercedes are gone. Luckily all of mine are pretty new and I'm the one who's retired. LOL

Where is the Ford (Ferd! 😆) Y-Block with a plague of oiling issues for the top end (rocker arms/shafts) due to a very bad design of the oil galleries, that was also used in one of their inline 6’s with equal identical issues? And to compound the oiling issues, the Y block V8’s had that stupid cross over exhaust pipe across the front of the engine that dumped heat over the engine that caused them to run hot (and the flat head V8 sometimes used the same stupid set up!) and also dumped so much hot gases through the passenger side exhaust manifold that it pretty much glowed red, compounding the poor oiling issue by coking the oil in the exhaust valves on the passenger side causing sticking of them sometimes and overheating them, causing warping and burning? Also, the Y block had, for some unlocked reasoning, an odd, different firing order that made these Y blocks sound like they had a misfire when they did not, especially when fitted with single exhaust with that dumb cross over “knuckle burner” pipe! And the true cause of overheating in the Ford flat heads was NOT the 2 water pumps, but rather, the exhaust passages in the block being too long to the ports where the 3 branch exhaust manifolds attach to the block, and run through the water jackets where the high heat dumped into the coolant and overwhelmed the cooling system, often generating steam bubbles that caused pockets that blocked coolant flow to the radiator. Henry Ford wasn’t that bright. He saw this design as good in winter for fast warm-up and cabin heat, not ever considering severe overheating in the SUMMER!! Duurr! 🤪 This issue is why other flat head V8’s like Cadillac had a “hot V” design with intake and exhaust manifolds in the valley up top to keep exhaust heat out of the cooling system, even insulating the manifolds and down pipes in asbestos to prevent radiant heat from being van issue! Engineers Ford never had and still don’t Every engine they ever made literally belongs on this list! All were a fail in one way or another! 🙄😬 Cheers! 👍🏻😊

Those lean burn Chrysler engines were HATED by Chrysler fans. All of the manufactures mid 70s to early 80 engines tended to be awful. Chrysler had an addition problem. The company was in a bad situation. This led to the hated "K" cars. Overall the engines that were choked down to meet MPG requirements or just designed as fuel efficient engines seem to be all over this list. This should be noted by GM, Stellantis (idiots IMO) and Ford. Ford, IMO, has done better than anyone in managing their car models to have some performance they can sell and cars whose fuel efficiency is high enough to offset the former models performance. GM had announced, a couple years ago I believe, that they were going to stop all car models. That implementation appears to have drug on much longer than GM wanted. Stellantis promoted Dodge as their performance brand. Now with all the carbon credits they have had to pay to keep it that way, Stellantis is almost universally going to hybrid or some form of high MPG engines. This entire fiasco that many US companies are fighting is INSANE MPG requirements. Why do these exist? Simple - force the fake global warming on humanity. It has been global cooling then global warming then global cooling than global warming and they got tired of selling 180 degree opposite problems all the time. Now it is global "change." Of course it changes - it is called WEATHER. Our temperature and carbon in the air have been perfectly normal. The more carbon is taken away the less green life exists. The less green life that exists the less oxygen exists. The less oxygen is bad for humanity. This is the definition of fascism/Corporatocracy. Ultimately they want to create a feudal society where you are in effect all slaves to serve the "lord" - the elite international corporations. DON'T BELIEVE ME. Read the #1 goal on the GA Guidestones they destroyed. To keep population at less than 500 million for the Earth. That means 7.5 BILLION people have to be eliminated. 2 Read about the UN Agenda 21. 3 Read the UN Agenda 2030. 4 Read about World Economic Fund. There are many more. Educate yourself or practice yes sir lord and giving everything you have, including your life, to your lord of the manor. Do you want to own nothing?
