- I gotta say, it's rather unfortunate that there are so many American engines on this list, but you cannot deny the fact that many of the engines we listed are just weak. Yes, they're bottled up with government-enforced restrictions, but you could argue that's a side effect of less-than-ideal engineering, but that's a topic for a different time.

I wouldn’t say that cam in block limits hp … it was 90% emissions limiting this engines even a old 6.2 can easily be turned up to 180 hp without a turbo
First Viper was way undertuned for reasons of longevity of the drivetrain. I was a chassis designer on the first gen, preproduction engines made a LOT more but tore up drivetrain parts.
Wow interesting, what was it like to work on such a neat vehicle?
charlie dee Wish they still made them, but I want to get a 99 gts. The viper v10 is just a monstrous powerhouse even as they were. Do you know if there is any merit to the rumours of the forged crank and pistons in the late 90s models?
@@bennyboyy7 the 1999 Viper was the last year of the all forged motor and the 906 cam shaft. And just to let the public know, I had a dyno at my shop and every Viper we dynoed made way more power than what they were rated.
Also the 1999 Viper was all a concept car that was suprisingly goes to in production. Chrysler wasn't sure how the car would sell, so they didn't tune up the engine. After that, the second gen was better.
@@SimplyTakuma You're ten years late. The concept car was shown at the Detroit International Auto Show in January of 1989, the production car came in 1992. I know this from being there, I was in the room when Iacocca announced it was approved for production in May 1991.
'02 GMC 8.1l only put out 345hp and 455ftlb. But my understanding was gm and Ford were not looking for high performance but rather longevity. Hence why these 8.1l, 6.0l, 5.4l and 6.8l engines are still around with well over 200 to even 300,000 miles plus on them. You look at current truck engine options and have to decide which failure you want to roll the dice on.
That’s interesting, good point. My 5.4 now has 325,000 KM, still going strong and sucking gas like a smoker sucks cancer 😂
the 8.1 big block gasser from GM has a very low rpm limit so it acts more or less like a diesel out puting power downlow instead of up high
@@csgsavagebanana8102 exactly. My 6.8l is the same way. Builds torque fast. Towing feels more like a casual drive. Modern engines you gotta wind up.
Agreed, an under-stressed engine will just keep on going. High output/ liter engines just means it will break itself faster.
My dodge 4.7 still runs strong and it’s kind of the same concept only in 1500 trucks.
Its almost impressive how they managed to extract so little power out of them
😂😂😂😂
MUH EMISSIONS
Hey now the iron duke did have this unique feature you can't get on other engines called catching on fire 🤣
Dude. 400 hp in the early 90s was impressive
It was the first time there had been 400hp available from the factory in a while. Unless you had a racecar
Yes it was back then But he’s a young buck , probably was still in school when the viper came out .
It's about the HP per liter. 400hp out of a naturally aspirated 4 liter engine is awesome even today, 400hp out of an 8 liter naturally aspirated engine isn't.
@@badass6300 ur missing the point… In early 90s 400 hp was top tier… 5.0 mustangs were 225 hp…
They didn’t have the technology we have today….
I agree. 400 hp out of a 8 liter v10 today is a dud.
@@hunterbidenscrackdealer3753 The problem is that in the early 90s the japanese were making slightly 100hp per liter naturally aspirated, which is double the HP per liter compared to the Viper. But the Japanese refused to make big engines, if they did, they would have dominated the world during that time period.
I have a 1973 Mercedes 220d diesel, 2.2L makes 60hp in a 3,000lb car. It is borderline dangerously slow but I love it. Mercedes gives a reference chart with the owners manual to estimate how much time it will take to accelerate around a car in a passing lane and it’s pretty funny to know that a 28 sec 0-60 was acceptable even back then.
Bro for the love of your own safety pls put a turbo on it
@@Fat_moose_420 fr turbo diesels built different
“Borderline” can you not spell unacceptably or what
There were lots of slow cars even in the heyday of the 60s muscle car era. Chevy sold lots more Chevelles with the 250 I6 and 307V8 than they did with the halo motors like the 396 and 454 SS. I'm sure the 250 was not rated much more than 150HP or so, gross HP, not net.
A 1.0L Geo is about to run away from you.
Correct on the 6.2 Detroit. It is gutless. I own a 1984 C30. Still to this day. It just will not die. It has not lived an easy life either. It has gone to work since 1984. It also does it at 30 MPG. Love that truck
I loved the 6.2, but they were gutless. That was known when you bought it.
Diesels have very diffetent logic. Displacement is not very connected with power and fuel consum.
i have 5 of them. love them. they are in trucks that i consider and use more like street legal "tractors" not great power to weight, but they just keep putting along as i need
in fact with 5:68 lockers, big tires and full of tools weight, i have one that one easily out pulled my friends 800+ super $70k whatever it was though mine was maxed at about 50mph, his was fast and felt great on the freeway with great fuel economy
The cad 500 has potential. 11.1 with early 472 heads or 13.1 with 425 heads. Add the aluminum intake and a distributor curve and they are beasts. Forged steel crank, these things in stock form are bomb proof. I ran a 1974 472 5 quarts low and overheated it. Added oil and water and she fired right back up and continued on my trip. Only 80ish pounds heavier than a 350. Unlike a hot 350, this monster will idle smoothly and all that torque is right off idle. These can be the unsung power combo
Ever hear of Project Bad Seed by Hot Rod Magazine back in uhhh late 90's? Take a Caddy 500, warm it up, add it to a Chevette mounted half into the cabin, go drag racing. Look it up!
@@evi1dav3 that's when I started following Steve Magnante
The English Electric 12CSVT locomotive engine is a V12 diesel, 185 litre displacement (pistons are 10 inches in diameter), and it produces 1750 horsepower, less than 10 horsepower per litre. But it sounds amazing under acceleration.
And all to spin a generator. But with a prime mover in a freight engine it's all about hours between rebuilds.
Will this fit in a Miata?
@@lincolncontinental8249 might need some cutting around the engine bay, but yeah, an engine bigger than the car should fit.
@@lincolncontinental8249 Considering a majority of them are in locomotives, definitely not.
@@lincolncontinental8249 under maybe
I mean, my 95 f150 has a 5.8 with like 180-220 horsepower, and torque is anyones guess. I can't seem to find the actual numbers, but it is pretty pathetic.
Yea people talk $hit about 4.6 but anything but the 460 and 7.3 was weak without a major overhaul
@Back Road Boy 460 is an insanely capable engine. Just not from the factory.
The 7.3 IDI was pretty weak, but the 7.3 Powerstroke is plenty for its intended application.
The 4.6 is at least according to some one of those million mile engines like the 7.3, just not tons of power or even really capability of making power.
325 torque is what it should make
@Cody Parker cool, any idea on a solid horsepower number?
@@duckdestroyer2412 210 325
To be fair my old iron duke s10 was the only rig I've ever had run out of oil,catch fire, burn for 30 mins before we got it out. Then start and drive the 20 mins back to the house before it caught fire again. Truck still ran when I sent it to the wrecker
Intresting history side note, the Mustang II wasn't available with a V8 in North America, in 1974 unless you bought it in Mexico. Speaking about the Caddy 500, in 1970 the 400 hp was gross after 72 the hp was measured net (as installed with all accessories) so that did significantly drop the numbers, not to say that it wasn't a smog-dog. The 70's brought emissions and things like CAFE cut the nards off everything. The technology wasn't there to meet the standards so you ended up with low compression, poor flowing heads, anemic cams, convoluted vacuum hoses, smog pumps, and restrictive exhausts... good times.
Rolls-Royce Corniche - pronounced "CORE-NEESH." It is a French word for "road cut into the side of a cliff." Tje Corniche was the somewhat more sporting Rolls-Royce, available in 2dr Coupe and Convertible. The 6.75 V8 was also in the Silver Shadow Sedan and Phantom Limousine.

I would love to see a video on your opinion of the most reliable engines of all time. This was an amazing video and enjoyed watching it! Keep up the good work!
I will always defend the 6.2 even if I do agree the hate for it. My 305 and my 454 have had issues along with the old 6.2 I had but that truck (6.2) would start for me no matter what I had done to it, no matter how cold it was and in a c20 23 mpg is pretty good imo
The 6.2/6.5 will always make reliable power. Comparable engines for the year obviously will make more power/durability
I'm a used car dealer, the nearest auction to me is 190 miles away. I got a 6.5 to tow inventory back and forth. Accelerating from a dead stop is painful, but once I'm rolling, I enjoy 15.3 MPG while towing 8k to 11k. I used to get about 11 MPG, but my injector pump quit, and when I pulled the old one, I found that whoever installed it last, put it in with retarded timing. I installed my new one with advanced timing. A bit of knock when cold, but runs fine otherwise.
@@vivillagerif you don’t need much for power or torque then a 6.5 is a great motor and on great platforms, it’s killer is the power as the 5.9 and 7.3 made more power or torque but I’ll die but my old 6.5. I’m actually looking for another with a 5 speed as it sits currently
My '05 Dakota has the 4.7L in it, and it works very well in the mid-size truck. Even tows pretty well, but going up the Cajon Grade it does show its weaknesses. It does some rev-searching when trying to maintain 70MPH unless I completely full throttle it.
I think the 4.7 was put into vehicles that were too heavy for it to really properly handle.
In mountain driving sometimes "overdrive lockout" is appropriate with the automatic.
Try swapping the rear for a shorter geared one.
Just remember with poor performance: the brightest bulb lasts the shortest. A lot of engines used in industrial applications trade power output for endurance.
The EPA hammered the manufacturers until they engineered their way around.
Iron Duke lived on for a long time as an industrial engine.
You failed to mention that the 1976 Cadillac 500 only made that 190 HP in the carbureted version. The fuel-injected optional 500 motor made 25 more HP.
I remember a '66 Chevy 283ci V8 that said it had 195 hp. That doesn't sound too bad after this video. I am thinking the measurement of horsepower in '66 was probably overstated.
There was a change in HP ratings in 1972 when the manufacturers switched to using SAE net HP vs gross HP ratings.
@@edwardpate6128 That’s an important point no one ever really talks about. The best example to use is GM. They were the first to start reducing power output starting in 71. Ford, Chrysler and AMC waited until 72. Their engines on paper took a much larger hit. GM set an 8.5:1 compression ratio limit starting in 71. Their engine lineup from 71 to 72 was basically unchanged. So whatever HP and torque rating differences between 71 and 72 were the difference between gross and SAE ratings.
Under
I just wanted to brag that my 1979 240D has 25.8 Bhp/L which beats the 6.2 diesel.
Well i own a 76 cadillac with the rated 190hp and on the dyno stock was 280hp at the rear wheels. 1k$ in parts with headers, high rise intake and a mild cam took it to nearly 380hp at the wheels
I driven the first gen Viper, it does have a poor hp/ liter. I remember how it has massive low rpm torque.
these are some good videos 🤘🏽. should do a video highlighting the bad parts of some of the ‘best’/popular engines
These engines weren't necessarily bad they just had unreasonable emission goals that choked these engine to death..!
It doesn't take a lot to get 500hp out of a Cadillac 500 you just got to pull the emission crap out of its ass and let it breath through something larger than a 175cfm 2 barrel!
I’m pretty sure all those Cadillacs had a 4BBL quadrajet. They all flow at least 750 CFM. I wanna say actually 850 CFM. All those engines were underrated. 190HP in a car that weighs around 5000lbs wouldn’t last very long because you’d have to beat the hell out of it every time you tried to merge onto an interstate. There are still a lot of these cars left with with over 100,000 miles on them.
Some of these aren't as bad as they sound. The US auto industry switched from Gross hp to SAE Net hp around 1972. So the 180 hp Corvette would have about 250 hp under the Gross rating.
Conversely, when builders and mechanics dyno an engine for comparison, they alway have an electric water pump, no alternator, and no air cleaner or mufflers.
So as soon as they install it in a car, it is making less at the crank.
The 79 Camaro with the 305 V8 made 145hp and the Z28 with a 350 and a Quadrajet 4bbl made a whopping 185. Why weren't they on this list?
I disagree wholeheartedly about the Dodge Viper
Well, the 8.0 magnum, which the vipers engine was directly derived from, has a monstrous 310 horsepower and 450 ft/lb of torque... which frankly is even more pathetic. At the time, it was powerful, but still 38.75 horsepower per liter for the magnum and 50 horsepower per liter for the viper is pretty weak.
@@duckdestroyer2412 Less the displacement, nothing from the V-10 truck engine was in the Viper model. Not a single part. Not even bore and stroke.
That Gen I Viper was only 3,200 pounds too. It was way over powered, thus known as the widow maker. It was a statement car by Dodge.
@TheBeingReal the 1992 8.0 dodge vipers engine was based on the dodge 8.0 magnum block. The bore and stroke of the magnum block exactly the same, 4 inch bore and a stroke of 3.88. It was cast out of aluminum instead of cast iron like the magnum, which was done by Lamborghini. As well as I believe some forged internals.
While not identical, they are basically the same engine. One version just got the fancy parts.
The newer versions are a different story with up boring and added stroke, making them closer to 8.4 liters if I am not mistaken.
The 4.7 from Chrysler was actually designed by AMC prior to the buyout. The only thing the 4.7 has in common with the previous AMC V-8s is being a V-8.
Most of these low power outputs on these engines have to do with engine controls to meet mileage and emissions goals. Engine control systems have come along way since the first electronic control systems.
And since the 4.7 was a SOHC cam engine I'm surprised that Chrysler never seriously looked into swapping the heads out for twin cam 4 valve heads. (1) The 4.7 power output peaked at 310. I'm not sure just how much growth there was displacement wise in the 4.7 block due to the tighter bore spacing. If the block casting had any coolant passages between the cylinder walls it was likely only around .060c to .075" wide at the narrowest point. Also looking at the 4.7's combustion chamber and valve layout I'm wondering if the valve angles were splayed relative to each other. The valves them selves were rotated close to 45 degrees relative to the bore centerlines.
1) Going to a DOHC with a 4 valve head likely would have significantly increased the overall width of the engine. Unless they went to SOHC layout similiar to the 3.5 V-6. Curiously the 2.7, 3.5, 4.0 and I think the Pentastar V-6s all have the same bore spread as the LA and New Hemi V-8s at 4.440" or 4.450". Once you need to cast the aluminum block around the cast iron cylinder liners the block starts to get pretty long.
The 4.7 didnt have much power, but compared to the 5.2 it replaced, it was worlds better in the torque area and fuel economy.
08-13 4.7 would of been 65 hp per liter.
@@OmniOmega0X
I remember when the gold standard for a road car was 1 hp per CI. At least in the US anyway.
I loved the 2.5l in my S10. Wasnt fast, but you could beat on it all day long and it would just take it and come back for more. You can't beat it for reliability.
The 80-81 Turbo Trans Am was pretty sad too.
Finally someone made a video on this, i could never get behind liking engines that have big displacements and barley any power.
I had two iron duke Fieros back in the day. I was able to squeeze a little more power out of one but the redline was so incredibly low it was really easy to spin main bearings. I have always wanted to see how much power I could get out of one if the oil system could keep up.
Not much. Block is extremely weak along with the rods
The Pontiac 301 it was based on wasn't much of a revver either. It's supposed to make all of its power in the low revs and was more suited to small trucks. The Quad 4 is the 4 banger the Fiero deserved with maybe a Buick 3800 as an option.
You should do a part two considering that the bottom end and rest of the car is there and made. Much harder to make all that than do a top end. Exhaust/Intake/Camshafts/Heads
You can't do these videos without mentioning torque.
There's a reason makers kept putting V8s in heavy vehicles even though I4, I4, and V6 power/energy was close, because it's not what mattered or lasted, it's the force
He did mention torque. Lb-ft is torque.
@@HeLpEr4u083 He keeps comparing hp. There's a reason makers kept putting V8s in heavy vehicles even though I4 and V6 power was close, because it's not what mattered or lasted
Have a 2012 Chevy Sonic LS, 1.8 5MT, curb weight 2707. At 83k, zero mechanical repairs, no TSBs nor recalls ever. Not a race car, but I consider it a compact sports sedan. Makes 77hp/litre, (138/125) and 40+mpg, barks tires without intent, gets 0-60 @ 7 seconds, responds with authority and takes 90° turns at 60 thanks to the Corvette-tuned suspension, on cheap Douglas A/S tires (actually made by Goodyear) with 50k run off them. Routine maintenance, simply oil changes and tire rotation every 5k. Unfortunately yet typically, GM retired the durable 1.8 in favor of the now infamous 1.4 turbo option, before cancelling the Cruze/Sonic brothers altogether. Meanwhile, the 1.4T continues to fail in several small GM crossovers.
But the 1.4 without turbo is the base engine on the little Spark.
He thinks the cam in block design is bad. Lol. I suppose he has never heard of the LS ! 😅
OHV isn't bad, its just ancient by todays standards. It'd be like buying a flathead engine in the 90's if it was manufactured, not bad just old.
The Cadillac 500 makes very little HP for its size however the torque is legendary.
It would probably make substantially more HP if it wasn’t strangled with all the anti smog equipment
@@darksaber7678like what
Big issue with the 500 is it would float the valves at around 4,000 rpm.
I don't think this kid ever changed a spark plug in a lawnmower .
When I think of weak engines I think of the absolutely gutless and anemic 1990s and early 2000s Toyota products. Really bad inline 4 that had no torque and sounded like they're dying when you hit the gas. At least those over sized American engines have torque and some type of sound but those Japanese economy engines have nothing
The 4.7l standard output made 230 hp and the high output made 265hp. In 2008 and it made 305hp. You said it never made more than 50hp per liter and that's just not true. The 2008 motor with 305hp is 64hp per liter. I have an 01 dakota with a 4.7 with some mods and it's a solid motor, but I would absolutely hate to have a full sized ram with it. It's definitely too weak of a motor for that big of a truck.
Fun fact: certain years of the ram in single cab trim were faster with the 4.7 than with the bigger engine offered with it.
@@Prestiged_peck hmm do you know why? I feel like if it was the same exact truck only the motor being different than the 5.7 would be faster
@BigIglooUSMC it was offered alongside the 5.2/5.9 for a few years, and also the very late ones were flex fuel and made more power when ethanol was in them. The 4.7 was also significantly lighter than the 5.7 and especially the old 5.2/5.9
Toyotas 4.7 liter single overhead cam V8 from 2000 to 2007 only put out 245 horsepower and it was fuel injected and there was no mention of that. I had that motors in a Lexus GX 470 and it was underpowered.
This. I got an 08 ram. They modified the engine to 16 spark plugs and upped the horses to 305 with some minor mods. Runs pretty decent with 200000 miles
The 4.7 in a 99-04 Grand Cherokee was surprisingly quick, it could beat a mustang up to about 50 mph
Some of these came with a knock sensor and recommended fuel was 91 octane,those I think were rated at more than 235 horsepower.
Would show taillights to an Accurate Honda MDX that supposedly had over 300 hp V6
I had an iron duke s10 that thing was bullet proof never once broke on me and ran to well over 300k miles
My w204 C180 with 156 bhp: Finally a worthy opponent. Our battle will be legendary
Haha, first you think "156hp out of 1.8L isn't bad" then you realize it's supercharged haha
Holy shit stix I'm in your video the 6.2 makes no horsepower I will say but I get like 17 mpg out of my truck and with the turbo I installed it's more than capable at every day driving. Thanks for including my truck in the video!!
2:48 I knew my engine would be on this list. I have it in my 06 Grand Cherokee. It is comically slow for the displacement but, I love it. It sounds great and it is reliable as long as you ALWAYS change the oil on time. An intake really goes a long way with getting more power out of it too.
I'm surprised he didn't talk about the 4.6 from Ford or the 4.8 from gm since all 3 made roughly the same power. I still have my 05 ram 1500 since high school and I love it. It's not the fastest truck but it sure wasn't the slowest lol.
I'm honestly surprised he didn't talk shit about my 5.2 v8 (318), in my 97 dakota it makes 230 hp and 295 lb/ft of torque. But the thing has 240k miles on it and still going strong
The 4.7 high output was alot more powerful
The 5.9L magnum was even less gutless than the 4.7L in the 2002 ram 1500 it only makes 5hp more than the 4.7 at 245 hp
@lethargicstove20 oh yea that's right. But I remember those being a little more torquey than the others. Lol
One of the world's most reliable engine the ford 4.9l inline six in it's worst years only made 100hp.
I had an Econoline E150 cargo van with that 4.9 lire engine and ran to over 300,000 miles and still ran good.
GM’s LF9 is a 350 cu in (5.7 L) diesel V8 that needs to be on this list
A cement mixer motor is probably more powerful than a 82 camero.
I heard years ago that Rolls Royce wouldn't actually say how much power their cars had well into the late '80s or early '90s, only claiming it was "prudent".
but those low hp engines still had great tq numbers, am I right
Having started to drive during the era the Mustang IIs were common and the 1979 Fox body debuted, I have to come to their defense. Ford executives deserve a bit of shame for not jumping to offer something a bit more competitive under the hoods, but in retrospect, nobody was making anything that held a candle to what options a buyer had a decade earlier. The 1979 400 Poncho in a Trans Am was rated at 220 HP and only came with a four speed. It ripped the quarter in 14 seconds according to a Hot Rod Magazine test, beat the L82 225 HP Corvette. Z-28s were optimistically rated at 175 HP if you got the 350. The Dodge Lil Red Truck had a warmed over 225 horse 360 that was in the same ball park as the Trans Am. A 139 HP Ford 302 may have not been a power house, but it was the same architecture as the 289s and could be made to run at least more competitively. The 255 that came out the following year was a dog. Police car buyers in 79 got Ford LTDs on the Panther platform that had a less inspiring 351W 2V that came in varying degrees of tune - all dependent on how hung over the guy on the line was when slapping together the motor. They didn’t have enough power to cause the weak links to handle to come to light - took a redesigned 180 HP 351W Police Interceptor to do that. The 4.7 Dodge was a tougher, gutsier motor than I care to admit. I had one in a company furnished Dakota, hated it, but only because Chrysler’s questionable manufacturing processes for plastic radiator and complete lack of lumbar support in the seats made it the most miserable vehicle I ever operated.
So, here’s a bit of apocryphal trivia.
If the 302 has a 2 piece rear main. A 5.0 has a one piece rear main.
I picked this up in a ford drivability (eec-tach) class in 1993.
You missed the worst one of all time: ford’s 250 ci i6 from the 70s. At its lowest it had 72 hp, which is less than 20 per liter and all of these engines
Can wait tell he sees a Geo Metro
you know blueprints 4 cylinder making 340hp is a iron duke block with a ls head? blueprint bought the mold from gm
1975 AMC Pacer with 4.2L/258ci inline six - puts out 112 hp.
Seriously every single one of these engines just needs a cam swap and a good valve job
I absolutely love this channel.❤
GM Holden in Australia in 1978 had a car called a VB Commodore which had a 3.3 Litre inline 6 that made 89 horsepower. That a whopping 26.97 horsepower per litre.
Parents had a1985 Chevy Conversion Van with a 305cu-in V8
It made like 150hp, weighed like 6000lbs and sucked fuel like a MF and was prone to vacuum leaks all over. They used engine vacuum to power the hvac system! An absolute turd with 100s of miles of tiny, clear plastic vacuum lines that never worked properly.
The ford 255 v8 in the fox body was pretty bad and the olds 260
The worst thing about the 6.2 Diesel is the fact that it makes less hp and torque than the same model year gas 5.7 small block with TBI. The small block made 300 ft lbs in the 91 Suburban. It also made 200 hp.
But the 6.2 has twice the fuel mileage. I own a 1993 Blazer with the TBI 350 and it makes 15-13 mpg. The 6.2 gets 22-30 and diesel is cheaper. You can do a few cheap mods and get the power up to the 200 crank hp mark. But it wasn't built for that. We had the 6.2 in the Humvee in the Army and they were able to perform pretty well with that power to weight ratio.
Too bad Diesel is no longer cheaper than gas.
@@johndemichael1990 Where I live it is.
Oh well that's interesting. Here it's over a dollar more than regular gas. It's more than premium too. By a good amount.

I remember having uparmored HMMWV’s that couldn't drive over a large stick from a stand still, you had to get a running start. Not the worlds biggest fan of the 6.2 and 6.5.
There was a Turbocharged 6.75L Rolls-Royce V8 version used in some models however.
I got a 88 cutlass ciera with the iron duke it’s a great engine
I hope that “blorst” was a Simpsons nod. 😂
Isn't the iron duke what is used in the Grumman LLV?
Yeah, but it’s a more updated model with fuel injection and makes more a little more power if I remember correctly
The thing about those old rolls royces was that it didn't really matter that they were laughably underpowered because they were never designed to be "sporty".
Even bentley's of the era weren't thst much more powerful.
several corrections on the video, i will just pick one- the dodge 4.7 power tech v8. 235hp, standard, 4.7 HO, 265hp/330lb torque, and the revised final gen 4.7, 310hp, 330/335lb torque, and they did not run the 4.7 through 09, it was used through 2013. engine builder, 43yrs in the business. the 265hp 4.7HO was quite the engine, and fast in the jeeps, and the last gen 310hp 4.7 with cold air kit and a tune would fist fight a 5.7 hemi.
I’ve never heard anyone say “there’s no replacement for displacement” I always heard “there’s no substitute for cubic inch” I like yours better
Anything under 70hp per liter is disappointing, if turboed under 90hp per liter.
They made the 4.7 all the way to 2012 in the ram. It’s built more for towing which it did well but it has the valve seat issues, head gasket leaks & timing chain issues. Sometimes you’ll get lucky with them and they’ll last 300k or sometimes you won’t.
I’ve had customers that owned a vehicle with the 4.7 with over 300k and some that didn’t make it past 50k and a majority of the ones that didn’t last the maintenance wasn’t done properly
Most likely using additives like Marvel Mystery oil or Lucas Oil, that's one way to help any any engine extend its life
Dont forget that in 1972 HP ratings were changed from gross to net, so when you compare numbers across this line your results aren't as bad as you make them out to be- Im not denying there was a loss of HP during this time, but some of the differences in your comparisons are artificially inflated.
The 500 Cadillac engine made 400 horsepower pre smog controls. The later ones made so little due to the EPA.
You've obviously never heard of the GM 253 v8. 120 horsepower off the factory floor
uhhh, major, major addendu. to the 4.7.
the 4.7 ONLY made 235hp from 1999- 2007. past that it was more of a high output variant that made 265 hp, and was used until 2008 and past that a even higher output model that made 310hp was used until it was discontinued.
My first car was a 75 Chevy Monza with the 4.3 liter V8, and a whopping 110 hp. Insult to injury was the gymnastics needed ro change the back spark plugs.
Imagine it’s 1986 and you’re driving you’re pretty new corvette and get fucking walked by a 6.9 idi pulling a trailer
there is one car i forgot what it was but it had a 5.7 NA diesel V8 with 105 hp
Aircooled vw engines, Yugo's blistering 45 horsepower, whatever hampster wheel is powering Trabants, etc etc
90s 454 Bigblock TBI 215hp 430tq - less then 30HP/L
Im not going to complain about your coverage on the iron duke. Yes it was enemic in power and torque but as far as reliability most likely even today the usps uses a variation of it in their mail delivery vehicles
Zero historical context here.
400HP was amazing in 1991 when the Viper was introduced, didn't matter that it took 8 liters to get there, everyone loved it. Only thing that was close was the ZR-1, believe it had 375 HP to start and later 405 HP, and that carried a much higher price tag than the base Corvette.
The Iron Duke was a Pontiac motor, at least you got it right the 2nd time. And you really show a lack of understanding of that era 79-82, times were bad. There was a recession, interest rates reached as high as 21%, gas prices were high, unemployment was high. 60s era cars that are valuable today were put in the junkyard during this era because there were not buyers for them. The racing scene was not what it was in the 60s/70s, although it came back to life in the late 80s. There was a market for a 4 banger Camaro in those days. They also offered the 110 HP 2.8 V6 in the early/mid 80s Camaros.
You don't think the 1980 Corvette should have been produced because of the 180HP rating? Well, Chevrolet sold 53,807 Corvettes in 1979, an all-time high! Yeah, I'm sure your opinion would have carried a lot of weight in the GM board room back then.
The Cadillac 500ci 190HP is just an product of it's era. 360 lb/ft got those boats moving, that's it. Side note: the 500ci Caddy responds very well to modification.
The 6.2 diesel was also a product of it's era, people were amazed at the time that you could get 20mpg in a full sized truck. Diesel was also generally less expensive than regular unleaded in those days, further increasing the utility of choosing the diesel engine. And they generally lasted a long time with good maintenance. If you want to contrast this with the other American OEM's, Ford introduced the 6.9 IDI in the mid-80s (86 IIRC) and it wasn't much more powerful. Dodge had no diesel option until 88 or 89 and when they brought the first gen 5.9 ISB, it had 160HP, IIRC, and that was WITH A TURBO. But nobody would dare put a Cummins ISB on the "worst engines" list, would they?
My idea of a worst engines list would be things that were unreliable, regardless of horsepower rating. Cadillac 4-6-8, Chrysler 2.7 Sludge motor, Oldsmobile Diesel, and so forth. These engines you mention are just a reflection of the technology level of the era that they were produced in.
I had an 05 ram 1500 with the 4.7 great engine for what I used the truck for, could tow decent, but damn I didn't like to hold power going up hill unless you slam on the gas the whole way, very under powered
I knew that 305 was going to be on this list a very hard to modify or work with the block and heads,aftermarket forget about it and I'm a Gm fan
Had a 1976 Lincoln with a 460ci. It was pretty gutless.
You could put the cat 3208 and the Detroit diesel 8.2 fuel pincher on the list for medium duty trucks
I see the engine all the time in busses & it’s usually low mile stuff cuz it’s a trashy engine. Worse than the IDI. The 8.2 did come with a turbo but it was prone to head gasket failure, & just a weak engine.
3208 was decent but still pretty terrible.
Awesome channel bro, I didn't know the 6.2 diesel was that weak, 4.3 v6 Chevy is stronger or just as strong as the diesel. Lol
Fun video. And yes I get a laugh out of the old diesel die hards that though those old diesels werre the cats meow. More like the cats bowel movement. You know the type: "Yep, there's nothing that can beat that old 12 valve Cummins".
5:35 thats a weird speedometer, but Its kind of cool at the same time.
As a 6.5 owner a hx35/40 turbo swap and a tune on 94+ model years it actually keeps up with a lb7 duramax
1983 ford ranger 2.2 Perkins diesel, 0-60 mph in 1 minute.
The iron duke still lives on in grumman LLV mail trucks.
Definitely that thing gm did with I believe a Buick 350, turned it from a gas to a diesel. It was a mess, bad engine, etc.
I had an ‘85 Crown Vic (grandpamobile) with the 5.0CFI that was pretty gutless
Chevy Chevette. The one RCR reviewed made 39 horsepower
I had an '82 VW Jetta Diesel with the 1.6L. 52 HP, 0-60 in like a week and a half. Still turned in 50+ mpg tho...
