Always a great way to fire up some pirated film of the Hurst Hairy Olds rolling around. Even if that footage is permitted under Y T's Byzantine rules, its not right. Its theft. Period.

The 409 was a grenade motor. It was a strong runner but almost every race there was a problem with the engine rod hammering and and many other things.. the true horsepower was Ford's 390 engine trypower which put out 401 horsepower and it would do it all day long.. towards the end of the 409 GM started to get it right and the engine would last but that was many years later... To the honor goes Ford motor company...😮

You missed the famous for failure Chevy Vega engine from the 1970s.

MY 62' CHEVY BEL AIR'S PLATES READ... "SRFM409"👍🏻😎

The 283/283hp fuel-injected engine was among the first of the American engines to offer 1 horsepower per cubic inch of displacement in 1957, five years before the 409/409 "Milestone".

"Posey Traction" OK Bot voice.

While I've never owned a 409 I did have the chance to own a 348 in a 61 impala bubble top car. I was 17 years old at the time. Black with a nice red interior. If only I knew what they would be worth now 😕

Favorite 1970 GSX Buick Stage One 455ci.

Take it from a 30 year Chrysler Tec. The Chrysler 2.7L and 3.2L were two different designs. The 2.7L duel overhead cam run by timing chains. The 3.2L was a pushrod engine. The 3.2L was only offered for 3 years in the LH cars and was dropped for the larger single overhead cam 3.5L. The 3.2L was also used in minivans and Jeeps for over 20 years. The 3.5L and later 4.0L were a great engines and had very little problems. The down fall of the 2.7L was that owners didn't change the oil. It had a 3k mile oil service interval that was necessary do to the low quality oil used at the time. Anything would sledge up if you are going 10K on an oil change on conventional motor oil. If you kept the oil clean you could get 200K out of one.

Computer generated A.I. voices just too annoying. I can't finish watching.

The Ford 5.4 2V spark plug issue can be mostly solved by torquing the plugs to 25 ft lbs (use no thread lock).

I My self Marvel at how some clueley people Can solve the problems of the triumph V8 engine

Get a real voice. "1970's". Fail. Also we don't say F150 the way your bot does. You included the Triumph that sold like 100. But the 1971 -1974 Vega engine is skipped.

As he is talking about how bad the Ford engines are, showing a nice red truck, at 16.33 you hear a phone ring tone, seems the truck was making a call for help.

Yes up keep of the engine is the best thing for a long life. There are always problems with the engineering of engine design.

The Buick 231 v6 is awful. The rods go bad after 100,000 miles due to poor oil pump design. Had an '83 Cutlass and original engine went bad. Replaced it with another one that was used and same thing. Knew other guys who had Cutlass cars from the 70s with this motor, and they all said the same thing, bad rods.

Evidently you never heard of the Triumph TR 8

We turn them jags into jagrolets out of them with a 350 sbc easily installed ! still a piece of crap, but now it starts and runs every day

A.I. Generated BS...for clicks

Most are just planned obsolescence designs created when accountants dictate engineering 😮

Not ugly !

I think it's unanimous the caddy engine is the worse

Awesome to hear from the early 60's Muscle Era !!!!!!!!!!

"The Ford F one hundred and fifty truck" was dead giveaway Mr robo. LOL!!

BMW V10 and Porsches from early to mid 2000s are really awful

I've got personal experience, with almost every one of these engines. The Olds diesel, was at it's worst in 1978. They did not have heavier blocks, until 1979. My dad, had a 1978 88. Not only were the engines bad, they put the turbo 200 transmission, designed for the Chevette, in them. I worked as a mechanic, in an Olds dealer in 1980. They had an entore bay, filled with complete diesel engines, for warranty replacements. I had a 2001 Eldorado, with the Northstar. They came with an 8 quart oil pan, because they burned 3 quarts of oil, between oil changes. We were told, if the low oil level light comes on, pull into any GM dealer, and they will fill it for free. Their excuse was they were built loose, to maximize power. Lol. A friend of mine, made a living for a couple years, rebuilding Chrysler V6s. The problem with them, is the water pump is inside the engine. If the water pump failed, the coolant dumped into the oil pan, or, if the timing chain stretched, it jumped teeth, and the valves struck the pistons. He would go to the junkyard, and buy heads. He would disassemble them, and take all the straight valves, to replace bent ones. He coud buy the cars, in good condition, with bad motors, for $300-500, buy parts for $150, and sell the car for $3,000. My brother in law had an F150, with the 5.4, that blew the spark plugs out, from bad threads. The problem is, bad engines don't show up, for a few years. Don't ever buy a new engine design. Another one, is any Ford turbo. They all blow eventually. I made sure to buy my 2024 Ram truck, while the proven Hemi was available. I know those issues. All 2025s have turbo 6s, which are not proven yet, and will probably be as bad, as Ford turbos.

Do you know why the British drink the beer warm? They have Lucas refrigerators. ;-D

What a joke! The Northstar was a LOT more reliable than the HT4100, which you didn't bother to mention. Fail. Try again. But if you can't do better please give it up.

Yeah, man ! That 409 was the precursor to the 396, 427 and the 454 and that Impala with a 409 was to be feared. The most common of the Impala was small block V-8 powered. That was a decent performance car, but the "fat motor" and it's TONS of torque was pretty bad ass !' Thanks for the memories ! I am getting old enough that my memory needs to be jogged a little, LMAO ! Of all of the 409 Impalas, the 1963 was my favorite...I was lucky enough to have a friend that had one so I got to drive it quite a bit.

Nothing sounds like a 409 reveling up!!😂😂😂😂😂😂

Talk about a blast from the past! These 15 muscle cars are like a time machine straight back to the 1970s, when horsepower ruled the streets, and the soundtrack was the roar of a V8. Who else is getting major nostalgia vibes?

These 1970s muscle car commercials are a trip down memory lane! 🔥 The raw power and iconic designs of that era were perfectly captured in these nostalgic ads. If you're a fan of classic American muscle, this is a must-watch! It can help us come back to good memories.

Wow, 😁😁😁 I didn't realize how bad the Cadillac V8-6-4 was. It's interesting to see how advanced technology for the time ended up being its downfall. Goes to show that innovation without proper execution can backfire.

It's crazy how some of these engines had so much potential but were ruined by poor design choices. The Triumph V8, for instance, could have been a classic if they had just ironed out those cooling issues. It’s a shame!

GM and Chrysler continue to use cylinder deactivation, but it's proving to be just as problematic as before. The uneven heat generated by this technology is actually leading to premature engine wear.

Forgot about the mystery motor.396 and the 427... the 427 mystery motor has the same bore and stroke as the w 427 Z11

1970 SD/HO 455 was nasty

I can tell a lot of effort went into this video-thanks for creating such quality content! This video bring me back to good memories.

6:40 Wow....its a "Pozi" Traction. A.I. Bullshit.

This is the kind of video I’d recommend to everyone! So informative and well put together.

I didn’t know I needed this video until I watched it. Thanks for the inspiration

The way you explained this concept is pure genius-so clear and easy to follow!

Looks like some some more fake ass A.I. sh!t coming up.

To. Bad. The. 429. Ford. Out. Ran. All. Them. On. Top. End. Talladega. Race track

Thank you for taking us back to the good old days. I really enjoy hearing these historical stories😁😁😄😄

1955 Chrysler 300 is often recognized as the first muscle car. However, its high price meant that only a small number were sold. Despite this, it made a significant impact by dominating NASCAR for a few years

04:00 WOW Arguably, the most distinctively stunning engine ever created for a muscle car.

Outstanding documentary on the 409 engine! Your hard work is truly appreciated. The muscle car era as we know it today wouldn’t exist without the 409. A huge thank you to Chevrolet for their innovation and contribution!😁😁😁

You can tell its ai by how the numbers are spoke

Funny, torque on these engines is not any more than the 400 sbc
