Both engines were grossly underrated. The Boss was closer to 500 horsepower and so was the 426 HEMI. I recently saw a video where a rebuilt to a close to stock as possible 426 HEMI denied out at 495 Horsepower at 5800 RPM. Like I said, under rated.
That’s amazing 🤩 💯
I wouldn't show so many pictures of Oddball motor stuff when you're referring to the Hemi motor stick to just hemispherical motor pictures please
Thank you for taking the time to respond I highly appreciate your opinion
@@HighHosilver I was not trying to be a smart alec I just pay attention to details
Thank you for it, this is the kind of engagement I appreciate.
Ok, after reading all the comments, all I can say is that I sure am glad that all these motors and cars were there! We grew up in an unimaginably awesome time! I feel very blessed to have grown up in this amazing country in the 50’s, 60’s, and 70’s. It’s like a problem of riches.
The Hemi's carbs were over 1000 cfm while the Ford was only 715. The Boss motor was starving.
That’s an amazing fact
Thank you for sharing this 💯
426 Hemi was always slow on the eighth mile but would come alive and catch up on the final stretch. 440 and others would gap it on the eighth.
Absolutely 💯
Thank you for your insight
Challenger came out in 1970 , not 1966, 67,68, for the end of 69 they were starting to be advertised and ordered but would be titled 1970.
It’s all in the story my friend and thank you for your comment

From what I remember, the Boss 429 was a disappointment on the street and the dragstrips. If you sunk a boatload of money into them, they may have been competitive, but out of the factory they were not very impressive vs the hype they received. Maybe I'm wrong, but.....
The Nascar engine was different from the street version because Ford had to put it in production in order to use it in stock car racing
It’s all in the story my friend and thank you for your comment
Absolutely 💯
You are correct.
The 429 suffered on the dragstrip because it was built from NASCAR they later found that out
I'd take either, just need to win the lottery.
I know them both and love them both. If I were asked to choose, I have a simple answer, I'd take both.
Absolutely 💯
The 426 hemi used solid cam from 64-69. 70-71 hyd cam. The street hemi is not same as race hemi. It’s designed for shifting at 7200 rpm. Go look up the ASE engineer paper Chrysler turned in. The 426 hemi is a nascar engine adapted to drag racing. I have bunch of 426 hemis. You should redo this video and get your facts at 100%.
Absolutely right 💯
It’s all in the story
The cylinder heads on the BOSS 429 are aluminum ... not "cast iron".
the intake ports on a Boss 429 are large enough to park a truck in! i don't know what engine this guy is talking about! He is right full of BS! the Boss cars where Faster than the Hemi until Dodge came out with an Aero package. NASCAR Stopped Ford from using there Streamline cars. The reason the Street Boss was not as potent as a hemi Ford detuned the engine to make sure it would last on the street.
Would have been cool to see the OW43 Oldsmobile 455 hemi in the mix! Yeah, I know. I wasn't aware they made one, either! Never hit the production line but I guess it was quite a beast!
Absolutely 💯
And thank you for sharing this.
Boss 429 was disappointing. So was the 429CJ. Good results were achieved with the CJ valves fitted to the 429 PI head and port matched to the CJ intake. I'm kinda of a Ford guy, but without a ton of work, I'd pick the hemi.
Absolutely 💯 and Thank you for your comment its highly appreciated
The street motor was a Semi Hemi not a full hemi. It had a quench or flat areas on eather side of the Hemi dome whitch stoped it from being a full Hemi dome . And the coments are correct the heads are not cast iron .
Absolutely 💯, it’s all in the story
Thank you for your comment
Brutal how many mistakes are made when describing the engines.
You are welcome to share your insights, and thank you for your comment
@@HighHosilver I don't know Where you got your information from but, whoever told you the Ports in a Boss are smaller than a Hemi must not ever have looked at a Boss 429, the Boss port is the largest port ever used on a Production engine bar none. The street Boss was built to homologate the engine into the NASCAR rule book. The Street hemi was built to win at NHRA drag races. That is why the Boss is mild and the Hemi is Wild.
Road racing?? Even in the US those engines hardly got a look in. Most tintop road racing has been 6 litre limit [366ci]
Absolutely 💯
The real appeal, as always, is scarcity. Ford's BOSS 429 and Chrylser's Hemi were low production volume engines at the top of each manufacturer's line up. Many Chrysler performance cars are worth a little more than their cross town rivals all these years later because few were sold originally and as a result fewer survive to this day. Low production engine options make the cars that have just that much more valuable years later. It breaks down pretty easily and predictably. Virtually any Barracuda or Challenger from back in the original Muscle Car era will fetch more money than a Mustang or Camaro this is most comparable. Really rare high end engine options close the gap though in many cases. The BOSS 429 Mustangs are a good example of how this works. An L88 Corvette or ZL1 Camaro also highlight the few Ford and Chevy cars that fetch the bigger dollars along side those Hemi Cuda's and Challengers.
Thank you for taking the time and comment I highly appreciate your input and urge #everyone to check it out
It's a shame, as time goes on, these presenters doing videos of these legendary engines that are part of racing/high performance history get more and more of the information wrong.
These experts that got it off the web somewhere else.
These mistakes get passed along through these videos to the people who believe EVERYTHING that's on the internet, and soon many of the truths about these pieces of history are lost forever.
Effing Shame.
Was ford 429 a hemi never heard that before. Far as I knpw it was not hemispheric combustion chamber on ford.
It’s all in the story my friend and thank you for commenting
Yes it's a hemi
Mopar actually patented the Hemi name, so Ford couldn't use it, despite having hemispheric heads. They wete sometimes called "semi-hemi" or "crescent" heads too.
Fun fact: you can use 426 Hemi connecting rods in the Ford Boss 429.
Not all 429s were hemis. The 429 scj was not & the 429 thunder jet was not. The 429 boss was a hemi
Also the ford 427 sohc was a hemi.
Put a good set of heads stock ported ,or john kase heads.the dodge pos hemi will get destroyed. The 426 hemi is extremely aggravating to work on with the plug design and thousand dollar headers that dont even fit the mopar engine bay made for the slant 6.better off with the ford or a big block oldsmobile or chevy.
You lost all credibility when you said "pos dodge hemi"...
I gave you a Like out of pity.
Absolutely 💯
Big chevies blew o. The track,,so therefore. The BBC is a ship anchor, p.o.s. as well
