- 1969 Mustang BOSS 429 & 1970 Dodge Challenger R/T 426 HEMI Muscle Car Of The Week Episode 301
Today, we’re taking a look at two Muscle Car Icons… a 1970 Dodge Challenger 426 Hemi Convertible and a 1969 Ford Mustang BOSS 429. We’ve shown each of these cars individually, but chose to look at them together this time to see how these two very different cars both rose to the top of the Muscle Car ladder.
The Challenger was marketed towards the upscale, personal luxury crowd, even with the 426 HEMI engine under the hood. Challengers are comfortable and feature-rich, looking to edge out the Mercury Cougar in the marketplace.
The Mustang BOSS 429 was an entirely different animal, developed as the street-going carrier of the NASCAR-bound BOSS 429 V8 engine. It was a big project, as the giant Boss ‘9 engine didn’t fit in the stock Mustang’s engine bay, so Ford worked with contractor Kar Kraft in Dearborn, Michigan to make the necessary modifications to accommodate the big 429. Redesigned front sheet metal was needed to move the shock towers outboard so the Kar Kraft team could install the engine. Every extra inch was needed, so the battery was moved to the back of the car, which also helped shed some weight off the nose. The front suspension was tuned up with different springs and a stiffer sway bar to manage the additional weight, power, and performance of this specially built Mustang.
On the other hand, the Challenger’s engine bay was designed to accommodate the 426 Hemi headed V8 from the beginning. The car was a fresh design for 1970, and one of the goals was to be able to fit any of the Chrysler engines under the hood, from the long slant six up to the 440, and the 426 Hemi was the widest of the bunch by far. The Challenger is 4.4 inches wider than the Mustang, but even so, the Hemi is a tight fit. The 426 Hemi is another engine that had to be sold to the public to remain legal in NASCAR racing.
Driving these two cars are very different experiences, with the cushy Challenger winning on a comfort and ease-of-operation standpoint. That wider body means more room inside, and amenities like power steering, power brakes, torque-flight automatic transmission, AM/FM radio, and a full gauge package in the dash make it an easy driving ride.
The BOSS 429 is far more high-performance in feel, with manual steering, a 4-speed manual transmission, but it did have power brakes and an AM radio. The suspension is stiffer on the BOSS, and we believe it was also the first Mustang to receive a factory installed rear sway bar.
While the 426 Hemi was rated at 425 HP and 490 pound feet, the high-revving BOSS 429 was only given a 375 HP rating, and most consider that a low-ball. Both engines had huge valves and free flowing combustion chambers that liked high RPM usage, and both are easily modified to significantly raise their power output.
These cars are at the pinnacle of Muscle Cars for all the right reasons… high power, low production totals, with 857 ‘69 BOSS 429s built and only 12 ‘70 Hemi Challenger Convertibles, but they are also valued because they are just really cool cars. And while they really don’t compare from a function or market standpoint, we thought it would be fun to share two of the most drooled-over cars from The Brothers Collection in one episode.
While nobody could have predicted the astonishing values of these cars decades on, we have no doubt that people recognized that were both very special cars!

Tough call, I like'm both. In situations like this, my advice is to go with a 2 car garage.
TheGunfighter45acp Good advice! 😆👍
Or better yet, a three car garage for a Camaro with a 396 or 427.
I'd agree
@@jacobeakright6387fuck you
Amen brother!.. That is of course if the ex-wife hasn't taken that option away from you by way of undeserved alimony, then you should absolutely enjoy them both!.. And If not you can always take the kids away from her because she'll always appreciate them way more than the cars!. 😉😉😂😂😂😂
That BOSS 429 is definitely my choice
I love both but the 429 is one of my all time dream cars, and that red is just amazing.
I love them both. But if I had to choose one I’m taking that Boss 429
Very beautiful car both of them but if I had to choose I would take to hemi convertible being worth over 3 million dollars versus the boss only being worth about 300000
The boss 429 was overrated, slow, and pathetic, according to my uncle who is a mechanic, if it were me, I’d go with the 428 SCJ mustang or the chevelle SS with either the 454 or 396 big block V8s
@@Jack-yw7bq - ya boss 429 dominated Nascar 68, 69 so much Richard Petty went to race for Ford he was tired of losing. Your uncle doesn’t know Jack
no dodge better
@@Jack-yw7bq 429 made 500+ horsepower stock. He doesn't know jack shit about cars
I’d take the 1969 Boss 429
I like the Boss429
Love'em both! I'd have to lean to the Mustang. The Boss is just a beautiful engine and with a 3.59" stroke, that's one factory big block that's not afraid to rev.
Mustang Boss 429. But I would be happy with either one of these beast. 🤓
I'd pick the 9, but the R/T is awesome.
I love both but that 429 Boss is just awesome looking
The Challenger is beautiful, but the Boss 9 Mustang is my choice here. .
The Boss is my choice
I'll take the BOSS
like a boss
I’m a mopar guy but the 429 is far more rare than a hemi. Never seen one in good shape fetch under 200k. The challenger convertible tho, that’s a unicorn. It’s around 500k. With both being numbers matching, of course.
Why not both?
@@malikmcdowellswreckedatv5100 1970 hemi Challenger is rarer than a boss. 287 hard tops built. Only 9 convertibles... not 12 and one year only. No 1971s. This car is north of $2 million dollars!
I agree the Challenger Shamed the Boss’s name
Boss 429 all the way!
I’ll take the boss 429
I would take the BOSS 429 all day.
The Mustang!
ABSOLUTELY 👍💯😊
I'd usually pick a Mopar over a Ford, and a Hemi E body is incredible, but the 4 speed wins out. I'd have the Boss.
Boss 9 all day long
I'll take the Boss everyday! BTW, I've driven both a '70 Hemi Cuda and a '70 Boss 429 when they were new back in the day.
We're the time machine parked?
Lucky bastard!
We elders of performance car days didn't know how good it was when we were Young!
Motor City Mike. so true it was a great time to grow up I had a 1970 442 with the w30 that I payed $700 dollars for,back then it was no big deal can you imagine , my girlfriend totaled it but it was no big deal these kinds of cars were everywhere in 1976 when I got my license
@@rockiemountin7535
Such a different world......
1969 MUSTANG!
Give me the BOSS!
Mustang, all day every day.
The Mustang best looking muscle car ever made. And had the balls to back up the goods
Love them both, but I especially love the fastback look.
Tough choice but I'll go with the Boss 429.
Both sick whips; But I’d take the Boss 9 every day of the week and twice on Sunday!
The boss 429 all day
Love them both but its the stang for me
I'm getting old, I remember both cars when they were new. I liked the Boss then and would still pick it today.
The Boss . But love them both.
With performance being similar, I prefer the looks of the Mustang. A Hemi Cuda hardtop would have made the decision more difficult.
My new Charger looks similar to the Boss. Agree?
@@dalepeto9620 No, not even close. For starters, Dodge made the new Charger a four door. It doesn't even look like the old Chargers, which were two door cars. My ' 13 Mustang GT more resembles the old Mustangs, but are a little fatter. But then again, I'm fatter than I was back then as well.
A stock Hemi Cuda or Challenger would beat a stock Boss 429 by a pretty decent margin in the 1/4 mile. The Hemi E-Bodies ran very low 13's but the Boss9 ran low 14's. A 428 CJ Mustang with a 3.91 or 4.30 rear can beat a Boss9 in the 1/4 mile so a Boss9 doesnt have much of a chance against the Hemi. At least not in stock form. Lose the smog pump, install a bigger carb, headers, and a more aggressive camshaft and ignition curve and the Boss9 is an absolute MONSTER. A completely different car with just those few mods
@@jeremythompson9122 I agree the Hemi was much higher tuned. In stock trim it would easily outrun the Boss. As prepared for racing they were very close. That's why Chrysler went to the winged Daytona and Superbird.
Jeremy Thompson the Boss ‘9 isn’t, and never was a drag engine. It would run all day long compared to some others, as we all know it was designed for use in nascar, not drag racing. The logical choice for Ford would have been to put it in the Galaxie, but logic doesn’t generally come into play with performance cars...they wanted to have some fun with it. A Boss 302 would outrun it on a road course, and a Boss 351 would beat it in the 1/4, but the 429 just has that extra bit of mystique.
The Boss 429. With a 800cfm carb. 1970 429scj cam. No smog pump and 60,000 volt ignition system. 1970 lighter rotating assembly.
That's exactly how the BOSS 429 should've left the factory
You need to disconnect the rev limiter , too .The 1969 had all the O rings in the head and it was very hard to r&r the heads in the car . The 1970 was easier and they also changed from the S to the T connecting rod . Rod length changed .
And get rid of the semi hemi heads for real hemi heads like the race versions had
And cut the value in half by doing so
I had a Charger from that year and I really loved it. The Challenger I always liked but the luxury of it was kind of a turnoff. For that matchup, and I'm a MoPar man here, but I'd have to go with the Boss 429.
Although I love both models. And I can only pick one. I will take the BOSS.
1969 Ford Mustang Boss 429 👌🏻😍❤️
I'll take that 429 any time of the week! Looks great
Don’t like convertibles but would take the Boss 429 any day.
The Boss for me! My first new car was a 69 metallic blue 351 Mustang fastback. Bought it right after I got out of the Navy. THAT was a car and those were the days!! Would love to have them both back🌵
I will take the Boss 429 please.
Semi hemi boss 429 all day!
I'm building a 408w sn95! Love your channel
@@CanIbeFrank Thanks! I wish I could find more of my videos! Soon to come 427 stroker build...once I find another cobra...
I love both of these cars and the rag top does give a few points to the mopar, but the mustang has the correct name and is the BOSS!
Mustang will always be BOSS !!!
Yeah, the Challenger R/T was more swank, and the Boss 429 more of a brute....but I'm not so sure about the comfort/luxury comparison. The Boss 429 in this video has the upgraded interior, virtually the same as the Mach 1. It was actually quite plush by musclecar standards and the seats are often regarded as among the best of the era, comfort-wise.
Boss 429 simply beautiful
I gotta go with the manual transmission.
The Boss 429 had the pedigree and hardware, but a stock one wouldn't fall out of a tree. A well tuned Hemi would back up the reputation it had.
Hemi was a mutt on the street just the same, although slightly less. The hemi also dual quads while the boss used a teenzy 735 Holley while the baby B302 had a 780 Holley, funny huh. The exhaust manifolds are anemic on the 29 compared to the hemi as well, thanks to the shock towers. Cam specs were also tame. The B9 head with the monster intake port is more suited for a 460+” engine minimum not a 429. Give the boss the setup it deserved and it’s taking that 426’s lunch every time. It was a bad combo on fords part, not the engines fault. It easily would have been the top gun muscle car had ford done it justice. All just to try to make it more “streetable”
@@mitchanderson5813 I agree with you. The Boss 429 could have been the hottest muscle car ever built. The hardware and potential were there. As you pointed out Ford hamstrung the engine, with the intake, cam and exhaust. The 426 Hemi was also finicky and had to be well tuned to run its best as I said in my comment. A 440 six barrel did also. A well tuned Hemi was bad to the bone. And that was without replacing parts. No amount of tuning would make the Boss 429 run like the Hemi without changing some of the parts you mentioned.
I'll take the BOSS 9 any day .
Damn. ..tough choice , i absolutely love both of these cars , but if I can't take both of them I'd have to take the Boss 429.
Can't wait to have my '70 Challenger in as good a condition as this one.
Both great looking cars though I'd the challenger
Challenger for me, horsepower ...
1970 challenger is my dream car😎💪
Nothing could ever beat a Hemi if you ask me
Boss 429 for me!!
I want a 69 Mustang boss 429 I hope while I am still young enough to still drive it
Save yo pennies lol.
BOSS 429 !!!
All Day!!
BOTH ARE ICONIC AND AWESOME!!! The DODGE being a convertible, makes my decision EASY.
Wouldn't you love to open your garage to see these beautiful cars in there.
i be honored to own either one. that mustang looks fast standing still.
BOSS 429 hands down!!!!
Hemi Challenger. But both are awesome old cars.
The challenger looks confident
Boss is just something else 😻
Of these two cars on the video, Mustang w/o doubt.
Kevin, this was the best episode of MCOT I’ve ever seen. Well Done
They are both lovely. I'd go for the Stang.
BOSS Everytime
Both beautiful cars but I’ll say this about the 429 engine. It made Richard Petty switch to Ford in NASCAR.
Challenger.
I really have great love for BOTH cars. My favorite would be the Mustang for my favorite year of Mustang styling, plus the more performance-oriented vibe of the car, as well as the color. Now if it was a Lime Green 1970 Challenger T/A with the 340 versus this Mustang, that’s a much-tougher call... Always a GREAT show, and well-narrated. Thanks very much.
Boss9 for me
Boss 429 my pick
I'm a mopar man and had a 70 roadrunner, Coronet Challeger and now have a beautiful all original low miles 66 Charger.
VERY hard decision but for me the Boss 9 takes it by a hair.
Love the boss! That one awesome car
Boss mustang [ i hate the gear reduction starter on the dodge] 68 torino gt 428 scj thats my pick !!!
The Boss 9 Represents a VERY COOL wall to wall Hemi in One of the Most Beautiful non Shelby Mustangs of all time ! The iconic 69 sportsroof !! YES....
By they way it not a Hemi unless it is built by Chrysler as they trademarked the name. It is just called hemispherical combustion
@@noneyabusiness7053 Hemi= Hemispherical combustion Chamber. So what's your point?
I owned Boss 429 KK2034 for over 30 years. I ran it with the original "820-T" factory engine and headers, later putting in an actual Holman and Moody spec NASCAR 429, with one of the twenty Super Stock (Mickey Thompson Drag program) original two four barrel intakes. The original motor was probably around 390 real flywheel horsepower - 735 cfm Holley and mild cam signed off at 6,000 rpm - the Boss 429 Mustang was, as noted, only sold to the public to make the engine legal for NASCAR. The HM NASCAR motor would easily keep pulling hard way past 7000 rpm (where I limited it), and with a 4000 lb car, full gas tank, me (250 lbs) would run 122 mph quarter miles on too small 10" Goodyears (that slide rules out to about 650 HP). Bill "Grumpy" Jenkins (of Chevrolet Pro Stock fame) after examining the design, stated it had more potential than ANY other big block engine - and Bob Glidden proved that - with years of domination of NHRA Pro Stock with his Thunderbird, and it had at least 50 horsepower over the 426 Hemi on the Super Speedways - which is why Chrysler built the Daytonas and Superbirds - to make up the shortage in streamlining. By the way, the Boss 429's were invoiced directly to Shelby American on the window sticker - which ticked off Carroll Shelby since they competed directly with his Shelby GT-500.
Awesome road car, very comfortable and handled surprisingly well for so much forward weight. Miss it I do! Mike
I'LL PICK THE FORD MUSTANG BOSS 429!
Mopars are my Favorite, but I would take that Mustang as well! I’ve always heard that both motors were underrated... My family had them both & a lot of others... We still have a few in the Family as well... Nothing in stock form though. I think y’all should put them on the dyno!!! Have Fun!!!
Mopar or no car
Oh boy . 2 awesome choices . Great video as usual !
69 boss, without pause or hesitation!
BOSS
Boss 9, all day every day.
either one for me...both cool. somebody was having fun in that parking lot...great backdrop to the vid with all the burnout stripes!
The Boss, always wanted a Boss 302 but got a 66 GTO back on the day
I would choose the Boss 429. Always been a Mustang fan.
That's easy. The Boss 429.
I’d take both but if I had to pick I’d go with 69 Mustang!
69 Boss 429 without question.
Boss 429.
Boss 429, hands down.
Both cars are highly underrated as far as power is concerned
Triple black boss 9 🤤🤤🤤🤤🤤
I'd go with the 429. 4 on the floor, aggressive looks, and sporty performance. Not to mention the functional hood scoop is wild, and the fastback lines beat the Challenger's drop top.
Had the Challenger been a different colour, different transmission, and different body style, it would've been a much closer match. A Hemi Orange R/T looks amazing, but had the Boss been Grabber Blue or even Raven Black, it would've made the decision that much harder.
69 Stang for me!❤💪🇱🇷
Thats a Liberian flag not America.
Cars were so cool back then. The shiny chrome everywhere makes them look so premium.
two racer brothers in my town bought a 1970 boss 429, brand new. then they pulled the motor for their gasser and sold the rest as it sat on the dealers lot. no joke. hermansader brothers, hamburg pa.
Just for STYLE. The 1969 Mustang BOSS 429.👍👍👍👍👍
Thats my Dream car.I could have bought one in 1975 2,200 from a friend.I wish I had know.
Boss 9..its very good looking muscle car.
I'd choose the mustang
omg, boss 29, every single time...
