The 340 Dusters and Darts had one of the best power to weight ratios out there.
True!
My brother-in-law had a new 1969 Dart GT Sport 340 automatic. He beat everything on the street.
One day he raced a 429 Ranchero on the perimeter highway just outside Winnipeg. The Ranchero had wide tires and the Dart had narrow factory tires.
The Ranchero took the Dart off the line, but was less than a car for length ahead. All the way down the highway, the Ranchero did not pull away at all.
My brother-in-law said that if it wasn't for the wider tires on the Ranchero, he would have beaten it. That GT Sport was an exciting car! It was gold with white vinyl top and white interior. We listened to Creedence Clearwater Revival on his factory 8-track in the car.
@@Spunky-iq8jm The Ranchero had wide tires because otherwise he would have sat there spinning and your Dart would have walked away from him.
High revving little torque monsters. My brother bought a new 1971 Plymouth duster 340 4spd. Pure stock with the addition of headers he would routinely run High 13's in the quarter. This was with the plastic body Carter Thermo-quad carb!
@@Spunky-iq8jm he was probably smoking a doobie doing it
Thank you for the Commentary!! I love the videos, the Mopars, and the creative comments that just make it all work.
Thanks!
Back in 1976 my brother-in-law owned a built 70 340 Duster 4-speed in Wilimantic CT. That car was fast as hell and held it's own against most big block muscle at that time. Awww the memories...
Even though it gave up 115hp, the Duster held it’s own. Those 4.30 gears kept it in the running. Those 340s are badass.
Yeah, but those in-the-know, we know that 340ci small block was probably more like 360-375hp from the factory... very underrated for insurance purposes and to dodge the emerging emission laws.
@@johndeeregreen4592 absolutely. Chrysler hardcore underrated ALL of their engines. A humble looking brand with a mean hidden side
@@johndeeregreen4592 Agreed 👍
factory rated hp numbers have no meaning as none of the cars on this channel are as-assembled from the factory 50 years ago.
@@mjs28s, it gives a clear indication of gains from the modifications allowed by the rules. Nice try, Mr. Smarty pants.
My two favorite Mopar engines - 440/6 and the 340. And man what a race - certainly no turkeys here. Thanks again - Happy Thanksgiving 🌮 🌮
🌮
Ah yes! Love both of them. The Duster bring's back fond memories of the '72 Duster 340 my older brother bought new. Same color and funky interior. That car was so fun. The Runner, what can I say, several friend's owned them and they were hot. Mopar fan for life.
*OH MY FUCKING GOD THIS IS MY FAVORITE VIDEO ON YOUR CHANNEL NOW!!!*
seriously, I love classic mopars, especially Dusters and Road Runners!!
Thanks 👍
My cousins BF replaced his Chevelle with a 68 RR 383 4sp. She liked it so her parents (my aunt and uncle) got a second car for her to drive to college, that’s right, 68 RR 3sp auto black on black. Well cousin eloped a couple of months later and my aunt became the only librarian at Fordson HS driving a RR.
2 bad ass cars! It’s amazing just how potent that “little” 340 really was. Hilarious video as always!
Thanks for watching 😎
My first car 1978 was a 72 Plymouth Cuda 340 it out ran all my friends, cars a 1970 SS 396 Chevelle, a 71 Camaro 350 easy, a 71 Pontiac GTO, a friends 1970 Mach 1 Mustang 351 I beat it only by a half a car length. A 72 Javelin 360 a friends 71 Mustang 302 and a friends 74 Pontiac Firebird Formula 400 on the interstate
Plymouth vs. Plymouth! Incredible machines and drag times. I totally love the A12 RR and that "pocket rocket" Duster prettily shows why it's called a muscle car killer. Fantastic duel and I add it to my playlist.
I had a 68 roadrunner 383 automatic and my buddy had a 69 dart 340 with 4 speed. Both cars were factory stock except for a few comparable bolt ons. I always beat him but not by very much. His car was a lot more fun to drive than mine, though. This video made me very nostalgic. Well done.
thanks for watching 👍
I had a 69 383 automatic Roadrunner that car was awesome
That is one nice a body while everyone loves the b body's I had a duster and it hurt a lot of feelings with the dog dish hub caps no chrome 340 4 speed 83/4 rear I had fun on the street!
Going on leave after a 8 month deployment on our Destroyer, my buddy gave e a ride back to Louisiana from Norfolk. He was also a Louisiana native. We left Norfolk and the speed limit back then was 55. We got stopped about 20 miles out of Norfolk by a full grown Virginia Bear and he issued a warning for 85 in a 55. He called ahead to clear us and we were never stopped again even though we averaged about 80 mph all the way home. You talk about a quick trip in his 1970 340 Duster. He had replaced the cam and the intake and carb set up with Holley equipment and other goodies. That 340 would just hum through those duals. It was a crazy, fun trip especially since we had some special help staying awake.
Ha! Great story
I was surprised that the 340 still had its higher compression ratio and hp rating in 1971. From the dyno runs at Nick's Garage a stock 340 was closer to 315-320 hp..
It had dropped a little for ‘71, but still impressive
I believe I have an old Hot Rod magazine (circa 1971) where they dyno'ed a 1971 340 demon at 335 HP. I forgot the Torque numbers. I'm gonna see if I can find it.
You would think the 440 has it but those 340s sometimes really run
Goodday C & Z,
Perfect timing for me whilst having my Thursday afternoon lunch break at work.
Mopar Or No Car
Happy Thanksgiving wish you all the best to you and your family & friends.
What else is there to say ,
2 beautiful Mopar's is all she wrote.
340 vs 440.
Your number 1 Fan in Australia
Louis Kats from Melbourne Australia ☺ 👍 ❤
2 of my favorites making a fantastic pass
Your opening comment was shockingly spot on,lol. You wernt joking about both being maxed out according to the rules.
That said, I figured the Duster would be ahead at the 1/8th but the hp/to of the 440/6 would take the win.
That was the quickest Duster I have seen in this class. Almost a giant killer.
My friends grandmother had a 72 Duster when we were kids in 82. It was ready for the junkyard and it was only 10 years old.
Absolutely georgious
Awesome C&Z《☆》A win/win for me watching 2 fine Mopar specimens on display👍👍Happy Thanksgiving Brother🖖🤓🏈
🦃
I almost bought that exact Road Runner back in 1982. I was 20 minutes late 😢
The Dusters were so light. I surprised a lot of guys in Mustangs and Camaros in my 318 Duster. Had a couple of minor tweaks but mostly stock. Off the line and light to light it was quick! Would have loved to put a 340 0r a built 360 in it.
This winner was expected even with the RR weight penalty BUT, BUT the lil Duster ran strong with those 4:30 gears and 727 torqueflite
The crap I'll put up with to see a great race!
I seen that A12 and nearly creamed my carrot!
I give thanks today for Cars and Zebras brilliant jokes and excellent drag racing coverage.
Keep up the good work!!!
The 340 was underrated more like 320-330 horsepower it wasn't enough to beat the 440 but the 340 gave him a close run the race turned around about 3/4 track making the 440 play catchup
That was a good race between two great Mopars.
My 71 Duster 340 w/ factory Carter Thermoquad loved to eat big blocks.
Mid 70s I raced my 69 Roadrunner against a 340 Dart. Blew him out of the hole but he almost caught me at top end. Those 340s could wind.
So many things (cars) to be thankful for! And Zebras 🍺 🍻 Cheers!
Cheers 🍺
Going for the A12
"It takes a Mopar to catch a Mopar."
Actually, I am not on the toilet, I'm in the bathtub. So there!
Just had to comment and say "jello"... Great video with a couple of beautiful classics. Wondering the builds and were they running "yams".. ?? Oh well... impressive video, history of the cars, and great commentary. Btw.. thanks for not giving us "the bird".... 😅😅🤣🤣🤣
Damn man. You called me out regarding my “viewing” room, place & time. The Sharts are very underrated. Great flowing heads that don’t fall on their face at high RPM’s. Light and well balanced. Those Big-Blocks don’t transfer the weight to the rear that well upon launch, so nose heavy. WELL DONE C&Z!!
I'm a Mopar man cool cars
You called me out 100% in the beginning of the video was doing exactly that
I'm not a mopar fan by any means but these are 2 of them I actually like.
Definitely cool cars
Happy T-day, C & Z!!
🦃 🍻
Thanks for the duster vid whoo hoo!!!!
The 340 was known as the giant killer because it beat Chevelle 396, Camaro 396s. They tend to beat larger cubic inch motors from Chevy and Ford.
Awesome , Thanks C&Z
🍺
@@CarsAndZebras 🍗🍺
'69 340-S fastback cuda 4 speed DAMN I wish I still had that car!! So much fun watching car after car on Whittier blvd. try and die! Small block big block didn't matter didn't win them all just most!
Well ONE Mopar ain’t gonna catch the other Mopar. My money is on the Duster.
My Money is on the 340 car too, Since Big Block Mopars have a Horrendous Win/Loss Record on this channel.
Pay up!
@@jamesthomas7977 Yeah the Big Block FINALLY Won a Race, and just Barely, i give the 340,s credit. Shouldn't of been that close, with Hundred more cubes.
Thanksgiving☺ us a great content! Great job with editing and your best! Yes i had a 71 340 Cuda 72 340 charger and 72 340 demon with a built 1970 340!!! Those cars could run👍🏻
@#$%^&×* awesome cars! Awesome race! I got a chill when the RR chirped 2nd! You guys prolly won't believe me but, on the way to the stupid Walmarts today I saw a freakin Super Bird! I didn't have a chance to go ck it out, tho. It was Hemi Orange. It was sitting out front of a little rinky dink garage. It was missing the tail lights and so bright and shiny, I would bet money it just got painted. Super Birds were not uncommon back in my day. (40 years ago)Some maniac that owned a motel used to have 2, just sitting out front of his place. We have a yellow one that attends charity car shows and I saw a blue one, in a guys garage, a few years ago. Corpus Christi makes my eyes misty, lol!
Actually I just finished in the toilet before watching this. I hope I didnt break any protocol today.
By the way, those Dusters sure seem to be competitive.
Love watching these classics run. Thanks for the vids, you have a great day today zebra guy.
Heads up racing right there.🏁
I love those Mopars
Happy Thanksgiving !!
Happy thanksgiving!
Same to you! 🦃 🥧 🍞
Happy Thanksgiving!
Great cars and better puns...very "PUNny". Happy T-day C&Z and viewers
Yo man how did you know I was on my toilet, that's a little unsettling😳
💩 🚽
I love the Duster!! So yeah, f'em!!!
Unfortunately I lost my male cousin who died in a Plymouth Duster crash in the early 1970's . Sad : (
Too Funny. Happy Thanksgiving everyone!
happy thanksgiving 🥧
@@CarsAndZebras You too! Thanks for the laughs with great matchups!
I literally was guilty as charged,, even avoiding the family,, but I couldn't stomach the puns....
I figured it would be close... I'll bet the Roadrunner was sweatin' a little bit! lol....awesome race, the 340s from '70-'71 were no joke! The color on that Duster, though....no thanks.
DUDE!!! 99% correct!! Sept it's easter.
Much respect to the Duster
Holy crap. I thought I turned my camera off. Did you see me?
Happy Thanksgiving
No loosers in this race because it truly does take a mopar to catch a mopar
Is this Happy Punsgiving?!
Comments: 340 340 340 340..
Yes, a fabulous engine, especially in the perfect home for it, one of the A body Mopes.
However!!! If you were staring at one and next to it was an A12 road runner & you could get either for a song...??
Yeah..you'd so snap up the 'runner.
Dude is there any 68 RR on the strip ? I’m dying to see one ☹️
I’ll have to look at my footage over the years, but I’m not sure if I have any ‘68s
Love all the Fart sounds and Humor two Awesome Cars !!!
👍🇨🇦 Happy 🦃 day
👍
I had what most consider the plain Jane of this :) the car they made the duster out of lol
MY MONEY'S ON THE DUSTER !!!!
I keep hoping @cars and zebras will screw up and post a video of my car 😂
Someday. I’ll just not show the engine and tell everyone is a never-touched original. Then they can pee their pants at the ET.
@@CarsAndZebras Works for me...I'm running out of nether regions which have never been molested :)
I've been called out as I sit on the shitter watching this.....
Must have had the forward cam on on the phone
Who's doing the tuning on these cars to make them run those kind of times , especially without slicks or headers , all the years I've watch pure stock racing it was very seldom you see these cars run mid 12s especially a stock 340 with just a set of gears , tell me I'm wrong !
Scott, check out the description of this video page. It has the rules for allowed mods. Shift kit, ok. Electronic ign, ok. 1.5 point raise on comp ratio, ok. +.070" over bore, ok. On a hot day the surface of that drag strip can be like glue. I've seen people leave a shoe stuck on the surface, if it wasn't tied securely enough. It gets sprayed with "stickem".
@@mrkemblegilstrap, Martin 131 is an awesome track. I grew up 20 miles from there and it's always been world-class in it's maintenance and setup. Often times, my 383ci Regal would run mid 11s there but only mid 12s at Stanton... all because of how good the crews and track is at 131.
@@johndeeregreen4592 that's awesome, buddy! Back in my day you would be one of the dreaded "Buick Boys"! Lol! Seemed like everybody either had a Buick or a Mopar. There were a few of everything else. I do have a fond memory of a 70 Stage 1, tho. Every time he did a burn out, his license plate would fall down then slam shut, lol!
@@mrkemblegilstrap They only allow for a 1.5 point increase in compression but just the blueprinting and dyno tuning alone is worth quite a bit in actual, usable power. What gets me is the ability to launch with those skinny bias ply tires. If you put the mph/weight of the car through a calculator the 340 is only making 273 to the wheels and the Road Runner is only making 371. Truthfully, if you've seen dyno tests of these engines stock that would be about they produce in top tune and ideal conditions without any increase in compression. These racers are just getting 100% out of their engines where most people over the last 50 years, including me, were lucky to be getting 70% out of their muscle cars.
@@1967davethewave hi! Hey, thank you for the correction! I went back and edited my post. I sure went crazy on that one! Believe it or not, I usually make very few mistakes. Yeah, for giggles, I've run a bunch of these times/mph thru a HP/Torque calculator. Parasitic losses on Auto/Manual tranny are pretty interesting. I had a 3 grand stall in my Bee and I could feel the looseness in it. Personally, I think 4.30 and 4.56 rear ends are kinda useless. IDK why people are so afraid of numerically high gears. I see so many of these cars that run a mid 13 at 107. A 4.89, like my bee had would take a whole second off of their time. How many car lengths is that? I am very impressed with the times some of these big block cars turn in with the street tires. Great drivers and great track. A stock small block with a auto doesn't have the low end power to have any traction problems.
Hmm, exactly what I was doing....🤔
💩
By rights, the Road Runner should smoke the Duster. I owned a 340 and a 69 Road Runner 383.. and the Road Runner wasted my 340 Duster.
If that were Cars and Zebras Duster 340 the license plate would read BICURIOUS, I know, that's over 7 letters though.
I smell a stroker in the duster....
Roadrunner SHOULD win but…
I Love You.
My first car was a Duster but it had the slant 6. Wanted a Charger but my brother talked my mom out of buying it. Said it was too much car for me as a newly licensed driver at the age of 17. He said that I would kill myself with that car. Woulda kicked his ass but he was 6'6" 250 and I was a 140lb pipsqueek, so that wouldn't have worked. Oh well, 6cyl Duster it was 🤣😂🤣😂
Phenomenal video!!!!! Check out my 1968 Barracuda fastback powered by a 512 stroker backed by an A833 4 speed manual. 👍
Another WOT video.
I will Tell All the Duster Hater's, If I still owned my 74 340 4 speed 390 rear, Built to 569 hp 503 foot pds, Best not race me, Back in 80's I was Beating everything, 9.80 143mph I beat more big blocks than I can remember. By the way it was a six pack.and that was in early 80's
340 is definitely faster than stock
I like the Duster, but that’s probably mostly because of Al Bundy.
What happened? Did you fart so bad everyone else left the stands?
No, it was probably just because 2 Mopars were racing, Not really a fan favorite i guess.
Taco Tuesday 🌮
Mopar vs Mopar it's a win win
road ripper...beep beep..
When the Road Runner grabs 4th gear....buh bye.
Could you possibly talk and tell jokes more?
Loved the cars, the youtuber/narrator needs to get over himself and the 3rd grade humor.
Would have been better if both cars had been original.
The A12 Roadrunner as far as you can tell in a video was completely stock.
The Duster however, while appearing stock did not come with 4.30 gears. Lowest available factory option i can find listed for that car/engine combo was
3.91. Doesnt seem like a big difference, but would have been enough to take away launch the duster got on the Roadrunner and would most likely have slowed him down enough to put him over the 13 second mark.
@robt3305. CORRECT! On all points! Thank you
😂 commentary 😂
Good info and race, but all the stupid stuff in between made this video nearly unwatchable.
Way too immature to listen to
First
my father had a Duster not 340 (sad) but 318......second worst all around car i ever drove (behind a Chevette).......horrible brakes even in an era known for horrible brakes.....replaced it with a 350 Chevelle.....much better
I like watching the competing classic muscle cars but can't stand the guy who is putting them on. His sick fart jokes all the time get old fast. Having said that, I lived those muscle car times and drag raced my 72 Dodge Demon 340 while my brother raced his 67 440 GTX. I can tell you that none of the cars in these videos are factory stock. NO muscle car of that era could come close to running 11 and 12 in the quarter mile, especially with skinny stock tires. All I can say is that the NHRA rules for what they consider (stock) tells me that they are anything but stock. Back in the day no car, even the Hemi cars, would not turn 12's bone stock. You needed slicks, headers, and great tuning to get there.
