Exactly the same consistent times my 1970 Duster 340 ran ... 14.2s all day ... but that was with 10.5 compression so I’m guessing this one was rebuilt to ‘70 spec.
This is a pretty good matchup...the 3.08 gears I think, really hurt the Firebird. The times for both actually seem believable.

@@bhaggen I had a 72 Dodge Demon that I had purchase in 1976 that the previous owner had put it on a Dyno and it made 340 Hp. When he stated that, I said you must mean torque and they tested it on a raceway and it ran up to 132 mph top speed (Oval Track), I had the Demon up to that speed on a stretch on a highway on RT 1. Even though it was a Dodge, the motor was Plymouth Blue. My Demon was a four speed with a 3:91 rear. That was my favorite car of all time. I purchase for $1,650 for a four year old car.

You don't understand Poncho power. Pontiac 400s are done by 5000 rpm. They make a lot of mid range torque. It isn't a Chevy that can use some deep gears. Put 3.73s in that Firebird and you will slow it down. He can either tune to the 3.08 or find a 3.23.

Great video! That firebird had pretty steep gears, I bet it would run alot better if the gear ratio was lower, although I've never had any trouble with putting the hurt on some GM big blocks through the years, I've always loved my 340"s that's why they call them the giant killer. 😀
I'm going Demon w/3.91 - 3.91 GEARS!!!! & TorqueFlite 3 speed... Seems like under rated HP/torque figures but I'm a Firebird RAM Air fan over the Demon. My guys gonna loose
I had a 71 demon 👿 canary yellow with black racing stripes I had a good rear end and good gears, 340built, put it on a diet, and it became the big block killer 💯
I know that the 71 Demon had a stronger engine than the 72 but people in here are saying that the 70 340 was faster I had always thought the 71 was the strongest 340 I know that having the right heads makes all the difference I had a 74 Challenger with a 71 340 and it was quicker than my 440 Challenger!
Great turnout for the event lol! Dodge Demon 3, Firebird 0 despite the Semon being down 90hp to the Pontiac. It's the little engine that could! I had a gold '72 w. a 4 speed and 3.91 gears. Flip the air cleaner lid over for ram air and an easy 10hp. Mine would outrun anything under 400 CI on the street. Even beat a 454 Corvette in a stoplight drag race.

@@ghostrt1608 Pontiac V8s are just Pontiac V8s. The difference between a Pontuac 455, 400, and 350 is no more than that between a SBC 400, 350, and 302. Displacement and deck hight changes but they're essentially the same engine. The only reason Chevy has big blocks and small blocks is because they had 2 completely different engine families at the same time, one big and one small. Same with Mopar big blocks and small blocks. Two completely different engines sold at the same time.
I had the 400 HO engine in a GTO. The HO engine had a bit more cam than the regular 400 (but not as much cam as RA3 or RA4). Combine that with a 3.08 rear and it's a poor combination. 3.55 needed at the very least. I had the 3.55 with the wide ratio 4 speed and it would leap off the line.

Back in 1978 in high school I almost bought a dodge demon dart for my first car. Thankfully I ended up buying a Pontiac 69 GTO. 400 , auto with 3.55 gears. Way better looking car with plenty of power. A guy at my high school had a 1970 340 Duster. He had a small cam, headers, thought it was fast.

1/29/2024: My 1972 340 Challenger didn't have any balls. No HP & No Compression, But I did like it. My 1968,69,70, 440 magnums Did. "Station Wagon" Rear Gears on the Firebird. Good temperature & humidity for traction. Best Regards from "the future".

I've owned many Pontiac's and many Mopar's and love them both. The Bird needed more gear and would have been a closer race. That Demon ran good for low comp
see what a 3:08 rear end does for you? Even the smog mobile Demon with a measly 8:5 to 1 compression beats it. At least he had 3:91’s to push it over the top barely.
You don't think it's still running it's 8.5:1 compression ratio do you, it will probably be running 1.5 points more in accordance with the pure stock rules.
@@Welcometofacsistube sure it is. It was one of the ways mfgs met emissions control at the time. Anything with power before ‘71 had decent compression. for a prepared pure stock car it ran poor times as did the FB shown.
@@Welcometofacsistube Any car you see on this channel that is part of Pure Muscle car drags is built with additional compression - pretty much guaranteed. Reviews from the day show that Dodge is capable of accelerating from 0 to 60 mph in 6.7 sec, from 0 to 100 km/h in 7.1 sec, from 0 to 160 km/h (100 mph) in 17.3 sec and the quarter mile drag time is 15.2 sec...
14.50's with 3.08 rears is pretty good. With 4.11 rears the Poncho is a high 13-second car all day long but then it would be on a trailer like the Demon instead of out on the highway cruising.
Factory 4:33s in that 8.2 rear and yeah, that Bird would take flight ! My 68 bird Covert 400 runs in the low 12s with 4:11s with Turbo 400 trans and it's waaaay more heavy .
Weather forecast for today: mostly sunny with cool temperatures at 50° and a very gentle westward wind at 5 mph. At the end of the race we can also expect a brief shower of tears from the Pontiac fans, possibly progressing into a flash flood.
I drove my friend's '71 Demon 340 at the dragstrip years ago. It ran nearly identical times 14.1 to 14.2 @ 97mph. Mostly stock, column shift automatic, 3.23 axle, HE 268 cam in 120k mile, otherwise stock engine. No nitrous wanted or needed. If there had been nitrous you would have heard it in the audio.
That was all on the driver of the bird... reaction time not the greatest.. look at speed , bird has it every time.. getting off line slow... fun to watch these cars..😊
I whip out my giant chicken tender. Your eyes widen with anticipation. "Wow, it's so thick" you exclaim, mouth watering. "Yeah, I guess it is rather filling" I reply. Little do you know I'm about to pull out a plate full of biscuits ready to be devoured.
340 ''A'' body hold there own with anything and that's a fact! This is NOT coming from a mopar man . I have wrenched on 3 different pontiac 400's (68,73,76) and was never impressed with there power which is weird because I know a guy with a 1966 389 pontiac which is a smaller version of a 400 and it runs like a scalded dog. Not running down a 400 either all I am saying is after doing some mods to one I was expecting a lot more than it offered but it seemed like a good driving/running engine.
The mid 70s 400 Pontiacs had 7.6:1 compression. No mods will do anything until you bump the compression up to 9.5 or more. The 389 probably came with 10.5:1
@@timsharpe3498 The 389 was also tri power. The 68 Firebird 400 my boss had that I wrenched on had no power but I am thinking now maybe when it was rebuilt it had low compression slugs put in the barrels.
@@wildrosegarage4208 Pontiac Tri Power systems are mostly for show. A factory Quadrajet setup flows better. Same for the Corvette tri power setups. The intake runners were very low profile to fit under the stock hood.
@@timsharpe3498 True but they offer even distribution and the guy with the 66 gto has now switched from tri power to a throttle body efi system and says it was way faster with tri power. I think it was a stupid swap the coolest thing about the car was factory tri power.
Always wondered why according to the cubic inches it wasn't the same horsepower at least it's too bad too that's a 340 with 200 and something horsepower that blows should have 340 horsepower then that puppy would get up and scoot. Either way I'm sure it's no slouch those 340's we're pretty quick especially the ones that were before this one two or three years back.
It has soft gearing because they spec'd it for cruising. There. Figured it out for them. That's a truely stock car not one built to class rules like we often see here.
Duster and Demon 340's have to be close to maximum bang-for-the-buck awards. That Demon driver needs to quit staging until his opponent pre-stages though (not very nice....).
I'm betting that they are rare due to 1. Low resale value ( back in the day ) 2. High insurance cost . 3. High cost of O.E.M. sheet metal 4. Rapid corrosion due to poor factory standards .
Nice job by the Demon but a pathetic performance by the Firebird. The car is 60’ ing like a turd due to the freeway friendly 3.08 rear gear. Car should easily cut 3-4 tenths with a decent rear gear.
Il na aucune justice dans ce drag,ce n,est pas la même catégorie d,autos,un big block avec un small block,taux de compression,j,aurais bien aimer ca qu,il s,aurait pogner avec mon dodge charger 383 magnum 1969 ca saurait pas passer comme cela,et les moteurs aurait plus semblables,je suis sur a 100 pour 100 qu,il aurait pas été en avant,les pommes avec les pommes et les oranges avec les oranges.
In the left corner the Phoenix rising from the ashes of Pontiac. And in the right corner the car with a name so diabolical it scared the shit out of Christian groups in the 70s Let's get ready to Rumbleeeeeeee!
I have to agree with Lunch pack, I like older cars just for the fact that they had style, I guess they r like people in some ways....they don't have much style either & the cars b4 the 80s didn't all have a big computer running the thing, carburetor, motor,transmission,alternator, batter & a big ass gas tank!! Those day were fun, but its always fun to waste a lot of fuel l& make la lot of smog. Just not really a good thing today. We r living in New times now & we about to pay the price for being so God damn stupid.
They really screwed the 340 up with the smog crap an the government sticking their nose in the automobile business, Chrysler came out with the 360 that replaced the 340 ran one with the 360 an smoked him with my ,70 340.
The definition of what’s allowed to be considered pure stock I’ll tell you right now these times of the stock vehicles doesn’t match up to the real deal back in the early 70s. A 14:00 wasn’t something all kuldip do. See where I’m going with this
14.2 from a "stock" demon- not likely. Takes around one HP per 10 lbs to get to 14 flat. Oh and its not lbs ft, its ft lbs. on par with the metric system.
I've been 12.40s with a 3.23 gear and a Q-jet. If had has the stock 12" convertor that is his down fall. I picked up a 1/2 second by going to a stock convertor to a PTC unit in one of my cars with a low compression (8.1) Pontiac 350.
Pontiac crybabies coming in 3...............2................1........... Expect the dislikes to be insane on this one. Pontiac guys cry on every video on this channel even when there's a win.
I'M GOING TO LEAVE A DISLIKE BECAUSE I'M A PONTIAC FAN AND THEREFORE ACT LIKE IN A VERY IMMATURE MANNER. I CANNOT SEPARATE MY LOVE OF WATCHING THESE VIDEOS FROM MY DISLIKE OF SEEING A PONTIAC LOSE AND THEREFORE WILL DISLIKE THIS VIDEO ENDLESSLY. NO CURRENT YOUNG PERSON EVEN KNOWS PONTIAC USED TO BE AN AUTO MANUFACTURER SO I'M GOING TO USE A CONDESCENDING TONE DESCRIBING THE NON-SUPERIORITY OF PONTIAC. I'M SURE THAT WILL HELP GARNER POPULARITY FOR THIS EXTINCT BRAND AND DRAG RACING IN GENERAL. WAHHHHHHHHHHHHHHHHHHHHH. I NEED A DIAPER CHANGE.

see what a 3:08 rear end does for you? Even the smog mobile Demon with a measly 8:5 to 1 compression beats it. At least he had 3:91’s to push it over the top barely.
You don't think it's still running it's 8.5:1 compression ratio do you, it will probably be running 1.5 points more in accordance with the pure stock rules.
@@bunter6 yes because it runs pretty slow times!
No factor 8.5:1 compression 340 in 72.
@@Welcometofacsistube sure it is. It was one of the ways mfgs met emissions control at the time.
Anything with power before ‘71 had decent compression. for a prepared pure stock car it ran poor times as did the FB shown.
@@Welcometofacsistube Any car you see on this channel that is part of Pure Muscle car drags is built with additional compression - pretty much guaranteed. Reviews from the day show that Dodge is capable of accelerating from 0 to 60 mph in 6.7 sec, from 0 to 100 km/h in 7.1 sec, from 0 to 160 km/h (100 mph) in 17.3 sec and the quarter mile drag time is 15.2 sec...
14.50's with 3.08 rears is pretty good. With 4.11 rears the Poncho is a high 13-second car all day long but then it would be on a trailer like the Demon instead of out on the highway cruising.
A low compression 340 still is unbeatable. Love them mopars
Firebird wasn't tuned properly. Ran slower than showroom stock every pass. It left the line lazy even for 3.08 gearing.
Awesome , Thanks
Firebird lost because he has 3.08 gears. He would be in the 13's with a set of 3.73's.
If the firebird had some decent gears in the rear it would come alive . The demon even at the 8.5 compression still does good
Factory 4:33s in that 8.2 rear and yeah, that Bird would take flight ! My 68 bird Covert 400 runs in the low 12s with 4:11s with Turbo 400 trans and it's waaaay more heavy .
Weather forecast for today: mostly sunny with cool temperatures at 50° and a very gentle westward wind at 5 mph. At the end of the race we can also expect a brief shower of tears from the Pontiac fans, possibly progressing into a flash flood.
Great fucking comment.
Cars are a good even match, nobody blew anyone out of the water.
I'm quite sure that near full point rear gear ratio was the deciding factor.
That 3.08 rear gear of the Firebird really hurt it's performance!
That was a pretty matched race for 2 very mismatched cars.
They called the 340 a big block killer for a reason
@@user-yv1bf4rx7r Pontiac never made a BB.
The PMD has 3.08 highway gears, the Demon is deep with 3.90s, almost a full point rear axle advantage.
Don't see many Pontiacs losing to mopars.
308 was a handicap.
Those aren't the correct manifolds for a 400 HO, it should have the cast header type.
I hated dusters and demons they were freaky fast
Not really fast... just quick.
Because I didn't tune the PONTIAC!
Mopar power on display. Another 340 slaying a big block.
You're kidding, right?
What BB?
Because Pontiac never made one.
@@soldierski1669 ...well a 340 Mopar killing a GM engine which has 60 extra cubic inches...
Looks like the Mopar was cutting the light better than the Pontiac
Also the PMD has highway gearing.
Bring back the snarky commentary please
340 !!!!
Don't care, still LOVE my poncho's! Glad to see the demon worked out whatever was going on in the first time trial, it was definitely off-pace.
Old firebird 400 hard to beat with 4.10 's...
The actual hp of a 68 Firebird was about 400
Horsepower
3.08 gears are just killing the Firebird's potential in the 1/4 mile.
I think the mechanical problem the Demon was having in time trials was his nitrous solenoid wasn't working.
I drove my friend's '71 Demon 340 at the dragstrip years ago. It ran nearly identical times 14.1 to 14.2 @ 97mph. Mostly stock, column shift automatic, 3.23 axle, HE 268 cam in 120k mile, otherwise stock engine. No nitrous wanted or needed. If there had been nitrous you would have heard it in the audio.
It's the rear end gearing , demon just right another few feet the firebird would win ,as it was traveling faster
The 340 is a screamer! Chevy, pumpjack, Ford couldn’t touch em! Maybe a Mopar 440 that’s it
Yep the 3.08 gears hurt the Pontiac but the “72” 340 wasn’t stock either.....😒
And that '72 340 doesn't have to be completely stock
without seeing a photo finish I'm not buying it
That was all on the driver of the bird... reaction time not the greatest.. look at speed , bird has it every time.. getting off line slow... fun to watch these cars..😊
Reaction time has no effect on ET.
The compression ratio killed thr 340
1972 ... not exactly a banner year for muscle cars. 8.5 to 1 compression ratio!?! 😣
When the octane rating of pump gas plummets that's natural
I whip out my giant chicken tender. Your eyes widen with anticipation. "Wow, it's so thick" you exclaim, mouth watering. "Yeah, I guess it is rather filling" I reply. Little do you know I'm about to pull out a plate full of biscuits ready to be devoured.
Wrong site. Just go to google and type in something about 'adolescence with zits'...I'm sure you'll find a good support group.
I’ll eat your chicken tender
@@badgerbait8351 imagine that, badger bait is here complaining again. What a surprise....
Look how slammed the Firebirds are in the brochures! That's some false advertising right there. They sat more like 4x4's.
Who'da thunkit?!
340 ''A'' body hold there own with anything and that's a fact! This is NOT coming from a mopar man . I have wrenched on 3 different pontiac 400's (68,73,76) and was never impressed with there power which is weird because I know a guy with a 1966 389 pontiac which is a smaller version of a 400 and it runs like a scalded dog. Not running down a 400 either all I am saying is after doing some mods to one I was expecting a lot more than it offered but it seemed like a good driving/running engine.
The mid 70s 400 Pontiacs had 7.6:1 compression. No mods will do anything until you bump the compression up to 9.5 or more. The 389 probably came with 10.5:1
@@timsharpe3498 The 389 was also tri power. The 68 Firebird 400 my boss had that I wrenched on had no power but I am thinking now maybe when it was rebuilt it had low compression slugs put in the barrels.
@@wildrosegarage4208
Pontiac Tri Power systems are mostly for show. A factory Quadrajet setup flows better.
Same for the Corvette tri power setups. The intake runners were very low profile to fit under the stock hood.
@@timsharpe3498 True but they offer even distribution and the guy with the 66 gto has now switched from tri power to a throttle body efi system and says it was way faster with tri power. I think it was a stupid swap the coolest thing about the car was factory tri power.
@@wildrosegarage4208
I spanked plenty of triple carbs with my plain old 4 barrel. Not as cool but my main concern was low ET.
If the firebird were a manual the chances could have been better with that rearend
I wish they could bring back affordable muscle today
Big Block Pontiac ... little 340 don't have a chance
No such thing as a Big Block Pontiac
Always wondered why according to the cubic inches it wasn't the same horsepower at least it's too bad too that's a 340 with 200 and something horsepower that blows should have 340 horsepower then that puppy would get up and scoot. Either way I'm sure it's no slouch those 340's we're pretty quick especially the ones that were before this one two or three years back.
Park that Firechicken and find out what's wrong. Ugh, and I am about done reading these comments. Some of you guys need to actually buy a car.
It has soft gearing because they spec'd it for cruising. There. Figured it out for them. That's a truely stock car not one built to class rules like we often see here.
Well, it was fun while it lasted. But clearly, Cars and Zebras has been hijacked by a very special breed. Bye!
No one cares if you leave, drama queen.
Breaks my heart.
Duster and Demon 340's have to be close to maximum bang-for-the-buck awards. That Demon driver needs to quit staging until his opponent pre-stages though (not very nice....).
You = 😭
That rear gear killed the firebird
25,000... I'll take it
Damnit no fart jokes....
You know why mopars are rare?
They couldn't sell them when they were new
I'm betting that they are rare due to 1. Low resale value ( back in the day ) 2. High insurance cost . 3. High cost of O.E.M. sheet metal 4. Rapid corrosion due to poor factory standards .
@@pippendog1 right! That's why they couldn't sell them when they were new
If it was a 71 340 it would have been 275 plus hp. 72 gov. De tuned everybody
Nice job by the Demon but a pathetic performance by the Firebird. The car is 60’ ing like a turd due to the freeway friendly 3.08 rear gear. Car should easily cut 3-4 tenths with a decent rear gear.
I disagree, considering it has a 3.08 rear gear that is a very impressive quarter-mile. but you can keep being a pessimistic d-bag.
The Bird is gonna eat a Demon . Did not think the Demon had the power i was wrong .
Il na aucune justice dans ce drag,ce n,est pas la même catégorie d,autos,un big block avec un small block,taux de compression,j,aurais bien aimer ca qu,il s,aurait pogner avec mon dodge charger 383 magnum 1969 ca saurait pas passer comme cela,et les moteurs aurait plus semblables,je suis sur a 100 pour 100 qu,il aurait pas été en avant,les pommes avec les pommes et les oranges avec les oranges.
Taking a public poll. Who is the worse fanbase..... Pontiac Firebird/GTO fans, or Corvette people?
Trick question it is a tie
How about CHILDREN who seem to have to compare MUSCLE CAR brands like WWE wrestler's. My gawd, grow up.
@@edwinfeldman8231 right...... so you’re a fan of Pontiac and Corvettes?
@@lunchsack6861 Sack I gotta give it to ya man I really didn't like your first comment but dude, that second one made me spit beer!
Better get rid of the spare tire, tire iron, & throw out the back seat!
In the left corner the Phoenix rising from the ashes of Pontiac.
And in the right corner the car with a name so diabolical it scared the shit out of Christian groups in the 70s
Let's get ready to Rumbleeeeeeee!
my stock 2021 f150 with the tt 3.5 would probably eat both these cars .
We can all smell your insecurity 🤡
And??
But not a 2021 built 400 with TT's
.............
And will still never be as cool as either car here. Get back to me when the 3.5 needs turbos, a water pump or timing gear cam phasers.
I have to agree with Lunch pack, I like older cars just for the fact that they had style, I guess they r like people in some ways....they don't have much style either & the cars b4 the 80s didn't all have a big computer running the thing, carburetor, motor,transmission,alternator, batter & a big ass gas tank!! Those day were fun, but its always fun to waste a lot of fuel l& make la lot of smog. Just not really a good thing today. We r living in New times now & we about to pay the price for being so God damn stupid.
They really screwed the 340 up with the smog crap an the government sticking their nose in the automobile business, Chrysler came out with the 360 that replaced the 340 ran one with the 360 an smoked him with my ,70 340.
👍🇨🇦
The definition of what’s allowed to be considered pure stock I’ll tell you right now these times of the stock vehicles doesn’t match up to the real deal back in the early 70s. A 14:00 wasn’t something all kuldip do. See where I’m going with this
Nobody sees where you are going with this because you don’t make sense. Try again.
@@jeremyrennersleftnut905 Have you spoken to your compatriot right nut lately, hear he's making a stink and causing you to be a little blue...
14.2 from a "stock" demon- not likely. Takes around one HP per 10 lbs to get to 14 flat. Oh and its not lbs ft, its ft lbs. on par with the metric system.
There's ALWAYS one of these comments in every vid, people please...READ THE ALLOWABLE MODS PER CLASS and these races will be more enjoyable to you.
@@edwinfeldman8231 TY!
quadrajet and 3:08 gears..come on
I've been 12.40s with a 3.23 gear and a Q-jet. If had has the stock 12" convertor that is his down fall. I picked up a 1/2 second by going to a stock convertor to a PTC unit in one of my cars with a low compression (8.1) Pontiac 350.
Another crummy mis match. 72 Dog Demon was the end of an era.
Pretty sure that you don’t understand drag racing if you think this is a mismatch
Firebird better then a slowpar mopar
Yep, Mopar Don't Go Far !

Expect the dislikes to be insane on this one. Pontiac guys cry on every video on this channel even when there's a win.

You care. Why else would you watch and comment?
I'M GOING TO LEAVE A DISLIKE BECAUSE I'M A PONTIAC FAN AND THEREFORE ACT LIKE IN A VERY IMMATURE MANNER. I CANNOT SEPARATE MY LOVE OF WATCHING THESE VIDEOS FROM MY DISLIKE OF SEEING A PONTIAC LOSE AND THEREFORE WILL DISLIKE THIS VIDEO ENDLESSLY.
