I’ve become addicted to these videos. A very healthy addiction!
My deceased brother had a 68 Barracuda with the 340 4 Barrel from the factory with the automatic transmission. We went 140mph in that car on the road.
I had a 1970 340 duster that would run a 12.76 in the quarter mile.
I know I've said this before but Nick is the greatest mentor on TH-cam and beyond.
That was simply amazing to watch. If people would only understand what they just witnessed - it's the same as a heart surgeon, but for old analog engines.
Love the accompanying music, Nick, very soothing to the soul in a world of chaos and confusion...
The small amount I send to patreon each month is EXTREMELY cheap "tuition" for what I learn! THANK YOU!
Wow, thank you Douglas! Much appreciated
You gotta love them 340, sat for alot of years and comes back to life! Not bad for a shakey first start.
Nice to see "old dirty" come back from slumber!
What a blessing it would be to have him as an uncle😢
Nick is probably the only engine guy I would trust working on my 455 engine, he is the besr
Thanks!
Hey Nick I am subscribed and I am glad I did because I never miss a show because I get a red bell telling me......Hey......Nick is on!!!!!!
it is that simple!!!!!! That is all subscribing does...it just helps you not miss a show.
I have no affiliation to Nick....other than being just a fan. Nick is a straight shooter and that is what I like and respect.
Along with with his in depth knowledge of cars and engines!!!!!
Awesome! Thank you.
Nick's just the best! Who else could take a dead chunk of cast iron, stick it on the dyno, do some cpr, and bring it back to life! Not just sorta running, but roaring like a lion. 300 hp, no new parts. Just the hands and mind of Dr. Panaritis.
Whenever opportunity arises... I spread the word about Nick's Garage. With my hardheaded buddies, I try to mention some of your more out of the ordinary episodes to pique their interest. Human nature will take it from there.
Yup, not parts changing. Just maximizing what you have. That's a mechanic!

MANY GUYS CAN IM ONE OF UM
I was awesome Nick I love bringing old engines back to life
Old story from the 70's. The original owner of my old 69 Charger R/T 440 ( I miss it so much 😥 ) had a friend that bought a brand new 70 Challenger 340 a few months later.
They used to drag race one another many times over. To his recall, it was always a very close race and could very well be called even. Both of cars were stock and both drivers were equally good.
The less torque / HP of the 340 was compensated by the Challenger lighter weight.
The Mopar 340 is a true legend on its own.
Taking one look at that carb and engine and thinking no way, but only Nick could pull a Lazarus and raise this engine from the grave.
My heart was pounding when she went 5000 rpm because I wasn't sure if the "little engine that could" would stay together. Respect for the commitment.😊
340's have forged crank, rods and I think pistons right from the factory, tough motors
5000RPM for a 340 ain't nothing and neither is 20000 miles on a rebuilt engine if it was taken care of. I've turned mine 8200 rpm at least that is what the memory tach recorded although I don't make a habit of it, it will do it, been running for 33 years, two trucks, two ram chargers and now in my off-road jeep. Don't remember who's channel it is here on youtube but someone claimed to have run one three seasons in a stock car a with stock crank, rods and rod bolts and turned it 8200 race after race with no failures and I have no problems believing him.
This small block mopar is just beginning its power band at 5k and will probably start floating out at 7.5-8k
Why wouldn't it? 340s are a high reving engine between 68 to 70/71
I'm glad Nick showed the process of hooking up an engine to the dyno. It's educational. Thanks, Nick. And my late father-in-law would have loved this channel. He was a Mopar guy himself. His favorite engines from Chrysler were the Slant 6, the 318, and the 383.
Very cool!
I agree with Nick's disdain of headers , I had a 69 Road Runner engine that I put in my 66 Coronet { excellent sleeper ! } , I put headers on , worst investment ever , hard on starters also , not to mention minimal perfromance gain over factory cast iron , mopar probably had the best factory exhaust manifolds of the big three , no need for headers on a street mopar .
Right on! I am with you
Just an uneducated guess under 4500rpm no advantage to performance for a street engine that idles around 700-850 with decent vacuum.
Every Chrysler owner hates headers because Chrysler front ends and frames are horrible to run headers on. Some of them are horrible for stock manifolds
@@davidstephenson7194 just installing headers on a big block B-body is an absolute pain. The steering shaft, the gearbox, and the starter all get in the way. To hell with trying to install a set on a street A-body. Better have a hammer and a grinder ready. I never use them on a street Mopar. Too much of a hassle for too little gain.
Totally disagree. Only a moron would run headers without using header tape to protect the starter and keep the engine bay cooler. If drag racers did what you do, Everybody would be running cast iron manifold's😂
Note the intake...it's a Torker 340. Thought by many to be worthless in the LA engine version.
RE: Headers - Nick isn't talking about one of the main reasons to use them on smaller lower-revving engines, they INCREASE TORQUE below the torque peak. So they do much more than make the exhaust flow with less restriction. That's a common misconception that has only been disproven in the last 15 years or so as more and more dynos have become available to the average gearhead. The long tubes help with scavenging which improves cylinder filling around their resonant frequencies.
I like the way nick says “carbater”reminds me of my grandpa Dominic when I hear him speak.
Thanks Nick that was fun to see a Start to finish of a DYNO setup!!!!!! And to see the 340 Roar!!!!!
The old motor is running and outside of that one expansion plug it's solid. That Carb gets rebuilt and you are golden.
I have built and ran many 340s. That motor is nearly identical to my highschool motor. Such a fine sound to hear. The small block Mopar is arguably the toughest motor ever built. 5000 RPM is below redline for that motor.
Nick, thanks for taking me back down memory lane. I was fortunate, my junior year in High School, to have parents who loaned me the money, which I paid back, to buy my dream car. 1971 Plymouth Duster 340 with the A-833 four-speed transmission. I couldn't wait to change the stock manifolds to Hooker Headers. This car was a stock street screamer.
Way back in high school, I drove 340 Duster. Hands down the quickest car In the area. So quick, in fact, that the blue oval and bow tie guys switched their allegiance!
I remember when a '71 White Challenger 340 auto showed up in our high-school parking lot. You heard before you saw it and that was idling in. I was the burnout king so at lunch time this Challenger fires up a d A CHICK wS driving . She tries to do a brake stand, but her atte pt failed. I ended up married to that girl and restored a blue/black 73 30some years later. Divorced now, but boy I miss that car. I out headers on it and 484" dual plane thermoquad 3.55 gears.
I will probably never have a need for this information, but you guys make such good videos and I watch them all! So much better than any of the crap on TV.
Funny thing. On my 70 440 GTX when I got it in 1980 I swapped out the stock manifolds. I installed a set of competition Hooker Headers. Pain to put on. They were pretty stout but I also added a 484 purple shaft cam. So it seemed to be a good combo. Fast forward to spring 2023 and a rebuilt 440. I took the headers off and bought original manifolds to replace them. $375.00 a manifold😂. Talk about full circle. I must be wiser for sure. But I still run headers on my 70 340 Challenger. But it is warmed up with cam and adjustable roller rockers. Cam is .498 lift. Thanks Nick. Really enjoy these videos.
So fun to see a Master Craftsmen show the stages of the dyno!!!!!!
Nick ain't haughty He's even happy to work on a crusty 340 Right now it's a bit ratty but Nick won't return looking this crappy Underneath all the crud there's a heart of gold and Nick's gotta test her to make sure she's no overworked dud A Mopar engine is never too old Nick's got all the equipment Nick's Garage has no equivalent They fix cars to pay the rent and on their clients cars they never vent It's all about respect and Nick's clients never have a shred of regret when they start enjoying what they get Nick can brighten his clients doom when he consigns their engine to his dyno room He'll Zing er up and give her some extra zoom A perfect illustration of Nick's header frustration on that leaky core plug situation Every Monday I can't wait to see What Nick's Garage wants to share with me Exemplary Thanks Nick Word George
Proof that the 340 is an excellent package. That intake manifold is not the best design anymore, but not as bad historically as people think! The Tarantula TM-5 is the higher RPM piece over the Torker, but the factory iron dual plane is hard to beat!! I'm glad the lifter noise cleared-up, I have a 1967 Polara station wagon with a 383 that sat for decades, and one lifter never recovered upon it's rebirth. I tried diluting the oil with ATF and Marvel Mystery oil, to no avail. I have a few new mismach single lifters, and I guess I'll stick one in someday. Thanks for the video, Nick! Great work as always!! RB
340 , imo was a little POWER HOUSE on the Streets 👍
Great engines.
Dana "60" Glass. Love any 340 Giant Killer you put on the dyno. Can't wait for more testing with your client
Thats a pretty strong little motor for being a crusty turd! Good find!
I’m a Ford guy primarily but I’ll tell you, my buddy’s 340 challenger was a blast. Love these little screamers…
yes those were the days, back about 40 years ago a freind in school had a 1970 "cuda" 4 speed engine was 0.030 over sized,915 cyl heads and some type of crane copy cam of the factory 458 lift cam, 3.55 gears. it had a 600 holley that was a truck application.vacum secondary. it had the stiff black spring in the secondaries. conviced my friend that the secondaries only opened 3/4 of the way. so i ended up putting the standard spring in the secondaries what a difference! it had pionts distributor point bounce like crazy. and had the best edelbrock intake that was recommended then an ld4bintake. it was like a little bulldozer.
This gentleman legend is legitimately the real deal! No one shares the knowledge he has accumulated over years of hard work, blood, sweat and tears like this man! He not only determines why an engine is stuck he shows you step by step with expert video and audio exactly what he finds! No one would take the time and video it to show how to actually install an engine on a dyno... completely!! from removing it from the customers stand to step by step bolting up to his dyno! No one in the business would share this kind of knowledge! I can't say enough about this legend! All I can say is ( God bless Nick Panaritis ) and hopefully he will continue for a long time!
From an appreciative fan( atic) WILLIAM IN BANDERA TEXAS USA
oh and by the way..his work and attention to detail is unparalleled in the business !
This is TOO much fun! Go Nick!!!!
Thanks Lee
@@NicksGarage We all know you guys probably can’t do this video series for the next twenty years…I sure appreciate today. Thank you for every minute you put it out there. Rock on Boys.
That may turn out to be a respectable 340. Nick seemed more positive towards the end of the video. Thanks for the video Nick. Fun one.
Thank you, George, for putting something pleasant as background music on this video. 😊😅
Always do our best to please. But with music it is tough to make everyone happy.
thats quite the engine stand the engine looked completely bolted to it that seems like a good safety thing when working by yourself plop it on then bolt it. should have 4 turning wheels to make it easier to get into tight space like the dyno room . interesting concept
And built to last.
maybe its also built to run an engine on the stand for a few minutes. but yes it would be a good product for longevity. Have a good Week@@NicksGarage
Headers on an engine are similar to big speakers to a home stereo: bigger ain't necessarily better...but it sure looks sexier when you see a bass bin instead of bookshelf types. Factory headers are in fact better because only factory made products are tested in congruence, where every part of the car has to be torture-tested, right down to the am radio. So, manifolds are the wife, and headers...the girlfriend.
Those are some groovy tunes playing while Nick is installing the 340 on the Dyno George! Looking forward to the rest of the video!
Absolutely love the mopar 340. Very good engine. It was better than the 360.
It sure is!
in stock form , any 318 340 or 360 can be made better they are all just about the same , all can be the base for a great build
I was wondering how Nick mounted an engine on the dyno. Thanks for showing the process.
As it sits a 300 HP 340 is a respectable small block output for a cruiser..the base 350 cubic inch corvettes from 1969 to 74' , then the L82 350's made 300 HP at the crank & they were lively fun drivers.. But we'll see more power from this 340 I bet after Nick tunes her a bit . 👏
I love when it is Dyno time with Nick!!!!!!
I've been playing with cars for many years. And still learning to this day. I'm a GM guy but really like learning about the Mopars. Nick you taught me quite a bit. Keep up the great work that you and the shop do.
Hi Nick it's been a long time since I chatted with you I would have to say my 1970 340 Duster Factory pistol grip 4-speed was probably the fastest stock production car ever made. The only thing that I ever did to it was put a set of 391 in the rear end and that was all she needed. Anyway Nick I hope everything is going well with you I just wanted to say hello
Nick is a Diehard Mad Mopar Scientist, God Bless you Greek Canook 🍁🌿Thank You for the Mentorship Big Love MOOSE & JILLY from Michigan ✋🇺🇸🏁
Nick and George, you two keep capturing the real essence of old fashioned back to basics engine diagnosis… compression, air, fuel and spark! Align the timing, seal the leaks, and let it rip. Impressive HP/Torque for an old 340. Cool! 👍😃
IT’S ALIVE! Made me chuckle recalling the movie “Young Frankenstein”…
Heck, even I can be a little “grumpy” upon waking after a long nap 😴
The secondary air door didn’t fully open until just before the end of the pull.
I want to take a moment to compliment your video editor it is a amazing job on every aspect from sound to visual.
Wow, thank you!
Yes indeed Nick , headers .. I had to put headers on everything I had even a 350 in a 68 P40 GMC stepvan service truck . One application I installed headers on was my 98 Dodge ram 1500 magnum . A great engine with alot of power stock . But the engine lost torque and it was notable .
The upside is the truck gained substantial mileage . Headers provide efficiency and CAN improve mileage . Now this statement is solely based on the header application and is not a blanket endorsement of mileage gain. In my 50 years of auto repair and performance vehical headers were part of my builds . I am in complete agreement however on headers leaking , scraping the ground , and all the burnt plug wires or melted plug boots and related starter problems all the time from header heat soak . In the posative for headers they really provide a performance boost . Not necessarily only at higher RPM but can benefit all around . The small block Chevrolet
Is a prime example where headers really trounce an exhaust manifold. Negatives I've stated and like Nick I've come to hate the Hassell and problems related to them . In the repair shop world though , it does become a hinderence to deal with headers and not worth fooling with them . There are some makes that need a header where the stock exhaust manifold is a log style disaster!!
Scott in so ca
Thank you Scott.
Love how you " stick it on the dyno " !!!!!!!!! 😂😂😂❤❤❤❤❤
Dr. Nick , I had a 340 in my LAPD that I got from the 2nd owner, and it ran like a clock, thanks for showing us how you put a engine on the dyno, it was fun, cheers.
Great to hear!
I just love the sound of a 340! There just seems to be something special about that configuration. Almost as if they are a "square" engine.
4.04" X 3.31"
bord out 318.
I had a 1968 satellite with a 318 back in the day and wanted to put headers on and I did but had to disconnect the steering linkage to get them in
No fun.
I’ve been waiting for this video for decades now!
Here it is!
The one thing I found about headers as opposed to factory exhaust manifold... the after market headers always lead to cleaner spark plugs because the headers allow for better evacuation of the burnt gases and hence less built up of carbon.
This means less chance of hot sports and pinging....
I have never seen an old skool engine that is not better off with headers over the factory exhausts manifold.
It might not give you any extra noticeable power, but your engine will thank you if you fit after market headers.
The best are the Tri Y's... the 4 into 1 are only good for drag racing and WOT.
This video was a welcome change at 1:13, Sorry George, lots to edit but the format of showing the amount of effort that goes into a “Let’s see what it can do on the dyno” is well worth it and something we all needed to see. Nick makes it look easy but there’s lots to know about making it happen. Oh and maybe I’ve missed it in the past but, great idea to split screen Nick and the Dyno monitor so we can see the parameters as Nick is revving and analyzing the machine. Damn Headers..
Keep them coming 👍 👍
It's always a pleasure to watch you work, you are the Master of horsepower. I learn something every time I watch.
My 71 monte carlo had headers that would roast the starter.wished it hadmanifolds
I totally agree with Mr. Nick I bought a Chevy truck with headers and you have to pull them out of the way to change spark plugs. Couldn't agree more right on Nick!
Right on.
I remember installing headers on my V8 Vega. That was special.
Mopar's true little sleeper motor.
Interesting that you have the crane in there. At JBA we had three dyno stands that were mobile, we did that swap in the machine shop. Then wheeled it over to hook it up to the dyno jet. Both ways work.
I have fenderwell headers on my 1963 Savoy... easy peasy. Easy spark plug access, motor mount, starter access no problem.
That old 340 sounded like it was just loping along. I’m curious to see what she’ll produce in the next few days
For an older engine it did good! The owner should be happy. Course, if Nick rebuilt it and "Massaged" it a little, who knows what it will do.
Good video Nick. Takes a lot of "detailed" work to get the engine set upped on the dyno.
Thank you. You are just the best engine guy there is .Keep on making videos about what you're up to
Thanks, will do!
Thanks Nick....treat to see a older rebuild on the dyno brought back to a running state as well as a Thremoquad being used with it...great job and good content.
Glad you enjoyed it.
That's awesome to see a stored motor come to life. Sounded bad to start but not so bad at the end . Great Job Nick
good numbers for an unknown spec 340 . Mopar underrated their engines .
I've been racing/running 340's since 1971. I'm older than Nick! As nasty as that old carb is 300Hp at 4,900 rpm is surprising. I would love to see where it peaks out rpm wise. Can't wait for the next video! Those Torker intake manifolds were lousy too! Back in 1973 we tested one vs a LD340 on our Super Stock 340 Duster and it was a solid tenth slower than the LD340 and that was swapped at the racetrack. The stock highrise was probably better too.
Right on!
Love the 340 ! 😊Awsome Monday
Happy name day for Wednesday. Steve from Adelaide Australia tuned in yet again
Thanks Steve. Giassou
hi Dr. Nick, hi George, glad 2 be here.
Welcome back Eric
Cheap headers are always a mistake. Quality coated headers with 3/8" flanges, copper gaskets and flex joints just aft of the collectors are pretty much a bolt 'em on and forget it deal. The flex joints take all the strain off the headers, hence they don't crack and gaskets last forever. Previous set I had I didn't have to put a wrench on them for 6 years. Current set is two years and counting. I did cut the #6 tube out and reroute it to keep it from frying plug wires and putting heat in the firewall. Oil filter is a breeze and the starter has plenty of room. 410" roller block LA btw.
Love the Dyno Room !!! Nick can do that tuning and fixing on those Mopars with his eyes closed !!!! Those ol 340 engine ,brings back some great memories of a good Friend who had a 340 Duster that we use to cruise around and race some . That sure brings back some really good memories this Monday . Love it ,Nick and George!!!!
Love it. Had several 340 cars in my younger years. Bought my first car at 15. It was a 73 challenger rallye with a 340. Had 3.91 gear sure-grip in it. Stock intake with spacer plate and Carter AFB carb. Was a very quick car and easy to get sideways. I sure miss those days 😢
Easy to get sideways is right. My buddy Ed Lester, in college at Eastern Kentucky University bought a new 340 that came with 3 deuces from the factory. He was going down a narrow street at the university, floored it, wet sideways, and took out about 4 to 5 cars on each side of the street.
Evenin Mr George an Mr Nick!! Have a Great week!!
Thanks, you too!
I agree with you Nick ,💯 percent. In the late nineties I had a 79 monte-carlo with a medium built 350. Friends pursuaded me to get headers, I knew it was going to be headaches.Changed gaskets all the time, hard to work on car. I ended up putting the manifolds back on and had a lot less trouble. I couldn't tell a difference in performance either and like you said it was a street cruiser. By the way those headers look really nice on that 340. Stay safe Nick and blessings.
Sounded pretty good once it ran for a bit. ❤
Hello Nick, love your channel, little older than you, been thrashing MOPARS a long time. Love the 340, highly underrated and appreciated. I personally know of many surprised by the little A engine. My favorite being the 69 Dart.
Keep up the great footage and God speed.
Thanks 👍
I love nick and scotty ! They are excellent !
Thanks
Hi Nick, I loved this episode. The step by step process of what it takes to get an engine ready for dyno testing was much appreciated...!!!
Glad you liked it.
Both great motors 340 or 360 👍🏻💯🇦🇺⛽️
Nick your simply the very best engine builder of all makes the knowledge you possess is just mind boggling. I know quite a bit about engines like you nick i spent my entire lifetime messing with cars but let me tell you every time watch you do your magic i learn something new. Thank you sir
We need a compilation of all the times nick says he hates headers 😂
I was thinking the same thing. Everytime sometime mentions headers now I think of Nick.
Wonder what my .30 J headed Thermoqaud equipped mystery cam 273 out of my 65 Dart GT would make on the dyno.Runs perfect I would guess around 300.
The dyno tells all
If Nick can get hold of a 273 4bbl, I bet he can get 400hp out of it on headers and a Edelbrock AVS 650cfm, solid cam and lifters. 1.6 steel rocker arms.
We want to see the rest of this story, maybe with a new carb. 👍
I really think that many people don't appreciate how much work is involved in mounting an engine in a dyno. Running at full rpm, everything involved in the installation has to be double checked. It is actually the same amount of work as installing it in the car.
Safety of the men, engine, and equipment has to be to be carefully considered.
Same amount of work? Yes and no. Yes, the list of stuff needed to be done is pretty much the same to install the engine on the dyno vs in the car. At the same time, because the dyno isn't a car with a body, frame, suspension, and steering, accomplishing each of those steps is easier than doing them in a car.
AND A DYNO YOU CAN DO ALL THE TUNNING RIGHT THERE MY DYNO IS DRIVING CAR DOWN THE ROAD AND RETUNE AND DOWN THE ROAD OVER AND OVER UNTILL I GET IT EXACTLY HOW I WANT IT TO RUN, BEING A MECHANIC NEVER WAS OR IS EASY YOU HAVE TO LOVE WHAT YOU DO OR YOU WILL NOT LAST AND THAT MY FRIEND IS A FACT AND THE DYNO ISNT TELLING YOU REAR WHEEL HORSE POWER , NOT A CHASSIS DYNO@@kart70
It actually didn’t sound half bad once the lifter tick went away. I’d be curious to see what just a carb swap would do for it 👍
Yes, the 340's were some great engines..Easily modified to make more power..This engine and the 327's were some of my favs..I hope they show it's full potential with a fresh carb if they run it again..
yeah dial it in
You are always true to your word Nick. Thanks to you and the crew. I hope you didnt get as much snow as Montreal. Cheers
Always fun to see them wake up. Nice video. Thank you.
Dr. and Master Mechanic Nick Panaritis is a scholar of engines. Every time class is in session, I become more educated. George, love the camera and editing angles. Both of you pay attention to detail. Love it!
Awesome show very informative was always interested in what is in between engine and the Dyno a good run for a engine was just sitting around keep them coming and see you Friday
Another good one Nick ... I just want to give a shout out to the great camera work, giving us the feel like we are with you in the Dyno room along for the ride !
I appreciate that!
You’re absolutely right, unless you’re horsepower hunting and trying to get every last bit out of a motor, headers are just not worth it most of the time. Even on the old square body trucks that look like there’s tons of room everywhere under the hood, there really isn’t where you gotta try to fit headers.
Such wieners, headers aren't that big of a problem to fit and the gains in hp and torque not to mention potential increase in gas mileage and a cooler running engine makes them damn well worth the effort.
