Here's a great way to spend a little while.. In the dyno room with Nick and a classic MOPAR mill.
Nick: try to get down to DC sometime and visit the National Air and Space Museum on the Mall and out at Dulles Airport. You can also tour the restoration shop in Silver Spring, MD. I mention this because whenever the restorers need to make a part, like a strut perhaps, they engrave it as a reproduction so the next guy won’t think it’s original. You should mark your shift rod with “Nick’s Garage 2020”.
My Mopar roots run deep. The first car I ever drove was my mother’s 1952 Dodge four door with the semi-automatic transmission. I got my license at 16 in 1961 in the family 1957 Chrysler New Yorker four door hardtop. I took the only behind the wheel driving test in my life in downtown Baltimore in mid-day traffic. The inspector had me parallel park that monster on the street too. “Just pull in there, Kid.” I think I impressed him, but with the fins out back with a radio antenna on each one, it was a snap. 392 first generation Hemi with 325 gross BHP of course. Later my older sister bought my grandparent’s 1952 Dodge business coupe. That one had a manual transmission with fluid drive not a torque converter. You could put it in third gear, let off the clutch, and the car would slowly accelerate with the engine at idle.
Finally, I have a friend here in Annapolis who has an office in an industrial park. One side office, the other garage. I didn’t know about any of this when I first visited him. When I was about to leave he said “Look at this” and opened the door to the shop area. In there he had one of each Barracuda body style, a 1971 Duster drag car, and a Jensen. He’s getting on in years, but he still has the Jensen and one of the Barracudas.
Jenson"s are cool. Nothing with a 440 looked so...very British?
Dang it, I was there (D.C.) about 6 months ago. I wish I had known about that museum then. I’d spend a week in it.
Oh well, next time.
We were all Mopars till dad saw a 351c 71' mach1. But on the lot next to the mach 1 was a 70' 340 six pack Challenger T/A in drab green with the ram air hood. It was a hard decision but we got the mach 1. We are talking 1977. I had a buddy that had a 71' 340 Demon 👿 that ran 11.43 quarters consistently. I have alot of Respect for those 340s'. Thanks Nick for posting about 340.👍
I love watching how meticulous you are between tests, making sure everything is running optimally.
Nobody:
Everybody scared out there from the virus
Nick: testing a 340 like it's a normal day
We need this now.
@@NicksGarage good engine rebuild and its strong for a small block 340👍

@Nick's Garage
You’re damm right! We need more videos like these, now more than ever. Nick is not letting this virus get him down. Gear heads around the world await your videos Nick. God bless you and keep you.
@@NicksGarage Nick, I wish your customer could have been there to give the OK to take it up to 6000 RPM. Perhaps 350 hp is lurking up there.
I had 1970 Cuda with a 340 Six Pack that put out 310 hp at 5,000 rpm so I guess we will see shortly. I loved that car. My ex totaled it. I bought the salvage rights to it but I never did anything with it so I sold it. My heart was broken...
Damn dude that sucks, I had a 71 super bee that unfortunately got totaled when I was racing it at the track one night
I had 69 Road Runner 383 -335 HP. Loved it , restored it once and let it go. Biggest mistake I ever made!
I figured the mildly hyper 6 pack 340 with headers would make more than the basic 10:1 300 HP 327"... like 325 HP... surprised it did it with iron exhaust manifolds... thought you'd rev it to 6,000 RPMs, though... 340 was Chrysler's '327'... both liked to rev... 327's were actually a tad over rated in HP, but close to their rating...
I drove a friends's 1970 Barracuda Trans-Am once. It was a 6-pack 340 that may have been hotter than other versions. Was very picky on how you drove it, and required different spark plugs for street driving vs. fast/race driving. I was used to big block Mopar engines, but was very impressed with this one!
@@BuzzLOLOL that post is idiotic lol
Nick is probably the best boss you could ever have. Wish my boss was as cool.
I've always been a GM guy through-and-through...but who in their right state of mind couldn't love a 340 Six Pack? Great attention-to-detail, Nick! A hard-running piece of art!
Badger. Thank you.
Drivin them..acually not the screamer one would think. ..acually aunties 71 nova 4 door eith a 300hp 350 could out dash the 6 pac challenger . Overrated.but awsome
@@The56strat, Personally, my experience is that no one made a small block as good as the SBC. However, would have to give big kudos to Ford for the Cleveland, but that's about it!
@@The56strat ah yes, a 3400lb car vs a 4000lb car...what a great comparison. now go race a 70 dart swinger 340.
Larry Niles Total fact actually. I personally own a 67 Malibu factory 327 car as well as a 63 Polara with a 322” LA SB. Both cars have dual plane high rises, .480 cam in the 327, .465-.472 cam in the Mopar. Both cars have headers, both are Automatics with stall converters. The Malibu has 3.31 posi, the Mopar has 3.23’s. I’ve raced the 2 many times and my Dodge has never once pulled away from my Chevelle. I built both cars, with similar combinations and outcome is what it is.
thanks Nick we really need something good to take our mind off of whats going on! ya'll stay safe and GOD BLESS
A magician at work and incredible knowledge at what you do Nick, keep up the work . These moments are tough for all but what you and George do brings us some happiness every Monday Morning................Stay Safe
Thanks Johnny. Stay safe.
Love your videos, and really enjoy each and every one of them. Owned a72 Dodge Demon 340 black on black that I bought brand new and was a great car. It was the only Mopar I ever owned, otherwise was always a GM guy,although a lot of guys I ran around with back in the day were Mopar guys. A couple of them owned AAR Cudas,as well as Ridge Runners (lol) and if I could afford to, I'd probably buy one today, just couldn't say which one because there are so many that I like. Take care and be safe to you and your family and friends as well. 😎
Stay safe Nick! Thanks for giving us something to break the boredom.
Thanks for being here, Carl.
It's different seeing Nick without the usual crowd in the dyno room. Weird times these days.
I know Nick's a social guy and loves people but I bet he can concentrate more on the engines now without all the distractions haha.....
I pray this quarantine is over soon and for everyone’s health and safety. Getting back to normal is what it’s all about guys. Please, be smart, don’t put yourself in danger of this disease.
Thank for keeping the videos coming, gets my mind distracted from what's going on at this time for a few minutes, completely focused on what you're doing. Can't wait to see the keeper come back to life for a test drive. God bless us all.
Thanks Dwayne. We appreciate you taking the time to be here.
Mopar 340: most underrated best small block ever made
Great engine. Might I add, all the Mopar small blocks are wonderful engines.
chris younts light car is key. Completely different experience in A-body compared to a later e body or b body
Wait a minute... 340 six pak stock.. 320 HP ? Chev. 327 4 barrel 350+ HP.......
sbc 327 made 375hp in the Corvette. And Jenkins was making upwards of 500hp with stock shortblock and stock heads in the 60s. 340 is a good engine but doesn't even stack up with the 327
Hal 1000 Underrated by who??.
I would check the oil pressure relief spring. My 302 Mercury was blowing oil filters off when it jammed...
Nice! It's acting like it's over corbed with the 6 pack carburetors supplying more of air and fuel than it can handle. Maybe if the timing was advanced a bit more to compensate? Keep the videos coming!
Nice work👍 I've owned 3 TAs all at the same time for years for which 2 of them are in museums now, pure stock all the way up to 500 HP. Not once did I ever have to mess with the carburetors. It is important to understand how to set them up properly from start.
I'll put a nickel on 325 hp and thanks again Nick!
I really like the videos of these rarer classic muscle car engines. I prefer them in stock configuration just like they came off the factory line. It's like watching a living history of those years. I would be interested in seeing dyno runs of the high compression small blocks like the Chevy 327 L79 had solid came, and 11:1 compression. I know Ford had some of those also.
Love ur videos and ur humor. Stay safe.....keep it up...
I've had two of the 340 six pack engines and one 440 six pack engine. Yes in the factory cars! My honest guess for the 340 + 6 was around 330s... Not far off. Being isolated out here in rural Southern Michigan , it's great to see a video for the 340 + 6. :-) thanks Nick and crew :-)
@Jd Thorpe My 440 Fury stops crazy good for how heavy it is. The C bodies did have some of the largest brakes Mopar used at the time though so it might be a little different.
👍👍👍👍👍 south of I 69/94 interchange .
@@beckywatt5048 I'm bout 10 miles so of 94 & east of 69
I'm amazed the h.p. numbers are so low! The 340 4bbl engine y'all did for the 70 'Cuda i believe, was around 1 horse per cubic inch, I was expecting 360 to 375 horse from the 6 pack atleast! But y'all are only around 300 teens barely breaking 320,hmm. I'm very surprised it's not much higher! 326 h.p. 347 torque, i was waaay off compared to the other 340! This engine wasn't rumbling like the 4bbl at all either.maybe it's just not a "beastly block " from birth. What i mean by that is, some engines,regardless of all things from the factory being equal,seem to just have more balls and power than the one built before it and the same exact one built behind it! It's just some crazy anomaly that happens. My college buddy worked in Detroit for Chevrolet /GM all through the late 60's and 70s until they shut the plant down, after he survived his combat tour in Vietnam. He said for some strange reason or another, that although the engines were coming off the assembly line assembled basically to the same exact parts and specs,he noticed that some just had more "juice" than others. I'm wondering if that's the case with this build and block. Thanks again guys! great stuff, soundtrack and all, as always!
@Pauly Gambino that'll do it! As much as the Chevy 350 gets for hype, and no doubt it is a good engine, i've always loved the 340.
I love the 340. I had one, although it was the lower compression 1973 version.
Glad The Keeper found a home.
6200 would have given 340 hp, 1 hp per cube. Headers would give you 360 hp. The Chevy and Ford SB killer. Lived it as a Ford smuck.
Thanks for being around with videos during this time Nick! Your quality hasn’t even dropped in the slightest!
About what I expected. Thec340 has the bore and stroke plus long rods to be competitive withe the 327 Andc350 Vhevd or the 352 Clevelsnd.BUT it doesn't have the heads or cam to flow enough to really usevthrv6 Pak.i have a 70 Challenger TA. It is a relatively heavy car
20 years ago I pulled the engine .
Set it n a corner.
Built a 360 engine. Used a non CNC d set of Edelbrock heads and a relatively hot hydraulic flat tappet csm.Edelbrock Performer RPM intake two step hesders.This combo resulted in 424 hp and 440 ft lbs of torque.
Which puts it squarely in the ball park with my Rochester injected 350 Cev engine in my 65 Vette.which put out 420 hp and 42l ft lbs of torque.
And the 351 Cleveland in my Pantera 426 hp and 422 ft bs of torque
ft bs of torque.
For a very light Mopar say a Demon thev340 would be a nice engine with enough head and CA. But as delivered from t he factory in my opinion a sharp rumning 327 Chev running the factory solidlifter cam and in a 66 Chev II is going to be faster.
For a heavier street car I think the 360 is the way to go because it will ae around 80 ft lbs nore
torque than the 340.
In fact it makes the same torquecas a stock 383.
If I recall correctly Nicole builtvac360 and got really good results
craziest engine ever put in a car! 340s were insanely fast for their displacement.
yup back the day we used to race they used to make header mufflers andbwe used to put a screen in air cleaner and put dry ice to drop intake temp pulled low 11s over and over and few 10s
A bit weak thought they could go to 6500 no problem and still make power...327 just come alive at 5000 rpm just saying!
@@rjmzz430 my 327-350 smoked 340's
it could hold its own,see 1970 scca trans am series for an idea of what detroit could do,everyone had a hot smallblock
@@johnthonig8832 I doubt it unless yours was modified!
The oil pressure was extremely high on the 340 six pack. I'm not sure if was safe to run the engine like that. What did you discover why the oil pressure was maxed out?
Good power but it's only half the story, the 6pack smooth cruise motor.
you never cease to amaze
Damn the oil pressure is good over 100 PSI at 5300 RPM LOL!!
Well spotted.
One 850 Holley would deliver more h.p.
3-2 barrels were and are a joke.
SMH.
It's not often you find a guy that goes the distance to make sure it's absolutely perfect. As a auto tech in Michigan I appreciate everything nick does. Keep up the perfect work thanks for sharing
Didn't cheat..... my guess....305hp at flywheel.
I'm pretty old school but that seams to still have a carb ballance issue. You can get the air fuel right on those but still have a carb ballance issue. If the 2 outside carbs are running rich and the center carb is running lean you would still get the O2 sensor reading correct. I think there is still some left in that six pack.. Just my observation for what it's worth.
351 boss or 68 340 or 340 -6? Which one has more ftlbs and hp
Thanks to Nick and George the camera man for keeping us all entertained while stuck at home . The package sound effects crack me up , great editing job George. Look forward to your next video.
Makes me want to get my XS29L 68 Charger out of my garage and get it going again.i haven't drivin it since 2012 owned it since 2003. My Dad bought it in the mid 80s for 2500$ all original.
Ive had 5 68's over the years. Never paid more than $500... Sadly i think i shoulda kept one, those days are over...😕😕
I was guessing 325 because thats what my 340 six pac had with a racer brown solid lifter cam.
I see this video is a few months old but it's new to me. I say 350 HP @ 5500 RPM factory low balled all HP back then for insurance reasons.
My favorite small block mopar. 335 hp guessing
a good call.
I watched all three times. The pulls on the Dyno! He made adjustments. The front two barrell on the right side was not with the program till the end. It was not squirting like the back carb. This engine runs on the middle carb till you kick the other two in. I was hoping for 360 hp with matching torque. These little T.A. motors can really get up there. Great job Nick. We need more video's from you. We are stuck at home! Try a 3.5 24 valve H.O motor on your Dyno. Yes its fuel injected. But doing a modern engine with headers and a laptop tune. Could take it from 250 hp and 255 torque to well over 300 hp and 290 torque. Its still a Chrysler motor. Come on Nick I have one in my Concorde LXI limited. Its the same motor as the 300m. Shawn
Secondary carbs are vacuum operated.
I am slightly surprised that the motor put out that much power in its almost bone-stock tune. No wonder the 340's ran so well back in the day.
No accessories. Waterpump, alternator, pollution thermactor pump, ac... all that stuff reduces power.
@@johnb7430 Isn't that the way all american makers rated their engines back then, for Gross B.H.P.? I thought "net" horsepower would be what you are describing. During the muscle car era, it was not unusual for manufacturers to fib slightly about power, but in most cases, engines were overrated, not underrated. To exceed the rated number by 36 ponies was unusual, unless the engine was a NASCAR big block.
A well worn 340 6 pak will. In good time give 300 ponies.
I just pulled one of those transmissions out of a IR carbed 1967 Shelby GT350 I'm working on, interesting
Hi Nick. Are 340 3x2 exhaust manifolds unique to the six pack engines or are they the same as 340 4bbl? Thanks.
Montreal. Exactly the same as the 4 BBL.
I can’t get enough of that overhead view of the outer carbs opening! I was surprised how well they metered themselves and open nice and smooth as rpm increased.
Is a dual quad better than a 6 pack versus a 4 bbl carb? Do they really give more power just because there are more carbs or do they simply drink more fuel?
Dyno Room = Perfect "Social Distancing" spot.
Nick's Kid Dyno-Mite ! love 340's
I had a T/A Challenger and of course wish I had hung on to it. I would love to see you do a comparison between a stk Six Pack manifold and one that has been extrude honed. Reason being I have seen dyno result that showed the Six Pack wasn't really as good as it could have been when comparing to single 4 and duel 4 manifolds.
Hi Nick, I've been watching you on you tube every day. You have some great content. I enjoy
watching and guessing the H.P. on your builds. Been a car guy for ever, had a 69-GTO W/400
small block, had a 72- W30 Hurst Olds w/ 455 Ram Air & a 4 speed M-22 Muncie. Put a set
of headers & a set of cams. That sure made the car a handful, wife did not like, but I did. Thanks
for the great past time. Be careful & be safe.
When I was a young teenager, my sister's boyfriend took me for a spin in his new 340 Demon.
Scary fast.
Yes - me too in High School - those cars were VERY light in weight - so hp to weight ratio was very favorable
@@LoveThatRod rust bucket
Extra spark down there
Hi, Nick. Great video. I love the multicultural nostalgia. Your "missing link" reference was funny. You mentioned the Pantera, let's not forget about Tim Horton,
R.I.P. ....The 340 six pack is one of my favorite Mopars, nice weld on that bell housing. Hope the input shaft on your dyno was not damaged due to vibration of misaligned flywheel on the old hemi. Glad "The Keeper" found a good home. Love mail time, cool stickers.
Stay Safe. 🤓
I would have guessed a little higher HP.. But respectable for a stock build.
Jordan Matte : I guessed 340 @ 5500rpm and expected 380 lb-ft at 3800. Customer engine, missing a few extrs runs fettling the air fuel. The carb system is very special and I see the love of the Master on setting the mixtures. 326 hp gross is what it ran on the day. Exceptionally well organised wedge engine with cast iron headers and its everything a 351 C 4v is with less cam, less cubes, simpler heads. Mopar engineering in these LA engines was exceptional. :-)
"The missing link." Priceless!
From the factory, these 6 pack 340’s can make 350 horsepower at 6,000 RPM. They’re capable of revving up to 7,000 RPM straight from the factory
Pretty stong for a small block
I did not know that Edelbrock made the 6 Pack intake manifold back in 1970-1971.
Me neither
I love the 340 small block Mopar engine. Many years ago I drove a neighbors 69 Dart with a 340, 4 barrel, and 4 speed and I loved the way that car ran. Thank you for another great video Nick, I hope and pray everyone at Indy Auto and family and friends stay safe and sound during these scary times.
104 psi of oil pressure, wow. That should be dropped, I believe you would get more hp's
Oil filter ballooning time!
The filter will take like 400 before it deforms or “balloons”
good morning Nick man i love the sound of smaller C I engines, keep safe thanks
Morning!
Not too surprising, chrysler was a good one for under rating their HP anyway
Factories back in the 60's and 70's always sown played the amount of home a engine made for insurance purpose
Around 70_71 the government required manufacturers to state the NET horsepower.
You know which engine I've really been hoping to see on a dyno? One of the old school 302 DZ GM engines. I'd like to see someone do a high compression high RPM build with a 6 speed manual in a 67-69 Camaro. Besides the 572 and 502 GM engines, it's one of my favorites, along with the 302 Boss Mustang Ford engine. That being said, I'll always be die hard Chrysler. It'll NEVER get much better than the 426 Hemi...the Elephant.
Nick, that was really cute about the Greek rod!!! I have a question about the 340 six pack. I noticed when the throttles opened on the secondary carbs, that's when the hesitation occurred. Now why doesn't the secondaries have accelerator pumps??? Could this problem occur in the field or just on the dyno???!!!
Pretty sure that the outboard carbs are supposed to be activated by vacuum signal from the venturi of the center carb (like a 4-bbl vacuum secondary carb). So by mechanically forcing them open, they’re probably opening a little early so it gets the bog when the engine goes lean for a moment... no effect on the peak power reading, but the drivability will actually be better in the car.
@@karlkoenigstein4138 I appreciate your response. To me this is why most people probably complain about the driveability of the six pack, since what you've explained seems to be the issue at hand. Yes, I've driven dual carburetor engines, but I never noticed any bogging when full throttle was applied. These were two 2 bbl carbs with a primary and vacuum operated secondary throttle butterflies.
"Uncle Tony's Garage" has a video about tuning the Mopar six pack he explains the process clearly.
Cheers guys, good health.
Nick, you got a lot of co-co. Don't eat to much you might run out of TOILET PAPER.....
Nick I wish you well bud through these crazy times on our planet . I’ve been watching your channel for a bit over a year . I have enjoyed every single one my friend . I hope to have an Opportunity to see your shop in person one day. Keep up the excellent videos , take care !
Given that the 340 was created to offer 383-like power (330 HP) in a 318-sized package to be a better fit in the A-bodies, this came out close to what I'd have guessed. I've heard the four-barrel 340 with the 4-speed cam would dyno at about 320, so this result for the six-pak seems about right.
Maybe you can give light on the 340? The rumor was when I was a teen that the 340 was a bored out hopped up 318. Is this true? I know I 1/4 mile several Demons with a 1970 Road Runner I had. The 340 was not to be taken lightly.
The 340 was based on the LA 318 but was designed to withstand high RPM operation in drag and/or road racing. In a light vehicle such as the Mopar A body it gave many big block cars a run for their money.
The Coal Dragon Forge smaller (identical) mains on 318/340. 360 has bigger main bearing. Makes 360 crank kinda pain in butt to put in 340. 318 crank will fit but takes too much to balance. Oh god , I could go off on tangents now lol
In 1965 Chevy put the new 350 hp 327 in the Chevelle as 325 hp. In 1966 Chevy put it in the Chevy II in 325 hp form without the Corvette windage tray. In response, Mopar designed a new 331 engine for 1967 with a hydraulic cam. It's performance was embarrassing compared to the 327 and even the solid lifter 273, so Mopar did not release it. The 1967 and early 1968 318 LA engine blocks were thick enough to be bored to 4.00 inches for the 331. In the 1968 redesign of the 331 to 340, the intake ports were made the size of the 327 ports and so were the valves. The bore was bored to the Mopar maximum of 4.04", from 4.00" for 340 cubic inches. The original 340 camshafts, especially the manual transmission 1968 cam, were designed for 6500 RPM redline. Since cast pistons were used to keep costs ddown, the valve springs were weakened to protect the cast pistons, for a redline of 6000 RPM and usually wouldn't run that fast.The manual transmission cam was 22 degrees larger than the automatic cam, but with the valve springs it was difficult to take advantage of the larger cam. The cam was designed to specifically beat the Chevy 327, which was also a manual transmission only hydraulic cam.
@The Great Cornholio You can't bore a 318 out to be a 340. Also the 318's mostly used cast cranks where the 340s were forged. So were the rods and the 10.5:1 pistons, heads were 18 degree, 2.02, 1.60. Big dual plane intake. Saying a 318 is the same as 340 is like saying a 4.8L truck engine is the same as an LS1.
The Coal Dragon Forge you should get your facts straight. The 318 and 340 main journals are 2.4995’ TO 2.5005 the rods are the same length to 6.123’ but the 318 weight is 726 grams and the 340 is 758 grams. The cranks are interchangeable and are both forged. 360s are small blocks but have very little in common with the 318-340s. There’s some parts that are but as far as the rotating assembly goes not much.
Nick the gas stations nowadays are gas/food marts, least that’s what they call them in Ky. & Ohio. Just wanted to let you know that buddy! You guys stay safe and well up there and take care! Doug
I was a performance engine dyno operator at the Chrysler Tech Center from 1966 to 2007 and actually tested the 340 6 Pack along with all the other performance engines we developed. Back then we tested from 1200 rpm to 5600 rpm all 340 engines and we took readings every 400 rpm. We spent about 3 minutes at each speed taking all our readings manually by hand including F/A at every cylinder at every test point. Your numbers are pretty close to what we made back then. We ran the water pump off the the crank pulley. And by the way we were in the room with the engine running the tests. We put a wire cage around the engine to catch any parts if something broke. After 1970 the government set up safety standards to have the operators in separate room like they do now.
Very interesting. Thank you, Ed.
I was working at a Chrysler Plymouth Imperial dealer in 1970. The 340 six pack cars were very fun. One of the things I remember Was we had a AAR Cuda. with the 340 6 pack and a Cuda with a 440 six pack. both had the same rear axle ratio, tire size and torqueflight transmission. The 340 car would hook up and come out of the hole very good. The 440 car had a traction problem. It was tricky to launch. That 340 would rev to 6000 before it shifted the 440 shifted at 5500. 2 out of 3 times the 340 would beat the 440 mainly because the 440 would smoke the tires and the 340 just hooked up and went. If we could get a good launch the 440 was definitely faster and would always be catching the 340 at the top end even with a poor launch. They had to replace the rear tires on the 440 before it was sold. We were told that Chrysler underrated the 340 horsepower and NHRA must have thought the same thing because they changed the class that they ran in to a higher horsepower class. Great Memories!

yes, he does have a sinister laugh,lol.
I figure maybe 330 hp? When you don't have a radiator fan attached to the engine, it must release @ 20 - 30 extra horses?
You get too many more flags you're going to have to buy bigger shop
Pretty soon he could open a candy store to help fund it!!!😂😂
I am just a bit concerned with that oil filter failing at 104 psi. (17:21) The stress on the oil pump driveshaft must be horrendous! I wonder how much power the pump is consuming at that pressure? Wonderful video, Nick...thanks so much again!!

yeah! thats a beautiful weld on aluminium ... and you shouldn't grind down those welder swirls as they provide extra strength
In 1972, I bought a Plum Crazy & Black T/A from a friend who blew up the engine racing (it was a good death). He bought the car new and said it had 330HP & 370Tq stock. He bumped it to almost 400 for racing and that's when it lunched. I changed the K frame and dropped in a 426 Hemi prepared by Otto Candies. Wish I had never sold it ... ^v^
Buddy you got so excited opening up the chocolate! You know me with chocolate ah
The NHRA refactored the 340 4 valve from 275 hp to 350hp based on the e.t. The 290 hp rated engine made even more!
Sweet a Nick's Garage episode during this quarantine!
Excellent Edit. Considering.
Wash your hands and cover your mouth folks.

I always thought the engines of that time period were always under rated by the manufacturer for some reason.
Yes and no. Back then, they were rated at gross HP, not net. Net hp is how the engine is installed in the car, gross measured higher.
Insurance company s weren't happy with the muscle car craze of the 60s/70s so the big 3 always underated them to be keep the premiums down
My guess was 312hp Nick. You did good work ....
Words from a PRO;
'...People say Six Packs are a lot of work but you get
used to repairing them...'
Ahhh it's got a Greek rod 🤣🤣🤣😜🙊
Sounds like it has quite the bog before it picks up again, is that specific to six packs?
k w. On the Dyno, yes. But in the car, no issues.
325 HP would be my guess on the 340 refresh.
Cool. Thanks for playing along.
I've always loved 340s. I had a 1970 340 Duster, I wish I had it back. As I remember back then NHRA refactored the HP for the 340 4 bbl from 275 HP up to 325 HP. Although this is a 6 pak motor the HP doesn't surprise me.
What a combination !
American engine , Italian Body and with a Greek Rod
Great stuff Nick !
Stay safe !

THE 340ci IN GENERAL WAS A HIGHLY UNDER ESTIMATED ENGINE IN STREET RACING. IT WOULD BEAT DOWN ON THE CHEVY'S BUT WHEN IT CAME TO THE FORD'S. THEY HAD LOTS OF TROUBLE BEATING THEM. MY FRIEND JACK'S COUSIN CHRIS WHO WAS KNOWN AS THE SPARTAN. HAD A 1965 MUSTANG/STICK STREET DRIVEN CAR THAT RACE ON MOSHULU PARKWAY UP IN THE BRONX IN THE EARLY 1970'S. WITH A BASELINE 190HP 302 THAT CAME OUT OF GRANDMA'S STATION WAGON. THE LOWER BLOCK WAS COMPLETELY STOCK AND THE HEADS WERE PORTED AND POLISHED ON THE EXHAUST SIDE ONLY. IT HAD A HIGH LIFT CAM, 750 HOLLEY DOUBLE PUMPER, EDELBROCK ALUMINUM MANIFOLD, SODIUM FILLED EXHAUST VALVES. HE TOLD ME THAT THE CAR REVVED SO HIGH THAT HE CONSTANTLY TORE UP THE TIMING CHAIN AND HAD TO FREQUENTLY REPLACE THEM. THE CAR BACK THEN RAN 11.57'S CONSISTENTLY AND AT TIMES FASTER. THEY TOOK THIS CAR OUT TO NATIONAL SPEEDWAY IN LONG ISLAND AND TERRORIZE THE TRACK. THEY JUST COULDN'T BEAT HIM. IN THE END THEY PUT HIM AGAINST BILL GRUMPY WHO WAS RUNNING A BIG BLOCK 396 CAMARO. GRUMPY BEAT HIM BY ONLY 2 1/2 -3 CAR LENGTHS. YOU HAVE TO GIVE THE SMALL BLOCK FORD BIG CREDIT. I KNEW A GUYS WHO RAN A MUSTANG CALLED BOSS HORSE IN BAYSIDE QUEENS WHO WAS RUNNING 10.88 WITH A 289ci. AL RESPECT A LEGEND WHO RACED ON MOSHULU PARKWAY. HE WAS A BLACK FELLOW ABOUT 6'5", A SUPER OF A BUILDING WHO LIVED AND BREATHED FORD. AL RESPECT AND CHRIS WERE BEST FRIENDS AND SHARED THE APARTMENT TOGETHER. HE BUILT CHRIS'S 302 ENGINE AND AL RESPECT RACE A 1970 SUPER COBRA JET MACK 1 MUSTANG. AL RESPECTS MUSTANG NEVER LOST A RACE. HE MADE HIS LIVING RACING THIS MUSTANG FOR BIG MONEY. PEOPLE WOULD COME FROM ALL 5 BOROUGHS TO RACE HIM AND HE BLEW THEM ALL AWAY. FROM HEMI'S TO 427 L-88. HOW FAST WAS THE MACH 1 MUSTANG WAS NOBODY TRULY EVER KNEW. BUT WHEN HE RACED CHRIS WITH HIS MUSTANG THAT DID 11.57'S. HE LEFT CHRIS IN THE DUST. I HEARD UNBELIEVABLE STORY ABOUT AL RESPECT FROM CHRIS, BUT NEVER MET THE MAN PERSONALLY. I MET A MOVIE PRODUCER AROUND 10 YEARS AGO IN MANHATTAN. AND I TOLD HIM THAT I WAS INTERESTED FOR YEARS IN MAKING A MOVIE ABOUT THIS FELLOW AL RESPECT. WHEN I TOLD HIM THE STORY HE TOLD ME IF I WAS TO LOCATE AL RESPECT THAT I WAS TO COME BACK TO HIM. HE ALSO TOLD ME IF HE WASN'T ALIVE ANY LONGER. THAT I WAS TO TRY AND SECURE THE RIGHTS FROM HIS FAMILY TO MAKE A MOVIE ABOUT HIM. SADLY MY FRIEND JACK PASSED ON AND HE WAS THE ONLY WAY OF GETTING CONNECTED WITH HIS COUSIN CHRIS. THIS SUMMER I WILL TRY AND FIND JACK'S SISTERS AND THROUGH THEM I WILL TRY AND CONTACT CHRIS. IF THIS EVER WAS TO BECOME A MOVIE. IT WOULD BECOME AS BIG AS WHAT BOB GLIDDEN DID DURING HIS PROSTOCK YEARS.
I would like to see a video on that dart
Another Great Video...l was hoping for 310hp on the 340...couldn't believe the numbers tumbling on the Dyno screen...325+ hp & wanting more - good build...& I really like the blue notchback barracuda...l can look at that car and tell - somebody took the time & spent the money
I think the 3 deuces is too much for a little 340, a single 4 barrel probably put up a little more power but it's just not going to look as good as the 3x2's on a Challenger.
I raced a 69 340 and surprised some small block Chevy and big block Pontiac owners including myself. I didn’t win enough to race more than four years though.
Stay safe nick i wish you and you're family the best threw these hard times
Nick is practicing Social Distancing with 2 camera men in tight quarters.
Thanks for caring. Remember, this video was shot two weeks ago, just before our area went into lockdown. Nick only has one camera guy and we were in a negative pressure room. That dyno extraction fan sucks .. literally. We are still trying to keep the videos coming, but we are using more zoom lenses now, staying 2 meters apart and all the rest. We really appreciate your concern, and we balance that with understanding that everyone needs some entertaining distraction while we all get through this.
@@NicksGarage We appreciate it!
@@NicksGarage that and the camera mans arms are 6 feet long not to worry
@@NicksGarage Nick, no worries. Your content is probably the best produced on TH-cam for the car culture. Do what you can and stay busy! Be safe out there!
