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...
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!
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!

@@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!
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.

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.
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.
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 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 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.
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
Hi Nick from Lincoln Rhode Island. I want to tell you what a great relief it is to see you and your crew for 34:27 this time. In these troubled times you hang tough thank you for that!
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
Makes me wish I could be out rebuilding the olds 307 I started. But with this virus going around I'm staying at home. Always like watching your dyno videos. Stay safe Nick
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.
Love all your great videos Nick. My wife and I both own and drive 2013, 2014 Dodge Charger RTs, both AWD models. We also have a 2013 Chevy Camaro 2SS. We LOVE them! God Bless You and keep up the great work!
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.
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. 🤓
Nick, I worked in a speed shop specializing in MoPars back from 1963-'69. We also worked on some GM products. When a Hemi rolled in it was awesome but I had a thing for Six-Packs like you. I always thought the 340 never got the love and adoration it deserved. Such a handsome engine too especially as a Six-Pack. I loved this dyno run and enjoy your channel so much. Like my old boss you have a special love and attention to detail with these great engines and cars. I surely miss those days that were interrupted by the US Navy! lol
Service stations were fantastic places for teenagers to hang out and learn about cars. You’re so right, Nick, service stations have joined the chimney sweepers and dinosaurs. Keep up the good work and stay safe!
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.
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.
Well Nick. In these days of queuing just to get to the security to try to get in supermarket to try to buy food that is very rare now. I See Nick being Nick when i get home. VERY big thanks from Australia Nick.
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.👍
@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.
Excellent test. Enjoy all of your work. Suspected back then the 340 6 Pack was underrated and you proved it. Thank you for the information and entertainment.
Good Morning Nick! Locked down in Seattle. Enjoy your channel, better than anything on TV! I do not have a muscle car but I am restoring a '47 Willys Jeep....
Nick. Always enjoy your shows. My guess was 340 hp. Had and raced 340s in the 70's. These engines can rev past 5500 and will make more power at higher RPM with the right camshaft. Miss those days which is why I love your show. Brings back a lot of memories. MOPAR forever!
@@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.
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.
Hi Nick and Nick’s Troupes, I hope all you guys are healthy and safe. I was just thinking about a video I would like to see you make. I am curious about the functioning of the 3 carburetors in a 6-Pack and in duel quads. I am interested in which carb controls the choke, the idle, and how the power gets introduced through them. Thank you ALL for the time and effort you put in to the making of all the videos you produce. I look for them first when I get on You Tube. And right now the entertainment you provide to so many people, is worth so much more than you can imagine. Thank you so much!
I too love your videos, enthusiasm and the view from above of the carbs in action. Keep up the good work. Oh yeah, I love the naturally aspirated engines as well.
May the great team at Nick's Garage be safe and healthy. The videos bright up my day and the funny sports are priceless... CANDY... you got me to laugh out loud that my wife thought I went nuts. Yiassou!
stay safe NIck ! always liked the 340 ! and cant wait to see the keeper drive in a car... im from California and grew up on See's ...that stuff is better that any drugs... carful with it LOL
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.
They (the factory) say's they ran 290 HP. Everyone knew that it was probably around 350 or maybe 375. It don't matter, it's just nice to see one run. Thank You Nick for bringing this to us. Ronnie.
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.

Hey Nick I just wanted to say thanks for all the great videos you do. The 340 6 pack is my favorite motor my dream car is a 1971 Cuda 340 6 pack 4 speed black on black
Nick i love watching nicks tricks cause reminds me of my dad he thought me all the same tricks every time i see one of ur tricks i already know them but remind me of my dad thanks nick ur true old-school
l had guessed it would make 325 HP at bored over....Shuck's Nick you got the best Car...Stuff on youtube..By far...George has made all of this come true.....For us to watch....l hope you know that....Love you''all.....Super car stuff...God Bless truly...Thanks very much indeed...!
475 wow i was way off! And as I always say it's always a good time here you put on a great show I miss seeing Vasily on scene. The boy that was nice to see how those carburetors worked in sync. The ones that work for you and are around you are very fortunate to learn the awesome tricks of the trade I mean you build some awesome engines and beautiful cars. Always a good time here always. You got some lucky workers that get to learn from you. I would have paid a fortune back in the day just to be taught by you. As always great show can't wait till the next one.
Hey Nick, I saw an interesting hemi story over the weekend. It's called "Hemi in the Basement" here on youtube. It's about a couple of guys that were racing a 70 cuda in the seventies. They needed to remain competetive so they bought a '67 Belvedere GTX convertible with a hemi(1 of 17) and put the hemi in the racecar. Both cars were purchased from the estate by one buyer.
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
Great show Nick Out of adversity comes diversity. I hope this present world situation brings collective thought and rekindles passed trade disciplines. Excellent viewing from Tasmania, Australia.
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.
Man, that 6 pack didn't bog down as bad as first loaded i thought it would. Nick,I had a friend in high school (73-75) that he put a 340 6 pack in a 71 Plymouth road runner back then! MAN, that thing could REV in such an heavy car damn!
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.
"W'ell take it from there" love it when you say that Nick. It symbolizes taking things one step at a time, a great trait to practice at work and especially life itself. What an awesome channel guys! Great job producer man! Another Top Notch product from the guys at NICKS GARAGE!!

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!
Hi Nick from Lincoln Rhode Island. I want to tell you what a great relief it is to see you and your crew for 34:27 this time. In these troubled times you hang tough thank you for that!
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??.
Dr. Nick,years back my old friend had a Duster that had a 340 6 pack,thanx for all that you do for us in these strange time's,please be safe,cheers.
good morning Nick man i love the sound of smaller C I engines, keep safe thanks
Morning!
Makes me wish I could be out rebuilding the olds 307 I started. But with this virus going around I'm staying at home. Always like watching your dyno videos. Stay safe Nick
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.
Love all your great videos Nick. My wife and I both own and drive 2013, 2014 Dodge Charger RTs, both AWD models. We also have a 2013 Chevy Camaro 2SS. We LOVE them! God Bless You and keep up the great work!
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.
Your knowledge and passion for old muscle is a great thing to watch Nick. Thanks for this during these odd times.
Thanks, Kelly.
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. 🤓
Nick you are a Treasure to the Muscle car world. Thank you for all the heart and soul you put into your work. Or is it Love? Bravo sir, bravo.
What a combination !
American engine , Italian Body and with a Greek Rod
Great stuff Nick !

Nick, I worked in a speed shop specializing in MoPars back from 1963-'69. We also worked on some GM products. When a Hemi rolled in it was awesome but I had a thing for Six-Packs like you. I always thought the 340 never got the love and adoration it deserved. Such a handsome engine too especially as a Six-Pack. I loved this dyno run and enjoy your channel so much. Like my old boss you have a special love and attention to detail with these great engines and cars. I surely miss those days that were interrupted by the US Navy! lol
Roger. Good old days.
Sweet a Nick's Garage episode during this quarantine!
Service stations were fantastic places for teenagers to hang out and learn about cars. You’re so right, Nick, service stations have joined the chimney sweepers and dinosaurs. Keep up the good work and stay safe!
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.
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.
I would check the oil pressure relief spring. My 302 Mercury was blowing oil filters off when it jammed...
Thanks Nick and Team for Keeping us entertained, Uncle Tony's Garage brought me Here.. daily driver 1968 Dodge Dart everyday and Everywhere..
Right on.
Stay safe nick i wish you and you're family the best threw these hard times
Well Nick. In these days of queuing just to get to the security to try to get in supermarket to try to buy food that is very rare now. I See Nick being Nick when i get home. VERY big thanks from Australia Nick.
Nick is probably the best boss you could ever have. Wish my boss was as cool.
The second job I ever had was in a full service gas station,way back in the 80`s.Learned so much about cars.
"The missing link." Priceless!
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.👍

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.
Excellent test. Enjoy all of your work. Suspected back then the 340 6 Pack was underrated and you proved it. Thank you for the information and entertainment.
Thank you!
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.
Good Morning Nick! Locked down in Seattle. Enjoy your channel, better than anything on TV! I do not have a muscle car but I am restoring a '47 Willys Jeep....
Darren. 47 Jeep. WWII army style. My favorite.
I just pulled one of those transmissions out of a IR carbed 1967 Shelby GT350 I'm working on, interesting
Thanks Nick, you’ve got an awesome operation. It’s interesting that the factory numbers were posted @ 5000 rpm. Motor was capable of sooo much more.
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
Nick. Always enjoy your shows. My guess was 340 hp. Had and raced 340s in the 70's. These engines can rev past 5500 and will make more power at higher RPM with the right camshaft. Miss those days which is why I love your show. Brings back a lot of memories. MOPAR forever!
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.
I love your coverage of so many engines i developed. I often think of visiting your shop but i I'm staying in lock down now.
Thanks for being careful. The shop is locked down too.
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.
Hi Nick and Nick’s Troupes, I hope all you guys are healthy and safe. I was just thinking about a video I would like to see you make. I am curious about the functioning of the 3 carburetors in a 6-Pack and in duel quads. I am interested in which carb controls the choke, the idle, and how the power gets introduced through them. Thank you ALL for the time and effort you put in to the making of all the videos you produce. I look for them first when I get on You Tube. And right now the entertainment you provide to so many people, is worth so much more than you can imagine. Thank you so much!
I was guessing 325 because thats what my 340 six pac had with a racer brown solid lifter cam.
My favorite small block mopar. 335 hp guessing
a good call.
I too love your videos, enthusiasm and the view from above of the carbs in action. Keep up the good work. Oh yeah, I love the naturally aspirated engines as well.
Good power but it's only half the story, the 6pack smooth cruise motor.
May the great team at Nick's Garage be safe and healthy. The videos bright up my day and the funny sports are priceless... CANDY... you got me to laugh out loud that my wife thought I went nuts. Yiassou!
Haha!
Tom. Tell your wife I have ION chocolates hiding in the engine room. After hour snacks. Yiassou Tom.
stay safe NIck ! always liked the 340 ! and cant wait to see the keeper drive in a car... im from California and grew up on See's ...that stuff is better that any drugs... carful with it LOL
small block mopar! LOOOVE the sound of mopars more than any other brands!! Thanks for sharing this Nick!!
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.
They (the factory) say's they ran 290 HP. Everyone knew that it was probably around 350 or maybe 375. It don't matter, it's just nice to see one run. Thank You Nick for bringing this to us. Ronnie.
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.

Hey Nick I just wanted to say thanks for all the great videos you do. The 340 6 pack is my favorite motor my dream car is a 1971 Cuda 340 6 pack 4 speed black on black
Damn the oil pressure is good over 100 PSI at 5300 RPM LOL!!

475 wow i was way off! And as I always say it's always a good time here you put on a great show I miss seeing Vasily on scene. The boy that was nice to see how those carburetors worked in sync. The ones that work for you and are around you are very fortunate to learn the awesome tricks of the trade I mean you build some awesome engines and beautiful cars. Always a good time here always. You got some lucky workers that get to learn from you. I would have paid a fortune back in the day just to be taught by you. As always great show can't wait till the next one.
Buddy you got so excited opening up the chocolate! You know me with chocolate ah
Hey Nick, I saw an interesting hemi story over the weekend. It's called "Hemi in the Basement" here on youtube. It's about a couple of guys that were racing a 70 cuda in the seventies. They needed to remain competetive so they bought a '67 Belvedere GTX convertible with a hemi(1 of 17) and put the hemi in the racecar. Both cars were purchased from the estate by one buyer.
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
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.
325 HP would be my guess on the 340 refresh.
Cool. Thanks for playing along.
Thank You for all of the great videos Nick ! It’s just about as interesting and knowledgeable as it can get !!!
Glad you like them!
I would like to see a video on that dart
Great show Nick
Out of adversity comes diversity.
I hope this present world situation brings collective thought and rekindles passed trade disciplines.
Excellent viewing from Tasmania, Australia.
Pretty stong for a small block
An engine that just shouts 'Where's the other carb!' one missing!
Seriously though, what an engine and as always Nick is your man to build/tune it.
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.
Man, that 6 pack didn't bog down as bad as first loaded i thought it would. Nick,I had a friend in high school (73-75) that he put a 340 6 pack in a 71 Plymouth road runner back then! MAN, that thing could REV in such an heavy car damn!
Ahhh it's got a Greek rod 🤣🤣🤣😜🙊
We are with you in Spirit Nick..
We all are practicing social distancing.
Great Video...
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.
