As a small block guy, i gotta say, that, to me, that 340 is 1 of the best sounding engines i've heard on your dyno. Absolutely love it. More small block stuff please Nick. Great episode. Listen to that thing scream ; )
I love how Nicks makes sure the engine is tuned correctly before he starts romping on it to get numbers. Years and experience allow this kind of patience :)
400 horses, we're in 440 country with that number, and that's a beautiful thing!!! no worries Nick, I know you'll hit it, and then some!!!! I was guessing around 50 horsepower less, oh well, I'm glad I was under, so we get to see this baby sing a stronger song than I thought!!! thanks again guys.
I predicted 435 HP and 415 lb.-ft., was close on torque but Eddy heads let us down on HP... those heads don't flow enough to match up well with that 245 degrees duration at .050" lift '500 HP' cam !!!
after the first Dino and finding out that the crankshaft was total Junk I put a 340 crank in the 318 for the 72 satellite. Even with the thermal quote that engine runs great now, but a 340 would really wake that car up.
Waow this is only part one! How much power can you get out of a 340? The time has come This is gonna be fun Nick has got to break in a brand new cam Warming her up for 20 minutes is the plan Nick is the man!
@@OldGriz708 the 340 was a failure? Umm, I think you are a bit dim if you think that. The 360 came to make up for the drop in compression in the early 70’s.
it another great moday with Nick and the gang. just in time as well its my afternoon coffee break time :). the resturant i work for has been shut down for a month now so i have been home rewatching all the videos.

Good Morning, Nick and crew. No better way to start a Monday than a hot cup of coffee, and Nick's Garage. The sound of horsepower, and the smell of gasoline in the morning, oh yeah!! The 340 didn't make as much as I thought it would, but it will still be a great engine in a lightweight car like the Demon. It will be a blast to drive on the street. I loved the video George, very entertaining.
@@NicksGarage I'm looking forward to more Charger 500 updates as well, along with a lot of others who watch Nick's Garage. I hope to see the Charger back at Nick's soon.
@@eugenecastles7475 . I had a talk with Rodger this morning. I need the car back so I can start putting it back together. He has Fern back working on the Charger full time since last week. He had taken all the latches and hinges to start lining up the doors, hood and trunk. I was told that oliver was working on the Charger during the weekends. Many are asking about the 500. Let's get going.
Morning Nick, Leo & George, pity the dip stick is leaking but no biggie. That carb sure looks the part Nick and hey glad to see you using it. Just got a coffee so of to watch part two.
Ok, I didn't realize you were going with non stock parts. I know what kind of power that can be made with the LA Chrysler block. You have an excellent set up, Nick. Lots of power!
It's so cool, as well as educational watching these tests. When it comes to getting the most performance out of any engine, Nick is a old school perfectionist! However, I do have point out that the starter needs a couple of shims, its whining pretty good on starting.
Happy Canada Day to our hotrod brother and sisters up north. Thank you for being one of our greatest allies. I hope y'all have an amazing day celebrating. God bless.
I was just on a dyno with my brother's 340. They just shut off the fuel supply when it's time to jet the carb, the engine will stall after the fuel bowls are dry. No need for a drain cup!
@@BuzzLOLOL sbc only had better and more aftermarket parts avail. Mopar small block has been proven to be more effiecent valve angle than chevy or ford small blocks. It also makes it a pain in the ass to run headers for.... so chevy won out in a sense.
Love our aussie muscle cars.. there is a thing on youtube that you can look at.. its called narangba chook shed muscle cars and its worth seeing.. i even told nick from here about it
@@nickpanaritis4122 hey Nick. No, sadly it is back at my shed after ANOTHER shop messed me around. Up on the stacker hoist now keeping the dust off my driving muscle car! The engine is done. I'll get a drive of Kowalski before I get to drive mine again I think 🤣
I did some math, with the Air fuel ratio crossover to the Brake specific fuel consumption, once the secondaries take over should be in the 12.5 to 12.7 range with the BSFC at the upper range falling between .520 minimum to .570 maximum on this engine. Since your running long tube headers you started a little lean as far as the carburetor goes. We would start here: To find the proper jetting for the primary's, we un-hooked the secondary linkage And tied off the secondaries to prevent from opening as the vacuum drops.This should be observed close to near max on the torque rpm on the primary's only. Observe the rpm where AFR and the BSFC drops off. Add jet size till it also rises then the power falls off, then go back to previous jets used. When this is found do the secondaries next. Increase the secondary jets two sizes at a time till the power falls off, then go back to the last jet size used, adjust timing as you go. (FYI, a lean condition with too much timing may knock /ping or burn a head gasket) You should get the best this combination will give you after this. This is how we set up the carbs for a specific heads, cam and intake on any engine. Food for thought. Note you might have to adjust /bend the secondary linkage ( not much)to keep the secondaries from coming in a bit too early. Need to come in where the primary's start falling off. Before the haters start.... Yes, this requires some major homework and when this is dome you have a great running engine. I hope my experience is helpful
i enjoyed the video when you ran 3 different types of exhaust on mopar 440 that was awesome. who would've thought factory exhaust would perform as close to headers!!
It's what I expected... build a few of these. Used to use 273 crank shaft, eagle h beam rods, Ross pistons, 340 j heads and one w2 head,(still have in a demon), when I balanced the asembly they took weight off the 273 crank. You can imagine how quick reving it is!
I had a 340 back in the day. What would be interesting to see on your dyno is a small block MOPAR wth Direct-connection W2 heads and/or W@ Econo heads. Apparently, these will make the small block sing.
That's about right hp maybe squeeze a little more hp and tq out of it with spacer and 1 5/8 headers. We had a 13.5-1cc 340 stock rod&crank, 312 dur 630in lift general kinetics solid cam with a set of fully ported W-2 2.08 valve, victor w-2 intake 950 holley hooker 1 7/8 headers never had on dyno Ran low 11's on engine yanked wheel about 4 inches in a shorty dodge van.
Nick, I've been using Permatex Anaerobic Gasket Maker in the blue squeeze tube for dipsticks and hard to seal small engine parts. Works where the gap is small and even works with gaskets. Can the distributor mechanical advance be adjusted to come in higher? Nice to see a test on the little giant killer 340 Mopar. Masterful job building it, as always at Nick's Garage.
Had a buddy with a NA340 making 600+hp it pretty much only ran 6000-9000rpm. Drag car of course so it was a lot wilder build. Stock factory forged crank and oliver rods.
@@BuzzLOLOL I know the manufacturers run these new motors with aluminum heads etc. Run A little warmer, wonder if that would have made a difference and maybe a single plane intake? No expert, just wondering!
@@donaldcoalson4347 The aluminum heads run cooler especially in the combustion chambers so it allows you to run more advance if necessary & also allows you to run a higher compression ratio piston without pinging & detonation problems on pump gas . I think the dual plane intake might be choking off power as well & a bigger cam with more duration will help it make more power as well but who knows if the owner is willing to swap out the cam for something bigger . He could go with 1.6 rockers to try & get more lift out of the cam to work those heads more if they weren't used on this build already but changing to a 1.6 rocker only affects lift not duration . It seemed to me that also this engine wasn't really spinning that high of RPMs shutting down under 6,000 to me it looked like which is strange being most of the 340s will rev right to 6,500 or more . I am kind of disapointed in this build because he's just under 400 hp with all this stuff on it when a buddy of mine just dynoed his 68 440 4 barrel engine he basically did a mild rebuild on for his 68 Plymouth GTX convertible that just was bored over .030 stock 906 heads done with new valves guides & seats but no porting or over sized valves or bowl blending but used a dual pattern cam that wasn't much more than what it had stock with the lifts & durations & just a edelbrock performer intake through the stock exhaust manifolds & it made 400 hp & 460+ torque down at 4,200 RPMs after it's break in & the rings seated so something isn't right with this 340 . I figured maybe Nick would have tried a spacer between the carburetor just to see if the extra plenum area would help with the hp or not because some times it does some times it doesn't but maybe that's part of the next video 🤔 .
@@donaldcoalson4347 - Eddy RPM intake good until about 500 HP and that 245 duration cam wants to make 500 HP, but those heads holding it down, plus parts are mismatched to each other... carb. too big... cam too big...
Are used to run a 480 left with a 299 duration in them with a 3500 stall speed 410 high volume trw oil pump 650 cfm dual pumper flat top piston12’s in a 72 demon 727 Fairbanks full comp
Your cam prolly a better match... I predicted 435 HP and 415 lb.-ft., was close on torque but Eddy heads let us down on HP... those heads don't flow enough to match up well with that 245 degrees duration at .050" lift '500 HP' cam !!!
The 340is hard to find down here in Florida must have sold a lot more of them in Canada,I am of the opinion that the 340 is Mopars most powerful small block
Love the 340 snap for a small block that’s my world not a small block Chevy god even knows them things are screamers 8k rpm 350 / 350-360 hp man I remember those 327 having 350 hp factory
I predicted 435 HP and 415 lb.-ft., was close on torque but Eddy heads let us down on HP... those heads don't flow enough to match up well with that 245 degrees duration at .050" lift '500 HP' cam !!!
Problem is now the good intake manifold companies have big single plane intakes that flow better than the 6 pack set up as well as some dual four barrel stuff only using 1 big carburetor which is not only cheaper to buy but also easier to tune & stays tuned better than a multiple carburetor set up . My buddy had a 6 pack on his 69 440 charger back in the late 70s & it was a pain in the ass always having to adjust the mixture screws & getting the linkage & carbs synched after only a few tromps on it either at the strip or hot rodding it on the streets I remember . They look cool but back in the day the mixture screws would often loosen up once the cork seals went bad that helped seal the mixture screws off on the float bowls then it wouldn't idle right plus the linkage would get worn out & they could be more work than it was worth but they sure looked cool especially when at the gas station checking fluids & guys would come up & look at it & ask questions about how it performed which wasn't bad but if not kept in tune it could hurt you in a race as well as drivability.
What are the specs of this cam please? and Do you change the oil filter and engine oil after your cam break in but before you lean on the engine for the power runs?
If it's running lean it should help with the pinging making the air fuel mixture more rich..:)..Just thinking out loud..!!..Maybe put a spacer plate on the carb for those last few HP..
340’s alway surprise people! Giant killer! Id live to roll an A-Body 340 Car!! I should do something with my 340! Id guess 360hp on this one maybe more!
Simple fix on that oil leak pull the dipstick out put a screwdriver in there that the handle is just a little bit bigger than the tube take a hammer and tap it into place works every time
Jeff. Not really. It all depends on your cooling system. Very rare I have a 440 run hot. Check out my Kowalski Challenger. It is overbored .055, 10.6 CR, and all original factory cooling system. No issues on hot days.
*NICK!* Needs more RPM'S, my man!! Just sayin' - it shouldn't be "all in" at that speed with those heads and that cam. Just my two cents... Trivia time, Mopar guys: Other than the 426 hemi itself, what was the only other performance engine design that came out of Chrysler Engineering to never have a more "pedestrian"/regular service engine as an origin that it came from? Answer: The 340. There were no "passenger car" or truck versions of the 340 - it was always a performance engine, from the get-go, whether in Magnum or T/A versions.

@@BuzzLOLOL I defer to your apparent expertise there - but when Nick put spacers under the rocker shafts he got the HP he was after, so the heads must have had that much in them. The mistake people make with the Edelbrock heads is that they're opyimized right out of the box. They aren't - just like any other head, they need some work to realize their potential.
@@moparedtn - Shims under rockers are just to get the valve lash correct... if shims give power, then something was wrong... or the correct length pushrods could have been used...
My 71 340 with the same edelbrock set up keeps leaking oil passed the distributor o ring. Tried changing it and adding a gasket, still leaking. What am I doing wrong???

Great to see a 340 Nick! I love my 340! Thanks for sharing!
The Legend is, Chrysler underrated the 340 because it was making numbers in big block territory.
Insurance companies either would mot insure high HP motors or their rates were too high
That's the legend, the reality is the 340 was a failure and was quickly replaced with the 360 and it wasn't much better.
legends is another word for BS..

@@donaldcoalson4347 - Eddy RPM intake good until about 500 HP and that 245 duration cam wants to make 500 HP, but those heads holding it down, plus parts are mismatched to each other... carb. too big... cam too big...
Most laser thermometers can only read so high, that one says fail because its beyond it capability.
Plenty of cam, head flow, CR and yet it still can't make 400. Shocked
Old school water bottle to check header tubes for cylinder function still the best way. No exact temperature specs. No batteries needed.
Old skool definitely works but so does new tech. We used both when servicing our fleet of diesels (before I retired 11 years ago).
does anyone read flame patterns on plug ceramics anymore?
Headers a must on the 340
I’m late but I made it! I couldn’t watch while at the dentist 🦷 lol
No worries, Zach. Hope it wasn't too painful.
@@NicksGarage just a cleaning 😁
Giasou Nickola, finally caught up 👍
I'm getting ready to watch the dino test and the 340 I'm saying about 5:25
the big block killer
All i can say is, Mopar Magic
Are used to run a 480 left with a 299 duration in them with a 3500 stall speed 410 high volume trw oil pump 650 cfm dual pumper flat top piston12’s in a 72 demon 727 Fairbanks full comp
Your cam prolly a better match... I predicted 435 HP and 415 lb.-ft., was close on torque but Eddy heads let us down on HP... those heads don't flow enough to match up well with that 245 degrees duration at .050" lift '500 HP' cam !!!
Hi Nick , another great video from Nick and his crew >>> what RPM do you like all your timing in at for the street . like mine in at around 3000 rpm
Car. Same as yours, 3000.
Nothing like watching the clock on RUclips
Last 340 vid of nicks was a basic overhaul with a mild lunati voodoo and made 365 or somthing like that.
The 340is hard to find down here in Florida must have sold a lot more of them in Canada,I am of the opinion that the 340 is Mopars most powerful small block
Love the 340 snap for a small block that’s my world not a small block Chevy god even knows them things are screamers 8k rpm 350 / 350-360 hp man I remember those 327 having 350 hp factory

Sounds like a ‘70’s movie music soundtrack.
I would also be curious to see what the difference would be between the 4bbl and a six pack
Biggest difference would be the huge headache of setting up and balancing 3 carbs, and the crap driveability when you can't
Problem is now the good intake manifold companies have big single plane intakes that flow better than the 6 pack set up as well as some dual four barrel stuff only using 1 big carburetor which is not only cheaper to buy but also easier to tune & stays tuned better than a multiple carburetor set up . My buddy had a 6 pack on his 69 440 charger back in the late 70s & it was a pain in the ass always having to adjust the mixture screws & getting the linkage & carbs synched after only a few tromps on it either at the strip or hot rodding it on the streets I remember . They look cool but back in the day the mixture screws would often loosen up once the cork seals went bad that helped seal the mixture screws off on the float bowls then it wouldn't idle right plus the linkage would get worn out & they could be more work than it was worth but they sure looked cool especially when at the gas station checking fluids & guys would come up & look at it & ask questions about how it performed which wasn't bad but if not kept in tune it could hurt you in a race as well as drivability.
CFM is CFM. That motor won't pull more than 625 cfm at 5500 rpm, anything over that is a waste.
Amazon says that drain cup "usually" ships within 1-2 months. I was gonna get one, maybe will wait a bit.
Wow! Thanks for looking at the link. Hope they can get some more in stock soon.
@@NicksGarage Well, they did. I have one ordered and it's on the way.
Oh yeah horse 🐎 power
68 roadrunner and a 70 GTX both ran hot in summer
Jeff. Where do you live ? Extremely hot ?
Is no PCV causing the oil leak?
What are the specs of this cam please?
and
Do you change the oil filter and engine oil after your cam break in but before you lean on the engine for the power runs?
new deserves to be hooked up to your super flow air mix meter
If it's running lean it should help with the pinging making the air fuel mixture more rich..:)..Just thinking out loud..!!..Maybe put a spacer plate on the carb for those last few HP..
Hey Nick, you ever run into any 340R engines? @Nick's Garage
340’s alway surprise people! Giant killer! Id live to roll an A-Body 340 Car!! I should do something with my 340!
Id guess 360hp on this one maybe more!
Right on!
What would help make MORE HP 3x2 or 4 bbl.
Simple fix on that oil leak pull the dipstick out put a screwdriver in there that the handle is just a little bit bigger than the tube take a hammer and tap it into place works every time
The 340 shot make around 400 hp with respectable torque numbers over 400 plus.💪💪💪😎🆒👍💯✌️😁😆💪🆒😎
Thumper carbs are like jewelry.
Nick did you by chance meet Cotton Owens down in Spartanburg SC. Your reaction remind me of him as you get involved in your projects.
What kind of Oil and or additive is being used??
I had 2 440s is it normal for those engines to run hot....in summer they both did no matter what
Jeff. Not really. It all depends on your cooling system. Very rare I have a 440 run hot. Check out my Kowalski Challenger. It is overbored .055, 10.6 CR, and all original factory cooling system. No issues on hot days.
Where were the pistons sourced? I need a set of .040 over and noticed the bore on the dyno set to 4.080. Brand?
Home. They are RaceTech Pistons. .040 overbore. Give me a call.
The starter sounds rough
need to know duration on cam lift meand little in determining how it will rev
Morgan. Look on video part 2.
@@nickpanaritis4122 i was in your shop a cpl years ago lol! but ill look after im done watching part 1 !
@@morganmclean1790 . If it is not there, email me for the cam specs.
@@nickpanaritis4122 watching it now brother!
put a spacer on it
*NICK!*
Needs more RPM'S, my man!! Just sayin' - it shouldn't be "all in" at that speed with those heads
and that cam. Just my two cents...
Trivia time, Mopar guys:
Other than the 426 hemi itself, what was the only other performance engine design that came out
of Chrysler Engineering to never have a more "pedestrian"/regular service engine as an origin
that it came from?
Answer: The 340. There were no "passenger car" or truck versions of the 340 - it was always
a performance engine, from the get-go, whether in Magnum or T/A versions.

@@BuzzLOLOL I defer to your apparent expertise there - but when Nick put spacers under
the rocker shafts he got the HP he was after, so the heads must have had that much in them.
The mistake people make with the Edelbrock heads is that they're opyimized right out
of the box. They aren't - just like any other head, they need some work to realize their
potential.
@@moparedtn - Shims under rockers are just to get the valve lash correct... if shims give power, then something was wrong... or the correct length pushrods could have been used...
@@BuzzLOLOL Well yeah something wasn't right, hence why it helped. :-)
My 71 340 with the same edelbrock set up keeps leaking oil passed the distributor o ring. Tried changing it and adding a gasket, still leaking. What am I doing wrong???
John. Does your engine have breathers ? If yes, put some teflon tape between the O'ring and distributor housing. Good luck.
Nick, have you ever had a cam flatten the lobes during break in?
With an Edelbrock Victor single plenum intake it would make 420-430 hp all day.
420 HP!!
