The best part of this is not just seeing the results of the dyno testing but also watching two great friends doing something together that they both enjoy.
I was just thinking the same thing. It reminds me of my best friend and I. We've known each other since 7th grade. Fifty years for me and Doug. Great comment ! Nothing better than a buddy that covers your back and vise versa. Someone you have SO MANY years with that there's no second guessing .
I had a 383 magnum , out of a 69 super bee, in a 69 charger , holly 780 cfm double pumpercrane fireball cam back in the early 70s the new cam was under 40 $, 3:55 rear gear , she would run like a bat outta h**l , never saw a 383 6 barrel, but I did get a nos 383 dual quad intake , gotta love the 383 , those were the days ! There was a fella with a 383 road runner ( built ) who was out running 440s , then I got a 340 duster auto bench seat, it had a big Carter, I was never beat, it would out run 440 six pack with no prob, that was fun fun fun !!! That 340 would wind up where it sounded like it was gonna launch rite through the hood, da*m , GO MOPAR
@@Welcometofacsistube ..Yes,but the 440 still stomped the 383...I love them both...I have several 383 engines and 6 383 hp cars,all restored by myself..four 68-71 B bodies,two E bodies.I do have more 440 cars,collected,restored since the 90's...My daily for 7 years was a 383 Magnum Super Bee then a 68 Charger R/T 440 Magnum both auto and 3.23 and were stock,you really notice the extra cubes and power/torque of the 4 4 0
I had a 383 hipo in a '68 chrysler town and country wagon. After some radial tires it was a wonderful drive. The 383 had enough power to make it loads of fun. Ask the kids in the back... lol
Chrysler started manufacturing the 383 way back in '1959'. From the day it was introduced demand for the 383 went through the roof! Within only 2 years of introducing the 383 Chrysler had to open a second engine plant just to keep up with demand for the 383.. When I was 16 years old my buddy's dad owned a 1960 Chrysler Saratoga with a factory equipped 383, four barrel in it. One afternoon my buddy took me for a ride in it. OMG COULD THAT CAR GO!!! Thanks for loving the '383' Nick; many of your fans carry treasured memories of that GREAT engine.
Originally in Chryslers they were actually putting 383 RB engines. 4.025” bore and 3.75” stroke only made them for a year or two because they couldn’t produce enough of the B version. ‘59 and ‘60 I believe
I like all American muscle. Grew up mostly a chevy guy but I am now obsessed with mopars! To me, the B and RB engine are mechanical masterpieces. Things I like...strong lower ends, external oil pumps, skirted blocks, one piece oil pan gaskets, distributor in the front, no coolant passages in the intake, good cylinder heads/valve train, and easy to work on and make power. This is a great video and a prime example of an engine I want to build soon. Just picked up a 383 core to rebuild and you guys give me the inspiration to get it done👍
Hey NICK here's a little tip for that "six pack stumble". Change ONE outboard carb spring in the secondary diaphragm to one range LIGHTER. A lot of guys back in the day would put a stiffer spring in so they came in later; that's wrong thinking. By just changing one spring to one range LIGHTER, that set of barrels opens just a tad quicker. When the velocity picks back up in the manifold, then the other set opens up. That way instead of getting one giant gulp of air all at once and getting a stumble while the motor tries to build up vacuum again to get the flow moving, it comes in more gradual.
@@mikes.1882 not bold thinking at all and I in no way question Nick's knowledge. I AM however a true gearhead and that's part of being a gearhead is shop talk and offering suggestions because maybe some of us have run into this before. TH-cam is just a different platform than what we had in the seventies. If Nick and I ran into each other on the streets and he said his six pack was doing this, I'd say have you tried that and vice versa. A true gearhead doesn't let his pride get in the way he talks to his buddies and gets suggestions. The days of street racing with grudges and top secret combos and unapproachable attitudes is over dramatized kids stuff.
I agree 100% with Mikes1882, in makes perfect sense. This way the engine thinks it has a 4 barrel, then surprise. The extra gas starts feeding the engine when it’s ready for it and the RPM’s are there for it. Too much gas all at once sometimes is not a good thing
Thanks for posting! This brings back memories of my Dad's 383 727 69 Roadrunner. Grocery getter in the family from purchased new that year and sold in 1999 due to his health. He managed to get low 13's out of the car with a min engine mods; Melling cam, Holley carb, a Holeshot converter and 3.91 gears. That engine was a reliable beast. Peace from Boston.
I ran a 68 Galaxy 500 with a 390- 6pack and never ever once properly set had to adjust a carburetor. For over 10 years. Always ran Great ! One of the Best car I ever owned. Always could make you Smile I’d drop the top and listen to that 6-pack , those 3 little Holley carburetor open 1-2-3 . They came in so good. Once there don’t mess with them. 😊
I love to see the school boy enthusiast in Nick. Anybody that loves the technology of these fossil fueled monsters can relate. My favorite was a screaming solid tappet 327 sbc I built for my El Camino. Made 7000 Rpm look like a stroll through downtown. These old engines are a symphony of technology, and an "old salt" like Nick..... the conductor.
Although we are Scandinavian and not Greek, Nick standing there holding his cup of coffee reminds me exactly of my grandfather. He was a skinny little guy too and he just moved like Nick does and he loved tinkering with motors too. He gave me my Tomcat nickname. Love the videos 👍
That has to be the running stroked 383 I've ever seen and what a great combination! A real journeyman mechanic! Well done and great video! Take it up to 6 grand.
I liked that torque curve that I saw at 33 degrees when you first ran the engine. Mine liked 8 initial and I made the advance come in at 2 stages. The initial stage was 2100 with 26 degrees and then the 8 more all in by 3k rpm. Beat emissions standards through 1974 model cars, got 20mpg on the highway, and 0 to 60 mph at 6.2 seconds on a standard 383 with torqueflight and 2.91 gears.
Fifty years ago, an old timer showed me a trick to "fix" the "half dead" carburetor. He crossed two spark plugs which, induced a repetitive crossfire/backfire through the intake upon a "snap acceleration". Carburetor fixed! Whatever was clogging the idle circuit was blown out and settled to the bottom of the float bowl and never came back.
Being from Sydney Australia it just makes me so joyful that a real Road Runner is on our streets I can just feel it's presents sick Niick I love to know where I might see this special car and even hear it
That is one fine setup. You squeezed a lot of hp and torque out of that 383. I would be proud as hell to run that in that Roadrunner. Theo will be kicking ass and taking names with that setup. Nick, you and Manny make a good team. George, excellent video quality and point of view.
I'm anxious to see what kind of numbers Theo's stroker motor makes on the Dyno. Lets see what the King of Mopar can squeeze out of this engine, here we go!!
@@NicksGarage The numbers didn't disappoint, Theo will have an excellent engine for his for his Convertible RR. It will be a nice cruiser with plenty of power, to destroy the rear tires. I always look forward to Mondays video. Well done George, awesome video!!
I've watched and learnt so much from Nick- I started talking like Nick. My mum asked me something and I said " why it does that I DO NOT KNOW!" Hahaaaa. Hello all from West Australia
You don't often see the 383 or 400 6 BBL's but when you do it's quite a treat! 40+ years ago my Mopar mentor buddy Bob built a 383 6 pack engine for his 70 or 71 convertible Challenger, what a spectacular car and engine. I don't remember the h.p. number but it was easily over 450+!👍 The convertible Challenger was a factory 318 car that was at a repair station around the corner from Bob's house. He drove by it and stopped in the shop to ask his buddy who owned the shop what the story was about the car. The engine was blown and the owner of it didn't want to fix it, so my buddy asked to buy it and the shop owner said he'd talk to the car owner. A few days went by and when Bob went by the shop again the car was gone. He went in to see what happened to it and discovered one of the mechanics who didn't know the shop owner was going to sell the car to Bob had sent it to the junkyard!😮 He burned rubber flying to the junkyard to hopefully save it! Luckily he was also friends with the yard owner and asked if he knew where the car was. Sure he said, aisle blah blah over there. Mind you this in in the late 70's so these cars were no big deal then. As he walked down the rows he wasn't seeing the car. He again asked the owner where it was,he couldn't find it. The yard owner said I know it's there, I just put it up there. Up there,up where? Well he wasn't looking up,it was on the top of three crushed cars!😲 Ahhh!!!
Enjoy watching Nick tinkering with old muscle car engines. Nick and I are about the same age and are both MOPAR nuts! God bless you Nick turning the clock back to our youthful times!
Nick, it saddens me to see any 383 ever again after Selling my 71' cuda. I thought 🤔 watching your channel it would put me in the Mopar Spirit, but instead reminds me of something I lost forever. Best Wishes Cuda guy.
@@NicksGarage thanks Nick you can only imagine selling you Kowaski Challenger. Once I was sent to Indiana. I drove to the Mopar dealership to order the Chrome tips for the Cuda. I drove my wife's Renault they was $100 each. They looked at me & laughed like I didn't have a 383 at home. It took sometime but I think direct connection or somehow they got their asses chewed because when I drove up in the Orange 🧡🍊 Big Block their faces 👀👀 was blank. They couldn't believe I drove it from down South to Indiana. I even went with my buddy Roadrunner Dude to the Mopar Nationals which was held that year Inside The Indianapolis 500 track. I bought a pistol grip shifter. The guy I bought it from removed the column shift & used a cutting torch to cut the floor boards to put a 4 SPD in it. It was purchased new in a town called Alice but a Automatic, he worked as a mechanic so he just changed transmission. It was a Original 383 Billboards & all but missing the Chrome tips. My dad had lung cancer later we found out. That damn Cuda wouldn't start for nothing We Trouble hunted down everything, then ROADRUNNER DUDE SAYS, did you check the VOLTAGE ⚡ REGULATOR!!!! My Dad was going to die & that $10 VOLTAGE REGULATOR STOPPED the Entire Engine From Running!!! Out of Rage I sold the damn thing. We replaced that $10 part on the driver's side engine Compartment & that 383 started up like lightning ⚡. I didn't drive to the Mopar Nationals I Rode Sidekick Instead in his ROADRUNNER. Car Love Lost in Time. Sometimes I think 🤔 the crap I get into could fill a season of THE TWILIGHT ZONE! Look you know about that little metal box in the Driver's engine Compartment. My one Chance for Two 383s to go together inside the grassy part of the Speedway. Sad but True. I couldn't make this stuff up. Still Love Cudas. One day down here I heard a large engine approaching, it was a 71' ROADRUNNER 440 SUX PACK . YELLOW & BLACK .
I had a friend back in high school in the 70`s that had a `70 Challenger R/T 383 4 speed. That car was nuts, man was it fast. Good times, it was a tire melter too, but not a six pack. I love dyno day! Here we go!
Thanks Nick for your hospitality Friday when I visited your shop. Thanks for showing me around and I enjoyed talking about cars, engines and the challenges of operating a shop. All the best . Hope to visit agin in the future Thanks again.
426 hp from 433 cubic inches, 485+ pounds of torque with the air cleaner on, with a smooth idle and very good vacuum. Not to mention its got cast iron factory heads. This is the engine you should make for everybody from this point on. This is going to be a tremendous street engine. Does anybody make reproduction cast iron exhausts from a Stage 3 Ramcharger wedge.? If not, then the best cast iron exhausts from the exhaust manifold test you made last year would be a nice second. Nick, whoever suggested to you to test a 6-barrel engine with the factory air cleaner on, he gave you a nugget of wisdom.
Nick a friends 383 we raced in a 70 Road Runner. 850 Holly with 90 jets. 1" spacer. Timing at 38⁰. Motor was balanced and bluprinted. Steel heads, big valves. Hydraulic tappets. Purple shaft cam. Forged pistons. Can't remember the rods? 6 pk rods maybe. Ran 11.8 on regular gas at first with led additive. It would rev to 6000rpm no problem. Standard crank, +40 bore. When the engine builder dynod it the dyno messed up and reved to nearly 8000 rpm lol. The noise was incredible!!! 😁 520 bhp and 640 torque! Eventually we tried a 150 Nos kit and got 10.2 on a quarter. Changed the cam for a custom grind. Little monster the 383!! Road Runner was stripped interior and two race seats and a roll cage.
You guys work well together - and the conversation adds interest and understanding. The three deuces was a fun piece of performance bling, actually useful for only a short period till the real high performance 4 barrel carburetors came out. I like the down the carburetors view as the engine runs ! Not always a safe place to have your face...
Goooood evening, gents!!!!! Man, I looove watching these dyno videos, seeing Nick scratching and clawing for every ounce of power he can get!!!! That’s a pretty good and quite interesting combination of the 383 bore with the 440 stroke: it would be VERY INTERESTING to see the results with a bigger cam and some semi-serious heads: I’d like to build that combo myself lol!!!! Nick and Manny make a great team, and George, your video production skills showcase everything perfectly: great week to you guys!!!!!
He's an old school artist! I've seen so many newer style engines, with fuel infection, electronic ignition, and "power adders", on the dyno on other channels, and their tuning is done with a keyboard. This is so much more involved, having to change jets, adjust timing with the distributor, etc. He's truly the Mopar Wizard!
Hi Nick, Manny & George great video guy's. If Theo not happy you can send it to my daughter for her AP6 Valiant she just shouted, kidding I hope Nick as that is one beaut rebuild with some nice numbers too. Thanks all and stay well till next time.
My ex father in-law graduated high school in 1969, and he bought a '69 Super Bee and a '69 Harley-Davidson Sportster. As he put it, the Super Bee "only" had the 383 motor, and he sold it in the 70s when gas prices skyrocketed. He still has the Sportster that he turned into an "Easy Rider" style chopper (complete with a hardtail, long forks, high bars, sissy bar, and purple metal flake paint with pinstripes) but he wished he has his old Bee, too!
I had a 1970 413 police interceptor motor, in a 1972 D100 Stepside. God I love that truck the most reliable thing I've ever had in my life, and it was the wedge motor, made tons of power. Just about gave it away, I'm so stupid.
Hey Nick, I just subscribed! I’ve been watching for a few years and love your videos. I like what your did with the 383 stroker. It’s nice to see something different. Last year I built a 400 that was not a stroker motor. I love the idea of the large bore and the short stroke of the 400. I put a 383 steel crank in it. I feel the 383 and 440 gets all the attention and the 400 doesn’t interest people other than for stroker motors. After my build I put it on a Dyno and made 457 hp and 463 torque. Used 906 heads, hyd flat tappet cam and runs on 91 octane. There are many 400’s out there cheap and can make big power when built properly. It would be nice to see something out of the ordinary in your videos like what I did. I’m sure lots of viewers would be entertained seeing something like that. Thank you and keep up the good work! Jake P, Minnesota
I enjoy watching you in your beautiful shop. I'm very impressed with your engine building skills. It's very obvious that you've been around the block a few times. I really like the ways you diagnose every problem! Thanks for your channel.
That centre carb isn't putting out the fuel the other outboard carbs are which might be the cause of the lean mixture at high RPM but damn that engine sounds good.
I'm thinking what you're seeing is without the air cleaner on. This is one of the thing's I'm curious of about those three two bbl setups though. Those Chrysler air cleaners are really low profile
The end carbs do have idle mixture adjustment screws. The factory carbs had them hidden behind plugs that were easily knocked out. Keep up the great videos much enjoy!
@@NicksGarage Uncle Tony's Garage put up a video yesterday about a bunch of Mopar parts he had just acquired, it might be worth your while to look at it.
Nice build Nick great numbers! its always great to see you and Manny working things out together. Almost the same numbers as my 440 bbl. Another excellent video George!
Nick, you are like me I don't say how good everything is to the end so I don't jinx it. I couldn't help but hear every time Manny wanted to say something positive about the build during break in you kept saying "we'll see."
Tell me if I'm wrong but the reason those air cleaner base plates are so big- they come right out to the rocker covers- is to trap the hot air coming off the engine so it doesn't go into the carbs. And it's angled to feed hot air out the back. Great design.
@@dartgts383 I just remember when Nicks brother put just the base plate on his hemi race engine, from memory, it picked up some horsepower over not having it. So it is doing something.
@@dartgts383 another good thing is you can actually tighten down just the base plate cos they've got those bars going over the carbs. Most air cleaners you have to put the whole filter and top plate on to tighten them down. So mopar really thought of everything.
Hey Nick,George, and Manny , was out of the loop for a bit . Love watching Nick & Manny working in the dyno room . George love those light colors in the dyno room too . You do great work with them .I pickup some of your lighting ideas and use in my shop ...
The horse power on my 69, road runner,383dualquad, factory in line,off a58plymouth,, with a little bit of modifying, pulled 460horses, and 510torque, and turned the eight mile in six seconds on the right rear tire going flat,had to let off the pedal about about a hundred feet from the light.
Incredible! The 383 didn’t always demand respect, goes to show simplicity rules…This will turn heads. HP, Smooth and tons of tire shredding Power. Well done Nick. Thank You Manny and George. Brotherly Love from Deep South Texas, Lee.
If you're just one or two percent short of your number, try running the oil a quart low. The engine isn't being subjected to launch, cornering, and braking, so, no harm should result. I used to work on a Pro Stock team, and one or two thousandths of a second can be the difference between making the next round or loading up the trailer. We used nine-quart pans with four quarts in them, along with some very sophisticated windage trays, to keep the oil away from the crank. When we had a "street" engine on the dyno, we would always run it a quart (or two!) low. That was usually good for four to five percent.
Love this! My old man drove a red 1966 coronet 440 model, 383 4 speed, when he was in highschool mid 70s era, people around him said that car could hurt some bb chevy feelings. Those sounded like the good days👍
You don't want any of your muscle cars engine components to be ingested That's why you need to head to Nick's Garage to get your 1970 383 Stroked and Dyno Tested Because Nick's Garage has never been bested This Stroker looks ready for some aggro It's another tremendous Nick's Garage show He's a lucky man is Theo I just can't wait to see how well it's gonna go Without some decent timing You might be late arriving It's perfection for which Nick and Manny are striving It's the essential research and development that is required before you strap it in and go driving This one looks tip top When breaking in a new cam you gotta keep her running you can't stop Theo has selected the correct muscle car shop It's Nick's Garage every Monday that brings the muscle car afficionados to the fray I give this 383 three cheers hip hip hooray
My father, when I was younger, ( now65) got hold to a set of heads from a company that cast them in a HEMI configuration, the relocated the valve angles to work on the (B) ? Block 383 and 440 short blocks so that you would have, basically a high reving torque monster HEMI, that thing, coupled to a TCI 727 Automatic, with a custom torgue converter could destroy a set of Firestone drag 500 slicks at the drag strip back in the 70's and 80''s he won many events, my father, (God rest his soul) was one of the innovators back in the day he had one heck of a reaction time and would smoke so many of those other drivers coming off the line, it was ridiculous and glorious at the same time, gave me the love of all things mechanical, I miss him he was a character and had a very odd sense of humor and could find, even when he lost a race, something funny in the moment, Nick is in that same group, keeping the spirit of mopars alive, keep up the fantastic work, love that stuff.
All right Nick a 383 I use to have one in a dodge monico big stock double pumper loved the sound of that carb great job Nick keep up the good work brother 💪
Nick you always know how to work your magic when it comes to making horsepower and making torque keep on doing what you doing bro you're the best holla if you hear me
I have a Lunati Voodoo 701 cam in my 383. Awesome cam with smooth idle and 20” of vacuum but man does it rip and I’m running manifolds. They really are nice modern grind cams.
@@lukepokrajac1057 UD Harold quite a story. The even later designs that have ended up at Howards were even better. Comp converted the earlier designs to Automated Grinders as Crane had done when bought the Big Detroit grinder, Comp then sold these now obsolescent. \ designs through their so called tech support. I preferred another way of developing lobes
Back in the Day Mopar lobes were done in the South by a real artist, There was the Clay Smith way, Bill Jenks (Potvin/ Moon way. Ed Winfield ground thecam for our AMCIndy projet. Ed Iskenderian paid up for Winfields intellectual property and Crane also used it Dick Jones developed it and computerized it with much further development. Still the best cam design and selection programs. GM had Jones sons Rik and Mike develop the cams for their Indy project.
Installing the air cleaner just might give you the richness that you’re looking for. A good friend of mine is a veteran Six Pack guy, and I remember him saying the same thing I heard Nick say at the beginning of the video. You always test a Six Pack with the air cleaner installed. 🤷🏻♂️🤔
We did a 6 pack setup (440) a while back where someone decades ago eliminated the secondary vacuum pots and modified the secondary metering plates. I was expecting the absolute worst on the dyno, but it was actually pretty responsive and relatively bog free.
That's why my 68-Road Runner in 67 with 383 with carb work, new distributor, 4.30 rear, headers-straight pipes with resonators only, 4-speed Hurst shifter and more could beat ALL 440's, had some problems with HEMI's if the upgraded. Remember that year 383's had 440 heads.
I had my dream car right outta high school, a 1970 Challenger 440+6. I knew that some of the AAR 340 also came with 6-paks, but I'd NEVER heard of the 6-pak setup being mounted on a 383. Interesting. Great channel, Nick!!
If I remember correctly, Edelbrock made intake manifolds for all three engines, but you are right in that only factory engines that received 6 paks was 340 and 440.
Nick, my 383 build is completed and motor is in my 1970 Road Runner as of last week! Stroked out to 480 cu in, with Holley 750 cfm, new cam, roller tappets, stock manifolds. On the dyno we pulled 425 hp and 530.5 ft lbs! It feels absolutely amazing to drive! Just did some tweaking on the distributor springs to cure some knocking, and it is running great now. I'm a happy man. And all from a 383, amazing.
@@ShannonLandsberger Here's the build sheet of everything major. One thing to know is that there will be some milling to do in the block, in order to get clearances for stroking kit. On my block it took about 6 hours of hand work and testing. My carb is not on the build sheet (?Did they forget to charge me) but it's a 750 Holley. I reused existing manifolds for simplicity and to retain original look of engine. They are pretty free flowing I'm told. With stroking this motor is now a 480 and you can see dyno results above. Chrysler custom kit eagle stroker crank, eagle H beam rods 6.760 icon pistons, moly rings and cleavite bearings Roller cam competition cams Extreme Energy hydraulic xr280hr 23-711-9 roller lifters comp cam Edelbrock intake Comp valve springs 925-16 Comp retainers 10 degree 741-16 Hope this is useful let me know if any questions.
@@ShannonLandsberger Its the Eagle Stroker kit which includes crank, pistons, and rods. We did not do any custom work on the heads. The build was done by Watts Racing Engines in Seabrook NH. I told them what I wanted and they came up with the design specs, ordered everything, and they did everything turn key. They hit it right on the money. Hope this helps, let me know if you have any more questions. :)
When a car is set across the world for you to put your magic touch to it and build the motor that itself speaks volumes about you and your business. Amazing 👏 Nick. Glad you had a good vacation nice to see you back at the shop making videos 📹
The best part of this is not just seeing the results of the dyno testing but also watching two great friends doing something together that they both enjoy.

Hey NICK here's a little tip for that "six pack stumble". Change ONE outboard carb spring in the secondary diaphragm to one range LIGHTER. A lot of guys back in the day would put a stiffer spring in so they came in later; that's wrong thinking. By just changing one spring to one range LIGHTER, that set of barrels opens just a tad quicker. When the velocity picks back up in the manifold, then the other set opens up. That way instead of getting one giant gulp of air all at once and getting a stumble while the motor tries to build up vacuum again to get the flow moving, it comes in more gradual.
Pretty bold thinking Mr. Nick needs a pointer. Pretty bold, man.

A true gearhead doesn't let his pride get in the way he talks to his buddies and gets suggestions. The days of street racing with grudges and top secret combos and unapproachable attitudes is over dramatized kids stuff.

@@mikes.1882There's always a few who like to post an essay to try and flex for the Nick. Desperate for an "atta boy" I guess.
I agree 100% with Mikes1882, in makes perfect sense. This way the engine thinks it has a 4 barrel, then surprise. The extra gas starts feeding the engine when it’s ready for it and the RPM’s are there for it. Too much gas all at once sometimes is not a good thing
Thanks for posting! This brings back memories of my Dad's 383 727 69 Roadrunner. Grocery getter in the family from purchased new that year and sold in 1999 due to his health. He managed to get low 13's out of the car with a min engine mods; Melling cam, Holley carb, a Holeshot converter and 3.91 gears. That engine was a reliable beast. Peace from Boston.
I ran a 68 Galaxy 500 with a 390- 6pack and never ever once properly set had to adjust a carburetor. For over 10 years. Always ran Great ! One of the Best car I ever owned. Always could make you Smile I’d drop the top and listen to that 6-pack , those 3 little Holley carburetor open 1-2-3 . They came in so good. Once there don’t mess with them. 😊
I love to see the school boy enthusiast in Nick. Anybody that loves the technology of these fossil fueled monsters can relate. My favorite was a screaming solid tappet 327 sbc I built for my El Camino. Made 7000 Rpm look like a stroll through downtown. These old engines are a symphony of technology, and an "old salt" like Nick..... the conductor.
Although we are Scandinavian and not Greek, Nick standing there holding his cup of coffee reminds me exactly of my grandfather. He was a skinny little guy too and he just moved like Nick does and he loved tinkering with motors too. He gave me my Tomcat nickname. Love the videos 👍
That has to be the running stroked 383 I've ever seen and what a great combination! A real journeyman mechanic! Well done and great video! Take it up to 6 grand.
I liked that torque curve that I saw at 33 degrees when you first ran the engine. Mine liked 8 initial and I made the advance come in at 2 stages. The initial stage was 2100 with 26 degrees and then the 8 more all in by 3k rpm. Beat emissions standards through 1974 model cars, got 20mpg on the highway, and 0 to 60 mph at 6.2 seconds on a standard 383 with torqueflight and 2.91 gears.
And that was over 50 years ago! Cars made today won't be around in 50 years....(neither will we!)
The design of long rod and offset pins. These big blocks can take 42 degrees total advance with good gas and proper quench clearance
Makes sense to me. You can only swallow so much at one time.
Fifty years ago, an old timer showed me a trick to "fix" the "half dead" carburetor. He crossed two spark plugs which, induced a repetitive crossfire/backfire through the intake upon a "snap acceleration". Carburetor fixed! Whatever was clogging the idle circuit was blown out and settled to the bottom of the float bowl and never came back.
Being from Sydney Australia it just makes me so joyful that a real Road Runner is on our streets I can just feel it's presents sick Niick I love to know where I might see this special car and even hear it
Hello again Nick. Back in 66, my Brother picked up a 61 Plymouth Fury with a 383 Commando, it had dual points from the factory. Another monster!
That is one fine setup. You squeezed a lot of hp and torque out of that 383. I would be proud as hell to run that in that Roadrunner. Theo will be kicking ass and taking names with that setup. Nick, you and Manny make a good team. George, excellent video quality and point of view.
I'm anxious to see what kind of numbers Theo's stroker motor makes on the Dyno. Lets see what the King of Mopar can squeeze out of this engine, here we go!!
Thanks for joining us again, Sir. Here we go!
Hi Eugene how are you mate. Are you getting about in your great 500 ? Steve from New Zealand
@@NicksGarage The numbers didn't disappoint, Theo will have an excellent engine for his for his Convertible RR. It will be a nice cruiser with plenty of power, to destroy the rear tires. I always look forward to Mondays video. Well done George, awesome video!!
@@stevelee5724 Hi Steve, hope everything is going well for you mate. The 500 is still at Nick's but will be back home in Texas soon.
hello Eugene 🇨🇦 👍 👋
I've watched and learnt so much from Nick- I started talking like Nick. My mum asked me something and I said " why it does that I DO NOT KNOW!" Hahaaaa. Hello all from West Australia
Now that is a well built ripper of a Mopar! Properly dialed 3x2's always run SO good on these engines.
You don't often see the 383 or 400 6 BBL's but when you do it's quite a treat!
40+ years ago my Mopar mentor buddy Bob built a 383 6 pack engine for his 70 or 71 convertible Challenger, what a spectacular car and engine.
I don't remember the h.p. number but it was easily over 450+!👍
The convertible Challenger was a factory 318 car that was at a repair station around the corner from Bob's house. He drove by it and stopped in the shop to ask his buddy who owned the shop what the story was about the car. The engine was blown and the owner of it didn't want to fix it, so my buddy asked to buy it and the shop owner said he'd talk to the car owner.
A few days went by and when Bob went by the shop again the car was gone.
He went in to see what happened to it and discovered one of the mechanics who didn't know the shop owner was going to sell the car to Bob had sent it to the junkyard!😮 He burned rubber flying to the junkyard to hopefully save it!
Luckily he was also friends with the yard owner and asked if he knew where the car was.
Sure he said, aisle blah blah over there. Mind you this in in the late 70's so these cars were no big deal then.
As he walked down the rows he wasn't seeing the car.
He again asked the owner where it was,he couldn't find it.
The yard owner said I know it's there, I just put it up there. Up there,up where? Well he wasn't looking up,it was on the top of three crushed cars!😲 Ahhh!!!
Congratulations, You just gave me endless nightmares.
Enjoy watching Nick tinkering with old muscle car engines. Nick and I are about the same age and are both MOPAR nuts! God bless you Nick turning the clock back to our youthful times!
Nick, it saddens me to see any 383 ever again after Selling my 71' cuda. I thought 🤔 watching your channel it would put me in the Mopar Spirit, but instead reminds me of something I lost forever. Best Wishes Cuda guy.
We're sorry to hear that, Gerald. Hope you find that same feeling again, even if the car is gone.
@@NicksGarage thanks Nick you can only imagine selling you Kowaski Challenger. Once I was sent to Indiana. I drove to the Mopar dealership to order the Chrome tips for the Cuda. I drove my wife's Renault they was $100 each. They looked at me & laughed like I didn't have a 383 at home. It took sometime but I think direct connection or somehow they got their asses chewed because when I drove up in the Orange 🧡🍊 Big Block their faces 👀👀 was blank. They couldn't believe I drove it from down South to Indiana. I even went with my buddy Roadrunner Dude to the Mopar Nationals which was held that year Inside The Indianapolis 500 track. I bought a pistol grip shifter. The guy I bought it from removed the column shift & used a cutting torch to cut the floor boards to put a 4 SPD in it. It was purchased new in a town called Alice but a Automatic, he worked as a mechanic so he just changed transmission. It was a Original 383 Billboards & all but missing the Chrome tips. My dad had lung cancer later we found out. That damn Cuda wouldn't start for nothing We Trouble hunted down everything, then ROADRUNNER DUDE SAYS, did you check the VOLTAGE ⚡ REGULATOR!!!! My Dad was going to die & that $10 VOLTAGE REGULATOR STOPPED the Entire Engine From Running!!! Out of Rage I sold the damn thing. We replaced that $10 part on the driver's side engine Compartment & that 383 started up like lightning ⚡. I didn't drive to the Mopar Nationals I Rode Sidekick Instead in his ROADRUNNER. Car Love Lost in Time. Sometimes I think 🤔 the crap I get into could fill a season of THE TWILIGHT ZONE! Look you know about that little metal box in the Driver's engine Compartment. My one Chance for Two 383s to go together inside the grassy part of the Speedway. Sad but True. I couldn't make this stuff up. Still Love Cudas. One day down here I heard a large engine approaching, it was a 71' ROADRUNNER 440 SUX PACK . YELLOW & BLACK .
It just goes to show that even Nick, with over 50 years of engine building experience, can still get nervous and flustered. A consummate professional.
Only human!
@@NicksGarage Dr. Nick is more then human. lol
To be fair... All engine builders feel a bit of pressure on a first start... On a first turn over... And for break-ins
Extra- excellent music during the intro George! I'm always listening!!
Glad you enjoy it! Music choice can be very polarizing.
Thank you Manny and Nick!
Paul (in MA)
I had a friend back in high school in the 70`s that had a `70 Challenger R/T 383 4 speed. That car was nuts, man was it fast. Good times, it was a tire melter too, but not a six pack. I love dyno day! Here we go!
Thanks Nick for your hospitality Friday when I visited your shop.
Thanks for showing me around and I enjoyed talking about cars, engines and the challenges of operating a shop.
All the best .
Hope to visit agin in the future
Thanks again.
It was my pleasure. Come anytime again.
Manny ,love the " Quality Control " comments at the end .. That Engine is going to be a screamer in that Road Runner !!!!
426 hp from 433 cubic inches, 485+ pounds of torque with the air cleaner on, with a smooth idle and very good vacuum. Not to mention its got cast iron factory heads. This is the engine you should make for everybody from this point on. This is going to be a tremendous street engine. Does anybody make reproduction cast iron exhausts from a Stage 3 Ramcharger wedge.? If not, then the best cast iron exhausts from the exhaust manifold test you made last year would be a nice second. Nick, whoever suggested to you to test a 6-barrel engine with the factory air cleaner on, he gave you a nugget of wisdom.
Nick a friends 383 we raced in a 70 Road Runner. 850 Holly with 90 jets. 1" spacer. Timing at 38⁰. Motor was balanced and bluprinted. Steel heads, big valves. Hydraulic tappets. Purple shaft cam. Forged pistons. Can't remember the rods? 6 pk rods maybe. Ran 11.8 on regular gas at first with led additive. It would rev to 6000rpm no problem. Standard crank, +40 bore. When the engine builder dynod it the dyno messed up and reved to nearly 8000 rpm lol. The noise was incredible!!! 😁 520 bhp and 640 torque! Eventually we tried a 150 Nos kit and got 10.2 on a quarter. Changed the cam for a custom grind. Little monster the 383!! Road Runner was stripped interior and two race seats and a roll cage.
You guys work well together - and the conversation adds interest and understanding.
The three deuces was a fun piece of performance bling, actually useful for only a short period till the real high performance 4 barrel carburetors came out.
I like the down the carburetors view as the engine runs ! Not always a safe place to have your face...
Dr. Nick, Theo's motor sounds awesome!, thank's for the extra long video, good work Manny, and George, cheers
Great video guy's! Bill from Linglestown, Pennsylvania
Raise the fuel level in the float bowls a couple flats on the adjusters to richen the mixture a bit. Saves the work on removing the carbs.
Awesome work Nick, that fellow in
Australia will be giving Mad Max
a run for his money, he will definitely
run down the Toe Cutter LOL!!!
Good evening to all! Watching those carbs in action is really awesome. Great video again and congratulations.
Goooood evening, gents!!!!! Man, I looove watching these dyno videos, seeing Nick scratching and clawing for every ounce of power he can get!!!! That’s a pretty good and quite interesting combination of the 383 bore with the 440 stroke: it would be VERY INTERESTING to see the results with a bigger cam and some semi-serious heads: I’d like to build that combo myself lol!!!! Nick and Manny make a great team, and George, your video production skills showcase everything perfectly: great week to you guys!!!!!
He's an old school artist! I've seen so many newer style engines, with fuel infection, electronic ignition, and "power adders", on the dyno on other channels, and their tuning is done with a keyboard. This is so much more involved, having to change jets, adjust timing with the distributor, etc. He's truly the Mopar Wizard!
Hi Nick, Manny & George great video guy's. If Theo not happy you can send it to my daughter for her AP6 Valiant she just shouted, kidding I hope Nick as that is one beaut rebuild with some nice numbers too. Thanks all and stay well till next time.
That engine is making incredible power for such a mild streetable cam,a lot of power and pleasurable to drive, very nice job MrNick
My ex father in-law graduated high school in 1969, and he bought a '69 Super Bee and a '69 Harley-Davidson Sportster. As he put it, the Super Bee "only" had the 383 motor, and he sold it in the 70s when gas prices skyrocketed. He still has the Sportster that he turned into an "Easy Rider" style chopper (complete with a hardtail, long forks, high bars, sissy bar, and purple metal flake paint with pinstripes) but he wished he has his old Bee, too!
I had a 1970 413 police interceptor motor, in a 1972 D100 Stepside. God I love that truck the most reliable thing I've ever had in my life, and it was the wedge motor, made tons of power. Just about gave it away, I'm so stupid.
Hey Nick, I just subscribed! I’ve been watching for a few years and love your videos. I like what your did with the 383 stroker. It’s nice to see something different. Last year I built a 400 that was not a stroker motor. I love the idea of the large bore and the short stroke of the 400. I put a 383 steel crank in it. I feel the 383 and 440 gets all the attention and the 400 doesn’t interest people other than for stroker motors. After my build I put it on a Dyno and made 457 hp and 463 torque. Used 906 heads, hyd flat tappet cam and runs on 91 octane. There are many 400’s out there cheap and can make big power when built properly. It would be nice to see something out of the ordinary in your videos like what I did. I’m sure lots of viewers would be entertained seeing something like that. Thank you and keep up the good work! Jake P, Minnesota
Thanks for your subscription!
At what RPM?
Nice job on the engine. I love it when the horsepower matches the displacement.
I enjoy watching you in your beautiful shop. I'm very impressed with your engine building skills. It's very obvious that you've been around the block a few times. I really like the ways you diagnose every problem! Thanks for your channel.
Great video as always impressive work. I like that Nick wants to get the most out of every engine he builds or works on.
That centre carb isn't putting out the fuel the other outboard carbs are which might be the cause of the lean mixture at high RPM but damn that engine sounds good.
I keep seeing the same thing. Nick should watch the overhead view, he'd probably see it too.
I'm thinking what you're seeing is without the air cleaner on. This is one of the thing's I'm curious of about those three two bbl setups though. Those Chrysler air cleaners are really low profile
The end carbs do have idle mixture adjustment screws. The factory carbs had them hidden behind plugs that were easily knocked out. Keep up the great videos much enjoy!
383 that made Chrysler what it is today.....Amazing engine build by Nick Congrats my friend👍👀....Thanks Nick & Manny.....Shoe🇺🇸
Evenin Mr Nick!! Have a Great Week!! Glad you're back in the Dyno room!!
That engine sounds so smooth. You are a real master with that 6 bbl set up
I think you hit on the right combination even though you thought the cam may be wrong . It worked out very well .Congrats !
Bon Jour/ Good Day. I have always like the shots of looking down the throats of a six pack.
You and me both!
@@NicksGarage Uncle Tony's Garage put up a video yesterday about a bunch of Mopar parts he had just acquired, it might be worth your while to look at it.
@@derekbowbrick6233 ... Thank you.
Its midnight and I couldn't leave until you made your final run. Thanks Nick.
Welcome back, Nick!
Thanks for being here.
Nice build Nick great numbers! its always great to see you and Manny working things out together. Almost the same numbers as my 440 bbl. Another excellent video George!
When I would build a engine.. I always tuned it with a vacume gage and timing light..I got to where I hardly used a light!!Great upload!!Thanks
That is one great engine build! I sure enjoy the dyno episodes......Thanks Mr. Nick 🤗
Nick, you are like me I don't say how good everything is to the end so I don't jinx it. I couldn't help but hear every time Manny wanted to say something positive about the build during break in you kept saying "we'll see."
The way I see it ..nick likes to think alone at times..times you working best by your self..
Tell me if I'm wrong but the reason those air cleaner base plates are so big- they come right out to the rocker covers- is to trap the hot air coming off the engine so it doesn't go into the carbs. And it's angled to feed hot air out the back. Great design.
If anything it traps the air under it and heats up the carbs , same issue wit hthe single 4 bbl base and the Hemi dual quad base .
@@dartgts383 yeah maybe.
@@dartgts383 I just remember when Nicks brother put just the base plate on his hemi race engine, from memory, it picked up some horsepower over not having it. So it is doing something.
@@dartgts383 another good thing is you can actually tighten down just the base plate cos they've got those bars going over the carbs. Most air cleaners you have to put the whole filter and top plate on to tighten them down. So mopar really thought of everything.
@@dartgts383 but thanks fr replying because I'm wondering what other people think.
Hey Nick,George, and Manny , was out of the loop for a bit . Love watching Nick & Manny working in the dyno room . George love those light colors in the dyno room too . You do great work with them .I pickup some of your lighting ideas and use in my shop ...
I will say your one of the best mopar guy I've ever seen.they may be people as good ..but there not better.
Brought to you straight from the 450! 383 are strong runners!
A stout engine, for sure.
The horse power on my 69, road runner,383dualquad, factory in line,off a58plymouth,, with a little bit of modifying, pulled 460horses, and 510torque, and turned the eight mile in six seconds on the right rear tire going flat,had to let off the pedal about about a hundred feet from the light.
very good video, I'm watching here from Brazil
Thanks for watching!
Incredible! The 383 didn’t always demand respect, goes to show simplicity rules…This will turn heads. HP, Smooth and tons of tire shredding Power. Well done Nick. Thank You Manny and George. Brotherly Love from Deep South Texas, Lee.
6 packs are so fun to get set my dad did a lot of swearing at them till he got it.
Haha. That seems to work sometimes.
I hear a lot would just thrownthem in the trunk.
If you're just one or two percent short of your number, try running the oil a quart low. The engine isn't being subjected to launch, cornering, and braking, so, no harm should result.
I used to work on a Pro Stock team, and one or two thousandths of a second can be the difference between making the next round or loading up the trailer. We used nine-quart pans with four quarts in them, along with some very sophisticated windage trays, to keep the oil away from the crank.
When we had a "street" engine on the dyno, we would always run it a quart (or two!) low. That was usually good for four to five percent.
You know something, the work,passion heart and expertise you put into an engine buld is worth every penny you are paid😎💪
Right on nick sounds real good so glad you kept it B-BLOCK
Thanks for watching, Darren.
Another beast from Nick’s Garage
Right on!
Love this! My old man drove a red 1966 coronet 440 model, 383 4 speed, when he was in highschool mid 70s era, people around him said that car could hurt some bb chevy feelings. Those sounded like the good days👍
BACK IN the Viet Nam Days my friend came back and purchased a charger 440 4v 4sp it kinda smoked my brothers 442 olds 1970 model
A fair weather car with that kind of an air cleaner that's for sure stock is good and wet weather all day
Definitely a stroker build in my future - just awesome!

Nice to have a friend like Manny
Awesome car and engine another good one keep them coming and see you Friday
My father, when I was younger, ( now65) got hold to a set of heads from a company that cast them in a HEMI configuration, the relocated the valve angles to work on the (B) ? Block 383 and 440 short blocks so that you would have, basically a high reving torque monster HEMI, that thing, coupled to a TCI 727 Automatic, with a custom torgue converter could destroy a set of Firestone drag 500 slicks at the drag strip back in the 70's and 80''s he won many events, my father, (God rest his soul) was one of the innovators back in the day he had one heck of a reaction time and would smoke so many of those other drivers coming off the line, it was ridiculous and glorious at the same time, gave me the love of all things mechanical, I miss him he was a character and had a very odd sense of humor and could find, even when he lost a race, something funny in the moment, Nick is in that same group, keeping the spirit of mopars alive, keep up the fantastic work, love that stuff.
Love all the lighting y'all been adding, really set's off the video footage
Master mopar engine builder! Every one is A sweet gem!
All right Nick a 383 I use to have one in a dodge monico big stock double pumper loved the sound of that carb great job Nick keep up the good work brother 💪
Nick you always know how to work your magic when it comes to making horsepower and making torque keep on doing what you doing bro you're the best holla if you hear me
I have a Lunati Voodoo 701 cam in my 383. Awesome cam with smooth idle and 20” of vacuum but man does it rip and I’m running manifolds. They really are nice modern grind cams.
Great Choice Same designer but later design than Comp which was still using SBC profiles on MOPARS
@@jmflournoy386 yep! Harold Brookshire design.
@@lukepokrajac1057 UD Harold quite a story. The even later designs that have ended up at Howards were even better. Comp converted the earlier designs to Automated Grinders as Crane had done when bought the Big Detroit grinder, Comp then sold these now obsolescent. \ designs through their so called tech support. I preferred another way of developing lobes
Back in the Day Mopar lobes were done in the South by a real artist, There was the Clay Smith way, Bill Jenks (Potvin/ Moon way. Ed Winfield ground thecam for our AMCIndy projet. Ed Iskenderian paid up for Winfields intellectual property and Crane also used it Dick Jones developed it and computerized it with much further development. Still the best cam design and selection programs. GM had Jones sons Rik and Mike develop the cams for their Indy project.
@@jmflournoy386 wow interesting!!! The only bad thing I can say about the voodoo is it is a little noisy when aluminum heads warm up
George...you had us in stitches with the timing hammer. I Had to pause the video because I laughed so much.😝😝
Installing the air cleaner just might give you the richness that you’re looking for. A good friend of mine is a veteran Six Pack guy, and I remember him saying the same thing I heard Nick say at the beginning of the video. You always test a Six Pack with the air cleaner installed. 🤷🏻♂️🤔
Wow!!! great video my brain is like a sponge watching you work
I'm waiting for Nick to do a complete cylinder head porting video. THAT would be a good one!
Man fellows,she looks and sounds strong,Great build guys...
Great job guys. Wonderful to see Manny, what an amazing team !!
We did a 6 pack setup (440) a while back where someone decades ago eliminated the secondary vacuum pots and modified the secondary metering plates. I was expecting the absolute worst on the dyno, but it was actually pretty responsive and relatively bog free.
👍Lotta power in that 383! Great video! Thx Nick and crew!
Our pleasure!
Hey Nick I had a 383 in my 69 Road Runner.✊😁
Great engine the 383.
That's why my 68-Road Runner in 67 with 383 with carb work, new distributor, 4.30 rear, headers-straight pipes with resonators only, 4-speed Hurst shifter and more could beat ALL 440's, had some problems with HEMI's if the upgraded. Remember that year 383's had 440 heads.
I had my dream car right outta high school, a 1970 Challenger 440+6. I knew that some of the AAR 340 also came with 6-paks, but I'd NEVER heard of the 6-pak setup being mounted on a 383. Interesting. Great channel, Nick!!
Yeah I believe the 440 and the 340 are the only 2 engines that ever got that carb setup. Fun fact they used the same carbs on both engines
If I remember correctly, Edelbrock made intake manifolds for all three engines, but you are right in that only factory engines that received 6 paks was 340 and 440.
Same here, you can get after market intakes, but never heard of one from the factory with 3 deus. I’d like to know more!
Nick, my 383 build is completed and motor is in my 1970 Road Runner as of last week! Stroked out to 480 cu in, with Holley 750 cfm, new cam, roller tappets, stock manifolds. On the dyno we pulled 425 hp and 530.5 ft lbs! It feels absolutely amazing to drive! Just did some tweaking on the distributor springs to cure some knocking, and it is running great now. I'm a happy man. And all from a 383, amazing.
I have been looking at a 383-496 stroker kit for mine. This makes me think it might be the right move. Do you have any more info on your build?
@@ShannonLandsberger I just got the build sheet today and will share the details with you tomorrow on the stroke kit, cam, etc. Stay tuned!
@@ShannonLandsberger Here's the build sheet of everything major. One thing to know is that there will be some milling to do in the block, in order to get clearances for stroking kit. On my block it took about 6 hours of hand work and testing. My carb is not on the build sheet (?Did they forget to charge me) but it's a 750 Holley. I reused existing manifolds for simplicity and to retain original look of engine. They are pretty free flowing I'm told. With stroking this motor is now a 480 and you can see dyno results above.

@@richardbornemann806 Was this a stroker kit from someplace or your own selections? Did you do your own clearancing and build?
@@ShannonLandsberger Its the Eagle Stroker kit which includes crank, pistons, and rods. We did not do any custom work on the heads. The build was done by Watts Racing Engines in Seabrook NH. I told them what I wanted and they came up with the design specs, ordered everything, and they did everything turn key. They hit it right on the money. Hope this helps, let me know if you have any more questions. :)
Loved that motor. I put one in my 59 sports furry with dual quads. Bought lots of tires
When a car is set across the world for you to put your magic touch to it and build the motor that itself speaks volumes about you and your business. Amazing 👏 Nick. Glad you had a good vacation nice to see you back at the shop making videos 📹
Nick and Manny. Another great build. Nice work and thanks for sharing!
