It didn't get burned, so that's where it is. Standard practice is to automatically change the oil. Aside from washing down the cylinder walls, there's real danger of an explosion.
Dear Mr. Nick, I thought I would comment since I was told my name was mentioned in this video. First off, this 572 Hemi ran like a Rolex when my partner first built and tested back in late Dec. 2020. The engines original owner wanted the look of dual in-line Holley's that would be easy to start and drive to Tim's and C&C, hence the reason why I built (& tuned) the twin Holley 600's.With 10.6 comp ratio and 205 psi cranking it ws a great match for pump 91. This engine idled at 1,050 rpm with 17" hg, and approx. 13.8 AFR, made a very respectable 724 TQ and 735 HP with about a 12.7' ish AFR with pump non Ethanol fuel, it was actually pretty good on fuel, a testament to the machining & build quality. But, after months and years of the engine sitting and not really being used, pump fuel with Ethanol takes it's toll on any carb, be it zinc or aluminum, just not Holley's LOL. I had to "visit" the shop to "clean & fix" the new carbs due to corrosion/varnish that can bugger up a Holley or any carb real quick. I have no idea why the distributer was removed and installed 180 off ? I guess the carbs could of (should of) used a rebuild. If you have any Holley's you are tossing away because they are older than 3 years, please let me know, I'll drive to your shop and be glad to take them off your hands, I'm serious on that. By the way, it's a solid roller.
I thought it was common sense to flush out E85 and fuel using ethanol with non ethanol fuel when a engine will not be in use. I guess common sense is not too common anymore. I run 110 through my carbs before it sits for the winter or even for a few weeks. I thought everyone knew that ethanol fuel is not good to let sit in carbs.
@@79tazman To be fair, there was 91 pump non Ethanol available everywhere at the time of this build (Dec. 2020) and the reason why we used it. 91 pump, non E was available for a few years afterwards. But, like I mentioned, I had to service the carbs a year or so later because they just sat and fuel evaporated, it takes a toll, even non Ethanol. My car can sit a moth or 2 with Ethanol, but longer than that, it get's drained and cleaned out. The race car stuff I work on, the carbs get drained after every race!!
@@mperuski100 exactly me too, pretty basic thing to check, never trust anything thats gone before start at the base and work through it before starting
This is one of the best episodes ever!! Great for viewers that love to learn. Can't wait for follow up video. I'd also check the oil for gas. All that gas went somewhere.
The typical drawback of a carburator on a highly cammed engine, you have to open the primary throttle blades quite a bit to allow more air into the engine to get it to idle decently. For those that do not know, that will expose more of the idle transfer slot than it needs to be, usually .040 max opening. When that happens, its allowing more fuel into the engine and the idle mixture screw adjustment becomes inaffective. The fix is to open the secondary throttle blades just enough to get the primary throttle blades back into adjustment, then your idle mixture screws will become effective once again, its a wee bit tricky, but it can be done.
I can't believe how much you assumed things were right after finding the first two errors! I would have questioned the cam and timing areas, that's the only thing that will shoot sparks out the carbs and the exhausts! Sparkles going to the wrong cylinder and/or at the wrong time! And then the 2nd time you eyeball the distro you see it is 180 out.....omg! They could have changed that distro BEFORE it went to storage.....we weren't there, therefore we DON'T know. Can't count how many times I've had an engine sitting for year, outdoors even, and both fuel and carb accelerator pumps had dried out diaphragms. Dump some fuel in the output side of fuel pump and in the accel pumps and literally about18 out of 20 would awaken and work fine.
What was a disappointment for me was watching Nick manually checking accel pumps, stating they are bad and not working, but going in to the dyno and pumping that throttle handle multiple times before cranking. What were you thinking Nick, you knew the pumps were not working.
@@robt3305 worse yet, one of the times he said both pumps were not working, he is looking down into the carbs and when he hit the plunger on the front carb I can clearly see it squirting fuel. No worries, I still love the guy lol.

It is probably too late for this due to editing time but I would definitely change the oil before restarting. That much over fueling probably added a fair amount of gas into the oil.

That's the right way to do it.

If dry sump arrange oil tank etc with clients, whether there are lifting points to speed the setting up, etc. Expected peak power/rpm/torque and rpm it's to be taken from, etc. in case it exceeds the capabilities of the dyno', or it has to be set up for it.

I would do an oil change as well. 4 cylinders of unburned fuel has guaranteed washed past the rings and contaminated the oil. Probably more than a gallon of fuel in the oil pan.
I did the 180-degree goof on my '65 Coronet 383-4V many years ago when I put in a Mallory dual-point distributor (Model No. 2557701; I have NO idea why I can still remember that 40-plus years later!). Not difficult to do.
It's been sitting for three years says everything, never even fired up in three years, everything dries up , specially those big ass carbs , street bikes , motorcycles do the same thing everything dries up, hoses ,fuel lines, my sons Honda sat for five years and I knew , so we just replaced everything , a 572 hemi that's a monster I love it , Nick will do his magic and I can't wait to see it when he's done
Lolololol spit my coffee out when Mr.Nick let a few words fly !!!! Plus seeing George duck when that Hemi fired for Effect !!! Great reflexes George and Nick !!!!
Replacing a few gaskets & O-rings in the carbs and installing the distributor correctly is no big deal, especially if that beautiful motor was bought for a good price. The buyer should have been aware that it needed some investigation and care after he got it. How many people buy an engine that is complete, tuned, and ready to install as they get it?
Very cool to see Mr Nick abd his Brother working together . Love when we get into the trouble shooting , working getting things to come together and fire that big Hemi off !!!!
Nick looked worried right at the beginning of the vid. I'm really surprised he did not do what he usually does if he did not build the engine. She gets a solid once over. Fantastic video guys!
I like the back shoulder mechanics chiming in. This is what really frustrates the first start of any rebuild. But also what makes us tick. Solving the problems along the the way and reaping the rewards of just being around friends while you solve it. This is the scene I miss the most from my youth. The crowd that used to be. Is now just a few. But still exciting none the less. Thanks Nick for the tag along.

Good afternoon Nick & George, Wow, a 572 Hemi on the Dyno!! This engine appears to have multiple issues, but Nick will figure them out. I'm anxious to see if this will make the claimed 750 HP. Nothing better than a Hemi on a Monday afternoon at Nick's Garage. I hope that you guys have a great week. Here We Go!
@@NicksGarage I really enjoyed the video George, the music was awesome, and the camera angles were perfect. If it was my engine I would put on a pair of Carter Competition Series750 cfm carbs. Waiting for part 2 or 3 to see the final numbers.
Hello Eugene, How are you enjoying your beautiful Charger that Dr. Nick completely rebuilt for you a few years ago? You must be loving it on the beautiful Texas roads!
Need to get a SpinTron to test engines, like this especially before starting, it will turn motor over usually up to 500 rpm and allow you to get a wide variety of information before actually firing it up
Great to see you and brother working together! Didn’t see anything about checking to see how washed down oil was, I’m sure it was diluted. I’m sure Nick you will get this beast running great again!
Im right with nick, im 64 and spent many years rebulding carbs & I grew to hate Holleys with a passion brand new ones were almost never plug and play jet changes and float bowls gasket upgrades from the old cork were the norm, they nearly always seemed problematic and needed endless tweaking and tinkering --- worst of all is that they STILL use that dam power valve thats toast after one good backfire, that doesnt happen with other carbs except maybe a ford autollie, also a holley design -- I always did great with a quadrajet, a carter or similar the Edelbrock four barrels.
The carbs have a check valve in the throttle plate to protect the power valve from backfire. Even before Holley put in the protection it was highly exaggerated.
I have a 572 BBC with lots of extras I run 108 octane fuel …. Nick did you measure the vacuum and put in the right size power valves ? Just asking I’m sure you did and I hate 600 Holleys ….🇺🇸👊🏼👊🏼✌🏼 Great video and yes that engine really chugs
I agree with Nick. Take the existing manifold and carbs off. Install a proven carb and manifold on and see if the engine is good and will perform. Change the oil and filter, the gas went somewhere. Cut the filter apart and inspect for metal and contamination. Thanks for sharing. 👍 Have a great day.
Het Phil!.. I always enjoy seeing you on these videos.. You remind me of a fellow I once knew.. he had two PHD's and was smart as a whip. he was a good friend.. I miss him.. They sell things on facebook.. I just thought it was a place for juveniles to go and spit at the world and each other.. at 73 I never even thought about it, though my brothers and sisters are on it.. Maybe I will give it another think.. What a shame about the engine I was a Holley fan in my younger years but after sitting like that they do need complete tear down and cleaning.. Thanks guys I love these trouble shooting videos.. Plus the tear down vid's
Back to basics…..check timing, spark plugs and fuel delivery…….never trust anyone but yourself! Good video as to what happens when you skip these basics!
With 4 cylinders not firing right, lots of un-burned fuel will come out the exhaust and show a rich reading on the O2 sensors. That’s the problem I would investigate first. Am I missing something ?? In my opinion, it’s not a carburetor issue.
I never take for granted that people tell the truth or know what they are talking about. Obviously it was 180 out at the first backfire! After that i would check over everything and assume everything is a mystery
Shocked you guys didn't realize 180° right away? Excellent channel 👍 Thank you I do a lot of reverse rotation marine engine and see this alot Air idle bleed emulsion tubes get clogged gummed up alot on Holley flood o matics . Cause rich idle .
I would probably drop oil & filter on it because the oil is full of undurned fuel & the last thing you need is ring wash because of all the fuel washing the oil off of the rings and cylinder walls . I remember watching that episode with that Ford that was in the trailer that sat & you were having a heck of a time trying to get it to run to get it in the shop last winter because those carbs sat with old fuel that basically destroyed them from sitting . You hit the nail on the head on the problem and its a very good idea to stop & swap the intake manifold & go to the big single 4 barrel to get it running right to find out how well it runs and make some pulls just to see how close the power numbers are . Another great video from Nicks Garage !
Rule#1: people will lie to you. It should be obvious by this time that it wasn’t put away running. I had that same problem with my first engine, but I was 16. 180 degrees out.
Check for a firing order swap cam. I suspect someone swaped out the dist. In storage And timed it 18436572, or it came from a swapped order motor. The only way for a 18436572 motor to run that even on 4 cylinders is if the end cyls on one side and the center two on the other are not working. That's not what you have going on. Could be wrong, tho. Anytime you have a dead cyl upstream of an O2 sensor, it will read rich even if you lean it out until it dies. Also, if it has a flat tappet cam, was it broken in correctly? I'm not familiar enough with them but it seems like a good high compression new 572 would work that starter harder? Also, it may be a trick of the camera but the rear carb seems to have much smaller venturies than the front carb. Good luck, Nick!
The accel pumps are delivering enough fuel to start the motor. After the first carb backfires it was obvious the ign timing was off quite a bit. Floats stuck. Carbs are all gummed up.
Timing Timing Timing ‘. I had 2 #1’s on my Distributor Cap on my 383 after Rebuild and Obviously we tried to start it and i was standing over top the carb and Boom 💥 my hair was on Fire and my Eyebrows and Eyelashes burned 😂
My experience with those 600 vac sec Holleys is that they run great new out of the box, but once they need a rebuild, sell them at the local swap meet. You will never, and I mean _never_ get them to run right again no matter who installs the kit and adjusts them. I don't have that problem on the 4150 based carbs, just the flat bowl transfer tube 1850 based units.
I've been enjoying watching you bring this beast to life Nick I'm kind of surprised at the buyer bought this not knowing anything about what was in it whether the lifters were solid or hydraulic? And as you discovered it wasn't even run before it was put up for sale But once it's running that idle it sure sounds like a beast And how would you know what the lifters are without pulling off the intake manifold? And then if they are solid what's the intake and exhaust clearances? Other than that it's been another enjoyable video life and thank you !
That motor wasn’t ready for the dyno. You can’t expect something with carburetors that has sat for 3+ years to just work. That guy should have had the carbs gone through before it ever came through the door.
First crank at 6:55 fuel is going past the needle&seat on the rear carb already. Most of the fuel is in the oil now. Love the channel Nick, but man you gotta run the pump for a while and check that before trying to start it, especially after seeing the rock hard pump diaphragms.
Yes from the top view you can see it was pouring gas in there. Some gasket is leaking or the floats were stuck. Maybe you could set up a monitor to see that view while you are working the throttle at the dyno.
I'd suspect both power valve diaphragms are dried out as well as stuck or dried out acc pump diaphragms. Could be adding fuel through bad power valves , sounds overly rich beyond jetting or idles adjustments . Nick will find out what's what though .
Dana "60" Glass. I remember one engine you had on the dyno that gave you fits. The '70 Boss 302 motor. There were a few others that were frustrating, but the Boss stood out. I knew you would get the big HEMI figured out. With properly adjusted carburetors, this monster should get at least 700 hp or better.
Check the pin on the cam side gear,had a 79 351 Windsor motor that would run great but when it backfired,I had to pull out the distributor and rotate it 180 degrees for it to run again, the pin that holds the gear ⚙️ on the shaft was sheared but it always spun 180 degrees
I learned a long time ago that when in this situation, start with the basic fundamentals. Check the timing and firing order as the first step. It only takes 10-15 minutes. Then check for spark. Then check for fuel. You'll save tons of time this way. I had a 440 Blues Brother replica a guy couldn't get running. It turned out the firing order was "correct", except that he wired it in the wrong direction.
Looks like the check valves in the accelerator pumps are stuck closed. A shot of chemtool down the passage will usually loosen them up nicely. Great engine! I personally think that it's acting like it's 180 degrees out at the distributor, or someone did the sparkplug wires backwards(clockwise in stead of counterclockwise, seen it before).
Looking forward to seeing the big Hemi running good and making a pull. You can’t trust anyone. That much fire had to be timing way off. Thanks for the Videos, Nick. Hopefully you got a good deal Gatan.
Hello Nick. Awesome video as usual. Did you ever get the old 354 Hemi done and dyno tested? I'm going to build a 392 for my '33 Dodge coupe and I'm dying to see some kind of dyno test on a Gen 1 Hemi. They are amazingly rare. I can't find any decent ones on RUclips except wild race engines. There are a couple of old magazine builds but I'd really like to see you do one. Thanks.
A spark plug with a 3/8" and 7/16" UNC bolt welded perpendicular to the hex portion of the body gives you a quick tester plug that threads into the front of most engine's cylinder head as a ground, hook the coil lead to the plug and just crank the engine. An AC volt meter across the leads of a mag pickup MSD distributor when cranking should produce a small voltage when cranking. We have a variety of spark plug leads, bulkhead fittings and whatnot to adapt any coil to any lead or distributor cap.
5:40 no need to remove the carbs, just pull the accel squirter off and stick a thin pick down the threaded hole to work loose the stuck anti drain needle that resides below the screw. EZ PZ.
When I saw flames out the exhaust and intake I knew it was 180 off
I agree...

I did the 180-degree goof on my '65 Coronet 383-4V many years ago when I put in a Mallory dual-point distributor (Model No. 2557701; I have NO idea why I can still remember that 40-plus years later!). Not difficult to do.
Great episode... The intrigue and added detective work only added to the entertainment!
It's been sitting for three years says everything, never even fired up in three years, everything dries up , specially those big ass carbs , street bikes , motorcycles do the same thing everything dries up, hoses ,fuel lines, my sons Honda sat for five years and I knew , so we just replaced everything , a 572 hemi that's a monster I love it , Nick will do his magic and I can't wait to see it when he's done
Lolololol spit my coffee out when Mr.Nick let a few words fly !!!! Plus seeing George duck when that Hemi fired for Effect !!! Great reflexes George and Nick !!!!
Glad you enjoyed it. haha
FAFO said Nick
Yeah I really felt that. Nick doesn't usually swear but when he does it's warranted. It's what I've been doing,,,,
@@NicksGarage I did George !!! Laughing with you . I would been moving too .Best Regards to yall .
Moral to the story, don't buy an engine off Facebook.
Why? it needs the carbs rebuilt.... that's it....
I’d definitely recommend changing the oil and filter to get rid of the contaminants in the oil that’s in the engine now.
love anything mechanical, but especially something mechanical that has some serious Horsepower, great video's Nick.
Couldn't agree more! Thanks for watching.
Spit shined the carbs on the outside & neglected the internals that make it actually perform.
buyer beware
wrong again
Replacing a few gaskets & O-rings in the carbs and installing the distributor correctly is no big deal, especially if that beautiful motor was bought for a good price. The buyer should have been aware that it needed some investigation and care after he got it. How many people buy an engine that is complete, tuned, and ready to install as they get it?
Very cool to see Mr Nick abd his Brother working together . Love when we get into the trouble shooting , working getting things to come together and fire that big Hemi off !!!!
Thanks Sarge. Great to see you.
@@NicksGarageAlways great to be seen too George!!!! Always good to hangout with yall .
Nick looked worried right at the beginning of the vid. I'm really surprised he did not do what he usually does if he did not build the engine. She gets a solid once over. Fantastic video guys!
"It was running" hahaha. Remember the famous words from Animal House: YOU F**KED UP, YOU TRUSTED US
I like the back shoulder mechanics chiming in. This is what really frustrates the first start of any rebuild. But also what makes us tick. Solving the problems along the the way and reaping the rewards of just being around friends while you solve it. This is the scene I miss the most from my youth. The crowd that used to be. Is now just a few. But still exciting none the less. Thanks Nick for the tag along.
I come here to nicks garage to learn and enjoy car stuff, I read comments and really feel like the world is filled with know it alls , who know little, so easy from your keyboards , get your own successful channel, see the comments fly on your work..
Thanks
@@NicksGarage mr nick you inspired me for years , you wrote me once about my question out my Dakota. .5,9. Rt. and you personally answered and I will always remember that , I truly enjoy your channel so much .
Before tearing the intake off, Nick, try changing the O-rings on the needle & seats. I'm confident that they are dried up causing your rich and flooding problem.
Nick changed those earlier in the video.
@@moparmike2535 he kept calling the rear one the float he changed. he changed the level but not the float item... i did see one needle and seat he changed in the rear but not the front,...
NICK, YOU ARE THE COOLEST MECHANIC EVER!!! I love 💕 all of your builds and especially your stories or tales from your glorious engine 🚂 builder past. Your wisdom and expertise is appreciated by the Hot Rod fans! Keep up the good work 👍😁. Great video 📸. Thanks.
Good afternoon Nick & George, Wow, a 572 Hemi on the Dyno!! This engine appears to have multiple issues, but Nick will figure them out. I'm anxious to see if this will make the claimed 750 HP. Nothing better than a Hemi on a Monday afternoon at Nick's Garage. I hope that you guys have a great week. Here We Go!
Thanks for being here, Eugene. And thanks for your confidence. Hope you're having a great summer.
hi Eugene.
@@NicksGarage I really enjoyed the video George, the music was awesome, and the camera angles were perfect. If it was my engine I would put on a pair of Carter Competition Series750 cfm carbs. Waiting for part 2 or 3 to see the final numbers.
@@ericball6000 Hi Eric.
Hello Eugene, How are you enjoying your beautiful Charger that Dr. Nick completely rebuilt for you a few years ago? You must be loving it on the beautiful Texas roads!
Need to get a SpinTron to test engines, like this especially before starting, it will turn motor over usually up to 500 rpm and allow you to get a wide variety of information before actually firing it up
Hey Nick I don't trust that cap and I don't trust that rotor.
Can't wait for the next episode thank you twice.
Great to see you and brother working together! Didn’t see anything about checking to see how washed down oil was, I’m sure it was diluted. I’m sure Nick you will get this beast running great again!
That was really interesting. Thank you Nick, you are incredible, George, and everyone present. What a great show. Can't wait for the follow-up
Thanks so much!
Good old Phil called it again with the single carb. I love seeing Nick and Phil working together we can REALLY learn some stuff. Love from Australia🇳🇿
Right on!
I've been a Chrysler guy for more years then I can count, my 440 with my AFB runs like a watch, run good gas and it's never failed me.
Nick. You knew it was out of time on the first back fire We were all waiting for you to catch up.
When it pops back through the intake it's getting spark when the valve is open.
Trust but verify.
Thank you Nick & George another great Show 😊
Our pleasure!
Im right with nick, im 64 and spent many years rebulding carbs & I grew to hate Holleys with a passion brand new ones were almost never plug and play jet changes and float bowls gasket upgrades from the old cork were the norm, they nearly always seemed problematic and needed endless tweaking and tinkering --- worst of all is that they STILL use that dam power valve thats toast after one good backfire, that doesnt happen with other carbs except maybe a ford autollie, also a holley design -- I always did great with a quadrajet, a carter or similar the Edelbrock four barrels.
I don't like Holley carbs either because they have 22 places to leak fuel butt for drag racing nothing beats a double pumper Holley
The carbs have a check valve in the throttle plate to protect the power valve from backfire. Even before Holley put in the protection it was highly exaggerated.
I do admit that they dry up from sitting unused, though.
On my 67 cougar 289, i put a 600 holly on it in 1983,its still on the car and has never been taken off,runs great!
I’m right there with ya!
You may also have the spark wires in the wrong cylinders (two cylinders on each side).
I have a 572 BBC with lots of extras I run 108 octane fuel …. Nick did you measure the vacuum and put in the right size power valves ? Just asking I’m sure you did and I hate 600 Holleys ….🇺🇸👊🏼👊🏼✌🏼
Great video and yes that engine really chugs
I agree with Nick.
Take the existing manifold and carbs off.
Install a proven carb and manifold on and see if the engine is good and will perform.
Change the oil and filter, the gas went somewhere.
Cut the filter apart and inspect for metal and contamination.
Thanks for sharing. 👍
Have a great day.
Het Phil!.. I always enjoy seeing you on these videos.. You remind me of a fellow I once knew.. he had two PHD's and was smart as a whip. he was a good friend.. I miss him.. They sell things on facebook.. I just thought it was a place for juveniles to go and spit at the world and each other.. at 73 I never even thought about it, though my brothers and sisters are on it.. Maybe I will give it another think.. What a shame about the engine I was a Holley fan in my younger years but after sitting like that they do need complete tear down and cleaning.. Thanks guys I love these trouble shooting videos.. Plus the tear down vid's
Back to basics…..check timing, spark plugs and fuel delivery…….never trust anyone but yourself! Good video as to what happens when you skip these basics!
That’s GOT to be the world’s largest 4-cyl!!
And the least fuel efficient.. damn
Hah!
With 4 cylinders not firing right, lots of un-burned fuel will come out the exhaust and show a rich reading on the O2 sensors. That’s the problem I would investigate first. Am I missing something ?? In my opinion, it’s not a carburetor issue.
Awesome I will be here waiting for the next go around awesome video Nick and crew keep them coming and see you Monday
Thanks 👍 See you then.
I never take for granted that people tell the truth or know what they are talking about. Obviously it was 180 out at the first backfire! After that i would check over everything and assume everything is a mystery
Shocked you guys didn't realize 180° right away?
Excellent channel 👍 Thank you
I do a lot of reverse rotation marine engine and see this alot
Air idle bleed emulsion tubes get clogged gummed up alot on Holley flood o matics .
Cause rich idle .
I'm looking forward to seeing that big motor on the dino running good and what it will do. I'll bet it is a monster!
It's 180* out soon as I saw flames out the carby and big caugh, easy tell-tale signs, first thing you check easy to overlook but !
That was fun, was glued to the screen 📺
Awesome. Thanks!
Nothing wrong with Holley carbs, when you know how too work on them. Helps when you use the correct model for the application.
The 600s are ok and will work well when tuned. I would remove the choke assemblies, though.
Good video, glad to see some frustrations and learning
Awesome Dyno Day 😊👍
I would probably drop oil & filter on it because the oil is full of undurned fuel & the last thing you need is ring wash because of all the fuel washing the oil off of the rings and cylinder walls . I remember watching that episode with that Ford that was in the trailer that sat & you were having a heck of a time trying to get it to run to get it in the shop last winter because those carbs sat with old fuel that basically destroyed them from sitting . You hit the nail on the head on the problem and its a very good idea to stop & swap the intake manifold & go to the big single 4 barrel to get it running right to find out how well it runs and make some pulls just to see how close the power numbers are . Another great video from Nicks Garage !
Rule#1: people will lie to you. It should be obvious by this time that it wasn’t put away running. I had that same problem with my first engine, but I was 16. 180 degrees out.
Check for a firing order swap cam. I suspect someone swaped out the dist. In storage And timed it 18436572, or it came from a swapped order motor. The only way for a 18436572 motor to run that even on 4 cylinders is if the end cyls on one side and the center two on the other are not working. That's not what you have going on. Could be wrong, tho. Anytime you have a dead cyl upstream of an O2 sensor, it will read rich even if you lean it out until it dies. Also, if it has a flat tappet cam, was it broken in correctly? I'm not familiar enough with them but it seems like a good high compression new 572 would work that starter harder? Also, it may be a trick of the camera but the rear carb seems to have much smaller venturies than the front carb. Good luck, Nick!
Evenin Mr George an Mr Nick! Have a Great week!!
Same to you Pappy! Thanks for checking in.
Shocked the timing was trusted with all the bangs through the carb
The accel pumps are delivering enough fuel to start the motor. After the first carb backfires it was obvious the ign timing was off quite a bit. Floats stuck. Carbs are all gummed up.
Timing Timing Timing ‘. I had 2 #1’s on my Distributor Cap on my 383 after Rebuild and Obviously we tried to start it and i was standing over top the carb and Boom 💥 my hair was on Fire and my Eyebrows and Eyelashes burned 😂
Boom!
@@NicksGarage whats odd is they don’t kickback when they are that out of time they just Blow through carb and Burn 🔥 our Faces and Laugh 😂 at us ‘.
My experience with those 600 vac sec Holleys is that they run great new out of the box, but once they need a rebuild, sell them at the local swap meet. You will never, and I mean _never_ get them to run right again no matter who installs the kit and adjusts them. I don't have that problem on the 4150 based carbs, just the flat bowl transfer tube 1850 based units.
I repair 600s ,up to 5 a year, they always run great!
Nothing wrong with a 4160.
Nick will fix it! We have faith in our MOPAR God
I've been enjoying watching you bring this beast to life Nick
I'm kind of surprised at the buyer bought this not knowing anything about what was in it whether the lifters were solid or hydraulic?
And as you discovered it wasn't even run before it was put up for sale
But once it's running that idle it sure sounds like a beast
And how would you know what the lifters are without pulling off the intake manifold?
And then if they are solid what's the intake and exhaust clearances?
Other than that it's been another enjoyable video life and thank you !
As soon as it backfired the first time I’m unsure why the timing wasn’t checked, I was screaming pretty loud to check timing but nobody heard me haha
That's insane! You are the man Nick
NICK'S GARAGE NUMBER ONE ALWAYS
That motor wasn’t ready for the dyno. You can’t expect something with carburetors that has sat for 3+ years to just work. That guy should have had the carbs gone through before it ever came through the door.
I missed you this year in Carlisle Nick! However I had a great chat with Manny and Robert.
First crank at 6:55 fuel is going past the needle&seat on the rear carb already. Most of the fuel is in the oil now. Love the channel Nick, but man you gotta run the pump for a while and check that before trying to start it, especially after seeing the rock hard pump diaphragms.
Yes from the top view you can see it was pouring gas in there. Some gasket is leaking or the floats were stuck. Maybe you could set up a monitor to see that view while you are working the throttle at the dyno.
I believe the O-rings on the needle/seat assemblies dried up & overfilling the float bowls.
I thought it was strange to spray starting fluid when fire was flying out of the engine, Nick got it figured out !
I'd suspect both power valve diaphragms are dried out as well as stuck or dried out acc pump diaphragms. Could be adding fuel through bad power valves , sounds overly rich beyond jetting or idles adjustments . Nick will find out what's what though .
O-rings on needle/seat assemblies, too.
Dana "60" Glass. I remember one engine you had on the dyno that gave you fits. The '70 Boss 302 motor. There were a few others that were frustrating, but the Boss stood out. I knew you would get the big HEMI figured out. With properly adjusted carburetors, this monster should get at least 700 hp or better.
Can't wait to see what numbers this 572 runs at 👌
Havent seen Nick this fired up in a long long while.
Tabarnak indeed, bon vidéo comme toujours Nick
Merci!
Check the pin on the cam side gear,had a 79 351 Windsor motor that would run great but when it backfired,I had to pull out the distributor and rotate it 180 degrees for it to run again, the pin that holds the gear ⚙️ on the shaft was sheared but it always spun 180 degrees
I learned a long time ago that when in this situation, start with the basic fundamentals. Check the timing and firing order as the first step. It only takes 10-15 minutes. Then check for spark. Then check for fuel. You'll save tons of time this way. I had a 440 Blues Brother replica a guy couldn't get running. It turned out the firing order was "correct", except that he wired it in the wrong direction.
Always check everything over after someone tells you it 'ready to start' after 3years storage
Nick ! The engine doctor, I learn more from Nick than anybody
Looks like the check valves in the accelerator pumps are stuck closed. A shot of chemtool down the passage will usually loosen them up nicely.
Great engine!
I personally think that it's acting like it's 180 degrees out at the distributor, or someone did the sparkplug wires backwards(clockwise in stead of counterclockwise, seen it before).
Looking forward to seeing the big Hemi running good and making a pull. You can’t trust anyone. That much fire had to be timing way off. Thanks for the Videos, Nick. Hopefully you got a good deal Gatan.
Hello Nick. Awesome video as usual. Did you ever get the old 354 Hemi done and dyno tested? I'm going to build a 392 for my '33 Dodge coupe and I'm dying to see some kind of dyno test on a Gen 1 Hemi. They are amazingly rare. I can't find any decent ones on RUclips except wild race engines. There are a couple of old magazine builds but I'd really like to see you do one. Thanks.
A spark plug with a 3/8" and 7/16" UNC bolt welded perpendicular to the hex portion of the body gives you a quick tester plug that threads into the front of most engine's cylinder head as a ground, hook the coil lead to the plug and just crank the engine. An AC volt meter across the leads of a mag pickup MSD distributor when cranking should produce a small voltage when cranking. We have a variety of spark plug leads, bulkhead fittings and whatnot to adapt any coil to any lead or distributor cap.
5:40 no need to remove the carbs, just pull the accel squirter off and stick a thin pick down the threaded hole to work loose the stuck anti drain needle that resides below the screw. EZ PZ.
Yes.
... and replace the O-rings on the needle/seat assemblies.
Wow Nick, you should have known that from the first time it happened... 95% of the time it's timing when it flames out of the carb.
