That was a fun vid. For the Mopar man the SA publication The Carter Carburetor is a good one too. It isn't a pocket book like your Holley book but it takes the novice on a journey to carbi-land LOL. At the end of the book you gain a sophisticated understanding not of just Carter carbs but all carbs. For the novice, the author imparts a better than trade school education for a general stream mechanic on the relationship between manifold vacuum and Venturi vacuum. Of course those crazy Italians Bernoulli & Venturi feature prominently but in a way that keeps the reader curious to always go to the next step in the book. You can just about feel your mind opening when reading it. The pictures of Mopar carb setups are always fun. Years ago after reading the book this small engine mechanic tried to tell me the operation of a particular diaphragm carb and I just looked at him with a blank face because I didn't know what to say to him. He tried to tell me the diaphragm is part of the choke mechanism. He's been 'tuning' carbs for years without understanding how they work FFS! I attempted to tell him and he just talked me down and told me I had no idea what I was talking about and it's too difficult to explain to a novice - even though he knew I'm a qualified mechanic (I thought well you would say that particularly when I'm right and you're wrong). After reading that book my joy is modding Thermoquads.
I have been using a vac secondary 600 with just the choke removed. I am going to replace it with a used Demon carburetor with downleg boosters and slightly larger bores, and see how it runs with that.....but it is vac secondary as well. I spy a manometer back there!!!! that is what I use to test flow. Thanks for braving the cold to bring us some useful tech.
lol anytime. The test that shocked me was test #5( mod 4 ) micro material removed. The jump in cfm shocked me. 🤫 that water gauge was built to fix air airbox problem. When I find some answer I might share my journey. Good luck with your demon👍👍
Different flow benches will give you different numbers, but you use the same bench and show a huge gain in flow from the benchmark. Shows that removing the choke isnt a huge difference so keeping it isnt going to hurt much.
Yup 7 cfm in total by destrying the choke Tower and blending it in. The 26 cfm from removing the tiny lip around the bore. aka The final test was the one that Shock me.

There's more to be gained smooth boring and booster contouring. Additional mods using a 750 or 850 throttle plate, gaskets and redrilling for matching fuel ports at throttle plate gasket..
I have seen when they take the boosters and thin them down as well and thin the thickness of the butterflies too. Would be cool to see just how far you can take this little 600?
The reason why i didn't do them mods. Is that they will mess with the factory calibraton of the carb.....You really need to be brushed up on idle and main air bleeds as well as pv restricton and emulsion mixing.........all of which the average carburetor rebuilder Can NOT. DO or understand If you can rebuild a carburetor, and have a dremel tool, you can do these mods and still rebuild a vary nice carburetor ;-)
I think a good test would be to measure the airfow with and without the choke tower with an air cleaner and the lid at various heights from the carburetor. I imagine that the height of the lid would make the most difference in whether or not the choke tower was removed. I'm also confident that the contour of the air cleaner base will also benefit the tower deleted example more. Maybe I DON'T want to know how much time that I may have wasted!😮😢...😅
Hmm thats a vary good question, and a interesting one............ thanks for your thoughts and coment.:-) Since i have allready maxed out my bench, i would have to do that test on a 2-Barrel Carburetor.!???----...........Hmm
@CudaFishEStories It MAY work with the 600 because the air cleaner very well may cut the airflow down(?) Wish you could test bigger carbs where some modifications may be more significant.
yeah so do I. the bench was build to flow sb mopar iron heads that will NEVER SEE 500 CFM ....from dyno test i have seen the air cleaner base, usally made more power........Curiosity sure is gettting the best of me.
I'm most concerned about the flow with air cleaner lid comparing with and without the choke tower. There's not a lot of sense in using a high flowing intake manifold and big carburetor only to choke it with a very low profile air cleaner for lack of hood clearance.
@@mickangio16 I have been under the weather and still haven't go my flow bench video releassed.......and still waiting on my adapter for the carburetor. But when i get my adapter, I think we can test all of this and more;-)
You can base plate out to 850 has bigger butter flys and change out boosters to down leg thats lot work but if you're running class were they have cfm rules its big in difference in performance
Agree. but thats way over the top, of the simple thing you can do without a lot of the knolage of the inter working of a carburetor. Thanks for sharing.
great job showing what each mod is worth! man for a street car leave the choke on and do the other mods and you can still gain a bunch of flow, it looked like the whole choke horn was worth about 7 cfm which I would leave if cold starts are important.
Mind you, this was a down and dirty job. No time was done to make all the radius smooth and constent.......but i agree. The lowest improvement was the choke tower. I was surprised as well.
@@CudaFishEStories of course, not a criticism at all just stating you can stil have a street carb with choke and still gain alot of flow with your other mods!
If the carb was tested in the correct direction of flow the air horn removed would show more improvement. Carburetors are not designed to flow backwards😂 venturi effect will increase flow also and removing the little lip as the final step will alter the design to pull fuel out of the boosters . Good video though. @@CudaFishEStories
@@rossmason4434 Thanks for the complement. I'm realizing that i should have put a streamer on the butterflys to show the direction of air flow. The air was being pushed into the carb and out the butterflys instead of pulled thru the carb. Stay tuned, we are about to test it both ways (sucking thru and pulling thru the carb)
I love your numbers do you have any tips on the vacuum advance modifications I would love to see more videos first time watching you I don't know if you have any more out there let me know I got two carburetors I'm going to get after and get some more flow
Welcome, John C if you buy the spring kit for the vacuum advance, it has a chart in there to show you which one comes on when also in the book that I recommended it also is in there. My biggest tip would be to buy the vacuum, or the secondary housing that allows you to change the spring without taking the housing apart. That housing will save you from replacing the diaphragm every time you change a spring.
I enjoyed this and have twin 600s on my blown 440 so may need to talk to you about doing this but they run out of fuel at 6500 and that's not good. Also thought about changing it over to duel feed bowls. Vacuum carbs on a motor that does not make Vacuum lots to talk about. How do I get a hold of you. I thought about a pair of demons too.
I sent you a e mail to "spanboats@yahoo.com" from your about page look in your e-mail /spam folder for a flashgordon. we can also chat here if you like, but we can get into a longer conversation on yahoo.
The email that you have on you’re about page doesn’t work, but that’s OK. We can talk here. The first thing I would do is depends. Can you put bigger bowls in ?which way are the carburetor setting on the manifold if the fuel bowls, are facing each other you can’t put the bigger bowls in. If they are facing passenger, side driver side, then I would definitely put the larger center hung float bowls and get rid of that stupid transfer tube that goes between the two bowls on the carburetor you have now. The needle and seats are a bigger diameter on them bowls and will flow more fuel.
@CudaFishEStories actually it works fine and has for 25 years at least. What it doesn't work for is this Google based thing called utube and if you don't conform and use Gmail they block it if you have Gmail. When Google went into my phone and took all my pics and videos and I erased them from my phone that's when I got bent. Fought for months to get them back and they were so messed up and some gone. I am at the point of starting a Gmail just for this site. So there is that. I am 64 and hate typing book reports and I use the phone for its intended original purpose lol. I'm not doing things this way.
@CudaFishEStories I just left a comment and utube sensored it. Because I complained about this sensoring my emails. This has cost me a lot of money too.
LOL You may just get your wish, as i may do another video testing air filter and carb spacers exc. this would require me turning the carb right side up. if i do that video we will start with that test.
@@CudaFishEStories I will be watching. One thing I have never seen is a good comparison on the bottom plate of an air cleaner. Factory GM high performance have a big hump surrounding the air horn opening. Many aftermarket are flat. Roadkill garage got the best flow using a salad bowl and not one of those velocity stacks. Comparing all this would be quite interesting. I have heard from back in the early 70's that the stock GM high performance 14" air cleaner was one of the best flowing and from what I know about sharp corners, radii vs mutltiple angles, I beleive it. What I know is certainly not a library of physics data so I am always learning.
The results would be more accurate if the airflow was from the top down. Carburetor are not designed to flow in the reverse direction. It might flow more in the correct direction.
Your right. This is simulating forced induction and can tell you improvement but not accurately. The air needs to be drawn through the carburetor from still air. But you can tell by their response, you’re not going to “tell them anything”…
You can tell me anyting I'm all ears :-) ......as far as....is this a fair test or am i testing it as if, i was was a flow throught aka Blow through carb. Well i may have to make another video on that test to prove it right or wrong. Notice that i didn't say to prove me or you wrong............you and i will find this answer together. just like in this video, i didn't know the answer until i make the video. Cheers.
Needs more then building! Needs air bleeds changed! And a carb has metoring blocks no valve bodies! But it was interesting how many cfms where picked up! But we trash those carbs now days!
Thank for your coment. Agreed i couldn't have picked a more lame Holley carb for sure. :-) Yeah it need atleast a pair of center hung fuel bowls to get ride of the transfer tube, that leaks every time you do a jet change. My last one i built i used the 3310 metering plate in the back and both bowls.........It ran.......ok LOL
I think i will do a video on it but just incase i don't get around to it. Its Called A "PTS Flow Bench" and it didn't caust me 10 of thousands of dollars either!!!!! Im all about do it your self and this bench is not any different. You buy the plans from Bruce for 50 or 100 bucks..... i cant remember and them you build it your self.

You have no idea how much i Wish i had one of those, and could do that. Remember the title of this channel. Im a poor man that has to improvise to make it happen. The one thing you have to remember, with that statement, is if the eng isn't requiring it, it would be a 0 HP gain.........A hot rodded big block that you had just pull that tiny carb off of.......then yes i beleave it would!!!!!
To me that sounds like false advertising. Say that carb is a 600 or 650 and it only flows 518. Then it’s a 525 if you ask me at most it’s a 550 without all that work that you put into it. That to me is a long way from a 650
I’m sure that the first mold or the first carb that came out of the first mold that was clean prepped and assembled by hand flowed 600 CFM. Documented that carb. I also agree however, it does suck.
I can't make my videos better without your help. Tell me what kept you from watching to the end. And Thanks for posting up. I'm looking forward to your response ;-)
@CudaFishEStories my ADD and unfulfilled satisfaction for results after each modification. I understand that you said you'd show all the results at the end, but with seeing the gains, that you said were "interesting", I couldn't keep interest. Nothing personal. Just the way my brain works. I was really interested to see your results. It's in my watch later play list. So I'll get back to it eventually. By the way, I appreciate reaching out and asking for feedback. Honestly I had a similar comment on one of my shorts where I needed to modify an aluminum block to fit an intake manifold. I didn't show the work I'd preformed just the end results, and I got dissatisfied comments.
@@arturozarate1752 thank you very much for your input. I’ve had others complain about how loud the flow bench was and I think my next one I’ll have to drop the volume down when the flow bench is running. I have to go check out your manifold short when I get a minute, thanks again
LOL yeah i only have a bullet heater that i point at me to keep from freezing. I had two coats, and long johns on. Removing the back ground noise is still a work in progress. Thanks for sharing your frustration i do appreciate you watching this video inspite of the sound quality.
I mean I like my Wideband, fuel injectors and Motec too much to mess with a carburetor. My AFR targets are on point vs a Carburetor that can be basically uncontrollable in certain spots. Bet the same engine with a carb vs properly tuned fuel injected, the fuel injected gets more power everywhere.

they are flowed at a different depression which he pointed out
I thought 4v depression is 1.5 and 2v is 3.0, or is that vacuum, and or visa/versa...
1.5 inch of mercury equals 20.4 inches of water. My bench reads in inch of water. ( Hg)
54 CFM should be good for 20 + horsepower. A Dyno would have been nice. To see the hp differences,

@CudaFishEStories my ADD and unfulfilled satisfaction for results after each modification. I understand that you said you'd show all the results at the end, but with seeing the gains, that you said were "interesting", I couldn't keep interest.
Nothing personal. Just the way my brain works. I was really interested to see your results. It's in my watch later play list. So I'll get back to it eventually.
By the way, I appreciate reaching out and asking for feedback. Honestly I had a similar comment on one of my shorts where I needed to modify an aluminum block to fit an intake manifold. I didn't show the work I'd preformed just the end results, and I got dissatisfied comments.
@@arturozarate1752 thank you very much for your input. I’ve had others complain about how loud the flow bench was and I think my next one I’ll have to drop the volume down when the flow bench is running. I have to go check out your manifold short when I get a minute, thanks again
@@CudaFishEStories ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,the volume went so low ; that i had to max out my stereo volume to hear the video
I'm going to watch it again
but your saying that the volume was low through out the video, just my voice or the sound of the flow bench.
Flip the carburetor over and test the flow in the correct direction.
The video is okay.
Just please flow test the carburetor in the correct direction.
Keep your eye out for that video. lots of interest in this subject so i'm haveing a new adapter too do just that. Comming soon ;-)
What's the noise in the back ground can hardy under srand your hill Billy accent
LOL yeah i only have a bullet heater that i point at me to keep from freezing. I had two coats, and long johns on. Removing the back ground noise is still a work in progress. Thanks for sharing your frustration i do appreciate you watching this video inspite of the sound quality.
Merci,, But you make a lot of noise,, haha,, Good test thank
Thanks.
Them flow benches make a lot of noise when the air is running thru a restriction. I probably should have dropped the sound a little bit more.
@@CudaFishEStories Thanks again, but, just work in a day times, you wake-up averybody here in Canada.
Come on dud clamp that part down. Nobody is in that big of hurry.
I'm having a adaper build so i can flow the carburetor in its normal position as we speak. stay tune.............
any ZERO that uses canned air is areal HACK. THIS MAN HAS NO IDEA WHAT HE IS DOING
lol, Thanks for Sharing.
I mean I like my Wideband, fuel injectors and Motec too much to mess with a carburetor. My AFR targets are on point vs a Carburetor that can be basically uncontrollable in certain spots. Bet the same engine with a carb vs properly tuned fuel injected, the fuel injected gets more power everywhere.
@@MrGsxrme and what do you do when your throttle body is to small…you would probably buy a new one…. I would bore it out. Get some of them free HP
Thank for sharing
