Haha guys do that with wing samples at the airport. But that shit evaporates in about a minute and doesn't stink bad. We save it and burn it in the mower,that 100LL smells great !
Those slant sixes are surprising for it's small displacement, my mom had one in a volary station wagon and when I first drove it I thought it was a 318 I was quite surprised when I went to check the oil and saw the leaning tower of power!

I think it's a different kind of 'work' UT doesn't like to be filmed at, where he gets in a certain zone. This kind of stuff is just kinda demonstrating the routine for him, I think. :) (It would be hard for me to do a lot of that, even with patient camera help.

"QUICKIE"? Nice to see a video longer than 10 minutes. I don't care what TH-cam says. When the Gearhead Monk speaks we listen! The longer the better in my opinion.
Need to get you’re hands on an ‘Aussie speed’ intake manifold which has runners that are very similar in length. Helps with jetting & tuning also has more low down pull. Best slant manifold on the market
Great video. I have not seen anyone else go into such detail on the topic of plug-tuning before. Obviously not rocket science, but the level of detail is more than meets the eye. I think most of us go for gross step-ups in power, where your limiting the inquiry to a specific context gives a lot of ideas that are generally ignored. When I was watching super stocks in the heyday, I often wondered how some, like Sox and Martin, Ramchargers and Grumpy Jenkins would consistently be class winners, while many others with essentially identical cars would not. I knew some cars would say "tuned by Joe Fabeets" or whatever, but did not know exactly what it meant.
If you can't get the blue gaskets and have to use stock type gasket there is a trick. Get some Chapstick or Vaseline and coat the factory gaskets real good on both sides. Next time you pull the bowls it comes right apart. After you take apart just add a coat before you put it back on. I coat the blue withem also just for insurance. Works real good on the bowl screw gaskets also.
Nice video. As always,inspirational to me & at my age i need inspiration. Main difference in our daily activities Tony is that you're there doing it in a shop & i'm here in North Alabama working under a canopy in trailer park. Now i'm going outside to work on the '65 Coronet.
Im just starting my venture into carbs. my 74 challenger has a quick fuel 650, these videos are, if nothing else, taking the stress out of opening one up and playing with it! Thanks Tony! Also if you remember i asked about my car fighting to stay alive in gear on one of your lives. turns out i had 9-13psi of fuel pressure. we put a regulator in, brought it down to 6psi and that fixed the issue!
Generally I love my Fords; I have Fords, but there's something just so sweet about a slant six, and the sound of a Chrysler starter motor from this era... so sweet...
Yeah, the slant is a great engine, even stock. They purr like a kitten forever with just the most basic maintenance. And the Mopar starter, there is not another sound like it on the planet Earth. I used to think they sucked, but then I found out that the gear reduction really helped in cold weather cranking (and believe me, up here in ND, cold weather is a thing!).
@@clembob8004 ... thanks for your comments... being from upstate NY, we have it cold up here, too... cold weather cranking power is a must-have for us too!
The Mopar Bible specifies popsicle stick air dams inside the intake for fuel distribution problems like this. A flexible fuel line allows the bowls to be removed without removing the fuel lines. It costs about 20 dollars more. You can slice an all metal line and put some flex hose in the middle. The Roadkill guys have a good video on carb tuning with an Air Fuel Gauge, though it is meant for a street car.
i think we use to use chapstick on the paper gaskets in a pinch on the dirt track on late night tunes on holleys,use too race the iron duke engines and been thru the same with four cyl class,need every bang for the buck
Ive done the same build...Put a 77.4 on the north side and add 6 spacers on the first pump, then use a non stick gasket under the scoop. I recommend 6/8th german wrenches...reverse thread of course. Fill er up with 214 Octane rocket fuel and off you go!
I wish your channel was around 15 years ago. I wasted tens of thousands of dollars on my old charger and hardly got anywhere. I could never find a mechanic like you that knew what he was doing.
@@MrSwinger1 I agree, I'm not saying anything bad about the shops that worked on my car. They did their best, but I should have found somebody who knows mopar like Tony. I could have saved a lot of money and headaches
@@MrSwinger1 thanks for the response and I agree again. I was aware of the high cost of modifying and repairing a vintage muscle car(especially a mopar). I just didn't do my research and find the right shop.
Many years ago, a family friend whose family owned the local MG dealer, was screwing around with intakes trying to get the optimum mixture, just like Uncle Tony is doing. He found that putting a step in each end runner helped clean up the fat condition on number one and number four. I remember this in particular as a kid walking into the garage on a visit while he was stick welding some material about a half inch up from the port in each end runner of the intake, an inline 4. Said it was an old trick from the BMC racing team in the 60s. This might be something worth pursuing using high temp silicone or something along those lines.
just wanted to say thank you uncle tony, you have helped me with my 318 though your videos so much and I appreciate you taking the time to put these videos out.
I think it’s time for an uncle Cathy shout out on the next video ! We all know that without the women like Cathy in our lives, life could be significantly worse ! For those that wrench on muscle cars, big trucks, or whatever the hell it might be, having a significant other that understands and tries their best to appreciate our sickness and addiction is a priceless addition to our lives and success in my opinion ! And I think appreciation should be shown ! That’s all. Hope u got something outa that. See ya tomorrow 😀
I don't know whether Uncle Cathy does it in everyday life, but she has remarkable self control in not saying a word when there are times where most could not do it.
Tony there is one other Trick you can try if Jetting does not make you totalaly Happy. In Roundy Round cars with Strait 4 cyl they use DEFLECTION PLATES to Divert some of the fuel from going to the furthest Cylanders. They us this when Dino-Tuning the 2.3 For Pinto motors. IT IS A POWER MAKER! They make the plates from Sheet metal and trim them to suit the amount of fuel they want to go the the furtherst cylinders.
I should have mentioned this before when you did UT, but I wish I would have known about the differential jetting on an inline when I had my F-150. Don't know if it would have worked on a 500 Edelbrock. But I could never get rid of an off idle stumble, but once rolling, it was a beast. It had a 300.
@@pookysdad4884 nothing wrong with that , screwing around with epoxies isn't uncommon when involved in port issues along the entire intake tract even the port in the head.
Wow you did all this without a cigarette in your hand, what is the world coming to. LOL ROLL UP YOUR CIGARETTE!!! GREAT TUNING VIDEO!!!👍 GREAT CAMERA WORK ULTRA KATHY!!! Those plugs look pretty good and with that jet change it should fatten up 3 &4. Look forward to seeing what kind of time Plan Z runs.
Silicone spray helps a whole lot with keeping gaskets from sticky. I spray carb gaskets before installing them and they won't stick if I have to remove them.
A-plus tutorial, Tony. Well done. I'm guessing the ram-charge effect at low rpm of the long runners to 1 & 6 are aggravating compression & cam mods... so they're fat at low rpm. You might want to refer viewers to your video on the Chrysler 'Cross Ram" or Plymouth "Sonoramic" intake manifolds where you explain the concept. Also this level of jet management or tinkering is not just Uncle Tony, or just drag car knowhow. It's old skool tuning know-how that was used in all forms of auto racing. The early Porsches had flat fours similar to VW Bugs. by the late 50's the ran two two barrel carbs. In tradition muscle car lingo the carbs sat East/West. For hill climb races the Porsche factory used different jets for the 'front" vs "back" barrels to compensate for the different level in the front of the bowl vs the back of the bowl!!
Hey tony love your highly advanced technical carb tuning secrets! I have a 232 I6 jeep. So relevant to me since I have just added an offy manifold and a 450 4-B. Can you use a holly with idle in all for corners? Guessing there is not one on the spare parts shelf? And my shop teacher told me the the throttle plate controlled how much fuel and the jets controlled the ratio of air/fuel. Just trying to set up a stump puller and sand dune runner-upper. 😎 Again love you channel! Keep going!!!
Okay, now I know what to watch for on the plugs. I still haven't decided on a carb for my slant yet but I'm going to run a Weiand manifold. I was looking at a 500 to 600 cfm setup cause mine will be a corner turning road car but seeing how your carb is working I'm going to think on that a little more. Thanks Tony!
It's a Holley Tony....easy enough to modify for one idle circuit to feed both end cylinders. I'm just a couple of years younger than you, and made a Rochester Q-Jet run hard on a 1600cc L16 in a Datsun 510. Was not easy but I have been into carburetion since about the time I was potty trained. And dude, buy a jet wrench.
Careful cleaning those metering blocks and stuff. Years ago when I didn't know what I was doing too much , a buddy said his car ran like crap. We suspected a carb issue so we took it off and the butchery was everywhere , all kinds of scraped off sealing ribs and stripped you-name-its. I was smart enough to know that will mess with the carb circuitry. He went and got a new carb. They've got all kinds of little raised ribs on them to seal off passages , and it's easy to scrape one while removing those stupid gaskets. Can't say I've been around em enough to figure a decent way to clean em ,other then being careful.
This is why I stay away from Holley carbs. I don't like the design that can cause leaks so damn easy. I once put a 650 Holley on a 318 and had nothing but trouble with it, could never get the thing to stop leaking and it didn't perform all that well. Then on a whim, someone gave me a 780 Thermoquad off of a 77 Cordoba 400. I chucked the Holley, put on the T-Quad, and my God it was magic! That thing ran great, no stumble no bog, just pure ass acceleration every time I mashed the peddle. Then I put in a 1" carb spacer and removed the secondary metering rods and it only got better.
Hi Tony, I re jetted.both of my c3 vettes, and re timed the distributors, and I learned it from you. I believe you discussed the jetting issue awhile back. BTW, it helped.
Curious about re-using the same spark plugs for a color test. Will a dark brown plug go back to clean/white in a lean condition? If so, how many minutes at full throttle will it take?
I saw a guy on a Facebook Mopar page offering an original Hyper Pak setup, with an original Carter carb, rebuilt. I wonder if that would work better than your current setup.
Thanks for clearing up the sideways carb experiments. I still think it's worth more experimentation, but it looks like you'll get it working just fine that way. What I'd like to see is the carb turned with the primaries to the pass side, then compare that to having the primaries on the drivers side BUT with a primary metering block on the secondary side of the carb, so the idle circuits feed the secondaires like Chevy did on their medium duty truck engines. But I ain't trying to tell you what to do... maybe I'll try something like that on one of my old Chevy 6's, if I ever find a 4bbl manifold for them.
Tony i bought a 350 edelbrock 600 i got it to run great and now I'm stumped it just quit running right when you put in gear and hit gas it tries to die but I'm almost convinced its carb clogging or bad gas but it idles fine
Tony curiousity: watched the old powernation doing a video on a 4 cyl they did with a single manifold like that for a track car. They used a flow diverter cut and trimmed in the intake to better direct the air/fuel.... any chance that may help as well? Please note, most of what I know about carbs and intakes comes from you, those series, and a few other youtube vids. Only performance carb I've ever messed with has been on a sub 50cc 2 stroke in a huge rc plane or car...
I know this is a bit off topic, but I wonder what an intake manifold with longer runners would do? As I understand it, part of the advantage of the slant (and also the long runner cross ram intake on some of the 60-61 383s and 413s) was the "supercharger" effect that the longer runners had for the fuel/air mixture flow into the engine. I know that would be opening up a whole new can of worms because I know it changes the torque curve at certain RPMs, etc, but it would be interesting to see what would happen. I think it could ultimately squeeze more power out of that slant, but I know it would also require some tuning and tweaking. Just a thought.
The Australian Chrysler Valiant E49 had a 265 ci hemi straight six that wasn't a cross-flow head that used a six pack intake, wonder if that could be adapted.
My 340 build in 73 had the carter AVS stagger jetted and the venturis cut to work with the LD 340 dual plane manifold.. Something racers did then you wont see now.
When i’m tired of working on my old piece of shit, i watch other people work on their old pieces of shit. Thank you tony

Back in the days before blue gaskets, I read to use chapstick on them before assembly. I did. It worked.
The blue ones stick too just not near as bad. Chapstick helps them too.
Great video, can't wait to see her fly down the track !!!👍👍

Then on a whim, someone gave me a 780 Thermoquad off of a 77 Cordoba 400. I chucked the Holley, put on the T-Quad, and my God it was magic! That thing ran great, no stumble no bog, just pure ass acceleration every time I mashed the peddle. Then I put in a 1" carb spacer and removed the secondary metering rods and it only got better.
Please do a video installing a cam shaft on like a old school big block or even small block just love the video quality! Keep it up man
Uncle Tony if this TH-cam thing doesn't work out,you would be a dammed good Hand Model...
LOL
Keep doing u info cool 😎
That little 6 Sounds great! Can't wait to see how she runs Saturday night at the track. Would love to see a time slip
Reaction time 60' ft etc .
Thanks Tony.
The best 21 minutes of your day beeecheezz
You could take that thing to Mexico and test it 3 or 4 more times before going to the track Saturday. It would save a month of track tuning.
Hi Tony, I re jetted.both of my c3 vettes, and re timed the distributors, and I learned it from you. I believe you discussed the jetting issue awhile back. BTW, it helped.
Staggered jetting, a time tested strategy.
I suggested that last video he basically told me I was wrong….
@@jeremiewampler I guess it's HOW ya say it 😂
Learning so much with these videos!
Always enjoy your videos Tony.
Old hotrodder told me one time to help atomize fuel stack carb gaskets and aluminum door screen
Curious about re-using the same spark plugs for a color test. Will a dark brown plug go back to clean/white in a lean condition? If so, how many minutes at full throttle will it take?
Time for a SMOKE!!!
Tony, sometime maybe talk about the crossfire 6. Firing 2 cylinders at a time?
I saw a guy on a Facebook Mopar page offering an original Hyper Pak setup, with an original Carter carb, rebuilt. I wonder if that would work better than your current setup.
Thanks for clearing up the sideways carb experiments. I still think it's worth more experimentation, but it looks like you'll get it working just fine that way. What I'd like to see is the carb turned with the primaries to the pass side, then compare that to having the primaries on the drivers side BUT with a primary metering block on the secondary side of the carb, so the idle circuits feed the secondaires like Chevy did on their medium duty truck engines. But I ain't trying to tell you what to do... maybe I'll try something like that on one of my old Chevy 6's, if I ever find a 4bbl manifold for them.
Tony i bought a 350 edelbrock 600 i got it to run great and now I'm stumped it just quit running right when you put in gear and hit gas it tries to die but I'm almost convinced its carb clogging or bad gas but it idles fine
Tony curiousity: watched the old powernation doing a video on a 4 cyl they did with a single manifold like that for a track car. They used a flow diverter cut and trimmed in the intake to better direct the air/fuel.... any chance that may help as well?
Please note, most of what I know about carbs and intakes comes from you, those series, and a few other youtube vids. Only performance carb I've ever messed with has been on a sub 50cc 2 stroke in a huge rc plane or car...
Should you not remove the washers on those plugs with using the drool tubes?
Awe Man.. I wanted to see a launch... I know... At the strip....
You ever go to George Rays?
I know this is a bit off topic, but I wonder what an intake manifold with longer runners would do? As I understand it, part of the advantage of the slant (and also the long runner cross ram intake on some of the 60-61 383s and 413s) was the "supercharger" effect that the longer runners had for the fuel/air mixture flow into the engine. I know that would be opening up a whole new can of worms because I know it changes the torque curve at certain RPMs, etc, but it would be interesting to see what would happen. I think it could ultimately squeeze more power out of that slant, but I know it would also require some tuning and tweaking. Just a thought.
Is there a performance gain by taking the crush washers off the spark plugs?
Any time I change jets, new or used, I like to run a piece of fine brass or aluminum wire through them just to be sure that they're clear of debris.
I wish you could have worked on my 650 dubel pumper on my 340.
The Australian Chrysler Valiant E49 had a 265 ci hemi straight six that wasn't a cross-flow head that used a six pack intake, wonder if that could be adapted.
Nah not a crossflow and getting rare nowdays.
@@aftermathau I said 'not a cross-flow'...
@@luvr381 sorry my mistake :)
What? The Hemi 6 is NOTHING like a slant 6.......the head's aren't even similar.
My 340 build in 73 had the carter AVS stagger jetted and the venturis cut to work with the LD 340 dual plane manifold..
Something racers did then you wont see now.
Ya what? LD340s have a squarebore pattern...like the AVS. You cut them to fit the spreadbore Thermoquad. Or run an adapter.
