For hating working in front of the camera, you did a great job of making an easily digestible informative video.

[@OllamhDrab]

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. Sometimes I can be in teacher mode, sometimes... nope. :) (And if I put up any KZbin videos it'll just be giving back to the general pool of random people filming how things come apart and the easiest access on a given vehicle, even if they aren't always exactly experts. I think they're unsung heroes in a world more or less without shop manuals. :)

Simple Craftsman hand tools, simple logic applied, simple engine to work on. The "technique" is simple as well; his hands move almost identically to what mine do to this day. Those hands are seriously seasoned. Pure "Point A" to "Point B" wrenching, no flash, no textbook sanitary - just exactly what is needed to do the job, nothing more - and tempered, oh so very tempered, at every step by years of experience in knowing what could go wrong if done differently at any point. It's a pleasure to watch Tony's videos again. I like this course of content creation and think it does the hobby a world of good that it gets put out there. This is the stuff young skulls full of mush need to learn so that the hobby survives. Good on ya, Tony. - Ed on the Ridge

[@Fubarfighter]

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.

[@ddrewable]

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!

[@JMTiedemann]

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!

[@seanbryant2848]

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!).

[@roberthill2219]

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.

[@travisy7861]

[@hankhessig6586]

Beautiful and Happy sounding machine Tony. Great to see here in full swing and not just in the driveway at home !!!!

[@auteurfiddler8706]

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.

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.

[@gilbertnowak5770]

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.

[@ccpgmike620]

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!!

[@dieselstuff2952]

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.

[@MrTheHillfolk]

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.

[@clembob8004]

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.

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.

[@clembob8004]

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.

[@nathanwhatley2160]

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

[@jeremypike9153]

So when I raced dirt track we figured out that the 2.3 ford ohc inlines we raced wouldn't open up a small 4 barrel carb. We figured out that you got a much smoother air fuel ratio with a 500 cfm 2 barrel Holley than anything you could obtain at the "time" with a 4 barrel. Now there were guys running over a 300 ci stroker version of the 2.3 litre ford and yet all of it came to the conclusion that the 2 barrel big Holley offered the best afr which equated to the best power available. I'm not sure how this equates the the slant six but it may be something to try if the engine isn't asking for the extra cfm give it what it wants and focus on concrete changes like pistons camshaft and compression as well as camshaft timing.
