You are correct, it is not a four corner idle carb. Always good to check in case a previous owner swapped blocks and drilled the body to convert it. But the images on Holley's website show a four corner idle carb - that's Holley's mistake. Their circa 2018 catalog had it correctly described...

Find yourself a used copy of Holley Carburetors and Manifolds by Bill Fisher and Mike Urich, any edition. You're buying for a good intro into how carbs work and the diagrams, not the marketing content. Alternatively for less, the smaller Holley Carburetor Handbook, Models 4150 & 4160...

Good guess but not correct. -7 is the revision C is the dichromate finish The number underneath is the date code. For example, from the 2018 catalog. So either the current revision changed meter blocks etc, or the photo is wrong because the marketing staff is clueless. My bet is the latter...

Here's a step by step approach. Gages and loggers are not neccessary for most tuning. Tune for Best Performance. The fuel mixtures need for different loads are described in this post. Wideband and touched on here Large RPM and Vacuum drop when shifting from park to gear I'd spend the money on...

An AFR gage isn't going to help. AFR numbers aren't targets. They're reference points. Performance is how to determine if each change is toward or away from the goal. Save your money and spend the time learning what each circuit does. Then you'll understand why the sequence in tuning is...

Stall rpm is arguably just a way to compare similarly manufactured torque converters. Its common use I think obscures the operation and effect of converters on engine load. I'm no expert on this. In general I think its safe to say that a lower stall rpm will have higher load on the engine at...

So glad mine came with that gage too. :thumbsup: You can play with the secondary opening point, but its a bit of a guessing game. I'll come back to this. The PV number has NOTHING to do with the fuel mixture. That's the opening point (vacuum) for enrichement. At wide open throttle a 6.5...

Neither one is really correct. The second one is closer to the functional reason for enrichment. Enrichment is needed under heavy load. Manifold vacuum is a good indicator of load. Do I hear you ask: How heavy? How does that translate to manifold vacuum? It depends on the engine. An engine...

OK I see the screw there for the pump cam Here's a double pumper with the choke removed. Is anything different on your causing interference other than the choke? arrow just points to the screw holding the pump cam.

Where's the cam?

Yup. And its approaching that time of year - winter fuel in the tank but daytime temperatures in the 70s and 80s for many places. We've talked about this before. https://www.forabodiesonly.com/mopar/threads/help-on-fixing-a-vapor-lock.444925/post-1972672717...

Just so we're on the same page. This is about where I'd expect the gage to be after a short drive and the engine still running. On a longer drive at interstate speeds, or in stop and go, a reading past center would not be surprising. As long as its stable, and not rising under either...

surprise, there's also bad information posted on the internet forums. Yes yes I think we all agree. It seems likely its fuel, but having a spark tester on hand will help verify that the next time it happens. Even knowing its fuel, need to determine if its too much liquid fuel into the intake...

OK. I have no youtube auto people that I can suggest for solid basics and intro. The timing light will probably come with instructions. At least enough to hook it up. Like I mentioned there's an arrow on the inductive clamp and it goes on cylinder #1 spark plug wire. #1 is front left...

Good luck then! Unless you mean the old Chrysler Master Technicians Conference. Get the basics down from the real deal the factory books; then principles, and then you can start to seperate the wheat from the chaff.

Find a new restorer. This guy is making work without good reason and wants to buy parts on your dime. Two strikes in my book. Save the money and time for the things that will actually need fixing. Heck these days one can 'look' inside a tank with scope. Be real careful removing the fuel...

You'll probably get better at collecting and documenting data as time goes on. That's just the way the it is. There's a couple ways to get the timing info if you're working alone. Of course begin by plugging the vac advance vacuum source (golf tee). The first data point is fairly easy. Once...

There is a thin insulated gasket/spacer you can buy. However before buying parts, determine the source of the the problem. A carb spacer will not solve heat issues in the feed line. Fuel filter angle looks good. You can do a bunch of investigating. When it won't start, take the air cleaner...

I've done OK with the an Innova/Equinox. I think its an older version of this one https://www.summitracing.com/parts/ino-3568

Re: Timing. and a golf tee to plug the hose while setting and measuring baseline (aka initial) timing. It is critical to measure the rpm for timing measurements. We have no way to know beforehand whether the centrifigal advance begines at 500 rpm or 900 rpm, or even higher. Chrysler's...

OK. Well that's important. If timing is far off it can put significant heat into the cylinder walls while still operating. (This was done on purpose at idle during the early emissions reduction years). Your car is a street car so timing has to be set for heat soaked conditions (unlike drag...

Beginning in 1963 Chrysler mounted fuel filters so the outlet would let the vapor out, minimizing vapor lock. Carburetion and Performance Diagnosis (Session 188) from the Master Technician's Service Conference 1970 basically same position shown in the Dodge Service Manual Then to address...

1970 Dart 1971 is similar https://www.hamtramck-historical.com/library.shtml

It depends on the details. For example: See Fuel Sending Units and A-Body Fuel Tank Map

Removed from my '67 removed from a US Build '72 Chrysler replacement 04051004

The sending units changed over the years. In part this may have been because the fuel tanks changed. We also know from Redfish that the gage unit calibration changed - I forget the year. Search will turn it up. Also sometimes the gage itself would be tweaked or the hash marks on the gage...

So what I *think* you are trying to tell us is that you are looking for a carb that will be pretty close out of the box. * You will not be taking it to the track or a dyno to tune in the full load WOT. * You will use it at least three seasons of the year. * Tuning will be somewhat limited. With...

The emissions systems are reviewed in the Master Tech Conference. Scroll down here to the year of interest and see what was new, and hten checkthe year before as well. https://www.web.imperialclub.info/Repair/Lit/Master/ If looking at the html is a pain, go over to www.mymopar.com and get it in...

I just hit Report in the lower left corner of the post. Thats the type of stuff its for. A mod or Admin will check it out and if they agree, it will disappear, as will the 'member'.
