I love this place. Thanks Tom for providing it and all the people that take their time to share knowledge and experience.

DaveRS23- Thank you for those links. That provided paths for further research. Appreciated!

Topside-Totally on the same side as you on the TQ's. As well as the right foot reality. Thanks for your input!

tboomer- Real end user experience is priceless. Thank you!

Zippy- As noted above about real world user experience. Thank you!

moparx- I'll just say some of us were not wise enough to gather TQ supplies while they were still available. Would love to run one. I know them. But much easier solutions are available for a mutt like this pickup is. And of course part of why the Demon caught my interest. Very similar, and maybe some advantages. Need to study more.

volaredon-Will send you a pm shortly

Neil-I've searched multiple times for spread bore. The only new or rebuilt stock that comes from the major suppliers is Q-jets. Nothing for Holley leading me to think the one you speak of is not currently in production. In agreement with you on the older AVS's & AFB's but they suffer they same availability issues as the TQ's as you note.

Sniper- Thanks again for your further input and like those above the real world experience is invaluable. I get your point on the SD, but its worth a look and compare.

TJP- Sending you a PM as well.

Thanks again all for your time and responses. So much better than internet reviews and sales pitches.

I returned your PM

Wrong as usual there sniper troll.

And the claim is that they work better OOTB than most any of their competitors. Not that they are 'perfect' or that they would never need any tuning. There are valid reasons why the Street Demon is a better choice than many of their very dated competitors. But you don't seem to know about any of that.

The Street Demon just happens to perfectly fit the OP's preferences. That is the ONLY reason that I bring them up. I even narrowed their preferred application substantially. They are not the end all, be all of carburetors. But they do fit the O.PO.'s preferences better than any other carb that I know of. I most certainly would NEVER recommend the CarterBrocks to anyone hoping to 'bolt on and go'. All you have to do is to look at their tune chart for the rods and mains and most guys would run the other way. Then there's the lack of ability to tune the transitions without a drill and bits. They are not a bad carb in and of themselves, it's just that there are better choices for applications like the O.P. But, if you haven't ran them on different combos to see how they work, it's understandable that you wouldn't know that.

If you know of a better fit for the O.P., then by all means, bring it up. Otherwise, you are just being yourself................as usual.

And by the way, the Street Demons new are about the same price as the CarterBrocks that you mention. And used are about the same price too. Depending on condition. So, who's stretching hard now?

So, no recommendation that fits with the O.P.'s needs, but plenty of attempts at insults.

Typical.

The reason you earned your title is that I already, in my first post in this thread, recommended the 1406.

I tried tuning this thing with that shot TQ on it and gave up. Once I get a carb on it that while not idle at 700 rpm with the primaries fully closed, (the throttle shaft leak is massive) I'll have a better chance at getting this little engine dialed in. Right now the idle is 700 to 1300 depending on how the primary shaft rotates back on let off.

Clean used Edelbrocks and Carters Competition Series AFBs can be found pretty easily for cheap, and the average dude can set them up to make them work really good for almost anything less than an all out drag car. I see local people selling like new carburetors of all makes because they got flustered when it didn't work right so they cave and buy an EFI setup meaning someone else gets a good deal on a low mile carburetor that just needs some attention.

Set the float drops in both directions (important), and then put the jetting back to stock if it has been altered and adjust from there. Most gripes from these carburetors come from dirt getting in them, stalling when turning or hard stopping (all float setting related), and heat soak. Run a filter in front of and after the fuel pump. Set the float drop measurements to perfect even if it takes some time, and the heat soak thing you have to run a good base insulator gasket, and possibly look at your fuel line routing and maybe some rubber insulation over the metal line at worst. I've never had to do that on any of mine, but some have had to. It's ok you just do what is needed for your situation.

The best thing about a new carburetor is you get a warranty if needed, and the fact that nobody has monkeyed with it. The bad thing is none of them come really ready to use right out of the box, and it's worth reading the instructions and checking things over first. They are build by people in a hurry so things may be off enough to warrant fixing/adjusting before use. I'm familiar with the AFB type carbs enough to know that the floats on those need to be verified as they are often wrong. Not a deal breaker you just know it needs checked before you use them.

1976 D100, A833OD, 318 w/ headers & Edelbrock performer 2176 intake. Cam is unknown, likely stock. If not, something near stock. Currently has the Carter TQ 9250S that was on it when I acquired the pickup a couple of years ago. And it is shot. Wiggle the primary throttle shaft and get a whistle. Although I'm a fan of the TQ's I've decided staying with one is too much hassle for this application. Going back to a 500 CFM 2 barrel might be best but that would require buying an intake and a carb. At new prices that's approaching EFI throttle body injection like fitech, Holley, etc. So for this reason I am hoping to find a small 4-barrel (600-650 cfm) that fits the intake, is dependable, and pretty much a bolt on and go.

Looking at Eldelbrock Performers 1406, AVS2, Demon 1900 or 1901. Others? Thanks in advance for all tips and recommendations.

IMO, a spreadbore carb (Thermoquad, Quadrajet, Holley 4175) would be the best option for your truck.

Years ago, I had a 1985 Dodge D150 with the 318 2bbl. I removed the stock 2bbl intake & carb and installed a used Edelbrock Performer 2176 intake and rebuilt Rochester Quadrajet from a late 1980s Dodge Truck 360 V8.

It was the best mod I ever did to my truck. More power. Fuel economy and drivability improved. The truck would start instantly - hot, warm, cold - almost like EFI.

I personally prefer the Quadrajet over the Thermoquad for reliability and performance. The Q-Jet was installed on 1985 to 1988 Dodge Trucks & B-Vans with the 360 V8 from the factory.

A rebuilt Thermoquad would be the easiest option for you (if you can find a good one). Scott Smith at Harms Auto rebuilds TQs. https://www.harmsauto.com/

The Holley 4175 spreadbore is a nice carb but is very expensive. https://www.holley.com/products/fue...ors/emissions_replacement/parts/0-80555C

An Edelbrock Performer, Edelbrock AVS2, Holley 4160 or Holley Street Demon carb in the 500-600 cfm range would be a good choice as well (and they are easier to find).

Note: You will need a squarebore to spreadbore adapter to mount these carbs on your Edelbrock Performer 2176 intake.

The Street Demon is designed to fit both intake styles so the OP will not need an adapter. Another cool feature unique to them.

If you want to buy new - check out the 570 cfm Holley Street Avenger or 625 cfm Street Demon. I don't have experience with either carb but these are the two I would look at.

Hope this helps. Good luck.
