What ^^^^^^ said. I used N-9Y Champions for many years, Also like Autolites and Now I use NGK.
Oh really? The next time I head out I'll check the numbers and post them.That's a damn good TQ model you have. The flat machined portion on the top piece in the front indicates it's a mid 70s to 80s non emission version. The number is on the rear corner of the base plate. Should be like 6XXX or 9XXX
Hey all I have a built 360 in my barracuda with plans one day to upgrade back to a 383. The engine currently has a carter thermoquad on it and I would like something more performance oriented. I don't know much about carbs but I want my car to one day be a built daily driver, something that won't give me 5 mpg but at the same time if I give it some gas I want to go. The two question I have are one, if I get a carb for my 360 when I upgrade to a 383 can that carb transfer over. And two, what would someone with some more carb experience reccomend for a carb, that previously stated, does not give me horrible gas milage, but at the same time puts me in my seat. Thanks for all ideas and suggestions.
Uncap the bowl vent. Passenger sideI didn't mean to lol. Everyone local has told me the one I have is just a junky stock one and to upgrade to something like a holley. Here's a picture of mine.

Yep my first build, and I'm sure I've gotten myself into a deep project but its been fun so far, I don't regret anything... yet. I screen shotted the original Craigslist, thats about all I know about the engine, I could answer a few questions about it if you had any specific but thats how its built. It was originally an auto and one day I may put it back to an auto but for now its a 4 speed out of a different 69 barracuda. I have 14 inch mopar ralleyes on. I forget tire size but the backs are about an inch or two bigger than the front. Rear end it says in the add but its a 8 3/4 in a 4;10. Does this help?Can you tell us anything about the engine build?
What rear gears and size tire are you running now?
What trans mission are you running and IF it is an auto, what stall?
First build at 19?
Have fun and good luck, we are here to try and help.
The only kicker is I don't know how to drive stick lol. Here's pics of the numbers on the thermo quads, I have two. Cant tell if you can tell from the pics but it looks like the numbers on top started with a 9.Yea it does because tuning a carb is more than what is in the engine but the whole car is included on how the carb geate set up.
4spd & 4.10's?
Keep it that way!
I have that set up in my '73 Cuda.
Awwwwweee-soooooommmmme!
It is 9103S, Just got the 1 and 0 mixed up.Is that 9013S? It is hard to read. Doesn't matter. It's a non emissions carburetor so it's a good one.
Okay, I'll look into the 750 double pumpers. Thanks.That engine build is nice for a 360 backed by a 4 speed. I love a TQ, but on this particular build I'd go with the 750 dp holley for this reason: With a 4 speed and 4.10's, first and second gear will bang fast, and the air flap on the secondary's be open/shut/open/shut in bang bang bang style. In this particular build, the mechanical secondary's, in my opinion, would be ideal for this build. Besides, if your new to cars, the TQ may be a little more challenging trying to tune.
Alright ill look into the 750 double pumper. Since you've had my combo before do you remember how bad the gas milage is? I know its all about the smiles per gallon and all but I would just like to know for reference.Finally, somebody(318willrun) who understands TQs. I got laughed out of the house once for saying exactly, what you just said.
OP
I have had your exact combo, and it ran best with a 750DP. That cam is a little soft outta the gate, so 4.10s and the DP will really wake it up. And since that cam gas no chance at making any decent mpgs, you might as well shelf the TQ on this one.But don't sell the TQ, cuz you are gonna need it later when you pull that cam out. I mean in case you decide to pull out that cam. I mean that's a heck of a street cam! It loves to rev to make it's power.
But not every trip uptown involves reving to the moon.
I tell you what tho, don't be in a panic to swap it out. Your driving style might not be like mine.If you can wait until about 2400rpm (about 18 mph with your combo) before flooring it, it might be just fine for you. I just can't wait that long.I have places to go and things to do and I'm not getting any younger ya know. lol But if you do floor it before 2400, just try and keep it floored, heehee.
Oh wow alright. I'll definitely keep it then, regardless if i try a 750 or not.That's a 77 440 HP with AT truck carburetor. It's an 850. That's a dang good one.
Oh alright. Thanks. I don't have any rush to get it swapped, I'm just wanting to get her running.Like said, don't be in a hurry to swap it out.
Nobody that installs a 4.10 rear end is thinking much about mpgs. and after the 292 went in, mpgs became a distant,foggy memory of somrthing he thought he once knew something about
Which 750 would you recommend? I don't know much about carbs and even when I search just Holley 750 double pumper a huge list of them show up.That engine build is nice for a 360 backed by a 4 speed. I love a TQ, but on this particular build I'd go with the 750 dp holley for this reason: With a 4 speed and 4.10's, first and second gear will bang fast, and the air flap on the secondary's be open/shut/open/shut in bang bang bang style.

I read your article, it was very well written. I don't know much about carbs but which 750 double pumper would you recommend, I looked them up and a bunch come up. Also in your article you wrote that you were considering a turbo; is that something you think I could put on my current engine without blowing it up? I know you have to have a strong engine so it doesn't blow up with a turbo but I am unsure if mine is good enough.Like said, don't be in a hurry to swap it out.

292&4.10s pretty much means city-car/race-car, and these are like my cat with an open food-bag; she consumes for the joy of consumption.
I only kept that 292 for one summer, then I chalked it up to learning, and when a young unmarried man I had taken for a ride heard it was for sale, I let him have it,Pow. And one day maybe two summers later,when I asked him about it, he was still loving it.
I never took that combo on a road trip, so have no idea of it's potential to make mileage, but as a city-car it could burn a tankful in an evening, so Ima guessing it mighta made 120 to140miles in 4 to 6 hours. I'd call that right around 8mpgs with the Holley. I didn't run it very long with the TQ, and I love TQs!

this style....Which 750 would you recommend? I don't know much about carbs and even when I search just Holley 750 double pumper a huge list of them show up.
Thanks for explaning, that did help a lot. I want something I can drive around but at the same time I want it to have really quick acceleration, or something I could do a 1/4 mile in. It sounds like for what I would want maybe keep the 4:10 but possibly get a new intake.this style....
[FOR SALE] - 750 Holley
Let me explain a couple of things, means you say you have really no knowledge on cars.
1). Picture yourself on a 10 speed bike. Your 4.10's are like having the 10 speed in 3rd gear. In other words, to travel with other bikers on a bike path, your legs are going to be rotating really fast, while their in 6th gear and barely moving their legs compared to you. Now, if you all stopped and lined up to race, your 3rd gear will help you beat them on the start, but if racing a longer distance, they'd soon be around you. So, you have to decide what your purpose for the car is going to be. If it's going to be mostly drag racing (1/4 mile), you'll like the gears. If your going to do a lot of daily driving (some on the highway), you might want to go to 3.55's behind that 4-speed. 2.76 gears would be like 9th gear on the 10 speed bike; 4.88 gears would be like 1st gear.
2). Your intake (M1 single plane) is designed for rpm's above 3500 rpm's. a Dual Plane intake will give more low end torque, more mpg. Most dual plane intakes will make more power than your single plane under 4000 rpm's, and make a better city driver. A lot of test have been done on small blocks, and there is very little gain at high rpm's on a single plane vs. dual plane, even at 6000 rpm's.
3). If I was you, I'd purpose the car. If it's a ground and pound, slam'n gear car, leave the gears and intake. If your going to do a lot of cruising with it, I'd go to 3.55's behind the 4 speed and go to a dual plane intake. This will up the mpg, allow more comfortable 60 mph cruises, and with a 360 still pound (may actually take more advantage of the torque). If you go to 3.55's, and a spread bore dual plane intake (even a factory cast), then that TQ would be hard for me to give up......
I personally had a dart once with a 360 in it. I went from 4.30's to 3.91's, and the E.T. stayed exactly the same.
