He picked up a almost ready to paint and it's finished 69' Baracuda. We were there today and he had it running. Thinks by the way it sounds it has a mild cam in it. It's a 340 car with an automatic. He said Plynouth rated them at 275 hp and Hot Rod Magazine said they really ran 325 from the factory and estimated this one at 350 depending what was done to it. He's planning on painting it black. Originally it was orange then it was painted plumb crazy.

Didn't some have a 340 have a 6 pack? 3 two barrel carbs?

Philip d · Aug 18, 2018

I'm not sure about a 6 pack on a 340? Some 440's did for sure. This one has a Holley 650 DP but he's like to find a good Carter to put on it instead.

Have he should do himself a favor and put on a new Edelbrock. Miles ahead of any of the old stuff.

When I was in college, roommate brought a fistful of new car brochures up to our room. Seems that his dad (rich wheat farmer) was going to buy him a new car, but a slight problem- he had had several "moving violations" during his feckless youth, and insurance guy said "You can't have a muscle car". Terry asked for, and got, a list of the cars he couldn't get (the usual suspects- GTO, 442, Charger, etc.). So our mission was to find the fastest car that wasn't on the list.

We went through the brochures, and it looked like the Dodge Dart Swinger with 340/ 4 bbl. might be a good candidate. He test drove it, and came back with a smile as wide as all outdoors. "That thing is a rocket", he opined, and soon the deal was closed. I lost count of how many muscle cars he dusted with that thing. A true sleeper.

That's a funny story lol. My father in laws brother bought a 340 Swinger off the same guy the Cuda came from.

cole in mo. · Aug 18, 2018

Friend of mine back then bought a new dodge challenger 340 with a 6pak, mean little car. And the 340 is different balanced than the other small blocks, if changing std flywheels or torque convertor, must be 340.

marloweg · Aug 18, 2018

had a Dodge Dart swinger 340 6 pack Hurst 4speed

Philip d · Aug 18, 2018

Wow that would be some quick little car!

Royse · Aug 18, 2018

"but he's like to find a good Carter to put on it instead."

I have a Carter Thermo-quad that may fit.
I can't remember if it came off a big block or a small block.
I believe it came off a later vehicle though.
Been sitting on my shelf for 20 years. Yours for the shipping.

If interested, let me know what measurements or pictures you'd like.
Email is open.

I'd love to see pictures of that car when it's done!

Philip d · Aug 18, 2018

Thank you Royse! I didn't see your email ,I asked him and he's definitely interested. My email is [email protected],if you can send me an email please I'll forward you his and maybe it might work?

My brother still has his 1970 Duster 340 turbo 5 speed in the garage.He bought it when he was 17. About the only thing left original, is the factory vinyl top.

I have the older, weaker brother. 1966 Barracuda with 273ci 4 spd. Had it since new. Been semi restored.

Geo-TH,In · Aug 19, 2018

Have FIL check the torsion bar supports. I had to put my 67 cuda down after the supports rusted out and front end dropped on the A frame.

No offense but I wouldn't waste my time on a Thermo Quad.
Don't care much for the old Carter AFB's that are now Edelbrocks Performer series.
Now the Carter AVS that is now Edelbrocks Thunder series is a heck of a carburetor to have. They were commonly found on 383 Road Runners and 440 GTX's but could be easily tuned to work on a 340.
I had a 73 340 Cuda with one of those thermo junks, ran 100% better when I swapped on a AVS.

Personally I'd still rather have a Holley.

The 340 6pk engine only came in AAR Cuda's and TA Challengers, but the 340 6pk induction system would fit on any of the small block Chrysler engines.

coe in mo:
273,318,340 all used the same stroke crankshaft and flywheels.
Around 72 or 73 they changed the way the engine was balanced so early and late model parts wouldn't interchange.
360 had a longer stroke with it's own balancer and flywheel.
Around the same time big blocks changed to cast cranks with external balance.

"Personally I'd still rather have a Holley."

We all have our own experiences.
I tried to run Holley carbs on a 1/8 mile dirt oval track.
On Chryslers, Oldsmobiles and Fords.
Then tried again on a 1/4 mile drag strips on big block Chryslers.
You couldn't give me a Holley for a small block engine.
If you paid me enough, I [i:c000fe1bad]might[/i:c000fe1bad] take one for a big block.

I ended up using Predator single barrel carbs on my drag cars.
Not really an option if you are looking for a daily driver.
I quit before I got into non-naturally aspirated engines.

I loved those old Mopars. Had a lot of fun with all of them!
The 360 manifold also took larger carb spacing than the 318/340 etc.

Personal experience with different brands does vary.
I have a cousin that would take a Quadrate over anything for a dirt oval car.
I never could tune one to fall out of a tree.

I started out with Holley's and learned how to make one run, I've had 3 Holley 6pk setups on different sized Ford engines 390, 406,428 and even on a little 289, love those Holley 6pks.

There were a few here that ran Predators for a while but later switched back to Holley's.

As I had said if I was going to run a Carter it would be a AVS.

Sometimes I really hate auto correct.

It should have said Quadrajet, a GM carburetor.

Royse · Aug 19, 2018

"It should have said Quadrajet, a GM carburetor."

Oh, a Quadra-Junk. I got your back now!
Nobody on my tracks even carried spare parts for the other guys.
And we all shared parts if we had them. Didn't everyone?
You can't "beat" your competition if they can't compete.

By the way, my 3 cylinder Ford x000 tractors all still have their
Holley carbs. They run and work fine for that application.
Although a bit Rube Goldberg for the job at hand.
They're not a performance or semi-performance auto engine.

timcasbolt · Aug 19, 2018

I always liked the avs. Seemed to run good no matter what was under it. The afb and performer are real easy to tune, and the choke works very well, but they just don't give you the top end like a holley. Had a friend who understood quadrajets, but his forte was restoring them to new condition. In other words, he couldn't adapt one to a non-stock application. Or perhaps I should say wouldn't adapt one.

Destroked 450 · Aug 19, 2018

Well Royse your one up on me
I never had much luck with the 1 barrel Holley's, ag or automotive.

ptfarmer · Aug 19, 2018

All the Mopar guys around here call the Thermo Quad a Thermo Flood.

huntingreen2day2 · Aug 20, 2018

Here is a picture of the 72 Duster I has with a 340 Engine.

Texasmark1 · Aug 20, 2018

Well weren't the Holleys double pumpers and 650 or so CFMs. I had my fill of Quadrajets. No way would they match.

Destroked 450 · Aug 20, 2018

You can get a Holley 4 barrel in double pumper or vacuum secondary, they make them from little 450 cfm all the way to the big 1150 cfm Dominator series.
Biggest portion of the street carburetors were 600 to 750 cfm.

I have a original 4575 1050 Dominator with the choke plate and pcv port.
Holley built these carbs to meet NASCAR rules so Ford could run them on the Boss 429 engines.
