Search results for query: 340 manifolds

Just be aware that the early 340 manifolds cost a lot more than they did 15-20 years ago. I sold mine for enough money to pay for the TTI headers.

Funny you ask im doing a T/A tribute so doing this exhaust which should be factory T/A challenger bend style since it uses the same manifolds to connect to A-Body T/A Exhaust System (1967-1974)-

IMHO you are always better to use the best manifolds for the car you have. There is a reason they were made specific for your car. Generally the older the better, exhaust manifolds got pretty ridiculous as time went on. You can buy ready to go exhaust and use factory tips and hangers...

Looking for a set of usable 340 manifolds for a driver car. Would prefer 68-71 but 72-74 are fine Don’t have to be perfect just not cracked or extremely rotten. PM if you have a set with a price. Thanks

500hp? wasn't the goal 12's and looking stock? Never said or was making a point that LS and 340 manifolds are same or 500 hp with manifolds is a piece of cake, talk about nit picking. I just googled manifold vs header to give the OP some idea what he might expect and was surprised there was...

Also, any names or links? Thanks!

The Later 340's lack compression, cam, and cylinder head. The stockers have more restrictive exhaust manifolds. I'm sure there are differences in distributor timing, carbruation and intake as well. The 73's did have electronic ignition and Thermoquad carbs which can be a plus. 240 net...

I have a very nice complete six-pack setup for sale. The carbs have been rebuilt, including new diaphragms. The fuel lines and linkage are complete. I have a spring kit for the vacuum pods. I did save all the old components for the carbs that were replaced. This includes the air cleaner...

My FSM left this number out. 1970 340HP manifolds. Best I could come up with (see attached) but is for different something.

92-3 ?? Dakota RT 360 Magnum 2 1/2 outlets very similar in flow to 68-71 340 manifolds

Harold started making them. Laysons has them available now. One step above 340 manifolds. (one small step) They exit in a strange place and you had better have a good exhaust shop nearby to get them hooked up. Search "Spitfire" here n the site.

Hate to get sucked in, but I can also say, I like manifolds. As a matter of fact, I only put headers on one side of the 64 Barracuda and pulled it off. Had other cars with headers and hated them. They are at the dump with the side pipes, traction bars, Holley carbs, and everything else I did...

Agree there. I was talking about the 340 stock manifolds. May have got out of sync with the thread.

And they make little difference unless you wind the crap out of the engine

...said, here's some additional thoughts on suitable exhaust manifolds. To me I basically have three options: 1) '02 Magnum manifolds, 2) 340 manifolds, and 3) 318 manifolds. The magnum manifolds have significant physical interference issues with factory A-body power steering, steering columns...

I have a super nice set of 340 HP exhaust manifolds for sale, they were bead blasted and sprayed with VHT 1500- 2000-degree paint. These are nicer than the set on my car but i don't feel like changing them out. $650 plus shipping

Hi Folks Well, I finally broke in my fresh 1971 340 build after 4 months. This engine is going into my Cruiser 1971 340 Demon this spring (hopefully). Here's the rundown on the build........ .040 Cast Silvolite pistons .018 out of the hole. Piston clearance .00075 Hastings moly rings...

Heat expansion in the length of the manifold. Expansion is X thousandths per inch, so on say 3" the expansion will be very little over #s 3 and 5, and 4 and 6, while #s 1, 7, 2 and 8 will be considerably more length change. I believe the conical washers let the manifold move a bit under them so...

Looking for late A-body 340 ('71-'73) exhaust manifold cores to port. Date codes not important, just the correct casting numbers: #3418623 (passenger) #3614368 (driver) Cheaper the better. Can meet up within 2hrs of lower NY/NJ/PA/CT area or meet at Carlisle in July.

I didn't mean cast manifolds, I was wondering about some kind of tubular manifolds made from header tubing into a log style tubular "manifold" with an outlet similar to a regular cast type manifold. I certianly understand all the steps to produce cast manifolds.

73 340 driver side 2 1/4 outlet and 93 Dakota passenger side manifold 2 1/8 out let with head pipes to fit automatic trans with manual or power steering. Located in Los Angeles $500 for everything

Nice original set of hipo manifolds for 68-71 340s. $550 plus shipping. Thank you

Never a waste of a stroke.

Even a stock 340 will see benefits from a full 3" exhaust with 3" constant diameter mufflers. That is, AS LONG AS the collector diameter is at least 3". If you're running 340 manifolds, then 2.5 is about as big as you can go.

Thanks for link. They are 1969 X heads, the manifolds for the 273 are 1967. Thanks

Here's a brand new set of Doug's headers for a good price. [FOR SALE] - Doug headers smallblock I run the 71-73 340 manifolds and on the passenger side they are under 2" at their exit point. I'm going TTI longtubes over the Winter and on a stockish 340 may not see much of a gain but I do like...

There was a manifold shootout a long time ago in one of the mopar magazine I think, they found one of the magnums and one of the 340's gave the best result, can't remember which side was which, but there wasn't a huge difference between the 340 & Magnums and even the 360 ones too. Here's...

It would have power wise for sure but still cast crank etc should have also come with a bigger then the 340 cam 340 will always be the Baby Hemi Forged crank full floating rods windage tray hp manifolds and 2.02s =big block killer

I am selling a 1970 numbers matching H code Plymouth Duster with original 340 motor, manual A833 4-speed trans, 8 3/4 sure-grip rear end with 3:55 gears. It comes with two hoods, two sets of wheels and tires, two air filter housings, and the original exhaust manifolds. It is triple black, with a...
