For sale 9/9/68 date stamped 340. Runs and currently in 69 dart. Has good 340 exhaust manifolds. Vin LM23P9B187942. Trying to sell entire car but if you have matching vin and trying to locate original engine I have it. Putting a silly # on it of $5000. I have videos of it running. Located in...

what is everyone using for exhaust that actually clear the p/s , the column and gear box? shorty's, 340 manifolds or ?????

Early or late 340 manifolds? They're different. So first off, see if it clears the manifold. Then lay it on a 340 head, you'll see what has to be removed. If I remember correctly, early 340 heads (X, J) have ports that will outsize those gaskets. Later 340/360 heads you may be safe with, and...

Was thinking of converting 90 degree adapter to plate style as pictured but not sure if there will be a clearance problem with my 340 HP manifolds anyone running this plate with same setup?

I bought these for my ‘67 Barracuda and to make them work in my application I’d have to modify the steering column tube. My car is all original and I don’t want to cut the tube. I’m looking to sell or trade them for 340 manifolds. $450 located in Woodland CA 95695

I I must of read the same article, because I read the same thing, years ago. I never bought a new 340 car, so I'm not sure if that is correct. All the 340's I have played with had a gasket of some sort. My thinking here is, if I recall correctly, you say you rebuilt a 318. It appears you may...

thank you.

I would like the 68 69 style but 70 E body would be ok also

A 71 340 was the fastest year and it even had restrictive manifolds because of the awesome spread bore on top of that intake and intake was a great design also but that engine produced some serious power

I got a set of 69/340 HP manifolds and I want $750 for them plus shipping and that's what I paid for them 2 years ago...got a set of 71 style for $575

Can we see pictures of the manifolds? If the previous owner did these mods they might have used 340 Manifolds too.

Since they come with gaskets from the factory and I have never read anywhere that 340 exhaust manifolds don't require gaskets, throw that article out.

Sure, they bolt on just fine, they just don't flow as well as the 340/360 manifolds due to the smaller port size. They tend to blow gaskets too because of that.

Exactly. Place an LA 340/360 intake gasket on one of those Offenhauser dual quad manifolds and you'll see why they cannot be bolted to the 340/360 head and actually seal. The SB 340/360 671 Blower kits used a modified dual quad Offy with welded up port areas. The welding added material and...

May or may not be much difference but may have leaks on a 340/360 head.

There are some mismatch issues between the 340 manifolds and magnum heads. A thread or two on here discusses that.

probably because that equates to a 30 hp increase. Are there any tests showing these kinds of gains? I didn't read through the whole thread again.

So I bought some manifolds that I thought were the two and 1/8 in outlet opening but they turned out to be the later model 94 and up exhaust manifolds. The guy advertised them as the early model manifolds with the two and 1/8 inch opening which I already had one of which I am going to use on my...

I put in too much cam on mine.... sounds good though

'68 - '70 340 manifolds are all the same and only available used. In '71 the passengers side was changed to a more restrictive center outlet design but driver's side the same. Reproduction nuts/bolts for 340 manifolds are available. The driver's side heat shield is not being reproduced...

I had magnum heads with 340 manifolds I ran remflex gaskets for a magnum engine no sealing issues

340 HP manifolds.

Anymore install tips/tricks guys? I'm installing Summit 2.5" #680144 header back, but lm using hipo manifolds with the 340 in our 67 cuda. Thanks

273, if you're plan is to install on 340...don't! Either go the hipo manifolds (correct for your car) #'s 2863549 and 2863553 or go headers. Those 273 manifolds are worth $50 tops.

Dam, first it was the 8 3/4, then the LD340, then the 340 manifolds, then the 340 valve covers, then the 340 air cleaner, now the V8 center link ? Sweet Baby Jesus !!!!!!! I'm going Cheby. :rolleyes:

I have a very nice set of 1968-1970 340 Exhaust Manifolds Sand blasted and painted ready to install. 900.00 OBO

There two 340 intake manifolds one blue paint is date is august 11th 1967 and other march 17th 1970 $160 each and or trade one of that I am after OCT or NOV 1969. Shipping not included.

This whole system is under 4 months old with less than 300 miles on it. It’s a set of 10/30/69 Dated manifolds(no heat riser), correct manifold hardware, TTI 2.5” head pipes and as much of the mid pipe as you want up to the mufflers. This is all in a 67 Barracuda Automatic car, should be a...

70 Dart with 340- Headmanns- Junk crushed passenger side collectors - installed factory manifolds and exhaust...fits nice:) P.S. Id run the Headmanns open at the track but not on the street...

Id go with the 340 manifolds for sure.
