I have a set of Exhaust Manifolds for a 340. I pulled these off to put on a pair of Dougs Headers. No cracks or leaks while they were installed. I can take more pics if requested.
Located in Navarre FL 32566 asking $250 OBO but buyer will pay for exact shipping. These are heavy.

Might be a little high for the later 340 manifolds. I have a set like that from a 75 360 duster that needed clean up and I think I paid $75 for them. You might post the part numbers and what years the are for. Would still be a desirable piece for a restoration as alot of manifolds got ditched for headers durning the 70's.
 
Looks like these will fit a 340 engine from 69-73. The casting date reads 11/13/1973. The casting numbers are 3614368 and 3418623. I'm willing to sell these for $100 for the pair but must insist on the buyer paying shipping. Once again I live in Navarrre FL which is near Pensacola. The zip code is 32566. Thanks.
 
That's a good deal. I thought it wasn't too unreasonable before. They look nice. Here be's you a bump.
 
The pass side is a 71+. They will fit a 68-70 car, but not correct style.
 
These are not the "coveted" hp manifolds, but I can tell you they are still a higher performance manifold for 340/ 360 the Embossed line on the passenger side lets you know that as well. They have a lot larger outlet than any 318 manifold. They are a definate upgrade from stock 318/360 stuff. I was rat holing these for a while and started selling them off. The drivers side sold for a easy 80-100 bux itself and the passenger side 40-50 bux.
Your price is good.

Even though the pass side is not the classic swept hp manifold, it is considered the HP manifold for that year. They look similar to the 318 manifolds but are different.

As RPM mentioned, the outlet size is different.
 
That is the hp manifold for 71, in fact there is only about 2 to 3 hp diff between the early and the 71 & later log, also the 71 340 was the hottest
