Do i want OEM exhaust manifolds?

Thanks- that's what I'll be doing,giving it more time to consider. But... I may post a WTB for the correct exhaust manifolds.

That's exactly what you should do. The #549 and #553 manifolds fit the A body 340 cars as well. There is often a set or two floating around FABO at any given time. It's interesting the price increase in those things in the last year or two. For a long time, a nice set would sell for $500. Now they are $7-800 with the really nice pairs commanding upwards of a thousand.

There is this and there is that. I think you can find this easier and cheaper than that.

I'm will be putting my six pack on my AAR, was going back and forth on the header/ manifold, car will look stock pretty much anyways, so going with the manifold. around a 500hp stroker into a long head pipe into power stick chambered exhaust pipe, similar to the innards of the side pipes on the older vette's. Then found a place that sells AAR stainless exhaust tips that are not baffled in the trumpet outlet. probably will be loud as hell, but I'm good with that.

Sounds Perfect!
Kinda thinking I should have stayed with the manifolds myself. I used the 440 carbs on my 6 barrel intake. My 340 is close to 440. Runs excellent.

The driver side If I recall right was used up through 72 on A bodies.The passenger side was 68-70 A and E bodies.

I do remember someone was or did reproducing them. But I didn't know that they still were.

At $600 for new, I'd get a set asap and at least hang them on the wall like Excudame.

I took some time and searched for the repops. No one stocks them any more. Herbs Parts has a note on their website that they are no longer being manufactured and they are exploring remaking them.
Note: "exploring having more cast"

Sort of related question: I am replacing the 318 in my 70 Gran Coupe with a 340. I have manifolds from 71. Are there any issues with fit in my 70? I also have a firm feel power steering box. Will be dropping it in in the next week or so. Probably go with a TTI setup.

Thanks

You should have no problems. The 70-74 engine bays are all the same and your 318 & 340 are the same external size. If the 318 with manifolds fit, the 340 with the same manifolds will fit. You mention probably going with a TTI set up. If you're talking headers, pay attention to the footnotes for the set of headers you are considering. TTI has been at this a while and their stuff fits very well.

Mopar to ya!

No. It will be the 71 340 manifolds. Thanks for the info.

Nice looking 340. Check your intake manifold coolant hose, looks like it is almost pinched closed.
