Thanks Peter. Can you tell me who ACCS are and how to contact them. I have seen them mentioned several times in forum posts.

Thanks Bryn and guymd. I will check these out.

My manifold doesn't look like these though. The exhaust pipe union is at the rear end of mine rather than in the middle. I wonder if they differed from car to car?

I don't know why the shapes are different, since the two links I sent you both claim to be for 318 engines. But the one whose title begins "Dodge 318..." is linear in the way you describe, with the exit at one end.
Although it states that it's from a 1956-1958, maybe it's correct?

Bob.... it would be interesting to see a picture, of your exhaust manifold(s) and of your engine. Your manifold doesn't look like the one in this listing does it?

..... which is for a later or LA designation 318. Not the original Poly Wide Block (official designation is as an A engine). This would mean your engine had been swapped for a later LA. The definitive test is to look at the lower edge of your valve (rocker) covers and see if they are scalloped, as in the attached picture. If yes, you have an original-style Poly, if no, you have another engine, more than likely an LA 318.

Edit: I should add that a complicating factor is that the early 313 Bristol engines were really 1960 Plymouth units, and the later 318 Bristols probably had the Dodge Dart unit of 1964 or so, with a four barrel Carter instead of the 2 barrel unit affixed by Dodge. Pictures of your engine could possibly help clear things up. Do you know if your carburettor is a Carter 3131S by any chance?

Bryn, I have attached some photos of the engine and tried to show the manifold as best I can.

Ve-e-e-e-ry interesting!! Then what you have is (apparently) a later poly, but still a poly 318. The 410 parts book that I have lies in its teeth....well, at least about the manifold shape.

The good news is that there should be no problem in finding one. I believe that this is one:

..... and here's another:

..... snap one up, Bob!!

Note: the critical thing to look for is that the square 'oles are upright, not angled, as they would be in the later LA manifold, which otherwise looks very similar.
Note 2: the colour is also quite interesting. If originally red that indicates a Dodge rather than Plymouth origin. Nice clean engine BTW.

Bob..... when you get the chance, I wonder if you could do me the favour of removing your air cleaner (it should come off once the single butterfly nut is undone) and look on the body of your carburettor for an ID number. It may be in two places, firstly possibly on a triangular tag, but secondly and always at the base, front left side, facing forwards. There should be 4 digits followed by an S. I would be very interested to find what carb is on your engine.

Please also note that I posted a rely to you on the previous page.

Thanks Bryn. All very interesting stuff. I am in London today, watching England being outplayed by New Zealand in the cricket match at Lord's.
I will check the carburettor number when I get back.
the manifolds you sent links for certainly look more like mine. I'll follow them up later too.
Thanks again
Bob

There is no number on either of the places shown in your diagram but there is a number stamped on the left hand side leg as you look at it from the front of the car - that is the other side from where your diagram shows it to be. Unfortunately this is somewhat obscured by a clamp holding a rubber pipe and I do not have the means to remove it at the moment. The number starts E7A 32.... but I can't see the rest of it.


I have tried to attach a photo.

Is this of any use?
