My question is what is the casting numbers for the 318 and the 340 I know are different high performance and will A body dart duster are they the same because people saying they're the same and I don't know around that steering column driver side would be different

It depends.
The 3614395 is for 73-74 A body.
The one ad I pulled up said 318, but it looks like a 340 manifold.
First, what head port are you running?
You can't seal a 340 manifold on a 318 head, unless you have a later air port head.
Then, no pre built pipes are made to use that manifold in an E body.
If you need a set of 340-360 manifolds, I have a set available.
They are technically 73's, but fit the same. .

My three team is a 1983 which has the air injection holes in the heads it just seems like they make so many styles for A and e body it gets confusing how much do you want for yours and yours is correct for a 318 style not the high performance 340 correct

Here's what the good 340 exhaust manifolds look like. Anything else isn't going to flow as well.

Yeah, Xcudame, how much are those?
Spikey, those are 68-70. They are better than the style I have available.
The ones I have would be an upgrade for a 318, and are factory for 71 up 340.

A lot! I seen them for sale at $1200. Look around you never know. I don't no If they sold for that? I put a set like that on mine. ECS made the head pipes for me. My manifold are probably mixed years but I don't care.

The regular 70 head pipe should have worked fine with that 72 340 A nody left manifold.
The 4388 has just a slight bit less rise away from the head, othereise the same.
The manifold mentioned in the first post is a 3614395, A body 318 and different port and flange.
The good 340 manifolds could be worth more than $1200, if no defects or pitting.
