Manifold ID in early A-Body

[65Valiant310]

Hey all,
A few years back I got some exhaust work done on my 65 valiant w/ 318 and the shop said I have some rare manifolds allowing this engine to fit in the car

Driver side manifold is part # 3614395 which comes up as a 71-73 dart 318 and the passenger side has an 11 . 9 . ($) 8 which is kind of illegible hence the money sign

Any idea what they were talking about?

Someday I may upgrade but I wanted to figure out what they were talking about...possible the driver side since it clears my manual steering box nice and clean?

Thanks in advance

Anyone running 340 manifolds on their early a-body?

I couldn't get that to work at all.

I had '71 340 exhaust manifolds on a 340 engine that I dropped into a '64 Valiant and they hit the inner fender panels HARD on both sides.

Not only that, but it was a 4-speed car and with the clutch linkage (Z-bar, etc.) adding to the "congestion" down there (T-bar, Starter, Steering box, etc.), there was no way to get an exhaust "head pipe" on the manifold. That wasn't my opinion; that was the opinion of a technician at a custom exhaust shop I took it to, for just such a purpose.

I bought a set of Hedman fenderwell headers (on sale for $38.00) and took a hammer and cold chisel and attacked the inner fender panels.... see attached photo.

Wasn't pretty, but, it worked. I'd recommend Doug's, TTI's or even Spitfire before I'd do that to a car again.

Good luck!

I have heard rumors that the exhaust manifolds from 318/360 Magnum pickup will work (in an early A-Body) with a little massaging. That would be a last-ditch alternative to tubing headers. Ask around; there might not be insurmountable obstacles in getting the Magnum manifolds on there. Word has it that the '92/'93 Dakota manifolds have bigger outlets than the later ones, but I'm not positive about that. I think the early ones are 2.25," if I remember correctly (and, I hardly ever do, anymore...)
