1965 396 Exhaust Manifold.... Original or Repro?

[David S.]

Hi Guys,

I'm looking for some insights here. I was wondering if someone could tell me if these are real 1965 BB L78 (396cix425hp) exhaust manifolds or if they are repro. What are the tell tell signs differentiating original manifolds from repros?

Best,
Dave

My opinion is that they are originals. I think you will find that the reproductions have a "coarser" texture than the originals. Actually, the finish texture on the reproductions is very similar to those big block manifolds cast at Tonawanda. However, I don't think that the original 1965 manifolds were cast at Tonawanda.

I agree with Joe. Most repo cast Iron parts are cast overseas & the mold sand & the iron they poured were not as good as American foundries. If these are reop I see no duction.
