Did all 87 442's have cast iron manifolds?

[olds307 and 403]

There is a seller who is claiming tubular manifolds stock, I think he is confused. The car is 4 hours away.

i believe they are a log style cast manifolds. not an equal length manifold, or header style manifold.

have the seller send you a pic.

87 had welded tubes but not like a header my 87 Cutlass with 7a heads had them I think all the 7a heads did I'm not sure I've definitely seen a lot of them on 442s

The Buick parts book shows '86-87 307 Manifolds as SST (stainless steel) and not CI (Cast Iron)

Few would mistake this for a header:

Yup that's it I just didn't know how to describe that ugly thing

All VIN 9 442/Hurst engines 83-87 came with cast iron manifolds that were standard on all 64-80 SBO engines.
Only 85-90 VIN Y's came with stainless log manifolds, not sure about the 81-84 VIN Y's

All the 81 to 84 Vin Y motors I have seen up here had the #17 cast iron intake and the cast iron log exhaust manifold's, except the Hurst/Olds, A4 and cast iron exhaust manifolds. I got him to take a pic and of course not a side ways pic, so I couldn't see it. Either way the dual snorkel is there and it has the air injection tubes still in place. He said one needed replaced, it was I will wait till I actually look at it.

Hope that 442 works out for you Christian! I thought about that one real hard the first time it was listed....and like you say at the lower price too.

My manifolds from my 87 442 are cast iron with air tubes
