1971 340 exhaust Manifolds in Nice shape.................$850.00

H22A4 said
These are not the early 340 hi-po exhaust A body manifolds, correct?

Just to clear things up here:

623 Right hand AB and E body 71-73 340
553 Left hand A body 68-71 340

So these are 1971 manifolds.

The 549 and 553's are the 68-70 340 manifolds pictured above in abodyjoe's post.
