you got any pics of the manifolds this guy is trying to sell you? the 340 pieces (like abodyjoe is showing in post 15) are (from what I know) quite rare and can be expensive.. can I ask you how much he wants for them?
I have one driver's side 60's 340 manifold but it's promised to member "rockramcharger". I haven't heard back from him in quite a few weeks but he has sent me a deposit on a set of 340/360 manifolds.:
