[QUOTE="Tom S, post: 349830, member: 623"] A little cut and paste from my conversion article. The coated ones were for the swap to a 38r and the other ones are from my OBS. The driver side manifold has a longer outlet piece.

I am aware of others that did not swap out this manifold using standard up pipes but I was I wanted to be sure on the alignment with the bellowed up pipes.

I think the OBS manifold would have worked fine. International 1831025C1 or Ford F81Z-9430-AA [/QUOTE]
