The manifolds Shotgun and I are talking about are completely new castings. Ram Air Restorations (RARE) made their own casting. They are not reworked 2 1/4 inch versions. Since this guy seems like such a major PR!CK I'm waiting for the ones Shotgun described from Performance Years. I just don't like dealing with people who treat customers like this Paul from RARE was treating me. Only problem is Performance Years told me yesterday they are a month or so out from their castings being ready. So in the near future it will be RARE and a Performance Year's version of a completley new 2 1/2 inch dia. casting.
