As I didn't win the Westfield manifold on eBay it looks like I will be building one.
I am thinking 1½inch primaries with 2¼ main pipe. Does this sound OK or should I go for 1¾ primaries with 2½ main pipe.
It will be a standard (for now) 2.0 Zetec with TB's or Bike Carbs. I am likely to upgrade next winter to an improved head and new cams.
