[Alpines] welding manifold

I think you'll find that "40" is the venturi size and "35" a series number.

  A related question .. ?

  The Holbay engine Sunbeams used Weber 40DCOE35 - I think. I'm pretty
  sure they were used on Hunters, not sure about the H120 Rapier.

  Does the "35" in "40DCOE35" indicate anything in particular ?

  I tried to find this on the 'net but no luck.

  Perhaps the "35" is the choke size?

  I've seen a writeup; will look.

  Manifold off a Hunter has to be cut and arc welded minus 10 degrees of
  slope to offset the Alpine vertical engine setup. Hunter engines lean
  10 degrees.

  Acutally that maybe should be 11 to 15 degrees if those carbs prefer a
  5 degree slant to work best.

  I've seen dcoe's on alpines but never asked which manifold.

  As noted the stock alpine manifold will work excespt that port sizes
  do not match.

  The SAOC England has an article about doing this.  Anyone have a copy
  handy?

  Hi folks,
  has anyone cut and welded an aluminium intake manifold?
  In theory it could be posseble to cut and weld a H120 dual weber
  manifold to fit series Alpine, but I am quite sure the intake channels
  do?'t hit if there is a part missing. Has anyone tried?
