Update on Twin H2 intake manifold

Unfortunately my design for the new Twin H2 (squared) intake manifold needs to be redesigned for sand casting.  Although the basic design is fine, the specifics need be modified.  A bit of a setback as it is pretty pricey getting the CAD work done, now 2 times.  I have 13 comittments, ad will be in the WTN next edition.  If you still have an interest I am still shooting for 30 units to get this started.
