You may also find this interesting as well ? I found some info on another forum posted by Lee from C&L ... Some of you may (or may not) know this, but we have developed a completely new intake manifold for the 3 valve engine as well (Doug has seen it), and it was first displayed on September 1st and 2nd at the 35th anniversary MCA meet last year. We are trying to finish the tooling, but we do not have an "exact" time frame nailed down, as it is a "big" item.
