Why wouldn't you use the older 3L intakes off the taurus, they do not have the secondaries and are quite a bit smaller. Upper plenum finished.
MY idea for the OHV 3.0 WOULD work on the Duratec. Listen closely before you get angry. I'll even post a pic to help.
I believe that would solve all problems when used with the 3L Duratec upper plenum. This was pointed out to me after I started designing the OHV S/C ... DOH someone thought of it first! hehe
