       Paul ,

          The total length of the intake is 10 inches fixed plus 18 inches (175mm) or

      15 inches (150 mm)........Is that correct ?

NO total lenth is 18 inches.

          Thanks for the renderings for the Delta......Do you think the "Russell"

      will fit with the extended redrive ? I like the alternative manifold except the

      external ram-air gooseneck would have to go......  < :})

I'll get around to trying that.
