Here's a photo as I am installing the system.  Turns out I had to
trim about 1" off the bottom of the plenum (after photo was taken) for fuel
rail to clear motor mount.  Looks even better and weighs even less {:>).

Hope to fire it up Monday or Tuesday and see if it makes any difference in
performance.  The system is essentially the same as my old system with the
exception of all fuel injectors moved to the plenum and the diameter of the
tubes slightly larger.  Old tubes were 1 1/2 and 1 1/4" dia and new one is 1
5/8" (secondary)  and 1 1/2" (Primary)  in diameter.

One Saturday I ran up the engine with the old system as a bench mark for the
new system and to 5600 rpm static.  We'll see what the new one does.
