The intake  plenum is starting to take shape.  It is tacked and/or  spring clamped together,  The injectors (Ford 42s) are aimed down the throat of the intake runners.  I glad I did it this way instead of trying to angle the injectors into the runners. I have my doubts about blasting  fuel into the  runner walls.     While the plenum still comes apart and is removable  I will go ahead and make the fuel rail. Eventually the air box  and the runners will be  one unit.  Material is mostly 16 gauge mild steel but the bell mouths are aluminum. It would be easier to assemble if it were all one or the other.
