I am about to build an intake for my 20B.  Originally, my engine had 6

feed both the leading and trailing intakes.(the 4 rotor, Atkins...)  Do
these configurations also have the upstream leading injectors?  If that
works then why was mine configured with 6 originally?  Why couldn't a single
injector upstream be fired for both the leading and trailing phases if the
two ports shared a single runner?   kevin

It will work if you have a big enough injector. An single injector that 
will handle 100 HP is a rare beast. Also with staging you get a better
mixture throughout the HP range with six injectors.
