JStew,
I will be using a throttle body (throttle by wire) and electronics (sensors, wiring, ecm etc), from an '08 Trailblazer (4200 I6). I'm going to adapt cam and crank reluctors to my motor so I can run the ignition distributorless (like the 4200 I6, LS series V8 etc etc).
Here is a pic of the intake with the throttle body on and a couple of injectors in place.....
