Thanks Tom, much appreciated. There are several on here that I highly value the opinions of, and you are one (my signature is a quote from another). I used yours as a guide and you have helped along the way.
The throttle body is from an '08 Trailblazer (4200). I'm going to use ALL the electronics from that vehicle. Working on the cam and crank reluctors now. Once that is figured out it should be 'game on'!

Does anyone have any opinions on whether or not I should 'smooth' the ribs in the floor of the intake or not? Injected, turbocharged 250. Will the fact that it is under boost negate any ill effects the ribs would have? Thoughts?
