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?


Reach in and take out the first 3rows from side to side,The ribs were there to help channle the fuel to the end runners and they worked a little to well and would lean out the center two cyl.I have done this to many of those intakes.
