I'm pretty sure this is that same 3800 motor that gm uses in my mom's 2001 buick Le Sabre. Her intake was the fiberglass resin plastic and the torque specs are 89 INCH pounds. Make sure you use the right tightening sequence too. 89 inch pounds is for the upper intake or Plenum. 136 inch pounds is the torque specs for the lower intake
