I am a little new to the 3.8 V6's, as I have had a few 5.7 liter Vortec trucks, and a 4.3 liter V6 Blazer. I just bought a 98 GP GT with "motor issues". Previous owner replaced the intake gasket, and a week later the car shut down on him. The motor will crank, but not catch. I also just purchased a full 99 GP SE parts car, minus the hood, front bumper, passenger side headlight, and passeneger side fender incase i have to do a motor swap. My question is this, can i just swap on a metal Series III Intake Manifold, with the upgraded aluminum GM or Fel Pro gaskets to the Series II motor?
