Whaddya mean there was no LS1 or LS3 in the 97-03 body style? I remember my body style having a 327 in it. Then along came the 04+ body style with the LSx in it (LS3 iirc), which was also a 327. Either way, here's what I'm talking about on my car:
Colleen: CAI, HV3, 2.5" d/p w/h/f cat. Full suspension, PowerSlots w/Hawk HPS, GR2s, Sonar projectors. Needs tune. Awaiting install of FBod brakes.
Shianne: 98 L36 MM5. Good start to a LONG project.
