I've recently started modding my 3800 and have realized there's alot of love for the L67 in this forum, so I decided to join up, even though I do have a Impala and not a GP.
My current daily driver is a 2004 Impala SS with the supercharged L67. My current mods so far are as follows:
K&N CAI
PRJ plug wires
Autolite 605s
Gatorback accessory and SC belts
Magnetic drain plug
180 T-Stat
Will be adding a 3" DP with high flow cat from ZZP soon, as well as a scangauge 2 to monitor KR and what not. Also planning new cat-back system with Flowmaster 40 series and res delete.
At this time, I don't plan on dropping a pulley size or anything. I'm most concerned with reliability, and with some of the OEM stuff wearing out, I figured I'd just replace with better aftermarket stuff along the way.
I'm also planning on eventually getting overkilled to support my mods, if I can get in touch with Will.
