    I wanted to know if you had to relocate your ac and if so, where you got the relocating bracket. Also, what did you do about the wiring harness? Are you running straight motor or have you added a poweradder?

    Here's my mods:
    97 GMC ext cab, 2002 LS6, MTI G1 cam 228/232-588/575-113, MTI hardened pushrods, Patriot 243 heads flow 300+, 3200 stall, 85mm Mass air, S&P Type III Headers, 3" Random Tech cats, Flowmasters, HPTuners, 4:10 gears, Original Boyds wheels 17X9's front 17X11's rear, East coast customs WS6 ram air hood, 150 shot NOS LS1 set up, 4/5Beltech drop, Caltracs.



    I made my own harness using my 97 and a 2002 F-body. I notched the frame for the A/C because I like a factory look. You can purchase a top mount kit from S&P. I'm currently working with a well known header company building 1 3/4" and 1 7/8" primary long tube headers. Once finished I'll post pics and pricing.

    No, I did it at my house by myself. If you need someone to perform the swap I can hook you up with some friends of mine in Pearland. Have you heard of G-Force?


    BTW, thanks 35thAnniZ28...............
