Which 6.0 should i buy?

I'd get an 05+ LQ4 if you can. The 05 and up motors have the stronger LS2 style rods and timing chain. If not, any 01+ LQ4 would be fine as long as it wasn't abused.

99-02 is DBC which will be compatible with your current setup.

03-0x will DBW which you will have to purchase the Tac module and pedal for DBW

05-0x you would have to make provisions for Efans since those motors will not have a mechanical fan

If it was me, I would reuse my old harness and throtle body (if going with 03 and newer) and it will be easy as cake

None of this matters....he can reuse his original accessories, throttle body, intake manifold, etc and not have compatibility issues.

Thanks! One more question. I can't find an lq9 anywhere around here (NH), but i found 2 04 lq4's. One for $1250 with 61,000 and 1 for $1150 with a little more mileage. Does this sound about rite? If it does i'll pick it up tomorrow. then i'll be ready cam and tune suggestions. Thanks again!

Sounds about right to me. I paid $1800 for my LQ4 a few years back, and I just had a buddy get one for his GTO back in January for $1300 with 65k miles.
