I'm totally stoked I've found a 6.0L (LQ4) out of a '03 Chevy with ONE(&#33 mile on it for around $2K. No ECU, no wiring, but it does include a water pump, alternator bracket, coils, manifold w/injectors, rails.

Its an ebay motor. Schram Auto Parts to be exact. Anybody have experience with these guys?

Another thing is the throttle body is drive by wire. How hard is it to convert a truck like mine to drive by wire?
Meaning: how hard is it to find a suitable mounting position to mount the throttle pedal?
