Found a used LQ9 6.0 motor, harness and computer out of an 05 Escalade. Plans so far are LT headers, camshaft, new springs, gaskets, timing chain, oil pump, new head bolts, valve seals and guides. After I get it on the stand, tear it down I'll know more. No hurry wanting to drop it in, I'm shooting for a February or March finish time. All boils down to how the internals look.
