I figured I would start a thread on the wife's new grocery getter. Picked up a 07 LTZ with 200k on it at a smoking price knowing it had mechanical issues. There was a miss on #7 hoping it was just plugs and wires I took a shot, no luck. It ended up being a collapsed lifter on #7. Being the mileage and not sure if there was any other internal issues I pulled the motor and trans. It never hurts to upgrade while your in there right? The 5.3 is getting punched out to 3.898 (5.7) foraged internals, howard cam and springs, stock tb for now, long tubes, etc. Shooting for 450 at the wheels. The 4L70E is getting rebuilt as we speak with stronger internals a rebuilt torque convertor and shift kit to get the power to the ground.
