    There may be one or two on the motor. They are typically on the lower portion of the block near the oil pan rail. It's an odd-lookng cylinder that just kind of sticks off the block with no apparent use or reason.

    Yep, near the starter, if your 5.7 (L05) is like mine (I just pulled the one from my C-1500 1993 Burb). It's above the pan line near the dipstick aperture. Look on the opposite side of the engine and you'll see a drain plug with a square head. I mention this to remind you, the knock sensor works by listening in engine's coolant. Remove the sensor and be ready with a bucket (even with the radiator drained). There's not much excitement down there, why do you want to know?
