Ad text does not claim the engine is original to the car, but implies it is. The V0128DZ stamping does not compare to other known original stampings. Trans stamps look ok, rear axle stamp has leading C and has clearly been altered.
Restored in non-original paint/trim.
Engine stamping looks very fresh to me and it does state in the picture below that this is "original stampings".
Car sold twice at BJ (2007) & (2010). In 2007 write up stated engine was "numbers matching" and 2010 stated engine was "date code correct". The Camaro appears to have been repainted as deck stripes do no longer go all the way down the back lip. Other notable changes are the steering wheel and brake booster have been swapped out and are both reproductions.

Body tag looks original. Assuming it is original to this car, it was born Fathom Green, white standard interior.
Who knows if it was originally an RS. Checking the rear body panel is not a reliable indicator.
