First Guess: "PowerTorque" does not reman engines. There's no PowerTorque building, no PowerTorque machine shop, no employees boring blocks. O'Reillys buys from some other supplier--perhaps multiple suppliers--and then slaps their sticker on the crate.
Mass-market, production-line reman/rebuilt engines have been popular for decades. They're generally built to the lowest-practical price point, and often built with loose tolerances and "generous" clearance. (i.e., built half worn-out.)
They're "perfect" for vehicles you're planning to sell soon. They become Someone Else's Problem. Grandma would do OK with one--low mileage per year, no performance expectations other than it runs.
