I've measured my own catalytic converter's housing with an IR thermometer at 800°F, about 30s after shutting off the engine. Yay, mixed units!
Stirling engines are fun because they can operate with a very small delta-T, but I haven't seen a compact, inexpensive, powerful Stirling engine. Come to think of it, I haven't seen a Stirling engine do any work aside from rotating its own shaft. Rankine is probably more realistic.
