289 vs 318 ..... Ford vs Mopar

318's durability is 2nd to none. However, I've not experience any 289's coming apart, and we've owned some higher mileage cars.

My '67 Cougar had a 289. I raced a guy one night and heard a "kapow" and the engine died. Pulled it apart and found the nylon timing gear had sheared the teeth off.
