Reliability tier: verified - see /disclosure/

Engine: 7.3L V8 Gas (Godzilla, chassis tune) (Ford Godzilla, 7.3L), 2v

7.3L Godzilla in the motorhome/commercial chassis calibration: 350 hp / 468 lb-ft (chassis rating vs the Super Duty truck tune, per The Fast Lane Truck), owner-reported ~3,900 rpm governor; TorqShift 6-speed (6R140) on the 2020 chassis per dealer spec listings and The Fast Lane Truck (RV Business reported a 10-speed at the 03/05/2019 announcement; the sources conflict and later years are not separately verified). Replaced the 6.8L V10 for MY2020 per the 03/05/2019 announcement; the 2020 chassis also got upgraded suspension hardware (larger sway bars front and rear, per SuperSteer).

Platform recipes (4)

• Cooling service for the 7.3L Godzilla: pressure-test, then water pump and thermostat as wear items, pump numbers split by year (mode fm-gz-cooling-service)
• Exhaust manifold leak repair for the 7.3L Godzilla (mode fm-gz-exhaust-manifold-leaks): cold-start tick and soot tracks at the flange
• Ignition service for the 7.3L Godzilla (mode fm-gz-ignition-service): 16 plugs on the 2v SOHC V8, one coil per cylinder
• Tapping that follows one cylinder on the 7.3L Godzilla: check Ford program 24B27 first, separate the oil pump drive gear (lower front, 2020-2022) from the valvetrain, then lifters and the cam lobe (mode fm-gz-lifter-cam-wear)
