7.3L Godzilla gas V8 (the new engine)moderate
- 7.3L Godzilla gas V8
New for 2020, the 7.3L Godzilla is a big-displacement pushrod (overhead-valve) V8 — the largest gas engine Ford makes. Mechanics like it: strong, cheap to buy and service, and simple, with no turbo or variable valve timing to fail. It is the reason a gas 2020 is a better buy than a gas 2016–2019. Watch two things over time: spark plugs can seize in the aluminum heads (making a routine plug change an expensive thread-repair or head job), and oil leaks are common on Fords of this era. Ask for spark-plug service history and check for leaks — but as a tow engine, this is a reassuring choice.
