Ford’s 7.3-Liter V8 Megazilla Motor Makes Its Official Debut

The Megazilla comes with a cast-iron block, forged steel crankshaft, Callies forged H-beam connecting rods, Mahle forged pistons, CNC-ported and polished cylinder heads, a low-profile intake manifold, and the 92-millimeter throttle body from the Mustang Shelby GT500, which alone adds roughly 10 hp and 15 lb-ft of torque to a stock 7.3-liter motor. There’s also been the deletion of the variable camshaft timing system, as emissions and low-speed drivability are not concerns with engine swaps.

Ford’s standard specification leads us to believe that the engine was built with supercharging in mind. Mike also notes that the team built the new engine with boost in mind. We know the Godzilla is easy enough to supercharge, and power outputs can be pushed well beyond 1,500 hp, but it is certainly initially designed to simply run on pump gas, with the same 10.5:1 compression ratio as the Godzilla.

The Godzilla retails for $9,175 and weighs 580 pounds. Ford’s Megazilla engine will only go on sale in the second quarter of 2023, obviously with a higher sticker price.
