Getting your hands on the upgraded Godzilla pushrod V8 will cost you an arm and a leg.
After its initial announcement three years ago, Ford has finally started selling the 7.3-liter "Megazilla" V8 engine, and it's relatively expensive. Currently listed at $22,995, the Megazilla power plant is less than $500 away from getting you a brand-new Ford Maverick (before destination charges).
However, that price gives you a modern pushrod V8 engine that effortlessly produces massive power with 10.5:1 compression. Without the help of turbochargers or superchargers, the Megazilla can churn out up to 615 horsepower at 5,750 rpm and 638 lb-ft of torque at 4,650 rpm on premium pump gas. It can even pull over 500 lb-ft as early as 2,500 rpm.
You can imagine how much more this mill can produce with forced induction involved. To handle all that power, the Blue Oval V8 crate engine comes with reinforced internals, such as a cast iron block, CNC ported aluminum cylinder heads, low-profile intake manifold, Mahle forged pistons, Callies H-beam forged connecting rods, steel crankshaft, high-performance camshaft (with VCT delete), and 92mm throttle body from the Mustang Shelby GT500.
Ford will also include the following with the package: coils, plug wires, spark plugs, production oil pan, shipping/storage cradle, and engine wiring harness. Of note, the Megazilla V8 has the same bellhousing bolt pattern as the Ford 4.6/5.4 engines and Coyote 5.0-liter, so you'll have one less thing to worry about when swapping the Megazilla into your Mustang.
And yes, despite being an upgraded version of the Godzilla V8 found on the Super Duty trucks, Ford Performance has confirmed that this engine is ideal for both cars and trucks.
Admittedly, however, this pricing would make builders think twice or thrice, especially with more affordable (and equally powerful) options in the market. Dodge Direct Connection offers its Hellcrate 6.2-liter Redeye (making 807 hp and 717 lb-ft) at $12,995, while the non-Redeye version (717 hp and 656 lb-ft) only asks for $9,495. The Challenger SRT Demon 170's power plant is pricier at $27,695 but produces up to 1,025 hp.
