A major auto manufacturer rarely releases a new engine line. In most cases, the manufacturer will stick with several generations and iterations of an engine that is known to perform. An example is the 5.0-liter Coyote now entering its fourth generation in the S650 Mustang. However, Ford Motor Company made a big splash when it decided to develop a 7.3-liter gas engine for the modern F-250 and F-350 Super Duty trucks. The old 6.2-liter Boss engine was headed for full retirement and the truck needed something with a little more power and modern machining to back it up.
Fast forward a few years, car builders got wind of how good this truck engine was. While few were quick to jump on the 445-cubic-inch platform, most waited to ensure there would be aftermarket product availability, which Boss engines have lacked in recent years. After the Godzilla engine became available in crate form and aftermarket manufacturers began building for it, the engine quickly became the hottest swap option from Ford.
Megazilla incorporates everything wanted to add to the original Godzilla engine. Pistons, rods, CNC-ported heads, and intake manifolds.
Early adopters of the 7.3 realized that the engine was built solid and for the most part, could make serious power with the stock block and crank. Where the engine needs some attention to make more power is in the pistons, cams, and heads. Designed for stump-pulling torque, the engine isn’t geared toward top horsepower numbers. Ford Performance knew this and wanted an option for a boost-capable Godzilla engine that could easily handle boost.
Enter Megazilla, A 7.3 Godzilla With Built Up Internals Ready For A Boost
The new Ford Performance Megazilla crate engine will feature CNC-machined heads, Mahle Pistons, and Callies H-Beam forged rods, while still retaining the production steel crankshaft. Buyers will have the option between two camshafts, one aimed at low-end torque and the other at some extra top-end horsepower. The former banana-shaped throttle body intake made for the F-250 and F-350 packaging restraints has been removed and a streamlined version has taken its place with a 92mm GT500 throttle body. All said and done the engine produces 500 lb-ft of torque at 2,500 rpm and 640 lb-ft of torque at 3,800 rpm. Peak horsepower comes out to 615. All this while remaining naturally aspirated!
The Megazilla will come equipped with a straight intake manifold with provisions to run a Shelby GT500 92mm throttle body.
If the Godzilla engine is on your slate, but the thought of building it for boost worries you, now you can relieve yourself of that fear with the Megazilla crate engine. Besides having a cool name and being the perfect jump-off point to a forced induction build, you’ll save time and money by avoiding the machine shop to have both builds take place.
