Megazilla 7.3L Godzilla Crate Engine From Ford Performance
By Evan J. Smith
The Ford 7.3L “Godzilla” V8 has created quite a stir in the aftermarket performance world. Truck performance is incredible and swaps are taking place every day. It’s fantastic to see Ford Motor Company bring back a cam-in-block, pushrod V8, and the deal is sweetened by the large 445 cubic inch displacement.
Ford Performance began offering the Godzilla in crate fashion about a year ago, and now it released a hopped-up version dubbed “Megazilla” with 615 horsepower at 5,800 rpm and a whopping 640 ft-lbs. of torque at 3,600 rpm.
Megazilla makes power with CNC-ported and polished heads, 10.5:1 compression, an improved camshaft, plus a Ford Performance low-profile composite intake manifold with 93mm Shelby GT500 throttle body. Additionally, the engine gets Callies forged H-beam connecting rods, Mahle forged pistons and it comes with injectors and wiring. And if you like torque, this is the engine for you. “It produces over 500 ft-lbs. from 2,200 rpm all the way to 6,000 rpm,” said Mike Goodwin of Ford Performance.
The low-profile intake improves flow and angles the air inlet from an upward position to a straight position. And the heads are modified to improve flow. “We went with a mild street porting job, but we didn’t want to go too crazy. It’s making the numbers,” Goodwin added. “The power we got, 615, was with a conservative pump-gas tune and we know people will throw more camshaft and boost at it.
“One of the limiting things on the production engine is the pistons. They don’t have a lot of meat on the production pistons between the crown and the top ring. It’s also a cast piston and that’s fine for a truck that’s going to run at 4,000-5,000 rpm, but it’s not great in a performance application. So that’s one of the first things we decided to upgrade.” It also has Callies H-Beam rods and maintains the factory forged steel crankshaft. As for transmissions, Godzilla engines will accept Coyote or modular bellhousings and transmissions.
The engine also comes injectors and a factory engine harness that’s plug-and-play with the Ford Performance Controls Pak (manual or auto). Ford is targeting sub $20,000 for retail pricing.
