Ford offers two powerful gas engines for its Super Duty lineup, the 6.8-liter Mini-Zilla and the 7.3-liter Godzilla. Both are cast-iron behemoths with pushrod architecture but differ in displacement, power output, and pricing.
Key Takeaways
- Ford’s 6.8L Mini-Zilla produces 405 hp and 445 lb-ft of torque for $1 less than the base model price.
- The 7.3L Godzilla boasts a more powerful output with 430 hp and 485 lb-ft, available as an upgrade option at $1,500 extra.
- Both engines feature similar architecture but vary in compression ratio and stroke length to optimize performance for different needs.
The Mini-Zilla is the standard engine across most Super Duty models due to its cost-effectiveness. It offers a solid 405 horsepower and 445 lb-ft of torque, making it an attractive option for those on a budget or who don’t need extreme towing capacity.
However, if you want more power, the Godzilla is your choice. With 25 more horsepower and 40 extra pound-feet of torque compared to its smaller sibling, this engine delivers when pulling heavy loads or climbing steep grades. Its higher cost reflects its superior performance capabilities.
The engines share a cast-iron block design but differ in their internal configurations. The Mini-Zilla has a shorter stroke length at 3.68 inches versus the Godzilla’s longer 4-inch stroke, contributing to its lower displacement despite similar bore sizes. This affects compression ratios too; the Mini-Zilla runs at 10.8:1 while the Godzilla operates slightly less compressed at 10.5:1.
Compared to competitors like GM and Ram, Ford’s engines stand out for their pushrod design which is rare in modern trucks but appreciated by enthusiasts who value this traditional tech. Both engines compete with diesel options that offer more torque but come with higher costs and maintenance requirements.
Frequently Asked Questions
