The F4.6 V2 features a new crankcase and heatsink design with larger heatsink fins for improved cooling. This new design also makes the engine 37g lighter and 12mm shorter. A new pull start utilises a one-way bearing encased in a large 14mm hex for increased durability.

The F4.6 is the powerplant responsible for the immense speeds and raw torque in the Savage X 4.6, and is also available to fit into any Savage or big-block monster truck. It features 8-port race tuning, 2.9 horsepower, and a powerband reaching up to 32,000RPM. The composite 7.5mm carb is heat-resistant for consistent tuning as the engine warms up.
