Little Green Machine Sports 750-HP and 470 Pounds-Feet of Torque
The SB4 has the color green but that does not mean that it is eco-friendly. It just means that the engine is green in color. What it does not lack is power. The vehicle has 750-HP and 470 pounds-feet of torque. It is also based on the LS7 engine.

Quote: "By ripping out everything down to the block and rebuilding it as a dual overhead cam wonder, Mercury Racing managed to pull a stunning out of the 7.0-liter engine now known as the SB4, while lifting the redline to a stunning 8,000 rpm." (Courtney, 2017)
