The 331 SRXE ROUSH Crate Engines stay true to the time-tested designs that shaped performance in the 1960s and beyond. At the same time, modern components and precision machining dramatically increase their output. Compared to original production engines, these crate engines generate substantially more horsepower and torque. Because of that added strength, they respond differently under throttle and load. The character feels classic, yet the performance is far more aggressive. In short, you get heritage-inspired engineering with power built for today’s standards.
