The 427 R ROUSH crate engines carry the DNA of the iconic engine designs first produced in the 1960s and later. However, today’s crate engine technology delivers far greater horsepower and torque than those original production engines ever could. As a result, these modern ROUSH engines develop power more aggressively and perform differently under real-world driving conditions. The foundation stays rooted in classic engineering. Yet the output and capability reflect a completely updated level of performance.
