Roush Performance Crate Engines Now Available at Summit Racing

Nobody knows how to get more horsepower out of a Ford engine than Roush Performance. It’s been the case ever since founder Jack Roush was building hot Fords for the famous Gapp and Roush Pro Stock team back in the 1970s.

Roush uses its drag race, road course, and NASCAR engine experience to build its small block, FE, and 429/460 big block crate engines. All Roush crate engines are dyno-tested and guaranteed to make within 2% of the advertised horsepower ratings.

Summit Racing carries 108 versions of Roush Performance crate engines in several series. All are fully assembled with intake, distributor, plug wires, air cleaner and valve covers, water pump, and alternator (most versions).
