Description

Dominate the drag strip and pro-street events with the raw carbureted power of the Roush BD427RC 427 R. This 7.0L small block utilizes a tall-deck 9.5-inch Dart Iron Eagle block packed with a forged 4.000-inch stroker crank to generate an aggressive 550 HP. Topped with high-flowing CNC-ported aluminum heads and a single-plane Victor intake manifold, this race-spec engine moves massive atmospheric volume to deliver brutal high-RPM pulls across the finish line.
