The MSD IGNITION Big Block Ford Plug Wire Set (MSD 31389) is designed for serious engine builders and performance mechanics working with both classic and modern big block Ford applications. This complete wire set is ideal for restoring muscle cars, upgrading street rods, or tuning high-output engines, effectively replacing the weak points of OEM ignition wiring.
Engineered to handle increased spark voltage and demanding combustion environments, these wires ensure reliable spark delivery under sustained load and elevated RPM conditions. The proprietary core material and shielded construction minimize electromagnetic interference and cross-firing, which are critical factors for high-output ignition systems. Additionally, the wires feature superior insulation that resists heat, oil, and ozone degradation, maintaining consistent resistance for balanced cylinder firing.
Mechanics upgrading from deteriorated factory wiring or installing aftermarket ignition control systems will notice immediate improvements in cold starts, idle quality, and sustained acceleration. This complete set fits big block Ford engines commonly found in Thunderbirds, Torinos, Cougars, and high-performance truck builds from the 1960s through early 1980s, making it a versatile choice for various applications.
