Ultra 40 Plug Wire Set BBC Over V/C HEI Black

The Ultra 40 Plug Wire Set BBC Over V/C HEI Black from Moroso is designed to provide the ignition reliability that big-block Chevy engines require. This wire set is particularly beneficial for applications with over-the-valve-cover header clearance, making it ideal for street machines, race builds, and restorations where standard wire routing is insufficient.

Engineered specifically for BBC applications running HEI distributors, the Ultra 40 construction emphasizes signal clarity and heat resistance. The 8mm black wire jacket is designed to withstand the harsh conditions under the hood, while the internal conductor ensures low resistance throughout the ignition cycle. The "over V/C" designation indicates that these wires are pre-formed to clear valve covers and exhaust headers without kinking or touching hot surfaces.

Mechanics and engine builders working on BBC platforms, such as the 454, 427, or 396 displacement, will find the pre-contoured routing saves significant installation time. Each wire is equipped with HEI-compatible boots and connections that fit securely in the distributor cap and spark plugs, ensuring a reliable ignition system for high-performance applications.
