Moroso Chevrolet Small Block (Sprint Car) Ignition Wire Set - Ultra 40 - Unsleeved - HEI - Blue

If you're building a Chevrolet small block for a sprint car and need a reliable ignition wire set, this Moroso Ultra 40 set is a solid option. Designed for HEI distributors, these wires are built to handle the demands of high-performance racing engines. The unsleeved construction helps ensure maximum spark energy gets to your plugs, which is critical for consistent power delivery on the track.

Moroso uses their Ultra 40 wire, which features a low resistance of only 40 ohms per foot. This helps the ignition system deliver a strong, hot spark to the combustion chamber. The blue color adds a clean look under the hood, and the set is specifically configured for Chevrolet small block engines using HEI ignition. This means they're made to fit right and function as expected in that application.
