Moroso Ultra 40 ignition wire set for Chevrolet big‑block engines in non‑HEI layout. This unsleeved, under‑header black kit is configured for routing beneath headers on traditional distributor setups and supplies the wire lengths and terminations matched to big‑block Chevy geometry. It’s a practical replacement when non‑HEI firing systems require under‑header routing and no sleeve protection.
