Moroso Chevrolet Big Block Ignition Wire Set - Ultra 40 - Unsleeved - Non-HEI - Over Valve - Black

This is the Moroso Ultra 40 ignition wire set for Chevrolet big block engines that do not use an HEI distributor. These wires are designed to route over the valve covers, providing a clean look and proper clearance. The unsleeved construction means you get maximum spark energy transfer directly to your spark plugs.

Moroso builds these wire sets with their Ultra 40 wire, which is known for its low resistance. This helps ensure a strong spark, which is crucial for efficient combustion, especially in a big block engine. The black, unsleeved wires offer a classic, no-frills appearance that many builders prefer for a period-correct or minimalist engine bay. They are specifically made to fit over the valve covers, avoiding common routing issues.

When installing, pay attention to the routing to ensure the wires aren't rubbing against hot engine components. This set is a solid choice for anyone looking to replace worn-out wires or upgrade to a more direct spark delivery system on their non-HEI big block Chevy.
