The Moroso Ultra 40 ignition wire set for Chevrolet small block engines is an unsleeved non-HEI under-header kit finished in blue, configured to route beneath the headers where required. It matches small block plug and distributor styles that use non-HEI connectors and provides the boot angles and lengths needed for clean fitment in under-header installations on compatible Chevrolet small block engines.
