Moroso Chevrolet Big Block Ignition Wire Set - Ultra 40 - Unsleeved - Non-HEI - Crab Cap - Black

If you're working on a Chevrolet big block engine and need to replace the spark plug wires on a non-HEI distributor with a crab-style cap, this Moroso Ultra 40 set is a solid option. These wires are designed to handle the demands of a performance ignition system, ensuring a strong spark gets to your plugs.

Moroso uses a 40-ohm resistance wire core, which helps reduce radio frequency interference while still allowing for a robust spark. The unsleeved design means the wires are direct and clean-looking in the engine bay, and they're built to fit the specific non-HEI crab cap style distributor common on many older Chevy big blocks. This set is a direct replacement, making installation straightforward if you're already familiar with your ignition system.
