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

If you're working on a Chevrolet big block engine with an HEI distributor and need a new set of spark plug wires, this Moroso Ultra 40 set is a solid option. These wires are designed to handle the demands of high-performance ignition systems, ensuring a strong spark gets to your spark plugs for efficient combustion. The unsleeved design means the wires are exposed, which can be beneficial for routing in tight engine bays or for a specific look, but it also means they're more susceptible to heat and abrasion than sleeved wires.

Moroso built these wires with a 40-ohm resistance per foot, which is a popular choice for performance applications as it helps reduce radio frequency interference while still allowing for a strong spark. The red color offers a clean, classic look under the hood, and they're specifically made to fit HEI distributors with a crab-style cap. This means they should route and connect correctly without a lot of fuss, assuming your distributor is set up as intended.

When installing these, take your time to route them away from hot exhaust manifolds or headers to prevent premature damage, especially since they are unsleeved. Proper routing is key to their longevity and performance. This set is a direct replacement for your existing wires, making the job straightforward if you're comfortable working around your engine's ignition system.
