Moroso Ultra 40 Spark Plug Wires Red - SBC Chevy 350/383 Under Header HEI (Part 73686)

Time to wake up that small block Chevy!

These are the legendary Moroso Ultra 40 spark plug wires, part number 73686.

They're the bright red ones, so they'll look killer on your motor, but more importantly, they perform.

These are specifically made for Gen 1 SBCs (think 350, 383) with HEI distributors, and they're designed to route nicely under headers—no melting or burning here.

They're 8.65mm silicone wires, so they handle heat and deliver a strong spark.

It's a full performance set, brand new in the box with the Moroso warranty.

Whether you're building a hot rod or just maintaining your classic Chevy, these Ultra 40 wires are a solid upgrade.
