This JDMSPEED HEI distributor cap and rotor kit is aimed at classic Chevy owners, hot-rodders and anyone maintaining or restoring small-block and big-block V8s that use K549-style HEI distributors. It suits DIY mechanics, professional shops and performance builders who want a robust, visually distinct replacement cap with reliable brass terminals and a matching red coil cover. Avoid using the kit if your vehicle requires a different distributor form factor — check fitment before purchase to ensure compatibility.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this cap fit my 350 Chevy HEI distributor?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it's designed for K549-style HEI distributors commonly used with 350 SBC engines, but confirm your distributor uses the same mounting and terminal layout.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the kit include the rotor and coil cover?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the package contains a distributor cap, rotor and matching red coil cover for a complete HEI replacement.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"JDMSPEED","offers":[{"title":"Default Title","offer_id":67591111999673,"sku":"B0DRCP63DJ","price":62.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/jdmspeed-cap-front-view_fd21cb05-c01c-4254-814a-ac17dbaabd5e.jpg?v=1790541574","url":"https:\/\/redleafauto.ca\/products\/jdmspeed-hei-distributor-cap-rotor-kit-red-k549-fits-chevy-sbc-bbc-brass-terminals","provider":"Redleaf Auto","version":"1.0","type":"link"}
