Long factory runners and a restrictive plenum limit volumetric efficiency in forced induction or aggressive cam setups. Additionally, the stock composite material is susceptible to cracking under high boost. Factory fuel rails also struggle to deliver adequate volume for larger injectors, limiting potential on high-horsepower F-Body builds.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from cast aluminum with a black finish, this single-plane manifold targets cathedral port LS1, LS2, and LS6 heads. Utilizing a 4150 square bore base and a 5.417-inch intake height, it straightens the runner path (2.50\" H x 1.15\" W port size) to drastically increase high-RPM plenum volume. This shifts the powerband into the 2500-7000 RPM range, making it ideal for large EFI throttle bodies or carbureted conversions. Included extruded aluminum fuel rails and heavy-duty mounting hardware ensure consistent fueling, eliminating the mechanical bottlenecks of the factory plastic unit.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1998-2002 Chevrolet Camaro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eLS1 \/ F-Body\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e305-325 hp \/ 335-350 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1998-2002 Chevrolet Camaro (5.7L LS1 V8)\u003c\/li\u003e\n\u003cli\u003eGM LS1 Engines (Cathedral Port)\u003c\/li\u003e\n\u003cli\u003eGM LS2 Engines (Cathedral Port)\u003c\/li\u003e\n\u003cli\u003eGM LS6 Engines (Cathedral Port)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Chevrolet Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eFor modern muscle car and F-Body builds, upgrading to a cast aluminum single-plane manifold ensures the structural integrity to handle boost and the airflow dynamics necessary to support high-horsepower LS powerplants.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48204773720312,"sku":"DS-E80JK73NW","price":289.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/intake-manifold-for-chevrolet-camaro-1998-2002-cathedral-port-black-w-fuel-rail-efi-1.webp?v=1775581290","url":"https:\/\/performancechiptuning.com\/products\/intake-manifold-for-chevrolet-camaro-1998-2002-cathedral-port-black-w-fuel-rail-efi","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
