It mounts inside the distributor cap and rotates with the distributor shaft, directing high-voltage current from the coil to each spark plug terminal in firing order. As a tune-up wear item, the rotor is typically replaced alongside the contact set, condenser, and distributor cap to restore reliable spark delivery and smooth engine performance.\u003c\/p\u003e\u003cp\u003eThis rotor is the correct replacement for the 18-5403 position in three GM-based marine engine applications: 6-cylinder 3.8L engines using distributor No. IBM-7014A, and 8-cylinder 305, 350, and 454 cid engines using distributor No. IBM-7011 or IBM-7013. Always match the rotor to the correct distributor number for your engine to ensure proper fit and ignition timing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e EMP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 300-00530\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Chrysler Inboard Tune Up Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Distributor Rotor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Reference Number:\u003c\/strong\u003e 18-5403\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCylinder Configurations:\u003c\/strong\u003e 6-cylinder, 8-cylinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engines:\u003c\/strong\u003e 3.8L, 305 cid, 350 cid, 454 cid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Distributor Numbers:\u003c\/strong\u003e IBM-7014A, IBM-7011, IBM-7013\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.033 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 840080402574\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1984-88: 6-cylinder 3.8L engines, distributor No. IBM-7014A\u003c\/li\u003e\n\u003cli\u003e1976-82: 8-cylinder 305, 350, and 454 cid engines, distributor No. IBM-7011\u003c\/li\u003e\n\u003cli\u003e1983-88: 8-cylinder 305, 350, and 454 cid engines, distributor No. IBM-7013\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e18-5403\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the EMP 300-00530 rotor used for?\u003c\/strong\u003e The EMP 300-00530 is a distributor rotor that directs high-voltage current from the ignition coil to each spark plug terminal in firing order as part of a marine inboard ignition tune-up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich engines does the 300-00530 rotor fit?\u003c\/strong\u003e It fits 6-cylinder 3.8L engines using distributor No. IBM-7014A, and 8-cylinder 305, 350, and 454 cid engines using distributor No. IBM-7011 or IBM-7013.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the EMP 300-00530 the same as rotor 18-5403?\u003c\/strong\u003e Yes, the EMP 300-00530 cross-references to rotor number 18-5403 for the listed GM-based marine engine applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this rotor weigh?\u003c\/strong\u003e The EMP 300-00530 rotor weighs 0.033 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the EMP 300-00530 rotor?\u003c\/strong\u003e The UPC for the EMP 300-00530 distributor rotor is 840080402574.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to replace other ignition parts along with this rotor?\u003c\/strong\u003e During a tune-up, the 300-00530 rotor is typically replaced together with the contact set, condenser, and distributor cap to restore reliable ignition performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich distributor number should I check before ordering?\u003c\/strong\u003e Confirm your engine's distributor number matches IBM-7014A, IBM-7011, or IBM-7013 before ordering the 300-00530 rotor, since each corresponds to a specific engine application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 300-00530 rotor fit both 6-cylinder and 8-cylinder engines?\u003c\/strong\u003e Yes, the same 300-00530 rotor is used across 6-cylinder 3.8L engines and 8-cylinder 305, 350, and 454 cid engines, provided the distributor number matches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this rotor for a Chrysler marine engine?\u003c\/strong\u003e The EMP 300-00530 rotor is cataloged under Chrysler inboard tune-up parts and fits the GM-based 3.8L, 305, 350, and 454 cid engine distributors listed for these applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the 300-00530 rotor for 305, 350, and 454 cid engines interchangeably?\u003c\/strong\u003e Yes, the same 300-00530 rotor applies to 305, 350, and 454 cid 8-cylinder engines as long as the distributor number is IBM-7011 or IBM-7013.\u003c\/p\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":48991284330715,"sku":"EMP-300-00530","price":7.92,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/EMP-300-00530-MerCruiser-Volvo-Rotor__75783.1722510930.500.750.jpg?v=1785329102","url":"https:\/\/www.goodvibesmarina.com\/products\/distributor-rotor-18-5403-for-chrysler-inboard-305-350-454-v8-3-8l-v6-1976-1988-mpn-300-00530","provider":"Good Vibes Marina","version":"1.0","type":"link"}
