Chrome – 1953–1965 Panhead; 1966–1984 Shovelhead\u003c\/h2\u003e\n\u003cp\u003eThis kit has a 3\/8\" lower seat for the pushrods; reducing the pushrod to tappet angle. Includes a set of two 7075-T651 chrome plated billet tappet blocks and a set of 4 large bore Powerglide big axle tappets. The tappets are JIMS Powerglide tappets that are custom extra wide; with a .761\" outside diameter. Therefore OEM .731\" diameter Powerglide tappets for stock Shovelhead are not interchangeable. Note: 53-E76 Pan \u0026amp; Shovel models will require a tappet guide bolt conversion kit; like 502990 Allen \/ 989173 Cap style \/ 513555 Acorn; that is correctly threaded for 53-E76 crankcases; so the bolt head will fit the flat L76-84 design of these JIMS tappet guides.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003e53-65 Panhead; 66-84 Shovelhead (NU)\u003c\/p\u003e\n\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Jims\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e MOTOR PARTS \u0026gt; TAPPET BLOCKS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit:\u003c\/strong\u003e KIT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e 961368\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePart Numbers\u003c\/h2\u003e\n\u003cp\u003eMCS Part Number: 961368\u003cbr\u003eManufacturer Part Number: 1029-53C\u003c\/p\u003e","brand":"JIMS","offers":[{"title":"Default Title","offer_id":57378858533251,"sku":"MCS961368","price":1369.05,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1329\/4265\/files\/961373k.jpg?v=1785974484","url":"https:\/\/hogparts.co.uk\/products\/mcs961368","provider":"Hogparts UK Ltd","version":"1.0","type":"link"}
