It's also replacement parts for P-Series and SH-Series engines. Since this kit and includes 1984-'99 style hydraulic lifters,the larger late style roller diameter requires that cams designed for 1984-'99 models must be used to achieve correct valve timing. When choosing a late style cam for this type of engine, be aware that, due to the approximate 1.5:1 rocker ratio of most aftermarket rocker arms for shovelheads, the total valve lift will be reduced by about 9 percent from the specified value.","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":44400908665006,"sku":"SSC106-6027","price":254.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/0714\/9486\/files\/9e76e071ed1c4580655faaa6ba50e19a_f0af7c89-691f-4200-9289-dd75129aaf5f.png?v=1702143666","url":"https:\/\/purauto.com\/products\/s-s-cycle-3-4-20-unef-3b-x-233in-black-steel-4140-nut-hh","provider":"PurAuto","version":"1.0","type":"link"}
