{"product_id":"performer-rpm-power-package-top-end-kit","title":"Performer RPM Power Package Top End Kit","description":"The Edelbrock 2087 Performer RPM Power Package Top End Kit is designed to provide an all-in-one solution for enhancing the performance of 1968-1979 Big-Block Chrysler 440 V-8 engines. This comprehensive kit brings together dyno-matched components, including assembled cast aluminum cylinder heads with 84cc combustion chambers, a camshaft, a dual-plane intake manifold, lifters, a timing set, and all necessary gaskets and hardware for installation.\n\nThe cylinder heads feature 2.140-inch intake valves and 1.810-inch exhaust valves, designed to improve performance throughout the RPM range for enhanced throttle response and top-end horsepower.\n\nInstallation requires careful attention to detail. The manufacturer advises using RTV sealant for end seals, not gasket seals, and applying sealant to intake bolt threads that extend into the lifter valley or coolant passages. Proper sealing of NPT\/pipe thread fittings with Teflon tape or paste is also recommended, with a caution against overtightening to prevent cracking the aluminum.\n\nThis kit produced 482 horsepower and 528 ft-lbs of torque on a 440 cubic inch engine with 9.27:1 compression, making it an ideal upgrade for enthusiasts seeking a substantial performance boost.","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":52687925117240,"sku":"EDL-2087","price":3237.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664195750.webp?v=1784887572","url":"https:\/\/store.motormia.co\/products\/performer-rpm-power-package-top-end-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
