{"product_id":"track-1-aluminum-cylinder-head","title":"Track 1 Aluminum Cylinder Head","description":"The BRODIX Track 1® aluminum cylinder head is engineered for racers seeking enhanced horsepower in drag or oval track applications. This head boasts a 221 cc intake port volume and a 64 cc combustion chamber, contributing to improved engine performance. Constructed from A-356 virgin aluminum alloy, it is designed to be lighter than traditional cast iron heads.\n\nKey specifications include 2.080\" intake valves and 1.600\" exhaust valves, with a maximum lift capability of .700\". The Track 1® features a nitrous-friendly, thick deck surface and comes equipped with phosphorous bronze valve guides and hardened ductile iron valve seats suitable for unleaded fuel. The spring pockets are designed to accommodate up to a 1.550\" valve spring. The exhaust ports are configured to accommodate a standard Chevy pattern.\n\nThis assembled cylinder head is part of the Track 1 series, known for delivering significant horsepower gains. While the standard Track 1 offers robust performance, the Track 1X variant is noted to provide an additional 20-25 horsepower out-of-the-box due to improvements like 40\/60 valve spacing and CNC-machined combustion chambers. The BRODIX Track 1® is also available in a completely CNC ported version for maximum consistency, with no special components required for installation.","brand":"Brodix","offers":[{"title":"Default Title","offer_id":52687276376376,"sku":"1001008A","price":2463.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661173905.jpg?v=1784882120","url":"https:\/\/store.motormia.co\/products\/track-1-aluminum-cylinder-head","provider":"MOTORMIA","version":"1.0","type":"link"}
