Should run in the 5.30's-5.50's range in the 1\/8 mile in a 3000+ lb chassis and has run as fast as a 5.10 1\/8 mile pass using the same dyno-tested TFS 245 heads and a Mast intake.\u003c\/span\u003e\u003c\/p\u003e \u003cp style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: 16px;\"\u003eSince this cam utilizes engine dyno and Spintron tested stable BTR in house developed cam lobes, it can turn 7500 rpm with our SP010 .685\" lift springs (SK702) when using sub 105 gram valves. Use of our .685\"  (SK703) kit when shimmed to 1.700\", allows it to turn 8000 rpm assuming lightweight valves (sub-105-gram) and OE rocker arms. Roller rockers will NOT turn as many RPMs as the stock rockers will due to additional weight.  Good lifters should be used like the Johnson short\/limited travel type or similar. Very aggressive idle. \u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003ctable class=\"data table additional-attributes\" id=\"product-attribute-specs-table\"\u003e  \u003ctbody\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eEMS Code\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"EMS Code\"\u003eEMS: Code 3\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eBTR SKU\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"BTR SKU\"\u003eBTR-400+NITROUS\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eLength\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Length\"\u003e24.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eWidth\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Width\"\u003e3.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eHeight\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Height\"\u003e3.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eWeight\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Weight\"\u003e15.000000\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eBrand\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Brand\"\u003eBrian Tooley Racing\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003ePart Type\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Part Type\"\u003eCamshaft\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eEngine Type\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Engine Type\"\u003eGen III\/Gen IV LS\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eEngine Combination\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Engine Combination\"\u003eNITROUS\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eCamshaft Style\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Camshaft Style\"\u003eHYDRAULIC ROLLER\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth class=\"col label\" scope=\"row\"\u003eCam Bolt Style\u003c\/th\u003e \u003ctd class=\"col data\" data-th=\"Cam Bolt Style\"\u003eTHREE BOLT\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e","brand":"BTR - Brian Tooley Racing","offers":[{"title":"Default Title","offer_id":62809095700639,"sku":"BTR-400+NITROUS","price":409.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0424\/7571\/6767\/files\/btr-lsx-hero_29.jpg?v=1780753535","url":"https:\/\/streetdrivenperformance.com\/products\/btr-400-ls-nitrous-camshaft-v2-btr-400-nitrous","provider":"Street Driven Performance","version":"1.0","type":"link"}
