It made more power in back-to-back testing compared to a similarly spec鈥檇 cams from other leading cam companies.  \u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan\u003e This cam generally runs in the 5.30's-5.50's in the 1\/8 mile in a 3000+ lb chassis and has run as fast as 5.10'-5.20's using the same TFS 245 heads. Since this cam utilizes ultra stable lobes, it will turn 7500 rpm with our Platinum dual springs (SK001\/SP001). Using our .685\" lift springs (SP010-16) shimmed to 1.700\" allows it to turn 8000 rpm. For 7500+rpm combos, Johnson short travel lifters and stock rocker bodies should be used.  \u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan\u003e Roller rockers will NOT turn as much RPM as the stock rockers will due to additional weight. Most cam gurus claim .595\" isn't enough lift for a nitrous cam, but back to back testing has shown otherwise, with increased exhaust lift showing no gains in power. This cam has gained 400 rwhp on a 300 shot of nitrous utilizing TFS 245 heads with the N2O exhaust port.  \u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan\u003e VVT engines will require a VVT conversion kit If installing in an engine originally equipped with a 1-bolt camshaft, a 3 bolt conversion kit will be required  \u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Loading EDP related metadata --\u003e\u003cspan\u003e\u003c\/span\u003e \u003ca\u003e  \u003c\/a\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"My Store","offers":[{"title":"Camshaft Only","offer_id":48692020936898,"sku":"610298445416235013-16975282-16754876-65925368-0-0-0-0","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Cam, Spring Set (Titanium Retainers), Pushrods","offer_id":48692020969666,"sku":"610298445416235013-16975282-16754876-65925369-0-0-0-0","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Cam, Spring Set (Steel Retainers), Pushrods","offer_id":48692021002434,"sku":"610298445416235013-16975282-16754876-65925370-0-0-0-0","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/6084\/1410\/files\/2D7BA0EF-1C13-5B85-B4BF-845D91C4C4CC.jpg?v=1787882943","url":"https:\/\/viuagrello.shop\/products\/btr-brian-tooley-racing-400-nitrous-camshaft-v2-for-gen-3-4-ls-x4380","provider":"My Store","version":"1.0","type":"link"}
