• Brian Tooley BTR 400+ cubic inch Nitrous Camshaft V2 Specs: 247/27x .618"/.618" 112LSA 3 Bolt Pattern
• This camshaft is the result of years of back to back testing on 400+ cubic inch engines, mostly using TFS cathedral port heads. It made more power in back-to-back testing compared to a similarly spec鈥檇 cams from other leading cam companies.
• 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.
• 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.
• 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
