BTR 400+ LS Nitrous Camshaft V2. Sold as described below; installation labor and tuning are not included.
Since 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.
