BTR GEN V STAGE 4 TURBO CAMSHAFT (3 BOLT) - BTR-GENVSTG4TURBO3BLT 38% FUEL LOBE 227 DEG INT - 24x EXH DEG 113 LSA .638" INT .643" EXH. BTR is proud to introduce these new editions to our already impressive lineup of Gen V camshafts. The new Gen V Turbo Stage 4  cam was designed to bridge the gap between street and strip applications. This camshaft is an excellent choice for higher-effort L83s and more aggressive LT 6.2s utilizing a wide range of different turbos.  Recommended for use with a single  S485 - S494mm or small twin 66mm - 72mm turbos. This camshaft offers an aggressive idle with great midrange and top-end capabilities. Unlike other kits that require expensive aftermarket cam cores and timing covers to eliminate the VVT phaser & solenoid, we designed this kit to allow the use of a special cam sensor designed to work with the OEM timing cover available in our 3 BOLT VVT LOCKOUT KIT , which allows you to use this specially machined 3 bolt Gen V camshaft with an LS3 cam gear and retain the factory Gen V VVT front cover. Stock ECUs will have limitations, see cam card. Some wire connector trimming is required; see instructions. - The use of BTR dual spring kits is required. We also recommend the use of hardened pushrods in power adder applications. - Requires the use of an aftermarket converter for best drivability and acceleration. - Includes a +38% fuel lobe.
