BTR recommends its BTR-SK018 or SP011-16 valve springs with this camshaft, particularly for 6.0L or 6.2L truck engines with square-port heads. Recommended lifters are LS7-style X12499225 units with BTR95365-4 lifter trays, and the suggested pushrod length is 7.400 inches. This camshaft works with factory (OE) torque converters.
In BTR's in-house dyno testing on a stock GEN IV 5.3L short block, the Stage 2 V3 produced peak-to-peak gains of roughly 53 horsepower and 24 lb-ft of torque over a stock 5.3L truck camshaft, with average gains near 12 horsepower and 16 lb-ft between 1900-5000 RPM.
