BTR Gen V Twin Screw Camshaft For L83 Engines Using Stock Converter

Introducing the new BTR L83 Twin Screw STOCK STALL camshaft for use in Twin Screw supercharger applications. This camshaft works well with factory type LT4, and up to TVS2300 / Whipple 3.0L style superchargers. Designed to help your boosted factory L83 truck engine make more power and torque everywhere in the curve compared to the OEM cam, while still allowing the use of the factory torque converter. This cam delivers a mild lope sound at idle and good driveability. Developed in house, these new BTR lobe designs were Spintron tested to help maintain strict valvetrain stability and durability standard at higher rpm.

Note: The use of aftermarket .660 lift springs is required. E85 fuel is highly recommended. Designed to be used with a locked out phaser limiter.
