Engine Camshaft-thumpr(tm) Comp Cams 54-600-11 on 2040-parts.com

Im selling a Comp Cams Thumpr 54-600-11 cam that cam out of a 02 Vortec 5.3.  Hydraulic Roller Tappet, Advertised Duration 275/295, Lift .553/.536.  This cam was installed by previous owner but has not been ran so it is as new. I did not know that this motor had this cam or I would have keep it but once I removed it and discovered what it was I had already purchased a custom one with no returns so my loss your gain. It will fit the following: GM LS Gen III/IV 8 Cyl. '97-Current Three-Bolt 4.8/5.3/5.7/6.0/6.2/7.0L Engines.  
              Thumpr Series cam and lifter kits, a line of cutting-edge hydraulic roller camshafts for engines originally equipped with flat tappet cams. You can expect a substantial power increase without sacrificing reliability or ease of maintenance! The lobe profile and grind characteristics of new Thumpr cams include blending an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap. This maximizes rough-idling tendencies, delivering a seriously aggressive exhaust note without impacting engine power output. Thumpr camshafts are available in a variety of grind profiles, each producing impressive horsepower and torque performance within a different rpm range.
