The 5.3 Hot Rod cam is BTR's newest offering for the guys with 4.8 & 5.3 displacement truck engines. It is replacing the LS1/LS2 NA Stage 1 camshaft. This cam delivers an aggresive idle while maintaining good street manners. It makes slightly less torque down low than our Truck Norris cam yet produces an additional 20+ HP at peak. These newly designed BTR lobes were developed in house and tested on our Spintron and Engine Dyno to achieve the highest overall power curve while also maintaining our strict valvetrain stability and durability standards.
SPECS: 217/23X, .613/.607, 114 LSA
