228/232 .629/.600 108 LSA Camshaft

The Texas Speed & Performance B.F.D. "Chop Monster" 5.3L Cathedral Cam (#25-TSPBFD-53) is engineered to deliver an aggressive "savage chop" exhaust note, characteristic of high-performance camshafts, while simultaneously enhancing power output across the RPM range. This cam is designed for naturally aspirated LS engines, including 5.3L, 6.0L, 6.2L, LS7, and big-inch stroker LS applications. With specific cam specifications of 228 degrees of intake duration and 232 degrees of exhaust duration, a lift of .629" on the intake and .600" on the exhaust, a 108 LSA (Lobe Separation Angle), and a 105 ICL (Intake Centerline), the "BFD" cam aims to maximize both sound and performance. One notable real-world application mentions achieving 545 horsepower and 475 lb-ft of torque at the wheels with this cam, paired with a 4L80E transmission, while still maintaining around 20 MPG on the highway. To properly install and operate this camshaft, a stall converter of 3600 RPM or higher is recommended. Additionally, upgraded valve springs, specifically dual .660" springs or better, are required to ensure reliable operation and prevent valve float at higher RPMs. This camshaft is sold as a cam-only product, and other supporting modifications may be necessary for optimal performance and longevity.
