The “BFD” cam is engineered to give your naturally aspirated LS the MOST SAVAGE CHOP humanly possible while delivering big power throughout the curve. Ground on a 108 LSA, this cam has enough chop and grunt to register readings on the Richter scale! Our BFD Line of camshafts is the nastiest sounding cam you can stuff into your 5.3, 5.7, 6.0, 6.2, LS7, or Big Inch Stroker LS. Can be ran in 5.7's and 6.0's as well!
