V-Thunder Cam BT70-77 In/E 242/242

These camshafts from V-Thunder provide the ultimate in arm stretching power on the street or in competition. Power proven and backed by hundreds of exhaustive hours on the dyno and in on-bike testing, these cams provide added punch at all levels of performance for Shovelhead motors, while maintaining the longevity and integrity of the valve train parts. Cams that need a Hi-Performance carburetor were found to give the best performance with the Mikuni's HRS42 carburetor. V-Thunder cams are made with SAE 6150 bearing, quality steel and induction hardened for optimum surface longevity. Tolerances are extremely precise with the aid of our computer controlled machining centers. The cams are made in the USA and come with complete installation instructions.
