Thanks to continued testing and research, BTR has updated their Stage 4 LS7 camshaft to this V2 version which makes even more power than the previous grind! This camshaft is very aggressive and should only be used in maximum effort combinations. This camshaft has knocked down 600whp in numerous cars with supporting modifications. It has a very aggressive idle and makes great top end power at the sacrifice of some low end torque.
