These are regrinds on your stock cams, turn around time is about 2 weeks. Dyno testing has shown over 14 hp increase without any loss on the lower rpms. The curve follows the stock hp up to 4000 rpms and then begins to climb all the way to redline. ( Stock cams typically fall off after 5800 rpms.) 264 duration cams with 330 lift and increased overlap make for a slightly lopey idle.
