i thought members would certainly benefit from this information....LSR cams are modern, aggressive cam lobe profiles - more aggressive than the XFI cams. They also have a new double spring specifically for these cams. duration split is crazy on some of these.... enjoy!!

nice grinds, but looks like most grinds are meant to be used with aftermarket/worked heads to take advantage of it...
