8. A big engine needs plenty of camshaft, so we stepped up to a custom hydraulic roller from Crane Cams. Not wanting to run a solid roller and deal with the extra expense of an adjustable valve train, we installed a sizable Crane hydraulic roller profile that offered 0.661 lift, a 260/276 duration split and a 114-degree lobe separation angle. Crane now offers a wide variety of different performance products for the LS engine family, including cams, rockers, pushrods and timing chains.
