Be careful with the "off the shelf" LS1 cams. Especially the big ones. The ramp rates on the lobes are brutally fast and will eat your valvetrain alive. There are only 2 cams designed for the LS1 that were meant for road race use. The ASA cam and the Grand Am Cup cam. You wont see the peak #'s with these cams like you do with the others, what you will see is oodles of power "under the curve". Most Ls1 cams are "peaky". These ones are not. They both have big duration, narrow LSA and decent lift. I dont know about he ASA cam but the GAC has an asymetrical lobe profile. Alot softer on the valve train.
