ok guys....I'm been scouring the net for a few days now and cannot find this information anywhere! I need to know when the valve events happen. I know the duration, lift, and LSA, as just about every site that comes up with Google has that information. However, this information is basically useless on its own. To actually know a cam you also need to know where the intake centerline is. With this ONE other piece of information I can get the valve events and be able to time my injector pulse accordingly. If anyone has them, the seat-to-seat duration (as opposed to at .05" lift) would also be nice as I can calculate ramp rates from that.

Thanks in advance.

Is this it?

"The ?98-2000 LS1 Camaro hydraulic roller cam uses a 122-degree intake centerline
combined with a 117-degree exhaust centerline to create a 119.5-degree lobe separation angle.
This combines with intake/exhaust duration numbers of 201/212 degrees at 0.050-inch tappet lift."

Thanks. I guess these numbers could be correct although they look extremely conservative! I guess I'm just used to lots of overlap.
