Cam question for the experts I am looking at a comp cam for my ls1. My engine has CAI, P&P throttle body, emissions removed, off road long tube headers with a 4" collector and x pipe, and the engine has been tuned. The cam i am looking at has 246 intake, 254 exhaust .613/.254 112 LSA. With this be a decent cam? I am looking for a little rumble with the idle but its also a DD and i am not into drag racing, more into auto cross events.
I'm guessing you meant .654 on the exhaust side?
Correct me if I'm wrong, but isn't that cam too big for a 346ci motor?
If not, it's still ridiculously big for a dd imo...

OP, if you want a cam that will work for you, don't just look for big numbers and think that's the best setup. There's a wealth of knowledge available on this board and a million cam threads, go to the search feature and read, read, read.
As I, and others have said, that cam is ridiculous, and I doubt it will have adequate piston to valve clearance. For an Auto-X'er you're going to want a more broad powerband, great valve control, and something far less peaky... I'd suggest you contact Geoff at EPS, his cams are not huge and have delivered for just about everyone running them. Valve control characteristics are superb and the powerband is very broad.
