Generally speaking...the higher the duration the higher it will want to push your Tq peak and HP peak in the rpm band. This may result in a rough idle and drivability issues in the lower rpm. Like bucking in 5th gaer at 1200 rpm and possible stalling at idle. Tuning can help alot of this so can getting the cam on a 114 lsa. It also depends on how much you are willing to live with on a daily basis. Could you daily drive a car with that cam...you bet. Would you get sick of it....that depends on your preferences.

Lift is another issue completely. Huge lift cams greatly reduce spring life. If you get a cam with a valve lift approaching .600...I would recomend changing springs yearly if you put a normal amount of driving miles on them. Bur stepping down a bit to something in the .560-.580 range makes a very big difference in longevity with minimal loss of power.

I also dont like the reverse split (intake duration larger that exhaust) for the LS1s. Especially if you are going to spray at some point. That cam you listed would idle like absolute ass

What are you goals for the car? What kind of idle are you looking for? Will you race the car? Where do you want the HP to peak in rpms?
