TPIS cam question

I am getting ready to install a TPIS zz9 cam on my lt1 soon. I dont know much about it i picked it up for free so i had to take it. I was just wondering how it performs and stuff. I think its pretty mild but thats ok better than stock and its a daily driver.

Intake Exhaust
Advertised Duration 282 287
Duration at .050 212 226
Gross Lift .483 .520
Lobe Separation 112

Mainly i just wanted a guess on power and also how rough or smooth it idles. I cant find anyone who knows too much about it so any help at all would be great. Thanks

From what I have heard it is a GM performance parts ZZ4 cam with faster ramp rates. The ZZ4 cam is the one in the 350hp crate motor, also Ive heard its a low-mid type torquey cam good for TPI style intakes. I run the ZZ4 cam but couldnt tell you ETs because my trans is being a POS!
