ZZ9 with ATI Well a guy I know is just pretty much giving away a zz9 cam for a lt1. So me being the cheap person that I am is really thinking about picking it up just for a few extra ponies. The reason Im considering this is that I dont know how long my stock internalled block will run so I want just throw a genaric cam in this motor and when its time to get a 396 get the custom grind. Here is the info on the cam.
ZZ-9 HydraulicRoller:
Intake Exhaust Advertised duration 282 287
Duration at .050 212 226
Gross lift .483 .520
Lobe separation 112
Here is the math that I did with 1.6 RRs
212/226 @.050, 112 lsa, .510/.550 lift on a 1.6 rr
I know the HP gains arent going to be as much as a custom grind but what kind of HP should I be looking at with stock heads? Also does anyone have a sound clip of the cam?
Let me know your opinions.

Versus a stock 96 Z/28 camshaft?
I would think that your overal numbers would pick up. You would be going to 212/226//112, so overall would pick up but the peak might not be as high as it would be on a 114. I'm not expert enough to say what the difference would be vs a 112 vs a 114, but it could be minor. I would say go for if it's free.
