I'm eager for the LSxperts to chime in, as I think you have an issue with the cam position sensor. The LS9 is a gen 4, and you're posting in the gen 3 section.
I'm also wondering about the whole timing set / attachment-to-cam situation.
That's a really large cam for a little 4.8, even if you are adding boost. I'm guessing you got the cam really cheap, as a take out from a ZR1 guy who was upgrading?
Otherwise, the same money coulda got you something better.

Isolde- actually I posted in the right section because this is a specific question about this cam going into a gen iii engine. And regarding the cam sensor, I am aware that I need the ls2 timing cover, sensor, socket and to extend my cam sensor wire. These parts are ordered and on their way. Also, from what I've read this can is great with boosted engines. It really isn't that big honestly. And I got the cam for 55 bucks and everything I need for the swap including the cam came to 150 bucks. So I think I got a great deal for actually a really good turbo/blower cam

I just wasn't clear about the cam sensor, it's cool that you got it sorted.
LS9 cam is 211 / 230, on a 121 sep, right? 211 sounds small, but with that 230 exhaust and that 121 sep, your exh opening point, and your intake closing point, are closer to maybe a 234 / 234-112. I would bet it feels dead below 2500, and no better than stock until 3500? But if you're gonna use a 4400 stall and a 3.73 gear, then maybe that won't matter? I will be curious for your report about your first drive after dyno-tyning.
