LQ4 70 Firebird conversion questions

I bought a LQ4 out of a 04 Denali and I got LS3 heads intake and injectors from 2010 Corvette. I need a bigger throttle body will the computer from the Denali work with a cable throttle body or will I need a different computer. I have a t56 six speed from a 2001 Trans am. Looking for suggestions on a cam. I plan on milling the heads .020 to .030. I want something that drives good on the street and makes around 500hp. I'm looking at Texas Speed ls3 225/230 .617/612 or 229/236 .624/615. Any suggestions?
Thanks Mike

Second cam is what I'd run. I think you can tune out the DBW but not 100% positive.

1st one would work....but you'd probably enjoy the 2nd one more, as long as no ptv issues.

If its the same pcm I got with my lq4 dbw is the only option without swapping pcm for another style. You can get the number off the sticker on the pcm and look it up they have a list on this site of which ones can and which ons cannot.

I was leaning toward the second one too but after reading the post on l92 heads I'm confused. I have to get the number off the pcm and check if it can be turned off.
Thanks Mike
