gpxtuning@gmail.com and tell him I referred you along with your list of mods and he'll spec you a cam. Same price as anywhere else and takes the guess work out for you. If you're on IG look up @gptuning and listen for yourself.
I will tell you that your "lopiness" will be limited without a stall and headers. And just doing a cam for sound is retarded. People WILL try to run you from time to time and if you don't see my point now, you will after you continue to lose.
Typically, it's $425 for cam shipped to you and about $1100 for cam and BTR cam kit shipped. I would also suggest doing the Melling oil pump while you're there $120 PN 10295, and you can either choose a GM timing chain or the Katech C5R chain for $100 more. Plan to do cam, oil pump, chain, PR's, springs, and trunion upgrade which is all included in the kit.
