Critique and help my build I currently have an 04 5.7liter GTO motor. It has a vrx4 cam, patriot stg 3 heads, arp head bolts, arp main studs, arp rod bolts. On top I have a GMPP single plane intake, Aaron's elbow, f.a.s.t 92mm big mouth tb and under drive pulley. All of this is going into a 95 silverado rcsb. This will be backed with a TDP stg3 t56 and a diamond stg 3 clutch. I currently have the stg2 clutch but will be moving up to the stg3. I have an sts rearmount turbo kit that I will be using for parts only. It Has a bigger intercooler than what it comes with. I'm thinking of a 76mm turbo? I really don't want to pull the cam, will it be ok? Also, what about the 76mm turbo? What brand? I currently have a new walbro 255, will that suffice? What size injectors? I'm currently using green tops 42lbs. Any input would be great, I mainly have concerns on the cam. Thanks all.
