Default 2004 GTO build help??

2004 GTO, auto, BONE stock for now. Just wondering what kind of results I'll see out of a cam only engine with a stall and 150 shot? Not sure of cam or stall yet just digging for info now. I dont want a track car just something that sounds good and is efficient, and was looking at Texas Speed's Stage 1 Head/Cam package ( Precision Race Components LS6 64cc Stage 1.0 Cylinder Heads Fully CNC Ported & Assembled With GM Factory 2.00" Intake Valves, 1.55" Exhaust Valves, & LS6 Factory Valvetrain. Kit Also Includes TSP Hardened Pushrods & Your Choice Of Camshaft!!). Also has anyone out there experienced a clunk/pop from the rear end and it NOT been the CV's or u-joint's? Thanks guys.

The clunk is more than likely the rear subframe bushings, many 04's came without the top one's.

Ok i'll check that..I've only had it about a year and I'm not familiar with their suspension even still but I'll check that. It only does it when you put it in gear or go from neutral to reverse or when your coasting in a parking lot and its in 1st and you tap the throttle when it engages into 2nd.
