You should wait for your big cam dreams until after you switch to a manual transmission. I noticed a huge increase going from my C6 w 2400 stall to a top loader. Probably around 40hp I would guesstimate.
A big cam behind a stock stall auto box will kill the streetability. Hp gain for roller rockers, pushrods are around zero. You will not perceive the difference but they are nice/necessary parts to install with higher stressed valve train. Pistons will only give you power if they gain you more compression. They may be forged and lighter but then you need to basically balance and rebuild the whole bottom end of the motor. 4v heads, intake and headers would likely be the same money but gain you more. MSD box may gain you maybe 7-10 hp if all your stock stuff is in good shape. A Pertronix ignitor should be first on your list for ignition mods.
I believe your hp increase goals are optimistic. A GOOD cam may gain you 20 hp and keep most of the drivability. A cam with the gains you are after will kill street manners completely and have little to no drivability. You can't expect those kind of gains without totally reworking and matching the combination. Keeping your auto trans, I'd reccomend something like a Comp Cams XE262H. With matching valvesprings, etc.
