I have an '07 SS/SC (Yellow). Right now the only performance mods i have are Stage II, the airbox mod with K&N E-1009, and (in a few days) a headers-back exhaust. i was planning on buying a smaller pulley, cooler spark plugs, a tune, and a CA heat exchanger. (And a torque dampener and tranny mounts)

I was just wondering at what point am i going to have to start getting any internal mods to my engine. I don't want to blow it before i have some fun. any info would be appreciated. thanks guys
