We recently finished a c5z. It came in bone stock making 359RWHP. We installed 1 7/8 ARH W/ Cats, A 228/234 114 cam, and a A&A Vortech V3-Si. Thats 300+ hp increase with a mild set up.

wow excellent numbers. Very similiar to my car actually. I have a c5z with arh headers cam and ported heads with the a&a kit and made 535.4 peak tourqe and 590 peak hp but stopped the pull at 5900 rpm. Thanks for letting me see what my car could do if I decide to spin it up to the 6800rpm limit.
