yes you have a bigger cam, more compression and an aggressive tune (COMPARED to a stock tuned vehicle). You might also have headers and other aftermarket upgrades.

PS. The ZR1;s engine from what I heard was LOWERED a tad, and the hood is far from being the traditional stock hood, it IS higher than the stock C6 hood.

How much power did you make and what were you're mods?

Mods were healthy blower cam, ported t-body, long tube headers, no cats, and free flowing mufflers. Manual tranny with 4.10 rear. It made 672 at the wheels.
