Get some aggressive gears, it won't add any power but you'll get into the powerband a lot sooner and it will definitely help 1/4 miles. I should note that your HP estimates are a little high. When compounding bolt ons you won't get as much HP typically advertised numbers are compared to stock cars.
Headers, exhaust (true dual), intake, gears, manifold for more mid range grunt and tune. I would guess on a dynojet this puts you somewhere around 320whp which is just about the peak of what you can squeeze out of an NA Z.
