Chassis Tuning

Batteries in the trunk?? Does it have long, or extended rear drag shocks?? You have to let the SS springs do their thing without topping out the shocks. My gut says you need a slightly taller gear, and a slightly higher stall. But that cars already going pretty good you know??
Battery is upfront, its still a street car and I dont want a switch until its not. I checked the rear shocks and they are about an inch longer than what the rear end hangs fully extended. I have a low first gear in the 904 in the car so I am not sure a gear change will matter, with the tire I have I am turning ove4 5500 at the stripe so there isn't a long way to go. I am pretty happy with the car overall but looking for information as how to tune the chassis to improve my 60'.
