So your battery was draining, and you changed the optispark to fix it? O.o
Go out and buy yourself a digital multi-meter (if you don't already own one). Disconnect the negative battery terminal, and wire the multimeter in series between the battery terminal and the negative battery cable. Set your meter to current and see what the reading is. Generally anything above 50mA is high.
Then, start pulling fuses and see when the current drops to an acceptable level, you have your culprit and can begin fixing it.

i think he meant he changed his opti, then after that he started having a dead battery problem.
LT1 owners never could type
a common cause of battery drain is the stereo head unit, oem or aftermarket. you can try pulling that out of the dash and see if that helps.
Also the alarm system especially if an aftermarket one was installed can be the culprit. this is assuming your battery is good and not self discharging... unlikely for a new battery.
using a multimeter to see what current draw there is would be a good idea.
