optima weighs close to stock.
for $20, you should get one and try it TypeR.

The biggie is going to be when it is hot . . . that's when I had most of my problems getting a car to fire . . . of course I was running 11.25 to 1 compression . . :P
I'd bet you could find smaller batteries that are in the 350-400CCA range and still weight a lot less.

your battery is also engineered to act as a capacitor. You would allow all of your electronics be wide open to a voltage spike. I.E. cooling fan turning on and off would produce a spike.... pressing the brake pedal...
Enough of a spike and you coulf fry your ECU.
You could replace the battery with a large capacitor once the car is running. Which would be lighter...
Although mot newer electronics are pretty good handling voltage spikes I wouldn't play with fire...
