Battery relocation, trunk or in car? 69 AMX 2 seater.

[813Demon340]

I'm looking for opinions on which is the best place to relocate my battery in my 69 AMX. I can move it behind the passenger seat in front of the rear wheel or move it to the trunk on the passenger side. I don't have a set of scales to see what the difference is between the two places. The trunk will move more weight rearward and farther out, behind the seat will move the weigh lower in the car but slightly inward. Moving weight rearward in the AMX is important because of the 97" wheelbase. Obviously there is no back seat in these cars, there will only be a rollbar. The car has an LS1, 6speed, glass bumpers, and has been on a diet where possible. Here is a picture of my previous stock 68 AMX on scales with steel bumpers and an AMC 390, auto. My car is probably around 200 lbs lighter, mostly in the front. The battery is an optima/sealed battery, FWIW.

So, behind seat or trunk? Or does it even matter? Thanks for the replies ahead of time!
