Battery relocation for HANDLING (not drag) - best spot to mount?

That purple valiant calc’s to:
54.1% front
45.9% rear

here’s my car: no cage, without driver, without spare tire, front mounted battery.

1/2 tank of gas +/- 1/4 tank... gas load is a big deal. I should have noted it better.

57.1% front
43.9% rear


Just noticed my mistype. The numbers didn’t match my picture for my 68 barracuda coupe with no fiberglass, full interior. Correction:

57.3 % front

42.7 % rear

3209 lbs total: no driver, 1/2 tank gas +/- 1/4, front mount battery
