You'll gain even more from relocating the battery if its as far back as you can get. So not the high up near the rear seat back but even further back by the bumper. If a 20lb battery is placed say 2ft behind the rear axle, it will create a moment about the axle and is like removing an additional 5lb right off the Front axle of a 3600lb B-body.
That thinking is adequate for straight line racing. Putting the battery far back is not ideal in racing involving turns. The farther you have a weight from the center the more it wants to resist turning. That is why a mid engines car out handles a rear engine one, all else being equal. Under the rear seat pass side for the battery, ala VW Bug, is ideal, but likely no room.
No, in fact its pointedly true for any car trying to turn.
The OP B-body has nearly 60% of its weight on the front wheels. That's a huge amount of weight. Same with autoxcuda's A-body. So the Center of Gravity of those vehicles is quite forward the car's
geometric center. Its about the CG is where the vehicle will turn.
Its a fact that cars with a REAR weight bias both handle and brake better compared to a cars with a FRONT weight bias(
All mopars).
Its also a fact that moving the heavy weight of the Battery furthest to the Rear of the car will contribute the
MOST to moving the CG
rearward. But move the same Battery half as far and that contribution will be diminished accordingly.
Given the fuss of moving a battery, why bother moving it half way?Seems the Spare Tire well of an A-body(like all LX cars) would be a great place for a battery. But using a set of scales to pick the perfect spot would be ideal.
