Battery Relocation

How much of a difference will I notice if I relocate my battery to the trunk of my 68 notchback? I just completed my 408 build with aluminum eddy's, also replacing wiring harness and power to manual(Flaming River) steering box before reinstalling the engine. Does it help that much, or is it just for all out drag cars as mine is a street/strip car.
Thanks a Bunch!!
