Earl,
As Terry said, you are going to throw the weight balance off a lot between front and rear. If you plan to drag race, then the extra weight should be placed behind the axle a little the way I understand it for better weight transfer. But it will be a bear to drive around corners. You want the weight as near 50/50 front to rear as you can get it for a good handling car. Mine was 51/49 and handled great. I did have my battery in the trunk.
