Nova Z-28

I want to make my Nova handle awesome . The problem is I have a big block chevy . The front is very heavy, or out of balance. I relocated the battery to the trunk. Got rid of the front bumper inner shock units. trimmed a little weight off the inner bumper structure, removed heater core . The only thing I have left is a set of aluminum heads. But I don't have the cash right now.I want to put a rear sway bar on would this help my handling ?:confused: My 79 Z-28 had one and that car handled awesome. I would appreciate any help.:D
