Like said b-4, drive it awhile. You will get a better idea of what you want. E-body cars can be great canyon carvers with a small block and some suspension upgrades or a great drag car with the big block and some totally different suspension up grades. Get to know your car and decide what you want to do with it. You can chase down and tromp mustangs either track.
Nice car by the way.
Glad you have seen the light.
