Moving the engine back

My motor will be coming out this winter for repairs so i need a project. I was comptemplating moving the engine back a couple of inches (steering permited) and was wondering it it would be worth it. I know the work involved and it would be no issue but time and a small expense.
The car is a full race 68 Cuda that is gutted. Big block, big tire, on coilovers, ect....
May even look at moving the fire wall back far enough to hop the steering. (Brakes and gas not an issue)
Any thoughts?
