Re: 2001 GT engine
As said check your local salvage/pull a part yards.
If no luck there you could get quotes from Prestige Mustang in Georgia or MPS Auto Salvage. They part out mustangs and usually have 2v's, 4v's and pushrod 5.0's available.
I believe prices vary based on mileage, condition and whether you have a transmission paired with it.
