[blue00gt]

The motor itself will bolt right in. On top of the motor here are the things I can think of off the top of my head you'd need to address to make it work:
-taller hood
-fuel system
-flywheel and clutch to make your tranny work or ideally a beefier tranny so it will last
-computer or at least a tune if the 96 gt ECU can do it
-probably want a boost gauge
-wiring
-headers if it doesn't come with the manifolds
-better radiator
-mounting heat exchanger

Unless you can find a used one or one out of a wrecked Cobra for a bargain it gets pricey. FRPP is asking $11k just for the complete engine assembly.
